to investigate the efficacy and long-term results of sclerotherapy for peritoneal inclusion cysts (PICs).

Between January 2000 and november 2007, thirty patients with PICs(range: 19-80 years; mean age, 45.5 years) and thirty-one PICs were included in this study. The chief complains were low abdominal discomfort or pain, palpable mass, voiding frequency, extremity edema or incidentally detected large cysts. After drainage via an 8-10 Fr pigtail catheter inserted in the PICs (transabdominally in twenty-eight cases, transvaginally in three), sclerosant (povidone-iodine in thirteen, ethanol in eighteen) equivalent in volume to about one third of drained fluid was instillated for 15 minutes. Instillation of the sclerosant was repeated once a day until the drained volume was less than 5ml. Patients were evaluated after 1, 4 month and then every 6 months by clinical assessment and ultrasound.

Sclerotherapy was technically successful in all thirty patients. No immediate major complication developed except mild abdominal pain or fever in eight patients. During the follow-up period of 7-92 (mean, 33.5) months, PICs were completely disappeared in seventeen, and diameter of the cyst was decreased more than 50% without symptom in ten. The overall long-term success rate was 87.1% (27/31). There is no significant difference of success rate between the povidone-iodine (84.6%, 11/13) and ethanol (88.9%, 16/18)groups. The rate of complete remission in ethanol(55%, 10/18)groups is higher than one in povidone-iodine(46%, 6/11)groups. Recurrence of PIC occurred in four patients. In two patients, PICs completely regressed without further recurrence after re-sclerotherapy. The other one patient underwent surgery and the remaining one is under regular follow-up.

Sclerotherapy following catheter insertion is a safe, effective and reliable method for the treatment of PICs.

Sclerotherapy can be considered to treatment of choice for PIC, instead of conservative management such as oral contraceptives or surgery with relatively high recurrence rate.
