Case Report: Repetitive Surgical Resections for Intestinal Intussusception due to Multiple Ileal Lipomatosis

Abstract

Adult intestinal intussusception is a rare disease known to be associated with intestinal tumors. We describe a case requiring partial ileal resection in 2 occasions due to intussusception from multiple lipomatosis. A 45-year-old Japanese man was referred to our hospital for detailed examination after positive fecal blood test results and intermittent abdominal pain. He was diagnosed with intussusception of the ileum due to multiple lipomatosis and underwent partial ileal resection. Three years after the first surgery, he again experienced intermittent abdominal pain and nausea, and was referred to our department. Contrast-enhanced computed tomography at this time also showed intussusception near the ileocecal valve, with several fat-density tumors. He underwent partial ileal resection as an emergency surgery, with the histologic diagnosis confirming ileal multiple lipomatosis. Repeated surgical resections are sometimes required for patients with intestinal intussusception due to lipomatosis, since lipomas not causing symptoms are often left untouched after minimal resection. Close follow-up such as contrast-enhanced CT and small-bowel endoscopy after surgery should be performed regularly so that the patients can avoid emergency surgeries because of the insufficient preoperative examinations.
