Abstract
Purpose
Current data on the occurrence of EFBs in relation to different time periods are scant. The purpose of this study was to compare the occurrence, type and location of EFBs in people who presented at our center on weekdays, weekends and holidays.
Patients and Methods
A retrospective analysis of patients (n=1353) received rigid esophagoscopy for foreign body extraction under general anesthesia from January 2018 to 2020 December.
Results
The occurrence of EFB ingestion was significantly higher (p<0.05) on holidays (2.75/day) than on weekdays (0.91/day) and weekends (1.46/day). Patients were much older on holidays, with a mean age of 58.18 ± 17.34 years, than patients on weekdays (54.71 ± 16.71 years) and weekends (55.05 ± 17.36 years).
Conclusion
Our findings demonstrate that EFB ingestion is most likely to occur on weekends and holidays, and elderly patients should be advised to chewing slowly and eating non-nuclear jujube, especially during holidays, to minimize their risk.
Introduction
Esophageal foreign body (EFB) ingestion has become a relatively common clinical problem, estimated at 13 cases per 100,000 peopleCitation1,Citation2 and accounting for approximately 1500 deaths in the USA annually.Citation3 EFBs represent a major challenge for general surgeons, cardiothoracic surgeons, otolaryngologists, anesthesiologists, emergency department physicians, pediatricians and radiologists. The majority of ingested EFBs are benign courses that will naturally pass spontaneously through the gastrointestinal tract without harm; however, up to 20% of the patients require intervention, and approximately 1% of patients require surgery.Citation4 Rigid esophagoscopy under general anesthesia has traditionally been used by otolaryngologists as the first-line treatment.Citation5
Underlying esophageal pathology was part causes of foreign bodies obstruction and food bolus impaction.Citation6–Citation8 Eosinophilic esophagitis was identified in 27–35% of patients aged<50 years who ingested EFBs, and eosinophilic esophagitis has been increasingly recognized as a potential cause of EFB ingestion.Citation9,Citation10 Among patients without a structural etiology, several underlying factors have been reported, and seasonal variation was reported in one study in which the incidence rates of ingestion of EFBs in summer and fall were much higher than those in winter and spring; this may have be due to a coexisting atopic diathesis.Citation11 Higher incidences of EFB ingestions were also observed during national athletic events, during which dietary indiscretions such as excess alcohol ingestion or overeating, often existed.Citation12 Dietary customs are part of cultural identity and vary based on culture, religious beliefs, countries, and dates. As the saying goes, “bread is the staff of life”, and eating a hearty dinner is a popular form of celebration in Chinese culture, which may affect the occurrence of EFBs.
Current data on the occurrence of EFBs in relation to different time periods are scant. The purpose of this study was to compare the occurrence, type and location of EFBs in people who presented at our center on weekday, weekends and holidays. We hypothesized that specific time periods were associated with dietary indiscretions, leading to increased rates of EFB ingestion.
Patients and Methods
Study Population Selection
This retrospective observational study was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University in Beijing, China. This study was conducted in accordance with the Declaration of Helsinki and all study subjects provided written informed consent. In total, the data of 1353 consecutive patients who underwent foreign body extraction between January 2018 and December 2020 were collected from the electronic medical records database. All of the patients underwent emergency surgery with a rigid esophagoscope under general endotracheal anesthesia in the operating room. We set the age restriction at 18 years and older to reduce admission incidence bias and improve homogeneity to a certain extent because most of patients in our center were adult. All patients received otolaryngological local examinations, neck and chest radiographs (including anteroposterior and lateral views), and computed tomography (CT) scans of the neck and chest to assess the presence, location, size, configuration, and number of ingested objects. A flow diagram of the strategy for inclusion in this study is shown in , and some typical images are presented in . . Cases were excluded if no foreign body was found during surgery or cases integral data were missing. Finally 1353 patients were enrolled in this study.

Definitions, Data Collection
An EFB was defined as a foreign body or food that was swallowed into the esophagus accidentally or deliberately and failed to pass naturally or with induced vomited, requiring surgery or endoscopy. Esophageal perforation was defined as penetration through the wall of the esophagus.
