RESUMEN
Endoscopic hemorrhoidal ligation with a rubber band was carried out on 40 patients with internal hemorrhoids. All the patients were treated in the outpatient ward. Seven patients complained of mild to moderate aches in the early postoperative days, which were easily controlled by medication. One week after the treatment, no patient complained of pain. None of the patients had any postoperative bleeding. The results of this treatment were classified as good (no complaint or symptoms after the treatment), fair (at least some improvement), or poor (no change or worse than before the treatment). Twenty-nine of the 40 patients were classified as good, and the remaining 11 patients were fair. No patients were classified as poor. EHL is a harmless and painless procedure and is easily performed in the outpatient ward. When internal hemorrhoids of operative indication are detected by colonoscopy, EHL can be easily and simultaneously carried out.
