Background: Geographic inequities are known to affect access to liver transplant (LT); however, the impact of these disparities postoperatively remains unknown. We focus on primary care physicians (PCPs), as frequent managers of long-term LT recipient care.
Methods: Clinical data on adults undergoing liver-only transplant 2010-2021 were obtained from the Organ Procurement and Transplantation Network and linked to zip code-based PCP density and social vulnerability index (SVI) data to quantify the impact of PCP density on graft and overall survival.
Article Synopsis
- Robotic kidney transplant (RKT) is explored as a safe alternative to open kidney transplant (OKT), despite previous selection biases affecting patient comparisons.
- A study comparing outcomes from 50 RKT patients and 100 OKT patients found that while RKT had longer operative and warm ischemia times, it also resulted in less blood loss and lower rates of post-operative complications.
- Overall, RKT demonstrates significant advantages over OKT, suggesting its potential to become the new standard of care for patients with end-stage renal disease (ESRD).
We investigated the use of robotic objective performance metrics (OPM) to predict number of cases to proficiency and independence among abdominal transplant fellows performing robot-assisted donor nephrectomy (RDN). 101 RDNs were performed by 5 transplant fellows from September 2020 to October 2023. OPM included fellow percent active control time (%ACT) and handoff counts (HC).

Although focused on similar operations, each program offers distinct clinical and technical emphases.
Design: An annual inter-institutional exchange between TXP-HPB and SO fellowships, starting in 2014.
Background: Robotic donor nephrectomy (RDN) has emerged as a safe alternative to laparoscopic donor nephrectomy (LDN). Having previously demonstrated comparable efficacy, this study aims to examine postoperative analgesia use (opioid and non-opioid) in the two groups.
Methods: We conducted a retrospective review of 300 living donor nephrectomies performed at our center, comparing 150 RDN's with a contemporary cohort of 150 hand-assisted LDN's.
Liver transplantation is the only curative treatment of many patients with HCC. To be successful, patients must undergo careful multidisciplinary evaluation and neoadjuvant treatment for bridging or downstaging. Patients with stable disease for 6 months are listed for transplant, after which regular surveillance is required to detect recurrence.

Methods: We performed a retrospective review of 150 consecutive living donor operations (75 LDN and 75 RDN) at our center, comparing the first 75 RDN's with the last 75 LDN's performed prior to the initiation of the robotic transplant program.
Background: Hepatic artery infusion pump (HAIP) therapy has become increasingly commonplace in the treatment of intrahepatic tumors. When combined with standard chemotherapy, HAIP therapy demonstrates a higher response rate than chemotherapy alone. Biliary sclerosis is observed in up to 22 % of patients, for whom no treatment has been standardized.

A new technology called normothermic machine perfusion (NMP) offers a way to recover marginal and declined livers for transplant.
View Article and Find Full Text PDFBackground: An increasing number of transplant centers have adopted robot-assisted living donor nephrectomy. Thus, a transplant fellow assessment tool is needed for promoting operative independence in an objective and safe manner.
Methods: In this pilot study, data was prospectively collected on both fellow performance with focus on technique, efficiency, and communication ("overall RO-SCORE"), and operative steps ("operative steps RO-SCORE").
Background: Diffusion-weighted imaging (DWI) is considered by experts as one of the key elements in multi-parametric magnetic resonance imaging (mpMRI) employed in oncological studies outside the brain. A low-to-high b value ratio DWI has been proposed as an approach to decrease acquisition time and simplify the analysis of DWI data without the need to use a mathematical model.
Methods: Forty-three men with biopsy-proven prostate cancer (PCa) who underwent mpMRI of the prostate were included.
