Endoluminal management of colon perforations during advanced endoscopic procedures

Background: Advanced endoscopic procedures are gaining attraction despite a steep learning curve, need for high dexterity, and potential complications. Colonic perforation is the most concerning adverse event during advanced endoscopic procedures. This study presents our experience on endoluminal manage-ment of iatrogenic colonic perforations.Methods: Patients who underwent advanced endoscopic procedures at a quaternary center from 2016 to 2021 were identified. Patients who had colonic perforations during advanced procedures and treated with endoscopic closure/clipping were included. Retrospective chart review was performed. Figures represent frequency (proportion) or median (interquartile range/range). Results: There were 22 (2.3%) immediate colonic perforations treated with endoscopic clipping out of 964 advanced endoscopic resections. The median age was 64 (interquartile range = 57-71) years and 50% of the patients were female; 16 (73%) resections were proximal to the splenic flexure. Median polyp size was 36 (20-55) mm. Closure was performed with endoscopic clips in 18 (82%) patients, and over -the-scope clips in 4 patients. Median hospital stay was 0.8 (0-4) days, and 13 (59%) patients were discharged the same day; 2 patients were admitted to the emergency department <= 24 hours of pro-cedure. They underwent subsequent laparoscopic suture repair the same day. No one had segmental colon resection, and there were no complications within postoperative 30 days. Pathology revealed 9 (41%) tubular adenomas, 7 (32%) tubulovillous adenomas, 6 (27%) sessile serrated lesions, and no adenocarcinoma. No recurrence was observed with median follow-up of 24 months (range = 0-90 months).Conclusion: Endoscopic management is an effective treatment approach for the management of iatro-genic colonic perforations.

Automated summary

This study presents the authors' experience in managing iatrogenic colonic perforations through endoscopic closure. Among 964 advanced endoscopic resections, 22 cases (2.3%) experienced colonic perforation, with 18 cases treated with endoscopic clipping. No complications were observed postoperatively, and there was no recurrence during the follow-up period.
