RESUMEN
Objective:To evaluate the safety and short-term efficacy of robotic-assisted resection for Bismuth-Corlette type Ⅲ and Ⅳ perihilar cholangiocarcinoma in Department of Pancreatobiliary Surgery,The First Affiliated Hospital,Sun Yat-sen University Methods:The clinical data of Bismuth-Corlette type Ⅲ and Ⅳ perihilar cholangiocarcinoma patients who have undergone robotic-assisted resection at The First Affiliated Hospital,Sun Yat-sen University between July 2017 and May 2023 were retrospectively studied.The clinicopathological features and perioperative outcomes of the patients were analyzed. Results:A total of 9 patients with Bismuth-Corlette type Ⅲ or Ⅳ perihilar cholangiocarcinoma,including 4 type Ⅲa patients,4 type Ⅲ b patients and 1 type Ⅳ patient,received robotic-assisted resection.1 patient converted to open surgery.The median operation time was 645 min[interquartile range(IQR):554-745 min],the median intraoperative blood loss was 300 mL(IQR:150-650 mL),and the median number of lymph node retrieval was 11(IQR:6-12).7 patients(77.8％)had R0 resection.5 patients(55.6％)had postoperative major complications(Clavein-Dindo classification was Ⅲ-Ⅴ),including intra-abdominal infection in 2 patients,liver function failure in 2 patients and upper gastrointestinal bleeding in 1 patient.1 patient underwent reoperation for the jejuno-jejunostomy bleeding 19 d after the initial operation and achieved good recovery.1 patient died within 30 d after initial operation due to liver function failure.The median length of postoperative hospital stay was 18 d(IQR:10-32 d). Conclusion:Robotic-assisted resection for Bismuth-Corlette type Ⅲ and Ⅳ perihilar cholangio-carcinoma is technically feasible and safe with good short-term efficacy,and can be performed in large-volume centers with ample experience in robotic-assisted hepatopancreatobiliary surgery.
