在手术中准确诊断子宫内膜异位症非常重要。尤其对一些不易查到的和微细病灶,因为它影响对本病的研究和治疗。本文阐述一种帮助术者识别微细病灶的简单技术。在腹腔镜诊断子宫内膜异位症时常可见到血性腹腔液,这些血性腹腔液可以是经血逆流、腹腔内出血、腹腔镜套管针穿刺或手术操作的结果。血液的理化特性使其与腹膜表面微小的物理变异相互作用,可使流动着的红细胞勾划出不规则的表面,由此 Accurate diagnosis of endometriosis in surgery is very important. Especially for some difficult to find and fine lesions, because it affects the research and treatment of the disease. This article describes a simple technique that helps the operator identify fine lesions. In laparoscopic diagnosis of endometriosis often see bloody peritoneal fluid, these bloody peritoneal fluid can be menstrual flow, intraperitoneal hemorrhage, laparoscopic trocar puncture or surgical results. The physico-chemical properties of blood interact with small physical variations in the peritoneal surface, allowing the flowing erythrocytes to profile irregular surfaces,
