Description

Milliken et al reported models for predicting morbidity following partial hepatectomy for a hepatic tumor. One model is based on variables from the revised Frailty Index (rFI) of Gani et al. The authors are from the Royal Free London NHS Foundation Trust.


Patient selection: partial hepatectomy for hepatic tumor

 

Outcome: 90-day major complications (Clavien-Dindo Grade III or greater including death)

 

Parameters:

(1) extent of surgical resection

(2) serum albumin

(3) hematocrit

(4) ASA performance status
