- PURPOSE: Anal pathology occurs in 20 to 80 percent of patients with Crohn's disease in which abscesses, fistulas, and fissures account for considerable morbidity. The etiology is not clearly defined, but altered anorectal pressures may play a role. This study was designed to investigate anorectal physiologic conditions in patients with Crohn's disease compared with healthy controls.METHODS: Twenty patients with Crohn's disease located in the ileum (n = 9) or the colon (n = 11) without macroscopic proctitis or perianal disease were included. All were subjected to rectal examination, anorectal manometry, manovolumetry, and rectoscopy. Comparison was made with a reference group of 173 healthy controls of whom 128 underwent anorectal manometry, 29 manovolumetry, and 16 both examinations.RESULTS: Maximum resting pressure and resting pressure area were higher in patients than in controls (P = 0.017 and P = 0.011, respectively), whereas maximum squeeze pressure and squeeze pressure area were similar. Rectal sensitivity was increased in patients expressed as lower values both for volume and pressure for urge (P = 0.013 and P = 0.014, respectively) as well as maximum tolerable pressure (P = 0.025).CONCLUSIONS: This study demonstrates how patients with Crohn's disease without macroscopic proctitis have increased anal pressures in conjunction with increased rectal sensitivity. This may contribute to later development of anal pathology, because increased intra-anal pressures may compromise anal circulation, causing fissures, and also discharging of fecal matter into the perirectal tracts, which may have a role in infection and fistula development.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: Segmental resection for Crohn's colitis is controversial. Compared with subtotal colectomy, segmental resection is reported to be associated with a higher rate of re-resection. Few studies address this issue, and postoperative functional outcome has not been reported previously. This study compared segmental resection to subtotal colectomy with anastomosis with regard to re-resection, postoperative symptoms, and anorectal function.METHODS: Fifty-seven patients operated on between 1970 and 1997 with segmental resection (n = 31) or subtotal colectomy (n = 26) were included. Reoperative procedures were analyzed by a life-table technique. Segmentally resected patients were also compared separately with a subgroup of subtotally colectomized patients (n = 12) with similarly limited colonic involvement. Symptoms were assessed according to Best's modified Crohn's Disease Activity Index and an anorectal function score.RESULTS: The re-resection rate did not differ between groups in either the entire study population (P = 0.46) or the subgroup of patients with comparable colonic involvement (P = 0.78). Segmentally resected patients had fewer symptoms (P = 0.039), fewer loose stools (P = 0.002), and better anorectal function (P = 0.027). Multivariate analysis revealed the number of colonic segments removed to be the strongest predictive factor for postoperative symptoms and anorectal function (P = 0.026 and P = 0.013, respectively).CONCLUSION: Segmental resection should be considered in limited Crohn's colitis.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE:Paradoxical puborectalis contraction during defecation is one possible explanation for constipation. The degree of paradoxical contraction can be evaluated by intramuscular electromyography from the puborectalis and external anal sphincter muscles. This study aimed to determine whether a noninvasive technique with surface electrodes placed over the subcutaneous part of the external anal sphincter is feasible in the evaluation of paradoxical activity.METHODS:Twenty-five patients with constipation were studied. Sphincter muscle activity during strain and squeeze maneuvers was recorded using surface electrodes placed 1 cm from the anal verge. In addition, intramuscular recordings were made simultaneously from the external anal sphincter and puborectalis muscles. The degree of paradoxical activation was calculated as a strain/squeeze index. The patients were examined either in the left lateral position or sitting on a commode.RESULTS:The study revealed significant (P < .01) correlations between indices obtained from the surface anal sphincter recordings and the intramuscular recordings (from the external anal sphincter and the puborectalis muscles).CONCLUSION: Surface recordings from the external anal sphincter seem to be an equally reliable, less time consuming, and less painful alternative to invasive measurements of paradoxical activity. In a few patients, however, invasive recordings may still be required.