The Gastric Sleeve

Operation technique: The Gastric Sleeve (also known as Sleeve Gastrectomy) is an operation that involves removing three quarters of the stomach. After the operation the patient is left with a small stomach tube that is around 2cm in diameter and that has a volume of around 100mls. Food is digested in the same way as before, however the volume of the stomach is significantly reduced.

Operation duration: The operation takes around one hour.

Hospital stay: Most patients only require a 1 – 2 night stay in hospital following the operation. At The Spire Washington you will have your own large private room with TV, Window, Armchair, Wardrobe and En-suite.

How does the Gastric Sleeve work?

Removal of the hunger hormone: This operation works mainly by supressing the appetite and the hunger of the patient. The hunger hormone ghrelin is produced by the part of the stomach that is removed during sleeve gastrectomy. And as a result, the changes to these gut hormones aid the rapid weight loss experienced shortly after the Gastric Bypass in the first 6-9 months. 

Reduction in stomach size: The stomach reduction also means that you feel full after eating a small meal and cause you to feel less hungry between meals. This causes you to absorb fewer calories and as a result lose weight.

Average weight loss of 30%: Gastric Sleeve surgery achieves average total weight loss of around 30%. For example, if your weight now is 20 stone, we expect it to be around 14 stone after gastric bypass. Many patients experience rapid weight loss during the initial 6-9 months after their operation and on average people lose around 30% of their weight within 2 years.

Health improvement: In addition to weight loss, the bypass improves many weight loss conditions including: Type 2 diabetes, High cholesterol, High blood pressure, Risk of stroke, Reflux, Polycystic ovaries and Sleep apnoea. 

Increased energy: After recovery people find they are able to enjoy exercise and physical activity, building fitness, stamina and enjoy increased energy.

Recovery after Sleeve Gastrectomy

Healing time: Private Gastric Sleeve surgery is carried out as a key hole (laparoscopic) procedure using five small cuts in the skin about 1cm wide. This means that in addition to achieving excellent weight loss, the recovery is quick (most patients stay in the hospital for 1 night only), the pain is minimal, and the risk of post-surgical hernias is reduced. Gastric Sleeve surgery has a low risk of complications and is a safer operation than many other operations that are performed routinely.

Pain relief: After discharge most patients only require paracetamol for pain relief.

Bathing after surgery: Taking a bath or swimming must be avoided for two weeks after surgery (showering is permitted immediately following surgery).

Driving after surgery: Patients can return to driving after around 2 weeks following the bypass as long as you are able to look over your shoulder and perform an emergency stop without pain. 

Returning to work: Most patients are able to return to desk based work within 2 – 3 weeks of their operation. Those with more physical jobs may need to think about the following restrictions after surgery. Injury should be avoided and Gastric Sleeve patients should avoid lifting anything heavier than 5kg in weight for six weeks.
