Gastrectomy for stomach cancer on type 2 diabetes (Kang)

• Conclusions:• Addition of foregut-bypass (MGB)• Improves the type 2 DM • better than Gastrectomy ALONE (Sleeve)• Diabetes remission is significantly higher

in those with duodenal bypass

• 75 GCa Pts, 35 month FU• BI vs BII for resolution/Improvement in DM• Gastrectomy ALONE (Sleeve)

0% Resolved, 45% improved• Gastrectomy + BII (MGB)

22% Resolved, 85% Improved

• The improvement rate of diabetes mellitus (DM) status was 7.46 times higher in B-II than in B-I patients.

• The method of reconstruction is the most powerful factor for the improvement of the disease after surgery

• To treat Diabetes• Gastrectomy alone • Much Worse than• Gastric + Bypass

• Remission of T2DM was achieved in 72.4% of the patients.

• “Individuals who underwent gastric bypass lost more weight & higher diabetes remission than sleeve pts“

• Bypass pts included mix of MGB and RNY (per Dr. Lee)

MGB More Effective than BPDDr Tacchino MGB vs BPD

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)

• 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.

• 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.”

RouxLimbMany Studies ofvarying roux limb lengths: 60 cm to 200 cm do not predict either absolute or excess weight loss

50-70% Gut Bypass has No Effect on Fat and Calorie Absorption or on Body Weight

Experimental Evaluation of the Nutritional Importance of

Proximal and Distal Small Intestine Kremen, et al.

Experimental studies in dogs reveal that animals can be deprived of from 50 to 70 per

cent of their small intestine and maintain a near normal nutritional status.

Experimental Evaluation of the Nutritional Importance of Proximal and Distal Small Intestine

• Study showed that after sacrifice of major lengths of the proximal small intestine,

• the animal's weight is satisfactorily maintained near preoperative levels, and

• no great interference with fat absorption is observed.

Note: Duodenum is Preserved

Massive bypass = No Effect

• The small intestine in adults is a long and narrow tube about 7 meters (23 feet) long

• 50% Bypass = 11.5 ft (3.5 meters)• Minimal Weight Loss!• WHEN DUODENUM IS PRESERVED

What if the Duodenum is Bypassed?

What is Roux-en-Y Gastric Bypass Surgery?

• Roux-en-Y Gastric Bypass (RYGB) combines both

• Restrictive and • Malabsorptive • Components

The contribution of malabsorption to the reduction in net energy absorption after long-limb Roux-en-Y gastric bypass

• Roux-en-Y gastric bypass (RYGB) restricts food intake, and

• when the Roux limb is elongated to 150 cm, the procedure is believed to induce malabsorption

• Objective measure reduction calories after RYGB

• Restriction of food intake vs Malabsorption

• The contribution of malabsorption to the reduction in net energy absorption after long-limb Roux-en-Y gastric bypass, Elizabeth A Odstrcil, et al. Am J Clin Nutr October 2010 vol. 92 no. 4 704-713

• No statistically significant effects of RYGB on

• Protein or • Carbohydrate

absorption coefficients

• 5 months after bypass, • Malabsorption reduced

absorption of combustible energy by 124 ± 57 kcal/d, whereas

• Restriction of food intake reduced energy absorption by 2062 ± 271 kcal/d

• In RNY Restriction 16 times more important than Malabsorption

• 14 months after bypass, • Malabsorption reduced

absorption of combustible energy by 172 ± 60 kcal/d, whereas

• Restriction of food intake reduced energy absorption by 1418 ± 171 kcal/d

• Restriction 8 times as important as Restriction

• (Why: Restriction Beginning to Fail)

• On average, malabsorption accounted for 6% and 11% of the total reduction in ccaloric intake at 5 and 14 mo, respectively, after 150 RNY gastric bypass

• RNY: Primarily a Restrictive Procedure

• NOTE: Early signs of failure
