To identify magnetic resonance imaging (MRI) features associated with colorectal surgical bowel resection for treatment of deep infiltrating endometriosis (DIE).
122 preoperative pelvic MRIs in women with laparoscopically-proven DIE and subsequent surgery (2006-2015) were identified, and retrospective cohort analysis performed. MRIs were reviewed independently by two radiologists blinded to surgical/histopathological outcomes. Associations between MRI characteristics of middle/posterior compartment endometriosis and surgical outcomes were investigated to identify MRI features associated with colorectal surgical bowel resection.
MRI features associated with colorectal surgical intervention were: presence of an MRI bowel lesion (sensitivity 95.3%, specificity 63.3%, ROC-AUC 0.79); MRI bowel lesions ≥20 mm in length (sensitivity 91%, specificity 77%, ROC-AUC 0.84); MRI bowel lesions invading the muscularis or submucosa/mucosa layers (sensitivity 95.3%, specificity 63.3%, ROC-AUC 0.90).
This study identifies MRI features that have potential diagnostic utility in identifying the need for colorectal surgical intervention in patients with DIE.
确定与结直肠手术切除治疗深部浸润性子宫内膜异位症（DIE）相关的磁共振成像（MRI）特征。
回顾性分析 2006 年至 2015 年间经腹腔镜证实患有 DIE 并随后接受手术治疗的 122 例女性患者的术前盆腔 MRI 资料。由两位对手术/组织病理学结果不知情的放射科医生对 MRI 进行独立评估。研究 DIE 中后盆腔子宫内膜异位症的 MRI 特征与手术结果之间的相关性，以确定与结直肠手术切除相关的 MRI 特征。
与结直肠手术干预相关的 MRI 特征包括：存在 MRI 肠病变（敏感度 95.3%，特异度 63.3%，ROC-AUC 0.79）；MRI 肠病变长度≥20mm（敏感度 91%，特异度 77%，ROC-AUC 0.84）；MRI 肠病变侵犯肌层或黏膜下层/黏膜层（敏感度 95.3%，特异度 63.3%，ROC-AUC 0.90）。
本研究确定了 MRI 特征，这些特征可能有助于诊断 DIE 患者是否需要结直肠手术干预。
