    Abstract:
    OBJECTIVE: Recurrent attacks after acute gallstone pancreatitis (GSP) are substantial problems, together with associated morbidity and mortality. The recommended therapies for recurrent attacks are cholecystectomy and endoscopic sphincterotomy (EST). This study aimed to evaluate the long-term results of cholecystectomy and EST after clinical improvement of GSP. METHODS: A consecutive series of patients who were admitted with GSP from January 2003 to December 2014 were analyzed. Patients were categorized into three treatment subgroups: cholecystectomy (n = 53), EST (n = 51) and conservative care (n = 67). RESULTS: A total of 171 patients were enrolled. The mean follow-up period was 58 months (range 6-125 months). The pancreatitis-induced in-hospital mortality rate was 1.5%. The cholecystectomy and EST groups had a significantly lower frequency of recurrent pancreatitis than the conservative care group (P < 0.01). For recurrent pancreatitis, there was no significant difference between the cholecystectomy with and without EST subgroups. With respect to total recurrent biliary events, the cholecystectomy group was superior to the EST only group (P < 0.01). In patients receiving definitive treatment (cholecystectomy with or without EST), the presence of common bile duct (CBD) stone was an independent risk factor for recurrent biliary events (P < 0.01). CONCLUSIONS: In the long-term follow up of GSP, cholecystectomy can offer better protection against recurrent biliary events than EST only. The presence of CBD stones at time of definitive therapy might be a risk factor for recurrent biliary events.
