[Radiologic diagnosis of retrograde jejunogastric invagination following gastrectomy].

Retrograde jejunogastric invagination is a rare late complication of operations on the stomach. Clinically signs and symptoms (colic-like upper abdominal pain, cyclindrical resistance and hematemesis) resemble that of high ileus. This complication, when wrongly interpreted or unknown, has a high mortality. One case following delivery shows the radiologic signs.
