Percutaneous Treatment of Simple Hepatic Cysts: The Long-Term Results of PAIR and Catheterization Techniques as Single-Session Procedures.

Abstract

PURPOSE:

The purpose of our study is to evaluate results of percutaneous aspiration with alcohol sclerotherapy in symptomatic patients with simple hepatic cysts by employing single-session techniques either by a needle or a catheter.

MATERIALS AND METHODS:

We retrospectively included 39 simple hepatic cysts in 35 patients treated via percutaneous aspiration and single-session alcohol sclerotherapy between years 1993 and 2012. Indications were pain (n = 28) or ruling out cystic echinococcus (CE) disease (n = 7). 29 cysts in 26 patients were treated by needle technique (Group A) and ten cysts in nine patients were treated by single-session catheter technique (Group B). Patients were followed for 4-173 months (median: 38 months).

RESULTS:

All patients were successfully treated. Before procedure, cyst volumes were 21-676 cc (median: 94 cc). Post-procedure cyst volumes at last follow-up were 0-40 cc (median: 1 cc). The mean decrease in cyst volume was 95.92 ± 2.86 % in all patients (95.96 ± 3.26 % in Group A and 95.80 ± 6.20 % in Group B). There was no statistically significant difference between the volume reduction rates of Group A and Group B. Only one patient, in Group B, developed a major complication, an abscess. Hospitalization period was 1 day for all patients.

CONCLUSIONS:

For patients with symptomatic simple hepatic cysts smaller than 500 cc in volume by using puncture, aspiration, injection, and reaspiration (PAIR) technique with only needle, single-session alcohol sclerotherapy of 10 min is a safe and effective procedure with high success rate.
