本文观察口服一定量米粉后呼出气中 H_2含量,即米粉呼吸氢试验,以间接了解来吸收的碳水化合物量。评价其对可疑吸收不良患者的诊断价值。实验对象分4组:健康对照组(A组)23例;胰腺疾病组(B组)17例,均经剖腹术或内窥镜逆行胰胆管造影术证实;小肠疾病组(C 组)22例,均用传统的对比放射检查术或/和粘膜活检确诊,其他疾病对照组(D 组)10例,为非吸收不良性腹泻者,其中溃疡性结肠炎6例,肠道激惹综合征4例。受试者实验前2周起停用抗生素及特殊治疗。晚餐后禁食,次晨于30分钟内进食完100g 米粉试验餐,
This paper observed a certain amount of oral administration of rice after exhaled H_2 content, that is, rice breath hydrogen test to indirectly understand the amount of carbohydrates absorbed. Evaluate its diagnostic value of patients with suspected malabsorption. The experimental group was divided into 4 groups: 23 cases in the healthy control group (group A), 17 cases in the pancreatic disease group (group B), confirmed by laparotomy or endoscopic retrograde cholangiopancreatography; 22 cases in the small intestine disease group (group C) , Were diagnosed by conventional contrast radiography or / and mucosal biopsy, other disease control group (D group) 10 cases of non-malabsorption diarrhea, including ulcerative colitis in 6 cases, irritable bowel syndrome 4 example. Subjects stopped using antibiotics and special treatment 2 weeks before the experiment. Fasting after dinner, the next morning after eating 100g rice test meal within 30 minutes,
