A stent-based diverting technique after low anterior resection of rectal cancer: our preliminary experience

Abstract

Anastomotic leakage (AL) is a severe complication of rectal cancer low anterior resection (LAR). Ileostomy, the most common method to reduce the severity of AL, is associated with the risk of permanent stoma and an additional operation for stoma reversal. This purpose of this study is to develop a novel protective technique called the stent-based diverting technique (SDT) to protect the anastomosis following LAR. From March 2020 to December 2020, thirty-four patients treated with LAR followed by SDT were enrolled prospectively at Sir Run Run Shaw Hospital. Demographic characteristics, laboratory test results, surgical outcomes, and oncological features were recorded. Overall, the median period of stent degradation was 21 (18-24) days. One patient (2.9%) had anastomotic leakage, and another patient (2.9%) had intestinal obstruction, while no other complications (e.g., intestinal volvulus, perforation, fistula) were observed in this study. The unique SDT may be a novel approach to prevent anastomotic leakage following low anterior resection of rectal cancer.
