Weight loss surgery: methods, indications, and risks

Weight loss surgery and precautions

What are some common ways to play in the city market, and what are their characteristics?

Minimally invasive treatments for severe and morbid obesity include: gastric bypass surgery (restricting intake and reducing smoking).

(Restricted intake), adjustable gastric banding (restricted intake), sleeve gastrectomy (restricted intake). Currently this

These surgeries can all be performed laparoscopically, thus becoming minimally invasive weight loss surgeries.

(1) Gastric bypass surgery: The upper part of the stomach is connected to the proximal jejunum, bypassing most of the stomach and duodenum.

Diuretics can typically help with weight loss of 50 kg, which is 60% to 70% of excess weight, and is also beneficial for type 2 diabetes.

The effective relief rate was 83%, with an efficacy rate as high as 95%.

(2) Adjustable gastric band: An adjustable gastric band made of silicone is tied to the entrance of the stomach.

"Pentacle" to restrict food intake; within 2, 4, and 5 years post-surgery, overweight weight decreased by 49%, respectively.

55%, 57%. The effective remission rate for type 2 diabetes is 77%.

(3) Sleeve gastrectomy: A portion of the stomach is removed, leaving a volume of approximately 100 ml.

It can reduce overweight by 60% to 70% within 2 years. The effective remission rate for type 2 diabetes is 77%.

Indications for weight loss products for obese patients in China

Severe obesity is often accompanied by complications, shortened lifespan, and poor response to conservative treatment; weight loss

Surgery can achieve long-term weight loss, treat complications, and extend lifespan; it is the only way to achieve long-term weight loss for morbid obesity.

Treatment methods. In recent years, weight loss techniques have grown rapidly worldwide, especially in Europe and America, with global weight loss rates increasing annually.

More than 200,000 obesity surgeries have been performed, with over 50% of them occurring in the United States. One-third of the American population is overweight.

One-quarter of them are obese; bariatric surgery has become the most frequently performed gastrointestinal surgery in the United States.

Its best effect

Report: 78% of diabetes cases achieved complete remission, and 87% achieved partial remission; over 70% of hyperlipidemia cases showed improvement.

Solution; 61.7% of hypertension cases were relieved; 78.5% experienced partial relief; over 80% of sleep apnea cases were alleviated.

Solution or improvement.

For Chinese people, mild, moderate, and severe obesity carries a high, or even extremely high, risk of complications.

Risk. Therefore, the BMI level for surgical indications in Chinese people is lower than that in European and American countries. Obese patients in European and American countries

Indications for bariatric surgery: ① Morbid obesity (BMI > 40); ② Moderate obesity (BMI = 30-40)

And related diseases, such as: severe diabetes, obesity-hypoventilation syndrome, obesity-related cardiomyopathy, etc.

Severe sleep apnea and osteoarthritis affect quality of life.

In October 2007, the Endocrinology Surgery Group of the Surgical Branch of the Chinese Medical Association, based on the physical condition of the Chinese population...

Characteristics and pathogenesis features; surgical indications for obese patients in my country have been published: ① Confirmation of the presence of symptoms related to obesity.

Related metabolic disorders and predictive weight loss can be effectively treated. Such as type 2 diabetes, cardiovascular disease,

Fatty liver, lipid metabolism disorders, sleep apnea syndrome, etc. ② Waist circumference: Men ≥ 90cm,

Women ≥80cm. Dyslipidemia: TG (triglycerides) ≥1.70mmol/L; and/or fasting.

Blood HDL-ch (high-density lipoprotein cholesterol): Men <0.9 mmol/L, women <1.0 mmol/L.

③ Stable or steadily increasing weight for more than 5 consecutive years, with a BMI ≥ 32 kg/m². ④ Age 16-65. ⑤ Mentally ill.

If non-surgical treatment is ineffective after more than one course or conservative treatment is not tolerated. ⑥ No ethanol or drugs.

Dependence and severe mental and intellectual impairment. ⑦ The patient understands the procedure of bariatric surgery and accepts it.

Be aware of the potential risks of surgical complications; understand the impact of postoperative lifestyle and dietary changes on postoperative recovery.

The importance of this, and the ability to cope with it, and to actively cooperate with postoperative follow-up. Those who meet one of the above ①~③,

For those who meet all of the conditions in ④ to ⑦, surgical treatment may be considered.

What preparations should be made before surgery for obesity?

Before undergoing weight loss surgery, patients and their families should first be fully prepared mentally, and after the surgery...

