Adult Small Intestinal Intussusception Due to Bleeding Lipoma: A Rare Case Report (with Video).

Background and Clinical Significance: Adult small intestinal intussusception is rare and, in this population, is usually secondary to a pathological lead point, such as benign or malignant masses. The symptoms are non-specific, and patients frequently present with intermittent abdominal pain, diarrhea, nausea, vomiting, and, in rare cases, bleeding. There are currently no specific guidelines. Surgery remains the gold standard treatment. Case Presentation: We report the case of a 55-year-old female affected by Shone's syndrome, presenting to the emergency department with melena, severe anemia, diffuse abdominal pain, weakness, and palpitations. Diagnostic tests showed active bleeding in the small intestine and a subocclusive condition. Urgent surgery was performed, revealing an intussusception. Conclusions: A multidisciplinary approach is essential for its management. Surgical resection is the only option in these cases, as it allows histological examination to rule out malignancy.
