Management of esophageal caustic injury

The Esophageal Mucosa: Clues to Underlying Pathology

Esophageal mucosal abnormalities, when accurately recognized, can provide clues to underlying pathology. In this article, we discuss strategies to enhance the detection and assessment of benign esophageal diseases during upper endoscopy by esophagogastroduodenoscopy (EGD). We provide a summary of skills required to perform high-quality EGD procedures from a technical standpoint, as well as a comprehensive description of the endoscopic appearance of the esophagus in health and in benign, organic diseases including eosinophilic esophagitis (EoE), lymphocytic esophagitis and EoE variants, erosive reflux disease, medication-induced esophageal injuries, infectious esophagitis, and other acute and chronic esophageal injuries. Endoscopic classification systems are also described.

Accidental Trisodium Phosphate [Na3PO4] (TSP) Ingestion in a Child

BACKGROUND

It is not uncommon for a child to present to the hospital due to accidental ingestions, and oftentimes they are the result of a child accessing household cleaning or home improvement products. Typically, the upper gastrointestinal tract is the site of initial tissue insult and prognosis of these cases depends on a variety of factors, including the ingested substance, injury extent, and assessments and treatments rendered. Possible post-ingestion complications that make management difficult may include mediastinitis, hemodynamic instability, gastrointestinal perforation, erosion and scarring.

CASE

In this case, a 13-month-old boy accidently swallowed Trisodium phosphate [Na3PO4] (TSP), a common household all-purpose heavy-duty cleaner. After ingestion, the patient presented to the emergency department where a multi-disciplinary team-initiated care. Work-up included regular vital checks, electrolyte profiles, blood profiles and an esophagogastroduodenoscopy. He was eventually discharged and scheduled to return for follow-up with esophagram, without long term consequences.

CONCLUSIONS

Although the ingestion of TSP has occurred before, the literature regarding consumption of this specific detergent is negligible. This case provides evidence regarding the treatment and outcome of a paediatric patient who accidentally swallowed TSP and offers guidance in the management of their care.

Early management of acute caustic ingestion in pediatrics

This review is intended to provide an overview of currently available literature related to caustic ingestion in pediatric patients, including initial management considerations in symptomatic versus asymptomatic children, timing and necessity of endoscopic evaluations, and the use of various therapeutic interventions. Further, this review provides management considerations for children presenting for evaluation following caustic ingestion based on the best available evidence. Additional research is needed to develop conclusive pediatric guidelines that meet GRADE criteria for management of caustic ingestion in children.

A cross-sectional study of poisoning deaths by rubber latex processing acid in Tripura, India

Background

Rubber latex processing acid poisoning is a frequently encountered phenomenon in Tripura. Formic acid is the preferred choice for coagulating rubber latex in rubber sheet manufacturing units. The objective of this study aimed to assess the epidemiological profile of poisoning deaths by rubber processing acid and to record their autopsy findings.

Methods

This was a 2-year prospective cross-sectional study of deaths by rubber processing acid ingestion, which were brought for postmortem examination in two health care institutes of Tripura. Profiles of the cases were noted from hospital records, family members, Inquest and Challan papers from police and autopsy findings. All data were entered in SPSS software version 23.0, and Pearson's correlation was used to correlate the corrosion of stomach and survival time.

Results

Of 42 cases, 30.90% were between the ages of 41 and 50 years, and the majority were rubber tappers (69.01%). Familial disharmony (52.38%) was the most common cause of acid consumption. Close proximity (within 1 km) of the rubber tapping area to the consumption spots was observed (59.52%). Overall, 97.62% of victims had corrosion of the stomach and congestion of internal organs, and the majority (66.67%) died within 24 h of consumption.

Conclusion

This study emphasises the mortality brought on by rubber latex processing formic acid in areas surrounding rubber plantation. The poisoning prevention and control can be strategised in pre-exposure and exposure levels among vulnerable population based upon Information, Education and Communication model.

Early topical mitomycin-C prevents stricture formation in children with caustic ingestion

AIM

Stricture formation is the most common remote complication of caustic ingestion. The aim of this study was evaluation of the efficacy of early topical endoscopic application of mitomycin C (MMC) in prevention of stricture formation after corrosive ingestion in children.

METHODS

We enrolled 78 children with a history of caustic ingestion within 48 h in a prospective, randomised-controlled study. Only 61 children completed the study and were classified into two groups: group A and B. After initial stabilisation, patients in group A (n = 30) received topical application of MMC within the initial 48 h while patients in group B (n = 31) only received conventional management. Follow-up endoscopic dilatation was done every 2 weeks to patients in either group until no need for further dilatation.

RESULTS

The barium study, which was done on the third week, revealed that all the patients (100%) on conservative management (group B) had strictures while only nine patients (30%) in group A had strictures (P < 0.001). The median number of dilatations required for patients in group B was 26 (min. = 23 and max. = 32) while in group A, it was 0 (min. = 0 and max. = 7) (P < 0.001). The success of early MMC application was complete response in 26 patients (86.7%), partial response in 3 patients (10%) and no response in 1 patient (3.3%). On the other side, conventional therapy with endoscopic dilatation achieved complete response in 11 patients (35.5%).

CONCLUSION

Early topical MMC application proved its efficacy and safety in prevention of scar and stricture formation in children following caustic ingestion.

Is EGD Needed in all Patients after Suicidal or Exploratory Caustic Ingestions?

BACKGROUND

Caustic ingestions are relatively uncommon, but remain a significant source of morbidity. Patients with caustic injury often undergo an urgent EGD, although it is not clear if an EGD is routinely needed in an asymptomatic patient. The study has two primary objectives; 1) to determine the utility of routine EGD in asymptomatic suicidal caustic ingestions; 2) to determine if asymptomatic unintentional acidic ingestions can be managed with observation alone, similar to basic ingestions.

METHODS

This retrospective study, which took place at 14 hospitals in three countries evaluated all patients who presented with a caustic ingestion between 2014-2020. The presence of symptoms and esophageal injury, demographic information, pH of ingested substance, reason for the ingestion, and outcome were recorded.

RESULTS

409 patients were identified; 203 (46.9%) were male. The median (IQR) age was 18 (4-31) years; overall range 10 months to 78 years. Suicidal ingestions accounted for 155 (37.9%) of cases. Dysphagia or dysphonia were more likely in those with significant esophageal injury compared to those without (59.3% vs. 12.6% respectively; OR 10.1; 95% CI 4.43-23.1). Among 27 patients with significant esophageal injury, 48% were found in suicidal patients, compared with 51.9% in non-suicidal patients (p = NS). On multivariate regression, there was no difference in the rate of significant esophageal injury among suicidal vs. non suicidal patients (aOR 1.55; p = 0.45, 95% CI 0.45-5.33). Most ingestions involved basic substances (332/409; 81.2%). Unknown or mixed ingestions accounted for 25 (6.11%) of the ingestions. Significant esophageal burns were found in 6/52 (11.5%) of acid ingestions, compared with 21/332 (6.3%) of basic ingestions. Of the 42 cases of acidic ingestions without dysphagia or odynophagia, 2 (4.8%; 0.58-16.1%) had significant esophageal burns, compared with 9 (3.2%; 95% CI 1.4-5.9%) of the 284 basic ingestions; p = 0.64). On multivariate logistic regression, patients with acidic ingestions were not more likely to experience a significant burn (aOR 1.7; p = 0.11, 95% CI 0.9-3.1) compared to those with basic ingestions. No patient with significant esophageal burns was asymptomatic.