Dietary control and lifestyle changes may be lifelong for patients; therefore, it is essential to first fully consult with family members.

With the support of family and friends, and after fully consulting with the doctor to understand the benefits and risks of the surgery.

The patient and their family should carefully understand the relevant surgical information, surgical method, surgical risks, and what to do if adverse events occur.

The countermeasures and consequences, expected surgical results (such as the pattern of postoperative weight loss), and the outcome of accompanying diseases, etc.

Patients should undergo routine physical examinations and blood biochemistry tests before surgery, and should also be prepared according to the patient's condition.

The presence and severity of any obesity-related comorbidities will be assessed for appropriate special treatment. Preoperative diagnosis and treatment will be conducted by the surgical and anesthesia teams.

Departments of Medicine, ICU, Endocrinology, Nutrition, Cardiology, Respiratory Medicine, Psychology, Gastroenterology, Gynecology

A collaborative team composed of obstetricians and specialized nursing staff organized multidisciplinary consultations. The surgical plan was scheduled by the surgeon.

The procedure and surgery date were determined, and the patient's condition was comprehensively monitored. Relevant disciplines assessed the situation based on the examination results.

The patient's tolerance for surgery should be assessed, and all necessary preparations should be made. For example, the endocrinologist should adjust blood sugar levels before surgery to ensure adequate blood sugar control.

Stable to normal levels; nutritionists develop preoperative dietary plans for patients; cardiology department regulates...

Blood pressure and heart rate should be monitored, and medications that may affect intraoperative circulation should be avoided as much as possible; the respiratory department should monitor the patient's sleep apnea.

For patients with sleep apnea syndrome and hypoxemia, non-invasive mechanical ventilation is used for respiratory therapy; for obese patients...

The patient required general anesthesia with difficult intubation; therefore, the anesthesiology department should develop a targeted anesthesia plan and make corresponding preparations before the operation.

What factors influence the effectiveness of weight loss products?

Factors influencing the outcome of bariatric surgery mainly include: the patient's age, pre-operative weight, and the patient's...

The overall physical health condition, surgical method, and whether the patient can adhere to the dietary guidelines before and after surgery.

Postoperative follow-up adherence, postoperative exercise capacity, patient's determination, and cooperation from family and friends are all factors to consider.

Among these factors, patient compliance and adherence to follow-up are the decisive factors affecting the outcome of bariatric surgery.

What are the risks of surgical hand surgery?

With continuous improvements in surgical techniques and approaches, the postoperative complications of bariatric surgery have significantly decreased.

Low. The complexity of the surgery, the time after surgery, and the surgical approach all determine the various complications.

The incidence of complications varies. Biliary-pancreatic diversion/biliary-pancreatic diversion-duodenal transposition is relatively complex, involving the stomach...

Intestinal tract involvement is involved, with an early postoperative mortality rate as high as 11%; gastric bypass surgery is the next most common, with a mortality rate of 30 days and...

The 90-day mortality rates were 0.29% and 0.35%, respectively; adjustable gastric banding is relatively simple to perform, and its morbidity...

The mortality rate is 0.1%.

Early postoperative complications are similar to those of routine gastrointestinal surgery, mostly anastomotic leakage,

The occurrence of bleeding, intestinal obstruction and infection, and late postoperative complications varies depending on the surgical method.

The difference lies in the fact that malnutrition (vitamin and mineral deficiencies) is more likely to occur, and it is more common in bile-pancreatic bypass surgery.

Biliary/pancreatic bypass surgery – duodenal transposition and gastric bypass. Postoperative complications may include biliary and urinary tract infections.

It could be due to kidney stones, deep vein thrombosis in the lower extremities, or pulmonary embolism.

What long-term problems might arise from manual therapy for weight loss?

After bariatric surgery, rapid weight loss can easily lead to gallstone formation, resulting in postoperative cholelithiasis.

The incidence rate is 3% to 30%. Malnutrition may also occur, most commonly iron-deficiency anemia, folic acid deficiency, and vitamin deficiency.

B₁₂ deficiency (high incidence, up to 70%), calcium and vitamin D deficiency. With the relative increase in calcium...

Lack of this condition increases the risk of osteoporosis. Patients who undergo gastric bypass surgery may develop dumping syndrome postoperatively.

Symptoms of hypoglycemia after eating, and 70% of patients experience varying degrees of gastroparesis.

The main symptoms are abdominal distension and abdominal pain after meals.
