- Background and aim: A 12 month, multicentre, randomised, double blind, placebo controlled, phase 3, dose-response study was carried out. Exisulind inhibits tumour growth by induction of apoptosis. The aim of our study was to investigate if exisulind induces regression of sporadic colonic adenomas. Patients and methods: A 12 month multicentre randomised double blind placebo controlled phase 3 dose response study was carried out. At baseline colonoscopy, left sided polyps (3-10 mm) were tattooed, measured, and left in place. Subjects received exisulind 200 or 400 mg, or placebo daily. Follow up sigmoidoscopy was performed after six months, and removal of any remaining polyps at the 12 month colonoscopy. The primary efficacy variable was change in polyp size from baseline. Results: A total of 281 patients were enrolled and randomised, 155 (55%) fulfilled the criteria for the intention to treat (ITT) analysis and 114 (41%) fulfilled the criteria for the efficacy evaluation analysis (patients who underwent the 12 month colonoscopy). The decrease in median polyp size was significantly greater (p = 0.03) in patients who received exisulind 400 mg (-10 mm2) compared with those who received placebo (-4 mm2). Complete or partial response was significantly higher in the exisulind 400 mg group (54.6%) compared with the placebo group (30.2%), and disease progression was significantly lower (6.1% v 27.9%) (p = 0.04 and 0.02, respectively). Increased liver enzymes (8.4%) and abdominal pain (14.7%) were also reported at a greater frequency in the exisulind 400 mg group. Conclusion: Exisulind caused significant regression of sporadic adenomatous polyps but was associated with more toxicity. This model of polyp regression, short in its term and involving a comparatively small patient sample size, may be the best available tool to assess a therapeutic regimen before launching into large preventive clinical studies.

- BACKGROUND. Colorectal cancer is one of the most common forms of cancer in the Western world. Staging based on histopathology is currently the most accurate predictor of outcome after surgery. Colorectal cancer is curable if treated at an early stage (stage I-III). However, for tumors in stages II and III there is a great need for tests giving more accurate prognostic information defining the patient population in need of closer follow-up and/or adjuvant therapy. Furthermore, tests that provide prognostic information preoperatively could provide a guide both for preoperative oncologic treatment and the surgical procedure. METHODS. Peripheral blood mononuclear cells (PBMCs) were isolated preoperatively, within a week before primary surgery, from 39 patients undergoing surgery for colorectal cancer. The PBMCs were cultured in vitro for 24 hours in the presence of autologous serum and lipopolysaccharide (LPS). Interleukin-6 (IL-6) production was measured with enzyme-linked immunosorbent assay (ELISA). Staging based on histopathology was performed in all patients. Patients were followed for at least 54 months. RESULTS. A production of >5000 pg/mL of IL-6 identified colorectal cancer patients with a poor prognosis. Eight out of 13 patients with >5000 pg/mL IL-6 died from cancer within the follow-up period, whereas no cancer-related deaths were recorded among 21 patients with 5000 pg/mL IL-6 or less. A multivariate Cox regression analysis, stratified for T- and N-stage, identified IL-6 production as an independent prognostic factor. CONCLUSIONS. IL-6 production in vitro by PBMC can predict survival after radical surgery for colorectal cancer. © 2007 American Cancer Society.

- Objective. Peristomal bulging caused by hernia or prolapse is common in patients with a sigmoidostomy. It is not known whether and to what extent peristomal bulging influences various daily activities. The purpose of this study was to evaluate the effects of bulging by using a general and disease-specific health scale (Short Health Scale, SHS) and a stoma-specific quality of life (Stoma-QoL) questionnaire in patients with and without peristomal bulging. Material and methods. Seventy patients with sigmoidostomies were examined to identify peristomal bulging. The mean (SD) age was 71.7 (13.7) years and the patients had had their sigmoidostomies for a mean of 8.1 (7.9) years. Bulging was noticed in 46 patients (66%) while 24 had no bulging. Results. It was found that patients with bulging were at a disadvantage. In the SHS, patients with bulging reported significantly impaired QoL in 3 out of 4 scales regarding symptom load, worry and general sense of well-being. Also, in the Stoma-QoL questionnaire there was a significant difference between patients with and those without bulging. Conclusions. QoL evaluated with a general and disease-specific instrument (SHS) was significantly impaired in patients with bulging around a sigmoidostomy. The Stoma-QoL questionnaire showed a small but statistically significant difference between patients with and those without bulging but the clinical significance is uncertain. Further studies are required to evaluate the role of some of the individual items in the Stoma-QoL questionnaire. © 2008 Taylor & Francis.

