Management of injuries to the porta hepatis
Insights
Managing porta hepatis injuries is complex due to associated organ damage and hemorrhage. Prioritizing hemorrhage control and performing expeditious operations improves survival rates for these challenging trauma cases.
Area of Science:
- Hepatobiliary surgery
- Trauma management
- Vascular surgery
Background:
- Injuries to the porta hepatis present significant management challenges.
- These injuries often occur with damage to other organs, complicating initial repair.
- Associated major vascular injuries and exsanguinating hemorrhage are common.
Purpose of the Study:
- To review the management strategies and outcomes of patients with porta hepatis injuries.
- To identify factors influencing morbidity and mortality in these complex cases.
Main Methods:
- Retrospective review of 31 patients with porta hepatis injuries.
- Analysis of surgical interventions for hepatic artery, bile duct, and portal vein injuries.
- Evaluation of patient survival rates and associated complications.
Main Results:
- Eighteen of 31 patients survived porta hepatis injury.
- Hepatic artery injuries were managed with ligation.
- Complex bile duct injuries often required secondary enteric-ductal anastomoses.
- Portal vein injuries were treated by ligation, lateral repair, or interposition grafting.
- Portal vein injury was associated with the highest morbidity and mortality.
Conclusions:
- Initial management prioritizes hemorrhage control and expeditious surgery.
- Anatomic reconstruction may be secondary to life-saving interventions.
- Portal vein injuries represent the most critical component of porta hepatis trauma.
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.
