[Usefulness of endosonography in patients with colostomy before decision of decolostomy].
The aim of this study was to visualize the suspected defects of the anal sphincters in patients following colostomy by anal ultrasound (AUS) and to analyze possible factors that could have led to such defects. For AUS, Bruel & Kjaer scanner with 7.0 MHz endorectal probe was used in a group of 30 patients with a colostomy. Anal sphincters defects were qualified and quantified. For statistical analysis the ANOVA (Analysis of Variance) was used. Internal anal sphincter (IAS) was thin in all but three patients (27 patients; 90%) with the mean thickness 1.64 mm. A circular reduction of the thickness was seen in 23 patients (85.18%) and along the entire length of the IAS in 20 patients (74.07%). Echogenicity of the IAS was increased in 18 patients (60%) and in 13 of them (72.22%) this defect embraced the whole length and circumference of the IAS. The margins of the IAS were not well-defined in 11 patients (36.66%). A significant correlation was found between duration of the stomy and the IAS echogenicity defect (p-value = 0.0001). Endosonography of the anal sphincter may play an important role before a decision of decolostomy after Hartmann's operation or closing a loop colostomy.
