- Objective All treatment in Crohn's disease, although palliative, aims at restoring full health. The objective of this study was to compare health-related quality of life and psychosocial conditions in patients with Crohn's proctocolitis with a general population.Patients and methods One hundred and twenty-seven patients with Crohn's proctocolitis (median age 44 years, 44.1% men) were compared with 266 controls (median age 45 years, 50.7% men). A questionnaire consisting of the Short Form-36 (SF-36), the Psychological General Well-Being Index (PGWB) and a visual analogue scale (VAS) evaluating general health as well as questions regarding psychosocial conditions was used. Disease activity was evaluated by Best's modification of the classical Crohn's Disease Activity Index.Results Patients in remission had a health related quality of life similar to controls according to the SF-36 apart from general health where scores were lower (P < 0.01). Patients with active disease scored lower in all aspects of the SF-36 (P < 0.001 or P < 0.0001) as well as the PGWB (P < 0.0001). In a model for multiple regression including age, gender, concomitant small bowel disease, permanent stoma, previous colonic surgery, disease activity, duration, and aggressiveness, disease activity was the only variable negatively predicting all 8 domains of the SF-36 in the patient group (P < 0.001). The mean annual sick-leave for patients and controls were 33.9 and 9.5 days (P < 0.0001), respectively. Sixty-eight percent of the patients and 78.4% of the controls (P = 0.04) were married or cohabited, 67.7% and 78.0% (P = 0.04), respectively, had children.Conclusion The health related quality of life for patients with Crohn's proctocolitis in remission does not differ from the general population. The disease has, however, a negative impact on parenthood, family life and professional performance.

- 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.

- 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.

- Background: This study describes how surgery for Crohn colitis developed between 1970 and 1997, towards the end of which period limited resection and medical maintenance treatment was introduced.Methods: A cohort of 211 patients with Crohn colitis (115 population-based), of which 84 had a primary colonic resection (42 population-based), was investigated regarding indication for surgery, the time from diagnosis to operation, type of primary colonic resection, risk for permanent stoma and medication over four 7-year periods.Results: Comparison of the periods 1970-90 and 1991-97 revealed that active disease as an indication for surgery decreased from 64% to 25% ( P < 0.01) while stricture as an indication increased from 9% to 50% ( P < 0.001). Median time from diagnosis to operation increased from 3.5 to 11.5 years ( P < 0.01). Proctocolectomy or colectomy fell from 68.8% to 10% of the primary resections, whereas segmental resection increased from 31.2% to 90%. At the end of the first 7-year period, 26% had medical maintenance treatment, steroids or azathioprine taken by 7%. Corresponding figures for the last period were 70% and 49%. Patients diagnosed during the last two time-periods had less risk for surgery ( P = 0.017), permanent stoma ( P < 0.01) and total colectomy ( P < 0.01). Findings were similar in the population-based cohort.Conclusions: Current management of Crohn colitis implies a longer period between diagnosis and surgery, a reduced risk for surgery and permanent stoma, and the replacement of total colectomy by segmental resection.

- Objective. To evaluate the complications of the temporary loop ileostomy. Method. A retrospective study of 222 consecutive patients with low anterior resection, ileal pouch-anal anastomosis or continent ileostomy and a diverting loop ileostomy routinely fashioned during the primary operation. The loop ileostomy was closed in 213 patients (96%) during the minimum follow-up period of 15 months. Results. Four patients (2%) required preterm closure of the ostomy due to stomal retraction (n = 3) or bowel obstruction (n = 1). Four patients were readmitted due to transient bowel obstruction that resolved without surgery. After closure of the loop ileostomy a total of 27 patients (13%) had complications. In 7 patients emergency re-operation was done due to small bowel obstruction (n = 5) or intra-abdominal abscess (n = 2). Elective re-operation was done in 5 patients for hernia at the site of the previous stoma. Despite the use of a loop ileostomy there was 1 postoperative death after the initial operation in consequence of anastomotic leakage. There was 1 death in consequence of closure of the loop ileostomy after 3 weeks due to intra-abdominal sepsis and heart failure. Conclusion. In this series closure of the ostomy was associated with one death (0.5%) and overall ostomy-related morbidity included the need to re-operate in 6%.

- Approximately 50% of patients have an unsatisfactory functional result after traditional restorative rectal resection, and an even higher percentage, at least in the early postoperative period, suffers from urgency, frequent bowel movements, and occasional faecal incontinence. The rectal reservoir function is disturbed after restorative surgery. This is related to the size of the rectal remnant, the viscero-elastic properties, and the motility pattern of the neorectal wall, because segments of the remaining colon can only substitute for the rectum to a limited extent. A straight anastomosis is recommended when the rectal remnant (measured from the anal verge) is at least 7 to 8 cm. The side-to-end anastomosis is probably preferable to the end-to-end anastomosis. In contrast, a straight anastomosis at the levator plane cannot be recommended. If straight anastomosis is still considered, the descending colon should be used rather than the sigmoid colon. The colonic pouch was introduced to increase the neorectal volume and eliminate some of the functional disturbance associated with the reduced neorectal volume occurring after a straight colo-anal anastomosis. To obtain optimal functional results soon after surgery, a pouch should be used when the anastomosis is located 3 to 5 cm from the anal verge. The size of the pouch should not be too small. A staple line of 6 to 7 cm is a fair compromise between the low anterior resection syndrome and problems with evacuation. Since the descending colon has a thinner wall and often is healthier than the sigmoid colon, it should be the first choice for the anastomosis.

- Background: Reports that both intestinal and extraintestinal Crohn's disease (CD) had healed successfully after treatment with anti-tumor necrosis factor-alpha (TNF-a) antibody have strengthened the hypothesis that it has a role in the treatment of CD. The macrophage is one source of TNF-a. Intestinal mast cells are also thought to have a role in CD, but it is not known if human ileal mast cells express TNF-a. Aim: To find out whether TNF-a is expressed by mast cells in the ileal wall in CD patients and controls. Methods: TNF-a was sought immunohistochemically in full thickness specimens of ileal wall from patients with CD (histologically normal, n = 9, inflamed, n = 6) and controls (patients with colonic cancer, n = 8). Mast cells were identified by metachromasia and anti-mast cell tryptase immunoreactivity. Results: In all layers of the ileal wall, and in every specimen investigated, mast cells were the main cell type that expressed TNF-a immunoreactivity out of the TNF-a-labelled cells. The number of TNF-a-labelled mast cells was greater in the muscularis propria in patients compared with controls, both in uninflamed (1.7-fold, p < 0.05) and in inflamed bowel (4.6-fold, p < 0.002), greater in the submucosa in inflamed compared with uninflamed CD (1.6-fold, p < 0.01), and less in the lamina propria in inflamed compared with uninflamed CD (0.4-fold, p < 0.05). Conclusion: Mast cells are an important source of TNF-a in all layers of the ileal wall, and the increased density of TNF-a-positive mast cells in the submucosa and muscularis propria may contribute to the tissue changes and symptoms in CD.
