The intentional oblique transection double stapling technique in anterior resection for rectal cancer

Abstract

The double stapling technique (DST) is an intestinal reconstruction technique that has been widely adopted in anterior resection (AR) for rectal cancer. However, anastomotic leakage (AL) after the operation remains a major concern for colorectal surgeons. The sharp-angled corner of the remnant rectum that is often created by the ordinary DST can be a risk factor for AL. We have developed a new method of performing intentional oblique transection DST (IOT-DST). Using this technique, the anal side of the rectum is intentionally obliquely transected with linear staplers, and the area of the sharp-angled edge is totally punched out with a circular stapler. Between September 2015 and March 2016, we used the IOT-DST technique in the treatment of 15 consecutive rectal cancer patients and experienced no anastomosis-related complications, including leakage and stenosis. IOT-DST is easy to use and less stressful to perform than other techniques. IOT-DST has the potential to become the standard technique for AR in rectal cancer surgery.
