Laparoscopic Sleeve Gastrectomy (2)

Benefits of laparoscopic sleeve gastrectomy

• Obvious weight loss: ~70-80% of the stomach will be removed thus significantly reduce stomach volume and induce a much earlier sense of satiety.
• 
  
• Effective diabetic control: with the reduced stomach volume and changes in hormones, such as increasing glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) for diabetes treatment that is stimulated by faster stomach emptying.
• 
  
• Reduced appetite: There is an immediate reduction in levels of the appetite stimulating hormone – Ghrelin, thus significantly reduce patient’s hunger sensation and appetite.

Risks of laparoscopic sleeve gastrectomy

• Low risk: overall mortality risk is <1%.
• Irreversibility: once the greater curve of the stomach is removed, normal stomach anatomy cannot be reinstated.
• Heartburn: patients may experience a higher incidence of reflux / heartburn following surgery.

Laparoscopic Sleeve Gastrectomy (1)

Want to have a better control of eating volume without the need to avoid various foods? Laparoscopic sleeve gastrectomy, a restrictive minimally invasive laparoscopic surgery, is the most widely performed weight loss surgery in Asia. By reducing the stomach size, patients will feel a sense of fullness much earlier, and thereby substantially reducing the volume intake.

Besides more effective weight loss, this surgery is effective in diabetic treatment with a remission rate of almost 70%. This surgery can significantly suppress the secretion of Ghrelin – a powerful appetite stimulating hormone. Patients recover quickly from surgery and are able to return to their daily activities in a short period of time. In order to achieve your target body weight, patients will have regular follow up with Dr. Wong and his team of allied health specialist (including dietitian and physiotherapist).

Procedure of laparoscopic sleeve gastrectomy
This surgery is indicated for patients with BMI over 30. Two weeks prior to surgery you are instructed to have only fluid diet and milk supplements. The surgery is performed under general anesthesia. Dr. Wong will make 4-5 small (1-1.5cm) incisions and remove 70-80% of the stomach in order to create a ‘banana’ shaped stomach. The entire procedure last for about one and half hours and patients will be discharged from hospital 3-4 days after surgery.

After your surgery, fluid and congee diet must be maintained within the first month in order to allow for good wound healing. After then, a “new” normal diet can be resumed. All patients must follow dietitians’ advise to ensure effective weight loss.

Is Bariatric (weight loss) surgery a saft and effective option for severely #obese children or adolescents?

Weight loss surgery among adolescents (aged 11-17) is becoming increasingly common in Europe and the US, but is still rare among Asian patients. According to estimates from U.S. News and World Report, about 1,500 to 2,000 teenagers receive bariatric surgery in the US each year, out of an estimated 180,000 overall cases including adults. In Asia, statistics show a monumental rise in child obesity: 46 million children were characterised as obese and 300 million described as overweight in China alone, according to a 2014 study. Meanwhile, in Malaysia, often described as Southeast Asia’s ‘fattest’ country, over a quarter of children were reported to be overweight or obese. In light of this trend, Global Health and Travel asked bariatric surgeons across the region if they see weight loss surgery as a viable, safe option for dangerously obese teenagers who cannot lose weight by conventional means.

At the moment in Hong Kong, the guidelines for bariatric surgery currently exclude patients who are under 18. We have had, in the past, a few cases that we did surgery for adolescents, but they were under experimental trial settings in university hospitals.

Recently there’s been quite a bit more attention in particular from the US, in performing bariatric surgery for obese children or adolescents, with some pretty good results. However, the current consensus is that it’s not really for the average bariatric surgeon to apply this in Asia yet.
Currently there are just a few operations that have been studied for adolescents, like laparoscopic sleeve gastrectomy, laparoscopic gastric band, and gastric bypass. There are, of course a whole range of other surgeries that are available, but they might not be suitable for adolescents.
