Aspectos clínico-quirúrgicos de la hidatidosis hepática, una zoonosis de creciente preocupación

Abstract

Hydatidosis is common in Southern Chile and it is usually located in the liver. The complications of surgical procedures for liver hydatidosis, which fluctuate from 11 to 86 percent, are superposed to the own complications of the disease. The frequency of surgical complications is associated with evolutionary complications of the cysts, the need to perform additional procedures to treat the disease in other simultaneous locations and previous surgical interventions for the disease. Operative mortality is lower than 5 percent. The surgical treatment of hydatidosis is divided in four phases: isolation of the surgical zone, cyst evacuation, treatment of cyst complications and treatment of residual cavity. The conservative surgical procedures are marsupialization, cystostomy, Posadas intervention and cystojejunostomy. Surgical procedures involving resection are pericys-tectomy, subtotal cystectomy and liver resections. The role of laparoscopic surgery is still under evaluation. (AU)
