Peritoneal ports for treatment of intractable ascites.

PURPOSE: To present clinical data for a new peritoneal port for minimally invasive treatment of intractable ascites that can be used for aspiration in a patient's home. MATERIALS AND METHODS: Twenty-eight consecutive peritoneal ports were placed in 27 patients with intractable ascites. Ascites etiology was malignancy in 22 patients, cirrhosis in three, pancreatic duct injury in one, and unknown in one. Technical and clinical success and complications were evaluated until the time of death or the end of the study. RESULTS: All ports were inserted successfully with removal of all ascites, and all patients had immediate and complete symptom relief. Ascites was managed by periodic drainage, typically by a visiting nurse in the patient's home. The long-term clinical success rate was 96%, with 26 of 27 patients exhibiting maintained relief of symptoms until death or the end of the study. The long-term patency rate was 100% after 1,810 patient-days. Only one patient (4%) had a major complication. This was a port leak that required port exchange. Subsequently, the patient developed bacterial peritonitis. CONCLUSION: Peritoneal ports appear to be a safe, effective, minimally invasive treatment for intractable ascites. This device allows for reliable ascites aspiration in the patient's home.

Uterine artery embolization: sonographic imaging findings.

OBJECTIVE: To examine the sonographic and angiographic imaging findings before and after uterine fibroid embolization for symptomatic leiomyoma. METHODS: This prospective study involved 14 premenopausal women who underwent uterine fibroid embolization for symptomatic leiomyoma. Preprocedure sonography with color Doppler imaging was performed. Bilateral uterine artery embolization was successfully performed with the use of polyvinyl alcohol. Follow-up sonographic examinations were performed between 1 and 3 months after the procedure. The correlation between the sonographic appearance before and after embolization and the degree of decrease in uterine size was evaluated by using the Jonckheere-Terpstra 2-sided P test. RESULTS: Preprocedure sonographic imaging showed a varied appearance to the fibroids. Color Doppler imaging primarily showed the fibroids to be vascular with marked peripheral blood flow. Postprocedure sonographic imaging showed decreased uterine size and echogenicity. Color Doppler imaging showed a marked decrease in the blood flow to the leiomyoma. There was no statistical significance in the relationship between echogenicity and vascularity shown before the procedure and the percent decrease in the size of the uterus. CONCLUSIONS: Although sonography is an efficient method for identifying leiomyomata and determining the reduction in size after uterine artery embolization, we were unable to identify any predictive characteristics of success for aiding the preprocedural assessment.
