title: Imaging findings in Roux-en-O and other misconstructions: rare but serious complications of Roux-en-Y gastric bypass surgery.
abstract: OBJECTIVE
  The purpose of this study was to present the clinical and imaging findings of Roux-en-O and other misconstructions of Roux-en-Y gastric bypass surgery. The more common complications of Roux-en-Y gastric bypass have been described in the literature. Complications secondary to misconstructions are rare and difficult to diagnose.
  
  
  CONCLUSIONS
  Roux-en-O or other misconstruction should be suspected in patients with chronic bilious vomiting after Roux-en-Y gastric bypass when no mechanical basis for obstruction can be identified. Fluoroscopic motility assessment is often critical in the diagnosis of these misconstructions.
