Background and AimsCurrent guidelines recommend cholecystectomy in patients with acute biliary pancreatitis (ABP) to prevent recurrence. Some studies suggest that a significant portion of patients with idiopathic acute pancreatitis (IAP) results from occult biliary disease and cholecystectomy, after an episode of IAP, reduces the risk of recurrent pancreatitis. However, in these studies, the work-up for potential biliary cause is not extensive and do not include endoscopic ultrasound (EUS), which can detect a biliary disease up to one-third of patients with IAP. In this study, we aimed to ascertain whether cholecystectomy can prevent pancreatitis recurrence in patients with ABP and IAP.MethodsAdult patients (over 18 years) with first episode of acute pancreatitis (AP) who admitted to inpatient clinic between January 1, 2015 and December 31, 2021 at a tertiary referral center were retrospectively reviewed. Medical records were scrutinized and relevant data extracted. In addition, a questionnaire either by mail or telephone was used. Patients with biliary and idiopathic AP were included in the analysis. Patients with chronic pancreatitis, previous pancreatic surgery, pancreatic cancer, and other etiologies were excluded. Primary outcome was recurrence rate. The diagnosis of IAP was confirmed by exclusion of all known etiological factors for AP using extensive work-up, including EUS and/or magnetic resonance cholangiopancreatography (MRCP).ResultsA total of 500 patients with first episode of AP (300 patients with ABP and 200 patients with IAP) were identified. The mean age was 58 years and 267 women, 233 men. The patients were divided into three different groups: Group 1; patients who had their first pancreatitis attack after cholecystectomy, Group 2; patients who had their gallbladder in situ during the first attack and followed by cholecystectomy and Group 3; patients who had their gallbladder in situ during the first attack but did not have cholecystectomy. The number of patients with recurrence after the first episode of AP were not statistically different in whole study group (25%, 19% and 15%, respectively, P = 0.176). In the subgroup of patients with ABP, the recurrence was higher in group 1 as compared with group 2 and 3 (39%, 19% and 14%, respectively, P = 0.018). On the other hand, in the subgroup of patients with IAP, there was no significant difference among the groups in terms of recurrence (15%, 18%, and 17%, respectively, P = 0.999). When patients with in situ gallbladder during their first attack were compared according to their cholecystectomy history (group 2 vs. group 3), no significant difference was found in neither the ABP nor the IAP subgroups (19% vs 14% and 18% vs. 17%, respectively, P > 0.05). In addition, the effect of endoscopic retrograde cholangiopancreatography (ERCP) on recurrence of pancreatitis was evaluated. In subgroup of ABP, ERCP was effective for reducing the recurrence in group 2 (P = 0.008), while it was not found statistically significant in group 1 and 3. In subgroup of IAP, it ERCP did not reduce the recurrence in any of the groups.ConclusionsIn ABP, the recurrence is high in patients who have their first pancreatitis attack after cholecystectomy. Cholecystectomy alone is not effective preventing recurrence in patients with gallbladder in situ during the first episode; however, the risk can be decreased with adding ERCP to cholecystectomy. On the other hand, cholecystectomy is not effective in reducing the recurrence in patients with IAP.Key Words: Acute biliary pancreatitis; Idiopathic acute pancreatitis; Cholecystectomy.References:1.
