Comparative capacities of radiation studies in the diagnosis of circumscribed peritonitis in case of duodenal microperforation at different stages of emergency medical care

: The results of ultrasound (US) and X-ray studies were retrospectively studied in the diagnosis of circumscribed peritonitis in case of microperforation from duodenal ulcers at different stages of emergency medical care. Analysis of the findings has demonstrated that on admission and in its first hours the most effective diagnostic method is plain radiography that enables free gas accumulation to be found under the diaphragm and US study is of low informative value. Repeat targeted US study using expert-class scanners, with the well stated task based on clinical laboratory findings, is a high-informative diagnostic technique for circumscribed peritonitis in case of duodenal perforations.
