Bleeding is one of the potential complications of Lap Band Surgery, Roux En Y Gastric Bypass Surgery, and The Sleeve Gastretomy. Bleeding can be classified as either acute bleeding or a GI bleed. Although both of these are rare, they are important to know.
In acute bleeding, blood loss can be from the fresh staple lines that were made during a gastric bypass or the sleeve gastrectomy, from inadvertent injury to the spleen or injury to one of the many blood vessels located in and around the surgical area. Bleeding from these various sources can usually be stopped but in extremely rare cases, as in an injury to the spleen, the spleen may have to be removed to stop the bleeding. In the extremely rare event of having to remove the spleen, a person can live without a spleen but will have to receive a vaccine after the spleen is removed.
