The management of fistula-in-ano has been based on digital examination and operative findings. MR imaging has shown significant limitations to this approach, particularly in the management of recurrent fistula. The most cost-effective approach may be using a combination of endosonography and MR imaging. Preoperative confirmation of fistula complexity facilitates surgery planning of sphincter saving techniques and prevents sepsis being missed, which has been shown to reduce recurrence. Imaging has a significant role to play in this condition to improve patient outcome.
肛瘘的治疗一直基于指诊和手术所见。磁共振成像（MR）已显示出这种方法存在显著局限性，尤其是在复发性肛瘘的治疗中。最具成本效益的方法可能是结合使用腔内超声和MR成像。术前确认肛瘘的复杂性有助于制定保留括约肌技术的手术计划，并防止漏诊败血症，这已被证明可降低复发率。在这种情况下，成像对于改善患者预后具有重要作用。
