[Hepatic trisegmentectomy for 29 patients with huge neoplasms of liver].

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.
