Partial or complete obstruction was diagnosed by means of sonography with water filling (hydrosonography) in 48 patients with rectal or colonic cancer. The procedure appeared highly effective in detecting pathological lesions larger than 1.0 cm. It may be useful under urgent surgical conditions as a method of choice in diagnosing the nature of lesion, size, endophytic growth or grade of invasion. Hydrosonography using retrograde contrast filling may considerably enhance the potential of standard and transabdominal scanning.

The results of ultrasound study were analyzed in 148 and 26 patients with acute small and intestinal obstruction, respectively, the causes of the latter included different diseases of the intestine and abdominal organs. The commonest ultrasound symptoms based on the diameter of the bowel, on the thickness and structure of the intestinal wall, on the status of mucosal motility folds of intestinal loops and on the pattern of motility were defined. They enable one to differentiate large and small intestinal obstruction and to define its degree with a high degree of validity. Abdominal ultrasonography used in the emergency surgical setting may rapidly solve problem in the diagnosis of abnormal changes, differential mechanical and functional ileus in most cases. Dynamic ultrasound monitoring allows the efficiency of the treatment performed to be evaluated.
