MINI GASTRIC BYPASS
WHAT IS MINI GASTRIC BYPASS?
Mini gastric bypass is an effective surgery that combines some features of standard gastric bypass and sleeve gastrectomy. The upper part of the stomach is formed into a tube and connected to the small intestines.
Mini gastric bypass can be performed as a stand-alone weight loss procedure. It can also be applied to patients who have undergone gastric banding or sleeve gastrectomy surgery but have not lost weight, or to patients who have had complications due to gastric banding and have decided to undergo revision surgery.
In this operation, the upper part of the stomach is separated from the rest of the stomach in the form of a thin tube. It becomes a new and smaller stomach. This new stomach is then attached after the first 150-200 cm of small intestine. The remainder of the stomach and upper part of the small intestine remains in the body but does not take part in digestion.
WHAT ARE THE TECHNIQUES USED IN MINI GASTRIC BYPASS SURGERY?
In this technique, the stomach is separated from the rest of the stomach by forming a tube with a thickness of about 2 cm and a volume of 50-60 cc (= 4 tablespoons of water), similar to the continuation of the oesophagus and similar to the tube stomach. The new small and narrow gastric tube is joined by suturing a region in the middle of the small intestine (200 cm from Treitz) without cutting it. The biggest difference of this technique from RYGB is that the integrity of the intestine is not disrupted, and the procedure is performed in a single region.
IN WHICH SITUATIONS SHOULD I HAVE MINI GASTRIC BYPASS SURGERY?
It can be applied to patients who have undergone gastric banding or sleeve gastrectomy surgery but have not lost weight, or to patients who have had complications due to gastric banding and have decided to undergo revision surgery.
POST-PROCEDURE RECOVERY PROCESS
Up to 2 years after surgery, 70-85% of excess weight is lost.
Many diseases associated with being overweight, such as sleep apnea, type 2 diabetes, joint diseases, high blood pressure, and polycystic ovary syndrome, get better or completely disappear with surgery.
WHAT ARE THE RISKS OF GASTRIC BYPASS SURGERY?
- In this procedure, bleeding, infection, postoperative ileus (intestinal obstruction), hernia and general anesthesia complications can be seen, which can also be seen in many other abdominal surgeries.
- The most serious risk is leakage that may occur in the connection between the stomach and small intestine and a second surgery may be needed as a result.
- A number of additional surgical risks increase due to obesity. Blood clot formation (embolism) and cardiac problems may occur in the feet and lungs.
- 10-15% of patients who undergo this surgery experience some of the above complications. In general, more serious complications are rare and the common ones are acceptable and treatable.
WHICH PATIENTS IS GASTRIC BY-PASS SURGERY SUITABLE FOR?
Obesity surgeries are evaluated according to body mass index. 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, and sleep apnea are suitable for this surgery.
HOW LONG WILL YOU STAY IN THE HOSPITAL AFTER GASTRIC BY-PASS SURGERY?
You usually stay in the hospital for 3-4 days. Problems that may occur during the preoperative evaluation and postoperative recovery period may extend.
IS IT POSSIBLE TO LIFT HEAVY AFTER GASTRIC BY-PASS SURGERY?
After leaving the hospital, heavy activities should be restricted. One should not lift heavy loads for 6 weeks.
WHEN THE CARS CAN BE USED AFTER GASTRIC BY-PASS SURGERY?
You should not drive for 2 weeks after surgery. You can walk, climb stairs and take a shower.
WHEN TO RETURN TO WORK AFTER GASTRIC BY-PASS SURGERY?
Patients with a quiet business life can return to work after 2-3 weeks. Patients whose work include intense physical activities should wait 6-8 weeks after surgery.
