Two hundred women aged from 20 to 35 years undergoing conservative laparoscopic treatment of
ovarian endometriomas (either by drainage or cyst wall excision) were included. Participants
were randomized into 4 groups; group A (drainage only) in which 50 patients underwent
laparoscopic fenestration and electrocautery of the endometrioma cyst wall, group B
(cystectomy only) in which 50 patients underwent laparoscopic excision of the endometrioma
cyst wall, group C (drainage & Surgicel) in which 50 patients underwent laparoscopic
fenestration of the endometrioma cyst wall followed by insertion of 4 pieces of Surgicel
inside the cyst cavity, group D (cystectomy & Surgicel) in which 50 patients underwent
laparoscopic excision of the endometrioma cyst wall followed by insertion of 4 pieces of
Surgicel inside the remaining ovarian tissues.All patients were followed up every 3 months
for 2 years following the laparoscopic surgery. The primary outcome was the recurrence of
endometriomas in the ipsilateral ovary (recurrence was defined as the presence of ovarian
cysts with the characteristic sonographic features of endometriomas (≥1 cm). The ovarian
reserve was reassessed (AMH & day 2 AFC) as a secondary outcome 6 months following the
laparoscopy.
