What is the average duration of a laparotomy with removal of adhesions and endo lesions including a presacral neurectomy in a stage 3 endo patient?

Varies: Endometriosis is a chronic condition. Most manage the syndrome medically. If surgery is required, most prefer laparoscopy over an open laparotomy. Lysis of adhesions may be brief or extensive. Pre sacral neurectomy is a complicated procedure which should be done as a last resort, by common opinion. Talk with your provider. Ask about recurrence, complications and success rates. Hang in there.
