一例不明原因消化道出血患者的循证治疗

目的针对1例不明原因消化道出血患者,检索当前最佳证据,探讨临床上常见问题,并为患者制定合理的治疗方案,以控制患者症状,降低病死率。方法在充分评估患者的情况后,提出临床问题,从Cochrane图书馆、MEDLINE、EMbase(1990～2010)、SCIE和CNKI中检索有关不明原因消化道出血的诊疗及临床常见问题的随机对照试验和系统评价,检索时间从建库至2010年,对所获证据进行评价,并结合患者和家属意愿制定治疗方案。结果共检索出与不同问题相关的随机对照试验30篇,系统评价/Meta分析5篇。分析证据并结合患者意愿,最终为患者制定了合理的检查和治疗方案。该患者在胶囊内镜中发现小肠Mickel憩室,在外科行腹腔镜下憩室局部切除。通过6个月的随访,证实该方案对患者有满意的疗效。结论采用循证治疗方法,为不明原因消化道出血患者制定合理治疗方案,可有效提高患者治疗效果。

Evidence-Based Treatment for a Patient with Obscure Gastrointestinal Bleeding

Objective To discuss the common clinical problems and make the individualized treatment for a patient with obscure gastrointestinal bleeding by means of evidence-based medicine, so as to ultimately control the symptoms and reduce the mortality. Methods After the clinical problems were put forward, the systematic reviews and randomized controlled trials （RCTs） were collected in The Cochrane Library （online）, MEDLINE, EMBase, SCIE and CNKI databases, from the date of their establishment to 2010. The treatment protocol was made by combining the assessment of evidence with the willingness of both patient and relatives. Results A total of 30 RCTs and 5 systematic reviews were identified. A rational diagnostic and therapeutic plan was made upon a serious evaluation of the data and willingness of patients. The Mickel＇s diverticulum was found through capsule endoscopy, which was then locally excised under laparoscopy. After a 6-month follow-up, the plan proved to be optimal. Conclusion The treatment efficacy in diagnosed obscure gastrointestinal bleeding has been improved by adopting an individualized treatment plan according to evidence-based methods.
