Intussusception is a rare cause of postoperative
intestinal obstruction in adults. Many retrograde
intussusceptions occur during the period following
gastrectomy. A 77-year-old woman visited our hospital because of detected gastric
adenocarcinoma. She received radical total
gastrectomy with Roux-en-Y esophagojejunostomy. On the fifth postoperative day, she complained of
abdominal pain, and we found leakage at the esophagojejunostomy site and dilatation of the Roux limb and the afferent limb of the jejunojejunostomy. Emergency surgery was performed. Retrograde jejunojejunal
intussusception accompanied with a nasojejunal
feeding tube was found at the efferent loop of the jejunojejunostomy. No ischemic change was found; therefore, manual reduction and primary repair of esophagojejunostomy was performed. She was discharged without complications on the 23rd re-postoperativeday. We suggest that the nasojejunal
feeding tube acted as a trigger of
intussusception because there was no definitive small bowel mass or postoperative adhesion. We present our findings here along with a brief review of the literature.
