Gastric Sleeve Procedure - Gastric Bypass Lap Band Surgery, Mexico

Roux-en-Y Gastric Bypass (RNY)

Roux en Y (RNY) is a bariatric procedure that staples off a 1-ounce stomach pouch at the upper portion of the stomach. A section of small bowel is then attached to the pouch via a small opening, which simulates the pyloric valve.

RNY evolved from other bariatric surgeries to provide more consistent and successful weight loss. The small upper pouch is completely separated from the distal stomach which is left in place. A "Y" shaped segment of small bowel is attached to the pouch with a narrow opening. This delays the mixing of food and digestive juices from the distal stomach resulting in poorer absorption of calories and nutrients. This both restricts food intake and interferes with absorption resulting in more consistent weight loss. 80% of patients lose at least half their excess weight with the RNY procedure.

The RNY averages a 3-day hospitalization with a return to full activity in 7-10 days. A liquid protein and soft diet is suggested for 3 weeks post op.

Advantages:

Excellent weight loss results; near 85-90% of excess weight within 12-18 months after surgery.
Allows patients to eat almost normally, with a small probability of feeling nauseous, vomits or a "food stuck" sensation (called dysphagia).
Due to the dramatic weight loss, this surgery diminishes the diseases associated with obesity, and may even allow the patient to stop medication.
If this surgery is performed laparoscopically, there is significantly less pain and a faster recovery.
This procedure usually maintains weight loss for more than 15 years, even if patients eat high-calorie foods.
85% of patients report significant weight loss.

Risks:

Because stomach resections and intestinal connections are performed, the probability of intestinal content leaks is possible in the first few days after the operation. This is called 'fistula' and happens in approximately 1% or 2% of the cases.
Longer recovery time in the hospital than other procedures (somtimes around four days), because it is necessary to pay special attention to fistula problems and other potential complications.
Requires taking vitamins and calcium supplements permanently after the surgery. In addition, it may require periodic supplements of B12 and iron.
The probability of diarrhea after the surgery is from 1% to 3%, but this can be corrected with diet and medicine adjustments. Generally, if this problem appears, it will be within the first 6 months.
The patient should visit the doctor three or four times during the first year, with controlled examinations. Then, annual visits are sufficient to watch for possible lack of vitamins or minerals.
