Laparoscopic gastric banding, or Lap band surgery, is rarely performed today in modern bariatric surgery due to higher re-operation rates. This procedure is reserved in whom the other procedures, like sleeve gastrectomy and mini gastric bypass, are contraindicated.
Laparoscopic Adjustable Gastric Banding is a type of minimally invasive weight loss surgery that involves wrapping a band around a part of the stomach to reduce its size and limit the capacity of food intake.
The band used is an adjustable, inflatable silicone ring which is placed around the stomach to divide it into 2 parts: a small upper pouch, and a larger lower pouch. The smaller upper pouch, fills up quickly with food giving a feeling of fullness or satiety. This limits excessive intake of food and promotes weight loss.
EXPECTED WEIGHT LOSS: 15-20% of your weight
Lap-Band surgery is performed laparoscopically under general anaesthesia. Dr Martin makes a few small incisions and inserts a laparoscope which enables him to see the internal structures of the abdomen on a monitor with images sent from the camera. The band is then secured and fastened with sutures. The band is inflated with sterile saline until it attains the correct diameter to optimally constrict the stomach. In order to adjust the band, an access port connected to the band is placed under the skin of the abdomen. Dr Martin then loosens (deflate) or tightens (inflate) the band by injecting or aspirating saline solution as needed. Finally, the incisions are closed.
- Fewer complications
- Quicker recovery
- Overnight hospital stay
- Requires regular adjustments
- Band can slip or move and block the stomach
- Tubing can leak
Dr Martin recommends this procedure when the risks of gastric sleeve or stomach bypass are too great for the individual patient due to conditions such as portal hypertension, cirrhosis of liver, coagulation, severe renal cardiac or immune compromised patients.
After lap band surgery:
- you will stay in hospital for 1 night
- you will have pain relieving weight loss medications to keep you comfortable
- you will be given instructions to follow regarding wound care, diet and activity
- you will take Somac or Nexium for 4 weeks and then stop if reflux free
- Keep the incision area clean and dry
- Avoid strenuous exercises and lifting heavy weights for 2 weeks
- Sip water throughout the day to prevent dehydration
- Follow the diet regimen given to you by the dietitian
- Follow an exercise program to maintain weight loss
As with any major surgical procedure, Lap band surgery also carries some risks to the patient, including:
- Internal bleeding
- Nausea and vomiting
- Band slippage or deflation
- Oesophageal dilation
- Erosion of stomach
- Obstruction of stomach
- 5% yearly risk of reoperation
