“…It results showed a higher sensitivity and specificity of color Doppler ultrasound, suggesting that this study is part of the initial assessment of any neonate with clinical features sugges- tive of necrotizing enterocolitis. It was found that the absence of flow in the intestinal wall, suggesting ischemia, and increased vascularization of the same, indicating an inflammatory process incipient, are aspects that facilitate the clinical management early [24].…”

Purpose: To disseminate the current knowledge about the intestinal inflammatory processes in children and its approach by ultrasound (US) and provide necessary information to pediatricians for early diagnosis through this complementary method. Source of Data: The sources of data were selected by Medline, the international manuscripts, international medical journals more relevant in the last 20 years about Gray Scale and Color Doppler Ultrasound in the evaluation of inflammatory bowel disease in children and adolescents. Conclusions: Several authors have suggested that the ultrasound should be the first study in the diagnostic investigation process in suspected inflammatory bowel disease to determine the most affected region and monitor the therapy response. While colonoscopy still remains as the reference diagnostic method, the literature suggests that US can be an extremely useful tool in the context of the suspected diagnosis of a wide variety of intestinal inflammatory processes in children.

“…Color Doppler U/S may be useful in determining bowel viability, which can be characterized by bowel wall thickness and perfusion. 13,14 Determining the viability by differentiating ischemic from necrotic bowel is not possible using the current radiographic method. Color Doppler detection of absent blood flow showed 100% sensitivity, which is far greater than that of radiographic detection of peritoneal free air (40%) as a positive sign for severe NEC with necrotic bowel (P ¼ 0.3).…”

“…Color Doppler detection of absent blood flow showed 100% sensitivity, which is far greater than that of radiographic detection of peritoneal free air (40%) as a positive sign for severe NEC with necrotic bowel (P ¼ 0.3). 14 In NEC, inflammation causes initial hyperemia in the bowel wall, which is followed by ischemia and bowel wall thinning. This progression of NEC, which was confirmed by color Doppler U/S evidence, 13 is illustrated in Figure 3.…”

“…Bowel ultrasonography provides an opportunity for the evaluation of bowel dynamics as well as free intra-abdominal fluid. Many studies have emphasized the higher diagnostic accuracy of gray-scale and Doppler ultrasonography over plain abdominal radiography for the detection of some bowel wall changes, especially those in bowel wall thickness, echogenicity, and perfusion, as well as portal venous gas and focal or free intra-abdominal fluid [7][8][9][10][11][12][13][14].…”

Objective To evaluate the role of Doppler ultrasonography in the assessment of splanchnic circulation's hemodynamic changes in septic preterms at risk of necrotizing enterocolitis. Methods A total of 51 septic preterms were divided into two groups: 25 preterms with clinical signs of necrotizing enterocolitis (NEC) and 26 preterms with no clinical signs of NEC. Both groups were assessed with Doppler ultrasonography of the celiac and superior mesenteric arteries, and each septic preterm's peak systolic velocity (PSV), end-diastolic velocity (EDV), resistivity index (RI), and pulsatility index (PI) was calculated and recorded. Results These included a statistically significant lower PSV (p: 0.001) and a lower EDV (p: 0.001) in the superior mesenteric artery in the septic group with clinical signs of NEC in comparison with the septic group with no clinical signs of NEC. A statistically significant (p \ 0.001) higher PSV celiac (CA)/PSV superior mesenteric (SMA) ratio was found for the group of septic preterms with clinical signs of NEC when compared to the other group. Conclusion The study results showed that Doppler ultrasonography of the splanchnic circulation can be a tool for the early identification of NEC cases among septic preterms.Keywords Doppler ultrasonography Á Splanchnic circulation Á Sepsis Á Preterms Á NEC Sommario Obiettivo valutare il ruolo del Doppler nella valutazione dei cambiamenti emodinamici del circolo splancnico in pz pretermine settiche e a rischio di enterocolite necrotizzante. Metodi 51 pazienti pretermine settiche divise in due gruppi sia con segni clinici di enterocolite necrotizzante (NEC) o asintomatiche, entrambi valutati con Doppler a ultrasuoni delle arterie celiaca e mesenterica superiore, con velocità di picco sistolico (PSV), fine della velocità diastolica (EDV), indice di resistività (RI), indice di pulsatilità (PI) il calcolo e la registrazione. Risultati il più basso PSV è risultato statisticamente significativo (p: 0.001), il valore inferiore di EDV (p: 0.001) campionati a livello dell'arteria mesenterica superiore nel gruppo settico con segni clinici di NEC, a confronto con il gruppo delle settiche senza segni clinici di NEC. Statisticamente significativa (p \ 0.001) l'aumento del rapporto PSV celiaco (CA)/PSV a livello della mesenterica superiore (SMA) nel gruppo di sepsi con segni clinici di NEC in confronto con l'altro gruppo. Conclusione I risultati dello studio hanno mostrato che il Doppler del circolo splancnico può essere uno strumento di identificazione precoce dei casi NEC tra le pazienti pretermine settiche.
