Steatosis predicts postoperative morbidity following hepatic resection for colorectal metastasis.
BACKGROUND
Few studies are available on the effect of steatosis on perioperative outcome following hepatic resection for colorectal liver metastasis (CRLM).


METHODS
Patients undergoing resection for CRLM from January 2000 to September 2005 were identified from a hepatobiliary database. Data analysed included laboratory measurements, extent of hepatic resection, blood transfusion requirements and steatosis.


RESULTS
There were 386 patients with a median age of 66 (range 32-87) years, of whom 201 had at least one co-morbid condition and 194 had an American Society of Anesthesiologists grade of I. Anatomical resection was performed in 279 patients and non-anatomical resection in 107; 165 had additional procedures. Steatosis in 194 patients was classified as mild in 122, moderate in 60 and severe in 12. The overall morbidity rate was 36 per cent (139 patients) and the mortality rate was 1.8 per cent (seven patients). Admission to the intensive care unit, morbidity, infective complications and biochemical profile changes were associated with greater severity of steatosis. Independent predictors of morbidity were steatosis, extent of hepatic resection and blood transfusion.


CONCLUSIONS
Steatosis is associated with increased morbidity following hepatic resection. Other predictors of outcome were extent of hepatic resection and blood transfusion.
