Abstract

Hepatothoracic transit, evolutionary complications of hepatic echinoccocosis Introduction: Hepatothoracic transit (HTT) is one of the evolutionary complications of hepatic echinoccocosis (HH). The aim of this study is to describe clinical characteristics and morbidity of a series of patients with HTT surgically treated. Material and Methods: Prospective series of cases. Patients operated by HTT between 1997 and 2007 in Regional Hospital of Temuco, Chile, with a minimum follow-up of 12 months and clinical controls at months 1, 6, 12, 24, 36, 48 and 60. End point was development of morbidity. Descriptive statistic was used, applying central tendency and dispersion measured. In addition confidence intervals of 95% was calculated. Results: The series is composed by 23 patients with HTT with a median age of 48 years (16 to 75 years) and 56% femenine. Median cyst diameter was 20 cm (8 to 30 cm) 78.3% of the lesions were located in the right lobe of the liver. The most frequent surgical technique used was subtotal cystectomy (78.3%); residual cavity were treated preferably by capitonage (30.4%) or epiploplasty (34.8%). With a median follow-up of 71 months (12 to 122 months), one verified that no patient required surgical reintervencion; mortality rate was 4.3% (one patient) and registered morbidity was 26.0% (6 patients). Conclusion: HTT is associated to considerable values of post-operative morbidity and mortality.
