Prolonged catheter drainage is more efficient for management of recurrent sterile fluid collections in acute pancreatitis than is conservative treatment. Conservative treatment is successful for patients with small fluid collections.
Continuous catheter drainage with negative pressure is more efficient than single-session alcohol sclerotherapy in the management of giant cysts. For moderately large cysts, the two methods have similar results.
To evaluate whether prolonged catheter drainage with negative pressure yields better results than single-session alcohol sclerotherapy in the treatment of symptomatic non-parasitic benign liver cysts. Forty patients were randomly assigned to two groups in a 24-month prospective controlled trial. One group was treated with ultrasound-guided prolonged catheter drainage with negative pressure (20 patients with 24 cysts) and the other group with single-session alcohol sclerotherapy (20 patients with 23 cysts). Patient demographics, clinical characteristics, treatment outcome, and complications were analyzed. The median volumes and 95% CI (confidence interval) for the medians and interquartile ranges of all 47 cysts before treatment and on last follow-up were: 389 ml, 143-1,127 ml, 136-1,300 ml, and 0 ml, 0-10 ml, and 0-23 ml, respectively (P<0.0001). The average volume reduction was 92.4% (range, 74.9-100%), 94.2 % (range, 74.9-100%) in the drainage and 90.2% (range, 76.9-100%) in the sclerotherapy group. Twenty-seven cysts (57.4%) disappeared completely, 16 (66.7%) in the drainage and 11 (47.8%) in the sclerotherapy group. No differences in average volume reduction, final volume and disappearance of the cysts between the groups were noted. The hospital stay was 1 day for all patients. Percutaneous treatment is safe and effective for hepatic non-parasitic cysts. Prolonged catheter drainage with negative pressure and single-session alcohol sclerotherapy had similar results.
PC is a safe and efficient treatment option for patients with AC who are less eligible for surgery. After patients recover from PC, further treatment such as cholecystectomy may not be needed.
An apparent association between the size of a simple renal cyst and hypertension was found, and aspiration of cysts resulted in a reduction of BP. Location and number of cysts were not related to BP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
