Description

Halls et al reported the Southampton score for predicting the difficulty of performing a laparoscopic liver resection. The authors are from University Hospital Southampton, University of Southampton, Ghent University, Groeninge Hospital, San Raffaele Hospital, Oslo University Hospital, University of Oslo, Antoine-Beclere Hospital and University of Navarra Hospital.


Patient selection: laparoscopic liver resection

 

Parameters:

(1) neoadjuvant chemotherapy

(2) previous open liver resection

(3) type of lesion

(4) diameter of the lesion in cm

(5) classification of the resection

Performance:

• The area under the ROC curve for intra-operative complications was 0.68.

• The area under the ROC curve for 90-day mortality was 0.77.
