Ileum intussusception secondary to submucosal liposarcoma in adult：A case report

Abstract

Intussusception in adults is a rare surgical emergency. Unlike in children, most adult intussusceptions arise from a pathological lead point. Ileal intussusception caused by a submucosal liposarcoma is a particularly rare phenomenon. This report describes the diagnosis and management of adult ileal intussusception secondary to submucosal liposarcoma in adult to provide a reference for future clinical work. A 64-year-old female presented to the emergency department with worsening abdominal pain associated with an 8 h history of intermittent vomiting. Based on physical examination, laboratory investigations, and computed tomography, the most likely diagnosis was ileal intussusception secondary to liposarcoma. Thus, emergency laparotomy was performed. During exploration, an ileal invagination was visualised approximately 30 cm from the ileocecal valve, and a flexible polypoid mass was palpable at the lead point of the intussusception. Subsequently, the patient underwent radical resection of pathological tissues with a primary end-to-end ileal anastomosis. Histopathological examination revealed a well-differentiated submucosal liposarcoma. Postoperatively, the patient recovered uneventfully and was doing well at the 6-month follow-up in the outpatient clinic. Thus, clinicians should consider the origin of submucosal liposarcomas in adult with intussusception. Once ileal intussusception secondary to submucosal liposarcoma is diagnosed, timely radical resection is recommended.
