Jejunostomy tube-induced intussusception

Intussusception involves the telescoping of a segment of bowel into an adjacent segment. It is the leading cause of intestinal obstruction in the pediatric age group; however, it is relatively rare and accounts for just about 1% of the cases of small bowel obstruction in adults. Jejunostomy tube-induced intussusception is an extraordinarily rare complication of feeding jejunostomy tube placement, the exact mechanism of which is not definitively known. The diagnosis of jejunostomy tube-induced intussusception is not easy as it generally does not interfere with the enteral feeding. Computed tomography (CT) scan is widely considered to be the imaging modality of choice in the diagnostic evaluation of adult intussusception. The finding of a heterogeneous sausage-shaped soft-tissue mass consisting of an outer intussuscipiens and central intussusceptum is virtually pathognomonic of intussusception. Surgery is the mainstay of management in an adult with intussusception. Nonoperative treatment strategies including radiologic reductions aided by hydrostatic/contrast/air enemas, which have mainly been attempted in the pediatric age group, have shown unpredictable results and are not recommended in adults. We present an unusual cause of jejunostomy tube-induced intussusception following a salvage laryngopharyngoesophagectomy and gastric pull-up in a patient with a postchemoradiation residue of a locally advanced carcinoma of the postcricoid region. A high degree of suspicion among clinicians and timely imaging with a CT scan are prerequisites for diagnosing intussusception in patients who complain of persistent gastrointestinal symptoms, especially with a jejunostomy tube in situ
