title: Double-contrast barium enteroclysis as a patency tool for nonsteroidal anti-inflammatory drug-induced enteropathy.
abstract: BACKGROUND
  Evaluating small bowel patency is recommended for capsule endoscopy in patients suspected of nonsteroidal anti-inflammatory drug-induced (NSAID) enteropathy.
  
  
  OBJECTIVE
  The aim of this investigation was to examine whether radiography is a candidate of patency tool in NSAID enteropathy.
  
  
  METHODS
  We reviewed double-contrast barium enteroclysis in 21 patients with NSAID enteropathy diagnosed either by capsule endoscopy or balloon-assisted endoscopy. The endoscopic findings were classified into circular ulcers, linear ulcers and small mucosal defects. The radiographic signs of the corresponding endoscopic findings were retrieved and the depiction rate was calculated.
  
  
  RESULTS
  Of the 21 patients, endoscopy detected circular ulcers, linear ulcers, and small ulcers in 12, 3 and 12 patients, respectively. Small bowel radiography depicted circular narrowing as pseudo-folds in 10 patients (83%) and linear ulcers as eccentric rigidity in 2 patients (67%). However, radiography was able to depict small mucosal defects in only 3 patients (17%). Two of 5 patients with pseudo-folds experienced retention of the capsule.
  
  
  CONCLUSIONS
  "Pseudo-folds" is a sign corresponding to circular ulcer in NSAID enteropathy, which may be predictive of capsule retention.
