Robot-assisted kidney transplantation is a safe alternative approach for morbidly obese patients with end-stage renal disease

Access to robotic assisted kidney transplant for recipients: a systematic review and call for reporting standards

Robot-assisted kidney transplantation (RAKT) is a relatively novel, minimally invasive option for kidney transplantation. However, clarity on recipient selection in the published literature is lacking thereby significantly limiting interpretation of safety and other outcomes. This systematic review aimed to identify and synthesize the data on selection of RAKT recipients, compare the synthesized data to kidney transplant recipients across the USA, and explore geographical clusters of availability of RAKT. Systematic literature review, in accordance with PRISMA, via OVID MEDLINE, Embase, and Web of science from inception to March 5, 2023. All data entry double blinded and quality via Newcastle Ottawa Scale. 44 full-text articles included, encompassing approximately 2402 kidney transplant recipients at baseline but with considerable suspicion for overlap across publications. There were significant omissions of information across studies on patient selection for RAKT and/or analysis. Overall, the quality of studies was very low. Given suspicion of overlap across studies, it is difficult to determine how many RAKT recipients received living (LD) versus deceased donor (DD) organs, but a rough estimate suggests 89% received LD. While the current RAKT literature provides preliminary evidence on safety, there are significant omissions in reporting on patient selection for RAKT which limits interpretation of findings. Two recommendations: (1) international consensus is needed for reporting guidelines when publishing RAKT data and (2) larger controlled trials consistently reporting recipient characteristics are needed to clearly determine selection, safety, and outcomes across both LD and DD recipients.

Application of robotics in abdominal organ transplantation: A bibliometric analysis

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.

ChatGPT and Artificial Intelligence in Transplantation Research: Is It Always Correct?

INTRODUCTION

ChatGPT (OpenAI, San Francisco, California, United States) is a chatbot powered by language-based artificial intelligence (AI). It generates text based on the information provided by users. It is currently being evaluated in medical research, publishing, and healthcare. However, there has been no prior study on the evaluation of its ability to help in kidney transplant research. This feasibility study aimed to evaluate the application and accuracy of ChatGPT in the field of kidney transplantation.

METHODS

On two separate dates, February 21 and March 2, 2023, ChatGPT 3.5 was questioned regarding the medical treatment of kidney transplants and related scientific facts. The responses provided by the chatbot were compiled, and a panel of two specialists reviewed the correctness of each answer.

RESULTS

We demonstrated that ChatGPT possessed substantial general knowledge of kidney transplantation; however, they lacked sufficient information and had inaccurate information that necessitates a deeper understanding of the topic. Moreover, ChatGPT failed to provide references for any of the scientific data it provided regarding kidney transplants, and when requested for references, it provided inaccurate ones.

CONCLUSION

The results of this short feasibility study indicate that ChatGPT may have the ability to assist in data collecting when a particular query is posed. However, caution should be exercised and it should not be used in isolation as a supplement to research or decisions regarding healthcare because there are still challenges with data accuracy and missing information.

Robotic kidney transplantation from deceased donors: a single-center experience

Robotic-assisted kidney transplant (RAKT) has proven to be a successful approach for patients with elevated body mass index (BMI). To date, a paucity of studies comprehensively analyzing the clinical outcomes of RAKT by using the grafts from deceased donors exists. This was a single-center retrospective analysis of RAKT from deceased donor kidneys (n = 93) from 2009 to 2021. The cohort was divided into 3 groups on the basis of recipient BMI (BMI ≤ 41.2 vs BMI 41.2-44.5 vs BMI ≥ 44.5 kg/m², n = 31). Delayed graft function was significantly higher in the group with the highest BMI (BMI ≤ 41.2 vs BMI 41.2-44.5 vs BMI ≥ 44.5 kg/m², 12.5% vs 10% vs 45.16%, P = .001). Graft survival after 12 months of follow-up was significantly lower in the group with BMI of ≥44.5 kg/m² (BMI ≤ 41.2 vs BMI 41.2-44.5 vs BMI ≥ 44.5 kg/m², 93.7% vs 100% vs 83.9%. P = .05). For BMI, the relative risk of patient survival was 1.10 for each increase in a BMI in the range of 5 (CI 95%, 0.98-1.21). Death-censored graft survival after 5 years was significantly better than the UNOS-matched cohort (dRAKT vs match, 86.2% vs 68.9%, P = .03). This single-center analysis shows that RAKT can be performed safely; however, caution should be used when matching marginal kidneys with patients with high BMI.

An ethical analysis of obesity as a contraindication of pediatric kidney transplant candidacy

The inclusion of body mass index (BMI) as a criterion for determining kidney transplant candidacy in children raises clinical and ethical challenges. Childhood obesity is on the rise and common among children with kidney failure. In addition, obesity is reported as an independent risk factor for the development of CKD and kidney failure. Resultantly, more children with obesity are anticipated to need kidney transplants. Most transplant centers around the world use high BMI as a relative or absolute contraindication for kidney transplant. However, use of obesity as a relative or absolute contraindication for pediatric kidney transplant is controversial. Empirical data demonstrating poorer outcomes following kidney transplant in obese pediatric patients are limited. In addition, pediatric obesity is distributed inequitably among groups. Unlike adults, most children lack independent agency to choose their food sources and exercise opportunities; they are dependent on their families for these choices. In this paper, we define childhood obesity and review (1) the association and impact of obesity on kidney disease and kidney transplant, (2) existing adult guidelines and rationale for using high BMI as a criterion for kidney transplant, (3) the prevalence of childhood obesity among children with kidney failure, and (4) the existing literature on obesity and pediatric kidney transplant outcomes. We then discuss ethical considerations related to the use of obesity as a criterion for kidney transplant.

Robotic live donor hysterectomy

PURPOSE OF REVIEW

Donor hysterectomy for live donor uterus transplantation was from the start performed by laparotomy, but minimal invasive surgery has entered the scene. In particular robotic-assisted laparoscopy is used since robotics is advantageous in the complex donor hysterectomy surgery in narrow space. This review covers the development and benefits of robotics and the published robotic donor hysterectomy experiences.

RECENT FINDINGS

Robotic donor hysterectomy publications are scarce with eight cases in Sweden, five in USA, and one each in China and Spain. Robotics have been performed for either the entire donor hysterectomy or with conversion to laparotomy for the last steps of the surgical procedure. The total operative times are in line with open surgery, although a decrease is expected in the future. The estimated blood loss and hospital stays are less than at open surgery. The complication panorama includes hydronephrosis, ureteric fistula and pressure alopecia. Live births with healthy babies have been reported.

SUMMARY

In uterus transplantation, robotic live donor hysterectomy has proven to be feasible, safe and associated with successful live births. The robotic donor hysterectomy is a low-volume procedure and an international registry to gather collective information is crucial for further evaluation and development.
