Intraoperative rupture of benign mucinous cystadenoma does not increase its recurrence rate

Purpose Laparoscopy has become the standard of care in the management of ovarian benign mucinous cystadenomas. One concern of the operative approach is the risk of recurrence. A previous study has found intraoperative cyst rupture and cystectomy to be the risk factors for recurrence. Our objective was to assess the incidence and risk factors for recurrence of benign mucinous cystadenomas after surgical removal. Methods We conducted a retrospective analysis of all cases of patients who underwent removal of benign mucinous cystadenomas by either cystectomy or adnexectomy in our institution between December 2006 and June 2013. Results 722 women underwent surgical treatment for benign ovarian cysts in that time period, out of which 38 women (5.2 %) had benign mucinous cystadenomas confirmed by pathologic examination. Most of the patients underwent laparoscopy (94.7 %). Half of the patients underwent cystectomy, and the other half underwent adnexectomy. One patient underwent re-operation due to cyst recurrence. This patient initially underwent laparoscopic cystectomy, during which intraoperative cyst rupture did not occur. Conclusion Recurrence of benign mucinous cystadenomas was uncommon and was not associated with intraoperative cyst rupture.
