Model of Li et al for Surgical Site Infection Following Resection of a Perihilar Cholangiocarcinoma

Description

Li et al developed a model for predicting surgical site infection after resection of a perihilar cholangiocarcinoma (Klatskin tumor). The authors are from Dingxi People's Hospital, Lanzhou University, Sichuan Provincial Hospital for Women and Children and Sichuan University.


Patient selection: radical resection of a perihilar cholangiocarcinoma (hepatectomy combined with hepaticojejunostomy)

 

Outcome: surgical site infection (superficial or deep incisional, organ space)

 

Parameters:

(1) coexisting cholangiolithiasis

(2) history of previous abdominal surgery

(3) blood loss in mL

(4) bile leakage

Performance:

• The area under the ROC curve is 0.85.
