Background

As foreign body ingestion/food impaction is one of the less common indications for upper endoscopy in adults, few studies have investigated outcomes. We aimed to determine the distribution of ingested items warranting endoscopy and to identify factors associated with successful endoscopic retrieval.

Methods

We conducted a retrospective, cross-sectional study, identifying all endoscopies performed between June 2006 and June 2018 for foreign body ingestion or food impaction. We performed univariate and multivariate analyses to identify variables associated with endoscopic foreign body visualization and successful removal from the mouth.

Results

Of the 168 endoscopies identified, the ingested item was visualized in 131 (78%) and was removed from the mouth in 88 (52.4%). 6.5% of cases required surgery and 2.4% of cases had a perforation noted. The two most common foreign bodies were food boluses (51.2%) and bones (28.6%). Older patients were more likely to have their ingested foreign body visualized during endoscopy (age ≥ 70 compared to 18–29 adjusted odds ratio [aOR] 8.78; 95% CI 1.62–47.70) and more likely to have it removed from the mouth (aOR 5.57; 95% CI 1.34–22.85). Bones were less likely to be visualized on endoscopy (aOR 0.16; 95% CI 0.04–0.57) but not less likely to be removed successfully (aOR 0.85; 95% CI 0.42–1.72). Foreign bodies visible on radiography were more likely to be identified on endoscopy (aOR 9.07; 95% CI 2.71–30.37) and more likely to be successfully removed (aOR 2.82; 95% CI 1.26–6.32).

Conclusions

Factors such as age, radiographic visibility, and the suspected foreign body may affect the likelihood that it can be visualized and removed. Future studies should focus on further characterizing complications of foreign body ingestions and the types of patients and objects most at risk.

异物摄入内窥镜检查结果的预测因素：一项横断面研究。

背景

由于异物摄入/食物嵌塞是成人上消化道内镜检查不太常见的适应症之一，因此很少有研究调查结果。我们旨在确定需要内镜检查的摄入物品的分布情况，并确定与成功内镜检索相关的因素。

方法

我们进行了一项回顾性横断面研究，确定了 2006 年 6 月至 2018 年 6 月期间对异物摄入或食物嵌塞进行的所有内镜检查。我们进行了单变量和多变量分析，以确定与内窥镜下异物可视化和成功从口腔中取出相关的变量。

结果

在确定的 168 例内窥镜检查中，131 例 (78%) 可以看到摄入的物品，88 例 (52.4%) 将其从口腔中取出。6.5% 的病例需要手术，2.4% 的病例有穿孔。两种最常见的异物是食物丸（51.2%）和骨头（28.6%）。老年患者更有可能在内窥镜检查期间看到他们摄入的异物（年龄 ≥ 70 与 18-29 调整优势比 [aOR] 8.78；95% CI 1.62-47.70）并且更有可能将其从口腔中取出（aOR 5.57；95% CI 1.34–22.85）。内窥镜检查不太可能看到骨骼（aOR 0.16；95% CI 0.04–0.57），但成功移除骨骼的可能性却不小（aOR 0.85；95% CI 0.42–1.72）。X 光片上可见的异物更可能在内窥镜检查中发现（aOR 9.07；95% CI 2.71-30。

结论

年龄、射线照相可见度和可疑异物等因素可能会影响其被可视化和移除的可能性。未来的研究应侧重于进一步表征异物摄入的并发症以及最危险的患者和物体的类型。
