Edible Oils Attenuate Button Battery-Induced Injury in Porcine Esophageal Segments

Home Therapies to Neutralize Button Battery Injury in a Porcine Esophageal Model

STUDY OBJECTIVE

Button battery ingestion can cause alkaline esophageal injury. There is interest in first-aid household products to neutralize the injury. The objective was to investigate which household products are effective at reducing button battery injury.

METHODS

Two cadaveric porcine experiments were performed. Experiment 1 utilized esophageal mucosal segments. A button battery (3VCR2032) was placed onto the mucosa, and substances (saline control, honey, jam, orange juice, yogurt, milk, and cola) were applied every 10 minutes for 6 applications. Tissue pH was measured every 10 minutes, and macroscopic ulceration size was assessed at 120 minutes. Experiment 2 used an intact esophageal model with a battery inserted into the lumen and jam, honey, and saline irrigation as per experiment 1. Tissue pH, macroscopic and histopathology changes were evaluated at 60, 90 and 120 minutes.

RESULTS

In experiment 1, only honey and jam had a lower mean tissue pH at 120 minutes (8.0 [standard deviation [SD] 0.9, n=12] and 7.1 [SD 1.7, n=12], respectively) compared to saline solution 11.9 (SD 0.6, n=6, P<.0001). Both honey (0.24 cm2, SD 0.17) and jam (0.37 cm2, SD 0.40) had smaller mean areas of ulceration compared to saline solution (3.90 cm2, SD 1.03, P<.0001). In experiment 2, honey and jam had significantly lower mean tissue pH at all timepoints compared to saline solution. Histologic changes were evident at 60 minutes in the saline group, whereas honey and jam exhibited no or minimal changes until 120 minutes.

CONCLUSIONS

Honey and jam were able to neutralize injury caused by a button battery resulting in a smaller area of ulceration. Jam should be further explored as a possible first-aid option as an alternative to honey in suspected button battery ingestion prior to definitive management.

Can We Do Anything Else before Removing a Button Battery from the Esophagus?-Hyaluronic Acid

OBJECTIVE

 This article tests the protective effect of a commercially available mixture of hyaluronic acid, chondroitin sulfate, and poloxamer 407 on the damage caused by the exposure of esophageal mucosa to button batteries in an animal model.

METHODS

 Experimental study. Sixty porcine esophageal samples were distributed in three groups: control (CG), exposure (EG), and exposure-protection (EPG). In EG and EPG, one CR2032 button battery per sample was inserted, both were subdivided into 2-, 4-, 6-, and 24-hour exposure subgroups, with subsequent battery removal. EPG samples were irrigated with the solution 1 hour after battery exposure. Esophageal pH and final voltage of the battery were measured.

RESULTS

 pH in CG remained stable. No significant differences in pH at 1 hour were found between EG and EPG. In EPG, the pH of the mucosa exposed to the anode was lower than in GE at 2 hours (12.44 vs. 11.89, p = 0.203) and 4 hours (13.78 vs. 11.77, p < 0.0001). In the cathode pH was significantly higher in EG at 2 hours (2.5 vs. 4.11, p < 0.0001), 4 hours (2.33 vs. 4.78, p < 0.0001), and 6 hours (2.17 vs. 2.91, p < 0.0001). Significant voltage reduction at 1 hour was found in EG compared to EPG (0.48 vs. 1.08 V, p = 0.004).

CONCLUSION

 Exposure to hyaluronic acid solution buffers the acidification on the side exposed to the cathode and basification on the anode. This effect can be maintained up to 3 to 5 hours, even after stopping its application. Our results suggest that a solution containing hyaluronic acid could be used as an esophageal protector after accidental ingestion of button batteries.

Role of Honey and Acetic Acid in Mitigating the Effects of Button Battery in Esophageal Mucosa: A Cadaveric Animal Model Experimental Study

The objective of our study was to evaluate the role of honey and acetic acid in mitigating the mucosal injury posed by button battery using esophagus specimens from goat cadavers. This was an in vitro experimental cadaveric animal model laboratory study. We used 40 specimens of cadaveric goat esophagus and divided into four groups (A, B, C and D). The first comparison was between group A (specimens with button battery only) and group B (specimens with button battery coated with honey) for the difference in the degree of mucosal injury and change in pH and temperature. The second comparison was between group C (specimens with button battery removed after six hours) and group D (specimens with 5% acetic acid applied following the removal of the battery after six hours) for the difference in the progression of the mucosal injury and change in pH and temperature. The observer was blinded regarding the allocation of the groups. We used Fisher's exact test and independent sample t-test, to evaluate the statistical association. There was a statistically significant reduction in the degree of mucosal injury in specimens applied with button battery coated with honey compared to the specimens applied with button battery only. Similarly, progression of the mucosal injury was halted in specimens with the application of acetic acid following the removal of the button battery. Honey and acetic acid can mitigate the mucosal effects posed by the button battery in cadaveric goat esophageal specimens.

Secondary esophageal perforation rupture of ascending aorta 16 day accidently-swallowing button battery in a young child: A case report of esophagial foreign body and mini review

Introduction and importance

Foreign body ingestions often occur in children between the ages of six months and three years. Swallowing button battery can cause serious complications such as gastrointestinal mucosa tissue necrosis and esophageal perforation. Fatal secondary lesions after foreign body removal are rarely reported.

