Laparoscopic Fenestration Versus Percutaneous Catheter Drainage for Lymphocele Treatment After Kidney Transplantation

Abstract

BACKGROUND: Laparoscopic fenestration (LF) and percutaneous catheter drainage (PCD) are widely accepted treatments for symptomatic lymphoceles. The aim of this study was to review the results and compare the outcomes of LF with those of PCD. PATIENTS AND METHODS: Among 1363 patients who underwent kidney transplantation at our institute between 1999 and 2011, 35 (2.5%) developed symptomatic lymphoceles. Among them, 7 were treated by LF after PCD; 10, LF only, and 18 PCD only. The patients were divided into 2 groups based upon the treatment method: LF (n = 17) and PCD-only groups (n = 18). RESULTS: No intergroup differences in age, gender, diabetes prevalence, retransplant rate, delayed graft function, or serum creatinine was observed at 7 days after the treatment. However, acute rejection episodes and sirolimus use were more frequent among the LF group (P = .028). Furthermore, median drainage on the first day was significantly greater in the LF versus PCD group. After catheter insertion, the PCD group showed a significant decrease in drainage on the following day, but no decrease was observed in the LF group. CONCLUSIONS: LF is a safe treatment for symptomatic lymphocele. LF should be held in reserve for treatment failures after PCD. LF seems to be a more reasonable first-line treatment for symptomatic lymphoceles in patients at high risk for graft dysfunction.
