The presence of fluid in the bowel lumen improves the sonographic visualisation of the gastrointestinal tract, thus permitting earlier and more accurate detection of pathological changes. Hydrocolonic sonographic (HS) is amethod of examination the colon after it has been cleaned and filled with water. Patients and methods. We have evaluated the method in a group of 56 patients by comparing its results with the findings of colonoscopy, double-contrast barium enema or surgery. Results. HS had an overall accuracy of 86%, a sensitivity of 81%, a specificity of 92%, a positive predictive value of 91% and a negative predictive value of 82%. Conclusions. The technique is not suitable for examination the rectum, but apart from that it is comparable in usefulness to double-contrast barium enema. The main limitation of HS is that it requires a lot of experience and skill on the partof the sonologist, which affects its acceptability for diagnostic evaluation of the colonIzhodišča. Tekočina v lumnu izboljša preglednost prebavne cevi do te mere, da se patološke spremembe odkrivajo prej in bolj natančno. Diagnostično metodo zaširoko črevo, ki se po predhodnem izčiščenju retrogradno napolni z vodo, imenujemo hidrokolonsonografija (HS). Bolniki in metode. Uspešnost metode smo testirali v skupini 56 bolnikov z primerjavo izvidov HS in kolonoskopije (KS) ali irigografije ali operativnim izvidom. Rezultati. Celokupna točnost je bila86%, senzitivnost 81%, specifičnost 92%, pozitivna napovedna vrednost (PPV) 91% in negativna napovedna vrednost (NPV) 82%. Zaključki. HS je po uspešnosti primerljiva z irigografijo razen za prikaz rektuma. Omejitev preiskave je v tem, da je zahtevna za preiskovalca, kar vpliva na njeno sprejemljivost v diagnostiki širokega črevesaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaOnkološki inštitut Ljubljana
