RNY Gastric Bypass is a type of bariatric surgery. It was previously performed as the first option in the surgical treatment of morbid obesity. However, as new methods became available, it turned into an alternative bariatric surgery technique applied only to necessary patients.
What is RNY Gastric Bypass?
RNY gastric bypass functions with its restrictive effect due to the shrinkage of the stomach. In addition to stomach reduction, it has an absorption-reducing effect as a result of the passage of nutrients from the shrinking stomach directly to the small intestines.
How is RNY Gastric Bypass Performed?
RNY gastric bypass is applied laparoscopically, that is, with closed technique. First of all, a small stomach pocket with a volume of approximately 50-70 cc is created from the cardia region, which is the initial part of the stomach. This pocket is separated from the main stomach with the help of a stapler. Then, the small intestines are joined (anostomosis) to this pocket 60-100 cm ahead. In the last stage, the end of the small intestine, which brings secretions from the remaining stomach and duodenum, is joined to the main intestinal system. The remaining stomach is not removed except for the pouch (pocket). The operation takes about 1.5 hours.
Who Can Have RNY Gastric Bypass Surgery?
RNY gastric bypass surgery is a surgical method generally applied in patients who may be harmed by gastric sleeve surgery such as severe reflux, in patients who are not suitable for gastric sleeve surgery or in the reconstruction of gastric sleeve surgery. It remains one step ahead of sleeve gastrectomy surgery in patients where diabetes control is more important.
Risks of RNY Gastric Bypass
The risks of RNY gastric bypass may be higher than other surgical procedures. The risks generally cover the first two weeks after the operation and the operation process. There is no risk that may occur 15 days after the surgery. The risks can be listed as follows;
Bleeding risks: This risk is present in all surgical interventions. Symptoms include intense dizziness and a drop in blood pressure.
Embolism risks: this risk is minimized by giving blood thinners 24 hours before the operation and wearing compression stockings.
Leakage risks: symptoms can manifest themselves as a severe increase in pulse rate, trembling, severe abdominal pain and intense weakness.
Dumping syndrome risk: a side effect. It is the rapid passage of nutrients from the stomach to the small intestine. Symptoms include severe abdominal pain and diarrhea in the first half hour after feeding.
What Should Be Considered After RNY Gastric Bypass Surgery?
After RNY gastric surgery, hospitalization is required for 3-4 days. One week is enough time to return to normal life. Postoperative patients should be followed up regularly for the first year. It is important that vitamin and mineral intake is sufficient in the first year. The patient should come to regular monthly doctor and dietitian appointments.
Nutrition After RNY Gastric Bypass
Nutrition after RNY gastric surgery is as follows;
Patients are fed liquid for the first 8 days.
The 8-day nutritional content is as follows; sugar-free fruit juices, protein-rich liquid drinks, lactose-free milk, sugar-free vegetable milk, grain-free soup enriched with meat and chicken broths.
The next phase starts on day 9 and lasts until day 22.
This is the puree period. The patient's diet is expanded to include eggs, cheese, low-sugar fruit, vegetable purees with yogurt or minced meat, and protein-enriched dairy products.
Another phase starts on Day 23. The patient switches to a standard and healthy diet and follows the diet specially prepared for him/her by the dietitian.
What Not to Eat After RNY Gastric Bypass
Things that should not be eaten after RNY gastric bypass are as follows; acidic drinks, fast-food, sugary foods, alcohol. The patient should adopt a healthy diet both immediately after surgery and in general. This makes it easier to lose weight. Continuing to eat healthy also ensures that the weight lost is not regained.
