Rny gastric bypass is a type of obesity and Metabolic Surgery in which a small part of the stomach is formed in the form of a small pouch and this newly created pouch is directly attached to the small intestine. After Rny gastric bypass, the food eaten will pass directly from this small pocket of the stomach directly to the intestines, so that most of the stomach and the first parts of the small intestine will be bypassed. It is one of the most performed surgeries in the world and is one of the oldest known surgeries. Gastric bypass will allow you to achieve your health in cases where you cannot control weight with diet or exercise, or have serious health problems associated with weight. In laparoscopic operations, surgical instruments are passed through small incisions through trocars. Patients have a much smaller wound that allows for a faster recovery time than traditional surgery. These small wounds have a lower risk of infection and hernia formation. Laparoscopic surgery also protects the patient’s immune function. Rny gastric bypass In Turkey is performed in accordance with European standards and provides excellent results.

What is Rny gastric bypass?

It is one of the most commonly performed bariatric surgery operations in the world. Rny Gastric Bypass, known as gastric bypass surgery, is one of the most common bariatric surgery operations in the world. Laparoscopic (Closed System) Method, stomach is reduced by stapler method. In this way, reduction in nutrient absorption occurs. Appetite is greatly reduced. The stomach is cut from the bottom of the esophagus so that 30-50 cc of the stomach remains. In this way, the future of food is divided into a small stomach bag and a large unused stomach bag. Then the small intestines are cut from 40-60 CM and the lower end is attached to the small gastric pouch. The upper end from the large blind gastric bag, where bile and pancreatic secretion are present, is attached somewhere in the middle of the small intestine, which connects to the new small stomach.

Rny gastric Bypass surgery is a surgical method that has been used for many years as the most popular surgery of obesity surgery. The process has two components. First, the stomach is divided in half so that it is close to the upper part. The stomach sac, which remains on top and through which food will pass, is left in a volume of about 30 milliliters. Next, the first part of the small intestine is divided, and the lower end of the divided small intestine is attached to the newly created small gastric sac. The upper part of the divided small intestine is also connected about 150-200 cm ahead of the small intestine, allowing stomach acids, bile and pancreatic fluids and digestive enzymes contained in them to encounter food in a more advanced part of the small intestine. Rny gastric bypass works by various mechanisms. Food does not enter the lower part of the stomach. The patient can eat in small quantities, and the resulting tension creates a feeling of satiety. Second, patients feel less hunger because the part of the stomach that secretes hunger hormones is disabled. Third, because digestive enzymes encounter food in the middle of the small intestine, there is less absorption. Less of the foods eaten participate in digestion.

Rny gastric bypass surgery is performed laparoscopically. In laparoscopy, from small incisions opened from the abdomen to the abdominal cavity, various instruments and a camera are placed in the abdomen for monitoring purposes. The image obtained by the camera is projected onto a screen, so the surgeon can perform the operation by watching it smoothly. The operation has 2 stages. In the first stage, a large part of the stomach is closed and cut and separated so that a little stomach is left in the part of the stomach that merges with the esophagus. In this way, a small gastric bag is created. The remaining stomach volume is approximately 30-50 ML. Unlike tube stomach surgery, no part of the stomach is removed in this operation. Thanks to the created stomach bag, nutrients now come here. In the second stage, a part of the small intestine is separated and connected to the stomach sac. In this way, a new digestive tract is created. During surgery, no parts of the body are removed. The separated parts of the stomach and intestines are attached to the created path after a place, helping bile and various enzymes participate in digestion. Since no parts of the body have been removed, it is possible that the digestive system can be restored to its former state. There is also a variation of the operation in which the intestines are directly joined with the stomach bag without dividing at all.

What are the advantages of Rny gastric bypass?

Here are some advantages of Rny gastric bypass:

  • A patient whose stomach has been reduced by RNY gastric Bypass surgery can consume smaller portions, but with these small portions, they can eat without feeling hungry.
  • Rny Gastric Bypass also reduces the absorption rate of consumed foods.
  • After surgery, the level of the appetite hormone, called the ghrelin hormone, drops, and the patient’s appetite is clearly reduced.
  • The patient gets rid of a large part of their excess weight in the long term (between 60-80%)
  • Reduced amount of absorbed food
  • Some of the appetite is more easily suppressed by creating a feeling of satiety
  • A large part of the weight given after gastric bypass surgery is usually permanent
  • It creates a sharper and more permanent solution to Type 2 diabetes and other related diseases.
  • The probability of gaining weight back is lower than in a tube stomach operation.
  • No liquid feeding period after the operation.

What are the risks of Rny gastric bypass?

Here are the most common risks of Rny gastric bypass:

  • In addition to limiting nutrient intake, Rny gastric bypass surgery reduces intestinal absorption of nutrients, resulting in weight loss; instead of following the usual path, food bypasses part of the stomach and the front of the small intestine. With sugar consumption, Dumping syndrome can also occur, which is manifested by abdominal cramps and diarrhea. Excessive fatty and fatty foods may also not be well tolerated. Weight gain in later years can occur, especially when post-operative recommendations are not observed.
  • The reported risk for Rny gastric bypass surgery is the same as the risk of any surgery in an obese patient. There is a risk of death of 0.5% and below. These risks and complications are reduced by the experience of the surgeon. Surgical complications such as bleeding or intestinal leakage can occur in less than 2% of patients. Detailed sharing of the risks of surgery with you before surgery should be part of your preoperative conversation with your surgeon.
  • Technically, it is a more difficult type of operation for the surgeon.
  • Especially in patients who consume cigarettes, the formation of stomach ulcers is more common
  • They are more likely to encounter Dumping syndrome.

How is the recovery period after Rny gastric bypass?

Although the healing process after RNY gastric Bypass surgery is not a very fast process, it is a process that can be easily avoided if you follow the doctor’s recommendations. In addition, there are different recovery periods depending on the condition of open surgery or closed surgery. After Rny gastric Bypass surgery, nutrition is the most important issue.

Is RNY gastric bypass reversible?

Although it is known that one of the advantages of Gastric Bypass over other obesity surgeries is that it is also reversible, in practice it is very rare to perform it. Because this reversible surgery is an operation that has very high complication and risk rates and most surgeons cannot do, and most of them will not want to do. Although gastric bypass surgery is also said to be reversible, it is technically a difficult conversion surgery that not every surgeon can or wants to do with a very high risk and complication rate.
