 |
| Anatomy |
An adjustable silicone ring (band) is placed around the top part of the stomach creating a small 15-30 ml pouch. |
Small 7-10 ml gastric pouch is connected to the small intestine bypassing the stomach. Food and digestive juices are separated for 3-5 feet. |
Most of the stomach is removed in a “vertical” fashion leaving a “banana” shaped stomach remnant. |
| Mechanism of Action |
Moderately restricts the volume and type of foods able to be eaten. Band diameter is is adjustable. Must be properly adjusted to create sensation of fullness |
Significantly restricts the volume of food that can be eaten. Mild malabsorption. “Dumping Syndrome” if wrong foods such as sugar or fats are eaten |
Somewhat restricts the volume of food that can be eaten. Also allows food to pass quickly down the gut. Removes the Ghrelin producing cells of the stomach. All these may reduce appetite. |
| What surgical approach is used for each surgery? |
Laparoscopic or minimally invasive (also called by some keyhole surgery) 4 small (7 mm) cuts and one larger (2 cm) cut to place the adjustment port under the skin. |
Laparoscopic or minimally invasive (also called by some keyhole surgery) 5 small (7 mm) cuts are used. No adjustment port therefore avoids the larger 2 cm skin cut. |

| What Weight Loss can I expect with each? |
50-60% of extra weight lost at 3 years (based on our own data) |
70-80% of extra weight lost at 5 years (based on our own data) |
~55% of extra weight lost at 3 years BUT LONG TERM RESULTS NOT AVAILABLE! |
| Diet-Life Style Changes Required |
Must consume less than 800 calories per day for 18-36 months, 1000-1200 thereafter. Certain foods can get “stuck” if eaten (rice, bread, dense meats, nuts, popcorn) causing pain and vomiting. No drinking with meal (can drink 30 min before and 45 min after) Must exercise (e.g. walk 10,000 steps per day using pedometer) |
Patients must consume less than 800 calories per day in the first 12-18 months; 1000-1200 thereafter 3 small high protein meals per day Must avoid sugar and fats to prevent “Dumping Syndrome” Vitamin deficiency/ protein deficiency usually preventable with supplements Must exercise (e.g. walk 10,000 steps per day using pedometer) |

| How Quickly will I lose the extra weight? |
Weight loss is gradual and may take up to 5 years. Some weight regain seen at this time. |
The lowest weight loss occurs at 2.5 years and followed by some weight regain and stabilization depending on patient compliance with diet and exercise. |
Most of the weight loss occurs within the 1-2 years after surgery. Some weight regain and stabilization occurs after depending on patient compliance with diet and exercise. If the weight loss is not adequate you may need to have a second surgery to convert the VSG to gastric bypass or the full duodenal switch. |

| What is the period of convalescence? |
Because this is minimally invasive surgery patients only need to convalesce for 1 – 2 weeks at home (some patients can return to desk jobs within 1 week of surgery) |

| Who pays for the Surgery? |

| Is the operation reversible? |
YES- Laparoscopic surgery can be done to remove the band. In some cases this can be difficult due to scarring that forms around the band. It is not recommended except in very unusual circumstances. Wait regain is almost a certainty. |
YES -Unlike what is stated on some web sites or what you hear from others, laparoscopic surgery can be done to join the new small gastric pouch to the main stomach, since this is not removed at the original surgery. It is not recommended except in very unusual circumstances. Wait regain is almost a certainty. |
NO- Once the stomach is removed it cannot be grafted back into the body. |
| Our Recommendations |
Best for patients with BMI=32 kg/m2 (with co-morbidity) up to 50 who enjoy participating in an exercise program and are more disciplined and can follow dietary restrictions. Some recent research indicates that is special circumstances patients with BMI as low as 30 may achieve health benefits from weight loss through laparoscopic band surgery. |
Most effective for patients with a BMI of >=35 (with co-morbidity) or >40 kg/m2 especially those with a “sweet-tooth”. It takes away the hunger and produces 10-15% more weight loss then AGBD. It is considered the “Gold Standard Procedure” for weight loss in North America. |
Best for patients with BMI=32 kg/m2 (with co-morbidity) up to 50 who enjoy participating in an exercise program and are more disciplined and can follow dietary restrictions. Since we have no data on long term weight loss maintenance, if the weight loss is not adequate you may need to have a second surgery to convert the VSG to gastric bypass or the full duodenal switch. |
| Final Note: |
THE LAPAROSCOPIC BAND MUST BE PROPERLY ADJUSTED TO ACHIEVE THE STATED BENEFITS. PATIENTS MUST MAKE THE COMMITMENT TO RETURN FOR ADJUSTMENTS AND REGULAR FOLLOW-UP. |
RYGBP DOES NOT REQUIRE FURTHER ADJUSTMENTS. PATIENTS MUST MAKE THE COMMITMENT TO RETURN FOR REGULAR FOLLOW-UP. |
VSG DOES NOT REQUIRE FURTHER ADJUSTMENTS. PATIENTS MUST MAKE THE COMMITMENT TO RETURN TO US OR THEIR HEALTH CARE PRACTITIONER FOR REGULAR FOLLOW-UP. |

I LOVE this COMPARISON section of the site ….BUT….I don’t know about the rest of you but I can’t see half of the text of the VGS section on the right hand side of my screen vertically from top to bottom…can I fix this???
Thks Nora for letting me know. The fix will be coming soon. (I have to re-format this page – fairly large job)
Ok – The comparison page should now display correctly
GREAT!!! Thank you so much!
Yeeeea Ron! Thank you so much for the quick response/fix!!
I am really glad to see this comparison chart. Now I feel confident that I have chosen the right type of surgery for me, Although I was told by Dr.Ambson that my surgery will be “open”, as I have had previous stomach surgery and he doesn’t know what to expect. I’m not looking forward to the open surgery….I wish it could be laproscopic. Oh well….I sit and wait for the glorious day that I get to have the surgery. TTYL.
Thank you for this very informative and useful comparison chart.
Even after having surgery I found this informative and interesting to learn about other surgeries as well.
The page still does not look okay for me…
And I am still not sure… RNY? VSG? which one should I take? I thought I knew!
