Bariatric Surgery - Antalya Obesity
Sleeve gastrectomy operation is the most preferred type of operation among bariatric surgeries that provides sufficient weight loss alone. In the gastric sleeve procedure, first of all, the fat tissues adhering to the stomach are separated with the latest technological devices that perform vascular sealing and cutting together. After this stage, a gastric stomach is swallowed by the patient and placed in the stomach. Accompanied by the calibration of the gastric sleeve, 80 percent of the left side of the stomach is separated from the gastric sleeve with 3 rows of stapling instruments and the excess stomach tissue is taken out of the abdomen through the opening what we call the trocar hole. The operation is finished after leakage tests are applied to the staple lines. The sleeve gastrectomy operation is performed with closed laparoscopy method by passing through 5 holes about one centimetre in size. Thanks to laparoscopic surgery, patients experience less pain and can return to their social life earlier.
a- How to Lose Weight with Sleeve Gastrectomy?
Due to the reduced stomach volume after the operation, small amounts of food fill the stomach and at the same time, patients do not feel hunger due to the absence of hunger-inducing hormones released from the gastric fundus due to the surgical removal of the gastric fundus.
b- What are the advantages of this surgery?
Sleeve gastrectomy is a type of surgical procedure that minimally interferes with the anatomy of the digestive system. The operation time and technical requirements are less than other types of surgery, and vitamin and mineral losses are less common than other types of surgery.
c- What are the disadvantages of this surgery?
There are no known short-term disadvantages of sleeve gastrectomy, which is a problem-free surgical procedure. The results in a term of 20-30 years are not yet known.
d- Post-operation period
Although surgeons have different opinions about the time to start liquid food intake after the operation, patients start to consume liquid clear foods, if no gastric leakage is observed after an abdominal X-ray taken within the first three days after the operation. After this phase, which is under the control of a dietitian, patients gradually switch to solid foods some time later.
e- What Are the Risks of This Surgery?
Risks related to surgical technique;
– Staple-line leak
– Intra-abdominal bleeding from the spleen or fatty tissue area
– Leaks and gastric edge abscesses due to opening of the staple-line
– Embolism (blood clot) to the lungs
– Wound infections
f- How Can These Risks Be Prevented?
Gastric Bypass (Roux-en-Y)
Although gastric bypass surgery causes some absorption restriction, it is basically an operation carried out to reduce the gastric volume. However, the connection of this small volume obtained with the remaining digestive tract is provided by anastomosis (refurnishing with a mouth) of this area with the small intestines.
a- How to perform the gastric bypass surgery?
In this surgery, firstly, a gastric pouch corresponding to approximately 5 percent of the entire gastric volume is created from the end of the oesophagus, and 70 centimetres of the small intestines coming after the stomach are cut and bypassed with this blind small-volume pouch. The other end of the intestines cut from the 70th centimetre opens to the hundredth centimetre after the gastro-intestinal connection.
b- What are the Advantages of Gastric Bypass?
With this surgery, the amount of calories taken is significantly reduced. The volume ratio of the food intake decreases.
This surgical procedure provides healing for many diseases such as
– Type 2 Diabetes
– Joint disorders
– Sleep problems
– High cholesterol due to excess weight
c- What are the Disadvantages of Gastric Bypass?
The following complications can be seen in the post-operative process.
– Intestinal obstruction and adhesions
– Accumulation of gastric fluid in residual stomach tissue and bloating in connection therewith
– Stenosis at the gastrointestinal junction
– Problems caused by vitamin and mineral deficiency
– Gallstone formation
– Failure to visualize the inner surface of the closed gastric pouch
– Disruptions in the functioning of the digestive tract due to damage to the vagus nerve, which regulates the neural activity of the digestive tract
In addition, feared risks such as leakage and embolism (clotting), which are observed in all obesity surgeries, are also present in these surgeries.
