BACKGROUND: Laparoscopic transection of the pancreatic neck with enucleation of intraductal papillary mucinous neoplasm (IPMN) in the uncinate process and pancreatic reconstruction represents a novel surgical approach for managing pancreatic intraductal papillary mucinous neoplasms. This technique may provide a new therapeutic option for patients with benign or low-grade malignant tumors in the pancreatic uncinate process. This study aimed to assess this procedure's short- and long-term clinical outcomes and delineate its technical operative details.
METHODS: For a 42-year-old man, branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) was diagnosed. Abdominal contrast-enhanced computed tomography (CT) showed an irregular cystic lesion in the cephalad portion of the pancreatic uncinate process, with no enhancement on post-contrast imaging. Abdominal MRI demonstrated the irregular cystic lesion (38 × 18 mm), showing suspected communication with the pancreatic duct. Endoscopic ultrasound (EUS) showed a multicystic lesion in the pancreatic uncinate process measuring up to 40 mm in maximum diameter, with heterogeneous wall thickness and well-defined margins. The patient subsequently underwent laparoscopic transection of the pancreatic neck with enucleation of IPMN in the uncinate process and pancreatic reconstruction.
RESULTS: The patient experienced a biochemical leak postoperatively, with a daily drainage volume of approximately 20 mL. The drainage volume gradually decreased, and the drain was removed on postoperative day 10, followed by hospital discharge. At this writing, follow-up evaluations have shown no complications such as steatorrhea, secondary diabetes, or dyspepsia. A contrast-enhanced CT scan of the entire abdomen showed no abnormalities. Morphologic and immunohistochemical analyses confirmed the diagnosis of IPMN with mild epithelial dysplasia.
CONCLUSION: Laparoscopic transection of the pancreatic neck with enucleation of IPMN in the uncinate process and pancreatic reconstruction represents a safe and effective surgical approach for managing pancreatic uncinate process IPMN.
