Minimally invasive biliary anastomosis after iatrogenic bile duct injury: a systematic review.

Abstract

Major bile duct injuries (BDIs) may require complex surgical repairs that are usually performed with a conventional open approach. This study aims to analyze current evidence concerning the safety and the outcomes of the minimally invasive (MI) approach for biliary anastomosis in post-cholecystectomy BDIs. A systematic search of MEDLINE, Embase, and Web-Of-Science indexed studies involving MI (laparoscopic or robotic) biliary anastomosis in patients with iatrogenic BDIs was performed. The quality of the studies was assessed using the MINORS criteria. A total of 13 studies involving 198 patients were included. One hundred and twenty-five patients (63.1%) underwent a laparoscopic biliary anastomosis, while 73 (36.1%) received an analogue robotic procedure. All the included BDIs were types D and E (E1-E5). The mean OT varied between 190 and 330 (mean = 227) minutes. Ten studies reported the mean intraoperative blood loss that ranged between 50 and 252 (mean = 135.9) mL. No conversions occurred in the robotic series, while four patients required conversion to open surgery among the laparoscopic ones. The mean length of postoperative hospital stay was 6.3days. The reported overall morbidity was similar among the robotic and laparoscopic series. During the follow-up period, no surgery-related mortality occurred. A growing number of referral centers are showing the safety and feasibility of the MI approach for biliary anastomosis in patients with major BDIs. Further prospective comparative studies are needed to draw more definitive conclusions.