CONCLUSION

In this study, there was no statistical differences in the rates of significant burns between acidic and basic caustic ingestions. There were no significant esophageal injuries noted among asymptomatic patients.

A Dreaded Complication of Corrosive Poisoning Leading to Gangrene of the Stomach and Duodenum: A Rare Case

Corrosive poisoning is common in developing countries like India. It is mainly due to accidental consumption in children, whereas suicide is the usual intent in adults. It leads to devastating injuries, to the upper gastrointestinal tract such as necrosis and perforation. The long-term complications include stricture formation and gastric outlet obstruction. Here, we present the case of a 50-year-old male with an alleged history of corrosive acid ingestion. On contrast-enhanced computed tomography (CECT) of the abdomen, there was an absence of wall enhancement of the stomach and the first part of the duodenum, which was suggestive of necrosis or gangrenous changes with signs of impending perforation of the stomach and the first part of the duodenum. The patient was immediately taken up for surgery, and the intraoperative findings were consistent with the imaging findings.

[Results of emergency management of esophageal lesions related to caustic ingestion in children in the emergency department of the General Reference Hospital of Niamey (Niger)]

Introduction

Caustic ingestion in children is a public health problem; it is mainly due to domestic accidents due to improper packaging and storage of caustic products. It is a medical and surgical emergency whose management is multidisciplinary. The lesions caused by the accidental ingestion of caustics can affect the functional and vital prognosis in 10% of cases.

Methodology

A retrospective, descriptive study from January 2020 to December 2022 (2 years), carried out in the emergency department of the General Reference Hospital of Niamey (Niger). The study included patients less than 15 years old admitted for ingesting a caustic product.

Results

Our study included 17 patients. The average age was 5 years, with age extremes of 2 to 11 years. We noted a male predominance with a sex ratio (M/F) of 2.4. Ingestion of caustic products was accidental in all cases. The caustic product was caustic soda in 59%. The average quantity of product ingested was 5 ml (2 ml to 20 ml). The average consultation time was 3 days (3 hours to 15 days). Clinically, dysphagia was the most functional sign, represented by 13 cases, or 76%. Regarding general signs, 3 patients (18%) were admitted with fever; blood pressure was normal in 15 patients (88%); and 2 patients (18%) were admitted in a state of shock. The respiratory rate was normal in 14 patients (82%). Four patients (24%) were admitted in a state of deterioration in the general condition associated with severe malnutrition and dehydration. On physical examination, 2 patients (12%) presented with abdominal defense at the epigastric level. Examination of the ENT sphere revealed benign buccopharyngeal ulcerations in 2 patients (12%). Esogastroduodenal fibroscopy was performed in 4 patients (24%). The caustic lesions observed in the esophagus were: Zargar stage I at 25%, stage Ila at 50%, and stage Illb at 25%. In the stomach, the lesions were Zargar stage I in 75% of cases and stage III in 25% of cases. An injected thoracic-abdominopelvic computed tomography (CT) was performed in 3 patients (18%). It revealed a lack of enhancement of the esophageal wall compatible with esophageal necrosis in one patient. An esophagogastroduodenal transit was performed in 8 patients (47%) admitted more than 72 hours after ingestion of the caustic. They showed esophageal stenoses longer than 3 cm in 3 patients, multiple esophageal stenoses in 2 patients, a single esophageal stenosis in 2 patients, and a single antropyloric stenosis in 1 patient. Therapeutically, all patients benefited from antiemetics to avoid vomiting and proton pump inhibitors. Intravenous antibiotic prophylaxis with third-generation cephalosporin was administered to 12 patients (71%). Corticosteroid therapy based on IV prednisolone at a dose of 1 g/1.73 m2 per day was used to limit or prevent stenoses in 9 patients (53%). Parenteral nutrition was administered to 7 patients (41%). Endoscopic dilations were performed in 2 patients (12%). Emergency surgical treatment was performed in 7 patients (41%): 3 patients underwent transitional feeding gastrostomies; in 3 others, esophagoplasties by colon transplant were performed, and 1 patient was treated by stripping of the esophagus associated with total gastrectomy. The postoperative course was marked by a leak of esocolic anastomosis in one patient for whom conservative treatment was performed with good progress. The average length of hospital stay was 5 days (1-32 days).

Conclusion

Accidental caustic ingestions can have serious consequences. Preventing these accidents relies on raising public awareness of the dangers associated with improper storage of these products.

The endoscopic management of oesophageal strictures

An oesophageal stricture refers to a narrowing of the oesophageal lumen, which may be benign or malignant. The cardinal feature is dysphagia, and this may result from intrinsic oesophageal disease or extrinsic compression. Oesophageal strictures can be further classified as simple or complex depending on stricture length, location, diameter, and underlying aetiology. Many endoscopic options are now available for treating oesophageal strictures including dilatation, injectional therapy, stenting, stricturotomy, and ablation. Self-expanding metal stents have revolutionised the palliation of malignant dysphagia, but oesophageal dilatation with balloon or bougienage remains first-line therapy for most benign strictures. The increase in endoscopic and surgical interventions on the oesophagus has seen more benign refractory oesophageal strictures that are difficult to treat, and often require advanced endoscopic techniques. In this review, we provide a practical overview on the evidence-based management of both benign and malignant oesophageal strictures, including a practical algorithm for managing benign refractory strictures.

The Effects of Ellagic Acid on Experimental Corrosive Esophageal Burn Injury

This study aimed to investigate the antioxidant effect of Ellagic acid (EA) on wound healing in sodium hydroxide (NaOH)-induced corrosive esophageal burn injury. The interaction networks and functional annotations were conducted using Cytoscape software. A total of 24 Wistar albino rats were divided into control, corrosive esophageal burn (CEB) and CEB + EA groups. Burn injury was created by 20% NaOH and 30 mg/kg EA was per oral administered to rats. At the end of the 28-day experimental period, Malondialdehyde (MDA) content was measured. Esophageal tissue samples were processed for histological staining. The EA-target interaction network was revealed to be involved in regulating crucial cellular mechanisms for burn wound healing, with epidermal growth factor (EGF) identified as a central mediator. An increase in animal weight in the CEB + EA group was observed in the EA-treated group after CEB injury. Burn injury increased MDA content, but EA treatment decreased its level after CEB injury. Stenosis index, collagen degeneration, inflammation, fibrosis and necrosis levels were increased after CEB injury. EA treatment improved histopathology in the CEB + EA group compared to the CEB group. The expression of EGF was decreased in the CEB group but upregulated in the EA-treated group, suggesting a potential involvement of EA in cellular processes and tissue regeneration. EA, through its antioxidative and tissue regenerative properties, significantly contributes to alleviating the adverse effects of CEB injury, promoting wound healing.

Role of N-acetylcysteine and vitamin B complex in improving outcomes of corrosive ingestion

Background

Corrosive ingestion remains a worldwide public health problem. To date, there are no specific medications with approved efficacy in reducing gastrointestinal injury progression following corrosive ingestion.

Aim

The current study assessed the efficacy of N-acetylcysteine (NAC) and vitamin B complex as adjuvant therapy in improving the outcome of patients with corrosive ingestion.

