Perineal endometriosis is the presence of endometrial tissue in the perineal region. Early diagnosis and treatment is important due to anal sphincter involvement in almost half of the patients. Endoanal ultrasonography is a reliable technique in the assessment of perineal endometriosis with anal sphincter involvement. This report describes the presentation, clinical investigation, and surgical treatment of a perineal endometriosis case CASE REPORT: 32-year-old female patient presented with cyclic pain and swelling of an old episiotomy scar. Three-dimensional endoanal ultrasonography showed a lesion with involvement of the external anal sphincter muscles, and it was completely excised and primary sphincteroplasty was performed for the external anal sphincter defect.The final pathology result was reported as endometriosis. Postoperative periods were uneventful and anal incontinence was not observed.
Perineal endometriosis is a rare disease and may involve the anal sphincter muscles. Incomplete excision to protect the sphincters is associated with high recurrence, while extensive excision can cause anal sphincter damage that may cause anal incontinence. Endoanal ultrasonography may be necessary in surgical planning. Primary sphincteroplasty with excision may be necessary in cases of perineal endometriosis with external anal sphincter muscle involvement.

会阴子宫内膜异位症是指子宫内膜组织出现在会阴区域。由于近一半的患者存在肛门括约肌受累，早期诊断和治疗很重要。经肛门超声检查是评估伴有肛门括约肌受累的会阴子宫内膜异位症的可靠技术。本报告描述了一例会阴子宫内膜异位症病例的临床表现、临床检查和手术治疗。
一名 32 岁女性患者出现周期性疼痛和陈旧会阴切开瘢痕肿胀。三维经肛门超声显示病变累及肛门外括约肌，对病变进行了完全切除，并对肛门外括约肌缺损进行了一期括约肌成形术。最终的病理结果报告为子宫内膜异位症。术后情况平稳，未观察到肛门失禁。
会阴子宫内膜异位症是一种罕见疾病，可能累及肛门括约肌。为保护括约肌而不完全切除与高复发率相关，而广泛切除可能导致肛门括约肌损伤，从而导致肛门失禁。经肛门超声检查可能对手术计划有必要。对于伴有肛门外括约肌受累的会阴子宫内膜异位症，可能需要行经肛门超声检查并进行一期括约肌成形术。
