Short article: Successful faecal coliform sensitivity-based oral ertapenem therapy for chronic antibiotic-refractory pouchitis: a case series.

Pouchitis is a common complication of restorative proctocolectomy for ulcerative colitis, and a proportion of patients develop a refractory course. The treatment of chronic antibiotic-refractory pouchitis (CARP) is challenging, and treatment failure is often a cause of pouch excision. We report on a series of three patients with CARP who were treated with oral ertapenem following faecal coliform sensitivity testing. There was an improvement in the pouchitis disease activity index in all three patients [pretreatment pouch disease activity index, median 13 (range: 10-14); post-treatment pouch disease activity index, median 1 (range: 1-3)]. Identification of faecal coliform sensitivity and treatment with oral ertapenem might be helpful in patients with CARP.

Randomized trial of laparoscopic-assisted resection of colorectal carcinoma: 3-year results of the UK MRC CLASICC Trial Group.

PURPOSE: The aim of the current study is to report the long-term outcomes after laparoscopic-assisted surgery compared with conventional open surgery within the context of the UK MRC CLASICC trial. Results from randomized trials have indicated that laparoscopic surgery for colon cancer is as effective as open surgery in the short term. Few data are available on rectal cancer, and long-term data on survival and recurrence are now required. METHODS: The United Kingdom Medical Research Council Conventional versus Laparoscopic-Assisted Surgery in Colorectal Cancer (UK MRC CLASICC; clinical trials number ISRCTN 74883561) trial study comparing conventional versus laparoscopic-assisted surgery in patients with cancer of the colon and rectum. The randomization ratio was 2:1 in favor of laparoscopic surgery. Long-term outcomes (3-year overall survival [OS], disease-free survival [DFS], local recurrence, and quality of life [QoL]) have now been determined on an intention-to-treat basis. RESULTS: Seven hundred ninety-four patients were recruited (526 laparoscopic and 268 open). Overall, there were no differences in the long-term outcomes. The differences in survival rates were OS of 1.8% (95% CI, -5.2% to 8.8%; P = .55), DFS of -1.4% (95% CI, -9.5% to 6.7%; P = .70), local recurrence of -0.8% (95% CI, -5.7% to 4.2%; P = .76), and QoL (P > .01 for all scales). Higher positivity of the circumferential resection margin was reported after laparoscopic anterior resection (AR), but it did not translate into an increased incidence of local recurrence. CONCLUSION: Successful laparoscopic-assisted surgery for colon cancer is as effective as open surgery in terms of oncological outcomes and preservation of QoL. Long-term outcomes for patients with rectal cancer were similar in those undergoing abdominoperineal resection and AR, and support the continued use of laparoscopic surgery in these patients.

Short-term endpoints of conventional versus laparoscopic-assisted surgery in patients with colorectal cancer (MRC CLASICC trial): multicentre, randomised controlled trial.

BACKGROUND: Laparoscopic-assisted surgery for colorectal cancer has been widely adopted without data from large-scale randomised trials to support its use. We compared short-term endpoints of conventional versus laparoscopic-assisted surgery in patients with colorectal cancer to predict long-term outcomes. METHODS: Between July, 1996, and July, 2002, we undertook a multicentre, randomised clinical trial in 794 patients with colorectal cancer from 27 UK centres. Patients were allocated to receive laparoscopic-assisted (n=526) or open surgery (n=268). Primary short-term endpoints were positivity rates of circumferential and longitudinal resection margins, proportion of Dukes' C2 tumours, and in-hospital mortality. Analysis was by intention to treat. This trial has been assigned the International Standard Randomised Controlled Trial Number ISRCTN74883561. FINDINGS: Six patients (two [open], four [laparoscopic]) had no surgery, and 23 had missing surgical data (nine, 14). 253 and 484 patients actually received open and laparoscopic-assisted treatment, respectively. 143 (29%) patients underwent conversion from laparoscopic to open surgery. Proportion of Dukes' C2 tumours did not differ between treatments (18 [7%] patients, open vs 34 [6%], laparoscopic; difference -0.3%, 95% CI -3.9 to 3.4%, p=0.89), and neither did in-hospital mortality (13 [5%] vs 21 [4%]; -0.9%, -3.9 to 2.2%, p=0.57). Apart from patients undergoing laparoscopic anterior resection for rectal cancer, rates of positive resection margins were similar between treatment groups. Patients with converted treatment had raised complication rates. INTERPRETATION: Laparoscopic-assisted surgery for cancer of the colon is as effective as open surgery in the short term and is likely to produce similar long-term outcomes. However, impaired short-term outcomes after laparoscopic-assisted anterior resection for cancer of the rectum do not yet justify its routine use.
