Ileocecal intussusception secondary to giant ileal lipoma in patient with chronic constipation: a case report.

Introduction: Intussusception in adults is rare, comprising 5% of cases, and is often associated with pathological lesions like polyps or tumors. This report highlights a case of ileocolic intussusception due to a giant terminal ileal lipoma incidentally found during a colonoscopy. Case presentation: A 53-year-old male presented with chronic constipation, mild abdominal pain, and rectal bleeding for 2 years. The patient used laxatives in the past for constipation but it did not improve. A colonoscopy revealed protrusion of the small intestine through the ileocecal valve into the cecum with a 3 cm lipoma as the leading point. A CT scan of the abdomen was performed, revealing findings suggestive of intussusception. The patient underwent laparotomy, the lipoma was excised, and the intussusception was resolved. Clinical discussion: Symptoms of intestinal lipoma vary widely, from acute obstruction to incidental imaging findings. Surgical intervention is typically necessary to address the underlying cause, such as gastrointestinal lipomas found predominantly in the right colon. The causes of intussusception in patients, such as lipoma, tumor, or polyp, can be found accidentally during routine colonoscopy. Conclusion: Intussusception in adults can present with chronic constipation and mild abdominal discomfort.
