BACKGROUND: We sought to determine the prevalence of common anatomic landmarks around the gallbladder that may be useful in orienting surgeons during laparoscopic cholecystectomy.
METHODS: The subhepatic anatomy of 128 patients undergoing elective cholecystectomy was recorded. We searched and recorded the presence of five anatomic landmarks: the bile duct (B), the Sulcus of Rouviere (S), the left hepatic artery (A), the umbilical fissure (F), and the duodenum (E). These are the previously described B-SAFE landmarks.
RESULTS: We found that the duodenum and umbilical fissure were present reliably in almost all patients. The position of the left hepatic artery could be reliably determined by its pulsation in 84% of patients. A portion of the bile duct could be seen in 77% and the Sulcus of Rouviere was present in 80%. Furthermore, the hepatobiliary triangle was always found superior or at the same level as the Sulcus of Rouviere.
CONCLUSIONS: We found that these five anatomic landmarks were reliably present. This suggest that using the B-SAFE landmarks may allow a surgeon to more easily orient before and during laparoscopic cholecystectomy and prevent bile duct injuries.