Subjects and methods

The study included 92 patients with acute corrosive ingestion admitted to Alexandria Poison Center. Patients were distributed into four equal-sized groups and managed as such; Group I received the standard treatment protocol. The other three groups received IV antioxidants in addition to the standard treatment; Group II received NAC, Group III received vitamin B complex, and Group IV received both NAC and vitamin B complex. To assess occurrence of delayed complications, barium swallow and meal were done 21 days after acute corrosive ingestion, and every patient was followed up for one year.

Results

Start of oral intake was earliest among patients in Group II, and as a result, the need for parenteral nutrition decreased significantly with a subsequent decrease in duration of hospitalization. The highest percentage of patients showing normal findings of barium swallow and meal was among the two groups that received NAC (72.7% in Group II and 77.8% in Group IV). Group IV patients who received NAC and vitamin B complex had no esophageal strictures with improved outcomes.

Conclusion

NAC and vitamin B complex enhanced recovery in the acute stage, in addition to prevention of delayed complications, especially esophageal strictures.

Highlights

Acute corrosive ingestion is associated with high morbidity because of its catastrophic presentation and lifelong complications.This study was conducted on 92 patients admitted to Alexandria Poison Center (APC).IV NAC significantly decreased the time needed for starting oral intake after acute corrosive ingestion and consequently, the need for parenteral nutrition and duration of hospitalization.No patients suffered from esophageal strictures in the group which received both IV NAC and vitamin B complex.Both NAC and vitamin B complex improved the outcome of patients after ingestion of corrosives whether acids or alkalis.

[Endoscopic ultrasonography in diagnosis of chemical esophageal burn and prediction of cicatricial stenosis]

OBJECTIVE

To analyze the role of endoscopic ultrasonography (EUS) in predicting the risk of cicatricial stenosis after chemical esophageal burn.

MATERIAL AND METHODS

A retrospective study included 56 patients with chemical esophageal burn grade III/IV. Primary endoscopy was performed upon admission. To estimate lesion of muscular layer of esophageal wall, we performed EUS using mini-sensor 20 MHz in 3-5 days after injury. To assess severity of chemical esophageal burn, we used the classification proposed by Volkov S.V. (1997) and supplemented by Pesnya-Prasolova E.A. (2006): grade I - catarrhal damage, grade II - erosive, grade III - ulcerative, grade IV - ulcerative-necrotic damage.

RESULTS

To predict the risk of cicatricial esophageal stenosis, we identified 4 grades (a, b, c, d) of damage to muscular layer of esophageal wall considering EUS data. There was no esophageal stenosis in chemical esophageal burn grade III/IVa and acetic essence poisoning with esophageal burn grade IVb. Cicatricial stenosis occurred in 22 (78.6%) out of 28 patients with chemical esophageal burn grade IV (chemical burn grade IVb following alkalis poisoning and in all patients with chemical burn grade IVc/IVd). The risk of cicatricial stenosis was 9.4 times higher after alkalis burn compared to acetic acid burn.

CONCLUSION

EUS in chemical esophageal burn grade IV made it possible to identify additional grades (a, b, c, d) of damage to muscular layer of esophageal wall. This increased the effectiveness of endoscopic diagnostics and assessment of the risk of cicatricial esophageal stenosis.

Social Media Trends, Dry Scooping, and Extensive Esophageal Ulcerations

We describe a case of severe odynophagia and dysphagia caused by dry scooping of multi-ingredient pre-workout powder (MIPS) with diffuse esophageal ulcerations on upper endoscopy. Dry scooping refers to ingesting work out supplements without the recommended doses of solvent. This trend has been the subject of TikTok and other social media sites aimed at enhancing workout performance. While caustic ingestions leading to esophageal ulcers and strictures are well known, dry scooping ingestion of pre-workout powder as an etiology has not been described. Though caffeine may be the predominant content in such powders, the exact composition and ratios of other constituents, including amino acids, are less clear. Complete abstinence from ingestion of the pre-workout formulation and the use of a proton pump inhibitor therapy led to significant clinical and endoscopic recovery over a 4-week period. A thorough history of ingestions, including supplements, is critical when unraveling emerging etiologies of esophageal ulcerations.

DOES GALLIC ACID HAVE A POTENTIAL REMEDIAL EFFECT IN EXPERIMENTAL CORROSIVE BURN INJURY TO THE ESOPHAGUS?

Gallic acid, acting as an antioxidant, anti-precipitant and cytoprotective agent, was used as a possible remedial natural component for treating experimentally induced esophageal burn. Wistar rats (n=24) were divided into three groups. Control group was given 1 mL 0.9% NaCl. Experimental esophageal burn was induced with 1 mL 40% NaOH application to the esophagus in groups 2 and 3. Gallic acid® (20 mg/kg) was administered to the treated group via oral gavage for 10 days. Removed tissues were fixed and paraffin blocks were prepared. Histopathological examination was performed after the sections had been stained with hematoxylin-eosin. Tumor necrosis factor alpha and caspase-3 antibodies were used on immunohistochemical analysis. In the esophageal burn group, necrosis, degeneration and numerous apoptotic cells, as well as intense inflammatory cell infiltration and fibrosis in the muscle layer were observed under light microscope. In the treated group, remodeling of epithelial cells with marked reduction in the connective tissue collagen content was observed, as well as marked reduction in the volume of collagen and abundance of inflammatory cells in blood vessels. Gallic acid treatment may help heal esophageal burns and prevent complications.

Caustic ingestion leads to pneumonectomy and right colonic interposition, a unique case report

INTRODUCTION

Corrosive ingestion forms serious problem, with various outcomes depending on the time of diagnosis and treatment. We report here a case with rare and dangerous complications.

PRESENTATION OF CASE

A two-year-old girl came to our hospital, complaining of solids' dysphagia. Retrieving her medical history showed that she had ingested a corrosive liquid accidentally. Without knowing the nature of the ingested agent, the local doctor removed it, using nasal gastric tube. This procedure induced vomiting, which in turn led to more damage. She stayed in the area's hospital for 40 days with just supportive treatment. The radiological investigations suggested severe stenosis. The dilation was done, but the patient did not respond after three months of treatment. Therefore, a gastrostomy was done. The esophagus replacement was inevitable, but the parents refused the surgical approach. Three months later, she returned to our hospital complaining of a productive cough. The radiological investigations suggested destruction in the left lung with a high suspicion of tracheoesophageal fistula. The treatment was through a surgical approach by removing the damaged lung tissue and closing the tracheoesophageal fistula. The patient got better after a month of the surgery, which allowed us to replace the esophagus and close the tracheoesophageal fistula.

DISCUSSION

corrosive treatment varies a lot, depending on the patient's situation. Accurate treatment prevents severe and unexpected complications.

CONCLUSION

More stringent instructions should be enacted among medical providers, corrosive agents' producers, and the public to be more careful when dealing with corrosive chemicals.

Caustic esophageal stenosis: A case report of endoscopic dilatation with nasogastric tubes

The management of the esophageal strictures that may result from caustic ingestion has evolved over time, from surgical to endoscopic management. Dilation with nasogastric tubes may be a valuable alternative in places with limited resources.

