Jejunogastric intussusception: a case report with the review of literature.

Jejunogastric intussusception (JGI) is a rare but potentially lethal complication of gastrectomy or gastrojejunostomy. In the acute setting, early diagnosis and prompt surgical intervention are mandatory to avoid mortality. We present a case of JGI in a patient with a history of gastrojejunostomy who had increasing vomiting, hematemesis, and abdominal pain for 1 day.
