Lipoma of the transverse colon with intussusception: A case report / 대한내과학회지

Colonic lipomas represent the most frequent mesenchymal benign tumors of the large intestine after hyperplastic polyps and adenomatous polyps, but the pathogenesis is unclear. These tumors are composed of mature fatty tissue and usually arise in the submucosa. They are usually solitary and small, and may be sessile or pedunculated. Most patients are asymptomatic and their tumors are often detected incidentally, but tumors larger than 2 cm tend to produce change in bowel habit, abdominal pain, rectorrhagia and complications such a luminal obstruction or intestinal intussusception. Diagnosis may be aided by colonoscopy with biopsy, barium enema and computed tomography. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve. Some cases of such lipoma of transverse colon have been reported in Europe and the United States, but rare in Korea. We report a case of lipoma of the transverse colon that was originated in subserosa and presented as a intussusception in a 63-year-old woman with brief review of literatures.

Two Cases of Acute Mesenteric Infarction Due to Superior Mesenteric Arterial and Venous Branch Occlusion

Acute mesenteric infarction is a catastrophic illness representing a diverse spectrum of pathologic conditions which ultimately lead to necrosis of the intestine and which is uniformly fatal if left untreated. Despite better understanding of the disease process, acute mesenteric infarction continues to be a lethal disorder with high mortality rate. We experienced two cases of acute mesenteric infarction due to superior mesenteric arterial and venous branch occlusion, respectively, in recent years: One case was focal segmental ischemia with normal radiologic finding including angiography, successfully treated with segmental resection of the necrotized ileum, another case was mesenteric venous thrombosis, also treated with resection of necrotized small intestine followed by second look operation.
