Comparison between the stripping technique and the combined excisional/ablative technique for the treatment of bilateral ovarian endometriomas: a multicentric, randomized study

INTERVENTION: Each patient with bilateral endometriomas underwent to a single laparoscopy to remove the cysts. In the same laparoscopy two different techniques were performed: excisional stripping technique on one side versus combined technique (partial stripping and bipolar coagulation on last part on hilus) on the other side. Each patient received both surgical techniques performed at either side after random assignment. The mean duration of surgery was comparable between the two techniques and it was approximately 20 minutes. Duration of study: one year. CONDITION: Endometriosis PRIMARY OUTCOME: Ovarian reserve assessed using ovarian volume and Antral Follicle Count (AFC) as ultrasound markers SECONDARY OUTCOME: Recurrence rate of endometrioma assessed by ultrasound Symptom recurrence assessed by Visual Analogue Scale (VAS) INCLUSION CRITERIA: ‐bilateral ovarian endometriomas larger than 3cm ‐pelvic pain ‐infertility