Use of transoral carbon dioxide laser for supraglottic web from caustic ingestion in a 13 year old

A 13 year old male was referred to the Department of Otorhinolaryngology due to unsuccessful decannulation. At 2 years of age, patient accidentally ingested a caustic liquid alkali and underwent emergency tracheostomy, exploratory laparotomy, and tube gastrectomy. 11 years after, patient was seen at the outpatient department for decannulation. On nasopharyngolaryngoscopy, a supraglottic stenosis with a central 1-mm opening was visualized. Patient underwent transoral carbon dioxide laser excision of supraglottic stenosis. Fused aryepiglottic folds were released from the epiglottis. Patient was discharged well with no immediate complications and was successfully decannulated 1 month post operation with good voice outcome. No recurrence of stenosis at one year post operation. Accidental caustic ingestion commonly occurs in the pediatric age group. A frequent complication of accidental caustic ingestion is strictures. The use of transoral carbon dioxide laser in the surgical treatment of supraglottic stenosis is a suitable option for pediatric patients as this offer several advantages such as less post operative edema, good intraoperative control of hemorrhage, few post-operative complications and is less invasive compared to open laryngeal procedures. This case exhibits the importance of close monitoring for pediatric patients after caustic ingestion in order to diagnose complications earlier.

Use of Antibiotics in Poisonous Ingestions of Corrosives and Organophosphates: A Retrospective Cohort Study

The use of antibiotics following oral poisoning by corrosives and organophosphates is controversial. We assessed the clinical outcomes of using antibiotics in acute poisonous ingestion involving corrosives or organophosphates by conducting a retrospective cohort study of patients presenting to the emergency department following ingestion of corrosives or organophosphates who received either antibiotics or supportive care. The endpoints included clinical stability, length of stay (LOS), and mortality. Of 95 patients, 40 received antibiotics and 55 received supportive care. The median age was 2.1 and 2.7 years, respectively (p = 0.053). Bacterial growth was shown in only 2 of 28 cultures (both were respiratory), but with hospital-acquired organisms as it was shown ≥4 days post-admission. Clinical stability rates were 60% and 89.1% in the antibiotic and supportive care groups, respectively (p < 0.001). Median LOS was 3 vs. 0 days (p < 0.001), and no mortality was recorded. NG/G-tube placement was the only factor associated with clinical failure (OR, 20.97; 95% CI, 2.36-186.13). Antibiotic use was not associated with higher chances of clinical stability, which may suggest that their use was unnecessary. Clinicians are encouraged to use antibiotics wisely, and only in the presence of a clear indication of an infection. This study provides a basis for future prospective studies to confirm its findings.

Effectiveness of sucralfate in preventing esophageal stricture in children after ingestion of caustic agents

Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. The role of sucralfate in preventing stricture caused by caustic agents is controversial, and limited studies have been conducted in this field. We aimed to investigate the effect of sucralfate on preventing esophageal stricture in children. Sixty children with mean age of 36.69 ± 20.50 months and grade II B esophageal burns due to ingestion of caustic agents were enrolled in the study. In the intervention group, in addition to the usual treatment, sucralfate was administered orally at a dose of 80 mg/kg every 2 h for 3 days. For the control group, only the usual treatment was prescribed. Stricture development was compared between groups based on endoscopic and radiologic findings. Of the 60 patients enrolled in the study, 53 were examined. The incidence of esophageal stricture in the intervention group was significantly lower than in the control group (37% versus 67%, P-value = 0.042). In addition, the odds of esophageal stricture after sucralfate intervention was significantly reduced after adjustment for potential confounders (OR = 0.198, P-value = 0.031).  Conclusions: The results of this study showed that sucralfate may reduce the development of esophageal stricture in children when used to manage IIB esophageal burns due to ingestion of caustic agents. What is Known: • Ingestion of caustic agents by children is a serious health issue that can affect the patient for the rest of his life. • The role of sucralfate in preventing stricture caused by caustic agents is controversial and limited studies have been conducted in this field. What is New: • It seems that sucralfate significantly reduces the incidence of esophageal stricture following the ingestion of caustic agents in children compared to the control group. • We believe that the prognosis may be improved and the risk of stricture formation may be reduced with high doses of sucralfate therapy in grade IIB esophageal injury.

Endoscopic Grading as a Predictor to Develop Strictures in Corrosive Esophagitis in Children

INTRODUCTION

The incidence of corrosive esophagitis, also known as caustic esophagitis in children, is still increasing in developing countries, according to different clinical reports. Acids and alkalis are, in the same manner, involved in the pathogenesis of corrosive esophagitis in children. The aim of our study was to determine the incidence and endoscopic grading of corrosive esophagitis in a cohort of children from a developing country.

MATERIALS AND METHODS

We performed a retrospective analysis of all pediatric patients who were admitted for corrosive ingestion at Pediatric Clinic II, Emergency Hospital for Children, Cluj-Napoca, over 10 years.

RESULTS

A total of 22 patients consisting of 13 (59.09%) girls and 9 boys (40.91%) were found in the present research. The majority of children lived in rural areas (69.2%). The results of laboratory tests were not well correlated with the degree of the injury. White blood cell counts over 20,000 cells/mm³, an increase in the C-reactive protein level and hypoalbuminemia were noticed only in three patients with strictures. The lesions were associated with increased levels of the pro-inflammatory cytokines, including interleukin (IL)-2, IL-5 and Interferon-gamma. Severe late complications such as strictures have been noticed in children with grade 3A injuries. The endoscopic dilation was done after the six months endoscopy. None of the patients treated with endoscopic dilation required surgical intervention for esophageal or pyloric perforation or dilation failure. The majority of complications (such as malnutrition) were noticed in children with grade 3A injuries. In consequence, prolonged hospitalization has been required. The second endoscopy (done six months after ingestion) revealed stricture as the most common late complication (n = 13, 60.60%: eight patients with grade 2B and five with grade 3A).

CONCLUSION

There is a low incidence of corrosive esophagitis in children in our geographic area. Endoscopic grading is a predictor of late complications such as strictures. Grade 2B and 3A corrosive esophagitis are likely to develop strictures. It is crucial to avoid strictures and to prevent malnutrition.

Self-Poisoning With Household Bleach in an Elderly Man

Caustic self-poisoning is a major health hazard, which affects any age, but is particularly serious among the elderly. Household bleach is a caustic that contains 3% to 6% sodium hypochlorite solution, one of the most common agents in unintentional caustic poisoning. In this clinical case, we present a household bleach self-poisoning by an older man with no relevant medical history. He presented with extensive burns on the oral cavity mucosa and tongue, requiring orotracheal intubation by video laryngoscopy. He was then admitted to the intensive care unit, where he evolved poorly. Given the poor prognosis and the lack of physiological reserve for the invasiveness required for a surgical approach, a conservative strategy was chosen after a multidisciplinary team discussion. With the conservative strategy, the patient survived, being discharged to the general ward after one month, where he underwent a Stamm gastrostomy and placement of a percutaneous endoscopic gastrostomy. In the follow-up consultation three months later, the patient was found to be weakened, with high frailty status, presenting anxiety, depression, and causing high family burden.

[The role of endosonography in the treatment of chemical ulcerative-necrotic burns of the esophagus]

The authors present ultrasonography-assisted endoscopic diagnosis of chemical burn of the esophagus. This method early predicted decompensated cicatricial stenosis of the esophagus that was valuable to determine treatment strategy. Preventive mini-invasive endoscopic percutaneous gastrostomy provided adequate enteral nutrition in a patient with decompensated esophageal stenosis before reconstructive surgery.

