Indocyanine Green Perfusion Imaging-Guided Laparoscopic Pancreaticoduodenectomy: Potential Application in Retroperitoneal Margin Dissection

During laparoscopic pancreaticoduodenectomy (LPD), dissecting uncinate process from the superior mesenteric artery (SMA) will determine one of the important surgical margins (retroperitoneal margin) for predicting oncological outcomes and the quality of LPD. However, clear identification of the division line for retroperitoneal margin is not easy as the uncinate process of the pancreas is anatomically very close to SMA and intermingled with the...
