The impact of deep disease on surgical treatment of endometriosis

Abstract Objective To compare the difficulty of surgery in patients with and without deeply infiltrating endometriosis. Study design Prospective cohort study performed in one hospital specialized in the surgical treatment of endometriosis. 193 consecutive patients undergoing excision of all visible endometriosis by laparoscopy (176 patients, 91.2%) or by laparotomy (17 patients, 8.2%). The duration of surgery, the number of operations, the number of day-surgery operations, the need to operate with a surgeon, the ability to perform complete excision during one operation, and the ability to perform operation by laparoscopy were compared in patients with and without deep lesions. Results The mean duration of surgery was 192 (SD 96), and 76 (SD 41) min in patients with and without deep lesions ( p p p p p p p  = 1.0). Complete excision was less often performed by laparoscopy in patients with deep lesions (79% vs. 95%, p Conclusions Surgical treatment of deep lesions is more demanding and time-consuming than surgical treatment of other types of endometriosis, and collaboration with a surgeon is often necessary. Complete excision during one operation is a realistic goal for endometriosis surgery, but it is significantly less often achievable by laparoscopy in patients with deep lesions than in patients without deep lesions.
