Abstract: Objective To analyze the effect of endoscopic stricturotomy of anastomotic stenosis in patients with colorectal cancer and the complications of short-term closure of temporary stoma. Methods Clinical data of 7 colorectal cancer patients with postoperative anastomotic stricture underwent stoma closure after endoscopic stricturotomy in less than 2 weeks at The Sixth Affiliated Hospital of Sun Yat-sen University between January 2014 and December 2016 were retrospectively collected. The short-term and long-term effects of endoscopic stricturotomy and the incidence of surgical complications were analyzed after stoma closure. Results The endoscopic pass rate of 7 patients after endoscopic stricturotomy was 100%. All the cases underwent stoma closure after endoscopic stricturotomy in less than 2 weeks （6.6±2.9 days）. No complication was recorded after stoma closure. 2 cases accepted endoscopic intervention due to stricture recurrence. The long-term efficient rate was 71.4% with 30.2±10.8 months follow up. Conclusion Endoscopic stricturotomy in the treatment of postoperative anastomotic stricture of colorectal cancer is effective. Stoma closure after stricturotomy with short interval is safe.
