Abstract:Objective To investigate the epidemiological characteristics of gastrointestinal foreign bodies in Zhangzhou, Fujian Province from 2011 to 2020 and analyze the changes of influencing factors of complications.Methods 838 patients with gastrointestinal foreign bodies from 2011 to 2020 were retrospectively analyzed. The patients were divided into the observation group (2016 to 2020, n = 409) and the control group (2011 to 2015, n = 429) according to different visit times. The epidemiological characteristics of the two groups were analyzed, and the influencing factors of complications were analyzed by univariate analysis and Logistic multivariate analysis.Results The type, shape, length and complication rate of foreign body in the observation group were higher than those in the control group (P < 0.05). Logistic multivariate analysis showed that the location of foreign body (OR^ = 2.425, 95%CI: 1.436 ~ 4.674, P = 0.000), length of foreign body (OR^ = 2.314, 95%CI: 1.562 ~ 4.845, P = 0.000), foreign body shape (OR^ = 4.753, 95%CI: 2.325 ~ 8.536, P = 0.000), existence time (OR^ = 3.944, 95%CI: 2.154 ~ 7.332, P = 0.000), foreign body type (OR^ = 2.523, 95%CI: 1.673 ~ 6.503, P = 0.000) were independent influencing factors for complications in patients with digestive tract foreign bodies from 2016 to 2020. Length of foreign body (OR^ = 3.754, 95%CI: 1.864~8.646, P = 0.000), foreign body shape (OR^ = 2.656, 95%CI: 1.235 ~ 6.364, P = 0.000), existence time (OR^ = 2.463, 95%CI: 1.573 ~ 5.255, P = 0.000) were independent influencing factors for complications in patients with digestive tract foreign bodies from 2011 to 2015.Conclusion The epidemiological characteristics of foreign bodies in digestive tract have changed significantly in recent years, mainly reflected in the type, shape and length of foreign bodies. The incidence of complications has also increased. Foreign body location, length, shape, existence time and type are independent influencing factors of gastrointestinal foreign body complications in recent years.
