指标中文名:

通过梨状窝时间

指标类型:

主要指标

Outcome:

The pyriform sinus passage time

Type:

Primary indicator

测量时间点:

进镜时

测量方法:

使用电子秒表测量,起点为内镜头端抵近喉咽部、即将进入目标梨状窝的瞬间(以监视器图像中内镜抵达会厌水平并开始转向目标侧梨状窝为准),终点为内镜明确通过食管上括约肌、镜身进入食管上段(通常距门齿约20-25厘米)并可自由推送的瞬间(以食管腔清晰、稳定显像为准)。

Measure time point of outcome:

During insertion

Measure method:

Measurement was performed using an electronic stopwatch. The starting point was defined as the moment when the tip of the endoscope approached the laryngopharynx and was about to enter the target pyriform sinus (determined by the monitor image showing the endoscope reaching the level of the epiglottis and beginning to turn toward the target pyriform sinus). The endpoint was defined as the moment when the endoscope clearly passed the upper esophageal sphincter, with the shaft entering the upper e
