Laparoscopic Roux-en-Y Gastric Bypass (Gastric Bypass)
How does the Gastric Bypass work?
A small gastric pouch is created from the upper portion of the stomach. The stomach is reduced from the size of a football to the size of a golf ball. The pouch “new smaller stomach” is attached to the middle of the small intestine with a limb of intestine that has bypassed where digestive enzymes are secreted. This in effect both limits the amount of food consumed and the length of absorption affecting overall calorie intake.
How is the Gastric Bypass performed?
The Gastric Bypass is performed laparoscopically through small incisions. We staple and divide the stomach, creating a smaller pouch. The small intestine is then divided and rerouted in order to create our bypassed limb. The new connections “ anastomosis “ between stomach pouch and small bowel (so called G-J anastomosis) and between two loops of small bowel (so called J-J anastomosis) are both stapled and sutured. The anastomosis is tested with the help of intra-operative esophagogastroscopy.
What are the advantages of the Gastric Bypass?
- 60 to 80 percent excess weight loss
- Restrictive and mal-absorptive procedure
- Increase energy expenditure
What are the disadvantages of the Gastric Bypass?
- More complex operation with greater complication rates
- Can lead to long-term vitamin/mineral deficiencies requiring lifelong supplementation
- Longer hospital stay
What you will experience the day of surgery at
St. Vincent’s Medical Center
On the day of your procedure you will go to the surgery center. You are prepared for surgery and an IV will be put in place at this time. You will be transferred to the holding area to meet your surgeon, your anesthesiologist and OR staff taking care of you. In the OR you will be put asleep after inhaling oxygen enriched air via face mask by intravenously fast acting medication.
After surgery you will be transferred to the recovery room. If you have a history of sleep apnea you will receive extra monitoring at this time.
After you completely awake you may proceed to the nursing floor or to the intensive care unit. Placement in the ICU doesn’t mean that there is a surgical complication – it is usually for a patient who needs very close monitoring due to medical conditions that were present before surgery.
Pain after surgery is controlled by Patient Controlled Analgesia (PCA). This is a computerized pump that allows you to request and receive pain medication whenever you might want it. It is very safe and effective in controlling pain.
A swallow test is performed the next day after surgery. You will be asked to drink a small cup of clear liquid x-ray dye. This test helps us to confirm proper placement of the band.
After the swallow study you will be offered sugar free liquids and diet popsicles.
