Gastric Band
What is Laparoscopic Adjustable Gastric Banding?
Laparoscopic adjustable gastric banding, commonly known as Lap-Band surgery, is a weight-loss procedure that involves placing an adjustable silicone band around the upper part of the stomach.
The band is connected to a small access port beneath the skin, allowing its tightness to be adjusted using saline injections.
Unlike sleeve gastrectomy or gastric bypass, gastric banding does not involve removing part of the stomach or altering the intestinal anatomy.
Is Gastric Band Surgery still recommended?
Gastric banding was once a popular weight-loss operation in Australia. However, its use has declined considerably as longer-term studies have demonstrated important limitations.
Although gastric banding can produce meaningful weight loss in selected patients, research has shown that it generally results in less weight loss than sleeve gastrectomy or gastric bypass.
It is also associated with a higher likelihood of requiring further procedures or surgery over time.
At Evolve Bariatrics, Dr Adrian Teo does not routinely recommend gastric banding as a primary weight-loss procedure. Other bariatric procedures, including sleeve gastrectomy and gastric bypass, are generally preferred following an individual assessment.
Why has Gastric Band Surgery become less popular?
Several factors have contributed to the decline in gastric band surgery.
1. Less predictable long-term weight loss
Gastric banding generally achieves less weight loss than sleeve gastrectomy or gastric bypass. Some patients experience inadequate weight loss or significant weight regain over time.
2. Long-term complications
Complications associated with gastric bands may include:
- Difficulty swallowing (dysphagia)
- Persistent regurgitation or acid reflux
- Band slippage or pouch enlargement
- Oesophageal dilatation and motility problems
- Band erosion into the stomach
- Problems with the adjustment port or connecting tubing
- Inadequate weight loss or weight regain
3. Higher likelihood of further surgery
Long-term studies have demonstrated that a substantial proportion of patients eventually require band adjustment procedures, revision, removal or conversion to another bariatric operation.
4. Ongoing maintenance
Gastric bands require lifelong follow-up, including periodic adjustments and monitoring for complications.
What if I already have a Gastric Band?
Patients with an existing gastric band do not necessarily require removal if the band is functioning well, weight loss is satisfactory and there are no complications.
However, specialist assessment may be appropriate if you experience:
- Persistent reflux, regurgitation or vomiting
- Difficulty swallowing or food intolerance
- Inadequate weight loss or significant weight regain
- Pain or discomfort associated with the band
- Suspected band slippage, erosion or other complications
Can a Gastric Band be removed or converted to another procedure?
Yes. Depending on the circumstances, treatment options may include band adjustment, band removal, or conversion to another bariatric procedure.
Common revisional options include sleeve gastrectomy and Roux-en-Y gastric bypass.
The most appropriate approach depends on several factors, including previous weight loss, reflux symptoms, oesophageal function, existing band complications and individual health considerations.
Revisional bariatric surgery can be more complex than primary surgery and requires careful assessment.
Choosing the right Weight-loss Procedure
At Evolve Bariatrics, treatment recommendations are based on individual medical circumstances, weight-loss goals and the available scientific evidence.
Dr Adrian Teo is a Specialist Upper Gastrointestinal and Bariatric Surgeon who can discuss contemporary surgical weight-loss options and assess patients experiencing problems with previous bariatric surgery.
A consultation can help determine whether ongoing observation, medical management or revisional surgery is appropriate.
