Objective To explore optimal proposal and theorical mechanism for treatment of chronic ulcerative colitis(UC) with the therapeutic instrument inducting combined energies into anus.Methods 76 patients with mid-range chronic UC were sampled and divided into two groups randomly.Patients in both groups were all withdrawn from drugs and treated with the therapeutic instrument inducting the combined energies into the anus by choosing different combined energies.There were 41cases in the treated group and they were treated with intracavity electrod synchronizing with electrotherapy,heat therapy,magnetic therapy and massor.35 cases in the control group were treated with intracavity electrod synchronizing with heat therapy and magnet therapy.The two groups were compared after twelve months.Results The general improvement rate and cure rate of the two groups showed great significant difference(P

This article introduces the structure, principle and characteristics of a new anorectal therapeutic apparatus. The adoption of new technologies, new components and new materials lays the foundation for the compatibility for electric energy, magnetic energy and thermal energy as well as the safety and comfortability of the intracavitary electrode. The intracavitary electrode possesses the functions of electrotherapy, thermotherapy, magnetotherapy and massage, and thus can be applied to the physical therapies of colitis, irritable bowel syndrome and prostatitis. The apparatus has such advantages as reliable curative effects, no toxic and side effects, simple manipulations, low cost, etc, and thus should be popularized.
