目的评价RX系统在内镜逆行胰胆管造影术中的应用价值。方法采用前瞻性随机对照研究的方法,将解放军总医院消化内科2005年11月至2007年4月行内镜逆行胰胆管造影术(ERCP)治疗的213例患者分为使用传统方式组106例,RX系统组107例。分别记录两组中每个病例的导丝脱出情况、器械交换时间和X线暴露时间。结果传统方式组和RX系统组的导丝超选成功率为分别为97.1%和98.1%。但在传统组中,导丝脱出率(%)和器械交换时间(s)明显高于RX系统组[(10.2±2.3)对(2.4±1.2)及(296±74)对(138±39),均P<0.01];X线暴露时间(s)的总体评价结果也是传统方式组长于RX系统组,为(13±6)对(3±2),P<0.05。结论RX系统可增强内镜医生及助手对导丝交换的掌控性,比传统方式明显快速、可靠、安全,使治疗性ERCP相对简便化,提高了治疗效率。
Objective To evaluate the value of RX system in endoscopic retrograde cholangiopancreatography. Methods A prospective randomized controlled study was conducted in 213 patients with endoscopic retrograde cholangiopancreatography (ERCP) treated in Department of Gastroenterology, PLA General Hospital from November 2005 to April 2007. RX system group of 107 cases. The guidewire withdrawal, instrument exchange time and X-ray exposure time were recorded for each case in both groups. Results The success rates of guidewire over-election in the traditional mode group and RX system group were 97.1% and 98.1% respectively. However, the wire withdrawal rate (%) and device exchange time (s) in the conventional group were significantly higher than those in the RX system group (10.2 ± 2.3 vs. 2.4 ± 1.2 vs. 296 ± 74 vs 138 ± 39) , Both P <0.01]. The overall evaluation of X-ray exposure time (s) was also found to be (13 ± 6) vs. (3 ± 2), P <0.05 in the conventional group. Conclusion The RX system can enhance the controllability of endoscopic doctors and assistants in the exchange of guidewires, which is obviously faster, more reliable and safer than the traditional methods, making the therapeutic ERCP relatively simple and improving the treatment efficiency.
