Abstract

Purpose The aim of this study was to investigate the efficacy and safety of percutaneous sclerotherapy for non-parasitic splenic cysts (NPSCs). The secondary aims were to introduce puncture-aspiration-injection-reaspiration (PAIR) technique in the treatment of NPSCs and to compare multiple- and single-session techniques. Materials and Methods This retrospective study included 24 (17 females, 7 males) patients, treated between the years 1997 and 2015. Three techniques were used. Group A (n = 8), Group B (n = 6) and Group C (n = 10) were treated by PAIR, single-session catheterization and multiple-session catheterization, respectively. Since both PAIR and single-session catheterization techniques are carried out in a single session, Group A and Group B were evaluated in one group (Group A + B). Group A + B was compared with Group C in terms of patient demographics, the initial volume of the cysts, follow-up periods, complication and hospitalization rates and follow-up results. Recurrence and reduction rates were evaluated for two groups. Results Technical success rate was 100%. The mean follow-up period was 68.9 months. Recurrence detected in 7 (29.1%) patients. Final reduction rate was between 40.7 and 100% (median 96.4%) with a significant difference in cyst volume (p < 0.05). There was no significant difference regarding recurrence rates (p = 1) and the final reduction rates (p = 0.51) between the two groups. Conclusion Percutaneous sclerotherapy is a minimally invasive technique, preserving maximum tissue while effectively treating NPSCs. Single-session sclerotherapy which reduces hospitalization days and increases patient comfort is as effective as multi-session sclerotherapy as the initial procedure. This study supports that single-session sclerotherapy should be a valid treatment option.
