Abstract
Background. The surgical approach in chronic anal fissures (CAF) may, occasionally result in anal incontinence. The aim of this investigation was to study feasibility, effectiveness, and safety of hydropneumatic anal dilation (HAD) in conservative treatment of CAF and to compare it with local nitroglycerin (GTN) treatment. Methods. Efficacy of HAD was evaluated in 109 patients (65 male, 44 female; mean age, 53.3 years), following anal dilation using Microvasive Rigiflex instrument (Otw 40 mm). Thereafter, 36 patients were randomly divided into two groups to undergo treatment with 0.25% GTN or HAD. Results. Recovery rate with HAD was 79.8% after 10 days and 94.5% after 30 days. An immediate (within 24 hours) drop was observed in the level of pain; no significant complications or recurrence were reported within 2 years. Healing rate was 94.5% following HAD vs. 38.9% after GTN. Conclusion. HAD should be considered a new safe option in CAF treatment. [ABSTRACT FROM AUTHOR]
