Clinical outcomes associated with surgical treatment of endometrioma coupled with resection of the posterior broad ligament.

OBJECTIVE To evaluate clinical outcomes associated with the resection of both endometrioma and posterior broad ligament (PBL) among women with PBL adhesion associated with endometrioma. METHODS Between January 2007 and December 2009 at the Villanova Hospital, Florence, Italy, a prospective trial was conducted on 99 consecutive patients with unilateral or bilateral endometrioma who underwent laparoscopic ovarian cystectomy by a stripping technique and homolateral PBL resection where PBL adhesion was associated with endometrioma. The prevalence of PBL adhesion and endometriosis, the association between PBL endometriosis and pain, and the recurrence of endometrioma and pain were evaluated. All data were analyzed with Prism software. RESULTS Among 124 endometriomas treated by concomitant PBL resection, the PBL was not affected by adhesions in only 2% of patients. PBL endometriosis was superficial in 36 (29.5%) and deep in 86 (70.5%) of the histologic preparations; deep endometriosis correlated with preoperative pain. At 1-year follow-up, endometrioma had recurred in 7 patients; the main symptom reported was mid-cycle pain (24 patients, 24%; P=0.0007). CONCLUSION Ovarian endometriosis was often (98%) associated with PBL endometriosis; deep endometriosis of PBL correlated with pain symptoms. Although PBL resection increased the incidence of mid-cycle pain, it was associated with low recurrence of endometrioma.
