In this study of 14 patients with anorectal anomalies CT and MRI were employed for preoperative assessment. The use of a pressure enhanced water soluble enema via the colostomy proved to be an extremely efficient method for showing a fistula. MRI studies were enhanced by the use of vaseline oil and in one case this technique was used prior to surgery to provide important information by injecting through a perineal fistula. CT and axial MRI proved to be more valuable than sagittal MRI which is only useful for the length of the atretic segment. The authors consider that a combined approach using pressure enhanced water soluble enema and MRI will provide the most valuable preoperative information to plan a successful operative approach and enable an accurate prognostic evaluation of continence in these difficult and complex patients.
在这项针对14例肛门直肠畸形患者的研究中，采用CT和MRI进行术前评估。经结肠造口使用压力增强水溶性灌肠剂被证明是显示瘘管的一种极其有效的方法。通过使用凡士林油增强了MRI研究，在1例病例中，该技术在手术前通过会阴瘘管注射以提供重要信息。CT和轴向MRI被证明比矢状面MRI更有价值，矢状面MRI仅对闭锁段的长度有用。作者认为，联合使用压力增强水溶性灌肠剂和MRI将提供最有价值的术前信息，以规划成功的手术方法，并能够对这些困难和复杂患者的控便能力进行准确的预后评估。
