Laparoscopic Gastric BypassLaparoscopic Gastric Bypass
Weight lossWeight loss
• About 100 lbs, or about 65% to 70% EBW and about 35% of the BMI.
• Weight loss generally levels off in 1 to 2 years, and a regain of up to 20 lb or more is common in the longterm
Operative mortality (death) and morbidity Operative mortality (death) and morbidity (injury)(injury)
• Overall (30 day) mortality for gastric bypass when performed by skilled surgeons is about 0.5%0.5%– High blood pressure, high BMI, bowel leak, blood clots to High blood pressure, high BMI, bowel leak, blood clots to
lunglung
• Overall Operative morbidity (eg, pulmonary emboli, anastomotic leak, bleeding, wound infection) is 5%5% – Leak up to 5%Leak up to 5% - breakdown in the staple lines from cutting and
formation of connections bwt intestine and stomach pouch
– Bleeding up to 4%Bleeding up to 4% - this occurs at the staple lines after the stapling device cut the bowel
– Blood clots up to 1%Blood clots up to 1% - but death from this complication accounts for 30-50% of patients
Longterm complicationsLongterm complications• internal hernias (bowel obstructions)
– 1-10%1-10%– More common in laparoscopic technique– Difficult to diagnose with routine xrays leading to high rate of
reoperation to make diagnosis• stomal stenosis – opening to gastric pouch becomes too
tight– 3-12%3-12%– Treatment require using a ballon to stretch the opening
• marginal ulcers - breakdown of connection between small intestine and gastric pouch– 1-16%1-16%– Alcohol and cigarrette smoking are major risk factor– NSAIDS contraindicated in bypass pts
Longterm complicationsLongterm complications
Nutritional Deficiencies– Permanent mineral and vitamin supplement for the
rest of natural life!! • Can be very expensive cost out of pocket for patients!

Gastric Banding Contraindications
• Inflammation of the digestive tract, including ulcers, severe esophagitis, or Crohn’s disease
• Severe heart or lung disease• Upper digestive tract bleeding conditions due to enlarged or
fragile veins• Portal hypertension• Abnormal digestive tract anatomy• Cirrhosis of the liver• Chronic pancreatitis
Situations where the risks are greater than the benefits that would be gained from surgery are contraindications. These include:

Gastric Banding Contraindications – con’t.
• Infection of any type, anywhere in your body• Known allergies to the implant materials• Using steroids for a long period of time or within 15 days of
surgery• Currently pregnant• Younger than 18 years of age• Unwilling to make significant changes in eating and behavior

Risks Associated with Gastric Banding
• Migration of implant (band erosion, band slippage, port displacement)
• Tubing-related complications (port disconnection, tubing kinking)• Band leak• Esophageal spasm• Gastroesophageal reflux disease (GERD)• Inflammation of the esophagus or stomach• Port-site infection
Note: Complications may result in re-operations. These complications are not usually life- threatening. Refer to the Realize™ Patient Guide for a full description of the risks and side effects.
