title: Laparoscopic incidental appendectomy during laparoscopic surgery for ovarian endometrioma.
abstract: OBJECTIVE
  We sought to investigate the safety and efficacy of laparoscopic incidental appendectomy during laparoscopic surgery for endometrioma.
  
  
  METHODS
  We conducted a retrospective study of 356 patients undergoing laparoscopic surgery for endometrioma with appendectomy (appendectomy group, n = 172) or not (nonappendectomy group, n = 184). Primary outcome measures were operating time, hemoglobin change, hospital stay, return of bowel activity, and any complications. The secondary outcome was appendiceal histopathology.
  
  
  RESULTS
  There were no statistical differences between groups in operating time, postoperative changes in hemoglobin concentration, hospital stay, return of bowel activity, or complication rate. Of the 172 resected appendices, 52 had histopathologically confirmed abnormal findings including appendiceal endometriosis in 16.
  
  
  CONCLUSIONS
  Incidental appendectomy at the time of laparoscopic surgery for endometrioma does not increase operative morbidity, and it has considerable diagnostic and preventive value. However, a large prospective randomized study is needed in the future to confirm this conclusion.
