Abstract

Background: Endoscopic retrograde cholangiopancreatography (ERCP)-related perforation is a rare and serious adverse event. The aim of our study was to evaluate the risk factors and management of ERCP-related perforation, and to further determine the predictive factors associated with perforation outcome.

Methods: A total of 27,018 ERCP procedures performed at the First Affiliated Hospital of Nanchang University (Nanchang, China) between January 2007 and March 2022 were included in the investigation of ERCP-related perforation. Medical records and endoscopic data were extracted to analyse the risk factors, management, and clinical outcome of ERCP-related perforation.

Results: Seventy-six patients (0.28%) were identified as having experienced perforation following ERCP. Advanced age, Billroth II anatomy, precut sphincterotomy, and papillary balloon dilatation were significantly associated with ERCP-related perforation. Most patients with perforation (=65) were recognized immediately during ERCP whereas 11 were recognized later on. The delay in recognition primarily resulted from stent migration (=9). In addition, 12 patients experienced poor clinical outcome including death or hospice discharge (=3), ICU admission for >3 days (=6), and prolonged hospital stay for >1 month due to perforation (=3). Cancer and systemic inflammatory response syndrome (SIRS) are associated with a higher risk of poor outcome.

Conclusions: Advanced age, Billroth II anatomy, precut sphincterotomy, and balloon dilation increase the risk of ERCP-related perforation whereas cancer and SIRS independently predicted poor clinical outcome.
