Endometriosis is characterised by the presence of endometrial glands and stroma outside the uterus. The GI tract is the most common site for extra-pelvic endometriosis, in particular the rectum and sigmoid colon. Using endoscopic ultrasound (EUS), which combines endoscopy with real-time ultrasonography, the wall of the GI tract and adjacent structures can be examined. EUS-guided fine needle aspirates can be also obtained during the procedure. We report a case of rectosigmoid endometriosis which was diagnosed using EUS.
子宫内膜异位症的特征是子宫外存在子宫内膜腺体和间质。胃肠道是盆腔外子宫内膜异位症最常见的部位，尤其是直肠和乙状结肠。内镜超声（EUS）将内镜检查与实时超声检查相结合，可用于检查胃肠道壁及相邻结构。在该检查过程中还可获取EUS引导下的细针穿刺样本。我们报告一例经EUS诊断的直肠乙状结肠子宫内膜异位症病例。
