许多放射医生现在对结肠套叠复位偏爱气灌肠而不用钡或水溶性对比剂。为研究其安全性,作者作了小猪气和液体灌肠引起结肠穿孔的对照实验。135只小猪(1个月大,8～10kg重)用液体或气灌肠引起结肠穿孔。气灌肠用或不用Valsava手法产生肠穿孔(各30只),钡灌肠(20％W/V)用或不用Valsava手法产生肠穿孔(各30只)和泛影葡胺Valsava手法(15只)。全部小猪结肠穿孔后经心内注射戊巴比妥钠处死。灌肠前和死后摄腹部X线片。死亡后立
Many radiologists nowadays favor the enema for intussusception of the colon without the use of barium or water-soluble contrast agents. To study its safety, the authors made a controlled experiment of colonic perforation with piglet gas and liquid enema. 135 piglets (1 month old, 8 ~ 10kg weight) with liquid or gas enema caused by colon perforation. Gastrointestinal perforation (n = 30) was performed with and without Valsava, and intestinal perforation (n = 30) and Valsava manipulation (n = 15) with and without Valsava for barium enema (20% w / v). All piglets were sacrificed by intraperitoneal injection of sodium pentobarbital after perforation of the colon. Abdominal X-ray before and after enema. Standing after death
