下消化道子宫内膜异位症病灶左侧分布率高 意大利Vercellini P等回顾近20年文献,探讨回盲部与结肠子宫内膜异位症病灶的分布特点。共检索出68篇文献,合计337例病例。结肠子宫内膜异位症位于右侧84例,左侧245例,双侧8例。仅分析单侧子宫内膜异位症患者,左侧发生率(74％,245／329;95％CI:69％-79％)显著高于平均几率(50％,P=0.0001)。证实下消化道子宫内膜异位症的侧别分布与卵巢(63％)、宫骶韧带(65％)、输尿管(64％)的分布情况类似,且左侧分布率(74％)更高。这一结果支持了经血逆流学说,提示异位病变来源于子宫内膜,反流内膜细胞受解剖与力学因素影响分布种植(BJOG,2004,111:1213-1217)。多症状联合诊断子宫内膜异位症的阳性预测值高 有研究者前瞻性评估了重度痛经与子宫直肠窝
Lower left upper gastrointestinal endometriosis lesions distribution rate Italy Vercellini P review of nearly 20 years of literature to explore the distribution characteristics of ileocecal and colon endometriosis lesions. A total of 68 articles were retrieved, totaling 337 cases. Colonic endometriosis located in the right side of the 84 cases, 245 cases left, bilateral in 8 cases. On analysis of unilateral endometriosis, the incidence of left (74%, 245/329; 95% CI: 69% -79%) was significantly higher than the mean (50%, P = 0.0001). Confirmed that the side distribution of lower gastrointestinal endometriosis and ovarian (63%), uterosacral ligament (65%), ureteral (64%) of the distribution of the situation, and the left distribution rate (74%) higher . This result supports the theory of menstrual blood flow, suggesting that ectopic lesions originate from the endometrium, and that endodermal cells are affected by anatomical and mechanical factors (BJOG, 2004, 111: 1213-1217). Multiple symptoms combined diagnosis of high predictive value of endometriosis Researchers have prospectively evaluated the severe dysmenorrhea and uterine rectal fossa
