Overview
The study, entitled "RCT study of laparoscopic middle hepatic venous guidance versus conventional ananatomical hemihepatectomy", was designed to compare the efficacy of two different ananatomical hemihepatectomy procedures under laparoscopy.
Description
Backgroud & Aim:Hepatectomy is the main way to treat all kinds of liver surgical diseases, which can be divided into anatomic hepatectomy and non-anatomic hepatectomy.Among them, anatomic hepatectomy is suitable for primary liver cancer, hepatolithiasis and other benign and malignant diseases;It can be divided into hepatic venous guidance and non-hepatic venous guidance hepatectomy (traditional ananatomical hepatectomy).The aim of this study was to observe and compare the perioperative period and follow-up results of the two different laparoscopic surgical resection methods, and to provide high-level evidence-based medicine evidence for the selection of surgical methods for laparoscopic anatomical hemihepatectomy.

- patients with severe liver cirrhosis, portal hypertension and lesions invading liver porta;
- patients with other treatment methods such as radio frequency ablation in addition to dissecting hepatectomy;
