Background: Laparoscopic rectal cancer surgery involving rectal division with intracorporeal stapling devices is technically difficult. This study aimed to identify risk factors for anastomotic leakage associated with laparoscopic anterior resection for rectal cancer.
Methods: We studied 363 patients who underwent laparoscopic anterior resection with intracorporeal rectal transection and double-stapling technique (DST) anastomosis for rectal cancer between July 2005 and February 2010. Twenty-two independent clinical variables were examined by univariate and multivariate analyses. The outcome of interest was clinical anastomotic leakage.
Results: Anastomotic leakage was identified in 13 (3.6%) patients. Multivariate analysis identified middle/lower rectal cancer (odds ratio, 9.446) and lack of pelvic drain (odds ratio, 3.814) as independent predictive factors for anastomotic leakage. The number of cartridges used for rectal division had no significant impact on anastomotic leakage.
Conclusions: Laparoscopic anterior resection involving intracorporeal rectal transection and DST anastomosis is safe if performed using an appropriate technique.
