[Application of intestinal stent in prevention of anastomotic leakage after rectal cancer operation].

To observe preventive effect of intestinal stent against anastomotic leakage after rectal cancer operation. A retrospective cohort study was carried out. Clinical data of 107 patients with low rectal cancer undergoing laparoscopic radical resection from January 2015 to August 2019 were retrospectively analyzed. Intestinal stent was placed intraoperatively in 48 cases and was not placed in 59 cases. Postoperative Wexner score for anal function and incidence of anastomotic leakage were compared between patients with and without intstinal stent. There was no significant differences in age, distance between tumor and the anal verge, operative time and postoperative Wexner score for anal function between the two groups (all >0.05). After a month of follow-up, the incidence of anastomotic leakage was 16.9% (10/59) in the non-stent group, while no anastomotic leakage was found in the stent group (=0.002). Placement of intestinal stent can effectively prevent anastomotic leakage after low rectal cancer surgery.
