Core Tip

Core Tip: Although en bloc dissection of hepatic hilum lymph nodes has many advantages, the feasibility and safety of this approach for laparoscopic pancreaticoduodenectomy (LPD) requires further clinical investigation. We showed that the emerging technique of "five steps four quadrants" modularized en bloc dissection of hepatic hilum lymph nodes is safe and feasible for LPD. In this technique, a preoperative elevated body mass index, total bilirubin concentration, and prothrombin time increase the difficulty of lymph node dissection. This approach is expected to improve the efficiency of hepatic hilum lymph node dissection and shorten the learning curve; thus, this technique is worthy of further clinical promotion and application.
