- 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.

In: Diseases of the Colon & Rectum. - : Ovid Technologies (Wolters Kluwer Health). - 0012-3706 .- 1530-0358. ; 45:1, s. 47-53
-
Journal article (peer-reviewed)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.

Simplified Evaluation of the Paradoxical Puborectalis Contraction With Surface Electrodes
- 2010
-
In: Diseases of the Colon & Rectum. - 0012-3706 .- 1530-0358. ; 53:6, s. 928-931
-
Journal article (peer-reviewed)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.

Long-term outcome after ileal pouch-anal anastomosis : function and health-related quality of life
- 2007
-
In: Diseases of the Colon & Rectum. - : Lippincott Williams & Wilkins. - 0012-3706 .- 1530-0358. ; 50:10, s. 1545-52
-
Journal article (peer-reviewed)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
-
In: Diseases of the Colon & Rectum. - : Lippincott Williams & Wilkins. - 0012-3706 .- 1530-0358. ; 63:2, s. 200-206
-
Journal article (peer-reviewed)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.

Patients Undergoing Ileoanal Pouch Surgery Experience a Constellation of Symptoms and Consequences Representing a Unique Syndrome: A Report from the Patient-Reported Outcomes After Pouch Surgery (PROPS) Delphi Consensus Study
- 2021
-
In: Diseases of the Colon & Rectum. - : LIPPINCOTT WILLIAMS & WILKINS. - 0012-3706 .- 1530-0358. ; 64:7, s. 861-870

Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- 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.
