Abstract

Laparoscopic total pancreatectomy (LTP) is technically challenging and infrequently documented in the literature. In this paper, we present a new approach for performing fully LTP, a pancreatic tail-first approach with a counterclockwise technique, to accomplish total mesopancreas dissection and standard lymphadenectomy en bloc. Firstly, the tail and body of the pancreas without the spleen were dissected retrogradely, starting from the lower border of the body of pancreas and then from left to right. After that, a counterclockwise dissection of the tail and body of the pancreas was performed. The splenic artery and vein were divided at the terminal end of the pancreatic tail. The spleen was preserved. The entire body and tail of the pancreas were then pulled to the right side. This maneuver facilitated the isolation and dissection of arteries in the retropancreatic region more easily via laparoscopy, including the splenic artery, gastroduodenal artery, and supporting superior mesenteric artery first-approach. It also enabled total mesopancreas dissection. The inferior pancreaticoduodenal artery was resected last during this phase. The remainder of the dissection was like that of a laparoscopic pancreaticoduodenectomy with total mesopancreas dissection, involving two laparoscopic manual anastomoses. The operative time was 490 minutes and the total blood loss was 100 mL. Pathology revealed a low-grade intraductal papillary mucinous neoplasm extending from the head to the tail of the pancreas.
