摘要
Despite its role in disease there is still no definitive method to assess oesophago-gastric junction competence （OGJ）. Traditionally the OGJ has been assessed using manometry with lower oesophageal sphincter pressure as the indicator. More recently this has been shown not to be a very reliable marker of sphincter function and competence against reflux. Disorders such as gastro-oesophageal reflux disease and to a lesser extend achalasia still effects a significant number of patients. This review looks at using a new technique known as impedance planimetry to profile the geometry and pressure in the OGJ during distension of a bag. The data gathered can be reconstructed into a dynamic representation of OGJ action. This has been shown to provide a useful representation of the OGJ and to show changes to the competence of the OGJ in terms of compliance and distensibility as a result of endoluminal therapy.
尽管有它在疾病的角色，仍然没有权威的方法估计 oesophago 胃的连接胜任(OGJ ) 。传统地， OGJ 作为指示物与更低的食道的括约肌压力用测压法被估计了。更最近，这被显示了不对倒流是括约肌功能和胜任的一个很可靠的标记。混乱象胃食道的倒流疾病那样并且到更小的 extend 弛缓不能仍然完成病人的一个重要数字。这评论看使用作为阻抗测面积池知道在一只袋子的扩张期间在 OGJ 介绍几何学和压力的一种新技术。收集的数据能被重建进 OGJ 行动的一个动态代表。这被显示了提供 OGJ 的一个有用代表并且由于 endoluminal 治疗以依从和膨胀性显示出变化到 OGJ 的胜任。