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The principal aim of this study was to assess long-term pouch durability and health-related quality of life in an original series of patients operated on with a continent ileostomy. PATIENTS: Data from 68 of 88 patients who had a continent ileostomy performed at Sahlgrenska University Hospital between 1967 and 1974 were analyzed. Median age at follow-up was 60 (range, 40-89) years and median follow-up was 31 (range, 29-36) years. METHODS: Patients were sent a questionnaire on pouch function along with the Short Form-36 Health Survey 2.0. A random age-matched and gender-matched sample was drawn from the Swedish national Short Form-36 Health Survey norm database to compare with the patient group. RESULTS: The majority of the patients reported good physical condition and satisfactory pouch function. Patients evacuated the pouch a median of four times every 24 hours. Twelve patients (18 percent) had leakages. Forty-four patients (65 percent) had had at least one postoperative revision to restore continence. Generally minor peristomal skin irritation occurred in seven patients (10 percent). Patients with concurrent complaints (mostly age related) reported poorer health-related quality of life. Nevertheless, 78 percent of the patients rated their overall health as good, very good, or excellent. The patients' Short Form-36 Health Survey scores were comparable to reference values. CONCLUSIONS: Although revisional operations may be needed to restore continence, continent ileostomy has a good durability. Pouch function was satisfactory and patients' satisfaction was high. Health-related quality of life levels were similar to those of the general population.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: This study was designed to investigate long-term pouch function and health-related quality of life in a single, large cohort of patients with ileal pouch-anal anastomosis for ulcerative colitis. METHODS: Data from 370 patients were included in the study. Thirty-nine patients (11 percent) did not have a functioning pouch (failures) but were included in the health-related quality of life analyses. Pouch function (Oresland score) and health-related quality of life (Short Form-36) were evaluated by postal questionnaires. A total of 88 percent of the patients with a functioning ileal pouch-anal anastomosis returned the questionnaires vs. 76 percent of the failures. Median follow-up time after ileal pouch-anal anastomosis was 15 years vs. 11 years after failure. An age-matched and gender-matched reference sample (n = 286) was randomly drawn from the Swedish Short Form-36 database. RESULTS: Median bowel frequency was six per 24 hours: 76 percent emptied the reservoir at night, 23 percent had urgency, 12 percent had evacuation difficulties, and 17 percent experienced soiling during the day. Fifty-two percent of the males and 32 percent of the females suffered from soiling at night. More than one-half of the patients had occasional perianal soreness, 6 percent considered the pouch to be a social handicap, and 94 percent were satisfied with their pouch. Patients with a functioning ileal pouch-anal anastomosis did not differ from the reference sample on any Short Form-36 domain, except for a reduced score in General Health (P = 0.02). Pouch function was positively correlated to health-related quality of life. Patients with pouch failure had reduced health-related quality of life in most domains. CONCLUSIONS: Patients' satisfaction is high and functional outcome is good after ileal pouch-anal anastomosis. Poor pouch function affects health-related quality of life negatively. Patients with failure after ileal pouch-anal anastomosis are substantially limited in a variety of health-related quality of life domains.

Does Smoking Cessation Reduce Surgical Recurrence After Primary Ileocolic Resection for Crohns Disease?
- 2020
-

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Tobacco smoking is a known risk factor for recurrence of Crohns disease after surgical resection. OBJECTIVE: This study assessed the effect of smoking cessation on long-term surgical recurrence after primary ileocolic resection for Crohns disease. DESIGN: A retrospective review of a prospectively maintained database was conducted. SETTINGS: Patient demographic data and medical and surgical details were combined from 2 specialist centers. After ethical approval, patients were contacted in case of missing data regarding smoking habit. PATIENTS: All patients undergoing ileocolic resection between 2000 and 2012 for histologically confirmed Crohns disease were included. Those with previous intestinal resection, strictureplasty for Crohns disease, leak after ileocolic resection, or who were never reversed were excluded. MAIN OUTCOME MEASURES: The primary end point was surgical recurrence measured by Kaplan-Meier survival analysis and secondary medical therapy at time of follow-up. RESULTS: Over a 12-year period, 290 patients underwent ileocolic resection. Full smoking data were available for 242 (83%) of 290 patients. There were 169 nonsmokers (70%; group 1), 42 active smokers at the time of ileocolic resection who continued smoking up to last follow-up (17%; group 2), and 31 (13%) who quit smoking after ileocolic resection (group 3). The median time of smoking exposure after ileocolic resection for group 3 was 3 years (interquartile range, 0-6 y), and median follow-up time for the whole group was 112 months (9 mo; interquartile range, 84-148 mo). Kaplan-Meier survival analysis showed a significantly higher surgical recurrence rate for group 2 compared with group 3 (16/42 (38%) vs 3/31 (10%); p = 0.02; risk ratio = 3.9 (95% CI, 1-12)). In addition, significantly more patients in group 2 without surgical recurrence received immunomodulatory maintenance therapy compared with group 3 (12/26 (46%) vs 4/28 (14%); p = 0.01; risk ratio = 3.2 (95% CI, 1-9)). LIMITATIONS: The study was limited by its retrospective design and small number of patients. CONCLUSIONS: Smoking cessation after primary ileocolic resection for Crohns disease may significantly reduce long-term risk of surgical recurrence and is associated with less use of maintenance therapy.

