Robotic pancreatectomy for intraductal papillary mucinous neoplasm of the pancreas: A large‐scale study

Background Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a mucin‐producing tumor that develops from the epithelial lining of the main pancreatic duct or branch pancreatic ducts. Here, we assessed the feasibility and safety of various robotic pancreatectomy approaches to treating IPMN, and short‐ and long‐term outcomes of robotic IPMN resection. Methods Data from patients who underwent robotic pancreatectomy for IPMN between 2012 and 2019 at our hospital were retrospectively analyzed. The survival outcomes for patients were compared using the Kaplan‐Meier method and Cox regression analysis. Results Of the 174 patients who underwent robotic pancreatectomy, 120 and 54 patients had benign or malignant tumors, respectively. Patients with malignant IPMN had lost more weight in the 6 months prior to surgery (P = .008), and a higher serum level of CA19‐9 (P
