MINI GASTRIC BYPASS
(ONE ANASTOMOSIS GASTRIC BYPASS)
The One Anastomosis Gastric Bypass (OAGB), also known as “mini gastric bypass”.
This procedure is fast becoming the procedure of choice. The reason for this is that this procedure is slightly less invasive than the Gastric Bypass (RYGBP), weight loss results are similar to the (RYGBP) and it is more effective than the Gastric Sleeve as it has additional element of partial malabsorption
The Mini Gastric bypass is a minimally invasive procedure carried out under a general anaesthetic via key hole surgery (small incision sites)
This weight loss is achieved though both the restrictive and malapsorptive element of this procedure. The restrictive part of the procedure is the stomach pouch which gives patients portion control as the pouch can only accommodate small quantities of food.
BENEFITS OF MINI GASTRIC BYPASS
The substantial weight loss achieved can lead to a dramatic improvement or complete remission of many of the weight related health issues associated with obesity.
IMPROVED HEALTH & OBESITY RELATED ILLNESSES
The first stage reduces the size for the stomach by separating a tube like pouch of stomach from the remaining stomach similar to the Gastric Sleeve procedure.
- Key hole surgery with 5 small (1 inch) incisions site on the torso.
- The first stage is where the stomach is divided into 2 parts. One part, a long narrow tube that will serve as your new “mini-stomach”. The larger remaining part of is now
- The second stage is to bypass the small intestine: The length of small intestine that is bypassed will be determined by your surgeon and will be based on your starting BMI and medical history
- The final stage is when the small intestine is connected to the pouch creating the “bypass”., the malabsorptive element of the procedure.
Mini Gastric Bypass FAQs
Q: What is the difference between a mini gastric bypass and normal gastric bypass?
A: The difference between a mini gastric bypass (OAGB) and Gastric Bypass (RYGBP) is that the mini version of the surgery is performed in a modified manner that involves less intestinal rerouting and a shorter overall surgery time, resulting in lower complications rates.
Q: Can I drink alcohol and smoke after mini gastric bypass surgery?
A: Patients are advised to stop smoking prior to surgery and should also be aware that there are complications that can arise associated with smoking after surgery. Smokers are at a much higher risk of gastric pouch ulcers which can cause significant pain in the upper abdomen.
With regards to alcohol, patients are advised to avoid drinking alcohol for at least six months after surgery, there are several reasons for this. Alcohol could irritate the stomach as it is healing. You will become intoxicated a lot faster and the calories in alcohol with interfere with weight loss. You may also develop dumping syndrome which is marked by the rapid emptying of the stomach. The moral of the story is alcohol in moderation.
Q: What is dumping syndrome?
A: Dumping syndrome (rapid gastric emptying) normally occurs when alcohol or food, especially sugar moves from your stomach to your small bowel too quickly.
Symptoms of dumping syndrome generally occur right after eating especially if you have eating something rich in sucrose or fructose. Patients can experience a feeling of light-headedness, nausea, with raised temperature and rapid heart rate. Late dumping can also be experience which occurs one to three hours after sugar consumption. This is due to your body releasing large amounts of insulin to absorb the sugars entering your small intestine. The result is low blood sugar.
You can help to prevent dumping syndrome by dietary changes to reduce the intake of high sugar foods.
Q: What are the advantages of a mini gastric bypass?
A: Better weight loss then with a purely restricted procedure The OAGB typically results in a 60 – 80% weight loss.
The most rapid weight loss occurs in the first 6 months and then continues at a slower pace for up to another 18 months.
The malabsorptive element is achieved by bypassing a sizeable segment of the intestine the portion of intestine that the food travels through is not long enough for normal absorption of nutrients to occur.
Rapid improvement or resolution of weight related co morbidities
Less invasive than the RYGBP resulting in lower complication rates
Q: What are the disadvantages of the mini gastric bypass?
A: It is a slightly more complex procedure than the gastric band or gastric sleeve although complication rates are low.
Could lead to long-term vitamin/mineral deficiencies including vitamin B12, iron, calcium and folate
Requires adherence to dietary recommendations, patient compliance and life-long vitamin/mineral supplements.