- BACKGROUND: Functional outcomes after ileoanal pouch creation have been studied; however, there is great variability in how relevant outcomes are defined and reported. More importantly, the perspective of patients has not been represented in deciding which outcomes should be the focus of research. OBJECTIVE: The primary aim was to create a patient-centered definition of core symptoms that should be included in future studies of pouch function. DESIGN: This was a Delphi consensus study. SETTING: Three rounds of surveys were used to select high-priority items. Survey voting was followed by a series of online patient consultation meetings used to clarify voting trends. A final online consensus meeting with representation from all 3 expert panels was held to finalize a consensus statement. PATIENTS: Expert stakeholders were chosen to correlate with the clinical scenario of the multidisciplinary team that cares for pouch patients, including patients, colorectal surgeons, and gastroenterologists or other clinicians. MAIN OUTCOME MEASURES: A consensus statement was the main outcome. RESULTS: One hundred ninety-five patients, 62 colorectal surgeons, and 48 gastroenterologists or nurse specialists completed all 3 Delphi rounds. Fifty-three patients participated in online focus groups. One hundred sixty-one stakeholders participated in the final consensus meeting. On conclusion of the consensus meeting, 7 bowel symptoms and 7 consequences of undergoing ileoanal pouch surgery were included in the final consensus statement. LIMITATIONS: The study was limited by online recruitment bias. CONCLUSIONS: This study is the first to identify key functional outcomes after pouch surgery with direct input from a large panel of ileoanal pouch patients. The inclusion of patients in all stages of the consensus process allowed for a true patient-centered approach in defining the core domains that should be focused on in future studies of pouch function.

- PURPOSE: Sexual dysfunction after total mesorectal excision may be caused by injury to the autonomic nerves. During surgery, nerve identification is not always achieved, and, to date, there has been no method to objectively confirm nerve preservation. The aim of this study was to assess the efficacy of a nerve-stimulating device (CaverMap) to assist in the intraoperative identification of the autonomic nerves during total mesorectal excision, and objectively confirm nerve preservation after proctectomy is completed. PATIENTS AND METHODS: Sexually active consecutive male patients undergoing total mesorectal excision were prospectively enrolled in this study. During pelvic dissection, the surgeon attempted to localize the hypogastric and cavernous nerves. CaverMap was used to confirm these findings and to facilitate the identification in cases of uncertainty. At the completion of proctectomy, the nerves were restimulated to ensure preservation. Factors that could affect the surgeon's ability to localize the nerves and CaverMap to confirm this were evaluated. RESULTS: Twenty-nine male patients with a median age of 58 years were enrolled in this study. An attempt to visualize the hypogastric nerves during dissection was made in 26 patients; the surgeon was able to identify the nerves in 19 (73 percent) patients. CaverMap successfully identified the nerves in six of the seven remaining patients, and failed to identify them in only one case. An attempt to localize the cavernous nerves during dissection was made in 13 patients, of which localization was successful in 8 (61.5 percent) patients. CaverMap improved the identification rate in four of the remaining five patients. After proctectomy, CaverMap successfully confirmed the preservation of both hypogastric and cavernous nerves in 27 of 29 (93 percent) patients. A history of previous surgery statistically correlated with failure to identify the hypogastric nerves by the surgeon (P = 0.005). There were no adverse events related to use of the device. CONCLUSION: CaverMap may be a useful tool to facilitate identification of the pelvic autonomic nerves during total mesorectal excision and to objectively confirm nerve preservation.

