目的 设计消化内镜废液积漏袋，以期为减少术中废液污染情况提供有效工具。 方法 2020年设计消化内镜废液积漏袋，采用便利抽样法选取2021年10月至2022年1月某院消化内镜中心行胰胆管造影术 （endoscopic retrograde cholangiopancreatography，ERCP） 操作的80例患者为研究对象，并依据随机数字法将其分为对照组和观察组，每组40例。对照组术中使用一次性PE手套收集阀门口废液，而观察组使用手术废液积漏袋。比较两组单位时间内收集废液量及废液污染情况评分。 结果 对照组与观察组单位时间内收集废液量分别为3.55（3.2,4.3）ml/h和5.5（4.5,5.8）ml/h，差异有统计学意义（P＜0.001）。观察组废液污染评分以0~1分为主，约占92.5%，其废液污染情况明显优于对照组，差异亦有统计学意义（Z=-5.763，P＜0.001）。 结论 手术废液积漏袋的使用可有效收集ERCP中产生的废液，减少术中废液手术室环境污染情况的发生，值得推广应用。

Objective To design a new digestive endoscopy waste-fluid collection bag in Endoscopic Retrograde Cholangiopancreatography(ERCP),and to provide an effective tool for reducing intraoperative waste liquid contamination. Methods The digestive endoscopy waste-fluid collection bag was designed in 2020. Eighty patients who underwent ERCP operation in a Digestive Endoscope Center from October 2021 to January 2022 were selected by convenience sampling method,and were divided into control group and observation group according to random number method,with 40 patients in each group.In the control group,disposable PE gloves were used to collect the valve port waste liquid,while the observation group used the surgical waste-fluid collection bag.The amount of waste liquid collected per unit time and the score of waste liquid staining were compared between the two groups. Results The amount of waste liquid collected per unit time in control group and observation group was 3.55(3.2,4.3) ml/h and 5.5(4.5,5.8) ml/h,respectively,and the difference was statistically significant (P＜0.001).The waste liquid staining score of the observation group was mainly 0-1,accounting for about 92.5%,and the waste liquid staining situation of the observation group was significantly better than that of the control group,the difference was statistically significant(Z=-5.763,P＜0.001). Conclusions The digestive endoscopy waste-fluid collection bag can effectively collect waste fluid generated during ERCP operation and reduce the occurrence the environmental staining of the operating room,which is worthy of popularization and application.
