Robotic-assisted Roux-en-Y hepaticojejunostomy after bile duct injury.

Background: The Da Vinci Robotic Surgical System has positioned itself as a tool that improves the ergonomics of the surgeon, facilitating dissection in confined spaces and enhancing the surgeon's skills. The technical aspects for successful bile duct repair are well-vascularized ducts, tension-free anastomosis, and complete drainage of hepatic segments, and all are achievable with robotic-assisted approach.

Methods: This was a retrospective study of our prospectively collected database of patients with iatrogenic bile duct injury who underwent robotic-assisted Roux-en-Y hepaticojejunostomy. Pre-, intra-, and short-term postoperative data were analyzed.

Results: A total of 30 consecutive patients were included. The median age was 46.5 years and 76.7% were female. Neo-confluences with section of hepatic segment IV were performed in 7 patients (those classified as Strasberg E4). In the remaining 23, a Hepp-Couinaud anastomosis was built. There were no intraoperative complications, the median estimated blood loss was 100 mL, and the median operative time was 245 min. No conversion was needed. The median length of stay was 6 days and the median length of follow-up was 8 months. The overall morbidity rate was 23.3%. Two patients presented hepaticojejunostomy leak. No mortality was registered.

Conclusion: Robotic surgery is feasible and can be safely performed, with acceptable short-term results, in bile duct injury repair providing the advantages of minimally invasive surgery. Further studies with larger number of cases and longer follow-up are needed to establish the role of robotic assisted approaches in the reconstruction of BDI.
