- 3. Ultrasound Non-invasive Non-iradiating Real time Accessible Relatively cheap imaging technique extremely useful for the diagnosis of abdominal patology Useful aslo for the transabdominal evaluation of the gastrointestinal tract
- 4. • The transabdominal gastrointestinal ultrasound allows the evaluation of the entire digestive tract • oesophagus (especially the oesogastric junction) • stomach • duodenum • small bowel • appendix and colon.
- 5. • Transabdominal gastrointestinal ultrasound (GIUS) - non-invasive evaluation of the bowel including extra-intestinal features such as the splanchnic vessels, mesentery, omentum and lymph nodes. • Good accuracy and reproducibility not only in a primary work up, but also in the follow up of chronic diseases. • extensive data for the usefulness of GIUS in clinical practice • fully implemented only in some countries • lack of standardization of the examination technique, and of guidelines.

- 6. • The echographic evaluation of the digestive tract is addressed to experienced sonographists who are able to recognize all abdominal and parenchymatous structures. • Several additional techniques • progressive compression of an air-containing organ, • water administration in order to improve the stomach visualization, or • hydrosonography • the use of 3.5 MHz convex and 5-7.5-10 MHz linear probes, and the use of Power Doppler • may help to better visualize the digestive structures.

Ultraschall Med. 2016 Sep 7. • The ingestion of adequate amounts of water improve the assessment of the stomach wall. • The distention of the colonic lumen with instillation of water into the colon, hydrocolonic ultrasound and with oral administration of hyperosmotic solutions allows the visualisation of the colon. • For the small bowel - ingestion of small (250 – 500 ml) amounts of iso- osmolar polyethylene glycol (PEG) solution - US-enterography or Small Intestine Contrast US (SICUS).

- 14. • The sonographic aspect of the GI tract normal wall is represented by 5 layers: • a hyperechoic inner layer – commonly this represents the border between the digestive fluid and the mucosa. • a hypoechoic layer – commonly thin, represents the mucosa, lamina propria, lamina muscularis. • a hyperechoic layer – the submucosa. • a hypoechoic layer – the muscular layer; its thickness depends upon the segment of the digestive tract. • an outer hyperechoic layer – the serous layer, the border to the peridigestive fat.
