Application of the left side hepatic parenchymal transection‑first approach in laparoscopic central tumor anatomical hepatectomy

Acting as a difficult and high risk procedure in the operation, laparoscopic central tumor anatomical hepatectomy possesses various technical points that shall be noted in the process of application. The choice of laparoscopic approach has been recognized to be one of the key technical links for this technique. According to the anatomical characteristics of the middle lobe of liver and "Easy first" strategy, the authors summarize the laparoscopic central tumor anatomical hepatectomy technology with left side hepatic parenchymal transection‑first approach. The left side hepatic parenchymal transection‑first approach is found to be simple, fast, safe and effective in operation, which overcomes the challenges of complicated target Glisson pedicle operation and high technical risk of laparoscopic anatomical hepatectomy. The approach also better complies with the "no‑touch" principle for malignant tumors. Significantly, it exhibits clinical application value in laparoscopic central tumor anatomical hepatectomy.