- Nine women and five children with severe chronic constipation received behavioral medicine therapy. Before treatment, all patients had a paradoxical contraction of the external anal sphincter at defecation attempts as demonstrated with electromyography and/or anorectal manometry. An electromyographic biofeedback device connected to an anal probe was used for the training that was performed on a regular toilet seat during five 1-hour sessions. Thirteen of the patients improved considerably and could learn to defecate spontaneously, and the use of laxatives ceased or diminished. Simultaneously with improvement, the paradoxical anal contraction disappeared. The results remained after 6 months, although two of the patients had received booster sessions of biofeedback training during follow-up.

- PURPOSE: NASHA Dx gel has been used extensively for treatments in the field of urology. This study was performed to evaluate NASHA Dx gel as an injectable anal canal implant for the treatment of fecal incontinence. METHODS: Thirty-four patients (5 males, 29 females; median age, 61 years; range, 34 to 80) were injected with 4 x 1 ml of NASHA Dx gel, just above the dentate line in the submucosal layer. The primary end point was change in the number of incontinence episodes and a treatment response was defined as a 50 percent reduction compared with pretreatment. All patients were followed up at 3, 6, and 12 months. RESULTS: The median number of incontinence episodes during four weeks was 22 (range, 2 to 77) before treatment, at 6 months it was 9 (range, 0 to 46), and at 12 months it was 10 (range, 0 to 70, P = 0.004). Fifteen patients (44 percent) were responders at 6 months, compared with 19 (56 percent) at 12 months. No long-term side effects or serious adverse events were reported. CONCLUSIONS: Submucosal injection of NASHA Dx gel is an effective treatment for fecal incontinence. The effect is sustained for at least 12 months. The treatment is associated with low morbidity.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Ileorectal anastomosis in patients with ulcerative colitis results in decreased postoperative morbidity and better functional outcome but leads to increased risk for rectal cancer compared with IPAA. OBJECTIVE: This study aims to compare ileorectal anastomosis with IPAA in ulcerative colitis by using a decision model. DESIGN: A Markov simulation model was designed to simulate clinical events of ileorectal anastomosis and IPAA over a time horizon of 40 years with time cycles of 1 year. All probabilities and utilities were derived from observational studies, identified after a systematic literature search using MEDLINE. Primary outcomes were life-years and quality-adjusted life-years. Deterministic and probabilistic sensitivity analyses were performed. SETTINGS: A decision model using Markov simulation was designed. PATIENTS: The base case was a 35-year-old patient with ulcerative colitis and a relatively preserved rectum. MAIN OUTCOMES MEASURES: The primary outcome measures were (quality-adjusted) life-years. RESULTS: The model resulted in lower life-years (36.22 vs 37.02) and higher quality-adjusted life-years (33.42 vs 31.57) for ileorectal anastomosis. This was confirmed after probabilistic sensitivity analysis. The model was sensitive to the utility of ileorectal anastomosis, IPAA, and end-ileostomy. A higher proportion of patients with ileorectal anastomosis will develop rectal cancer (7.6% vs 3.2%) and 43.5% of all patients with ileorectal anastomosis will end with an ileostomy as opposed to 23.0% of all patients with IPAA. LIMITATIONS: The study was limited by characteristics inherent to modeling studies, including assumptions necessary to build the model, data input based on best available but often limited evidence, and unavoidable extra- and interpolation of data. CONCLUSIONS: Ileorectal anastomosis was the preferred treatment option when quality-adjusted life-years were the outcome, with higher life-years for IPAA. This model highlights that both surgical strategies are useful in patients who have ulcerative colitis with a relatively spared rectum. See Video Abstract at http://links.lww.com/DCR/B249.

