Bariatric Surgery (Weight loss surgery):
Laparoscopic Roux-en-Y Gastric Bypass
(Stomach Stapling)
General description
Laparoscopic Roux-en-Y Gastric Bypass (also known as stomach stapling) is a bariatric surgery procedure considered the golden rule by many. It has a restrictive and malabsortive side to it:
- Surgical stapling limits gastric intake. Weight loss results from reduced consumption.
- Intake of nutrients is limited due to surgical change in the biliar and pancreatic secretions and their union with food.
All patients who undergo bariatric surgery must be aware of all pre and post surgical requirements.

Technical description
Procedure Laparoscopic Roux-en-Y Gastric Bypass reduces the size of the stomach through surgical stapling. This type of weight loss surgery shrinks the stomach leaving a reservoir of approximately 30ml. The small intestine is divided to form a y and affixed to the gastric reservoir so food follows an altered course.
Weight loss surgery of this nature involves gastrointestinal cuts and unions that could eventually cause leaks. There is risk involved in this type of surgery.
After surgery, the patient must follow a special diet and vitamin intake to reduce weight properly.
Hospitalization Laparoscopic Roux-en-Y Gastric Bypass requires 4 nights hospitalization.
Time Between an hour and a half and four hours.
