Abstract
Hemorrhoids are local vascular structure dilations in the lower rectum, associated with morbidity and reduced quality of life. Endovascular coil or particle embolization of the superior rectal arteries, known as Emborrhoid technique, is a minimally invasive, image-guided therapy that targets the hemorrhoidal plexus and reduces hemorrhage. The purpose of this review was to analyze the results of published studies to determine the efficacy, clinical outcomes, and morbidities associated with the endovascular occlusion of hemorrhoidal arteries for the treatment of internal hemorrhoids. Current evidences suggest that hemorrhoids treated by Emborrhoid technique using microcoils, embolic particles or a combination is safe with no reported serious complications. Hemorrhoid embolization can preserve the anal tone without direct anorectal trauma and maintain the hemorrhoidal tissue in place requiring minimal local wound care on an outpatient basis. However, due to the paucity of high-quality trials, further research is warranted to evaluate its long-term outcomes, compare its efficacy with other treatment modalities, and fully assess its role in the treatment of hemorrhoid.
