Procedure Details

Non-surgical procedure that limits the food carrying capacity of the stomach.

Laparoscopic (keyhole) procedure in which an adjustable band is placed around the stomach to limit food intake.

Laparoscopic (keyhole) procedure in which 75% of the stomach is removed.

Laparoscopic (keyhole) procedure which involves bypassing part of the stomach and small intestine.

How it works

Restrictive effect of balloon

Restrictive effect of band

  • Restrictive effect of a narrow sleeve of stomach
  • Immediate metabolic / hormonal effects after surgery
  • Restrictive effect of small stomach pouch
  • Immediate metabolic / hormonal effects after surgery
  • Mildly reduced absorption of nutrients

Reversibility

Reversible and temporary (6 months only)

Reversible

Irreversible

Reversible, but difficult

Operating Time

15 to 30 min

35 to 45 min

40 to 60 min

60 to 90 min

Advantages

  • No surgical incisions or cutting is involved.
  • Shorter hospital stay and recovery time
  • No resection of stomach
  • No alteration in gut anatomy
  • Low risk of early post-operative complications
  • Low risk of malnutrition / vitamin deficiency
  • No implant device in the body
  • Less follow-up reviews required
  • Good at improving/curing type II diabetes
  • Lower long-term complications than gastric bypass
  • Better weight loss efficacy than gastric band and sleeve gastrectomy
  • Higher rate of resolution / improvement of type II diabetes than band / sleeve
  • Good option for moderate / severe acid reflux

Risks/ Complications

  • Nausea and vomiting
  • Abdominal pain
  • Heartburn/reflux disease
  • Deflation of balloon
  • Gastric/duodenal ulcers
  • Band or port infection
  • Band slippage
  • Band erosion into stomach
  • Food intolerance
  • Acid reflux
  • Oesophageal dilatation
  • 10-20% risk of requiring corrective surgery
  • Bleeding
  • Acid reflux
  • Narrowing/twisting/angulation of stomach tube
  • Staple line leak
  • Dumping syndrome
  • Bleeding
  • Staple line/anastamotic leak
  • Ulcer/stricture at anastamosis
  • Internal hernia
  • Vitamin deficiencies

Duration of Hospital Stay

You can return home on the same day.

1 to 2 days

3 to 4 days

3 to 4 days

Time away from work

2 to 3 days

1 week

1 to 2 weeks

1 to 2 weeks

Eating Quality

Good

Some food can get stuck if not properly chewed

Takes several weeks to progress to solids after surgery, but good eventually

Good, but some foods may cause dumping syndrome

Excess weight loss

Approximately 15-20% weight loss

Approximately 30-40% weight loss by 18 months

Approximately 50-60% weight loss by 12 months

Approximately 60-70% weight loss by 12 months

Follow-up

Intragastric balloon is left in place for 6 months and then removed.

Regular reviews every month for the first 6-12 months until optimal amount of fluid in band is achieved and then every 3-6 months afterwards.

Regular reviews every 3 months for the first year and then every 6 months for the second year

Regular reviews every 3 months for the first year and then every 6 months for the second year
