An analysis of the iatrogenic biliary injury after robotic cholecystectomy. Current data and future considerations

Minimally invasive techniques are the gold standard in surgery. Since conventional laparoscopic approach has been widely adopted, surgeons in their effort to further improve their skills passed to the era of the robotic assistance. The widespread adoption of robotics has led to the inevitable usage of robotic technology both in simple, as well as in more complicated procedures. Cholecystectomy is the "simple" surgical procedure to which every surgeon from the beginning of his career and besides specialization or subspecialization is exposed to, but the ran complications have a dramatic impact both for patient and doctor. The elimination of bile duct injury is crucial and robotics in the new era of surgery has to be the gold standard to a safe cholecystectomy.

A comprehensive search of PubMed Database was conducted for English-language studies using the MeSH terms [Robotic cholecystectomy, bile duct injury]. We reviewed references of all reports for additional cases from 2000 to nowadays. We used the related articles link and searched the citations of reports in the ISI Science Citation Index to identify additional reports.

A total of 16 studies, including 2.264 patients that underwent robotic cholecystectomy were analyzed. Postoperative data and complications were collected from these studies. Bile duct injuries were more likely to be discovered during the first postoperative days as a bile leakage (8/2.264). One major bile duct injury was noticed, and most injuries were definitively treated at the hospital where the injury occurred with postoperative endoscopic retrograde cholangiopancreatography (ERCP) and stenting.

Robotic cholecystectomy is a safe and adequate alternative to conventional laparoscopic or open approach in term of safety. Furthermore, surgeons must be already experienced and familiar with robotic techniques, so as to overcome the problem of the bile duct injury.
