The surgical treatment of retroperitoneal echinococcosis: the experience of a single center
Abstract Background Echinococcosis refers to a worldwide epidemic of zoonotic parasites that commonly affect the human liver, lungs, and omentum and can be classified as cystic echinococcosis (CE) and alveolar echinococcosis (AE).Retroperitoneal echinococcosis (RE) is a rare condition that is associated with a high mortality and disability rate. Because RE manifests in a concealed and deep location, and can often involve several important organs, it is associated with a high rate of misdiagnosis, a high risk of surgery, and is extremely difficult to manage. Methods This was a retrospective analysis of the characteristics and surgical management of patients diagnosed with RE in our hospital between 2012 and 2019. Results 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 (four cases in the surgical group and eight 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; there were 31 cases of radical resection (Group A), 33 cases of non-radical resection (Group B). Conclusions Our analysis found that RE is rare and can occur at any age; the cystic form is common and often involves multiple organs. The liver is the most commonly affected organ and is associated with serious complications. The rate of radical resection for RE is low, and multiple organ resection is often required; there is a high incidence of postoperative complications. 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.
