What are the minor gastric surgeries

There are big and small surgeries, and the same is true for gastric surgery. Minor gastric surgeries are more common and are primarily for the purpose of weight loss, such as gastric banding and gastric reduction. Through such surgery, the hunger of dieters can be greatly reduced, thus achieving the goal of weight loss. Gastric polypectomy is also a minor gastric surgery that can be performed through gastroscopy, avoiding the damage to the patient's body caused by surgery.

1. Gastric Band Surgery

1. Concept

Gastric banding is usually done laparoscopically. This surgery involves placing a low-pressure, flexible silicone band around the upper part of the stomach, like a belt, dividing the stomach into two parts with a small opening between the two parts to allow food to pass through. When eating, food quickly fills the smaller upper part of the stomach. When this part of the stomach is filled and expanded, it stimulates the nerves in the stomach to send signals to the satiety center of the brain. The brain's regulatory center will make people feel full for several hours.

2. Advantages

Limiting the amount of food you eat at each meal

Food passes through the digestive tract unchanged so it can be fully absorbed

Can be done with minimally invasive surgery (laparoscopic surgery)

Can increase or decrease food restriction by adjusting

The surgery is reversible (can return to the pre-surgery state)

Gastric reduction surgery

1. Concept

This surgery involves partially removing the distal end of the stomach and then anastomosing it to the intestine. The principle is to remove part of the stomach so that obese people can eat less and lose weight. The principle of gastric reduction surgery is to use laparoscope to vertically cut out the greater curvature of the stomach, so that the stomach forms a small stomach pouch of about 150cc, which can hold about 4-5 ounces of food.

2. Advantages

1. The weight loss effect is similar to gastric bypass surgery and better than gastric banding

2. No foreign objects implanted, no risk of rupture, leakage or abrasion

3. No adjustment required

4. The quality of food intake is higher than that of gastric banding

5. Safer than gastric bypass surgery

6. Does not affect the absorption of vitamins and minerals

7. Fewer long-term side effects

8. Faster recovery from surgery

9. If weight loss is not satisfactory, gastric bypass surgery can be performed

10. Gastric reduction can also be performed using minimally invasive laparoscopic methods

3. Gastric Polypectomy

1. Concept

Gastric polyps refer to papillary protrusions that grow on the surface of the gastric mucosa, which are generally caused by abnormal proliferation of the gastric mucosa. Endoscopic gastric polypectomy includes high-frequency electrocoagulation resection, nylon ligation, argon plasma coagulation and microwave ablation. Among them, high-frequency electrocoagulation resection is the most widely used treatment method.

2. Indications

1) Sessile or sessile polyps smaller than 2 cm.

2) Polyps that progressively enlarge.

3) Patients whose pathological examinations show adenomatous polyps with dysplasia, suspected cancer and cancer.

3. Contraindications

1) People with severe hypertension, diabetes and coagulation dysfunction.

2) Those who are intolerant to anesthesia or gastroscopy.

4. Postoperative Care

1) Pay attention to the presence of bleeding, abdominal pain and black stools.

2) Avoid strenuous exercise within one week after surgery.

3) Do not eat for 4 hours after surgery and eat semi-liquid and soft food for three days.