Patient data, included age, sex, and date of surgery, (date was divided into weekday, weekend and holiday depending on the statutory holidays in China), type of foreign body (including fish bone, jujube pit, chicken and duck bone, denture, plastic or metal item, shellfish or crab shell, and food bolus); and site of the foreign body (including upper esophagus, defined as within 22 cm of the upper incisor teeth, mid-esophagus defined as 22–30cm from the upper incisor teeth, and lower esophagus, defined as the terminus of the mid-esophagus (30 cm) to the esophagogastric junction, the four narrowing site: 1) behind the cricoid cartilage at the cricopharyngeus muscle, 2) at the point the esophagus crosses in front of the aortic arch,3) at the level of the left main bronchus, and 4) at the point the esophagus passes through the diaphragm). Complications after foreign body extraction, including perforation and infection, were analyzed.
Data Analysis
Means and standard deviations (SDs) were calculated for normally distributed quantitative variables. Medians and interquartile ranges (IQRs) were calculated for quantitative variables with a skewed distribution. Quantitative variables were analyzed using Student’s t test or Wilcoxon rank-sum test when appropriate. Categorical variables were analyzed using percentages and analyzed using the Pearson chi-square test or Fisher’s exact test when appropriate. A p value less than 0.05 denoted statistical significance. All statistical analyses were carried out with the software package R v.3.4.0.
Results
Over a period of 3 years, including 581 weekdays, 393 weekends and 91 holidays, 1353 patients (530 patients on weekdays, 573 patients on weekends and 250 on holidays) underwent emergent esophageal foreign body extraction with rigid esophagoscopy. shows characteristics and outcomes of patients in weekdays, weekends and holidays. The occurrence of EFB ingestion was significantly higher during the holidays (2.75/day) than on weekdays (0.91/day) and weekends (1.46/day), as shown in . Of these patients, 496 (36.66%) were male, and 857 (63.34%) were female. The average age of whole people was 55.57±17.15 years. Patients treated on holidays were much older, with a mean age of 58.18 ± 17.34 years, than patients treated on weekdays (54.71 ± 16.71 years) and weekends (55.05 ± 17.36 years). Among the patients who were older than 55 years, the mean age was 67.20 ± 9.53 years for patients on weekdays, 68.69 ± 9.74 years for patients on weekends, and 69.56 ± 9.27 years for patients on holidays. And the occurrence of EFB during holidays was more than four times during weekdays, as shown in . The age distributions were significantly different among the three groups (p=0.021). Among the three periods, the percentage of females was higher than that of males (61.51% vs 38.49%, 62.65% vs 37.35%, and 68.8% vs 31.2%, respectively,), but no statistical difference was detected between the three periods.

The types of the foreign body were similarly distributes between the three periods (p=0.537). Jujube pit were the most common foreign bodies (44.15% on weekdays, 43.28% on weekends, and 42.4% on holidays), followed by fish bones (30.94% on weekdays, 30.19% on weekends, and 30.4% on holidays) and chicken and duck bones (14.72% on weekdays, 17.8% on weekends, and 19.6% on holidays). The proportions of denture prosthesis and food bolus ingestion were relatively low.
The locations of foreign bodies were not significantly different among weekdays, weekends and holidays (p=0.465). Most foreign bodies were located in the upper esophagus (73.58%, 73.12% and 72.0%, respectively,). The proportions of serious complications, including perforation and infection, were similar among the three groups.
Discussion
EFB ingestion is a common cause of emergency department visits, estimated at more than 1000,000 cases annually in the USA.Citation1,Citation2 The main finding in our retrospective study was a significant increase in the occurrence of acute EFB ingestion that required surgical extraction under general anesthesia on weekends and holidays compared with weekdays. Patients who underwent EFB extraction on holidays and weekends tended to be much older than those who underwent EFB extraction on weekdays. To the author’s knowledge, based on the literature, this is the largest study comparing the occurrence of EFBs during different time periods.
