Comparative study between multiple and single rubber band ligation in one session for bleeding internal, hemorrhoids: a prospective study.

ABSTRACT

OBJECTIVE: The aim of this study was to compare the cessation of bleeding and the complications between multiple and single ligation using high ligation technique. MATERIAL AND METHOD: All first-visit patients with bleeding internal hemorrhoids were studied and randomly divided into multiple and single ligation groups. High ligation technique was used. Patients visited the clinic in the second week and were invited to visit the clinic or completed questionnaires after one year. RESULTS: 109 patients were included in the study. 61 patients had multiple ligation and 48 patients had single ligation. The cessation of bleeding in one week occurred in 96.7 per cent of patients in the multiple group and 79 per cent of patients in the single group (p = 0.004). There were no differences between the multiple group and single group concerning postligation pain and tenesmus (6.5% vs 2%, p = 0.532), urinary hesitancy and frequency (6.5% vs 4%, p = 0.904), and rebleeding in one year (27.9% vs 34%, p = 0.710). No major complications such as massive bleeding and pelvic sepsis were noted. CONCLUSIONS: Multiple ligation of bleeding internal hemorrhoids in one session can stop bleeding better than single ligation with no more complications.
