Gastric Bypass

Pre-Operations Tests

Before the procedure, radiologic scanning tests, blood and hormonal tests might be demanded.

Operation Details

There are two steps during gastric bypass surgery.

At the first step the stomach is reduced in volume by creating a small pouch at the top of the stomach using surgical staples. The resulting pouch is only about the size of a walnut and can hold about one ounce (about 29 grams) of food thus decreasing the amount of food the patient can take.

At the second step, after the pouch has been created, most of the stomach and part of the intestines are bypassed by attaching (usually stapling) part of the intestine to the small stomach pouch. So the absorption of nutrients is reduced because the length of the path in small intestine has been shortened. As a result, the patient will absorb fewer calories.

This surgery is performed generally laparoscopic. The surgeon will make 4 to 6 small cuts in patient’s belly. One of this cut is used for the surgeon passes the laparoscope and the rest of these cuts will be used for other instruments’ insertion to do gastric bypass surgery.

After the procedure, control examination is required every month. Patients must supplement their diet with a daily multivitamin, calcium, B12 and/or iron.

Operation time, Hospitalization and Total Stay in Country

Operation time for this surgery is 3-5 hours. 4-5 days of hospitalization is required. After the discharge, the patient should stay for 7 days in country for doctor controls.
