Total Pancreatectomy for Presumed Intraductal Papillary Mucinous Neoplasms: A Multicentric Study of the French Surgical Association (AFC)

imageObjective: The aim of the current study was to assess the short and long-term outcome of total pancreatectomy (TP) for IPMN based on the largest series to date. Background: Literature data are scarce regarding TP for IPMN, though increasingly performed in this setting. Methods: Data of 888 IPMN patients operated between 2004 and 2013 were collected in a multicentric retrospective AFC database. Ninety-three patients (10.5%) who had TP entered this study. Patient demographics, indications, intraoperative data, 3-month morbi-mortality (Clavien), and long-term outcome were analyzed. Results: Most patients had mixed type IPMN (59%) and underwent upfront (56%) or intraoperatively-decided (33%) TP. Morbidity and mortality rates were 47.3% and 4.3%, respectively, with no lethal hypoglycemia; morbidity was higher for intraoperatively-decided TP. Misdiagnoses were frequent regarding main pancreatic duct involvement (12%), invasiveness (33%), or mural nodules (50%), resulting in 12 TPs (13%) performed for asymptomatic IPMN showing only low/moderate dysplasia (LMD). On histopathological examination, there were 54 (58%) invasive IPMN (mostly pT3/T4 (76%), N+ (60%), R0 (75%)), with a significantly worse 5-year survival (21.2%) compared to noninvasive group (85.7%; P
