Laparoscopic right upper transversal hepatectomy: Strategies for right hepatic vein resection and reconstruction☆

Objective: The right upper transversal hepatectomy (RUTH) is considered a complex technique of parenchymalsparing hepatectomies. The intraoperative management of the right hepatic vein (RHV) is still controversial because it may cause obstruction of outflow in the remnant hepatic segment. The aim of this study is to present our experience of laparoscopic RUTH and the strategy of RHV resection and reconstruction in different settings. Methods: Five patients who underwent laparoscopic RUTH for liver tumor were enrolled retrospectively. Clinical and pathological features of the patients, peri-operative treatment, as well as short- and long-term outcomes were collected for analysis. Results: Laparoscopic RUTH was successfully performed in all five patients. Two individuals underwent RUTH while preserving RHV. Among the remaining patients who underwent RUTH with RHV resection, one patient underwent RHV reconstruction but the others did not. Immediate or long-term venous related complications did not occurred in a median follow-up period of nine months. Conclusions: Laparoscopic RUTH surgery for tumors in the right upper region of the liver is safe and feasible. The strategic workflow we proposed for the resection and reconstruction of the RHV offers a reliable method for preserving liver parenchyma and reducing the risk of postoperative liver failure.
