Dieulafoy′s Lesions of the Rectum: A Rare Cause of Lower Gastrointestinal Bleeding

open access: yesCanadian Journal of Gastroenterology and Hepatology, Volume 15, Issue 8, Page 541-545, 2001., 2001
Dieulafoy′s lesions located outside of the stomach are rare occurrences. Lesions found within the colon typically present with painless, massive hematochezia (ie, greater than 5 U). If they can be accurately located, endoscopic therapy in the form of adrenaline injection, sclerotherapy or cauterization appears to have long term success.