Nutritional Experiences of Parents of Children Who Had Gastric Transposition Surgery

This study aimed to understand the postoperative nutritional experiences of parents of children who had undergone gastric transposition surgery after corrosive esophageal injury. The study had a descriptive qualitative research design, and used a structured interview form as a result of the COVID-19 pandemic. The population of the study consisted of the parents of 12 children who had undergone gastric transposition surgery at the pediatric surgery clinic of a university hospital in an urban area in Turkey. Thematic analysis was conducted on the transcripts using the MAXQDA program. Four main themes emerged and five supporting sub-themes were identified. The main themes were what we experienced in the postoperative nutrition process, coping with how we live, what we want to know, and our recommendations to healthcare professionals. Family-centered care should be a main focus when caring children who have had gastric transposition surgery, and children and their parents should be supported by a multidisciplinary team.

Clinical analysis of pipeline dredging agent poisoning: A case report

BACKGROUND

Pipeline dredging agents are new household deep cleaning products used to dredge blockages in kitchen and bathroom pipeline caused by grease, hair, vegetable residue, paper cotton fibre, and other organic substances. Pipeline dredging agents are corrosive chemicals that can cause poisoning through corrosive damage to the digestive tract; however, this has not been reported clinically. Therefore, this report emphasises that oral pipeline dredging agent poisoning can cause corrosive damage to the digestive tract and may have serious health consequences.

CASE SUMMARY

A 68-year-old man consumed liquor (200 mL) at approximately 13:00 on April 22, 2021. At approximately 16:00, his family found him unresponsive with blackened lips, blood spots in the corners of the mouth, and blood stains on the ground, as well as an empty bottle of a pipeline dredging agent. One hour later, he was admitted to the emergency department of a local hospital. Considering the empty bottle, he was suspected to have sustained severe corrosive damage to the digestive tract and was transferred to our department at 23:15 on April 22, 2021. He developed dysphagia and intermittent fever and experienced difficulty in opening his mouth throughout his hospital stay. The patient’s condition gradually stabilised. However, he suddenly developed respiratory failure on day 12, and endotracheal intubation and ventilator-assisted ventilation were performed. However, the patient died after 1.5 h despite emergency rescue efforts.

CONCLUSION

Pipeline dredging agents are highly corrosive and may cause corrosive damage to the digestive tract and asphyxia upon consumption.

Utilization of chest tube as an esophagus stent in pediatric caustic injuries: A retrospective study

BACKGROUND

The management of caustic esophageal burns in the pediatric population has changed over the years, while the most optimal management with regards to effectiveness, availability, and cost-beneficent stays controvertible.

AIM

To describe how to utilize a chest tube for esophageal stenting in pediatrics.

METHODS

Data regarding the etiology, treatment, and complications of caustic injury in pediatrics over 10 years was collected retrospectively. Furthermore, data regarding the patient's follow-up who underwent esophageal chest tube (ECT) were collected. The ECT was prepared by carving a narrowed section in the chest tube while maintaining the radiopaque section. The ECT will then be positioned from the cricopharyngeal and exited through the nostril and fixed on the patient's cheek.

RESULTS

During the period of our study, data from 57 patients with an average age of 2.5 years (range 1-12; SD = 1.7) were obtained. The results showed that 89% of esophageal injury was due to alkaline and 9.4% were caused by acidic agents. The treatment methods showed that 29 patients (50.8%) recovered with dilatation alone. In 16 patients (28.06%), the esophageal repair was performed by using the colon, and in 5 patients (8.7%), other surgical methods were used and in 7 patients (12.2%), the ECT stents were used. ECT was inserted in 7 cases with a mean age of 2 (range: 1.5-3) years who were classified as grade IIB or III. Grading was performed by endoscopy assessment on the first day. Antibiotics and corticosteroids were administrated as initial medical management for all patients. ECT implantation was done during the first 8 d for 5 out of 7 cases (mean: 3.8 d). For the 2 patients, ECT was used after 27 (patient 6) d and 83 (patient 7) d. The reason for late stenting in these patients was a postponed referral to our center, in which patient 7 even received 4 dilation episodes before visiting our center. ECT was removed after an average of 44 d in the first 5 patients, while in the other 2 patients (6 and 7) was 2 and 1 wk, respectively. There was no complication related to, or failure of, stent placement. It is worth mentioning that none of the 7 ECT cases required gastrostomy or jejunostomy.

CONCLUSION

The ECT method introduced in our study can be used as a broadly available, economic, and easy-use facility for esophageal stenting, particularly in developing countries and emergency departments which have limited access to modern equipment. Further multicenter studies with higher volume patients are required for further deployment of this method.

Ingestion poisoning related lung injury- a pictorial review

Poison ingestion is a medical emergency requiring immediate care in the emergency department. Respiratory symptoms with ingested poisons can occur due to aspiration, cardiopulmonary effects, or direct lung toxicity due to injury of the alveolar epithelium. Chest imaging (chest radiographs/CT) is usually performed in the emergency setting to evaluate such symptoms. It is often impossible to elicit the nature of the poison ingested by the patients due to their unconscious state. Identification of the culprit poison can expedite the patient's management towards a specific antidote or help understand the underlying mechanism causing the pulmonary symptoms. The imaging manifestations depend on the underlying mechanisms, varying for each ingested poison, forming an imaging signature which has not been adequately discussed in existing literature. Poisons like paraquat and organophosphate are important to differentiate as indiscriminate use of oxygen therapy in the former can exacerbate the lung injury caused by redox cycling. In this pictorial assay, we present the chest imaging spectrum of commonly ingested poisons, and further suggest algorithmic approach towards identification of common poisons based on their chest imaging.

Endoscopy is the main choice of handling caustic ingestion.

•

Do not place a nasogastric tube on the caustic ingestion before endoscopy.

•

Surgery is considered when x-ray results show damaged abdominal and chest.

Caustic ingestion in children treated at a tertiary centre in South Africa: can upper endoscopy be omitted in asymptomatic patients?

PURPOSE

Considering that clinical presentation and gastrointestinal tract (GIT) injuries post-caustic ingestion vary in children, this study aims to establish whether a correlation exists between clinical presentation and endoscopic findings.

METHODS

This retrospective study comprised patients referred to a paediatric surgical unit between 2016 and 2018 within 72 h post-caustic ingestion. Data collected included caustic agents ingested, clinical presentation, endoscopic findings and management. Oesophageal injuries were graded according to the Zargar's endoscopic classification and gastric injuries classified as mild to severe.

RESULTS

Fifty patients with a mean age of 2.4 years were managed during the study period. Potassium permanganate (KMNO4) was the most frequently ingested substance in 27 (54%) patients. All 30 (60%) asymptomatic patients had no positive endoscopic findings regardless of clinical signs. Among the symptomatic patients (n = 20), 15 (75%) had oesophageal injuries (p = 0.01). Stridor was associated with a higher grade of oesophageal injury (p = 0.007).

CONCLUSIONS

Clinical signs and symptoms post-caustic ingestion correlated with endoscopic findings in our study. Endoscopy can be safely omitted in asymptomatic patients, including those with isolated staining secondary to KMNO4 ingestion. Symptomatic patients should have an endoscopy performed within 48-72 h of the insult to diagnose injuries.

