Although retrograde jejunogastric intussusception is rare as a post-gastrectomy complication, it is importantthat it be diagnosed as early as possible because of the high mortality in the acute type if surgery is not performed immediately. The clinical manifestations give some clue to the diagnosis, but a definite diagnostic method is Bariummeal examination. Three cases of retrograde jejunogastric intussusception are reported with abrief review of the literature. Among the three cases, two were the acute delayed type, and one was the acutepostoperative type. Also, two of the three were the efferent loop type.
