Background: Anastomotic leaks after low anterior resection for rectal cancer remain the most feared complication. The aim of our study was to investigate whether the use of a transanal tube could reduce the leakage rate after this surgical procedure. Methods: This is a retrospective analysis of a single-institution experience. The study includes 66 patients who underwent low anterior resection for rectal cancer without stoma creation between January 2008 and June 2013. Patients were divided into two groups, i.e. those with a transanal drainage tube (TT; n = 9) and those without tube (NTT; n = 57), and evaluated for clinically evident anastomotic leakage and postoperative complications. Results: The postoperative anastomotic leakage appeared in 5 patients (9%) in the NTT group while no single case was observed within the TT group. Despite the disadvantageous background in the TT group (a transanal stent was used in the most high-risk patients), these patients had no postoperative complications. In the NTT group, 23% had some kind of postoperative complications, and 5% died. The difference between the two groups is not significant. Conclusions: Our study showed that the use of a transanal tube in low anterior resection for rectal cancer could potentially be a simple and effective method of reducing anastomotic leakage. In order to prove our observations, larger prospective randomized studies should be performed.
