The study aimed to explore the risk factors of infections after enterostomy through the information data analysis method based on a mathematical model.
156 cases of enterostomy patients admitted to the hospital were retrospectively selected as the study subjects and were divided into the infection group (17 cases) and normal group (139 cases) according to whether they were complicated with infections. Then, the factors of infection and related indexes before and after surgery were analyzed, and the data of the whole hospital were estimated by mathematical modelling.
The length of hospital stay in the infection group was 21 ± 11.2 days, which is longer than 10.1 ± 7.1 days in the normal group ( < 0.05). The incidence of anastomotic fistula in the infection group was 14%, which is higher than 2% in the normal group. The mortality rate of infection group (44%) was higher than that of normal group (5%). In the infection group, the incidence of single-cavity stoma (69%) was higher than that of double-cavity stoma (31%), the nosocomial infection rate (11%) was significantly higher compared with out of hospital (2%), and there were significant differences ( < 0.05).
Patients with malnutrition and hypoproteinemia before enterostomy, the use of gastric tube and ventilator in the treatment, single lumen stomy in the operation, and the occurrence of anastomotic fistula were more likely to have concurrent infections.
本研究旨在通过基于数学模型的信息数据分析方法，探讨肠造口术后感染的危险因素。
回顾性选择 156 例住院肠造口患者为研究对象，根据是否合并感染分为感染组（17 例）和正常组（139 例）。分析手术前后感染的因素及相关指标，并通过数学建模对全院数据进行估计。
感染组的住院时间为 21±11.2 天，长于正常组的 10.1±7.1 天（ < 0.05）。感染组吻合口瘘的发生率为 14%，高于正常组的 2%。感染组的死亡率（44%）高于正常组（5%）。感染组单腔造口（69%）的发生率高于双腔造口（31%），院内感染率（11%）明显高于院外（2%），差异有统计学意义（ < 0.05）。
肠造口术前存在营养不良、低蛋白血症、治疗中使用胃管和呼吸机、手术中单腔造口以及吻合口瘘的发生，更容易并发感染。
