“…Intestinal ultrasound uses high-frequency sound waves while using probes with different depths of penetration of abdominal tissues and organs. The received signal image can provide detailed information about the thickness of the intestinal wall, the presence of ulcers or strictures, enlarged mesenteric lymph nodes, as well as the location and extent of inflammation [27]. Colour Doppler is a type of ultrasound that can measure blood flow in real-time.…”

Introduction: Inflammatory bowel disease patients are exposed to frequent procedures and hospital admissions as well as recurrent need for radiological examinations with a high risk of exposure to radiation and contrast.Aim: Our objective was to evaluate the role of a combination of both intestinal ultrasound (IUS) and colour Doppler with different parameters for monitoring changes in inflammation over time and to reveal their potential role in the assessment of response to biologic therapy in inflammatory bowel disease (IBD) patients.Material and methods: Before the induction of biological therapy, IUS together with colour Doppler of the intestine was conducted. Response to therapy was defined following the international guidelines.Results: A total of 45 patients with histopathological diagnosis of IBD were enrolled in the study. All patients received biological therapy and were assessed for response after 3 months. Out of those patients, 34 (75.6%) had good response while 11 (24.4%) failed to respond to the treatment. Our findings point to a strong association between bowel wall thickening (BWT) and serum albumin, erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP). The overall sensitivity of IUS varied from 54 to 93% when evaluating bowel affection, with a specificity of 97-100%, in comparison to our results, which showed a sensitivity of 64-74% and specificity of 79-82%. Doppler parameters could predict the response to the biologic therapy in IBD patients.Conclusions: Intestinal ultrasound and colour Doppler provide a safe, non-invasive way to monitor changes in inflammation and blood flow in the digestive tract.

“…There have been observations of enhanced vascularity in the intestinal walls in severe IBD patients [33]. By taking several measurements of the superior mesenteric artery, such as velocity, RI, or flow volume, many research teams have managed to characterize the disease's activity [27] (Figure 3).…”

“…US grayscale imaging allows for the visualization of wall stratification as a five-layer structure (Figure 6) in the normal intestine [19]. Changes in wall stratification in the submucosal and mucosal layers are not specific for the diagnosis of CD but are commonly used for CD evaluation.…”

“…(1) Distinct presence (Figure 1, Figure 2d,e on TAUS)/indistinct presence (Figure 3, Figure 2b,c on WIUS)/disappearance (Figures 4 and 5) of wall stratification in the submucosal and mucosal layer. As we show in Figure 6, the US image allows for the visualization of the five layers of the bowel: the border between the lumen and mucous layer (hyperechogenic), the mucous layer (hypoechogenic), the submucosa (hyperechogenic), the muscular layer (or the muscle membrane proper) (hypoechogenic), and the serosa layer (hyperechogenic) [19]. We used stratification-related US parameters to observe the border line between the mucosal and submucosal layers because discriminating between these two layers is meaningful for the evaluation of CD.…”

The aim of this study is to clarify whether trans-abdominal ultrasound (TAUS) can reflect actual intestinal conditions in Crohn’s disease (CD) as effectively as water-immersion ultrasound (WIUS) does. This retrospective study enrolled 29 CD patients with 113 intestinal lesions. Five ultrasound (US) parameters (distinct presence/indistinct presence/disappearance of wall stratification in the submucosal and mucosal layers; thickened submucosal layer; irregular mucosal surface; increased fat wrapping around the bowel wall; and fistula signs) that may indicate different states in CD were determined by TAUS and WIUS for the same lesion. Using WIUS as a reference standard, the sensitivity, specificity, and accuracy of TAUS were calculated. The degree of agreement between TAUS and WIUS was evaluated by the kappa coefficient. All US parameters of TAUS had an accuracy >70% (72.6–92.7%). The highest efficacy of TAUS was obtained for fistula signs (sensitivity, specificity, and accuracy values were 63.6%, 96.0%, and 92.7%, respectively). All US parameters between TAUS and WIUS had a definitive (p ≤ 0.001) and moderate-to-substantial consistency (kappa value = 0.446–0.615). The images of TAUS showed substantial similarity to those of WIUS, suggesting that TAUS may function as a substitute to evaluate the actual intestinal conditions of CD.

Background: Paediatric intestinal obstruction is a common surgical emergency and is associated with lots of morbidity and mortality especially in developing countries. Paediatric intestinal obstruction differs from adult intestinal obstruction in terms of aetiology, presentation, management and outcome. This study reports the demography, diagnosis, management and outcome of paediatric intestinal obstruction in pediatric surgical unit of a tertiary hospital in Enugu, Nigeria. Methodology: This was a retrospective study of paediatric patients who presented with intestinal obstruction to the paediatric surgical unit of Enugu State University Teaching Hospital (ESUTH) Enugu, South East Nigeria. Children above one month of age but below 15 years, who presented with symptoms and signs of intestinal obstruction, were recruited for the study. Intestinal obstruction in neonates was excluded from this study. The study period was for one year, from January 1 st 2018 to December 31 st 2018. Result: During the period of the study 45 cases, 30 (66.7%) males and 15 (33.3%) females were managed. The mean age of the patients was 52.2 months. Abdominal pain was the most common presenting symptom and intussusception was the most common cause of intestinal obstruction. Forty two patients (93.3%) did well and were discharged. Two patients (4.4%) died while one patient (2.2%) was discharged against medical advice. Conclusion: Intussusception was the most common cause of intestinal obstruction in the current study. The mortality of 4.4% recorded in this study can be improved upon.
