Adverse Events in Endoscopic Retrograde Cholangiopancreticography for Choledoccolithiasis: A Holistic Perspective

İngilizce (OpenAlex)

Background and aims In this study, we aimed to investigate the frequency of adverse events (AEs) in patients undergoing endoscopic retrograde cholangiopancreticography (ERCP) for choledocholithiasis and the independent risk factors that may cause these conditions. We planned to evaluate all AEs including cardiopulmonary complications and the risk factors that may affect them holistically. Methods This study was designed as a retrospective cohort study conducted at a single tertiary center's gastroenterology clinic. The study included patients with naive papillae and undergoing ERCP for choledocholithiasis between May 2019 and June 2022. Risk factors that may lead to AEs were analyzed in terms of both patient-related factors and procedure-related factors. Patients with and without AEs after ERCP were compared. Results This study included 812 patients who underwent ERCP for choledocholithiasis. AE occurred in 149 (18.3%) of patients, and the most common complication was pancreatitis (n=112, 13.8%). In regression analysis, of the patient- and procedure-related factors, only difficult cannulation was a significant independent risk factor for AEs (odds ratio=3.85, 95% CI: 1.102-13.498, p=0.035). Conclusion This study showed that, of patient- and procedure-related factors, only difficult cannulation is an independent risk factor for ERCP-related AEs.