- OBJECTIVE: The aim of this randomized multicenter trial was to assess the rate of symptomatic anastomotic leakage in patients operated on with low anterior resection for rectal cancer and who were intraoperatively randomized to a defunctioning stoma or not. SUMMARY BACKGROUND DATA: The introduction of total mesorectal excision surgery as the surgical technique of choice for carcinoma in the lower and mid rectum has led to decreased local recurrence and improved oncological results. Despite these advances, perioperative morbidity remains a major issue, and the most feared complication is symptomatic anastomotic leakage. The role of the defunctioning stoma in regard to anastomotic leakage is controversial and has not been assessed in any randomized trial of sufficient size. METHODS: From December 1999 to June 2005, a total of 234 patients were randomized to a defunctioning loop stoma or no loop stoma. Loop ileostomy or loop transverse colostomy was at the choice of the surgeon. Inclusion criteria for randomization were expected survival >6 months, informed consent, anastomosis ≤7 cm above the anal verge, negative air leakage test, intact anastomotic rings, and absence of major intraoperative adverse events. RESULTS: The overall rate of symptomatic leakage was 19.2% (45 of 234). Patients randomized to a defunctioning stoma (n = 116) had leakage in 10.3% (12 of 116) and those without stoma (n = 118) in 28.0% (33 of 118) (odds ratio = 3.4, 95% confidence interval, 1.6-6.9, P < 0.001). The need for urgent abdominal reoperation was 8.6% (10 of 116) in those randomized to stoma and 25.4% (30 of 118) in those without (P < 0.001). After a follow-up of median 42 months (range, 6-72 months), 13.8% (16 of 116) of the initially defunctioned patients still had a stoma of any kind, compared with 16.9% (20 of 118) those not defunctioned (not significant). The 30-day mortality after anterior resection was 0.4% (1 of 234) and after elective reversal a defunctioning stoma 0.9% (1 of 111). Median age was 68 years (range, 32-86 years), 45.3% (106 of 234) were females, 79.1% (185 of 234) had preoperative radiotherapy, the level of anastomosis was median 5 cm, and intraoperative blood loss 550 mL, without differences between the groups. CONCLUSION: Defunctioning loop stoma decreased the rate of symptomatic anastomotic leakage and is therefore recommended in low anterior resection for rectal cancer.

- Objective To establish the long term effects of obstetric anal sphincter rupture.Design Prospective observational study.Setting University hospital in Sweden.Population Eighty-two women from a prospective study from 1990 to compare anorectal function after third degree tear.Methods Women completed a structured questionnaire, underwent a clinical examination and anorectal manometry, endoanal ultrasound (EAUSG) with perineal body measurement.Main outcome measures Symptoms of anal incontinence, sexual symptoms, anal manometry scores and evidence of sphincter damage on EAUSG.Results Five women had undergone secondary repair and three were lost to follow up. Fifty-one women (80%) completed the questionnaire. Twenty-six out of 46 (57%) of the original study group and 6/28 (20%) of the original controls were examined. Incontinence to flatus and liquid stool was more severe in the study group than in controls. Flatus incontinence was significantly more pronounced among women with subsequent vaginal deliveries. Mean maximal anal squeeze pressures were 69 mmHg in the partial rupture group and 42 mmHg in the complete rupture group (P= 0.04). Study group women with signs of internal sphincter injury reported more pronounced faecal incontinence and had lower anal resting pressures (24 mmHg) than those with intact internal sphincters (40 mmHg) (P= 0.01). Perineal body thickness of less than 10 mm was associated with incontinence for flatus and liquid stools, less lubrication during sex and lower anal squeeze pressures (58 mmHg vs 89 mmHg, P= 0.04).Conclusions Subjective and objective anal function after anal sphincter injury deteriorates further over time and with subsequent vaginal deliveries. Thin perineal body and internal sphincter injury seem to be important for continence and anal pressure.
