慢性右上腹或上腹疼,结合厌油、腹胀及食后右肩胛部牵涉疼常被考虑为胆道疾病,而影像学检查又无异常发现。对这种病人施行胆囊切除术只有70～75%的治愈率。由于胆囊是个有收缩功能的器官,收缩功能的丧失可导致胆囊疾病的发生。但关于胆囊收缩的性质和计量至今尚无成功的检查方法。本文报告了一种测量胆囊排空的方法即胆囊收缩素增强肝胆扫描并计算排泄分数(EF)来发现隐匿的胆囊疾病。 Chronic right upper quadrant or upper abdominal pain, combined with anorexia, abdominal distension and post-operative right scapular involvement of pain often considered as biliary disease, and imaging findings were normal. Only 75% to 75% of patients have cholecystectomy. Because the gallbladder is a contractile organ, the loss of systolic function can lead to gallbladder disease. However, the nature and measurement of gallbladder contraction so far no successful method of examination. This article reports a method for measuring gallbladder emptying by identifying cholecystokinin-enhanced hepatobiliary scans and calculating excretory fraction (EF) to detect occult gallbladder disease.