Case presentation

We reported a case of 18 months old boy who accidently swallowed a button battery (20 mm diameter, 3.2 mm height) which lodged in the esophagus for 3 days before removed by esophagoscope. Secondary esophageal perforation and rupture of ascending aorta resulted in death 13 days after the battery was removed. The autopsy confirmed the rupture and tissue necrosis of the esophagus and ascending aorta.

Clinical discussion

The button battery incarcerated in the second stricture of the esophagus can cause serious complications and death even after removal due to battery-induced tissue erosion. Great attention should be closely paid to early endoscopic reinspection postoperatively and take comprehensive treatment to avoid similar death.

Conclusion

When the incarceration of button batter occurs in the second stricture of esophagus, the possibility of esophageal perforation and the rupture of main artery should be considered. The comprehensive treatment after operation is as important as taking out the foreign bodies.

Electric Insulating Irrigations Mitigates Esophageal Injury Caused by Button Battery Ingestion

OBJECTIVE

Accidental ingestion of button batteries (BB), usually occurred in children and infants, will rapidly erode the esophagus and result in severe complications, even death. It has been recommended that treatment of this emergent accident as soon as possible with drinking of pH-neutralizing viscous solutions such as honey and sucralfate before surgical removal can mitigate the esophageal injury. Recently, we reported that the electric insulating solutions such as edible oils could mitigate tissue damage in BB-exposed esophageal segments. In this study, we compared the protective effect of kitchen oil with honey or sucralfate, the recommended pH-neutralizing beverages, and with their mixture on esophageal injury caused by BB ingestion in pig esophageal segments and in living piglets.

METHODS

Effect of olive oil irrigations was compared to that of honey or sucralfate irrigations in the BB-damaged esophageal segments freshly collected from the local abattoir and in live Bama miniature piglets with the proximal esophagus exposed to BB for 60 min. Also, the effect of olive oil and honey mixture (MOH) irrigations was assessed in live animals. The BB voltage was recorded before insertion and after its removal. Gross and histological analysis of the esophageal injury was performed after BB exposure in segmented fresh esophagus and 7 days after BB exposure in live animals, respectively.

RESULTS

Olive oil irrigations demonstrated better protective effect against BB-induced esophageal damage, compared to honey or sucralfate for BB-induced esophageal damage in vitro. But in vivo study showed that olive oil alone exacerbated esophageal injury because all esophagi irrigated with olive oil perforated. Surprisingly, irrigations with the MOH showed considerable protective effect for BB-induced esophageal damage in live animals, significantly better than irrigations with honey alone. The MOH decreased BB discharge, reduced area of surface injury, attenuated injured depth of esophageal wall thickness, and downed the mucosal injury index in comparison to using honey alone.

CONCLUSION

Irrigations with olive oil alone couldn't prevent the BB discharge and is harmful for BB ingestion before surgical removal. However, mixed with honey, olive oil very effectively prevents the BB discharging and produces better esophageal protection than honey.

Severe tracheobronchial harm due to lithium button battery aspiration: An in vitro study of the pathomechanism and injury pattern

BACKGROUND

Button battery incidents have become a rising medical issue in recent years, especially for infants. The increasing number of these cases can be explained by the expanding use of objects of everyday life and toys. As a result, button batteries in many households are ubiquitous in different states of charge. The extremely long shelf-life and the increasing energy densities of lithium button batteries boost the potential medical complications of accidental swallowing.

OBJECTIVE

The study aimed to analyze the pathophysiology of damage to tracheobronchial structures by button batteries aspiration over time.

METHODS

CR2032 and CR927 lithium button batteries (3.2/3.0 V) were exposed to porcine trachea preparations intraluminal at 37 °C in intervals up to 36 h. Measurements were made of the voltage curve, the discharge current, and the resulting pH values around the electrodes. The effects on tissue were examined using macroscopic time-lapse images and microscopic pictures of sections of the fixed specimens over time.

FINDINGS

The examinations showed a tissue electrolysis reaction directly after the beginning of battery exposure, which led to an immediate coagulation impairment of the respiratory epithelium. Over time, a strongly alkaline environment was established around the batteries. The resulting tissue colliquation caused profound tissue damage beyond the basal membrane of the mucosa, affecting the tracheobronchial cartilage after only 4 h of exposure time. After 12 h, there was significant necrosis of the annular ligaments of the trachea and the peribronchial pulmonary tissue. After completion of the experimental exposure time of 36 h, there was still a sufficient residual voltage on all button batteries of the experiments.

CONCLUSIONS

Besides accidental ingestion, the aspiration of button batteries is a life-threatening situation. The partial or complete acute airway obstruction in the trachea or the bronchi initially is the leading symptom, as with any foreign body aspiration. However, the results of the investigations show that even after a short exposure time, relevant tissue damage can be caused by the electrolysis reaction of the battery. After 12 h, a profound destruction of cartilage, connective tissue, and smooth muscles was observed in vitro, which may cause significant consequential damage in vivo. These findings reveal the need for rapid diagnosis and immediate foreign body removal after any battery ingestion. Moreover, the results show how relevant prevention of these accidents is, and that future safety modifications of these types of battery by the manufacturers would be appropriate.
