Gastric Band

gastric-band

A great option for obesity is the laparoscopic Adjustable Gastric Band (LAGB).

This is a keyhole procedure requiring a short hospital stay and the insertion of a silicon ring around the upper stomach. This holds up the passage of food and creates a small pouch above it restricting portion size. There is also a profound effect in reducing hunger which is not yet fully understood. Several weeks after insertion, the band is filled with saline by an inspection through the skin on the abdomen into a chamber which connects via a tube with the band. This places extra pressure on the stomach and starts the process of dietary restrictions and weight loss. Gastric bands usually require several adjustments in the first six months after surgery. Regular patient follow up is important to achieve better results.

Gastric Band Advantages

  • Relatively simple and potentially reversible procedure.
  • Patients may lose 50-60% of their excess weight.
  • Good documented evidence of remission or improvement of medical conditions such as: Diabetes, hypertension and sleep apnoea.

Gastric Band Risks

  • Certain foods such as breads and fibrous meats can be difficult to digest and may cause obstructive symptoms (eg: discomfort, regurgitation).
  • There is a risk of the band slipping or the small gastric pouch dilating with time.
  • There is a small risk of gastric band erosion.

Gastric Sleeve

The sleeve gastrectomy is performed via key hole surgery. 75-80% 0f the stomach (it is only a restrictive procedure) is removed. It does not involve any surgery on the intestine (may cause malabsorption). Sleeve gastrectomy has also been called the tube gastrectomy and/or vertical sleeve gastrectomy. It  basically consists of converting a stomach that looked like a pouch into a long tube; therefore the name “sleeve.”

The sleeve gastrectomy (SG) removes three-quarters of the stomach, which provides for quicker satiety (sense of fullness) and decreased appetite. The smaller stomach restricts food intake by allowing only a small amount of food to be eaten at any one time. The valve at the outlet of the stomach remains intact which provides normal process of stomach emptying to continue. This allows early feeling of satiety.

SG has been utilized in the treatment of obesity since 2003. There are no new connections made between the stomach and small intestine in this procedure. There is no rerouting of the intestine. There is no malabsorption.  Dumping syndrome is infrequent.. The Sleeve Gastrectomy is believed to have an advantage over the Adjustable Gastric Band due to removal of the part of the stomach that produces the hormone (Ghrelin) that controls the desire to eat.

The potential complications of the operation on an average are typically less than 1.5%.

Weight loss (bariatric) surgery requires long-term monitoring and changes to diet and lifestyle.

Studies show that patients who commit to eating healthy food, take nutritional supplements and have routine blood work for monitoring purposes have the best long-term results.

Surgery gives patients a tool to assist with weight loss. Patients must be committed to making the emotional and physical changes (lifestyle changes) necessary after weight loss surgery. This commitment will ensure successful weight loss and long-term weight maintenance.

Lack of exercise, poorly balanced meals, constant grazing, eating processed carbohydrates and drinking sweet beverages are some of the most common reasons for weight regain.

Sleeve Gastrectomy Advantages

The sleeve gastrectomy has the following advantages:

  • gastric-sleeve-num-01
    It does not require the implantation of a foreign body such as a silastic ring, port and connecting tube used in gastric banding.
  • gastric-sleeve-num-01
    The procedure mechanically decreases the size of the stomach which decreases the secretion of the hormone (Ghrelin) that is responsible for appetite.
  • gastric-sleeve-num-01
    Patients should lose around 60-80% of their excess weight over 12 months.
  • gastric-sleeve-num-01
    Patients generally have a better eating quality of life
    (eg. able to eat bread and meat easily).
  • gastric-sleeve-num-01
    Good documented evidence of remission or improvement of medical conditions such as: diabetes, hypertension and sleep apnea.

Sleeve Gastrectomy Risks

The sleeve gastrectomy has the following risks:

  • gastric-sleeve-num-01
    Staple line leak: an internal infection from leakage of digestive juices from the gastric staple line-is uncommon. This may require surgery to repair.
  • gastric-sleeve-num-01
    Significant bleeding from the gastric staple line is a rare occurrence.
  • gastric-sleeve-num-03
    May worsen the symptoms of acid reflux

Gastric Bypass

Gastric Bypass is one of the most common surgical procedures used in the treatment of Obesity around the world.

Gastric Bypass surgery is a restrictive/malabsorptive surgical procedure. It is restrictive in the sense that it “restricts” how much food the stomach can hold and is “malabsorptive” in that it affects how food and calories are absorbed into the bloodstream. This combination surgery has the highest success rate for amount of weight lost.

The two most common types of gastric bypass surgery are the Roux-en-Y, and the Single Anastomosis (Omega-loop) gastric bypass . Both of these types of gastric bypass surgery are done laparoscopically (keyhole surgery), using 4-5 small incisions. Your surgeon will help you decide which option is best for you, but generally the Omega-loop gastric bypass is preferred unless you have severe reflux.

In both types of gastric bypass surgery, the surgeon creates a small stomach pouch by dividing the stomach into two using surgical staplers along the upper part of the stomach. A new opening from this pouch is then created, and joined to the small intestine to allow food to exit the pouch.
This prevents food entering the stomach and some of the small intestine (the duodenum and part of the jejunum), and achieves significant calorie restriction as well as some malabsorption. It also causes very beneficial alterations to the hormones made by the gut, as well as making the composition of gut bacteria more healthy (the gut microbiota). Because of these effects the Gastric Bypass is highly effective at treating diabetes, which can be completely reversed in many cases.

Advantages of Gastric Bypass Surgery include:

  • Quick weight loss- most patients lose their weight within 12 months
  • Good long term weight control- studies show continued weight control beyond 15 years post-surgery
  • Patients lose between 60-70% of their excess weight on average
  • Improved health problems associated with severe obesity, especially Diabetes
  • Improved mobility and quality of life

Disadvantages of Gastric Bypass Surgery include:

  • Dumping
  • Anemia
  • Vitamin Deficiencies
  • Revisional surgery for internal hernias causing small bowel obstruction

Intragastric Balloon

gastric-band

This is an endoscopic procedure where a balloon is inserted into the stomach via the mouth and inflated.

It is reserved for patients who do not qualify for weight loss surgery. It is a day only procedure. The intragastric balloon is temporary and needs to be removed in 6 months. The average weight loss is around 15 kg’s. Better results are achieved when done with a multidisciplinary approach.
