What Is Stomach Stapling?

Gastric bypass surgery refers to a series of similar surgical procedures used to treat obesity. The common feature is that the surgery firstly divides the stomach part into two parts, the smaller upper part and the larger lower part. Arrange the position of the small intestine, change the way food passes through the digestive tract, slow down the rate of gastric emptying, shorten the small intestine, and reduce absorption. Surgeons have developed several different arrangements, forming several branches of gastric bypass surgery.

Higher risk of surgery

Morbidly obese patients who want to lose weight and get healthy will have one more surgical option in the future.

Compared with traditional gastric cuff surgery or partial gastric resection, gastric bypass surgery involving reorganization of the small intestine is more risky, but it is generally believed that it is more effective than the other two surgical methods to achieve long-term weight loss, so gastric bypass surgery is becoming more and more popular. More popular.

In the United States alone, nearly 250,000 people undergo this operation each year.

The operation is performed laparoscopically, which means that the doctor only needs to make five small incisions in the patient's abdomen to perform the operation. The operation is performed in three steps. First, the doctor staples or sutures a part of the stomach, leaving a small gastric sac with a capacity of about 30 ml, then cuts the jejunum, and finally connects the jejunum to the small sac.

Surgery is mainly to reduce the capacity of the stomach and shorten the process of nutrient absorption in the small intestine. The two-pronged approach helps sick obese patients achieve weight loss.

80% of morbidly obese patients undergoing gastric bypass surgery can return to standard weight within two years, compared with only 60% and 70% of patients who can return to standard weight after surgery for gastric hoop surgery or partial gastric resection.

The risk of gastric bypass surgery is higher.

Other known complications include leakage of food from the small intestine interface, which causes inflammation of the interface, and venous thrombosis may also occur after surgery.

Doctors only recommend bariatric surgery for morbidly obese patients with a body mass index (BMI) of more than 32.5 after the patient's dietary adjustments or weight management methods such as medication have become ineffective.

The recovery time of gastric bypass surgery is not much different from traditional gastric cuff surgery. Patients can only eat fluid food for the first three to four weeks, but most patients can return to work one month after the operation.

The charges for the three types of bariatric surgery are also similar. For subsidized B2 patients, the cost of the operation is about 5,000 to 6,000 yuan.

Laparoscopic Gastric Bypass

Due to the need to reconstruct the small intestine through surgery, the risk of surgery is relatively high. Some patients may have complications of leakage of food from the small intestine interface after surgery, which may cause inflammation of the abdominal mucosa.

Compared with other surgical methods, 80% of patients undergoing this operation can be reduced to standard weight within two years. Up to 80% to 90% of obese patients are cured of diabetes after surgery, and no longer need to take medicine to control diabetes.

Gastric band surgery (Lap Band)

Relatively speaking, the risk of this operation is low. The doctor puts an adjustable wide tight rubber ring on the stomach and divides the stomach cavity into upper and lower parts. If necessary, the doctor will inject a saline sac to tighten the stomach cuff to reduce the stomach capacity. The patient will feel full after eating a small amount of food.

If the patient who lacks self-discipline continues to overeating, the cuff may loosen, or the small gastric sac may be enlarged and lose the effect of reducing gastric capacity.

Removal of part of the stomach (Lap Sleeve)

Removal of 85% of the stomach permanently reduces the capacity of the stomach, which makes patients more likely to feel full, thereby reducing the amount of food they eat.
