¿Es la comunicación quisto-biliar, un factor de riesgo para el desarrollo de morbilidad postoperatoria en pacientes con hidatidosis hepática?

Abstract

Intrabiliary rupture of hydatid cysts as a risk factor for postoperative complications Background: Intrabiliary rupture is a complication of hepatic hydatid cysts. Aim: To determine if intrabiliary rupture is a risk factor for postoperative complications of hydatid cysts. Material and Methods: Prospective follow up of patients operated for hepatic hydatid cysts between 1996 and 2006. Patients were evaluated every six months during the first years and every 12 months thereafter. The presence of intrabiliary rupture was evaluated as a risk factor to develop complications during the follow up. Results: Ninety six patients with and 156 patients without intrabiliary rupture, 56% females, aged 42 years, were followed for a mean of 86.5 months. The overall incidence of complications was 17%. The incidence in patients with and without intrabiliary rupture was 9,4 and 21,8% respectively (p = 0.01). The bivariate analysis showed differences between patients with and without complications in leukocyte count, serum bilirubin, alkaline phosphatases, transaminases, cyst diameter, hospital stay and cyst complications. The relative risk for complications of intrabiliary rupture was 3,4 (95% confidence intervals 2,6-4,2). Conclusions: The presence of intrabiliary rupture of a hepatic hydatid cyst is an independent risk factor for the development of complications in the postoperative period.
