Abstract:
Objective:To investigate the strategy and feasibility of surgery for iatrogenic perforation of colorectum following colonoscopic examination or treatment.Methods:A retrospectively descriptive study was conducted. Twenty-one patients aged from 35 to 84 years old from the Department of General Surgery of the First Affiliated Hospital of Nanjing Medical University between Jan. 2015 and Dec. 2020 were enrolled in this study. There were 15 male and 6 female patients with a median age of 64 years.Observation indicators included patient demographics, including sex, age, comorbidity, abdominal surgical history; findings and outcomes of colonoscopy, including purpose of colonoscopy, time to the diagnosis of perforation; findings and outcomes of surgical treatment, including perforation site, perforation size, surgical methods, postoperative complications.Results:Eight patients were found with diagnostic colonoscopic perforation, 13 patients with therapeutic perforation (2 patients with endoscopic mucosal resection, 7 patients with endoscopic submucosal dissection and 4 patients with stent placement). Thirteen perforation occurred during the procedure of colonoscopy. Eleven patients with perforation occurred in the sigmoid colon, 3 in the ascending colon, 3 in the rectum, 2 in the descending colon, 1 in the cecum and 1 in the hepatic flexure. The perforation size ranged from 0.3 cm to 10.0 cm with a high likelihood of a bigger perforation occurred in diagnostic colonoscopy than therapeutic colonoscopy. Seven patients received primary surgical repair with 3 patients receiving diversion. Four patients received direct colostomy in the perforation site. Six patients received segmental colectomy or radical resection with primary anastomosis, among them 2 patients received defunctioning ileostomy. Four patients received resection with the Hartmann procedure. Nine patients were performed with laparoscopic surgery with 3 patients converted to open surgery. Six patients developed postoperative complications, including 1 bowel leakage, 2 wound infection, 1 wound infection accompanied with abdominal infection, 1 kidney infection. One patient with hepatic flexure perforation after stent placement died from septic shock after the Hartmann procedure.Conclusion:With proper indication, the performance of optimal surgical treatment will save lives of patients with colonoscopic perforation.
