Bowel invagination intestinal intussusception is a rare condition in adults.In most cases,it is caused by a benign or malignant intestinal tumor.It refers to a condition in which a segment of the intestine invaginates into the lumen of its adjacent segment.The postoperative intussusception after gastrointestinal surgery is an uncommon clinical condition.Here,we report two cases of spontaneous small bowel intussusception following total gastrectomy.Intussusception is an extremely rare complication after gastric surgery;the incidence is reported to be<0.1%.Intussusception is attributed to both mechanical factors,and functional factors due to bivagotomy.Bowel invagination must be considered in the the postoperative period after gastrectomy.
