Robotic right live donor hepatectomy (r-LDRH) has been reported with reduced morbidity compared to open donor right hepatectomy (o-LDRH) in few recent series. Nevertheless, its routine use is debated. We present a large series comparing pure r-LDRH with o-LDRH. Consecutive r-LDRH performed from June 2018 to June 2020 (n = 102) were compared with consecutive donors undergoing o-LDRH (n = 152) from February 2016 to February 2018, a period when r-LDRH was not available at this center. Propensity score matched (PSM) analysis of 89 case-control pairs was additionally performed. Primary endpoints were length of high dependency unit (HDU) and hospital stay and Clavien-Dindo graded complications among donors. Although r-LDRH took longer to perform (540 vs. 462 min, P < .001), the postoperative peak transaminases levels (P < .001), the length of HDU (3 vs. 4 days, P < .001), and hospital stay (8 vs. 9 days, P < .001) were lower in in donors undergoing r-LDRH. Clavien-Dindo graded complications were similar (16.67% in r-LDRH and 13.16% in o-LDRH). The rates of early allograft dysfunction (1.6% vs. 3.3%), bile leak (14.7% vs. 10.7%), and 1-year mortality (13.7% vs. 11.8%) were comparable between r-LDRH and o-LDRH recipients. PSM analysis yielded similar results between the groups. These data support the safety and feasibility of r-LDRH in select donors.

RAPID-Type Auxiliary Liver Transplantation for Unresectable Colorectal Liver Metastases: A First-Stage Surgical Video.

Background: The Resection and Partial Liver Transplantation with Delayed Total Hepatectomy (RAPID) procedure for unresectable colorectal liver metastases (uCRLM) has renewed interest by increasing, in selected cases, patients' long-term survival. Initially described using deceased donor graft, this technique evolved to living donors, tackling organ-shortage issues, allowing better scheduling, and reducing liver failure risk.
Methods: A 50-year-old patient presented 18 months earlier with a colic adenocarcinoma with synchronous uCRLM.

surgery and autotransplantation may provide a promising option for radical resection of conventionally unresectable liver tumors. Two cirrhotic patients with hepatocellular carcinoma (HCC), which has an "awkward seat" located in the "intrahepatic vascular triangle area (IVTA)" that consists of the middle hepatic vein (MHV), the right branches of the Glisson sheath, and the inferior vena cava (IVC), underwent extended right-half hepatectomy followed by tumor resection and partial liver autotransplantation. Innovatively, the outflow of the tumor-free liver was reconstructed using pre-frozen allograft blood vessels from brain-dead donors; the patients recovered well postoperation.

ABO-compatible Orthotopic Liver Transplantation (OLT) is the standard treatment for patients with acute liver failure (ALF) who meet the criteria for poor prognosis. Contraindications to liver transplantation may be related to the presence of severe medical or psychiatric comorbidities, or to an unstable clinical state incompatible with transplantation. Early mortality predictive scores and factors have been developed to identify futile transplantations that exacerbate organ shortage.

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.
