Repeated Minimally Invasive Pancreatectomy for Intraductal Papillary Mucinous Neoplasm in the Remnant Pancreas: A Case Report.

Objective: Unusual or unexpected effect of treatment Background: Minimally invasive pancreatectomy has become the standard practice for the management of benign and malignant pancreatic tumors. Techniques such as robotic and laparoscopic approaches are known to reduce morbidity by offering benefits such as less blood loss, reduced pain, shorter hospital stays, and quicker recovery times. The indication for repeated minimally invasive pancreatectomy for recurrent or de novo pancreatic neoplasm after primary pancreatic surgery remains debated. Case Report: A 50-year-old woman was admitted to our hospital with a diagnosis of an intraductal papillary mucinous neoplasm in the pancreatic head. In 2010, she underwent laparoscopic single-branch resection for a branch-type tumor in the pancreatic uncinate process. During a 5-year follow-up, a de novo intraductal papillary mucinous neoplasm was detected, showing gradual growth and the presence of a mural nodule over the next 7 years. The patient’s CEA level was elevated to 7.0 ng/mL. Considering the tumor’s progression and the appearance of a mural nodule, we recommended a robot-assisted Whipple procedure. The operation began with laparoscopic adhesiolysis. After detachment of the adhesions and remobilization of the duodenum using the Kocher maneuver, the operation continued with the Da Vinci surgical system. The postoperative period was uneventful, and the patient was discharged on postoperative day 20. Pathological examination revealed intraductal papillary mucinous carcinoma in situ with negative resection margins. Conclusions: This case verifies the safety and feasibility of performing a robotic Whipple procedure for a newly diagnosed pancreatic neoplasm in patients who have previously undergone minimally invasive pancreatic surgery.
