| 目的 探讨螺旋CT在先天性肛门直肠畸形(CARM)术前诊断及指导临床治疗的价值。 方法 30例CARM患儿于术前接受X线倒立侧位腹部平片和盆腔螺旋CT检查,分别测量直肠盲端到肛窝距离,分析两种检查方法的测量结果与手术结果的相关性;并结合CT三维重建图像判断骶骨有无畸形。 结果 CT测量直肠盲端到肛窝距离与术中测量结果呈正相关(r=0.99,P<0.01);诊断骶尾椎弯曲1例。X线平片与手术测量结果无相关性(r=0.31,P>0.05)。 结论 螺旋CT检查在术前可准确描述CARM直肠盲端的位置及骶骨发育情况,为临床选择最佳术式及判断预后提供可靠的依据。 |

| Objective To investigate the value of spiral CT for the diagnosis and treatment of congenital anorectal malformations (CARM). Methods Thirty children with CARM underwent lateral upside-down plain film in abdomen and spiral CT scanning in pelvic cavity before surgical operation. The distance between rectal blind end and anal fossa in two imaging modalities was measured. The correlation between the measurement results in two imaging modalities was compared with operational results. Sacral deformation was diagnosed according to 3D reconstruction of CT images. Results The measurement results obtained from CT were correlated positively with those of operation (r=0.99, P<0.01). CARM combined with curved sacrum was diagnosed in one child. No correlation was found between the measurement results of X-ray and operation (r=0.31, P>0.05). Conclusion Spiral CT scanning can accurately describe the atresic level of rectum and malformation of sacrum. It can provide reliable evidence for surgeon to choose the best surgical method and to judge prognosis. |
