Robotic ileocolic resection with intracorporeal anastomosis for Crohn's disease

The robotic platform can overcome limitations of the laparoscopic approach, particularly in the facilitation of intracorporeal anastomosis creation. We aim to share our institutional experience with robotic ileocolic resection for Crohn's disease (CD) and compare it to a laparoscopic cohort. We identified patients who underwent ileocolic resection for CD with a purely robotic (R) or laparoscopic (L) approach between February 2015 and 2018. Chart review was performed and preoperative, intraoperative, and postoperative data was collected. A total of 47 patients with a mean age of 35.2 years old were identified and 61% were female. Seventy percent [n = 33, (23 females, 69.6%)] of the cases were performed robotically and 30% of the cases [n = 14, (6 females, 42.8%)] were performed laparoscopically. The groups were well matched for age, gender, BMI as well as disease related factors (CD duration; clinical classification and location), perioperative immunosuppression, and surgical history. Time to bowel function was shorter by about 1 day in the robotic group (R: 1.9 ± 0.88 days vs. L: 2.7 ± 0.8 days, p = 0.003). Mean operative time was longer in the robotic group by 51 min and this difference was significant (p = 0.03), however 30.3% of patients underwent ureteral stent placement, which can account for added time in robotic cases. There were less conversions in the robotic group [R: 1(4.3%) vs. L: 1(7%)], but this was not significant. There were no intraoperative complications in either group. Complication (L: 21.4% vs. R: 15.1%, p = 0.605) and reoperation rates (L: 0% vs. R: 3.03%, p = 0.429) were similar. Robotic ileocolic resection for Crohn's disease is as safe and feasible as the laparoscopic approach. This was accomplished with no leaks, major morbidity or mortality and comparable length of stay, with 1 day shorter return of bowel function, and with a lower overall complication rate. The robotic approach offers advantages in Crohn's disease which should be studied further in prospective studies.
