Obesity Surgery

Sleeve Gastrectomy (Sleeve Gastrectomy)

The main reason for the acceptance of surgical treatment of obesity is that it can be performed quickly, it causes less injury to the patient, patients lose weight well and obesity-related side effects improve faster. However, it should be seen as an important advantage that more advanced second stage obesity surgery can be easily performed if necessary.

After this surgery, it has been determined that patients lose 50 percent to 80 percent of their excess weight in about 12 months, while other obesity-related diseases improve.

How is Gastric Sleeve Gastrectomy Surgery Performed?

The large edge of the stomach is cut away to create a stomach tube with a volume of 60 to 120 ml.

What happens as a result of sleeve gastrectomy?

Sleeve gastrectomy surgery is an important obesity surgery that shows its effect in a short time, 35-70 percent of the total excess weight is lost in six months, and 33-81 percent of the excess weight is lost in the 12th month. The weight lost in three years is close to the weight lost after Gastric By-Pass surgery.

    Nutrition After Gastric Sleeve Gastrectomy

    Sleeve gastrectomy is the removal of 3/2 of the stomach to reduce the volume of the stomach, the remaining stomach volume is approximately 90-100 ml and the reconstructed stomach is more or less tubular.

    The essence of this surgery is to reduce the volume of the stomach and thus provide a feeling of satiety with small portions.

    The special nutrition plan to be applied for about 6 weeks after surgery covers the period until the patient’s digestive activation, tolerance, and the functions of the stomach and intestinal system return to normal. In this process, dietitian control will help to complete the process more effortlessly. In sleeve gastrectomy surgeries, the nutrition plan is completed with puree, soft, solid and normal nutrition respectively.

    Weight Gain After Gastric Sleeve Gastrectomy?

    After sleeve gastrectomy, weight regain is possible if the stomach tube expands over time.

    Causes of Weight Gain;

    • Use of an overly wide spark plug.
    • Insufficient removal of the back wall of the stomach
    • Excessive pressure on the stomach tube due to large bites.
    • Recurrent vomiting.
    • Obstruction in the gastric outlet or intestine

    If Weight Gain After Gastric Sleeve Gastrectomy

    • The laparoscopic method can once again remove the excess of the enlarged stomach.
    • Gastric by-pass surgery can be performed.
    • Laparoscopic duodenal switch surgery can be performed.

    Weight Loss after Gastric Sleeve Gastrectomy?

    Weight loss in sleeve gastrectomy surgery occurs through 2 mechanisms:

    1. Weight loss due to a mechanical restriction by reducing the volume of the stomach and reducing gastric movements,
    2. Since the stomach tissue that produces a substance known as ghrelin is removed, weight loss occurs as a result of a hormonal change. Since the fundus region of the stomach where ghrelin is produced is removed in sleeve gastrectomy, appetite decreases and weight loss occurs.

    Gastric Bypass Surgery

    Gastric bypass surgery is a type of metabolic and bariatric surgical procedure used to treat obesity. This surgery aims to limit food intake and reduce the absorption of nutrients by removing part of the stomach and connecting or redirecting it to a specific area of the intestine. This is considered an effective method to promote weight loss and manage obesity-related health problems.

    What are the Types of Gastric Bypass Surgery?

    There are 4 different types of Gastric Bypass Surgery: Mini Gastric Bypass, Biliopancreatic Bypass, Roux-en-Y Gastric Bypass, Bypass with Sleeve Gastrectomy.

    Mini-Gastric Bypass (MGB):

    There are 2 weight loss mechanisms with this surgery.

    1. With the tube stomach created, excess food intake is prevented and the rate of eating is reduced.
    2. With the connection between the new tube stomach and the small intestine, food passes directly into the small intestine without passing through the large stomach and dedonum, preventing absorption of the food taken.

    Mini-Gastric Bypass (MGB) surgery is often compared with Roux en Y Gastric Bypass (RYGB) surgery, which has the same mechanism of action. The most important advantage of MGB is that it is technically easier to perform and the operation time is shorter.

    Roux en Y Gastric Bypass (RYGB)

    RYBG surgery works in 2 ways.

    1. By reducing stomach volume, food intake is reduced.
    2. Foods, especially high-calorie sugary foods, are prevented from being absorbed because most of the stomach, the 12-finger intestine (dedonum) and the beginning part of the jejunum (small intestine) are bypassed (disabled).

    Following food intake, nutrients pass through the esophagus into the small stomach and then directly into the small intestine (they do not pass through the large stomach, duodenum and the first part of the jejunum). Thus, all the food passes directly into the small intestine without being absorbed because it does not pass through these parts of the digestive tract that are responsible for absorption.

    On the other hand, secretions from the deactivated sites (gastric juice, liver bile, pancreatic juice and duodenal enzymes) are mixed with food at the junction with the small intestine and pass into the common pathway.

    Biliopancreatic Bypass

    In this type, the stomach is made into a small pouch and is directly connected to the middle section of the small intestine. Food goes into this new stomach pouch and is directed to the last part of the digestive tract, bypassing the upper part of the intestines. The absorption of nutrients is severely limited.

    Bypass with Sleeve Gastrectomy

    In this method, most of the stomach is removed, leaving the stomach in the form of a tube, which is directly connected to the small intestine. By shrinking the stomach and connecting it directly to the intestine, food intake is limited and absorption of nutrients is reduced.

    Gastric bypass surgery is used to treat obesity and reduce obesity-related health problems. However, each type of surgery has advantages, disadvantages and risks. Therefore, a detailed evaluation and consultation with a bariatric surgeon should be done to decide which type of surgery is appropriate.

    Who Can Have Gastric Bypass Surgery?

    Gastric bypass surgery is an option considered for the treatment of obesity and is performed on individuals who meet certain criteria. As each patient situation may be different, a comprehensive evaluation and recommendation from a bariatric surgeon is essential to evaluate and determine this type of surgery. 

    Suitable candidates for gastric bypass surgery are usually overweight or obese individuals. Those with a VKI of 40 or higher may be candidates for this surgery. Those with a BMI between 35-39.9 may consider this surgery if they have obesity-related health problems (e.g. type 2 diabetes, high blood pressure) or if obesity cannot be controlled with diet and exercise.

    Gastric bypass surgery can be considered especially for those with obesity-related type 2 diabetes, high blood pressure, sleep apnea, heart disease, joint problems and other obesity-related conditions. People between the ages of 18-65 are suitable candidates for gastric bypass surgery.

    These criteria and other health conditions are assessed on an individual basis and eligibility for surgery is determined. Each case is different, so the consultation and guidance of a bariatric surgeon is important for the decision on surgery.

    Nutrition after Bypass Surgery

    These surgeries are performed by reducing the volume of the stomach and reducing the areas of nutrient absorption from the intestines, and their effect on weight loss is both absorption and limited food intake.

    Bypass ameliyatlarında mide ve bağırsak fonksiyonlarının tam anlamı ile yerine gelene kadar sıvı, püre, yumuşak katı ve sağlıklı beslenme programlarına adım adım uyulması vücudun kendisini onarması ve sorunsuzca iyileşmenizi sağlayacaktır.
