YANEZ M, RICARDO et al. Initial human experience with a restrictive, duodenal-jejunal by-pass liner for the treatment of morbid obesity. Rev Chil Cir [online]. 2010, vol.62, n.3, pp.234-239. ISSN 0718-4026.

Background: The EndoBarrierTM Gastrointestinal Liner creates an endoscopic duodenal-jejunal bypass leading to weight loss in morbidly obese patients. Aim: To evaluate the safety and efficacy of the EndoBarri-erTM with a 4 mm restrictor in morbidly obese patients. Material and Methods: Ten obese patients aged 18 to 54 years (eight women) with a body mass index (BMI) ranging from 35.8 to 45 kg/m2 were enrolled. Patients were followed for 12 weeks after the placement of the device, when it was removed. Outcomes measured were percent excess weight loss (%EWL), minor and major adverse events. Results: The mean implant time was 33 ± 4 minutes with a mean fl uoroscopy time of 14.8 ± 3 minutes. There were no major adverse events. Periodic episodes of nausea and vomiting lead to the endoscopic dilation of the restrictor hole with a 6 mm balloon between 2nd and 8th weeks in seven patients (70%). One subject required a second dilation with a 10 mm balloon. The device was endoscopically removed at the 12th week in all patients. The mean removal time was 47 ± 53.8 minutes (range 10-155 minutes). At week 12, BMI decreased from 40 ± 3.9 to 34.5 ± 3.1 kg/m2, and %EWL was 39.8% (range, 21.7% - 65.3%). The mean total weight loss was 16.7 ± 4.4 kg. Conclusions: The EndoBarrierTM Gastrointestinal Liner with the addition of a duodenal restrictor is a safe and effective short-term treatment for morbidly obese patients.
