ABSTRACT

This review discusses anatomical facts that are of relevance to the performance of a safe cholecystectomy. Misinterpretation and Illusion of normal anatomy and anatomical variation contribute to the occurrence of major postoperative complications like biliary injuries following a cholecystectomy, the incidence being higher with lap chole. A look at the basic anatomy is therefore important for biliary and minimally invasive surgeons. This include normal anatomy and variations of the biliary apparatus as well as arterial supply to the gallbladder. Specific anatomical distortion due to the laparoscopic technique, their contribution in producing injury and a preventive strategy based on this understanding are discussed. Investigative modalities that may help in assessing anatomy are considered. Newer insights into the role of anatomic illusions as well as the role of a system based approach to preventing injuries is also discussed.
