Robotic Pancreaticoduodenectomy Using the <i>hinotori</i> Surgical System with Extended Resection for Type II Circumportal Pancreas: A Case Report.

ABSTRACT:

Introduction

Circumportal pancreas (CP) is a rare congenital anomaly in which pancreatic parenchyma encases the portal vein. CP poses significant technical challenges during pancreatic surgery, particularly in safely isolating the pancreas from the portal vein, determining the optimal transection line, and managing the pancreatic stump. This report describes a case of CP identified intraoperatively during a robotic pancreaticoduodenectomy (RPD), in which an extended resection was required to achieve a single pancreatic duct for safe reconstruction.

Case presentation

A 77-year-old man diagnosed with distal bile duct cancer underwent RPD using the hinotori Surgical Robot System (Medicaroid, Hyogo, Japan). Preoperative contrast-enhanced CT demonstrated circumferential en
