Objective:
To evaluate the feasibility and effect of hepatic trisegmentectomy for patients with huge neoplasms of liver.
Methods:
From July 1993 to October 1999, 29 patients with huge hepatic neoplasms underwent hepatic trisegmentectomy, (23 patients with primary liver cancer, 1 patient with hepatic infiltration of gallbladder cancer, 1 patient with metastasis of colon cancer, 1 patient with hepatic angiosarcoma, 1 patient with hepatic neurofibroma, and 2 patients with huge liver cyst). Of these patients, 26 underwent right trisegmentectomies and the rest 3 accepted left trisegmentectomies. All trisegmentectomies were performed under normothermic interruption of the porta hepatis at single time and these interruptions lasted 15 to 40 minutes.
Results:
The relatively good effect was seen in our series of trisegmentectomies. The 1-, 3-, 5-year survival rates for patients with primary liver cancer were 63.6%, 36.4% and 27.3%, respectively. The survival time for patients with hepatic infiltration of gallbladder cancer and metastasis of colon cancer in the liver was 6 months. The patients with hepatic angiosarcoma, hepatic neurofibroma and 2 huge liver cysts survived 35, 26, 25, 40 months and 1 till to the latest follow-up, respectively. Main complications were present in 5 patients. Mortality within 1 month was 3.4% (1/ 29).
Conclusion:
Hepatic trisegmentectomy is safe and effective in treatment of huge hepatic neoplasms if its indications and operative techniques are mastered properly.
