常规腹部超声检查,对结肠疾病的诊断仅处于极次要的地位。为确定结肠逆行液体灌注是否能改善超声检查对大肠肿瘤的诊断价值,作者对220例待行结肠镜检查的病人进行了前瞻性研究。这些病人平均年龄为52岁,超声检查前24小时,服用3×10g 硫酸镁,或检查当日清晨用轻泻剂灌肠。肌注 20mgN-丁基溴化东茛菪碱后,向结肠内灌入1500ml 水,随即用实时超声仪对大肠进行连续经腹超声检查。
Routine abdominal ultrasound examinations are only of secondary importance for the diagnosis of colon diseases. To determine whether retrograde perfusion of the colon can improve the diagnostic value of ultrasonography for colorectal tumors, the authors performed a prospective study of 220 patients undergoing colonoscopy. The average age of these patients was 52 years old, 24 hours before the ultrasound examination, taking 3 x 10g magnesium sulfate, or checking the morning with a laxative enema. After intramuscular injection of 20 mg of N-butyl scopolamine bromide, 1500 ml of water was poured into the colon, and the large intestine was continuously subjected to transabdominal ultrasonography with a real-time ultrasound apparatus.