- BACKGROUND: High iron levels can increase the formation of noxious oxygen radicals, which are thought to promote carcinogenesis. OBJECTIVE: The aim of this prospective study was to determine whether iron biomarkers and HFE genotypes, which influence iron regulation, constitute risk factors for colorectal cancer. DESIGN: This is a prospective nested case-referent study. SETTINGS: The study was performed within the population-based Northern Sweden Health and Disease Study. PATIENTS: The study included 226 cases of colorectal cancer and 437 matched referents. MAIN OUTCOME MEASURES: Conditional regression analysis was performed. Adjustments for smoking, smoking and BMI, and HFE C282Y and H63D were performed. RESULTS: The highest quintile of total iron-binding capacity showed significantly higher risk for colorectal cancer, unadjusted OR 2.35 (95% CI 1.38-4.02). When stratified by sex, the findings were only present in women (OR 3.34 (95% CI 1.59-7.02)). Ferritin was associated with reduced risk throughout quintiles 2 to 5 both in univariate and multivariate models. LIMITATIONS: Colorectal cancer may influence iron markers because of occult bleeding. Homozygotes for HFE C282Y were too few to make conclusions for this group. The relatively short follow-up time might be insufficient to detect risk of iron biomarkers. CONCLUSIONS: High iron levels do not increase the risk of colorectal cancer. HFE genotypes influencing iron uptake had no effect on colorectal cancer risk.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The optimal type of neoadjuvant therapy regimen in rectal cancer is contentious. OBJECTIVE: This study aimed to review the impact of neoadjuvant therapy on oncological outcomes and complications (short and long term) in patients undergoing total mesorectal excision for rectal cancer. DATA SOURCES: An electronic search of MEDLINE, PubMed, EMBASE, and the Cochrane Database of Collected Reviews was performed through March 2010. STUDY SELECTION: Key-word combinations including rectal cancer, total mesorectal excision, radiotherapy, chemotherapy, endorectal ultrasound, and magnetic resonance imaging were used to identify randomized control trials where chemotherapy and/or radiotherapy were deployed before resectional surgery. INTERVENTION(S): Patients underwent total mesorectal excision for rectal cancer who did and did not receive preoperative chemotherapy and/or radiotherapy. MAIN OUTCOME MEASURES: The main outcome measures comprised the impact of the addition of neoadjuvant therapy to total mesorectal excision on the perioperative complication rate, the pathological complete response rate, the rate of local recurrence, and long- term treatment-related complications. RESULTS: A total of 12 randomized control trials involving 9410 patients were included. Both short-course radiotherapy and long-course chemoradiation can offer a relative risk reduction of 50% in local recurrence in appropriately selected patients with stage II and III rectal cancer. This oncological benefit comes at the cost of a relative risk increase of 50% in both acute treatment-related toxicity and long-term anorectal dysfunction. LIMITATIONS: Preoperative staging provides only an estimate of the "true" tumor stage that can only be determined by histological assessment of the tumor specimen which renders appropriate patient selection challenging. CONCLUSIONS: The current treatment trade-off of a relative risk reduction of local recurrence of 50% at the cost of a relative increase of 50% in treatment-related complications underpins the need for more accurate patient staging and more precise delivery of neoadjuvant therapy.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Anorectal function after rectal surgery with low anastomosis is often impaired. Outcome of long-term anorectal function is poorly understood but may improve over time.OBJECTIVE: We evaluated anorectal function 5 years after low anterior resection for cancer with regard to whether patients had a temporary stoma at initial resection. The objective of this study was to assess changes in anorectal function over time by comparing the results with anorectal function 1 year after rectal resection.DESIGN: This study was a secondary end point of a randomized, multicenter controlled trial.SETTINGS: The study was conducted at 21 Swedish hospitals performing rectal cancer surgery from 1999 to 2005.PATIENTS: Patients included were those operated on with low anterior resection.INTERVENTIONS: Patients were randomly assigned to receive or not receive a defunctioning stoma.MAIN OUTCOME MEASURES: We evaluated anorectal function in patients who were initially randomly assigned to the defunctioning stoma or no stoma group, who had been free of stoma for 5 years, by means of using a standardized patient questionnaire. Questions addressed stool frequency, urgency, fragmentation of bowel movements, evacuation difficulties, incontinence, lifestyle alterations, and patient preference regarding permanent stoma formation. Results were compared with the same patient cohort at 1-year follow-up.RESULTS: A total of 123 patients answered the bowel function questionnaire (65 in the no-stoma group and 58 in the stoma group). No differences were found between groups regarding the number of passed stools, need for medication to open the bowel, evacuation difficulties, incontinence, and urgency. General well-being was significantly better in the no-stoma group (p = 0.033). Comparison with anorectal function at 1 year showed no further changes over time.LIMITATIONS: The study was based on a limited sample size (n = 123) and formed a secondary end point of a randomized trial.CONCLUSIONS: Anorectal function was impaired for many patients, but the temporary presence of a defunctioning stoma after rectal resection did not affect long-term outcome. Anorectal function did not change between 1-year and 5-year follow-up.

