Gastric Bypass After Previous Anti-reflux Surgery (RYGBafterARS)

This study has been completed.

The goal of this study is to describe the clinical presentation, indications, and operative treatment as well as assess the morbidity, mortality, and overall performance of revisional Roux-en-Y gastric bypass (RYGB) after either failed or functional antireflux surgery "ARS" in obese patients. With such information, we hope to determine which features might assist us in advancing our knowledge about Gastro-Esophageal Reflux Disease "GERD", the best option for primary ARS, and mechanisms of failure in the obese population as well as in identifying predictors of outcome after revisional surgery in this population.

Primary Outcome Measures:
  • Morbidity and mortality [ Time Frame: at discharge, 1 week, 3 weeks, 8 weeks, 3 months, 6 months, 1 year and annually thereafter for up to 4 years ]
  • Remission or improvement of GERD-related symptoms [ Time Frame: 6 months, 1 year and annually thereafter for up to 4 years ]
  • Weight loss expressed as Body Mass Index and Percentage of excess weight loss [ Time Frame: 6 months, 1 year, and annually thereafter for up to 4 years ]

Secondary Outcome Measures:
  • Remission or improvement of comorbidities [ Time Frame: 6 months, 1 year, and annually thereafter for up to 4 years ]
  • Length of operative time which is defined as the time duration of operation measured in minutes from the first skin incision to the final closure of the skin incision [ Time Frame: It is measured in minutes from the first skin incision to the final closure of the skin incision at the time of revisional surgery under study. It is a transoperative measure of outcome of the surgery under study ]
  • Length of Hospital Stay which is a measured of surgical recovery quantified and reported in days. It is a hospital pre-discharge traditional measure of outcome. [ Time Frame: It is measured in days from the admission date to the discharge date for the hospitalization pertaining to revisional surgery under study ]
