Pain scores on 100 mm Visual Analogue Scale, healing of fissure and side effects (headache and flatus incontinence) were noted at 0,2,4,6 and 8 weeks. Evolution to chronic anal fissure and recurrence rates (3 and 6 months) was also noted. Data was entered on SPSS 16.0 and p value was calculated.
Results: Out of 161 patients, 109 patients (56 in group A and 53 in group B) completed the study. Demographical data was comparable in both the groups. Results were statistically significant (p 0.05). Patients experiencing mild and moderate headache were 5 and 3 respectively whereas 10 (17.8%) patients had temporary flatus incontinence in group A.
