Many people who are contemplating undergoing a gastric bypass want to know what exactly goes on during the procedure itself. While the events of a gastric bypass will vary with every patient, there are certain things that will occur in the same order in every procedure.
For starters, the patient will first get a general anesthesia to cover the four hour procedure. After the anesthesia takes affect and the patient falls asleep, the surgeon will make an incision near the abdomen and start working on the pouch in the stomach. In normal patients, their stomach can bee the size of a football in which the surgeon will make a pocket that will become the usable portion of the stomach that will be about the size of a grade A large egg. This is roughly the equivalent of one cup of food which will be the maximum the patient will be able to intake at any given time. To create this pocket, the surgeon will basically staple the stomach together creating a pocket area.
After making this new usable stomach are, the surgeon will then move on to the small intestines in which he or she will cut the small intestines at the jejunum then take the usable end and attach it to the pouch that was just recently created. The goal of this is to bypass most of the stomach and part of the small intestine in order to reduce the amount of food that can be ingested and digested.
From this point, the surgeon will then take the section of small intestine that was left over and attach it to the section that goes to the pouch which creates a “Y" shaped intestine and allows the digestive fluids of the stomach into the intestines as they were originally doing. This helps the patient in the digestion process of what little bit of food they can ingest. It in turn makes the patient also feel fuller off smaller portions.
Before finishing the work, the doctor will usually feed a tube down the patient's nose and into the new pouch that had just been created in order to keep it free of any matter. By keeping it free of particles for a few days after the surgery has been completed, the patient will also see a faster recovery rate.
The surgeon will then finish off by closing up the incision and sending the patient into the postoperative observation room until you awake.
