Adult Intestinal Intussusception Caused by the Gastrojejunostomy Tube: An Endoscopically Treatable Phenomenon

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Medical Case Reports

Background:

• Adult duodenoduodenal intussusception is exceptionally rare, often linked to neoplastic causes or complications from enteral tubes like gastrojejunostomy (GJ) tubes.
• The retroperitoneal fixation of the duodenum typically prevents such intussusceptions in adults.

Observation:

• A 23-year-old male presented with duodenoduodenal intussusception following percutaneous endoscopic gastrojejunostomy (PEGJ) tube placement.
• The patient exhibited gastroduodenal dilation and a telescoping phenomenon, with a 4-cm enteroenteric intussusception noted without signs of obstruction or ischemia.

Findings:

• This case represents the first reported instance of intussusception in an adult attributed to a GJ tube.
• Endoscopic intervention successfully reduced the intussusception, preventing potential bowel wall compromise.

Implications:

• This case expands the known etiologies of adult intussusception to include PEGJ tubes.
• Rapid endoscopic diagnosis and intervention offer a non-surgical management option for this rare condition, avoiding the need for surgery.
