The utility of robotic assisted pancreas transplants - a single center retrospective study

The prevalence of obesity within the diabetic population is on the rise. This development poses unique challenges for pancreas transplantation candidates as obese individuals are often denied access to transplant. The introduction of robotic approach to transplant has been shown to improve outcomes in obese patients. A single center retrospective review of pancreas transplant cases over a 4-year period ending December 2018 was performed. Patients undergoing robotic surgery were compared to their counterparts undergoing open transplant. 49 patients (10 robot, 39 open) received pancreas transplants over the study period. Mean age was 43.1 ± 7.5 vs. 42.8 ± 9.7 years. There were no significant differences in demographics except body mass index (33.7 ± 5.2 vs. 27.1 ± 6.6, P = 0.005). Operative duration (7.6 ± 1.6 vs. 5.3 ± 1.4, P < 0.001), and warm ischemia times [45.5 (IQR: 13.7) vs. 33 (7), P < 0.001] were longer in the robotic arm. There were no wound complications in the robotic approach patients. Graft (100% vs. 88%, P = 0.37) and patient survival (100% vs. 100%, P = 0.72) after 1 year were similar. Our findings suggest that robotic pancreas is both safe and effective in obese diabetic patients, without added risk of wound complications. Wide adoption of the technique is encouraged while long term follow-up of our recipients is awaited.