Esophageal regeneration following surgical implantation of a tissue engineered esophageal implant in a pediatric model

Diseases of the esophagus, damage of the esophagus due to injury or congenital defects during fetal esophageal development, i.e., esophageal atresia (EA), typically require surgical intervention to restore esophageal continuity. The development of tissue engineered tubular structures would improve the treatment options for these conditions by providing an alternative that is organ sparing and can be manufactured to fit the exact dimensions of the defect. An autologous tissue engineered Cellspan Esophageal Implant^TM (CEI) was surgically implanted into piglets that underwent surgical resection of the esophagus. Multiple survival time points, post-implantation, were analyzed histologically to understand the tissue architecture and time course of the regeneration process. In addition, we investigated CT imaging as an “in-life” monitoring protocol to assess tissue regeneration. We also utilized a clinically relevant animal management paradigm that was essential for long term survival. Following implantation, CT imaging revealed early tissue deposition and the formation of a contiguous tissue conduit. Endoscopic evaluation at multiple time points revealed complete epithelialization of the lumenal surface by day 90. Histologic evaluation at several necropsy time points, post-implantation, determined the time course of tissue regeneration and demonstrated that the tissue continues to remodel over the course of a 1-year survival time period, resulting in the development of esophageal structural features, including the mucosal epithelium, muscularis mucosae, lamina propria, as well as smooth muscle proliferation/migration initiating the formation of a laminated adventitia. Long term survival (1 year) demonstrated restoration of oral nutrition, normal animal growth and the overall safety of this treatment regimen.

Sequelae of Corrosive Injury in Children: An Observational Study

Aim

This study aims to determine the sequelae of corrosive ingestion in children.

Methods

A retrospective study was conducted in the Department of Pediatric Surgery at a Tertiary Center. The children presenting between January 2015 and December 2020 with a history of ingestion of caustic agents were included in the study.

Results

A total of 26 children were included in the study. The children with suicidal attempts were significantly older than those who ingested the corrosive agents accidentally (14.2 ± 1.9 years vs. 6 ± 3.3 years; P < 0.01; Student's t-test). Sixteen (62%) children had esophageal strictures, 8 (31%) had pyloric strictures, and a child (4%) had both esophageal and gastric strictures. Eight (31%) children required an initial feeding jejunostomy and 6 (23%) required a feeding gastrostomy as they had significant weight loss on presentation. Eleven (65%) esophageal strictures responded to the dilatation regimen and are symptom-free on follow-up. Three (18%) children with esophageal stricture underwent esophageal replacement. Eight (31%) children had a pyloric stricture and all of them were treated with a modified Billroth I gastro-duodenostomy. The children who presented after 2 months were found to have a significantly increased need for esophageal replacement (3/9 vs. 0/17; P = 0.03; Fischer's exact test).

Conclusion

The corrosive ingestion in children is associated with higher morbidity. The sequelae include esophageal and antro-pyloric strictures. A feeding gastrostomy or jejunostomy was required in more than half of the patients. The children presenting after 2 months of ingestion were associated with an increased need for esophageal replacement.

Battery Ingestion in Children, an Ongoing Challenge: Recent Experience of a Tertiary Center

INTRODUCTION

Morbidity related to childhood battery ingestions (BI) has increased recently due to the expanding use of larger lithium cells. A prompt endoscopic removal is vital to prevent severe complications in cases of esophageal batteries (EB).

MATERIALS AND METHODS

A retrospective, descriptive study of admissions for BI requiring endoscopic removal in a tertiary hospital's pediatric emergency department (Jan. 2011/Dec. 2020).

RESULTS

We had 35 cases, with an increasing incidence in the last 6 years; median age, 26 m (8 m-10 years), witnessed ingestion in 86%. On the X-ray: 14 (40%) had an EB, 21 (60%), a gastric battery (GB). Symptoms were present in 57% (100% EB/24% GB), and vomiting was the most frequent (50%). Endoscopy revealed: EB, 13 (37%); GB, 17 (49%); duodenal battery, 1 (3%); no battery, 4 (11%). Median time to removal: EB, 7 h (2 h-21days); GB, 12 h (2 h-3 days). All the patients with EB on the X-ray (14) had severe mucosal injury (Zargar classification): Grade IIIa, 7 (50%); IIIb, 5 (36%); IV, 2 (14%). CT-scan showed perforation in 2 patients (total, 4; 29% of EB). In patients with GB (21), 14 (67%) had mucosal damage; 13 (93%), mild (< Grade III, two esophageal erosions); 1 (7%) IIIa (esophageal ulceration). A statistically significant association between exposure time, younger age or battery size and severity of endoscopic lesions was found in EB location. There were no mortality cases. Acute complications occurred in 57% of EB: infection, 50%; perforation, 29%; pneumomediastinum/stridor, 14%; pneumothorax/subglottic stenosis/hemodynamic instability, 7 vs. 0% GB. Stenosis subsequently developed in 6 (43%) of EB: mild, 4 cases (29%); severe, 2 cases (14%, one resolved after endoscopic dilation; one needed a gastrostomy and esophagocoloplasty).

CONCLUSION

We verified recent increase in admissions due to battery ingestions and associated complications, despite the availability of an emergency pediatric endoscopy team. The patients with EB had more severe mucosal injury and poorer short/long-term outcomes. Children with GB had milder lesions, although the presence of a GB did not exclude esophageal injury. The availability of actual data from national referral centers will support advocacy efforts among stakeholders, including industry representatives and policy makers, in preventing worldwide button battery injury.

Household cleaning products poisoning in a pediatric emergency center: A 10- year cross-sectional study and literature review

BACKGROUND

Poisoning by household cleaning products(HCPs) is common in children. Some HCPs are toxic and may cause severe complications. We assessed HCP poisonings treated in a pediatric emergency department(PED).

METHODS

This was a retrospective study of patients aged under 18 years with HCP poisoning admitted to the largest PED in Taiwan from 2011 to 2020 were recruited.

RESULTS

The records over a 10-year period from 103 children admitted to the PED because of HCP poisoning(70 boys [68%] and 33 girls [32%]), mean age 3.54 years(standard deviation [SD] = 3.15 years) were evaluated. Most poisonings were unintentional(99%, n = 102) and occurred at home(96%, n = 99). The HCPs included alkaline(74%, n = 76), acidic(25%, n = 26), and neutral(1%, n = 1) agents. Most were orally ingested(86%, n = 89). Panendoscopy was performed in 25 patients(24%), and the endoscopic(Zargar) grade was used to determine the severity of injury. Medications(steroids [9%, n = 9], antibiotics [10%, n = 10], or antacids [30%, n = 23]) were prescribed. Alkaline HCP ingestion induced severe esophageal injury(p = 0.04) and esophageal stricture(p = 0.04). Five patients(5%) exhibited esophageal strictures and required balloon dilation. On multivariate analysis, alkaline HCP ingestion(p = 0.04), severe esophageal caustic injury(Zargar grade ≥ 3) (p < 0.001), and medications(steroids [p < 0.001], antibiotics [p < 0.001], and antacids [p = 0.001]) were associated with esophageal stricture.

CONCLUSION

Alkaline HCP ingestion and severe esophageal caustic injury(Zargar grade ≥ 3) were associated with esophageal stricture. Physicians tended to prescribe medications(steroids, antibiotics, or antacids) for patients with severe esophageal injuries to reduce the risk of esophageal stricture. The usefulness of these medications requires further study.

