We report a case of retrograde jejunogastric intussusception in a patient with previous gastric surgery who required surgical treatment for its resolution. Operative findings were type II jejunogastric intussusception with retrograde invagination of a segment of efferent loop into the stomach. The acute jejunogastric intussusception is an emergent condition. Early and accurate diagnosis is important. A high susception must be kept in mind in patients having a history of gastrojejunostomy with severe abdominal pain or upper gastrointestinal bleeding. © Copyright Moreira Jr. Editora.
