  ■ 研究摘要

  背景

  中国南方医科大学南方医院姜泊教授等进行的一项研究表明,单气囊小肠镜(SBE)似乎在诊治可疑小肠疾病方面安全、有效。

  研究近日刊登于《消化病杂志》[J Dig Dis 2012 ,13(12): 609]。

  方法

  该研究从2009年1月至2011年8月,对67例疑似有小肠疾病并接受经口或经肛门SBE检查的患者进行了回顾性分析。

  该研究目的旨在评估三级医疗中心SBE的功效、诊断阳性率和安全性。

  研究数据取自临床和内镜电子病例。研究对SBE的适应证、操作时间、诊断阳性率和并发症进行了总结和评估。

  结果

  结果显示,研究在67例患者中共进行了42次经口SBE检查及38次经肛门SBE检查。患者主要因为不明原因消化道出血(OGIB,40.3%)和腹痛(29.8%)被转诊。

  SBE平均操作持续时间:经口途径操作耗时68.1分钟,经肛门途径操作耗时77.5分钟。估计的小肠镜插入深度为:经口途径(247.6±80.3)cm,经肛门途径(131.1±68.7)cm。

  结论

  总体诊断阳性率为68.7%。在OGIB和不明原因慢性腹痛患者中,诊断阳性率分别为74.1%和50.0%。在研究过程并没有发生具有临床意义的并发症。

  SBE是一种诊治可疑小肠疾病安全、有效的手段。 

  ■ 专家点评

  SBE可提高小肠疾病的诊断阳性率, 但也有缺点

  南方医科大学南方医院 白杨

  南方医院消化内镜中心是国内开展气囊辅助内镜进行胃肠疾病诊治最早的内镜单位之一,包括双气囊小肠镜和SBE。小肠镜的应用使得小肠疾病患者得以及早获得诊断和治疗,并因此明显提高了小肠疾病的诊断阳性率和小肠疾病患者的预后。

  该研究是一项SBE用于可疑小肠疾病患者诊治的研究,其结果表明SBE是一种安全、有效的诊疗手段。总体上,对于可疑的小肠疾病患者,SBE与双气囊小肠镜均具有安全性好、诊断效能高等优势。

  然而,基于国外研究和我们的经验,SBE与双气囊小肠镜的诊断效能相当,但SBE由于只有一个气囊,在插镜过程中有时不易固定于小肠壁,因而致使进镜过程中易发生滑脱现象,并且其进镜深度不如双气囊小肠镜。 



Objective
This study aimed to evaluate the performance, diagnostic yield, and safety of single-balloon enteroscopy (SBE) at a Chinese tertiary-care center.
Methods
A total of 67 patients with suspected small bowel diseases who underwent SBE via the oral and/or anal routes from January 2009 to August 2011 were retrospectively analyzed. Data were extracted from electronic clinical and endoscopy records. The indications, SBE procedure time, diagnostic yield and complications were summarized and evaluated.
Results
A total of 42 SBE procedures through the oral route and 38 via the anal route were performed in these 67 patients. Patients were referred mainly for obscure gastrointestinal bleeding (OGIB) (40.3%) and abdominal pain (29.8%). The mean procedure duration was 68.1 min from the oral cavity and 77.5 min from the anus. The estimated depth of insertion was 247.6 ± 80.3 cm from the oral cavity and 131.1 ± 68.7 cm from the anus. The overall significant diagnostic yield was 68.7%. In patients with OGIB and unexplained chronic abdominal pain, the diagnostic yield was 74.1% and 50.0%, respectively. There were no significant complications.
Conclusion
SBE appears to be a safe and effective method for the diagnosis and treatment of deep small bowel disease.
