Abstract

Fortyseven consecutive patients with chronic anal fissure and randomly selected 40 patients who had no claims for perianal disease during their life time were included in the study T2weighted sagittal highresolution HR T2weighted and contrastenhanced fatsuppressed T1weighted oblique axial and oblique coronal images were retrospectively analyzed by two observers in consensus Thickness of sphincteric muscles anal canal length anorectal angle thickness of anococcygeal ligament depth of Minor triangle width between subcutaneous sphincters vascularity of posterior commissure visibility of posterosuperior projection of external sphincter and angle between the distal anal canal and posterosuperior projection of external sphincter H angle in patients and in controls were compared and analyzed using t test Mann–Whitney U test and Spearman correlationThe patients with chronic anal fissure had longer anal canal 5150 mm ± 091 vs 4411 mm ± 071 p = 0000 thicker internal anal sphincter muscle at midanal level 418 ± 015 vs 339 ± 007 p = 0007 and wider space between subcutaneous external sphincters 1139 ± 050 vs 689 ± 022 p = 0000 In patients there was a positive correlation between H angle and external sphincter thickness at proximal r = 0347 p = 0021 middle r = 0427 p = 0000 and distal r = 0518 p = 0000 levels of the anal canal
