Laparoscopic Adjustable Gastric Banding |
|
Roux-en-Y Gastric Bypass |
|
|
|
| How is the surgery done? |
An adjustable silicone ring (band) is placed around the top part of the stomach creating a small 15-30 ml pouch. |
|
A small 15-30 ml gastric pouch is connected to the small intestine bypassing the stomach allowing food and digestive juices to be separated for 3-4 feet. |
How does it work? |
Moderately restricts the amount and type of foods that can be eaten.
Band diameter is adjustable and must be properly adjusted to create a sensation of fullness. |
|
Significantly restricts the volume of food that can be eaten.
Some “malabsorption” will occur because of the bypassed portion of the small intestine.
"Dumping Syndrome" may be experienced if the wrong foods such as sugar or fats are eaten. |
What type of surgical approach is used? |
Laparoscopic (i.e. minimally invasive) consisting of 4 small (5-7 mm) cuts and one larger (2 cm) cut to place the band adjustment port under the skin. |
|
Laparoscopic (i.e. minimally invasive) in which 6 small (5-7 mm) cuts are used.
-Or-
Open approach in which a traditional mid-line abdominal cut is used. |
How much weight can I expect to lose? |
50-60% of extra weight lost at 3 years (based on our own data). |
|
60-100% of extra weight lost at 5 years.
The average weight loss is 65% of the excess (based on our own data). |
What diet lifestyle changes are required? |
Patients must consume less than 800 calories per day for 18-36 months, 1000-1200 thereafter.
Certain foods can get "stuck" if eaten (e.g. rice, bread, dense meats, nuts, popcorn, etc.) 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.
Must include 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). |
What lifetime nutritional supplements will I need? |
Multivitamin
Calcium |

Multivitamin
Vitamin B12

How quickly will I lose the extra weight? |
Weight loss is gradual and may take up to 5 years.
After weight loss some weight regain will be experienced. |
|
Patients will experience rapid weight loss in the first few months.
Around the one to one and a half year mark the weight loss will plateau off.
The weight loss is often followed by some weight regain and stabilization depending on patient compliance with diet and exercise. |
How long will I be in the operating room? |
55 min. (Avg.) |
|
70 min. (Avg.) |
How long will I need to stay in the hospital? |
Overnight (24 h) |
|
2 days (48 h) |
When can I return to work? |
Not until your surgeon says it is ok but some patients can return to desk jobs within 2 weeks of 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.
Weight 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.
Weight regain is almost a certainty. |
What operation is best for me? |
Best for patients with a Body Mass Index (BMI) of 35 (with comorbidity) up to 50 who enjoy participating in an exercise program and are more disciplined and can follow dietary restrictions.
Some recent research indicates that in 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 comorbidity) or >40 especially those with a "sweet-tooth".
It takes away the hunger and produces 10-15% more weight loss then Adjustable Gastric Banding.
It is considered the "Gold Standard Procedure" for weight loss in North America. |
