Endoscopic repair of duodenal perforations, a scoping review

Abstract

Abstract Background There is a discrepancy in the surgical and endoscopic literature for managing duodenal perforations. Although often managed conservatively, surgical repair is the standard treatment for duodenal perforations. This contrasts with the gastroenterology literature, which now recommends endoscopic repair of duodenal perforations, which are more frequently iatrogenic from the growing field of advanced endoscopic procedures. This study aims to provide a scoping review to summarize the current literature content and quality on endoscopic repair of duodenal perforations. Methods The protocol for performing this scoping review was outlined by the Joanna Briggs Institute. All studies that reported primary outcomes of patients who had undergone endoscopic repair of duodenal perforations before February 2022, regardless of perforation etiology or repair type were reviewed, with studies after 1999 meeting inclusion criteria. The study excluded articles that did not report clinical outcomes of endoscopic repair, articles that did not describe where in the gastrointestinal tract the endoscopic repair occurred, pediatric patients, and animal studies. Results 7606 abstracts were screened, with 474 full articles reviewed and 152 studies met inclusion criteria. 560 patients had duodenal perforations repaired endoscopically, with a technical success rate of 90.4% and a survival rate of 86.7%. Most of these perforations (74.5%) were iatrogenic from endoscopic procedures or surgery. Only one randomized control trial (RCT) was found, and 53% of studies were case reports. Conclusion These results suggest that endoscopic repair could emerge as a viable first-line treatment for duodenal perforation and highlight the need for more high-quality research in this topic.
