[A Case of Primary Angiosarcoma of the Small Intestine Triggered by Gastrointestinal Bleeding].

An 87-year-old man with complaints of palpitations and digestive bleeding previously visited another hospital. He was referred to our hospital because of anemia. Small bowel endoscopy revealed an elevated lesion with bleeding from the ileum.

A technique for constructing diverting loop ileostomy to prevent outlet obstruction after rectal resection and total colectomy: a retrospective single-center study.

Purpose: Preventing outlet obstruction associated with a diverting stoma is important. Previously, we constructed a diverting loop ileostomy with the proximal limb of the small intestine on the caudal side, namely the oral inferior (OI) method. However, to address the issue of twisting and stenosis of the small intestine, we recently constructed a diverting loop ileostomy with the proximal limb on the cranial side, namely the oral superior (OS) method.
