Clinical Analysis of the Effectiveness of Endoscopic Hemorrhoidal Sclerotherapy

Abstract

The method of injection hemorrhoidal sclerotherapy via rigid anoscope has not been generally accepted because it is difficult to inject a sufficient amount of sclerosant into the adequate site of the rectal mucosa, and because the effectiveness of this method is unsatisfactory. The first paper of the endoscopic hemorrhoidal sclerotherapy was published in 1991, where the new method was shown to overcome the shortcomings of the former method. Since Jan. of 1995 to Oct. of 1998, we performed endoscopic hemorrhoidal sclerotherapy for 187 patients, of which we were able to follow the 166 cases. The purpose of this study is to analyze the clinical effectiveness of the endoscopic hemorrhoidal sclerotherapy. In 63 cases of anal prolapse, the procedure was effective in 58 cases (92.1%) . In 99 cases of hemorrhoidal bleeding it was effective in 98 cases (99.0%) . All 4 cases of anal pain were effective. Retreatment was needed in 22 cases. And surgical therapy was needed in 6 cases. By using this technique we were able to select the adequate site for injection and were able to inject the sclerosant sufficiently and safely. In conclusion, the endoscopic hemorrhoidal sclerotherapy is an easily-perfomed, safe, and effective modality for the treatment of symptomatic internal hemorrhoids.
