Anastomotic leak (AL) represents a dreaded complication following colorectal surgery, with a prevalence of 1-19 per cent. There remains a lack of consensus regarding factors that may predispose to AL and the relative risks associated with them. The objective was to perform a systematic review of the literature, focusing on the role of preoperative, intraoperative and postoperative factors in the development of colorectal ALs.

The role of a defunctioning stoma in patients undergoing low anterior resection for rectal cancer is still the subject of controversy. Recent studies suggest reduced morbidity after low anterior rectal resection with a defunctioning stoma. Retrospective and prospective studies published between 1966 and 2007 were systematically reviewed. Randomized controlled trials (RCTs) comparing anterior resections with or without defunctioning stoma were included in a meta-analysis. The pooled estimates of clinically relevant anastomotic leakages and of reoperations were analyzed using a random effects model (odds ratio and 95% confidence interval, CI). Relevant retrospective single (n = 18) and multicenter (n = 9) studies were identified and included in the systematic review. Analysis of incoherent data of the leakage rates in these nonrandomized studies demonstrated that a defunctioning stoma did not influence the occurrence of anastomotic failure but seemed to ameliorate the consequences of the leak. Four RCTs were included in the meta-analysis. The odds ratio for clinically relevant anastomotic leakage was 0.32 (95% CI 0.17-0.59), revealing a statistically significant benefit conferred through a defunctioning stoma (Z = 3.65, P = 0.0003). The odds ratio for reoperation because of leakage-caused complications was 0.27 (95% CI 0.14-0.51), with significantly fewer reoperations in patients with a defunctioning stoma (Z = 3.95, P < 0.0001). Overall mortality rates were comparable regardless of the presence of a defunctioning stoma. A defunctioning stoma reduces the rate of clinically relevant anastomotic leakages and is thus recommended in surgery for low rectal cancers.

The dramatic clinical consequences of anastomotic leakage in gastrointestinal surgery can be reduced by a diverting stoma or drainage of the peri-anastomotic area. Currently, the surgeons' clinical judgement is of major importance in decision making, but reliable data of the diagnostic accuracy are lacking. In this prospective clinical study, the surgeons' predictive accuracy for anastomotic leakage was evaluated. In 191 patients undergoing colorectal resection with anastomosis, the risk for anastomotic leakage was determined by the surgeon on the basis of a visual analogue scale (VAS). This risk assessment was compared to the actual occurrence of anastomotic leakage post-operatively. A total of 26 (13.6%) patients showed anastomotic leakage. The surgeons' median predicted leakage rate was 7.1% in anastomoses >15 cm from the anal verge and 9.5%
