Sleeve Gastrectomy Discussion

Sleeve gastrectomy has been performed laparoscopically in bariatric centres as a stand alone procedure for around 5-8 years. The reason for the first sleeve gastrectomies was to take some initial weight off very large individuals so that the second stage of their operation (biliopancreatic diversion with duodenal switch) could be safely performed.

It was found, however, that the sleeve surgery itself was associated with significant weight loss and therefore the second stage was often not required. More recently surgeons have switched to making the residual stomach smaller than the original sleeves were.


Standard Five port Sleeve Gastrectomy




The current popularity of the sleeve is because of the following:

  • The reliability of weight loss is excellent
  • The rate of weight loss is often faster than with gastric banding
  • There is usually substantial hunger suppression after sleeve surgery
  • The risks of surgery are less than for gastric bypass and it can be done with a keyhole approach almost all the time
  • There is usually little in the way of food intolerance and vomiting is not common
  • You are less likely to have ongoing issues which may require reoperations (e.g. slipped band) than for gastric banding or bypass.

Sleeve Gastrectomy 


The down-sides of sleeve gastrectomy are…

  • It is entirely irreversible and involves permanent removal of around three quarters of an otherwise perfectly normal organ
  • There is very little published information beyond five years of follow-up for this procedure
  • Although results are usually good at the two to three year mark, it is unclear at this stage how many people may regain some or even all of their weight in the long term.
  • If weight regain does occur, conversion to gastric bypass may be an option, however this is a big undertaking and leaves even less viable stomach in the patient
  • Very occasionally (<5%) patients have ongoing issues with vomiting and food intolerance after sleeve gastrectomy. This may be due to a narrowing or twist in the tube and is typically quite difficult to fix
  • Leaks can occur from the staple line in up to 2% of cases. These can be difficult to treat and require many weeks or months in hospital
  • Some people get acid reflux after sleeve gastrectomy or worsening of pre-existing reflux. It is normally well controllable with medication.

NB: for Sleeve Gastrectomy patients who may have had relatively poor results or regained weight, the loop duodenal switch revision or SIPS surgery may be an option to get things back on track
