Comparing Rectal Artery Embolization and Surgery for Treatment of Bleeding Grade 2 and 3 Internal Hemorrhoids

This Phase II study will compare rectal artery embolization with operative hemorrhoidectomy in adults with symptomatic bleeding grade 2 and 3 internal hemorrhoids. Participants will be randomly assigned to receive one of the two treatments. The study will evaluate how each treatment affects quality of life, symptom improvement, bleeding control, recovery time, and treatment-related side effects. The main question this study is trying to answer is whether rectal artery embolization can provide better short-term quality of life compared with surgical hemorrhoidectomy one month after treatment. The study will also examine whether rectal artery embolization allows patients to return to work and normal activities sooner, reduces hemorrhoid-related bleeding, and has a different rate of treatment-related complications compared with surgery. A total of approximately 102 adult participants will be enrolled at a single academic medical center. The results of this study may help determine whether rectal artery embolization is an effective and less invasive alternative to surgical hemorrhoidectomy for the treatment of bleeding grade 2 and 3 internal hemorrhoids.

Endoscopic Injection Sclerotherapy Versus Endoscopic Band Ligation for Grade I-III Internal Hemorrhoids

This study is a prospective, multicentre, and randomized-controlled clinical study.The researchers wanted to explore the optimal treatment regimen for soft hemorrhoid within I-Ⅲ degrees by evaluating and comparing the effectiveness, safety and cost effect ratio of sclerosing injection and rubber lap ligation in patients with different internal hemorrhoid scores
