Senior versus Proctored Young and Resident Surgeons' Experience in Laparoscopic Cholecystectomy: Is There Any Need of Previous Exposure to Open Biliary Surgery?

Abstract

Since its introduction in 1987 laparoscopic cholecystectomy (LC) has gained rapid acceptance as the preferred management of symptomatic cholelithiasis. In our department, during the past 3 years, the number of open cholecystectomies (OCs) has dramatically decreased. The impact of the introduction of LC as a part of the overall surgical procedures performed by residents is analyzed. To date junior-level residents have already more experience in LC than in OC. Indeed in our teaching unit junior-level residents performed only 5% of biliary surgical procedures in open surgery. Residents participated in the "surgeon's" position in 47.9% of the LCs and as either surgeon or first assistant in 100%. We analyzed both the cases where residents acted as surgeons and where they did not. It appeared that there was no difference in the complication and conversion rates. More intraoperative cholangiographies (IOCs) were performed by residents. This was probably due to the anxiety of making a mistake because of their lack of experience. This report suggests that the decrease in the number of OCs is not a drawback and that it is possible to acquire an adequate knowledge of biliary anatomy and surgery from LC training, if strict proctoring criteria are respected.
