Recurrence of cystic echinococcosis in an endemic area: a retrospective study

Abstract

[EN]Cystic echinococcosis (CE) is a chronic, complex and neglected zoonotic disease. CE occurs worldwide. In humans, it may result in a wide spectrum of clinical manifestations, ranging from asymptomatic infection to fatal disease. Clinical management procedures have evolved over decades without adequate evaluation.: A descriptive longitudinal-retrospective study was designed. We reviewed all patients diagnosed with CE according to ICD-9 (code 122–0 to 122–9) criteria admitted at Complejo Asistencial Universitario de Salamanca, Spain, between January 1998 and December 2015.Among the 217 patients studied, 25 (11.5%) had a hydatid recurrence after curative intention treatment.Median duration of recurrence’s diagnosis was 12.35 years (SD: ±9.31). The likelihood of recurrence was higher[OR = 2.7; 95% CI, 1.1–7.1; p < 0.05] when the cyst was located in organs other than liver and lung, 22.6% (7/31) vs14.2% (31/217) in the cohort. Consequently, large prospective and multicenter studies will be needed to provide definitive recommendations for its clinical managemen.t
