Very Long Term Results After Laparoscopic Retrocolic Antegastric Gastric Bypass (>10yrsRYGB)
December 28, 2009 updated by: University of California, San Francisco
The main aim of this study is to analyze and report the very long-term outcomes after primary laparoscopic proximal Roux-en-Y gastric bypass surgery for clinically severe obesity.
Study Overview
Status
Completed
Conditions
Detailed Description
There is lack of very-long term outcomes after bariatric surgery; A few series have been reported.
However, most of them analyze medium-term outcomes.
For RYGB, there are just two retrospective cohort studies reporting very long-term outcomes.
Both studies have an open approach and a proximal Roux-en-Y configuration with different pouch orientation and size.
MacLean´s series, with a better follow-up rate (83.4%), had a 67.6%EWL at a mean of 11.4 years; Failure rates were 20 and 35% for the morbidly obese and super obese, respectively.
We will analyze our own series with a laparoscopic approach, vertically, lesser-curve base < 10-15ml pouch and proximal Roux limb.
The main end-points for our study are 1) Morbidity including status of specific biochemical markers & Mortality, 2) Weight loss expressed as BMI or %EWL, 3) Trends in major comorbidities and 4) Assessment of Quality of Life.

Study Population
Patients who had clinically severe obesity and underwent a primary laparoscopic Roux-en-Y Gastric Bypass more than years ago were identified form a prospectively maintained database at UCSF Fresno / ALSA med group, Inc Minimally Invasive Surgery Program.
Description

- follow up > 10.0 years (Very long term outcome)
Exclusion Criteria:
- patients who had a previous gastric or bariatric procedure
- patients who underwent primary laparoscopic RYGB somewhere else by other surgical group
- missing records and/or unreachable patients with scant information for analysis
