title: Safety experience with the duodenal-jejunal bypass liner: an endoscopic treatment for diabetes and obesity.
abstract: BACKGROUND
  The duodenal-jejunal bypass liner (DJBL) is a new, device-based endoscopic treatment for type 2 diabetes mellitus (T2DM) and obesity.
  
  
  OBJECTIVE
  To report serious safety events of subjects treated with the DJBL while offering a simple guideline to mitigate risk.
  
  
  METHODS
  Single-center observational study.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  For commercial use, patients were eligible for implantation of the DJBL when they met the following criteria: age 18 to 65 years, body mass index 28 to 45 kg/m(2), T2DM, and negative serum Helicobacter pylori test.
  
  
  METHODS
  Endoscopic implantation of the DJBL.
  
  
  METHODS
  Adverse events, serious adverse events, early explantation.
  
  
  RESULTS
  Between October 2007 and January 2014, 152 of 165 planned implantations (92%) and 94 explantations were performed in our center. Significant weight loss and improvement in T2DM and other cardiovascular parameters were achieved. Early removal of the device occurred because of persistent GI symptoms in 16 patients (11%). Serious adverse events were observed in a subset of patients: 7 GI bleeds, 5 of which required early removal; 2 cases of pancreatitis; 1 case of hepatic abscess; and 1 obstruction of the sleeve. Explantation resulted in an esophageal tear in 2 cases.
  
  
  CONCLUSIONS
  Single-center study.
  
  
  CONCLUSIONS
  The DJBL improves glycemic control while causing weight loss. The safety profile of the DJBL demonstrates a reasonable tolerability profile. However, serious safety adverse events can occur. Patient selection, expert use of the device at placement and removal, and the supportive care of an experienced multidisciplinary team are key for safe and effective use of the DJBL.
