One of the potential risks of Roux en Y Gastric Bypass and the Sleeve Gastrectomy is a staple line leak. Here, you’ll learn more about why and how these occur, what they mean, and what is the likelihood of developing this complication.
In a Roux En Y Gastric bypass, when the surgeon attaches the small intestine to the large intestine or the small intestine to the stomach, the connection is called an anastomosis. In both a Sleeve Gastrectomy and a Roux En Y Gastric Bypass, staples are used as a temporary “glue” to create a watertight connection of these surgical areas. Then, over time, the body’s healing power takes over for the staples to create a seal over the staples. If the body’s healing power does not form a complete seal, or if the staples come apart (dehisce), then leakage of fluid from within the bowel or stomach occurs and it is called a staple line leak. This is one of the more serious potential risks of Sleeve Gastrectomy and Roux En Y Gastric Bypass surgery. Fluid from the GI tract that contains bacteria, then leaks into the abdomen (where it doesn’t belong), and can cause a serious infection which is accompanied by much swelling, a rapid pulse rate, fevers, and sometimes can form an abscess. This complication, although quite rare, is always a very serious one.