- BACKGROUND: Anorectal function after low anterior resection of the rectum for cancer is often impaired, and long-term outcome has not frequently been reported.OBJECTIVE: We evaluated anorectal function 12 years after rectal resection with regard to whether patients had a defunctioning temporary stoma at the initial rectal resection.DESIGN: An exploratory cross-sectional investigation of a previously randomized study population.SETTINGS: Twenty-one Swedish hospitals performing rectal cancer surgery during a 5-year period participated in the trial.PATIENTS: Patients operated on with low anterior resection for cancer were included.INTERVENTIONS: Patients were randomly assigned to receive or not receive a temporary defunctioning stoma.MAIN OUTCOME MEASURES: We evaluated anorectal function 12 years after low anterior resection in patients who were initially randomly assigned to temporary stoma or not, by means of using the low anterior resection syndrome score questionnaire, which assesses incontinence for flatus, incontinence for liquid stools, defecation frequency, clustering, and urgency. Self-perceived health status was evaluated by the EQ-5D-3L questionnaire.RESULTS: Eighty-nine percent (87/ 98) of the patients responded to the questionnaires, including 46 with and 41 without an initial temporary stoma. Patient demography was comparable between the groups. No differences regarding major, minor, and no low anterior resection syndrome categories were found between the groups. The stoma group had increased incontinence for flatus (p = 0.03) and liquid stools (p = 0.005) and worse overall low anterior resection syndrome score (p = 0.04) but no differences regarding frequency, clustering, and urgency.LIMITATIONS: The study was limited by its sample size (n = 98) based on a previously randomized trial population (n = 234).CONCLUSIONS: After low anterior resection for cancer, the incidence of the categories major, minor, and no low anterior resection syndrome were comparable in the stoma and the no-stoma groups. Incontinence for flatus and liquid stools was more commonly reported by patients who were randomly assigned to temporary stoma, as compared with those without, which may indicate an association between temporary stoma and impaired anorectal function.

- Purpose This study was designed to demonstrate the usefulness of a method of regional anesthesia for circular stapler anopexy for prolapsing hemorrhoids. Methods Thirty-three patients consented to stapled anopexy under perianal local anesthesia. Eighteen patients with stapled anopexy under general anesthesia were controls. The perianal block was applied with 40 ml of ropivacaine, 4.75 mg/ml, injected immediately peripheral to the external sphincter. A submucosal block with 15 ml of ropivacaine, 2 mg/ml, was added after applying the pursestring suture. Postoperative pain was rated by the patient for 14 days by using a ten-point visual analogue scale. Patients also submitted a preoperative and postoperative (3–6 months) symptom questionnaire to rate anal symptoms. Results No operation was converted to general anesthesia. Operation time was similar in both groups. All patients in the local anesthesia group were pain free at discharge. The sums of pain scores during 14 days for daily average pain and peak pain were similar in both groups (average pain 23 (local anesthesia) vs. 35 (general anesthesia); peak pain 39 (local anesthesia) vs. 50 (general anesthesia); P > 0.05). The preoperative symptom scores were 7.8 (local anesthesia) vs. 8.9 (general anesthesia) points, and the follow-up scores were 2.2 (local anesthesia) and 2.7 (general anesthesia), a significant improvement (P = 0.001) in both groups but not different between groups. Conclusions A perianal local block is easy to apply and has a high degree of acceptance among patients. The operation time, postoperative pain, and success rates of the operation equaled those of stapled anopexy performed under general anesthesia. The advantages are quicker turnover between cases and simpler management of pain-free postoperative patients in day surgery.

