Karina Grooteman Disease characterization and treatment of gastrointestinal angiodysplasias

Angiodysplasias are vascular malformations in the mucosa of the digestive tract. These abnormal blood vessels tend to bleed easily, especially in older people with kidney or heart diseases. Karina Grooteman investigated triggers that cause the bleeding, current and new therapeutic options. She discovered that patients with angiodysplasias in the stomach and small bowel bleed more frequent than in the colon. Patients with anemia due to the gastrointestinal bleeding had a decreased quality of life. She also found that there is a high variation in treatment strategy between gastroenterologists. There might be room for improvement to treat the abnormal blood vessel during the first endoscopic investigation. For patients with severe bleeding and frequent blood transfusions, octreotide decreases the need of blood transfusions.
