New Anastomosis Technique to Prevent Anastomotic Leakage in Laparoscopic Anterior Resection for Rectal Cancer, Especially Upper Rectal Cancer

摘要

BACKGROUND/AIM:Anastomotic leakage (AL) is a major problem in rectal cancer surgery. To prevent AL, we developed a side-to-side anastomosis technique using a circular stapler and termed it the circular side stapling technique (CST). We herein report the method and outcome of the CST.PATIENTS AND METHODS:In this study, we analyzed 154 patients with stage 0 to III rectal cancer who underwent curative laparoscopic low anterior resection. Perioperative factors and complications were compared between the CST and usual double stapling technique (DST).RESULTS:The CST was performed in 110 of the 154 patients. When comparing the outcomes of patients with upper rectal cancer. AL occurred in no patients in the CST group and in three patients in the DST group (p=0.011). The CST prevented AL in all patients with upper rectal cancer.CONCLUSION:The CST is a safe and useful procedure in laparoscopic anterior resection. This technique can prevent AL, especially in patients with upper rectal cancer.Copyright? 2020, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.
