Clinicopathological Feature of Adult Small Bowel Intussusception Diagnosed and Managed by Double-Balloon Enteroscopy : A Single Centre Study

Abstract Background: Adult small bowel intussusception usually has an aetiology that leads to small bowel obstruction. Here, we aimed to identify the clinicopathological features of adult small bowel intussusception managed with Balloon-Assisted Enterosopy (BAE) and to explore the clinical usefulness of BAE for the management of small bowel intussusception.Method: We retrospectively analysed the clinical data of 13 patients who were diagnosed with adult small bowel intussusception at Korea University Guro Hospital between 2010 and 2019.Results: The type of intussusception was ileoileal in eight (61.5%) patients and jejunal-jejunal in five (38.5%) patients. Eight cases of small bowel intussusception (61.5%; five idiopathic causes, two Peutz-Jeghers polyps, and one Crohn’s disease) were successfully managed with BAE. The remaining five patients underwent laparoscopic small bowel resection due to management of the primary aetiology (two diffuse large B-cell lymphoma, one lipomatosis, one Peutz-Jeghers polyps, and one angiomyolipoma).Concusions: In many cases, adult small bowel intussusception had a benign and idiopathic aetiology. The diagnosis and treatment of adult small bowel intussusception with BAE may reduce the requirement for small bowel resection in selected patients.
