Contrast-enhanced ultrasound (CEUS) of the gastrointestinal tract provides vascular information helpful for characterizing masses and other pathologies in and around the bowel, similar to contrast applications in other solid organs. However, the use of microbubble contrast agents for the bowel provides additional unique contributions as it gives both subjective and objective information about mural and mesenteric blood flow, invaluable for the determination of disease activity in those many patients affected by inflammatory bowel disease (IBD). IBD is a lifelong chronic disease and has its peak age of onset in adolescence or young adult life. Today, we have moved away from treating patient’s symptoms and strive instead to alter the course of disease by obtaining mucosal healing. Expensive and aggressive biologic therapies and lack of agreement of patient’s symptoms with their disease activity and complications necessitate frequent imaging surveillance, which must be safe, readily available, inexpensive, and effective. Ultrasound with the benefit of contrast enhancement meets these requirements and is shown in meta-analysis to be equivalent to CT and MRI scans for these indications.Electronic supplementary materialThe online version of this article (10.1007/s00261-017-1399-6) contains supplementary material, which is available to authorized users.

“…Kritisch zu bewerten ist eine Studie an lediglich 5 Patienten, in der durch den Einsatz des Kontrastmittels die Erfolgsrate einer kompletten Erfassung von TC, AMS und AMI von 0% auf 100 % gesteigert werden konnte. Eine derart niedrige native Machbarkeit wurde bislang in keiner anderen Publikationen berichtet [76]. Schon 1990 berichte Sabba für die AMS über eine Durchführbarkeit der Dopplermessung von über 50% [77].…”

Ultrasound has gained acceptance in the diagnosis of diseases of the gastrointestinal tract beside the classical methods such as endoscopy and X-ray. In a previous publication we discussed the use of ultrasound in emergency diagnostics (e. g., acute appendicitis, diverticulitis/peridiverticulitis, ileus, invagination and perforation) (part 1). Because of the vast extent of this topic, in this overview we will focus on the current role of ultrasound in the detection and assessment of chronic inflammatory bowel diseases, rare forms of colitis (e. g., bacterial, pseudomembranous and neutropenic colitis as well as intestinal tuberculosis), ischaemic bowel diseases as well as diseases of the upper gastrointestinal tract. In chronic inflammatory bowel diseases, ultrasound can give important additional information such as extension, activity, complication (fistula, abscess, stenosis) and in differential diagnosis. It plays an important role in follow-up investigations and can possibly reduce the number of endoscopic examinations. There is still some debate going on about the significance of colour Doppler ultrasound in assessing the activity and differentiation of stenosis. Furthermore, ultrasound is used as a method to guide interventional therapies for abscesses (puncture and drainage). Colour Doppler ultrasound can diagnose ischaemic bowel diseases and also differentiate these from other aetiologies. Ultrasound plays a greater role in the follow-up and assessment of chronic intestinal ischaemia. In the diagnosis of stomach diseases under favourable conditions ultrasound can show changes of the stomach wall, tumours, ulcers and their complication (perforation, penetration) and disturbances of the motility. But an exclusion is not possible.

SummaryThis study was carried out to determine the effects of short-acting anaesthetics on haemodynamic function determined by Doppler ultrasonography. Prior to anaesthesia, Doppler parameters [peak systolic blood flow velocity (psBFV), end-diastolic blood flow velocity (edBFV), minimum diastolic blood flow velocity (mdBFV) and resistive index (RI)] were obtained from the right common carotid artery (CCA), abdominal aorta (AA) and right kidney in New Zealand rabbits (n=24). Animals were then divided into 3 groups to be anaesthetized with propofol (Group P), 2.5% thiopental sodium (Group T) and xylazine/ketamine HCl (Group XK). During anaesthesia the same Doppler measurements were made. Compared with baseline values, psBFV obtained from CCA increased in Group P (P<0.02) and insignificantly changed in Groups T and XK. psBFV measured from AA in Groups T and XK decreased as compared with baseline values. In the right kidney, psBFV in Group P and edBFV in Group T increased, whereas RI value in Groups T and XK decreased. In conclusion, comparing baseline values, propofol anaesthesia did not significantly alter RI measured from CCA and kidney and blood flow velocities measured from AA. The data suggest that propofol anaesthesia in rabbits results in minimal changes in Doppler parameters.

Anestezi öncesi Yeni Zelanda tavşanlarının (n=24) sağ arteria carotis communis (CCA), aorta abdominalis (AA) ve sağ böbreğinden Doppler parametreleri [en yüksek sistolik kan akım hızı (psBFV), diyastol sonu kan akım hızı (edBFV), en düşük diyastolik kan akım hızı (mdBFV) ve rezistif indeks (RI)] elde edildi. Hayvanlar propofol (Grup P), %2.5 tiyopental sodyum (Grup T) ve ksilazin/ ketamin HCl (Grup XK) ile anestezi altına alınarak, üç grup oluşturuldu. Anestezi sırasında aynı ölçümler tekrarlandı. Bazal değerler ile karşılaştırıldığında CCA'dan elde edilen psBFV Grup P'de yükseldi ve Grup T ve XK'daki değişim önemsizdi. Grup T ve XK'da AA'dan ölçülen psBFV bazal değerler ile kıyaslandığında azaldı. Sağ böbrekte, Grup P'nin psBFV ve Grup T'nin edBFV değerleri artarken, Grup T ve XK'da RI değeri azaldı. Sonuç olarak, propofol anestezisi bazal parametreler ile karşılaştırıldığında, CCA'deki RI, intrarenal RI ve AA'daki kan akımı hızlarını önemli ölçüde değiştirmediği tespit edildi. Veriler propofol anestezisinin tavşanlarda Doppler parametrelerini minimal düzeyde etkilediğini göstermektedir.
