Surgical Management of Metastatic Small Bowel Cancer with Intussusception: Two case reports

Intussusception in adults, a rare disease, constitutes approximately 5% of all intussusceptions and accounts for 5% of all cases of intestinal obstruction. In the pathologic findings of the causative lesion, metastatic tumors of the small intestine with intussusception are extremely rare. Because of the high prevalence of underlying lesions in intussusception in adults, surgical management is mandatory. We report two cases of intussusception; one was an adult patient who developed an ileo-ileal type, metastasis from lung cancer, and the other patient was an adult who was developed jejuno-jejunal type, metastasis from a malignant melanoma of the thumb.