The Ominous Ouzo Party - A Case Series of Four Patients with Accidental Alkali Ingestion

BACKGROUND

Ingestion of alkaline fluids is a common problem, which can lead to perforations, strictures and malignancy. We present a rare case series of several patients who accidentally ingested the same alkaline substance in different doses.

METHODS

We investigated four patients with accidental ingestion of dishwashing liquid. All patients underwent gastroscopy within 24h after inpatient admission. Gastroesophageal lesions were classified according to the Zargar classification for corrosive ingestions.

RESULTS

Esophagogastric lesions were predominantly found at the distal esophagus and the small curvature of the stomach. The severity of these lesions ranged from mild erosions (Zargar 2A) to marked necrosis (Zargar 3A). Our data suggest that the degree of these lesions correlated with the amount of ingested toxin and duration of the inpatient stay. However, a low symptom severity or inconspicuous otolaryngologic examination did not exclude severe gastroesophageal lesions.

CONCLUSION

Our data suggest that the severity of gastroesophageal lesions correlates with the amount of ingested alkaline substance. Symptom burden and an otolaryngologic examination are not sufficiently predictive for the severity of gastroesophageal lesions. The composition and quantity of the swallowed liquid should be determined.

Foreign Body and Caustic Substance Ingestion in Childhood

Foreign body and caustic substance ingestion in childhood are common and require accurate and timely diagnosis to provide appropriate management consistent with the ingested substance/foreign body and clinical presentation as well as the associated risk status to prevent significant complications and morbidity. The aim of this paper was to present foreign body and caustic ingestion in childhood in terms of epidemiology, pathophysiology, diagnostic work-up and appropriate management and potential complications in accordance with clinical presentation and the type of ingested substance/foreign body.

Tubed Anterolateral Thigh Free Flap for Pharyngoesophageal Reconstruction

Caustic ingestions can severely injure the upper and lower aerodigestive tract, resulting in detrimental mucosal changes both acutely and chronically. Injuries are most severe following alkaline ingestion. Esophagectomy is often recommended in patients with high-grade esophageal injuries to mitigate the risk of perforation. Esophageal reconstruction after these injuries is often delayed, and staged, allowing adequate tissue stabilization before further manipulation. Here, we report on a 25 year-old woman who presented with a high-grade caustic esophageal injury following the ingestion of an alkaline drain cleaner. She underwent an emergent thoracic esophagectomy, gastrectomy and a cervical salivary esophagostomy. Post-operatively, she developed supraglottic and hypopharyngeal strictures, but maintained a functional larynx. She subsequently underwent a staged, extrathoracic total esophageal reconstruction using an anterolateral thigh (ALT) myocutaneous free flap with laryngeal preservation. Although serial esophageal dilatations and trans-oral laser procedures for pharyngeal strictures were required, she was able to maintain the ability to swallow.

Corticosteroid injection of impassable caustic esophageal strictures without dilatation: Does it pave the way to interval endoscopic dilatation?

BACKGROUND/PURPOSE

Endoscopic dilatation of caustic esophageal stricture is the mainstay of therapy. The need for esophageal replacement has decreased over the past decades owing to advancement in techniques of dilatation. In this study, we aimed to assess our results of four-quadrant corticosteroid injection of impassable caustic esophageal strictures followed by a trial endoscopic dilatation.

METHODS

During the period from June 2003 to May 2017, in 340 patients in whom a trial of endoscopic dilatation after corrosive ingestion failed, corticosteroid was injected in 4 quadrants at the site of the stricture in the same setting. After 2 weeks, another trial of endoscopic dilatation was done.

RESULTS

Out of the 340 patients with failed first trial of endoscopic dilatation followed by four-quadrant corticosteroid injection, the second trial of endoscopic dilatation, after 2 weeks, was possible in 255 patients (75%). In the remaining 85 patients (25%), the endoscope could not pass and they were candidate for esophageal replacement.

CONCLUSIONS

Four-quadrant corticosteroid injection of impassable caustic esophageal stricture followed by endoscopic dilatation is a minor procedure which decreased the need of a major procedure to replace the injured esophagus.

Assessing the Degree of Acute Esophageal Injury Secondary to Corrosive Intake: Insights From a Public Sector Hospitals of a Developing Country

Background

Caustic ingestion continues to be a significant problem worldwide especially in developing countries and particularly in the age group of under six years. Ingestion of caustic substances is a medical emergency in both the adult and pediatric population and is associated with high morbidity and mortality. The ingestion of caustic substances induces an extensive spectrum of injuries to the aerodigestive tract, which includes extensive necrosis and perforation of the esophagus and stomach.

Objectives

The main aims were to determine upper and lower esophageal injuries associated with corrosive intake and to compare esophageal injury with age and gender.

Rationale

Once we’ll find the extent and severity of esophageal injury associated with corrosive intake within 24 hours, we’ll be able to manage the case timely and to limit further complications and disabilities.

Materials and Methods

This descriptive cross-sectional study was conducted on 150 patients who presented with corrosive ingestion and underwent urgent endoscopic evaluation. Data were collected using self-designed pro forma. Endoscopic findings were classified according to the Zargar classification. A descriptive analysis of study variables was performed using SPSS v.21.0 (IBM Corp., Armonk, NY, USA). The chi-square test was used, and a p-value of less than 0.05 was considered statistically significant.

Results

Out of 150 patients under study, 103 (68.7%) were females and 47 (31.3%) were males. The most prevalent age group presenting with corrosive intake was found to be between 21 and 34 years of age (43.3%) in both genders. The most common part of the esophagus prone to corrosive insult is the upper esophagus (99.3%), whereas, regarding severity, the lower esophagus has more severe injuries (predominant being stage 2B, i.e., 32%). There are no statistically significant differences in esophageal injuries in different age groups (upper esophageal injury: 0.319; lower esophageal injury: 0.696) and genders (upper esophageal injury: 0.769; lower esophageal injury: 0.752).

 Conclusions

Most of the patients under study belong to the female gender and teen and younger age group. The predominant upper esophageal injury as a result of corrosive intake is stage 0 injury, and the least common is found to be stage 1 injury. The predominant lower esophageal injury as a result of corrosive intake is stage 2B injury, whereas the least common is found to be stage 4 injury.

Corrosive injury of the upper gastrointestinal tract: the evolving role of a radiologist

Corrosive injury is a devastating injury which carries significant morbidity. The upper gastrointestinal tract is predominantly affected with severity ranging from mild inflammation to full thickness necrosis which may result in perforation and death. Among the complications, stricture formation is most common, causing dysphagia and malnutrition. Endoscopy has a pivotal role in the diagnosis and management, with a few shortcomings. Imaging has an important role to play. Besides radiography, there is an increasing role of CT scan in the emergency setting with good accuracy in identifying patients who are likely to benefit from surgery. Further, CT scan has a role in the diagnosis of complications. Oral contrast studies help in assessing the severity and extent of stricture formation and associated fistulous complications in the subacute and chronic phase. The scope of intervention radiology for this condition is increasing. Fluoroscopy-guided balloon dilatation, drainage of collections or mucoceles, endovascular embolization of point bleeders, placement of feeding jejunostomy and image-guided biopsy are among the procedures that are being performed. Through this review we aim to stress the role the radiologist plays in the diagnosis and follow-up of these patients and in performing radiological interventions. Besides this, we have also highlighted few salient points to help understand the pathophysiology and management of such injuries which is paramount to ensure a good long-term outcome.

