RESUMO
Objective Comparing the efficacy of endoscopic balloon dilatation and endoscopic stricteroto-my for postoperative anastomotic stenosis of colorectal cancer. Methods Retrospectively analyzed the clinical data of patients with postoperative anastomotic stenosis of colorectal cancer that underwent anastomotic dilatation from 2013 to 2016,and analyzed the anastomotic stenosis before and after treatment,and compared the efficacy of the two groups of dilatation methods. Results There was no statistically significant difference between the two groups in baseline characteristics. Balloon dilatation was effective in 3 cases(23.1%),ineffective in 10 cases(76.9%). 7 cases(63.6%)were effective in the stricterotomy group,4 cases(36.4%)were ineffective,the difference was statistically significant(P=0.045).Two groups of patients were not bleeding after surgery,infection and perfora-tion and other complications. Conclusion Endoscopic stricterotomy of postoperative anastomotic stenosis of colorectal cancer is more effective than conventional endoscopic balloon dilatation
