The aim of the study was to visualize, by anal ultrasound (AUS), the suspected defects of the anal sphincters in the patients after colostomy and to analyze possible factors that could have led to such defects. Patients and methods. AUS, using a 7.0 MHz endorectal probe, was performed in a group of 25 patients with colostomy. The internal anal sphincter (IAS), external anal sphincter (EAS) and puborectalis muscle (PR) were visualized and the defects within them were qualified and quanttfied. For statistical analysis, the analysis of variance (ANOVA) was used. Results. The IAS was thin in all but three patients (22 patients; 88 %) with the mean thickness of 1.62 mm. A circular reduction of the thickness along the entire length of the IAS was seen in 20 patients (90.9 %). The echogenicity of the IAS was increased in 15 patients (60 %), and in 10 of them (66.6 ž), this defect embraced the whole length and circumference of the IAS. The margins of the 1AS were not well-defined in 10 patients (40 %). A significant correlation was found between the length of the patient's life with the stoma and the IAS echogenicity defect (p-value = 0.0001). No significant correlation was found between the dynamic examination, the IAS thickness and the IAS borders definition. Conclusion. The reduced thickness, increased echogenicity and borders definition defect of the IAS are seen in the patients after colostomy.The only significant correlation was confirmed between the length ofthe patient's life with the stoma and the IAS echogenicity defectIzhodišča. Namen raziskave je bil z analnim ultrazvokom (AUS) prikazati spremembe na analnem sfinktru pri bolnikih po kolostomiji. Želeli smo tudi najti in razčleniti vzroke ugotovljenih sprememb. Bolniki in metode. AUS smo izvedli po kolostomiji pri 25 bolnikih in uporabili endorektalno sondo z 7.0 MHz. Okvare notranjega analnega sfinktra smo ovrednotili in za statistično analizo uporabili metodo variance (ANOVA). Rezultati. Notranji analni sfinkterje bil stanjšan pri 22 bolnikih (88 %), srednja debelina pa je bila 1.62 mm. Krožno stanjšanje celotne dolžine je imelo 20 bolnikov (90.9 %). Povečano ehogenost notranjega analnega sfinktra smo ugotovili pri 15 bolnikih (60 %) in pri 10 od njih (66.6 %) je obsegala celotno dolžino in obod sfinktra. Robove notranjega analnega sfinktra ni bilo mogoče dobro določiti pri 10 bolnikih (40 %). Statistično značilno povezavo smo našli med časom trajanja stomije in okvaro ehogenosti notranjega analnega sfinkterja (p = 0.0001). Pri ostalih spremembah pa ni bilo najti statistično značilne povezave. Zaključki. Pri bolnikih po kolostomiji smo ugotovili zmanjšano debelino in povečano ehogenost notranjega analnega sfinktra. Pri nekaterih bolnikih ni bilo mogoče prikazati robov sfinktra. Statistično značilno povezavo smo našli le med časom trajanja stomije in okvaro ehogenosti notranjega analnega sfinktraTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo radiologije in onkologije
