Abstract

Background: Autoimmune pancreatitis (AIP) is a rare subtype of chronic pancreatitis that may mimic adenocarcinoma of the pancreas. The aim of this study was to evaluate the short-term and long-term outcomes of pancreatectomy for patients with AIP. Methods: In this multi-institutional study, we identified all patients who underwent pancreatectomy for AIP from 1986 to 2011. AIP was confirmed by pathology review. Clinical presentation, operative details, and postoperative outcomes were analyzed. Results: Seventy-four patients (median age, 60 years; 69 % male) with AIP underwent pancreatectomy. The main indication for operation was concern for malignancy (n = 59, 80 %). No patients were found to have pancreatic adenocarcinoma on final pathology. Major complications occurred in ten (14 %) patients, with one perioperative death (1 %). Clinically relevant (grade B/C) pancreatic fistulae occurred in two patients. No patients required reoperation for AIP and 11 (17 %) patients developed recurrent AIP. Conclusion: Although we do not advocate pancreatectomy for AIP, strong suspicion of malignancy may require an operation in selected patients. For patients with AIP, pancreatectomy resulted in few pancreatic fistulae, a low rate of re-intervention, and a 17 % recurrence rate.
