Abstract
The management of injuries to the porta hepatis is challenging and controversial. Although definitive, anatomic reconstruction of injured ductal or vascular structures is optimal, porta hepatis injuries are universally accompanied by injuries to other organs (3.6 in this series), which often precludes initial repair. Moreover, frequent injury to the inferior vena cava, aorta, or other major blood vessels in addition to the structures of the porta hepatis results in these injuries being treated in conjunction with exsanguinating hemorrhage. For that reason, control of hemorrhage is the initial management priority, with the initial operation requiring expeditious, if less than anatomically exact, operations. Eighteen of 31 patients survived porta hepatis injury. Hepatic artery injuries were treated by ligation. Complex injuries to bile ducts frequently required enteric-ductal anastomoses as secondary procedures. Of 29 patients with portal vein injuries, six were treated by ligation, 22 by lateral repair, and one with splenic vein interposition graft. As in earlier reports, the structure of the porta hepatis associated with the highest morbidity and mortality rates when injured was the portal vein.
