Corrosive ingestion managements in children

The Impact of Caustic Ingestion on Nutritional Status: Case Report

Introduction

Caustic injuries remain a major public health concern. Nutritional status plays a pivotal role in determining the outcome. Unfortunately, nutritional care guidelines are not widely implemented in clinical practice, and decisions are often based on prior experience and local policies.

Case Presentation

We present the case of an 83-year-old man who accidentally ingested alkali, resulting in severe caustic injury and subsequent complications that further deteriorated his nutritional status. The management of esophageal strictures necessitated constant adjustments to the nutritional strategies employed. The clinical evaluation revealed protein and energy malnutrition, accompanied by type 2 intestinal failure. However, with individually tailored parenteral nutritional therapy, a significant improvement in the patient's nutritional status was observed.

Conclusion

Recognizing that caustic injuries increase metabolic demands, a comprehensive and active nutritional assessment is crucial, focusing on the need for adequate energy, high protein intake, and an appropriate feeding route. In cases of acute or prolonged type 2 intestinal failure with insufficient oral or enteral nutrition, parenteral feeding should be the primary therapy. Effective management of caustic injuries requires a multidisciplinary and multicenter approach, integrating nutritional evaluation, including body composition measurements, into the clinical algorithm. Early initiation of nutritional therapy is vital to prevent chronic intestinal failure.

Outcomes of pneumatic dilation in pediatric caustic esophageal strictures: a descriptive and analytic study from a developing country

OBJECTIVES

Corrosive substance ingestion in children represents a significant public health issue due to its long-term health sequelae. Esophageal stricture, main complication of this dangerous condition, is treated by pneumatic dilation and eventually by esophageal replacement. We aimed, through this study, to report the outcomes of esophageal pneumatic dilation complicating corrosive substance ingestion in children in a developing country.

METHODS

This cross-sectional study was performed on the population of pediatric patients with caustic esophageal stenosis between January 2005 and December 2020. All patients underwent pneumatic balloon dilation. A logistic regression model was built to predict the probability of the occurrence of the event (success/failure) of the dilation. The ROC curve is used to evaluate the performance of the logistic regression model to discriminate between positive and negative values of the dependent variable.

RESULTS

The success rate of pneumatic balloon dilation was 80.4%. The median duration of overall management was 11 months. The severity of caustic stricture observed during endoscopy was significantly linked to worse outcomes (p = 0.001). Multivariate analysis indicated that the severity of stenosis and the number of dilation sessions were independent risk factors for failure of dilation. ROC curve analysis showed that the area under the curve was 71.7%. A Cut-Off point value of 7 provided the best sensitivity and specificity.

CONCLUSION

Pneumatic balloon dilation has been proven to be efficacious in infants with caustic esophageal stricture. Pediatric surgeons should take into account factors to promptly switch to replacement surgery and avoid unnecessary and time-consuming serial dilations.

Procedural and Surgical Interventions for Esophageal Stricture Secondary to Caustic Ingestion in Children

BACKGROUND

Esophageal injury after caustic ingestion can vary in severity and may result in significant long-term morbidity due to stricture development. The optimal management remains unknown. We aim to determine the incidence of esophageal stricture due to caustic ingestion and quantify current procedural and operative management strategies.

METHODS

The Pediatric Health Information System (PHIS) was utilized to identify patients 0-18 years old who experienced caustic ingestion from January 2007-September 2015 and developed subsequent esophageal stricture until December 2021. Post-injury procedural and operative management was identified utilizing ICD-9/10 procedure codes for esophagogastroduodenoscopy (EGD), esophageal dilation, gastrostomy tube placement, fundoplication, tracheostomy, and major esophageal surgery.

RESULTS

1,588 patients from 40 hospitals experienced caustic ingestion of which 56.6% were male, 32.5% non-Hispanic White, and the median age at time of injury was 2.2 years (IQR: 1.4,4.8). Median length of initial admission was 1.0 day (IQR: 1.0, 3.0). 171/1,588 (10.8%) developed esophageal stricture. Among those who developed stricture, 144 (84.2%) underwent at least 1 additional EGD, 138 (80.7%) underwent dilation, 70 (40.9%) underwent gastrostomy tube, 6 (3.5%) underwent fundoplication, 10 (5.8%) underwent tracheostomy, and 40 (23.4%) underwent major esophageal surgery. Patients underwent a median of 9 dilations (IQR 3, 20). Major surgery was performed at a median of 208 (IQR: 74, 480) days after caustic ingestion.

CONCLUSION

Many patients with esophageal stricture after caustic ingestion will require multiple procedural interventions and potentially major surgery. These patients may benefit from early multi-disciplinary care coordination and the development of a best-practice treatment algorithm.

New therapies for esophageal strictures in children

PURPOSE OF REVIEW

The present review aims at describing recent advances in therapeutic strategies for the treatment of benign esophageal strictures in children. We discuss current knowledge and practice on esophageal dilations, which are still the mainstream of treatment. We present new evidence about adjuvant treatments for recurrent and refractory strictures, including endoscopic incisional therapy, esophageal stenting, intralesional or topical mytomicin C and intralesional, systemic or topical steroids.

RECENT FINDINGS

Current evidence on esophageal dilations is not sufficient to establish superiority of one of the available techniques, especially the use of balloon or bougie dilators, but a prospective international cohort study on anastomotic stricture in esophageal atresia is underway to address this issue. Recurrent and refractory strictures still represent a challenge, since none of the adjuvant pharmacological and mechanical interventions has shown to be enough feasible, effective and safe to revolutionize clinical practice.

SUMMARY

In the last couple of years, several encouraging results have been published on management of esophageal strictures in children. Further research is needed, hopefully directed toward secure, easily reproducible and minimally invasive measures.

The Effect of the COVID-19 on Corrosive Ingestion in Thailand

Purpose

Since January 2020, the outbreak of COVID-19 coronavirus has impacted global mental health, daily activities, and economies, including Thailand. The essential strategy is the disease-preventing measure of “lockdown.” Corrosive ingestion is one of the most common forms of self-harm and problems worldwide. This study aimed to evaluate the effect of corrosive ingestion in the COVID-19 situation.

Methods

This was a retrospective study of adult patients (≥18y) who had ingested corrosives and been admitted to surgical department, Thammasat University Hospital between June and December 2019 (pre-COVID-19) and January to June 2020 (COVID-19 period) and compared the epidemiological and clinical features between these two groups.

Results

Nine and 20 patients were admitted in the pre-COVID-19 and COVID-19 periods, for an increase of 122%; males numbered 15. A minority of ingestions, 8/29, were intentional of which 7 were in the COVID-19 period. The Zargar classification showed a trend towards more gastric injury in the COVID-19 vs pre-COVID-19 periods: 8/17 vs 1/9 (p=0.09). Because of the endoscopic grade 0 in stomach was significantly higher in pre-COVID-19 than COVID-19 case (pre-COVID-19; 8 patients (88.9%), COVID-19; 9 patients (45%); p value 0.011).

Conclusion

Data from this study suggest increasing trends of corrosive ingestion and greater gastric injury during the COVID-19 period.
