ObjectiveTo investigate the clinical feasibility and value of laparoscopic precise segment Ⅳ hepatectomy by guiding of indocyanine green (ICG) fluorescence imaging via ligamenta teres hepatis. MethodThe clinicopathologic data of patients with liver cancer treated in the Department of Liver Surgery of West China Hospital of Sichuan University from January 2017 to December 2021 who underwent precise segment Ⅳ hepatectomy by the guidance of ICG fluorescence imaging through the ligamenta teres hepatis were collected retrospectively. ResultsA total of 6 patients were collected, including 5 males and 1 female. The age ranged from 42 to 78 years. All 6 patients were successfully completed using laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis. The operation time was (200±30) min, the intraoperative bleeding was (100±20) mL, and there were no intraoperative blood transfusion, postoperative liver failure, postoperative pneumonia, incision infection, bile leakage, postoperative bleeding, and other complications. The postoperative hospital stay was (7±2) d. One patient with positive microvascular invasion was found after operation and recurred at 38 months after operation, then treated by radiofrequency ablation and didn’t recur. No patient died during the follow-up period in 6 patients. ConclusionFrom results of limited cases in this study, laparoscopic precise segment Ⅳ hepatectomy by guiding of ICG fluorescence imaging via ligamenta teres hepatis is safe, feasible, and effective.