- PURPOSE: This study was designed to evaluate possible social and geographic factors that could have an impact on quality of life in patients after abdominoperineal excision of the rectum. Although the number of patients with rectal cancer who need to be treated with abdominoperineal excision of the rectum and construction of permanent colostomy has greatly decreased in the past, there is still controversy about the influence on quality of life caused by this procedure. METHODS: In a prospective trial, patients operated on for low rectal cancer by abdominoperineal excision of the rectum were evaluated by a quality of life questionnaire, modified from The American Society of Colon and Rectal Surgeons questionnaire, to assess fecal incontinence. The results for the four domains of quality of life (lifestyle, coping behavior, embarrassment, depression), as well as for subjective general health, were evaluated with regard to age, gender, education, and geographic origin in univariate and multivariate analyses. RESULTS: Thirteen institutions in 11 countries included data from 257 patients. Although the analysis of general health did not reveal any significant differences, the analysis of the four quality of life domains showed the significant influence of geographic origin. The presence of a permanent colostomy showed a consistently negative impact on patients in southern Europe as well as for patients of Arabic (Islamic) origin. On the other hand, age, gender, and educational status did not reveal a statistically significant influence. CONCLUSIONS: This is the first study to show the influence of geographic origin on quality of life of patients with a permanent colostomy. Possible factors that may influence the outcome of patients after surgical treatment of rectal cancer, such as weather, religion, or culture, should be taken into account when quality of life evaluations are considered.

- Sporadic reports of epithelial dysplasia and the occasional development of adenocarcinoma in the ileal pouch mucosa have recently appeared in the literature, pointing toward yet another long-term complication of the continent ileostomy and the pelvic pouch. The incidence of dysplasia and the risk for developing cancer has not been critically evaluated, however, and the reports are contradictory, with most having short observation times. The purpose of this study was to report long-term mucosal adaptation patterns and the incidence of dysplasia in Kock pouches after a mean follow-up of 30 years for patients previously operated on for ulcerative proctocolitis.Two sets of two pathologists each (in Gothenburg, Sweden, and Manchester, United Kingdom) examined sequential, small-intestinal biopsy specimens from 40 patients with Kock pouch to observe long-term epithelial changes, with particular reference to the presence of dysplasia.There was full agreement between the two groups regarding the absence of high-grade dysplasia and invasive carcinoma (Categories 4 and 5 of the Vienna classification). There was, however, significant disagreement in reporting the frequency of low-grade and indefinite categories of dysplasia (Categories 2 and 3, of the Vienna classification). No attempt was made to report the differences within each set of pathologists.Because no case of high-grade dysplasia or invasive carcinoma was found in this study after a mean follow-up of 30 years, we conclude that it is very unlikely for invasive carcinoma to be a complication in ileal pouch mucosa.

- BACKGROUND: Current studies reporting on the risk of smoking and development of symptomatic diverticular disease have reported conflicting results.OBJECTIVE: The aim of this study was to investigate the association between smoking and symptomatic diverticular disease.DESIGN: This is a cohort studySETTINGS: : Information was derived from the Swedish Construction Workers Cohort 1971-1993.PATIENTS: Patients were selected from construction workers in Sweden.MAIN OUTCOME MEASURES: The primary outcome measured was the development of symptomatic diverticular disease and complicated diverticular disease (abscess and perforation) as identified in the Swedish Hospital Discharge Register. Adjusted relative risks of symptomatic diverticular disease according to smoking status were estimated by using negative binomial regression analysis.RESULTS: In total, the study included 232,685 men and 14,592 women. During follow-up, 3891 men and 318 women had a diagnosis of later symptomatic diverticular disease. In men, heavy smokers (≥15 cigarettes a day) had a 1.6-fold increased risk of developing symptomatic diverticular disease compared with nonsmokers (adjusted relative risk, 1.56; 95% CI, 1.42-1.72). There was evidence of a dose-response relationship, because moderate and ex-smokers had a 1.4- and 1.2-fold increased risk compared with nonsmokers (adjusted relative risk, 1.39; 95% CI, 1.27-1.52 and adjusted relative risk, 1.14; 95% CI, 1.04-1.27). These relationships were similar in women, but the risk estimates were less precise owing to smaller numbers. Male ever-smokers had a 2.7-fold increased risk of developing complicated diverticular disease (perforation/abscess) compared with nonsmokers (adjusted relative risks, 2.73; 95% CI, 1.69-4.41).LIMITATIONS: We were unable to account for other confounding variables such as comorbidity, prescription medication, or lifestyle factors.CONCLUSIONS: Smoking is associated with symptomatic diverticular disease in both men and women and with an increased risk of developing complicated diverticular disease.

