Morbid Obesity Clinical Trial
Official title:
The Impact of Gastric Bypass on Gastroesophageal Reflux Disease in Patients With Morbid Obesity: a Prospective Study Based on Montreal Consensus
The hypothesis of this study was that gastric bypass (GBP) ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients.
The investigators studied the impact of this surgical procedure on GERD in patients with
morbid obesity.
Esophageal syndromes were evaluated according to the Montreal Consensus, where troublesome
symptoms were defined as score ≥ 2 on a validated questionnaire of symptoms for Portuguese
language along with esophageal syndromes with injury assessed through upper endoscopy.
Esophageal acid exposure was determined through 24h pH monitoring. Increased acid exposure
was characterized when total esophageal pH < 4 for at least 4% of the total monitoring time.
