Background: Anastomotic leakage during laparoscopic low anterior resection (Lap-LAR) for rectal cancer remains challenging for colorectal surgeons. Firing linear staplers multiple times has been reported as a risk factor for iatro-genic anastomotic leakage. Our institute usually performs rectal transection using 2 planned stapler fires followed by anastomosis with the double-stapling technique. Methods: Between November 2009 and September 2016, a total of 272 consecutive patients underwent Lap-LAR with double-stapling anastomosis for rectal cancer. We inserted a linear 45-mm stapler cartridge from a port in the lower right quadrant of the abdomen. The first transection was made up to three-quarters of the rectal wall, and the remaining rectum was completely resected using a second stapler. During this procedure, the intersection of the 2 staple lines, which might otherwise cause anastomotic leakage, was located in the center of the stump of the distal rectum, so the intersection at the rectal stump was able to be easily removed using a circular stapler. Results: None of our patients were converted to open surgery. Among the 272 Lap-LAR procedures for which use of 2 stapler fires was planned, 3 fires occurred in error only once (0.4%). Rectovaginal fistula and anastomotic leakage occurred in 1 patient (0.4%) and 9 patients (3.3%), respectively, and 49 (18.0%) patients required protective diverting stoma. Conclusion: Rectal transection with 2 planned stapler fires appears safe, practical, and straightforward to stan-dardize, and reduces the need for multiple linear fires and the incidence of anastomotic leakage.
