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.
