Jejuno-jejunal intussusception in a post-lung transplant patient from a gastrojejunostomy tube: A case report

Introduction: Gastro-jejunostomy tube is used for post-pyloric feeding for critical-ill patient who cannot tolerate oral alimentation. Jejuno-jejunal intussusception is a rare complication of gastrojejunostomy tube. Presentation of case: A 39-year-old male with history of severe combined immunodeficiency, Achalasia and end-stage lung disease underwent double lung transplantation. After lung transplantation, he required gastrojejunostomy(GJ) tube placement due to his esophageal disease. Four days after gastrojejunostomy tube placement, he developed jejuno-jejunal intussusception. A 15 cm segment of thickened and enlarged bowel, which consisted of the intussusception were identified laparoscopically. Surgical reduction was performed without bowel resection. Discussion: Intussusception is uncommon in adults compared to pediatric population. In this rare case, the jejunal limb of the GJ tube placed in jejunum was the cause of jejunojejunal intussusception serving as the lead point. The GJ tube should not be placed farther down from ligaments of Treiz to prevent jejuno-jejunal intussusception. Conclusions: A heightened index of suspicion for this rare complication should exist with a presenting patient has signs of proximal bowel obstruction and CT evidence of intussusception.
