Background: Anastomotic leakage (AL) is a major complication after anterior resection. However, its therapeutic strategies and technical risk factors have not been well established. Therefore, we endoscopically evaluated anastomotic regions after laparoscopic colorectal anastomosis using a double-stapling technique (DST) for determination of treatment and investigation of technical factors. Methods: In total, 191 consecutive patients underwent laparoscopic anterior resection with a DST from September 2008-January 2013. Anastomotic regions were endoscopically evaluated in patients suspected to have AL after surgery. Results: Anastomotic dehiscence was observed in 19 patients, and AL was diagnosed in 18 (9.3%). Of the 19 patients, 12 were treated by creation of an intestinal stoma and 7 were treated conservatively based on their clinical status and endoscopic findings. Twentythree dehiscences were observed among 19 anastomotic regions; all 23 were observed on the circular stapler anastomosis lines. Of these 23 dehiscences, 13 (56.5%) were located at the point at which the anastomosis lines of the circular and linear staplers overlapped, and 10 (43.5%) were located on the circumferential aspect between the overlapping points. Conclusions: Endoscopic evaluation of anastomotic regions is safe and useful for the determination of therapeutic strategies. The DST anastomotic technique itself may be closely related to the development of AL.
