Weight Loss Surgical Procedures

Our weight loss surgery experts perform:

Gastric Sleeve Procedure


Gastric Sleeve


  • Minimally invasive laparoscopic procedure
  • Promotes weight loss by permanently removing two-thirds of the stomach, promoting a feeling of fullness with smaller amounts
  • Preserves the valve (pylorus) that regulates stomach emptying, slowing the process
  • Patients return to work and activities in about two weeks following surgery


Roux-En-Y Gastric Bypass (RYGB)




  • Alters the digestion process, redirecting food to a surgically created pouch in the stomach and bypassing part of the small intestine
  • A restrictive and malabsorptive (inability to absorb certain fats, proteins and sugars) procedure
  • Bypassing the duodenum (first section of the small intestine) prevents calorie and nutrient absorption, resulting in weight loss
  • Produces approximately two-thirds of excess weight loss within two years


Weight Loss Surgery Revisions

Revision generally are performed because of a complication from a previous bariatric surgery, including bypass, sleeve, adjustable-band or vertical-banded gastroplasty. Examples include:

  • An adjustable band that has eroded or slipped. Or the patient no longer can tolerate solid foods. The surgeon would remove the band and convert to a sleeve or bypass
  • A patient develops a complication such as ulceration or strictures. The surgeon may have to revise the anatomy
  • A patient with a sleeve develops severe gastroesophageal reflux disease (GERD) that medications cannot resolve. The surgeon would convert the sleeve to a bypass
  • A patient develops maladaptive eating and weight regain. The surgeon would revise or convert to another procedure
