A Multicenter Prospective Clinical Study of Endoscopic Foam Sclerotherapy for Internal Hemorrhoids

Xinhua Hospital, Shanghai Jiao Tong University School of Medicine700 enrolled

Overview

"Internal hemorrhoid" affects the quality of life due to hemorrhage and prolapse as a common and frequently-occurring disease. Endoscopic sclerosing agent injection has replaced traditional surgery and become the most commonly used treatment method in developed countries. At present, how to reduce the side effects of sclerosing agent and accurately determine the injection site and depth has become a difficult clinical problem. The research group creatively put forward the theory of foam sclerosing agent to treat internal hemorrhoids in the early stage. With the aid of transparent cap, the visibility of surgical field of vision can be improved. The mini probe ultrasound (MPS) is proposed to effectively evaluate the submucosal in

Outcomes

Primary Outcomes

the condition of bleeding、perianal pruritus 、the degree of prolapse of internal hemorrhoids and the influence of internal hemorrhoids by self-assessment.

After 12 months,all the participants will receive the telephone follow-up to record their self-assessment.

Time frame: 12 months

the condition of perianal pruritus、the description of hemorrhoids(include the number and depth of hemorrhoids)、the need for additiongal sclerotherapy under colonic endoscopy.

after 12 months ,all the participants will receive the colonic endoscopy and we will record the degree of prolapse of internal hemorrhoids、the numbers of hemorrhoid under colonic endoscopy.

Time frame: 12 months

Secondary Outcomes

the condition of participants' bleeding、perianal pain and perianal pruritus after the endoscopic treatment.

one day after receiving endoscopic treatment , all the participants will receive the telephone follow-up and we will record their self-assessment,include the condition of bleeding、perianal pain and perianal pruritus.

Time frame: 1 day

the condition of bleeding、perianal pruritus 、the degree of prolapse of internal hemorrhoids and the influence of internal hemorrhoids by self-assessment.

After 3 months,all the participants will receive the telephone follow-up to record their self-assessment.

Time frame: 3 months

the condition of participants' bleeding、perianal pain and perianal pruritus after the endoscopic treatment.

one week after receiving endoscopic treatment , all the participants will receive the telephone follow-up and we will record their self-assessment,include the condition of bleeding、perianal pain and perianal pruritus.

Time frame: 1 week

the condition of perianal pruritus、the description of hemorrhoids(include the number and depth of hemorrhoids)、the need for additiongal sclerotherapy under colonic endoscopy.
