Laparoscopic Gastric Bypass
Advantages
• Rapid initial weight
loss
• Higher total average
weight loss .
• Higher rate of comorbidity
resolution
• Over 40 years of
surgical experience
in USA
Disadvantages
• Bigger operation and
somewhat slower recovery.
• Major surgery to reverse
• Possibility of nutritional
problems such as Iron
deficiency anemia and
vitamin B 12 deficiency
• 2-5% chances of ulcers at the
junction of the stomach and
the small bowel
The LAP-BAND System
Advantages
• Lowest mortality rate
• No stomach stapling or
cutting, or intestinal rerouting
• Adjustable
• Smaller operation , easily
reversible
• Lowest operative
complication rate
• Low malnutrition risk
Disadvantages
• Slower weight loss.
• Regular follow-up critical for
optimal results
• Requires more commitment from
the patient.
• Slippage or erosion and injury to
the esophagus or stomach as
possible complications.
• Possibility of mechanical
problems with device, infection
Band intolerance, poor weight
loss may result in Band removal
in about 5% of patients
Laparoscopic Sleeve Gastrectomy is an
alternative to:
• Roux-en-Y gastric bypass
Because:
•
•
•
•
•
Lower risk of deficiencies
No risk of marginal ulcer
No or minimal “dumping”
No risk of intestinal obstruction
Easily converted to bypass for inadequate
weight loss
• Contraindications to bypass (chr.anemia,
Crohn’s disease etc.)
• Comparable long-term weight loss to
Gastric bypass
• Very effective as 1-st stage prior to Gastric
bypass in BMI>60
• Lap Band
Because:
• No risk of system
malfunctioning (slippage,
erosion, infection and etc.)
• No need for adjustment
• No foreign body/plastic
• Contraindications to Lap Band
(connective tissue disorders,
allergy)
• Need to take NSAIDs for
arthritis or heart disease
• Sleeve gastrectomy showed
superior weight loss at 3 years
Laparoscopic Sleeve Gastrectomy
Disadvantages:
• Potential for inadequate weight loss/ weight regain due to
sleeve dilatation
• People with BMI>60 may need 2-nd stage surgery (Gastric
Bypass) to achieve normal weight
• Sweet eaters, grazers, binge eaters have suboptimal results
• Potential complications with long staple line
• Not reversible
• May worsen reflux disease (heartburn)
• Not covered by any insurance
• Will have to take vitamins, B12, calcium, possibly antacids
• Mortality 0-0.5%, complications 2.5%, leaks 1%
Gastric Band Adjustment and
Follow-up
•
•
•
•
•
•
Follow-up for life with bariatric surgeon
Follow-up at 2 and 6 weeks after surgery
First adjustment after 6 weeks
First adjustment in the office if possible or using X-ray
Subsequent adjustments done as needed
Patient-driven adjustment policy:
Despite your best effort (healthy eating and regular exercise) no weight loss for 2-3 weeks in a row
• Follow-up visit every 3 months during 1-2 year
• Annual Band adjustment under X-ray to look for optimal
restriction and to detect early potential problems with the band
