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

Parameter	Finding	Points
coexisting cholangiolithiasis	no	0
	yes	1.91
history of previous abdominal surgery	no	0
	yes	1.77
blood loss	<= 1,500 mL	0
	> 1,500 mL	1.56
bile leakage	no	0
	yes	2.73

X =

= SUM(points for all 4 parameters) - 4.12

probability of surgical site infection =

= 1 / (1+EXP((-1)*X))

Performance:

• The area under the ROC curve is 0.85.
