Abstract
A 79-year-old man underwent total gastrectomy because of advanced gastric cancer. Before surgery, he was suffering with severe chronic obstructive pulmonary disease, and malnutrition, a 9Fr feeding jejunostomy tube was installed for the purpose of early postoperative enteral nutrition.
He was discharged 22 days after surgery, but 24 days later, he was readmitted to hospital complaining of abdominal pain and vomiting. Abdominal CT revealed a target sign, and CT angiography of the small intestine revealed a Crab claw-like shadow. He was diagnosed with intussusception caused by a feeding jejunostomy tube. At laparotomy, there was no adhesion in the abdominal cavity, but we found an antegrade intussusception about 20 cm in length at the periphery to 5 cm from the Y-anastomosis. Intussusception of the small intestine by a small enteral feeding tube is rare, but has to be considered as a cause of post-operative ileus.
