Zusammenfassung
Wir berichten über zwei Patienten mit oberer gastrointestinaler Blutung bei duodenalen Angiolipomen sowie deren endoskopischer Diagnostik und Therapie. Bei beiden fand sich eine Blutung aus einem gestielten Tumor. Die Diagnose und definitive Therapie erfolgten durch endoskopische Schlingenabtragung. Nachdem bei einem Patienten die Blutung aus dem resultierenden Mukosadefekt durch Injektionstherapie gestillt wurde, war der weitere Verlauf bei beiden unauffällig. Ein Angiolipom im Kolon bei einem der Patienten wurde ebenfalls durch Schlingenpolypektomie behandelt. Gastrointestinale Angiolipome sind überaus selten. Duodenale Angiolipome können wie Lipome zu relevanten gastrointestinalen Blutungen führen; sie können durch Standardpolypektomietechniken erfolgreich behandelt werden.
Abstract
We report on two patients with upper gastrointestinal bleeding owing to duodenal angiolipomas, and their endoscopic diagnosis and therapy. In both cases the bleeding source was a pedunculated tumour. Diagnosis and definitive therapy was made by endoscopic snare polypectomy. After stopping the bleeding from the mucosal defect by injection therapy in one patient, the further course was uneventful in both. A colonic angiolipoma in one of the patients was also treated by polypectomy. Gastrointestinal angiolipomas are exceedingly rare, however, these case reports show that duodenal angiolipomas do exist and that they, as lipomas, may lead to substantial gastrointestinal bleeding and may be treated successfully by standard polypectomy techniques.
