The Two Treatment Methods Compared the Sclerosing Agent Injection and the Rubber Wrapping

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

5. Internal hemorrhoids were combined with complications such as chimerism, thrombosis, ulceration, or infection;
6. Poor basic conditions can not tolerate endoscopic treatment, such as serious cardiovascular and cerebrovascular diseases, respiratory dysfunction, liver and kidney failure, mental disorders, etc.;
7. There are other serious diseases involving the rectum and anus, such as anal fistula, perianal infection, anal stenosis, inflammatory bowel disease activity period, colorectal tumors, etc.;
8. Patients with severe coagulation dysfunction or long-term oral anticoagulant drugs or antiplatelet aggregation drugs without withdrawal;
