腹部超声检查对新生儿坏死性小肠结肠炎的临床应用价值研究.

Objective: To explore clinical value of abdominal ultrasonography in the diagnosis of neonatal necrotizing enterocolitis (NEC). Methods: A total of 116 patients with NEC in our hospital from January 2009 to December 2016 were selected as the objects of this study. According to the modified Bell-NEC classification criteria,the patients were divided into diagnosis group (n=50) and suspected group(n=66). According to clinical outcome, the patients were divided into operation group (n=37) and medical cure group (n=79). The results of abdominal ultrasound and X-ray examination were compared between the diagnosis group and the suspected group, and he results of abdominal ultrasound and X-ray examination were compared between the operation group and the medical cure group. Results: In the diagnosis group and the suspected group, the detection rate of abdominal ultrasound on abdominal wall gas and portal venous gas were higher than those of X-ray examination (P<0.05). Abdominal ultrasound also revealed bowel slow peristalsis, loss of peristalsis and seroperitoneum. The detection rate of abdominal ultrasound on bowel wall thickening, intestinal dilatation and seroperitoneum in medical cure group were lower than those in operation group (P<0.05). The detection rate of X-ray film on intestinal dilatation in medical cure group was lower than that in operation group (P<0.05). Conclusion: Abdominal ultrasonography can improve the detection rate of NEC, and has a better predictive effect on the clinical outcome of NEC. [ABSTRACT FROM AUTHOR]
