    Abstract:
    BACKGROUND: Early cholecystectomy (EC) is recommended in patients with acute biliary pancreatitis (ABP). In real-life practice, cholecystectomy is frequently deferred due to various reasons and delayed cholecystectomy (DC) is performed instead. Endoscopic sphincterotomy (ES) is an alternative to prevent recurrent pancreatitis, however other gallstone-related complications (GCs) may still develop. We aimed to determine the impact of ES on future GCs in patients with non-severe acute biliary pancreatitis whose cholecystectomy was deferred or not performed. METHODS: During 2006-2016, we included patients with non-severe ABP while those with severe pancreatitis and concurrent cholangitis were excluded. GC events were compared between those who had DC with ES and those who had DC without ES. A similar comparison was made in patients with and without ES who did not receive cholecystectomy. RESULTS: Of 266 patients with ABP, non-severe ABP was identified in 146. Only 16 (11%) had EC. Of patients with non-severe ABP who underwent DC (n = 88), recurrent ABP in the ES group was lower than those from the non-ES group (2% vs. 17%; p = 0.01). Acute cholecystitis was found in 0%, 6% and 10% of patients with EC, DC and those without cholecystectomy (p = 0.39). Of those who did not undergo cholecystectomy (n = 42), recurrent ABP in the ES group was still lower than the non-ES group (4% vs. 36%; p = 0.006). ES related complications were mild pancreatitis (4%) and post sphincterotomy bleeding (5%). CONCLUSIONS: In patient with non-severe ABP, ES is an alternative to reduce recurrent ABP, however without EC, future cholecystitis may still develop.
