Name of Operation	Gastric Banding	Sleeve Gastrectomy	Gastric Bypass

How is it done?	keyhole surgery	keyhole surgery	keyhole surgery
Modality of Weight Loss	Restrictive only	Restrictive and Metabolic	Restrictive and Metabolic
How does it work?	An inflatable band is placed around the top part of the stomach. This limits the amount of food that can be taken by creating a sensation of fullness and degree of discomfort. Tightness of the band is adjusted by injecting and withdrawing fluid from an access port under the skin. Frequent adjustments are needed at regular intervarls.	The size of the stomach is reduce to a narrow tube by removing the outer 75% of the stomach. This limits the amount of food that can be ingested without creating a point of obstruction thus achieving a normal sensation of feeling full. Also it lowers ghrelin level (a hungar hormone) thus reducing hungar.	The stomach size is reduced to a small pouch and then connected to the small intestine. Another join between the small intestine loops is needed further down. Food bypasses the stomach, duodenum and the first part of the small intestine. Small amount of food can be taken and the ingested food creates a strong hormonal environment that suppresses appetite.
Operating Time	1 hour	2 hours	2-3 hours
Advantages	Removal (though leaves a scar on stomach) No cutting or stapeling needed Low risk of early complications Easy to do	Reduces hungar Achieves normal sensation of being full rather than obstructed No or minimal food intolerance No need for adjustments No foreign body Improved quality of life Improves or cure diabetes Less follow-up is needed "Set and forget" type of operation Easy to live with	Reduces hungar Best long term data Rapid intial weight loss Improves or cure diabetes even before weight loss starts Fixes acid reflux as well
Disadvantages & Complications	Food interlance Teaches patients to have the wrong food Band erosion Band slippage Makes further weightloss operations difficult Tube complications Frequent reflux	Staple line leak Narrowing Acid Reflux (rare)	Staple line leak Narrowing Ulcers Dumping syndrome Serious vitamin defeciency Risk of internal hernias and bowel twisting Need close long term follow-up Risk of developing alcohol or substance abuse
Vomiting	Very frequent	very rare	very rare
Long term need for re-opeartion	About 1 in 5 to 1 in 3 patients will need reoperation	very rare	about 5-10% over ten years
Average Hospital Stay	1 Night	2-3 night	3-4 night
Quality of Life	Poor Many patients can not eat healthy food	Best amonng all weight loss operations	Good Dumping syndrome can be an issue
Average weight loss (Results may vary from person to person)	30-40% of excess weight.	60-70% of excess weight	60-80% of excess weight
My Recomendation	Avoid this operation!	I recommend this operation for most patients	Consider this operation if can not have the sleeve operation or if you have poorly controlled diabetes.
