The right hepatic artery is a branch of the intrinsic hepatic artery and supplies blood to the right liver. The right hepatic artery is a branch of the intrinsic hepatic artery and supplies blood to the right side of the liver. The liver is supplied with nutrients from the portal vein and oxygen from the hepatic artery, which mainly serves to nourish and provide nutrients to the liver. However, in some patients, the gallbladder artery may also undergo variation, and some patients may have the gallbladder artery branching off through the common hepatic artery or through the left hepatic artery. For the course of the gallbladder artery, it is safer and more secure to dissect as close to the gallbladder as possible, and then disconnect the gallbladder artery after confirming that the vessel has entered the gallbladder. For patients undergoing laparoscopic cholecystectomy, the dissection of the cystic duct is the main focus. After dissecting out the entire abdomen, the exact location of the cystic duct is considered, and then the cystic duct is dissected.
