Laparoscopic robotic-assisted ileo-caecal resection with intracorporeal anastomosis in children with Crohn disease: initial experience of a paediatric center and surgical feasibility.

Purpose: Pediatric-onset Crohn's disease (CD) presents with a more aggressive course than adults. Surgical treatment is still necessary in many patients. The laparoscopic technique for treating terminal ileal CD is deemed safe and feasible, with the advantage to perform an intra-corporeal anastomosis (ICA). The robotic platform facilitates ICA creation thanks to 3D-visualization, tenfold magnification and better dexterity. The aim of this study was to report our initial experience of robotic ileocecal resection (RICR) with ICA in children with CD.

Methods: Six patients underwent RICR for CD. Patient characteristics, intraoperative details, and postoperative outcomes were collected. The surgical technique consisted in an intra-corporeal ICR with a stapled side-to-side ileo-colic anastomosis.

Results: The mean age at surgery was 14.8 years. The mean operative time was 210.8 min. No intraoperative complications or conversions were recorded. Bowel function returned on postoperative day 3 and the mean hospital stay was 8 days. Two minor complications were treated conservatively and 1 major (anastomotic dehiscence) required reoperation.

Conclusion: RICR is a safe and feasible technique in pediatric CD of terminal ileum. The robot offers advantages over other techniques for the precision of the suture, avoiding extracorporeal anastomosis. However, larger studies are needed to confirm these preliminary results.
