Why Surgery?
Diet and exercise only works for 1 in 20 (5%) people who are obese
Surgery is safe and effective Improves co-morbidities Benefits of surgery outweigh the risks
for the morbidly obese risks of surgery risks of staying morbidly obese

morbidity documented dietary attempts ineffective

Laparoscopic Roux-en-Y(Minimally Invasive)
Six small puncture wounds (1/4 to ½ inch)
A laparoscope, connected to a video camera, is inserted through the small incision into the abdomen
![Page 32: Laparoscopic Bariatric Surgery. Bariatric Surgery Greek baros (weight) + iatrike (medicine, surgery) A field of medicine encompassing the study of overweight,](https://reader030.fdocuments.net/reader030/viewer/2022013012/56649ea15503460f94ba51eb/html5/thumbnails/32.jpg)
Advantages of Laparoscopy
Fewer wound complications infection, hernia
Probably fewer cardiac and respiratory complications
Less pain and faster recovery Surgeon has better view of the
anatomy
![Page 33: Laparoscopic Bariatric Surgery. Bariatric Surgery Greek baros (weight) + iatrike (medicine, surgery) A field of medicine encompassing the study of overweight,](https://reader030.fdocuments.net/reader030/viewer/2022013012/56649ea15503460f94ba51eb/html5/thumbnails/33.jpg)
Roux-en-YOpen vs. Laparoscopic
Procedure
LAPAROSCOPIC Hospital stay is 1 to 3 days.
Patients usually return to work in 10 to 14 days.
Technically more demanding for the surgeon
OPENHospital stay of about 5 days.
Return to work in about 4 weeks.
More painful
Greater risk of infection

Most patients who have had gastric-bypass surgery begin . . .
A soft diet after the first week A regular diet at one month Nutritional and psychological
counseling A daily multi-vitamin with iron for life Weekly sublingual vitamin B12 for life

Post-OperativeMaintenance
First post-operative visit is usually 7-10 days following surgery
Office visits are scheduled at 1, 3, 6 and 12 months after surgery, and yearly thereafter
Lab work is performed at all visits after the 1st postoperative visit

Post-Operative
Most patients lose up to and beyond 80% of excess weight
…and keep it off.

Pre-Operative Process
Medical History
You will need a detailed account of efforts to achieve weight loss by non-surgical methods.
Lists of specific comorbidities need to be identified.
Your current health status will need to be evaluated
![Page 44: Laparoscopic Bariatric Surgery. Bariatric Surgery Greek baros (weight) + iatrike (medicine, surgery) A field of medicine encompassing the study of overweight,](https://reader030.fdocuments.net/reader030/viewer/2022013012/56649ea15503460f94ba51eb/html5/thumbnails/44.jpg)
Pre-Operative Process
Supporting Documentation
You will need a brief letter from any physicians that have treated any weight-related health conditions.
Any documentation from physicians stating the previous weight-loss efforts that you have made can be very valuable.

Pre-Operative Process
Medical Testing
Further medical testing may need to be completed in order to further clarify any existing comorbidities
A psychological evaluation may also be needed
![Page 46: Laparoscopic Bariatric Surgery. Bariatric Surgery Greek baros (weight) + iatrike (medicine, surgery) A field of medicine encompassing the study of overweight,](https://reader030.fdocuments.net/reader030/viewer/2022013012/56649ea15503460f94ba51eb/html5/thumbnails/46.jpg)
Pre-Operative Process Insurance Request
Depending on the type of health care benefits, a request is made for coverage of the surgery from the patient, as well as the surgeon.
If the Request is Denied
Some insurance companies will initially deny a request for coverage. An appeal from the patient can be made or the patient can choose to seek legal advice.

Frequently Asked Questions
Can gastric-bypass surgery be reversed?
Yes. The procedure is intended to be a permanent change, but because the stomach is bypassed, not removed, surgeons can undo the pouch.

Frequently Asked Questions Continued…
Will I need plastic surgery?
Many factors influence the need for plastic surgery, for example starting weight, the amount of weight lost, location of the excess weight and age. The younger patients have a greater amount of skin elasticity and therefore are less likely to need plastic surgery.