Corrosive Esophagitis and Gastritis Induced by Glutaraldehyde Ingestion

Corrosive esophagitis and gastritis are characterized by caustic damage due to ingestion of chemical agents. Caustic agents cause tissue destruction through liquefaction or coagulation reactions. Here, we report a case of corrosive esophagitis and gastritis caused by accidental ingestion of glutaraldehyde in Korea. A 62-year-old man presented to the emergency department 8 hours after ingesting glutaraldehyde, which is widely used for the prevention of foot-and-mouth disease in pigs. Urgent endoscopic examination revealed severely damaged mucosae of the esophagus and stomach. With conservative treatment, the patient’s condition was improved, and he was discharged on the 35th day of admission.

Presentation and management outcome of childhood corrosive oesophageal injury in Benin City

BACKGROUND

Corrosive ingestion in children occurs usually at home and frequently results in debilitating strictures. Prevention and early intervention programs are very important for good outcomes.

AIMS AND OBJECTIVES

This study aims at examining the immediate causative factors and problems of this subset of patients with a special focus on treatment and outcome. This study was to audit the management of patients in the paediatric age group who presented for treatment with history and sequelae of corrosive ingestion seen by the cardiothoracic unit of the University of Benin Teaching Hospital from January 2005 till December 2018.

MATERIALS AND METHODS

This is a 14year retrospective study of patients that presented with oesophageal burn injuries from ingestion of corrosive agents to the Cardiothoracic Unit at the University of Benin Teaching Hospital between January 2005 and December 2018. Essentially the first 5years were retrospectively included but the subsequent years were prospective. All available medical data on these patients were retrieved and studied for epidemiological, clinical and operative procedures and outcome.

RESULTS

A total of 49 patients were seen and admitted during the period under review. Male (29) : Female (20) ratio was 1:1.4 Mean age was 4.7±4.8 years with a range of 1-16years, The males presented earlier and had worse strictures as well as more surgical procedures. Caustic soda preparations ingested more (93.9%), all ingestions were within the household setting, and all had first aid given by way of oral palm oil. Only two (4.1%) ingested acids with only one flat battery ingestion. 45.5% of the patients had dilatation only and of these 50% recovered after 3 sessions and required no more sessions. A further 50% were lost to follow up. 38.8% had oesophageal replacement with colon following oesophagectomy.

CONCLUSION

In conclusion, corrosive oesophageal stricture is a debilitating disease in children and affects males more, but it is treatable by multiple dilatations and oesophageal replacement with colon. Prevention should be actively pursued as well as early intervention.

A prospective randomized controlled trial of omeprazole for preventing esophageal stricture in grade 2b and 3a corrosive esophageal injuries

OBJECTIVES

Esophageal stricture is a significant complication of grade 2b and 3a esophageal injuries and causes much patient suffering. Preventing strictures would be beneficial to patients but there are currently no proven effective drugs. This study aimed to evaluate the effect of omeprazole for preventing esophageal stricture in adults with grade 2b and 3a corrosive esophageal injuries.

METHODS

This study was an open single-center prospective randomized controlled trial that took place from April 2018 to January 2020. Patients were randomized to standard treatment or 80 mg/day intravenously × 3 days followed by 40 mg/day orally for 4 weeks. They were endoscoped at baseline and 4 weeks post discharge. Strictures were confirmed radiologically.

RESULTS

20 patients were enrolled: 15 with grade 2b and five with grade 3a injuries. Standard care and omeprazole groups numbered 10 each. At 1 month, seven and two patients developed strictures in the standard and omeprazole groups, respectively, p = 0.024, for a risk reduction of 71.4%.

CONCLUSIONS

Omeprazole reduced the risk of short-term developing esophageal strictures following grade 2b and 3a corrosive esophageal injuries. Larger studies are needed to reconfirm this finding. Thai Clinical Trials Registry (TCTR) number TCTR20190504001.

Catastrophic Caustic Ingestion: A Case Report

Introduction

The majority of oral ingestion of caustic material by adults is intentional, and the aftermath varies widely with potentially fatal results. Injuries range from superficial burns of facial and oropharyngeal structures to extensive necrosis of the gastrointestinal tract. Management focuses on the identification of the ingested substance and prompt treatment and supportive care of the multiple complications stemming from the ingestion. Complications following caustic ingestion include both immediate and long term.

Case presentation

A fifty-seven-year-old man presented following intentional ingestion of drain cleaner. The patient was intubated and underwent emergent esophagogastroduodenoscopy [EGD], which revealed extensive damage to his oesophagus and stomach. He survived his initial injury but had a prolonged hospital course and ultimately died after developing tracheoesophageal and bronchooesophageal fistulas which were too extensive for surgical repair.

Conclusion

The sequelae of caustic ingestion can be minor or severe, both immediate and delayed. Despite appropriate prompt management and supportive care, patients may die as a result of the initial injury or subsequent complications.

Corrosive substances ingestion: a review

Corrosive chemical substance ingestions are a major problem, especially in developing countries, but also in developed countries such as the United States, France, and Belgium. Ingestions may be deliberate as suicide attempts (mostly in adolescents and adults) or accidental (mostly in children). The results can be devastating in terms of individual suffering and disability, but also in terms of resource utilization and costs. In developing countries, outcomes may be worse because of limited medical/surgical resources. Common sequelae include gastrointestinal (GI) tract (esophagus, stomach, pylorus, and duodenum) stricture formation, GI tract perforation, and hemorrhage. Systemic effects may also occur, such as disseminated intravascular coagulation (DIC), multi-organ system failure, and sepsis. Various interventions in the acute phase to reduce the severity of injury have been attempted, but there are no large controlled clinical trials to demonstrate efficacy. Dilation therapy in various forms is commonly used for the treatment of strictures and a variety of surgical procedures including esophagectomy and delayed replacement may be required in severe corrosive injury cases.

Evaluation of corrosive poisoning in adult patients

OBJECTIVE

To evaluate the demographic characteristics, endoscopy results, emerging complications and the final status of caustic intake cases admitted to our emergency department.

METHOD

This study is a retrospective one concerning patients admitted to our emergency department due to caustic ingestion. Demographic characteristics of the patients, complaints while applying to the hospital, physical examination findings, the purpose of caustic intake, the characteristics of corrosive substance taken, times of endoscopy following admission to the emergency department, follow-up times in the emergency department, endoscopic staging and outcome. The data were analyzed through IBM SPSS Statistics Base 22.0 package program.

RESULTS

Seventy four patients participated in the study. 83.8% of corrosive substance intake cases were accidental and 16.2% cases were suicidal intention. While 60.8% of the corrosive substances taken had alkaline property, 36.5% were acidic and 2.7% were found to be unknown substances. 50% of the corrosive substance intakes were sodium hypochlorite. It was seen that endoscopy was performed in 59 patients who accepted endoscopy within an average of 244.07 min after admission to the emergency department. While no damage could be seen in 55.9% of patients following endoscopy, the most common injury was Grade 1 (35.6%).

CONCLUSION

Corrosive substance intake is a rare but potentially devastating poisoning with high morbidity and mortality. Mucosal injury begins within minutes following corrosive intake. Therefore, early endoscopy is helpful in assessing the degree of injury and early discharge from hospital.
