Endoscopic Ultrasound-Guided Coil Embolization of Refractory Rectal Dieulafoy Bleeding.

Hematochezia due to recurrent bleeding from rectal Dieulafoy can be challenging for endotherapy. We report the first case of successful endoscopic ultrasound-guided coil embolization of a feeding arteriole to the peripheral Dieulafoy vessels in the region of a colorectal anastomosis. The patient presented with recurrent lower gastrointestinal hemorrhage despite multiple previous conventional endoscopic treatment modalities.
