直到目前,儿童和青春期上消化道出血的诊断和治疗并不满意。因为有1/3～1/2的病例不能确定其出血来源。过去由于上消化道X线检查是唯一的诊断方法,所以才出现这种情况。自从1970年在儿科开展应用内窥镜和腹部选择性血管造影以来,已显著地改善了我们对胃肠道出血病因的诊断和治疗能力。 Until now, children and adolescent upper gastrointestinal bleeding diagnosis and treatment are not satisfied. Because 1/3 to 1/2 of the cases can not determine the source of bleeding. This happened in the past because the upper gastrointestinal X-ray examination was the only diagnostic method. Since applying endoscopy and abdominal selective angiography in pediatrics in 1970, we have significantly improved our ability to diagnose and treat gastrointestinal bleeding.
