Laparoscopic Gastric Bypass, also known as Roux-en-Y Gastric Bypass is one of the most effective operations done to lose excess weight, as it is a delicate laparoscopic operation through which the digestive pathway is anatomically and physiologically changed in a way that shortens the time food spends in the GI system, therefore reduces the absorption of calories, and enhances daytime satiety. Gastric bypass is characterized by the fact that it is difficult to re-gain the lost, in addition to the possibility of reversing the stomach back to its normal position after eliminating the excess weight.
Candidates for the Gastric Bypass Surgery
- Patients with a body mass index (BMI) above 40 or people with hypertension and diabetes with a BMI of more than 35.
- Patients who do not suffer from heart disease or blood clotting problems.
- Patients who suffer from diseases such as diabetes, osteoporosis, or joint pain due to excess weight.
- Those who wish to experience regular weight loss process over short period.
- Those who have not been able to lose weight through sports or dieting.
Prior to Gastric Bypass Surgery:
1. Eating and drinking must be stopped 12 hours before the Gastric Bypass Surgery.
2. Smoking must be stopped two weeks before the Gastric Bypass Surgery, preferably one month earlier.
3. Stop drinking alcoholic beverages two weeks before the Gastric Bypass Surgery.
4. It is preferable to stay away from caffeine a week before Gastric Bypass Surgery
5. Stop using blood-thinning medications or blood-thinning drinks such as green tea or ginger.
Stages of the rerouting process
• Gastric Bypass Surgery is performed under general anesthesia and is done by using a laparoscope in order to reduce pain and scars after the operation.
- Mini Gastric Bypass:
The surgeon separates the stomach into an upper part that resembles a narrow tube with and a lower part that is completely closed, through which food does not pass. The upper part of the stomach is attached to the small intestines; a process that aims at shortening the pathway of food from the stomach to the intestine and reducing the absorption of fats carbohydrates.
- Single Anastomosis Stomach–Ileal Bypass with Sleeve Gastrectomy (SASI-S)
The surgeon dissects the stomach longitudinally and divides it into two sections or two pathways:
- The first section or pathway is the functional section of the stomach where food passes naturally from the esophagus, and it mainly resembles a narrow tube.
- The second section or pathway extends from the stomach and connects to the small intestine, thus making the digestive system shorter and less effective in absorbing fats, sugars, and calories, thus achieving early satiety, and increasing the secretion of the satiety hormone.
There is no ideal bariatric surgery that goes along with all obsess patients. Rather, your best surgical option varies according to your medical case. Our team of doctors, medical consultants and translators cooperate to decide for you the most appropriate way to lose more weight on a regular and optimal basis.
We must note that Gastric Bypass Surgery in all its forms maintains good absorption of nutrients such as vitamins and minerals during the passage of food in the small intestine.
After Gastric Bypass Surgery
1. Rely on fluids during the first 10 days after the operation.
2. Adhere to a specific diet as shown in the image below.
3. Focus on drinking enough water.
4. Consult your doctor directly in cases of persistent pain lasting for a day or more.
5. Stay away from strenuous activities and sports in the first period after the operation.
What is the difference between SASI-S Gastric bypass and Mini Gastric Bypass Surgery?
The biggest difference between SASI-S Gastric Bypass and Mini Gastric Bypass Surgery is the time required to perform the operation, as Mini Gastric Bypass Surgery, it takes less time to perform the operation and gives almost the same result.
In Mini Gastric Bypass Surgery, a small part of the stomach remains like a pocket through which food passes, while in the process of SASI-S Gastric Bypass, the esophagus is connected almost directly to the intestine and the stomach does not have any role in the digestion process.
Frequently asked questions after gastric bypass surgery
• How long does the rerouting process take?
It takes 2 to 4 hours.
• Does gastric bypass have any benefits other than weight loss?
Yes, bypassing the process of balancing the blood sugar level in diabetic patients by increasing the response of the body cells to the hormone insulin, in addition to improving it for several diseases, including polycystic ovaries in women and metabolic syndrome.
Gastric bypass surgery also reduces pressure and swelling in the stomach wall, and this is enough to treat chronic reflux in the esophagus.
• Are there cases in which doctors do not recommend Gastric Bypass Surgery?
Gastric Bypass Surgery is not recommended for those who regularly take corticosteroids or pain relievers for autoimmune diseases, as well as for patients with inflammatory bowel diseases like Ulcerative Colitis or Crohn’s disease.
In cases of these patients, we recommend a Sleeve Gastrectomy instead of Gastric Bypass Operation.
• Does the weight return to the people who have undergone the bypass surgery?
Yes, if you do not follow a pre-planned diet after the operation and do not exercise regularly, it is possible to gain the weight again.
• Can Gastric Bypass Surgery be reversed?
Yes, the gastric bypass process can be reversed, and stomach can grow back to its previous position.
• Is the process of Gastric Bypass Surgery painful?
Gastric Bypass Surgery is a safe and painless process.
