Nomogram of Poupon et al for Predicting Complications After Surgery for Deep Endometriosis Without Bowel Involvement

Description

Poupon et al reported a nomogram for predicting complications following surgery for deep endometriosis without bowel involvement. This can help to identify a patient who may require more aggressive management. The authors are from Sorbonne University in France.

Patient selection: deep endometriosis without bowel involvement, from 15 to 55 years of age

Outcome: any Clavien-Dindo complications or voiding dysfunction lasting more than 1 month after surgery

Parameters:

(1) age in years from 15 to 55 years

(2) history of previous surgery for endometriosis

(3) risk group of ENZIAN classification

points for age =

= (1.5725 * (age)) - 23.5875

Parameter	Finding	Points
history of surgery	no	0
	yes	78.2
ENZIAN risk group	low	0
	intermediate	22.3
	high	100

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 241

• The higher the score the greater the risk of complications.

Score	Risk of Complications After Surgery in Percent
< 24.9	< 5%
24.9 to 241	(0.0007573 * ((score)^2)) + (0.008592 * (score)) + 4.348
