Small Intestinal Intussusception Due to Complicated Giant Jejunal Diverticulosis

Diffuse Jejunal Lipomatosis and Associated Complications

Small intestinal lipomatosis is a rare condition with a poorly understood epidemiology and pathophysiology. Cases of small intestinal lipomatosis have been documented in multiple countries over the last century, yet little has been published regarding the natural history of this disease. Therapeutic options are largely surgical and based on limited evidence. We report a unique case of diffuse jejunal lipomatosis in a 62-year-old man with complications of small bowel obstruction, small bowel volvulus, jejunal diverticulosis, pneumatosis intestinalis, malnutrition, small intestinal bacterial overgrowth, and intestinal dysmotility developing over a 12-year period.

Confluent Small Bowel Lipomatosis: A Rare Cause of Recurrent Abdominal Pain

Small intestine lipomatosis is rare but may be associated with pain, intussusception, and gastrointestinal bleeding. In this report, we examine the case of a 41-year-old man who had recurrent presentations to the emergency department with non-specific abdominal pain. Preoperative imaging suggested extensive infiltration of small intestine with macroscopic fat. At surgery, extensive and confluent small bowel lipomatosis were seen. The affected ileal segment was resected, and the patient remained symptom-free after surgery. Abdominal lipomatosis is a rare condition which can be completely treated by resection of the affected gut segment but is often unsuspected and difficult to diagnose. In this report, we describe a case with the most extensive lipomatosis on record with more than 70 cm of gut with confluent lipomatosis. Magnetic resonance Enterography (MRE) is a useful non-invasive diagnostic modality, although laparoscopy/laparotomy may be necessary for assessment of the extent of disease. Symptomatic cases should be treated with segmental small bowel resection, which is curative.
