Sigmoidovaginal fistula (SVF) is an extremely distressing and complex condition that significantly impacts a patient's quality of life. The successful management of SVF relies on accurately identifying the fistula's location and tract. However, preoperative localization can be challenging in certain cases. In this report, we describe a rare complication in a patient with stage IVA cervical cancer who developed SVF after concurrent chemoradiotherapy. Conventional diagnostic methods, including electron colonoscopy, methylene blue testing, and fistulography, were unable to locate the fistula. As an alternative, we used a non-contact hysteroscopic technique, which successfully identified the location, size, and number of fistulas. This method is particularly effective for patients with SVF, especially in postmenopausal women with narrowed or adherent vaginal tracts, women with intact hymen, and those with complex, high-grade vaginal fistulas resulting from cancer treatment with chemoradiotherapy.
乙状结肠阴道瘘（SVF）是一种极其痛苦且复杂的病症，会严重影响患者的生活质量。SVF的成功治疗依赖于准确识别瘘管的位置和通道。然而，在某些情况下，术前定位可能具有挑战性。在本报告中，我们描述了一名IV A期宫颈癌患者在同步放化疗后发生SVF的罕见并发症。包括电子结肠镜检查、亚甲蓝试验和瘘管造影在内的传统诊断方法均无法确定瘘管位置。作为一种替代方法，我们使用了非接触式宫腔镜技术，该技术成功识别了瘘管的位置、大小和数量。这种方法对SVF患者特别有效，尤其是绝经后阴道狭窄或粘连的女性、处女膜完整的女性，以及因放化疗癌症治疗导致复杂、高级别阴道瘘的患者。
