The stomach is cut from the bottom of the esophagus, leaving 20-3ml of the stomach. Thus the stomach is divided into two parts, the small part takes the food and the large part remains unused.
In the next phase of the surgery, the small intestine is cut just below the duodenum. This creates a connection by pulling one end of the cut intestine towards the small stomach. The other end of the cut intestine is placed next to the small intestine and a second connection is made to give the intestine a Y-shape. Hence the operation is called Roux-Y gastric bypass.
During a bypass surgery the stomach is reduced to a smaller size and a part of the small intestine is skipped and connected with the stomach. This leads to an earlier feeling of satiety through eating less, as well as a bypass around the duodenum. This will reduce the intake of food and calories and this will lead to significant weight loss.
Gastric bypass is the most complex form of gastric surgery. The Roux-Y gastric bypass has been a popular weight loss surgery in the past. Today it is being replaced by other, less invasive operations.
The surgery is performed under general anesthesia using a laparoscopic (closed) technique. With the help of laparoscopic instruments, an incision of two centimeters is made in the abdomen, whereby a camera and instruments are placed and used. The stomach is separated by sewing and cutting at the same time with the help of tools like staplers and steel clamps.
Patients with a body mass index (BMI) of 40 and higher,
If the BMI is between 35 and 39.9 and a serious health problem (type 2 diabetes, high blood pressure, severe sleep apnea, etc.) exists.
If your obesity has emerged from excessive alcohol consumption or sugary foods, we may recommend gastric bypass surgery.
Dr. Aynacı does not prefer to perform the surgery on the day the patient arrives. The surgery is performed the following day. After the patient is taken to the operating room, it takes 30 minutes that the patient falls asleep with the help of the general anesthesia and that the surgical materials and positioning are prepared. Dr. Aynacı can only start the operation after 30 minutes. The surgery itself takes an average of 90-120 minutes. The patient takes about 15 minutes to wake up. The total duration of the surgery is 3 hours. When the surgery is over, the patient wakes up in a single room, where professional staff will take care of them in the best possible way.
There are generally always risks involved in surgical interventions. However, obesity surgery itself is not particularly dangerous. Information about the techniques used, the materials used, and the general health of the patient will reduce the risk of surgery. Dr. Aynacı uses all tools and materials only once. The material used is from Medtronic (Covidien) and is made in America.
In rare cases, intestinal blockages due to damage to important organs or vessels, bleeding, infections from internal or external wounds, peritonitis, leakage from anastomoses, stenoses, wound healing problems, dumping syndrome, thrombosis and embolism, gastrointestinal disorders, allergies and internal hernias can occur.
First and foremost, gastric bypass is not a reversible procedure if you should you regret the surgery later. In other words, you should be aware that it is a permanent surgery. Because of this, it is necessary to think carefully before the surgery.
It is important to note that gastric bypass surgery gives the stomach and intestines a short time and space to absorb fat and nutrients. You should take vitamin and mineral supplements daily for the rest of your life as fewer vitamins and minerals can be absorbed.
However, you will definitely lose weight after the surgery and have a much better quality of life regarding the activities you could do with difficulty before the surgery.
In the first six months after the surgery, it is important to be careful about food intake and not to drink alcohol, as the patient may experience slight abdominal pressure, which can lead to mild discomfort.
You may also suffer from flatulence or diarrhea. In rare cases, reactive hypoglycemia can occur after eating or drinking too much sugary foodstuff.
