Introduction: Intestinal intussusception occurs when a bowel segment telescopes into the lumen of an adjacent segment. Untreated intussusception can lead to bowel obstruction and ischemia of the bowel wall. Intussusception is rare in adults, representing only 5% of all cases, but is a life-threatening condition. Adult intussusception is often due to malignancy, but other causes include benign tumors, adhesions, inflammatory bowel disease, and surgical anastomoses. Jejunogastric intussusception (JGI) is a rare but serious complication of gastric surgery and carries a mortality rate as high as 50%. The recommended treatment is surgical reconstruction of the affected site to prevent recurrence. This case describes the utility of endoscopy to diagnose and reduce JGI. It also highlights the importance of surgical repair as the definitive management.
Case Description/Methods: A 68-year-old man presented to the emergency department with intractable abdominal pain, nausea, and vomiting. He had undergone a Whipple Procedure for pancreatic adenocarcinoma five years earlier. A physical exam revealed stable vitals and a soft abdomen with tenderness in the epigastric area without rebound or distension. An abdominal CT scan revealed a masslike protrusion in the gastric lumen. Upper endoscopy showed JGI, which was reduced with insufflation. After the endoscopy, the patient had full resolution of his symptoms. It was recommended that he undergo prompt surgical reconstruction of the anastomosis of his Whipple Procedure, however, he refused. Less than twelve hours later, his symptoms returned. He underwent a successful conversion of the anastomosis to a Roux-en-Y bypass and has not had a recurrence of JGI since.
Discussion: JGI after gastric surgery can occur at any point in the postoperative period, from days to decades later. It carries a high mortality rate if not addressed surgically. Endoscopy can be a useful tool when diagnosing and reducing non-malignant intussusception, and some case reports have even described endoscopy alone as a potential conservative approach to intussusception. However, in the presence of a lead point like a previous surgical anastomosis, the recurrence risk of JGI is high and requires prompt surgical repair.
