高频超声在腹型过敏性紫癜与细菌性肠炎鉴别诊断中的应用价值

APPLICATION VALUE OF HIGH FREQUENCY ULTRASOUND IN DIFFERENTIAL DIAGNOSIS OF ABDOMINAL ALLERGIC PURPURA AND BACTERIAL ENTERITIS

目的探讨腹型HSP的诊断方法。方法选择腹型HSP(A组)和细菌性肠炎患者(B组),各40例。彩色多普勒超声观察两组肠壁受累的节段、肠壁的厚度、结构层次、回声情况,并测量病变肠管收缩期PSV及RI。结果A组主要累及小肠,占82.5%;B组主要累及回盲部及结肠,各占40%、45%。两组比较有统计学意义(χ2=36.61,P<0.05)。A组肠壁厚<9mm者占67.5%,≥9mm者占32.5%;B组<9mm者占100%。两组比较有统计学意义(P<0.05)。结论高频超声能从受累肠段、肠壁厚度等方面有效诊断腹型HSP。

Objective To investigate the diagnostic method of abdominal HSP. Methods Abdominal HSP (group A) and bacterial enteritis patients (group B) were selected, 40 cases each. Color Doppler ultrasonography was used to observe the segmentation of the intestinal wall, the thickness of the intestinal wall, the structure level and echo situation, and to measure the PSV and RI of the diseased intestinal tract. Results Group A mainly involved the small intestine, accounting for 82.5%;Group B mainly involved ileocecal and colon, each accounting for 40% and 45%. The two groups were statistically significant(χ 2=36.61, P <0.05). Group A had a wall thickness less than 9 mm accounting for 67.5%, and greater than 9 mm for 32.5%, and the thickness in group B was all less than 9 mm. The two groups were statistically significant ( P <0.05). Conclusion High-frequency ultrasound can effectively diagnose abdominal HSP from the affected intestinal segment and intestinal wall thickness.
