Based on our experience with 600 laparoscopic cholecystectomies, we present a new classification of anatomic variations of the cystic artery, which can be divided into three groups: (1) Calot's triangle type, found in 513 patients (85.5%); (2) outside Calot's triangle, found in 78 patients (13%); (3) compound type, observed in 9 patients (1.5%).CONCLUSION: Our classification of the anatomic variations of the cystic artery uncontrollable cystic artery extrahepatic bile duct injury. will be useful for decreasing hemorrhage, and avoiding extrahepatic bile duct injury.展开更多

And the knowledge of the normal anatomy and anatomical variations of the right hepatic artery is essential to perfume, and will minimize morbidity, and also help to decrease the number of complications of hepatobiliary surgery. This study was conducted on eleven human cadavers, which were obtained from the routine autopsies at the dissection room of the Anatomy Department. During dissection of the eleven cadaveric livers, we found a case with an ex-ceptional anatomic variation;a replaced right hepatic artery (RRHA) coming off the superior mesenteric artery (SMA), directly to the hepatic right lobe passing through the Calot’s triangle, crossing behind the common hepatic duct (CHD). <span style="font-family:Verdana;">Our objective is to draw much attention to this particularly anatomic variation of the origin of the RRHA as well as its clinical importance in order to ensure that no damage will be made during gastrointestinal and hepatobiliary surgery.</span>展开更多
