Background Living donor liver transplantation (LDLT) in the elderly population is currently not well studied. There are single‐center studies indicating that patient age should not be a barrier to LDLT, with similar outcomes compared to younger recipients. Methods Using UNOS/STAR data from 2010 to 2022 we retrospectively analyzed patients ≥70 years old receiving a living donor graft (LDLT ≥70y group) versus a deceased donor graft (DDLT ≥70y group). In addition, we compared recipients ≥70 years old undergoing LDLT versus patients 18–69 years old also undergoing LDLT. Donor and recipient baseline characteristics, as well as postoperative outcomes including graft and patient survival were analyzed and compared between groups. Results Recipients in the LDLT ≥70y group showed less disease burden and spent significantly less time on the waitlist when compared to recipients in the DDLT ≥70y group (102 [49–201] days versus 170 [36–336] days) respectively; p = .004. With the exception of a longer length of stay (LOS) in the LDLT ≥70y group ( p ≤ .001), postoperative outcomes were comparable with recipients in the DDLT ≥70y group, including similar graft and patient survival rates at 1‐, 3‐, and 5‐years. When compared to younger recipients of a graft from a living donor, patients in the LDLT ≥70y group had similar post‐transplant functional status, re‐transplant rates and similar causes contributing to graft failure. However, significantly lower graft and patient survival rates were observed. Conclusion LDLT for recipients aged 70 or greater represents a faster access to transplantation in a safe and feasible manner when compared to similar‐ aged recipients undergoing DDLT.

Background Robotic transplant surgery has garnered worldwide attention since 2002. Discussions on this issue have led to more publications over the past decade. This study assessed global robotic organ transplantation studies using bibliometric analysis. Method The study sample was robotic technique use in organ transplantation publications from 2002 to 2021 in the Web of Science database. We analysed top‐cited authors, countries, institutions, journals, and keywords. Citations were used to visualise and analyse target literature in VOSviewer. Results 160 articles were included in the bibliometric study. Among the nations that are presently involved in the use of robotics in organ transplantation research, the United States of America leads robotic organ transplantation studies. The American Journal of Transplantation published the most articles overall. Conclusion Based on publication and citation numbers, robotic organ transplantation techniques are becoming more global attention. This robotic abdominal organ transplant surgery bibliometric analysis review covers research output and hotspots.
