title: Effect of Surgical Removal of Endometriomas on Cyclic and Non-cyclic Pelvic Pain.
abstract: BACKGROUND
  Endometriosis is a complex disease with a spectrum of pain symptoms from mild dysmenorrhea to debilitating pelvic pain. There is no concrete evidence in the literature whether endometriotic cyst per se, causes pain spectrum related to the disease. The aim of the present study was to evaluate the effect of surgical removal of endome- triomas on pain symptoms.
  
  
  METHODS
  In this prospective, observational, before-after study, which was conducted between March 2012 and January 2013 in Training and Research Hospital,Adana, Turkey, a total of 23 patients including 16 sexually active and 7 vir- gin symptomatic women were questioned for non-cyclic pelvic pain (NCPP), intensity of the NCPP, presence of cyclic dysmenorrhea, and dyspareunia before and after the endometrioma operation. Participants who were sonographically diagnosed and later pathologically confirmed as having endometrioma without sign and symptoms of deep infiltrative endometriosis (DIE) were also questioned for pain symptoms before and after the laparoscopic removal of cyst wall. Patients with intraabdominal adhesions, history of pelvic inflammatory disease, and pathological diagnosis other than endometrioma were excluded. No ancillary procedures were applied for pain management, but if pain was present, pelvic peritoneal endometriotic lesions were ablated beside the removal of ovar- ian endometriotic cysts.
  
  
  RESULTS
  Out of 23 cases with endometrioma, 91 and 78% reported to have NCPP and dysmenorrhea, respectively, before the operation, while 60 and 48%, respec- tively, after the operation (McNemar's test, P=0.016 for both figures). Among the sexually active cases, 31% (5/16) had dyspareunia before the operation and only 1 case reported the pain relief after the operation (McNemar's test, P=1). Intensity of NCPP were reported to be none (8.7%), moderate (21.7%), severe (56.5%) and un- bearable (13%) before the operation and decreased to none (43.5%), mild (43.5%), moderate (4.3%) and severe (8.7%) after the operation (Wilcoxon signed-rank test, P<0.001).
  
  
  CONCLUSIONS
  In symptomatic cases with ovarian endometrioma, without sign and symptoms of DIE, laparoscopic removal of the cysts with/without ablation of the peritoneal endometriotic lesions yields relief of NCPP and cyclic dysmenorrhea, but not dyspareunia.
