Jejunogastric intussusception.

Jejunogastric intussusception is a rare complication after gastric surgery. Only 16 documented cases have been reported at the Mayo Clinic, Rochester, Minn, during the past 72 years. Jejunogastric intussusception is a difficult condition to diagnose clinically. Essentially all patients have epigastric pain. Patients with intussusception generally have had retrocolic gastrojejunostomy without gastric resection. Intussusception of the efferent limb of jejunum is the most frequent type. Surgery is indicated for all patients with the acute type, whereas the chronic type may or may not require operative intervention, depending on the severity of the symptoms. Confirming the diagnosis at operation is occasionally difficult because of spontaneous reduction. Symptoms may recur after operation, but documented recurrence is rare.
