Application of laparoscopy in perihilar tumor surgery

With the promotion of the concept of minimally invasive surgery, hepatobiliary surgery has gradually become a mainstream technique; however, for bile duct tumors in the perihilar region, there are few reports on the application of laparoscopy in such tumor due to the complex structure and anatomical variations of the hepatic hilar region. With reference to related reports in China and globally, this article introduces the research advances in the application of laparoscopy in perihilar tumor surgery. The analysis shows that laparoscopy has certain advantages in the surgical treatment of perihilar tumors, especially in the treatment of Bismuth Ⅰ/Ⅱ hilar cholangiocarcinoma and early-stage gallbladder cancer; due to the high requirements of laparoscopic surgery for the surgeon, only a few experts can perform this surgery at present, and strict screening and evaluation of patients are also required. Therefore, laparoscopy used in perihilar tumor surgery is still at the preliminary stage of exploration, with a need for further exploration and learning.
