  Purpose

The purpose of this study is to determine the feasibility, safety, and efficacy of revision gastroplasty along with other adjunct procedures in the treatment of intractable / chronic marginal ulcers after Roux-en-Y gastric bypass. A secondary aim is the identification of good and poor outcome predictors after revisional strategies for intractable or chronic marginal ulcer.

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 ] [ Designated as safety issue: Yes ]
  • Weight loss expressed as Body Mass Index and Percentage excess weight loss [ Time Frame: at 6 months, 1 year and annually thereafter for up to 4 years ] [ Designated as safety issue: No ]
  • Remission or improvement of marginal ulcer-related symptoms [ Time Frame: at 6 months, 1 year and annually thereafter for up to 4 years ] [ Designated as safety issue: No ]
  • Remission or improvement of comorbidities [ Time Frame: at 6 months, 1 year and annually thereafter for up to 4 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
  • 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. ] [ Designated as safety issue: No ]

Groups/Cohorts
Chronic marginal ulcer after RYGB
Patients with intractable or chronic marginal ulcer disease after gastric bypass complaining of abdominal pain, GI bleeding, obstruction, perforation and penetration. Sometimes with other associated diagnosis such as narcotic and tobacco dependence, protein-calorie malnutrition, excessive weight loss, poor pouch emptying syndrome, weight regain, inadequate initial weight loss, severe dumping syndrome among others.
