Introduction: Ultrasound examination becomes an important part of digestive tract diagnostics. However, conventional abdominal sonography not always enables a precise evaluation of the colon owing to fecal masses and gas remaining in the intestine. Hydrocolonic sonography is a modification of the standard technique that enables imaging of the large intestine and adjacent tissue structures. The aim of study: The aim of the study was to evaluate hydrocolonic sonography as a tool in Crohn disease (CD) diagnosis. Material and methods: In a prospective study 12 patients were included with histopathologically proven CD. After a standard preparing to colon examination patients were given approximately 2 lof 0.9%salinesolution, and then examined by sonography. Special attention was paid to the bowel wall thickness, its stratification, lumen, haustration and peristaltic activity. Hydrocolonic sonography had sensivity of 90.6% vs. barium enema in determination of the extent of lesions. Results: The most common part involved was cecum (100%) and rectum (50%), while ascending colon showed no changes in any patient. Lesions varied from mild, such was loss of stratification in superficial layers of the intestine wall, tosevere, including narrowing of the lumen, loss of the haustration, with presence of fistulas and extraintestinal fluid cisterns. Mean intestinal wall thickness in changed segments was 6.23±1.02 mm compared to 2.85±0.5 mm in healthy ones. Conclusions: Hydrocolonic sonography is a simple, noninvasive method for imaging of the large intestine. Sińce it is sensitive and enables imaging ofthe intestine wali structure, the method can beused, among others, in diagnostics and monitoring of Crohn disease.
