简介：　　摘要：目的：探究经肛型肠梗阻减压导管在急性低位结直肠梗阻手术中的应用价值。方法：随机选取 2017年 10月～ 2019 年 2月在我院治疗的急性低位结直肠梗阻患者 114例，对患者临床资回顾性分析，随机分成观察组和对照组，每组 57例。其中，对照组患者采用常规治方法，观察组患者采用行经肛型肠梗阻减压导管治疗。治疗后，对比两组患者的腹围、引流量及并发症发生率等指标，判断是否存在明显下移。结果：治疗后，观察组腹围与对照组相比，明显小，引流量大于对照组，差异显著（ P<0.05），具有统计学意义。术后，观察组患者并发症发生率显著低于对照组，差异明显（ P<0.05），具有统计学意义。结论：经肛型肠梗阻减压导管能减少患者腹围、引流肠内容物，对后续治疗具有重要意义，且可降低术后并发症发生率。  　　关键词：急性低位结直肠梗阻；肛型肠梗阻减压导管；应用效果  Abstract: Objective: To explore the application value of the decompression catheter in the operation of acute low colorectal obstruction. Methods: 114 patients with acute low colorectal obstruction who were treated in our hospital from October 2017 to February 2019 were randomly selected. The clinical data of the patients were analyzed retrospectively. They were randomly divided into the observation group and the control group with 57 cases in each group. Among them, the patients in the control group were treated with conventional methods, and the patients in the observation group were treated with trans anal intestinal obstruction decompression catheter. After treatment, the abdominal circumference, drainage volume and complication rate of the two groups were compared to determine whether there was significant downward movement. Results: after treatment, the abdominal circumference of the observation group was significantly smaller than that of the control group, and the induced flow was larger than that of the control group, with a significant difference (P < 0.05). After operation, the incidence of complications in the observation group was significantly lower than that in the control group (P < 0.05). Conclusion: the decompression catheter can reduce the peritoneum and the contents of the drainage intestine, which is of great significance for the follow-up treatment and can reduce the incidence of postoperative complications.
