Abstract
INTRODUCTION: Thoracic involvement (TIHE) is one of the evolutionary complications of hepatic echinococcosis (HE). AIM: The aim of this study was to describe the clinical characteristics and postoperative morbidity (POM) of a series of patients with TIHE treated surgically. MATERIAL AND METHODS: Series of cases of patients treated for TIHE between 2000 and 2014 in the Hospital Regional and Clínica Mayor in Temuco, Chile, with a minimum 12-month follow-up. The outcome variable was "development of POM". Descriptive statistics were used. RESULTS: The series was composed of 37 patients with a mean age of 53.2 ± 47.4 years (51.4% female). Mean cyst diameter was 19.4 ± 15.5 cm, and 75.7% of the lesions were located in the right hepatic lobe. The most frequent surgical technique used for the cyst was subtotal pericystectomy (56.8%); the residual cavity was treated by capitonnage (27.0%) or omentoplasty (21.6%), and a phrenoplasty with or without prosthetic material was performed for the TIHE. Mean hospital stay was 6.0 ± 5.7 days and follow-up was 61.4 ± 79.9 months; a mortality rate of 2.7% (one patient) and a POM of 24.3% (9 patients) were verified. CONCLUSION: TIHE is an uncommon evolutionary complication of HE associated with significant POM rate.
