title: [Retrograde intussusception posterior to gastrojejunal anastomosis. Report of a case].
abstract: OBJECTIVE
  We report a case of retrograde jejunogastric intussusception in a patient with previous gastric surgery who required surgical treatment for its resolution.
  
  
  BACKGROUND
  While intussusception is relatively common in children, it is infrequently seen in adults. Five percent of all cases occur in adults and in 90% of these, there is a lead point, a well-definable pathologic abnormality. Retrograde jejunogastric intussusception is a rare complication after gastrojejunostomy. The most common symptoms are pain, nausea, vomiting and blood per rectum. Diagnosis of adult intussusception is often difficult and is base in clinical suspicion and noninvasive techniques.
  
  
  METHODS
  A case of a retrograde intussusception in a patient after gastric surgery who presented with abdominal pain and gastrointestinal bleeding.
  
  
  RESULTS
  The patient underwent surgical treatment with reduction of the intussusception. The postoperative evolution was satisfactory.
  
  
  CONCLUSIONS
  Management of intussuception in adults is usually laparotomy and in 90% of cases, a pathologic lesion will be identified. Retrograde jejunogastric intussusception is also managed surgically and simple reduction is the accepted form of treatment in most cases.
