AI Article Synopsis
- This study compares the outcomes of laparoscopic living donor right hemihepatectomy (LLDRH) and robotic living donor right hemihepatectomy (RLDRH) in a single institution over a six-year period.
- Results showed that RLDRH had longer operative times but less estimated blood loss compared to LLDRH; the complication rates were similar for both methods.
- The findings suggest RLDRH is better for cases with anatomical variations in blood vessels and highlight the benefits of standardizing procedures for enhanced minimally invasive donor surgeries.
Article Abstract
Background: Both laparoscopic living donor right hemihepatectomy (LLDRH) and robotic living donor right hemihepatectomy (RLDRH) have been developed for minimally invasive donor hepatectomy (MIDH), although comparative analysis between the two surgical modalities is lacking. This study aims to compare surgical outcomes of LLDRH and RLDRH at a single institution.
Materials And Methods: From March 2016 to March 2022, 171 patients who underwent MILH of right liver were enrolled and divided into RLDRH and LLDRH. Two surgeons with experience in both techniques performed all procedures. Clinical characteristics, perioperative outcomes of donor and recipient, and donor anatomic variations were compared between both groups, and learning curves were estimated. Subgroup analysis was also performed, including only donors recruited after 2019, when LLDRH was initiated at our institution.
Results: RLDRH and LLDRH were performed for 102 and 69 patients, respectively. Operative time was significantly longer for RLDRH than LLDRH (464 vs. 407 min, P < 0.001), although estimated blood loss was lower in RLDRH (104 vs. 238 mL, P = 0.002). Incidence of major complications was similar in both groups. After 2019, significantly more RLDRH vs. LLDRH patients had variation in the hepatic artery (14.3% vs. 2.9%, P = 0.020) and portal vein (16.1% vs. 4.3%, P = 0.027). Learning curve for RLDRH was stabilized after approximately the 16th case, whereas that of LLDRH stabilized immediately.
Conclusion: RLDRH resulted in less intraoperative bleeding and comparable postoperative outcomes than LLDRH. Moreover, since 2019, RLDRH has been employed more frequently for donors with hilar structure anatomic variations. Based on our single-center experience, we propose that standardized procedures for RLDRH might help set up pure minimally invasive procedures for donor hepatectomy and facilitate safe implementation of laparoscopic approaches.

Ann Intern Med

Renal-Electrolyte Division, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania (M.C.-P., R.B.M., C.M.P.).
Background: Prior studies indicate that 1% to 4% of Epstein-Barr virus (EBV)-seronegative recipients of EBV-seropositive donor (EBV D+/R-) kidneys develop posttransplant lymphoproliferative disorder (PTLD). However, these estimates are based on limited data that lack granularity.
Objective: To determine the associations between pretransplant EBV D+/R- and recipient EBV-seropositive status (R+) and the outcomes of PTLD and graft and patient survival among adult kidney transplant recipients.

Living-donor kidney transplantation is the preferred treatment for kidney failure. In the United States, rates of living kidney donation have been stagnant, which is partly related to concerns over medical and financial risks. Recent research has better characterized the risks of living kidney donation, although the field is limited by a lack of robust registries.

Optimizing the long-term care and follow-up of living kidney donors (LKDs) has been challenging, and prior LKDs have reported suboptimal healthcare experiences. Long-term care of LKDs is largely undertaken by primary care practitioners such as family physicians (FPs). We conducted a cross-sectional survey of Canadian FPs (n = 151).

Introduction: Hepatic epithelioid hemangioendothelioma (HEH) is a rare indication of liver transplant with limited evidence.
Methods: Adult recipients undergoing first-time liver-only transplant from 2002 to 2021 in the United States were identified using the UNOS/OPTN database. We compared post-transplant outcomes of recipients receiving liver transplant for HEH versus other diagnoses.

Introduction: Graft optimization is a necessity in order to develop uterus transplantation from brain-dead donors, as a complement to living donors, as these grafts are rare and the last organs retrieved in multiple organ donation. The aim of this study was to assess the feasibility and interest of hypothermic machine perfusion (HMP) in uterus transplantation using a porcine model; secondary outcomes were the evaluation of the graft's tolerance to a prolonged cold ischaemia time and to find new biomarkers of uterus viability.
Material And Methods: Fifteen uterus allotransplantations were performed in a porcine model, after 18 h of cold ischaemia, divided in three groups: Static cold storage in a HTK solution, HMP (with the VitaSmart (™) machine Bridge to Life Ltd.
