Twenty-one patients with anorectal anomalies were evaluated with magnetic resonance (MR) imaging. In seven preoperative patients, MR imaging demonstrated the level of atresia correctly by showing the rectal pouch and sphincter muscles. The exact location and development of the sphincter muscles were estimated and associated anomalies involving the kidneys and the spine and its contents were evaluated. In 14 postoperative patients, the location of the pulled-through intestine was examined in relation to the sphincter muscles. MR imaging demonstrated operative complications affecting rectal continence--such as a misplaced neorectum, inadvertently pulled-through mesenteric fat, and an implantation mucous retention cyst--and provided objective data for individuals with persistent incontinence after surgery who were under consideration for repeat surgery. The authors recommend MR imaging in all patients being considered for repeat procedures and in any patient without prior surgery who is suspected of having a high anomaly; any degree of sacral agenesis; or spinal, genito-urinary tract, or cloacal anomalies.
对21例肛门直肠畸形患者进行了磁共振（MR）成像评估。在7例术前患者中，MR成像通过显示直肠盲袋和括约肌正确地显示了闭锁水平。估计了括约肌的确切位置和发育情况，并评估了涉及肾脏、脊柱及其内容物的相关异常。在14例术后患者中，检查了拖出肠管相对于括约肌的位置。MR成像显示了影响直肠控便的手术并发症，如直肠新生物位置不当、无意中拖出的肠系膜脂肪和植入性黏液潴留囊肿，并为考虑再次手术的术后持续性失禁患者提供了客观数据。作者建议，对于所有考虑再次手术的患者以及任何未接受过手术但怀疑有高位畸形、任何程度骶骨发育不全或脊柱、泌尿生殖系统或泄殖腔畸形的患者，均应进行MR成像检查。
