【摘要】 目的 探讨结直肠癌致肠梗阻的诊断和治疗。方法 回顾性分析2003年1月—2008年12月间72例结直肠癌致肠梗阻的外科诊治资料。结果 72例患者中肿瘤位于右半结肠23例,左半结肠29例,直肠16例,回盲部4例。其中63例手术治疗,一期切除吻合46例,Hartmann术7例,单纯造口10例。有9例因肿瘤全身广泛转移等因素自动放弃手术治疗。结论 重视对结直肠癌致肠梗阻的认识、合理选择手术方式、做好围手术期处理是减少并发症、提高疗效的重要措施。
Objective To explore the application effect of " dual-channel teaching” of the rain classroom platform in airway obstruction teaching. Methods A total of 228 nursing undergraduate students in Grade 2015 were selected as the research subjects by the method of cluster random sampling. Class B (n=115) was randomly selected as the control group and Class A (n=113) was selected as the experimental group. Class B adopted the traditional practical teaching mode, and Class A was integrated with the rain classroom platform on this basis. After the end of the course, the learning situation of the experimental group students were understood through the rain classroom background data, the teaching effects of the two groups were evaluated by the students’ theoretical scores and applied case test scores, and the experimental group student’s evaluation of the rain class was understood by questionnaire survey. Results There were 105 nursing students (92.92%) completing pre-school preparation tasks, 103 (91.15%) participating in the class answering, and 113 (100.00%) completing the after-school exercises. The theoretical scores and applied case assessment scores of the experimental group students were 79.44±6.25 and 83.24±3.64, respectively, and those of the control group students were 68.50±7.96 and 70.59±5.51, respectively, the differences between the two groups were statistically significant (P<0.05). In the experimental group, 92 nursing students (81.42%) liked the rain classroom platform teaching. Conclusion The rain classroom platform teaching can bring about the ecological transformation of the open speech in classroom, and comprehensively improve the overall quality and comprehensive ability of students, which is worthy of promotion and application in teaching.
