How Is It Different From Gastric Bypass?

When all other weight loss measures aren’t potent, you have two surgical choices- Sleeve Gastrectomy and Gastric Bypass, both done laparoscopically.

  • Gastric Sleeve is best for patients with BMI >/= 40.
  • Removal of a larger part of the stomach results in lesser food holding capacity.
  • The part of the stomach where ‘Ghrelin’ (the hunger hormone) is made, is removed.
  • Removal of this hunger hormone alters the hunger mechanism.

Just like other surgical procedures, the gastric sleeve has certain risks as well. However, the overall complication rates are low. The level of risks associated with this type of surgery is only upto 5%. [3]Sarkhosh K, Birch DW, Sharma A, Karmali S.

The risks and complications of sleeve gastrectomy include:

1. Internal Bleeding

Prevention/Remedy

  • Use of staples of an appropriate height or size
  • Performing over-sewing of staple lines
  • Sewing by hand
  • Applying pressure before firing staples
  • Staple line reinforcement is strengthening staple lines with bio-absorbable material.
  • Hemostatic agents increase the coagulation properties of blood.

2. Pouch Stretching

Stretched Stomach Pouch After VSG

The stomach pouch starts to expand due to a gradual increase in the diet.
  • Your stomach may grow close to its original size.
  • The stretched pouch sends wrong hunger signals to the brain.

Stricture and Abscess After Bariatric Surgery
An abscess can form after bariatric procedures. It is a pocket of fluid. It develops internally in the abdominal or thoracic cavity. Bacteria infestation can cause infection and pain.

  • According to Sarkhosh K. et al, there are roughly 0.7% chances of contracting an abscess or blister.[3]Sarkhosh K, Birch DW, Sharma A, Karmali S. Complications associated with laparoscopic sleeve gastrectomy for morbid obesity: a surgeon’s guide. Canadian Journal of Surgery.

  • Abdominal pains, fever, and nausea are the main characteristics.
  • It may even cause vomiting.

Signs and Symptoms

  • Fever
  • Redness and heat at the place of incision
  • Increased heart rate
  • Dizziness or light-headedness

Prevention/Remedy

  • Antibiotics and thoracotomy are treatment options
  • Surgically reaching the fluid pocket to drain the fluid followed by antibiotics is another option.

4. Gastric Sleeve Leakage

Sleeve Gastrectomy Leak from Pouch

According to the report, Successful Management of a Gastric Sleeve Leak with an Endoscopic Stent, a Roux-en-Y bypass is riskier.

However, its complications may increase the morbidity and mortality rate. Gastric leak incidences vary from 0.7 to 20%.[3]Sarkhosh K, Birch DW, Sharma A, Karmali S. Complications associated with laparoscopic sleeve gastrectomy for morbid obesity: a surgeon’s guide. Canadian Journal of Surgery.

  • A gastric sleeve leak can delay the recovery.
  • A leak can result in an infection, abscess or blood clots in the lungs.

Signs and Symptoms

  • Fever
  • Increased heart rate
  • Difficulty in breathing or altered breathing

Prevention/Remedy

  • Enteral nutrition, a method of feeding a person through a tube.
  • Proton-pump inhibitors provide prolonged gastric acid reduction.
  • Proton pump inhibitors decrease potential harms caused by the leak.
  • Placing a drain internally.
  • Biological or bio-absorbable glues can be used to stop the leakage.
  • Flexible surgery stents can be used to stop leaking.

5. Stricture

A stricture is a state in which the passage from or to the stomach gets blocked or inflamed. This causes all or some of the food to NOT enter the stomach or intestines. Strictures are common post surgery.

  • They can either be acute or chronic.

Prevention/Remedy

A doctor will treat a stricture with the help of an endoscope. Special tools are attached to the top of this flexible tube with image sensors. A small inflatable balloon is joined to the tip to open or loosen the stricture. [4]Case Report on Successful Management of a Gastric Sleeve Leak with an Endoscopic Stent
