What are the risks of weight loss surgery?

What are the risks of weight loss surgery?

Serious complications can occur with any surgery; fortunately complications remain extremely low.  Specific and proper patient preparation, selection along with Dr. Feng’s experience markedly reduces the risk and complications of weight loss surgery.

Risks of LAP-BANDŽ System Procedures
Risks & Benefits of Weight Loss SurgeryRisks of LAP-BANDŽ System or REALIZE™ Adjustable Gastric Band Procedures

  • Nausea/vomiting
  • Food getting stuck, needing deflation of band
  • Overstretched, abnormally widened esophagus
  • Excessively tightened
  • Infection
  • Inadequate weight loss
  • Weight regain
  • Device malfunction
  • Balloon, tube access port breakage
  • Access port flipping over
  • Slippage of down along the stomach causing vomiting
  • Erosion of the silicone band creating a hole in the stomach
  • Gallstones

Advantages of LAP-BANDŽ System or REALIZE™ Adjustable Gastric Band Procedures

  • Only procedure that can be reversed if necessary
  • Usually done laparoscopically (minimally invasive)
  • Easier to perform and generally safer than other weight loss options
  • Outpatient surgery
  • Results in fewer nutritional deficiencies

Risks of Vertical Gastrectomy Procedure
Risks of Vertical Sleeve Gastrectomy Procedure

  • Leakage
  • Nausea/vomiting
  • Acid reflux
  • Weight regain
  • Rarely, allows for second surgery for more weight loss
  • Gallstones

Advantages of Vertical Sleeve Gastrectomy Procedure

  • Usually done laparoscopically (minimally invasive) with robotic-assistance in patients.
  • Allows patients of any weight, including the super super obese and high risk patients, to undergo surgery with small incisions
  • Rapid weight loss
  • Patients do not experience diarrhea or significant “Dumping Syndrome” symptoms
  • The portion of the stomach producing hunger-stimulating hormones (Grehlin) is removed
  • The smaller stomach maintains normal function with no rearrangement of the intestines, reducing risks of protein and vitamin deficiency and thus no significant "Dumping Syndrome" symptoms
  • Minimal patient effort to lose and maintain weight loss
  • Better weight loss than the Adjustable Gastric Band procedures
  • Safe in patients needing long term aspirin, NSAID such as Motrin, Advil, naprosyn, steroid use

Risks of Roux-en-Y Procedure
Risks of Roux-en-Y Gastric Bypass Procedure

  • Leakage
  • Infection
  • Vitamin and mineral deficiencies
  • Anemia
  • Osteoporosis
  • Strictures at the stomach pouch connection to intestine
  • Intestinal ulcers at margin of connnection to stomach pouch
  • Bowel Obstruction from internal intestinal scars, internal hernias or telescoping small intestine (intussusception)
  • Dumping syndrome
  • Gallstones
  • Possible nesideoblastosis disease causing severe hypoglycemia issues
  • Combined operations are more likely to lead to complications then restrictive operations
  • Weight regain

Advantages of Roux-en-Y Gastric Bypass Procedure

  • May be more effective in in some studies in improving obesity-related health problems than some restrictive procedures
  • Rapid weight loss
  • The portion of the stomach producing hunger-stimulating hormones is bypassed, and thus less hunger is experienced in the first year after surgery but hunger usually returns after about 9 months after surgery
  • Better weight loss than the Adjustable Gastric Band procedures

Risks of Duodenal Switch Procedure
Risks of Duodenal Switch Procedure

  • Excessive or too much weight loss
  • Leakage
  • Infection
  • Diarrhea
  • Anemia
  • Bowel obstruction
  • Gallstones
  • More vitamin and mineral deficiencies
  • Abdominal hernia
  • Combined and more malabsorptive operations are more likely to lead to complications then restrictive operations
  • Inadequate weight loss
  • Weight regain

Advantages of Duodenal Switch Procedure

  • Patients are able to consume larger meals
  • Rapid weight loss
  • Stomach function remains intact with normal stomach emptying, and thus “Dumping Syndrome” seldom occurs, like the sleeve gastrectomy
  • The portion of the stomach producing hunger-stimulating hormones is removed, like the sleeve gastrectomy
  • Better weight loss than the Adjustable Gastric Band procedures
  • Safe in patients needing long term aspirin, NSAID such as Motrin, Advil, naprosyn, steroid use
