Robotic liver partition and portal vein embolization for staged hepatectomy for perihilar cholangiocarcinoma

Abstract

Perihilar cholangiocarcinoma (pCCA) is one of the most complex challenges for hepatobiliary surgeons. Poor results and high incidence of morbidity after Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) for pCCA discouraged this indication. It has been proposed that minimally invasive approach for ALPPS first stage, as well as combination of surgical liver partition and radiologic portal vein embolization (PVE), may improve outcomes reducing interstage morbidity. We report a case of right trisectionectomy with enbloc caudatectomy ALPPS scheduled for pCCA with robotic approach at stage-1, the full video is provided as supplementary material. Due to intraoperative presence of portal vein tumor infiltration during hilar dissection (no evidence in the pre-operative work-up), a radiologic right PVE was performed after stage-1 instead of portal vein ligation, followed by portal vein resection and biductal hepatico-jejunostomy at stage-2 with open approach. The patient was a 74-year-old female diagnosed with 3-cm mass-forming pCCA. The total clean liver volume was 1231 cc, with future liver remnant (FLR) volume of 25.1% (segments II and III). She was discharged in the interstage interval on postoperative day (POD) 4; CT scan on POD 12 showed that FLR increased up to 33% (369 cc) (Fig. 1). ALPPS was completed on POD 17, the postoperative course was uneventful, and the patient was discharged in good general condition on POD 19 after stage-2. Besides the already demonstrated advantages in terms of reduced interstage morbidity, robotic ALPPS represents a promising strategy to expand surgical indication in patients with pCCA. The combination of liver partition and PVE may increase the opportunities to perform radical resections in selected patients with pCCA and portal vein infiltration.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13304-021-01209-x.
