Prospective Multicenter Clinical Study of Flexible Endoscopic Treatment for Grade I-III Internal Hemorrhoids

Patients were randomized assigned to the EIS group, preparing disposable endoscopic injections and sclerosing which were routinely administered with 1% polycinol.The transparent cap was fixed at the front end of the endoscope in inverted or orthofield of view.The stiffening agent or foam stiffer added to Meilan was injected with a disposable injection needle at 4-6 points at the oral end near the dentate line. Each point contained 0.2-1ml, and stopped after the hemorrhoid nucleus changed color. If necessary, a transparent cap was pressed to stop the bleeding to distribute the stiffening agent evenly.

Patients were randomized assigned to the EBL group and were to be prepared before surgery.After the socket is mounted at the inner lens end, the socket is obviously tied at 1-2cm hemorrhoids at the mouth above the dentate line, usually 2-4 rings.With mucosal prolapse, pericyclic multiple dislocation ligation can be performed 2-3cm above the obvious prolapse.
