Non-operative management of a pelvic hydatid cyst communicating with the bladder.
Two cases are reported of spontaneous rupture of pelvic hydatid cysts into the bladder, which were managed conservatively. The resulting communication between the bladder and the cyst was used advantageously for intravesical instillation of 20% saline to destroy the germinal layer of the hydatid cyst and daughter cysts. Sequential cystographic studies showed disappearance of the extrinsic pressure effect on the bladder as the daughter cysts were evacuated repeatedly per urethram after instillations. Spontaneous sealing off of the communication was documented and confirmed by cytoscopy in 1 case. A plea is made to adopt a non-operative approach in such cases, which permits intravesical and, hence, intracystic scolecidal agent instillation and achieves spontaneous evacuation of daughter cysts. Other factors encouraging conservative management whenever possible are the reportedly high recurrence rate of hydatid cysts postoperatively, the morbidity described with complete excision of pelvic and other hydatid cysts, and the inherent slow process of recurrence (between 5 and 20 years) after complete evacuation of daughter cysts.
