title: Sclerotherapy of cervical cysts with Picibanil (OK-432).
abstract: The effectiveness of intralesional sclerotherapy of lymphangiomas and ranulas with OK-432 (Picibanil) has been proved in several clinical studies. The aim of our study was to review the effectiveness of sclerotherapy of benign cervical cysts with Picibanil as an alternative method to surgical excision. Between March 2002 and March 2006, a prospective observational study was carried out to assess the effects of Picibanil on cervical cysts. Between 2002 and 2006 we treated 14 patients having cervical cysts through intralesional application of Picibanil with a dose of 0.01 mg/ml. So far we used Picibanil with 13 patients achieving a high success rate. In eight cases we observed, both clinically and ultrasonographically, a nearly complete regression, and a complete regression of the cysts in three cases. In two cases the cysts atrophied. In these cases only residual findings could be observed. In one case we extirpated the remaining cyst. If there is no clear reaction of the cyst to the treatment, an excision is indicated 6 weeks after the injections to gain meaningful histological examination. No significant complication after sclerotherapy with Picibanil was observed. According to our results the application of OK-432 (Picibanil) is a safe and effective primary method for sclerotherapy of benign cervical cysts which can replace surgical extirpation in special cases. However, the risk of malign diseases has to be excluded before the commencement of the Picibanil treatment.