Multifaceted etiologies contributed to esophageal obstruction cased by foreign bodies. Seasonal variation was assessed in a former study, and the highest incidence of acute esophageal obstruction extraction was observed during the summer and fall, which may be due to coexisting atopic diathesis.Citation11 Dietary indiscretions, such as excess alcohol ingestion or overeating, could contribute to a higher incidence of EFBs during national athletic events.Citation12 Over a 3-year period, we found that patients were more likely to experience emergency esophageal foreign body extraction on holidays and weekends than on weekdays. On holidays and weekends, people may consume a large meal since eating is a common form of celebration in traditional Chinese cultural. The relatively high occurrence of EFB extraction on holidays, especially among elderly patients (above 55 years), are noteworthy results; these factors may be associated with worse outcomes than those on weekdays. Moreover, studies have demonstrated substandard outcomes for emergent operative indications during the weekend, known as the weekend effect, due to inferior operative performance and perioperative care.Citation13
Most ingested foreign bodies can pass through the esophagus and gastrointestinal tract without harm, and foreign bodies lodged in the oropharynx and hypopharynx can be removed in the emergency room. Only a very small minority of patients require surgical treatment in the operation room under general anesthesia which might be associated with increased morbidity and even mortality.Citation6,Citation8,Citation14 Current treatment strategies for EFB ingestion seem to vary widely among different hospitals and even among different treatment teams within the same hospital. Surgical intervention with either flexible or rigid esophagoscopy, which has been demonstrated to be equally effective for foreign body removal with no significant differences in overall complications,Citation15,Citation16 should be the first-line treatment among patients at a high risk of morbidity.Citation5,Citation17 In contrast to Qian’s study, in which all patients underwent foreign body extraction with gastrointestinal endoscope,Citation18 patients in a poor condition were generally referred in our center, which is a national tertiary care center that specializes in otolaryngology and received rigid esophagoscopy.
Previous studies have shown a predominance of sharp-pointed objects in adults.Citation6,Citation8,Citation17 Our findings are consistent with these results; jujube pits and fish bones accounted for more than two-thirds of all EFBs in this series. The types of foreign bodies may vary according to dietary habits, cultural characteristics, and social cultural factors in different regions and countries. Meat was reported as the most commonly involved food items in the Western Hemisphere,Citation19 while fish bones comprised the majority of foreign bodies in South China.Citation20 In the present study, jujube pits ranked first, possibly because of the abundance of jujube in northern China. Population aging is a healthcare challenge worldwide, and there is an increasing tendency of dental prosthesis usage, estimated to range from 13 to 29%, in both developed Europe countriesCitation21 and developing countries.Citation22,Citation23 In patients with dental prostheses who underwent EFB extraction under general anesthesia, the burden associated with morbidity and mortality was much greater than that in younger patients.Citation23
In accordance with previous reports,Citation8,Citation24 most of the EFBs in our series were detected in the upper esophageal tract, which includes the narrowest part of the esophagus. The location, type, size, and sharpness of EFBs are considered risk factors for perforation, the most serious complication, potentially causing life-threatening issues such as severe mediastinitis and hemorrhage.Citation7,Citation25 In our study, the overall incidence of perforation was 15.23% (206 patients) over a relatively short time period of 3 years, which was much higher than those in the majority of studies. The reason for this may be that only adults patients were analyzed, and those patients seeking medical care at our center tend to have a serious condition. Although no significant difference was detected among the three groups, the proportion of perforations on holidays was larger than those on weekends and weekdays, which may because that patients on holidays were older and at high risk for complications.
Emergency extraction is usually performed for therapeutic purpose, nevertheless, esophageal obstruction cased by a foreign body can be a warning sign in patients with underlying esophageal disease.Citation26 A study analyzed 13,092 patients in 61 studies and found that 25.7% of patients presenting with EFB ingestion had an underlying esophageal disorder.Citation8 Zhang et alCitation27 also determined that 54% of patients presenting with EFB ingestion had an underlying esophageal disease.
According to our study, public education about chewing slowly and eating non-nuclear jujube should be targeted at elderly individuals to prevent esophageal obstruction. Additionally, medical workers should be fully prepared, especially during holidays and weekends, since more patients at high risk with EFB ingestion are expected to seek treatment.
Our study has several limitations. First, this was a single-center retrospective study, selection bias and referral bias were inevitable, which limit the generalizability of the findings. Prospective, multi-center observational studies based on large population are needed to further validate the result. Second, we focused on only short-term outcomes. Further studies should assess the long-term effects among different periods.
Conclusion
In conclusion, we demonstrated a significant increase in the occurrence of EFB ingestion on holidays and weekends. Elderly patients should be advised to chewing slowly and eating non-nuclear jujube, especially during holidays, to minimize their risk.
