  • 2. Best Rx for Diabetes 5 Objectives 1. Consider Band/Sleeve/RNY/MGB 2. Best Rx DM Requires Gastric Procedure + Duodenal Bypass 3. Eliminates Band/Sleeve; Choice RNY vs MGB 4. RNY Most Technically Difficult Dangerous & Deadly form of Bariatric Surgery 5. Data MGB One of the Most Effective & Safest Rx for DM
  • 3. Objective 1: Consider Band/Sleeve/RNY/MGB
  • 4. Objective 2: Best Treatment of Diabetes Includes Both a Gastric Procedure + Duodenal Bypass Data from General Surgery, Bariatric Reports, Animal Studies
  • 5. Objective 2: Animal Models Confirm Duodenal Bypass Improves Effectiveness “This study shows that bypassing Duodenum Improves T2D, independently of food intake, body weight, malabsorption, or nutrient delivery” The Mechanism of Diabetes Control After Gastrointestinal Bypass Surgery Reveals a Role of the Proximal Small Intestine in the Pathophysiology of Type 2 Diabetes. Rubino,); Marescaux, Jacques MD, FRCS Annals of Surgery; 244 (5): 741-749, November 2006
  • 6. Objective 2: Billroth I vs Billroth II Gastrectomy vs Gastrectomy + Bypass Primary Gastric Procedure (PGP) Vs Combined Gastric + Bypass (CGB) Which Leads to Greater Weight Loss? Which Leads to Greater Resolution of Diabetes? General Surgery Answer:
  • 7. Bariatric Surgeons Should Not Forget Their General Surgery Training GS for Gastric Disease (Ca/Ulcer) Gastrectomy ALONE 50% Gastrectomy + Duodenal Bypass 75% Rx T2D MUST Include Duodenal Bypass for BEST short and long term Efficacy G.O. Less Effective G+D G.O.=Gastric Only vs G+D=Gastric + Duodenal
  • 8. Outcome after gastrectomy in gastric cancer patients with type 2 diabetes • 403 gastric cancer patients with T2DM • BMI % Reduction • Duodenal Bypass: • BI: No Bypass 7.6% • BII: Bypass 11.4% • ** 50% Improvement ** • Jong Won Kim, etal, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul 135- 720, South Korea, World J Gastroenterol. 2012 January 7; 18(1): 49–54.

  • 12. Gastrointestinal metabolic surgery for the treatment of diabetic patients (Lakadawala) 200 patients, Gastric Bypass vs Sleeve gastrectomy Remission of T2DM “Gastric Bypass pts (Gastric + Bypass) lost more weight & higher diabetes remission Sleeve pts“ Bypass pts mix of MGB/RNY (per Dr. Lee)
  • 13. Objective 2: MGB vs Sleeve Mini-Gastric bypass vs Sleeve Gastrectomy for type 2 diabetes mellitus: a Randomized Controlled TrialRandomized Controlled Trial Lee WJ, Chong K, Ser KH, Lee YC, Chen SC, Chen JC, Tsai MH, Chuang LM. Arch Surg. 2011 Feb
  • 14. Objective 2: Lee MGB vs Sleeve Randomized Controlled Trial Randomized controlled trial 60 moderately obese patients (body mass index >25 and <35) Outcome was remission of T2DM (fasting glucose <126 mg/dL and HbA(1c) <6.5% without glycemic therapy) All completed the 12-month follow-up
  • 15. Lee MGB vs Sleeve Randomized Controlled Trial Remission of Diabetes ** 93% ** Mini-gastric bypass ** 47% ** Sleeve gastrectomy (P = .02)
  • 16. Lee MGB vs Sleeve Randomized Controlled Trial Mini-gastric bypass lost more weight, achieved a lower waist circumference, and Lower glucose, HbA(1c), and blood lipid levels than the sleeve gastrectomy group
  • 17. Effectiveness of Bariatric Procedures Gastric + Duodenal Bypass Outperforms Gastric Alone G.O. Band Poor G.O. Sleeve Med High G+D RNY High G+D MGB High - Highest Conclusions Band & Sleeve Less Effective than RNY & MGB
  • 18. Objective 3: Best Rx DM Gastric Procedure + Duodenal Bypass This Excludes Band/Sleeve Need for Gastric Procedure +Bypass Eliminates Band/Sleeve; Leaves Choice RNY vs MGB

  • 38. Laparoscopic Roux-en-y Vs. Mini-gastric Bypass For The Treatment Of Morbid Obesity: A 10-year Experience. October 2001 and September 2010, 1,657 patients who received gastric bypass surgery (1,163 for LMGB and 494 for LRYGB) Surgical time was significantly longer for LRYGB (159.2 vs. 115.3 min for LMGB, p<0.001).    The major complication rate was higher for LRYGB (3.2 vs. 1.8%, p  =0.07).  5 years after surgery, the mean BMI was lower in LMGB than LRYGB (27.7 vs. 29.2, p<0.05) and    LMGB also had a higher excess weight loss than LRYGB (72.9 vs. 60.1%, p<0.05).    Late revision rate was LRYGB 3.6% and MGB 2.8%
  • 39. Laparoscopic Roux-en-y Vs. Mini-gastric Bypass For The Treatment Of Morbid Obesity: A 10-year Experience. CONCLUSIONS: This study demonstrates that MGB can be regarded as a SIMPLER and SAFER alternative to RNY with similar or BETTER efficacy at a 10- year experience.

  • 41. MGB More Effective than BPD Dr Tacchino MGB vs BPD Weight Loss and Diabetes Resolution Following Mini- Gastric Bypass and Bilio-Pancreatic Diversion. Tacchino R., Rutledge R., Università Cattolica del Sacro Cuore, Rome, Italy 408 pts Jan 2007 to Dec 2009 36 months follow-up Mini-Gastric Bypass (n = 164) initial BMI 46.4±9.6 or Bilio-Pancreatic Diversion (n = 244) initial BMI 46.9±7 (Tacchino’s perferred Operation)
  • 42. MGB More Effective than BPD Dr Tacchino MGB vs BPD RESULTS: Mean BMI at two years was 28.5±3.9 kg/m2 and at three years 27.4±4.5 kg/m2 after MGB BMI at two years 32.7± 6.04 kg/ m2 and at three years 33.6±5.1 kg/m2 after BPD One year resolution of diabetes was accomplished in: 100% in MGB group 95% in BPD group.
  • 43. MGB More Effective than BPD Dr Tacchino MGB vs BPD Tacchino’s conclusions: “Both MGB and BPD resluted in excellent weight loss, excellent resolution of co-morbities with low risk of long term complications. The MGB was associated with greater weight loss than BPD. Improvements in other cardiovascular risk factors and quality of life were similar after both procedures.”

  • 124. WHAT CAUSES GASTRIC CANCER? ITS NOT BILLROTH II • Diets rich in fried, salted, smoked or preserved foods increased cancer risk in many studies. • Foods contain nitrites and these chemicals can be converted to more harmful compounds (carcinogens) by bacteria in the stomach. • Diets high in fruit and vegetables protects against Cancer • Stomach cancer is much more common in smokers and in those with heavy alcohol intake. • H. Pylori, No H. Pylori No Cancer
  • 125. DIET AND CANCER PREVENTION • Avoid ETOH, Tobacco, Processed & Preserved Meats, Salt • RX H. Pylori, • Eat Fruits and Veggies, Yogurt and • Drink Green Tea • Gonzalez CA, Cancer Research, Institut Català d'Oncologia, Av. Gran Via s/n, km 2.7, 08907 L'Hospitalet, Barcelona, Spain.
