Extra-visceral retroperitoneal echinococcosis (EVRE), represents an infrequent condition, even in endemic areas. Its best treatment option is surgery. The aim of this study was to determine postoperative morbidity (POM) and recurrence in patients with EVRE, surgically treated. Case series with follow-up of patients with EVRE undergoing surgery consecutively at RedSalud Mayor Temuco Clinic, between 2008 and 2019. The outcome variables were POM and recurrence. Other variables of interest were cyst diameter, surgical time, and hospital stay. Descriptive statistics was used. In this study, 12 patients (75.0 % male), with a median age of 46 years, were treated. The 58.3 % of cases were primary retroperitoneal cysts. The median of cyst diameter, surgical time, and hospital stay were 15 cm, 95 min, and 4 days respectively. The most frequent type of resection was total cystectomy (58.3 %). MPO was 8.3 % (there was urinary infection in one patient). No reoperations were necessary. There was no operative mortality. With a median follow-up of 90 months, a recurrence of 8.3 % was verified (one case). The results achieved, in terms of POM and recurrence were similar to other series.
