Gastric Bypass - Step One
During the belly bypass procedure, the high abdomen is disconnected with a stapler and able with stitches to actualize the new high (proximal) abdomen pouch. The new accessory is the admeasurement of a golf ball, captivation about 20 cc. The accessory is fabricated so baby for two reasons. First, it will eventually amplitude somewhat. By authoritative it actual baby at first, the final admeasurement will still be absolutely restrictive. Second, the high accessory continues to accomplish abdomen acid. The accessory is kept baby to abbreviate the bulk of acerbic that enters the high jejunum and appropriately abbreviate the adventitious of developing an abscess at the stomach.
The lower (distal) beyond allotment of the abdomen is larboard in abode for three reasons. First, it still produces acerbic and pepsin to advice abstract food. These juices biking down the duodenum and into the jejunum to mix with food. Second, if for any acumen a accommodating needs to accept the operation reversed, the abdomen is still there and can be absorbed up again. Please agenda that this is actual rarely necessary. Third, removing the lower allotment of the abdomen would abundantly prolong the anaplasty and accomplish it added dangerous.
The high jejunum is aswell disconnected in alertness for bringing it up to affix to the high abdomen pouch.
Gastric Bypass - Step Two
The allotment of the jejunum that is brought up abaft the colon and lower abdomen accessory is alleged the "Roux limb". (Roux was a Swiss surgeon who developed the accepted technique.) The Roux limb is abutting to the high abdomen accessory application a annular stapler or with a duke sewn technique. The basic band is able area all-important with duke sewn stitches. The aperture amid the accessory and the civil is 1.1cm (less than 1/2 inch) in diameter.
Gastric Bypass - Step Three
The end of the jejunum is absorbed to the ancillary of the Roux limb. Thus, aliment goes down the esophagus into the high pouch. It again goes through the anastamosis into the Roux limb. Digestive juices from the stomach, the liver, and the pancreas biking down the duodenum and jejunum and are added to the aliment that has appear down the Roux limb area the two locations of the baby civil are attached. The aliment and the juices again biking down the baby civil alloyed calm and added assimilation takes place.
Gastric Bypass - Step Four
A gastrostomy tube is occasionally amid through the larboard high belly bank into the lower stomach. The tube is a assurance accessory that allows abdomen juices to escape if the juices can't cesspool calmly into the baby intestine. A lot of patients don't charge the tube, and the accommodation to abode the tube is fabricated at the time of anaplasty based on how apart or bound the tissues are area the baby bowel is absorbed to the Roux limb. The gastronomy can could cause complications, and it is annoying and uncomfortable, so we do not use it routinely. If a gastronomy tube is inserted, it can calmly be removed in the appointment about 3 weeks afterwards surgery.

This diagram shows a accomplished belly bypass operation and includes the academic medical agreement that call the altered parts. These agreement are apparent because they are frequently acclimated in medical online writing that you may apprehend on the web or at the library. The operation is alleged a "Roux en Y Belly Bypass" because the abstraction of bringing up the breadth of baby civil was developed by the Swiss surgeon Roux, the about-face in "Y" shaped, and a lot of of the abdomen is bypassed!
