ABSTRACT
In laparoscopic cholecystectomy (LC), the treatment of iatrogenic biliary tract injury has been given much attention. However, most accidental right hepatic artery (RHA) injuries are treated with simple clipping. The reason is that the RHA has difficulty in revascularization, and it is generally considered that RHA injury does not cause serious consequences. However, some studies suggest that some cases of RHA ligation can cause a series of pathological changes correlated to arterial ischemia, such as liver abscess, bile tumor, liver atrophy and anastomotic stenosis. Theoretically, RHA blood flow should be restored when possible, in order to avoid the complications of right hepatic ischemia. The present study involved two patients, including one male and one female patient. Both patients were admitted to the hospital with the diagnosis of chronic cholecystitis and gallbladder stone, and developed ischemia of the right half hepatic after accidental transection of the RHA. Both patients underwent continuous end-end anastomosis of the RHA with 6-0 Prolene suture. After the blood vessel anastomosis, the right half liver quickly recovered to its original bright red. No adverse complications were observed in follow-ups at three and six months after the operation. Laparoscopic repair of the RHA is technically feasible. Reconstruction of the RHA can prevent complications associated with right hepatic ischemia.
