目的 自制可排气式人工肛袋并探讨其应用效果。方法 设计可排气式人工肛袋,由底盘和袋体组成,袋体上装有单向排气阀。选取2021年12月—2022年5月在浙江省某三级甲等医院行结直肠癌根治术并且术后留有人工造口的84例患者为应用对象,采用随机数字表法将患者分为试验组42例和对照组42例。试验组采用自制可排气式人工肛袋,对照组采用常规人工肛袋。比较两组在术后排便时间、进食时间、住院天数的差异以及医护人员和患者的满意度,以及两组患者术后肠梗阻的发生率。结果 试验组术后排便时间、进食时间、住院天数均少于对照组,差异具有统计学意义（P<0.05）;试验组对人工肛袋排气的满意度高于对照组,差异具有统计学意义（P<0.001）;试验组术后肠梗阻发生率明显低于对照组（χ²=6.098,P<0.05）。结论 可排气式人工肛袋排气操作方便,节时省力,提高了患者舒适度和满意度,降低了肠梗阻的发生率,同时缩短了平均住院日,更好地落实了快速康复理念。

Objective To make an artificial anal bag and explore its application effect. Methods The artificial anal bag was composed of a chassis and a bag body which was equipped with a one-way exhaust valve. A total of 84 patients with artificial stoma after radical resection of colorectal cancer in a tertiary Grade-A hospital from December 2021 to May 2022 were selected as the application objects. The patients were divided into the experimental group（42 cases）and the control group（42 cases）by random number table method. The experimental group received self-made ventable artificial anal bags,and the control group received conventional artificial anal bag. The differences of postoperative defecation time,feeding time and length of hospital stay between the two groups were compared,as well as the satisfaction of medical staff and patients,the incidence of postoperative ileus between the two groups. Results The postoperative defecation time,feeding time and hospitalization days of experimental group were less than those of control group,the differences were statistically significant（P<0.05）. The satisfaction of experimental group was higher than control group,the difference was statistically significant（P<0.001）. The incidence of postoperative ileus in experimental group was significantly lower than that in control group（χ²=6.098,P<0.05）. Conclusion The ventable artificial anal bag is convenient to operate,time and labor saving,improve the comfort and satisfaction of patients,reduce the incidence of intestinal obstruction,shorten the average length of hospital stay,and better implement the concept of enhanced rehabilitation.
