  6. Evolution After a careful pre-operatory evaluation, he is taken for a gastric bypass surgery His work up included: CBC, CMP, PT, PTT Abdominal ultrasound Echocardiogram Polysomnography

  7. Surgery At the operatory time, cirrhosis is found incidentally The surgeon decides to do a vertical banded gastroplasty instead of the GBP Liver biopsy taken Post operatory uneventful

  8. VERTICAL BANDED GASTROPLASTY Stomach stapling Restrictive surgery Plastic Band Small pouch Normal absorption Failure in 25-50% patients

  10. Post Op Mr. W lost 100 lb during the first 6 months His DM, BP, lipids, back pain improved He then started to drink high caloric liquids Gained 60 lbs back GBP was then scheduled

  11. Gastric Bypass Stomach is stapled Roux-en-Y Restrictive and malabsorptive Low incidence of hepatic complications More consistent weight loss

  12. Second surgery biopsy
