Abstract
BACKGROUND: The objective was to analyze the outcomes of thoracoscopic mesh repair for hepatic hydrothorax (HH) at our institution during the past 10 years. METHODS: A total of 63 patients with refractory HH who underwent thoracoscopic mesh onlay reinforcement to repair diaphragmatic defects from January 2005 to December 2014 were included in the study. Mesh covering alone was used in 47 patients and mesh with suturing was used in 16 patients. Patient demographics, Child-Pugh class, and model for end-stage liver disease (MELD) score were evaluated to predict morbidity and mortality. RESULTS: Of the patients (mean age, 60.4 ± 15 years; 31 men and 32 women), 14.3% had concomitant underlying diseases of renal insufficiency, 34.9% had diabetes mellitus, and 4.8% had pneumonia. Diaphragmatic blebs were the most common diaphragmatic defects (29 of 63 [46%]). After a median 20.5 months of follow-up examinations, 4 patients experienced recurrence. The 1-month mortality rate was 9.5% (6 of 63 patients). On multivariable analysis, underlying impaired renal function (p = 0.039) and MELD scores (p = 0.048) were associated with increased 3-month mortality in 16 patients. Contrary to the rising Child-Pugh score (p = 0.058), rising MELD scores represented an increase in kidney or liver failure and mortality. The main causes of 3-month mortality were septic shock (n = 6), acute renal insufficiency (n = 4), gastrointestinal bleeding (n = 4), hepatic encephalopathy (n = 1), and ischemic bowel (n = 1). CONCLUSIONS: Thoracoscopic mesh repair for refractory HH improves symptoms and lowers the recurrence rate.
