Micronized purified flavonidic fraction compared favorably with rubber band ligation and fiber alone in the management of bleeding hemorrhoids

Randomized controlled trial


PURPOSE: The aim of this study was to assess the role of micronized purified flavonidic fraction in the management of bleeding nonprolapsed hemorrhoids. METHODS: Patients were randomly assigned to receive ispaghula husk alone, rubber band ligation plus ispaghula husk, or micronized purified flavonidic fraction plus ispaghula husk. Other colorectal diseases were excluded by colonoscopy. Blinded observers noted the time for bleeding to stop completely, recurrences, and treatment complications. RESULTS: A total of 162 patients were randomly assigned with no significant differences in the age and gender distributions among the groups. Hemorrhoidal bleeding was relieved most expediently in the micronized purified flavonidic fraction plus ispaghula husk group (ispaghula husk alone n=66, mean (standard error of the mean) 10.6 (2.3) days; rubber band ligation plus ispaghula husk n=57, 5.6 (1.1) days; micronized purified flavonidic fraction plus ispaghula husk (n=39, 3.9 (1.2) days;P=0.03). However, there were no significant differences in the recurrences at six months of follow-up (ispaghula husk alone n=8 (12 percent); rubber band ligation plus ispaghula husk n=12 (21 percent); micronized purified flavonidic fraction plus ispaghula husk n=2 (5.1 percent);P=0.075). No complications or side-effects were noted. CONCLUSIONS: micronized purified flavonidic fraction used with fiber supplements rapidly and safely relieved bleeding from nonprolapsed hemorrhoids.
