Splenosis. A cause of massive gastrointestinal hemorrhage

Abstract

Splenosis is the autotransplantation of splenic tissue following surgery or trauma. While it has been reported to cause a number of complications, splenosis is most commonly an incidental finding at laparotomy or on imaging studies. In our study, a case of massive, acute gastrointestinal hemorrhage occurred secondary to splenosis involving the small bowel. While there are several reports of self-limited gastrointestinal hemorrhage secondary to splenosis involving the gastric fundus, we are aware of no reports of massive, acute intestinal bleeding caused by this condition. Splenosis should be considered in the differential diagnosis of gastrointestinal hemorrhage in patients who have experienced prior splenic trauma or splenectomy.
