Retroperitoneal echinococcosis (RE) is a rare condition that is associated with a high mortality and disability rate. It is associated with a high rate of misdiagnosis, a high risk of surgery, and is extremely difficult to manage. There is no uniform standard for determining the exact form of surgical method and the timing of surgery.This was a retrospective analysis of the characteristics and surgical management of patients diagnosed with RE in our hospital between 2012 and 2019.Between 2012 and 2019, 1257 cases of echinococcosis and 121 cases of RE were diagnosed in our hospital. Of these, 68 cases involved surgical treatment, 53 involved non-surgical treatment, and 12 cases were lost to follow-up (4 cases in the surgical group and 8 cases in the non-surgical group). Thus, 109 cases were followed-up. RE cases were divided according to different treatment methods into a radical resection group (Group A, 31 cases), a non-radical resection group (Group B, 37 cases), and a non-surgical group (Group C, 53 cases). We carried out a detailed analysis of the 109 cases experiencing surgical intervention with effective follow-up.Our analysis found that radical resection is the first line of treatment of RE, although non-radical surgery can benefit most patients. It is important to emphasize the importance of the first round of surgery, particularly in cases involving hepatic echinococcosis. If the lesion can be removed radically during the first round of surgery, then radical surgery should be performed.
