title: Does intraoperative spillage of benign ovarian mucinous cystadenoma increase its recurrence rate?
abstract: OBJECTIVE
  To report a higher than estimated recurrence rate of benign mucinous cystadenomas after complete resection of the first one, and to assess potential risk factors for recurrence after complete surgical excision.
  
  
  METHODS
  We retrospectively reviewed all cases of women who underwent either laparoscopic or laparotomic removal of benign mucinous adnexal cysts by either adnexectomy or cystectomy in our institution between 1996 and 2006.
  
  
  RESULTS
  Included were the data of 42 women who fulfilled study entry criteria. Three of them (7.1%) underwent a second operation because of a recurrence of the lesion. A significantly higher rate of women who had cyst recurrence had undergone cystectomy as opposed to adnexectomy (P < .05). Intraoperative rupture of cysts during cystectomy was also significantly associated with cyst recurrence (P < .03).
  
  
  CONCLUSIONS
  Mucinous cystadenoma recurrence is apparently not as rare as reported in the literature. Intraoperative cyst rupture and cystectomy instead of adnexectomy emerged as being two risk factors for recurrence.
