Abstract

BACKGROUND/PURPOSE:

Mortality and morbidity rates after liver resections have decreased with better surgical techniques and perioperative care. The aim of this study was to evaluate the short- and longterm results in patients who had undergone extensive hepatectomies.

METHODS:

From January 1985 to December 2000, 237 patients underwent 275 liver resections for colorectal metastases. Extensive liver resections were defined as follows: technical reasons (extended hepatectomies, associated vascular resections); disease extent (diameter, >>10 cm; number, >>5; associated extrahepatic resection). The total number of extensive liver resections was 74. There were 51 radical resections (68.9%), while in the nonextensive resections group, 152 resections were radical (90.7%; P = 0.1).

RESULTS:

Postoperative mortality (60 days) was 1.6% (1.3% in the extensive resections group; P = 0.3), while morbidity was 22.7% (31% in the extensive resections group vs 19% in the nonextensive resections group; P = 0.1). One-, 3-, and 5-year overall actuarial survival rates were 91.8%, 44.9%, and 25.3%. The survival rates of patients who underwent an extensive resection were similar to those in the nonextensive resections group.

CONCLUSIONS:

Technical difficulties and neoplastic extension are not, nowadays, a contraindication for hepatectomy for colorectal liver metastases, unless a radical resection is performed. Mortality and morbidity rates after liver resections have decreased with better surgical techniques and perioperative care. The aim of this study was to evaluate the short- and longterm results in patients who had undergone extensive hepatectomies.
