[Sonographic findings in Crohn's disease].

In 59 subjects (25 men and 34 women) with confirmed Crohn's disease 91 sonographic examinations were made, using dynamic records by means of a sector probe with a frequency of 3.5 and 5 MHz. The disease had persisted on average for 7.1 years. A positive sonographic finding was recorded in 68% of the examined subjects, incl. 42% where the finding on palpation of the abdominal cavity was negative. During examination the following typical findings were recorded: the symptom of a tubular structure with a thickened intestinal wall (frequency 77.5%), cockade symptom (65%), convolution of the loops (62.5%), congestion in the intestinal loops (10%) and abscess in the abdominal cavity (7.5%). Ultrasonography is a significant diagnostic method which can help in the differential diagnosis of resistance on palpation and in the follow up of the disease and the effect of therapy in patients with Crohn's disease.

[Ultrasonic findings in pancreas divisum].

In 36 subjects with pancreas divisum an ultrasonic examinations of the pancreas were made after filling the stomach with 600 ml of fluid. In 27 subjects (75%) it was possible to evaluate the entire pancreas reliably, incl. the area of the dorsal segment. The gastric filling and positioning of the patients during examination improved in 47% the quality of the visualization, in particular in the left half of the pancreas. In three patients sonography revealed marked inflammatory changes in the entire gland. The applied examination procedure protracted the examination time of the pancreas to 30-40 minutes. Aimed ultrasonic examination with gastric filling is recommended as part of the examination procedure in subjects with pancreas divisum.

[I.V. administration of Mendiaxon in ultrasonography of the gallbladder and bile ducts].

Group of 48 patients was ultrasongraphically examined for suspicion of a pathological process in the gallbladder and bile passages region. Because of inadequate depicting spamocholeretic agent Mendiaxon was administered. In slow i. v. administration no side effects were observed. Improvement of the gallbladder picture was scored in 51.4%, bile passages in 50% of investigations. Mendiaxon administered during the examination itself represents possibility how to influence successfully ultrasonographic diagnostics.

[Ultrasonic diagnosis of abdominal diseases (author's transl)].

Ultrasonic examination is a modern method used to visualize intraabdominalorgans and pathological processes affecting their organisation. This method of examination is safe and gentle as regards the patient and suitable for estimation of extraluminar pathological conditions. The report concerns experiences gained with abdominal ultrasonography effected with Echoview VI Picker (Transducer 2,25 MHz, diameter 13 mm) at the department of internal medicine of the University Policlinic in Prague in 1975--1977. There was a total of 400 examinations of the abdominal cavity effected in 358 subjects. The principal indications for examination included a clinical finding or suspicion of a disease affecting the pancreas (180X), liver (79X), spleen (30X), gall-bladder (24X), kidney (21X), or undefined palpation findings in the abdomen (74X). In 41,75% of cases sonography confirmed the abdominal finding, in 44,75% of cases the finding was not confirmed, in 13,5% of cases the finding could not be estimated dependably. As the frequency of positive findings achieved by ultrasonic examination in pancreatic pseudocysts is high, we effect sonography in the instance of suspection of this affection prior to the planned endoscopic retrograde cholangiopancreaticography as orientation examination.
