Gastric Sleeve Benefits / Risks Denver


Weight loss surgery is not without risk. The risks of surgery must be weighed carefully against the benefits of weight loss. Any major surgery carries risks of anesthesia, bleeding, infection, blood clots, pulmonary embolism – any of these can be minor or very serious including death. In addition, gastric bypass and sleeve gastrectomy surgery carries specific risks including, but not limited to, hernia, gallbladder problems, bowel obstruction, leak from staple lines and narrowing along the staple lines or at the anastomosis (where the bowels are hooked back together in the gastric bypass). LAP-BAND surgery also carries specific risks including band slippage, band erosion and band or port issues that require surgery to fix or replace.

Lifelong supplementation of vitamins and minerals must be taken to prevent nutritional deficiencies such as anemia and osteoporosis. Women of childbearing age must avoid becoming pregnant during the first 1-2 years after gastric bypass surgery. Nutritional deficiencies during the rapid weight loss period after surgery could harm the developing baby. During you consultation with Western Surgical Bariatric Center, you will carefully review the risks weighed against the benefits of surgery for your particular situation.

Please refer to the Allergan website for a full list of the risks associated with the LAP-BAND® procedure.

Listed below are the consent forms that are used for each of the bariatric procedures, along with an additional information of the risks involved with bariatric surgery. Please review these forms carefully prior to surgery.


Weight loss surgery is not right for you if: (this is a partial list of contraindications – contact your bariatric surgeon for full details)

  • You have an inflammatory disease or condition of the gastrointestinal tract, such as ulcers, severe esophagitis, or Crohn’s disease.
  • You have severe heart or lung disease that makes you a poor candidate for surgery.
  • You have some other disease that makes you a poor candidate for surgery.
  • You have a problem that could cause bleeding in the esophagus or stomach. This might include esophageal or gastric varices (a dilated vein). It might also be something such as congenital or acquired intestinal telangiectasia (dilation of a small blood vessel).
  • You have portal hypertension.
  • Your esophagus, stomach, or intestine is not normal (congenital or acquired). For instance you might have a narrowed opening.
  • You have or have experienced an intra-operative gastric injury, such as a gastric perforation at or near the location of the intended band placement.
  • You have cirrhosis.
  • You have chronic pancreatitis.
  • You are pregnant. (If you become pregnant after the BioEnterics LAP-BAND® System has been placed, the band may need to be deflated. The same is true if you need more nutrition for any other reason, such as becoming seriously ill. In rare cases, removal may be needed.)
  • You are addicted to alcohol or drugs.
  • You are under 18 years of age.
  • You have an ongoing infection that could contaminate the surgical area.
  • You are on chronic, long-term steroid treatment.
  • You cannot or do not want to follow the dietary rules that come with this procedure.
  • You might be allergic to materials in the device (lap band patients).
  • You cannot tolerate pain from an implanted device.
  • You or someone in your family has an autoimmune connective tissue disease. That might be a disease such as systemic lupus erythematosus or scleroderma. The same is true if you have symptoms of one of these diseases.

As with any surgical procedure, it is very important to understand all of the risks and benefits associated with the procedure. Your personal consultation with our team of experts will include a discussion about the pros and cons of each type of bariatric procedure. This will give you the information that you need to make an informed decision about your bariatric procedure. Call now to set up your personal consultation with one of our bariatric surgeons.
