How is Gastric Bypass (RYGB) operation performed?
Laparoscopic Gastric By-Pass (R-YGB) surgery is the most commonly performed surgical procedure of the combined type surgeries. You should know that Gastric Bypass is one of the methods that attract attention with its successful results in obesity surgery. With this surgery, the stomach volume is reduced, while the absorption of nutrients is reduced because the path traveled in the small intestine is shortened.
In the beginning part of our stomach, approximately 30-50 cc separation is made. Most importantly, a part of the small intestines is connected to the newly formed small stomach, which cannot be bypassed. Thus, patients experience a feeling of fullness quickly with a much smaller meal portion. At the same time, the absorption of a significant part of the high-calorie foods taken ends.
More effective and permanent weight loss is experienced with Laparoscopic Gastric By-Pass operation. Similar to volume-restricting surgeries, patients experience a feeling of rapid satiety with much smaller portions due to the reduced new stomach pouches.
Gastric By-Pass surgery can be recycled when necessary
Gastric By-Pass (R-YGB) is primarily a morbid obesity procedure. Gastric By-Pass (R-YGB) treatment can be performed in the presence of many diseases accompanying obesity. In particular, we can define it as Type 2 diabetes. Positive results are seen with gastric bypass surgery in the surgical treatment of Type 2 diabetes patients who cannot be controlled.
Before Gastric By-Pass operation
Persons who are planned to have an operation undergo a detailed evaluation. In addition to physical examinations, each patient should be evaluated in detail before the operation by endocrinology and psychiatry specialists.
How is the operation performed?
Gastric By-Pass is performed by laparoscopic method. In recent years, you can consider robotic surgery as a choice. 1 cm. Surgery is performed through 4-6 holes in diameter.
In gastric bypass surgery, the stomach diameter is reduced, just like in sleeve gastrectomy surgery. Approximately 95% of the stomach is bypassed.
A part of the stomach, which is divided into two by surgical methods, is placed in the middle of the intestine by bypassing the 12 finger intestines. In the other part, it constitutes its duty by not being removed from the body. In this way, the food consumed is prevented from passing through the 12 finger intestines. With the operation, it is aimed to saturate the patients with less food and to ensure that some of the food they take is absorbed.
The patients are followed up in the hospital for 4-6 days. At discharge, the nutrition program until the first control is adjusted by the dietitian. During the first year, he is followed closely by an endocrinologist, psychiatrist and dietitian apart from the bariatric surgeon.
What are the Gastric Bypass Types?
Roux en Y Gastric Bypass: In the operation, it is seen that the stomach is divided into two with a special stapler tool, leaving a stomach volume of approximately 25-30 cc from the point where the stomach meets the esophagus.
Here, a small stomach pouch and the other part of the stomach remain. thus, a connection is established between the small intestine and the small stomach pouch by forming a stoma.
The new connection between this pouch and the small intestine is known as the Roux en Y-arm.In this way, the food coming from your esophagus bypasses the entire stomach and the first part of the small intestine. In the Small Gastric Bypass procedure, the stomach becomes a tube by using special stapler tools. This newly created stomach pouch will be much larger than the Roux en Y type. Then, the small intestine segment is connected with this newly formed stomach pouch from a distance of about 200 cm.
The most important difference from the Roux en Y type is that it is technically easier and has a single connection. The weight loss mechanism is similar in both gastric bypass types.
Is there a risk of Gastric Bypass surgery?
Bleeding, infection, postoperative ileus (intestinal obstruction), hernia (hernia) and general anesthesia complications are seen in this procedure, which can also be seen in many other abdominal surgeries.
The most serious risk is leakage (leakage) that may occur in the connection between the stomach and the small intestine and a second surgical procedure that may occur as a result.
You should be aware that some additional surgical risks increase in addition to obesity.
10-15% of patients undergoing this surgery experience some of the above complications. In general, more serious complications are rare and common ones are acceptable and treatable.
Who is suitable for Gastric By-Pass surgery?
Obesity operations are planned according to the mass index of your body. Patients with a body mass index of 40 and above, or patients with a body mass index of 35-40 and who have medical problems such as obesity-related type 2 diabetes, hypertension, sleep apnea are suitable for this surgery.
After Gastric By-Pass surgery
After the procedure, you only have to be hospitalized for three or four days.
Heavy lifting after Gastric By-Pass
Care should be taken not to do heavy activities after discharge from the hospital. Not lifting heavy loads for 6 weeks.