- BACKGROUND: Fecal incontinence is a rare but well-known adverse effect of hemorrhoidectomy. OBJECTIVE: The objective of this study was to identify possible reasons for incontinence after hemorrhoidectomy. DESIGN: We conducted a retrospective comparative study. SETTINGS: The study was performed in 1 university hospital and 1 general district hospital serving 2 counties in central Sweden. PATIENTS: In a cohort of 418 patients with consecutive Milligan hemorrhoidectomies, 40 reported fecal incontinence that was attributed to surgery. Of these, 19 patients agreed to participate. Fifteen age- and sex-matched patients from the same cohort who were operated on, but without symptoms of incontinence, were also studied, as was a third reference group of 19 age- and sex-matched persons serving as a population-based control group. INTERVENTION: All of the participants answered a bowel function questionnaire and underwent clinical evaluation, including rectoscopy, anal manometry, saline infusion test, and endoanal ultrasound. MAIN OUTCOME MEASURES: We evaluated anal resting and squeeze pressures, sphincter defects, and continence function. RESULTS: The symptomatic patients had higher incontinence scores than the control groups (p = 0.00002). The mean resting pressure at the high-pressure zone was also reduced in this group (p = 0.047). External sphincter injuries were detected in 4 (20%) of 19 subjects compared with none in the control group (p = 0.11). Saline infusion test in the patients reporting incontinence showed reduced ability to hold liquids compared with healthy controls (p = 0.004). LIMITATIONS: This study was limited by selection bias and limited numbers in the groups. CONCLUSIONS: In the group of patients reporting incontinence after hemorrhoidectomy, there was a proportion with sphincter defects and impaired sphincter function. These results indicate a need for cautious patient selection and improved or alternative surgical techniques.

- BACKGROUND: Low anterior resection syndrome is common after sphincter-sparing surgery, but it is unclear to what extent anastomotic leakage after anterior resection contributes to this condition. OBJECTIVE: The aim of this study is to assess the long-term effect of anastomotic leakage on the occurrence of major low anterior resection syndrome. DESIGN: This is a retrospective observational cohort study evaluating low anterior resection syndrome 4 to 11 years after index surgery. After propensity score-matching using the covariates sex, age, tumor stage, comorbidity, neoadjuvant treatment, extent of mesorectal excision, and defunctioning stoma at index surgery, the effect of anastomotic leakage on low anterior resection syndrome was investigated using relative risk and 95% CI. SETTINGS: This multicenter study included patients from 15 Swedish hospitals between 2007 and 2013. PATIENTS: Patients who underwent anterior resection for rectal cancer were included. MAIN OUTCOME MEASURES: Outcome measures included patient-reported major low anterior resection syndrome, obtained via a postal questionnaire that included a question on stoma status. RESULTS: Among 1099 patients, 653 (59.4%) responded in at a median of 83.5 (interquartile range 66 to 110) months postoperatively. After excluding patients with residual stoma or incomplete responses, 544 remained; of these, 42 had anastomotic leakage. Patients with anastomotic leakage were more likely to have major low anterior resection syndrome (66.7% [28/42]) than patients without leakage (45.8% [230/502]). After matching, anastomotic leakage was significantly related to major low anterior resection syndrome (relative risk 2.3; 95% CI 1.4-3.9) and the individual symptom of urgency (relative risk 2.1; 95% CI 1.1-4.1). LIMITATIONS: This study was limited by its retrospective observational study design. CONCLUSIONS: In long-term follow-up, major low anterior resection syndrome is common after anterior resection for rectal cancer. Anastomotic leakage appears to increase the risk of major low anterior resection syndrome, with urgency as a major contributing symptom.
