先天性肛门直肠畸形的术前影像学诊断方法研究进展

Research of Progress in Preoperative Imaging Diagnosis of Congenital Anorectal Malformations

先天性肛门直肠畸形(anorectal malformations, ARMs)是新生儿最常见的消化道畸形,其可合并心脏、泌尿系统及脊柱脊髓畸形等多系统异常。直肠末端位置及伴发瘘管情况是ARMs术前影像学评估的关键。近年来,ARMs的术前影像学检查方法取得重要进展,已从仅评估直肠盲端高度发展到提供包括伴发瘘管情况、肛周肌肉发育及合并其它系统畸形等在内的全面信息,现就不同影像学方法在ARMs术前评估的应用价值及研究进展予以综述。

Congenital anorectal malformations (ARMs) are the most common gastrointestinal malformations in newborns, which can be combined with multiple system abnormalities, such as heart, urinary system and spinal cord malformations. The position of distal rectum pouch and the condition of as-sociated fistula are the key of the preoperative imaging evaluation of ARMs. In recent years, the preoperative imaging examination methods of ARMs have made important progress. It has devel-oped from only evaluating the height of the distal rectum pouch to providing comprehensive infor-mation including concomitant fistula, perianal muscle development and combined systematic mal-formations. This paper reviews the application value and research progress of different imaging methods in the preoperative evaluation of ARMs.
