目的 探讨高频超声对小儿梅克尔憩室所致肠梗阻的诊断价值。方法 选取广州市妇女儿童医疗中心2018年1月—2023年12月经手术证实的由梅克尔憩室引起的肠梗阻患儿41例作为研究对象,回顾性分析患儿临床资料及超声表现,并与术中所见和病理结果进行对照。结果 41例患儿,发病平均年龄为（3.97±3.69）岁,其中男32例、女9例。术前超声诊断肠梗阻38例,诊断符合率为92.7%;诊断梅克尔憩室所致肠梗阻9例,诊断符合率为21.9%。术中诊断梅克尔憩室索带卡压肠管24例,腹内疝8例,肠扭转1例;肠套叠10例;梅克尔憩室炎症、粘连6例,粘连穿孔1例;憩室内异物并穿孔1例。结论 高频超声对小儿肠梗阻有重要的诊断价值,仔细探查可以明显提高梅克尔憩室所致肠梗阻的临床诊断率,为临床尽早手术提供重要依据。

Objective To investigate the diagnostic value of high frequency ultrasound for intestinal obstruction caused by Meckel's diverticulum in children．Methods From January 2018 to December 2023,41 children with intestinal obstruction caused by Meckel's diverticulum were selected as the study objects．The clinical data and ultrasound images of the children were analyzed retrospectively,and compared with the intraoperative and pathological results．Results In 41 patients,the average age of onset was（3.97±3.69）years ,including 32 males and 9 females．Preoperative ultrasonic diagnosis of intestinal obstruction in 38 cases,diagnosis coincidence rate was 92.7%．Intestinal obstruction caused by Meckel's diverticulum was diagnosed in 9 cases,the diagnosis coincidence rate was 21.9%．During the operation,24 cases of Meckel's diverticulum intestinal compression were diagnosed,8 cases of abdominal hernia,1 case of intestinal torsion,and intussusception of 10 cases．Meckel's diverticulum had inflammation and adhesion in 6 cases and adhesion perforation in 1 case．A case of foreign body in diverticulum with perforation．Conclusions High-frequency ultrasound has an important diagnostic value for intestinal obstruction in children．Careful exploration can significantly improve the clinical diagnosis rate of intestinal obstruction caused by Meckel's diverticulum,and provide an important basis for early clinical operation．

目的 进一步提高宫腔粘连的超声诊断准确率。方法 对476例超声诊断的宫腔粘连病例进行回顾性分析。结果 476例经阴道彩超诊断的宫腔粘连患者,超声主要表现:内膜回声连续性中断,内膜厚薄不均。超声结合临床表现,将患者分成轻度粘连、中度粘连和重度粘连。71例重度粘连患者于我院行宫腔镜治疗。经阴道彩超结合临床,对宫腔粘连的诊断准确率达100%。结论 经阴道彩色多普勒超声是诊断宫腔粘连首选的检查手段。经阴道彩超结合临床,对宫腔粘连具有很大的诊断价值,对粘连的分级有助于指导临床制定治疗计划。

Objective To improve the ultrasound diagnostic accuracy rate of Intrauterine Adhesions. Methods Retrospectively analysis of 476 intrauterine adhesions cases were diagnosed by the transvaginal color ultrasound. Results Main imaging characteristics of 476 IUA cases were endometrial echo interruption, uneven thickness, et al. Combining ultrasound with clinical performance, the data was classified into three types: mild IUA, moderate IUA, severe IUA. 71 cases of severe IUA were treated with hysteroscopy surgery. Conclusion Transvaginal ultrasound with clinical data diagnosis for the intrauterine adhesions has higher practical value. The classification is helpful for making the treatment plan.
