Abstract
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.

Abstract
BACKGROUND Caustic ingestion is associated with long-term sequelae like esophageal stricture, gastric cicatrization, and long-term risk of dysplasia or even carcinoma. However, only a few small studies have explored histopathological aspects of caustic-induced esophageal/gastric injury. MATERIALS AND METHODS We retrospectively evaluated specimens of patients undergoing surgery due to caustic ingestion-related complications from 2008 to 2020. Pathological examination was conducted by two independent gastro-pathologists to evaluate the extent and depth of the caustic injury, presence or absence of tissue necrosis, type and degree of inflammation, or presence of any dysplastic cells. RESULTS A total of 54 patients underwent surgical exploration during the inclusion period and complete details of 39 specimens could be retrieved. The mean age of the included patients was 28.66 ± 9.31 years and 25 (64.1%) were male. The majority of patients (30; 76.9%) had a history of caustic ingestion more than three months before the surgery and the presence of long or refractory stricture was the most common indication for the surgery (20; 51.28%). In the resected specimen, a majority of patients had superficial esophageal or gastric ulcer (90.6%; 60.0%), transmural inflammation (68.8%; 65.6%), transmural fibrosis (62.5%; 34.4%), and hypertrophied muscularis mucosa (78.13%; 53.3%). However, none of the patients had dysplasia in the resected esophageal or gastric specimens. CONCLUSION Caustic ingestion leads to mucosal ulceration, transmural inflammation, and transmural fibrosis which might be the reason for refractory stricture in such patients.

Enlarging the thermal coagulation volume during thermochemical ablation with alternating acid-base injection by shortening the injection interval: A computational study. COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2024; 243:107866. [PMID: 37865059 DOI: 10.1016/j.cmpb.2023.107866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 10/12/2023] [Accepted: 10/13/2023] [Indexed: 10/23/2023]
Abstract
BACKGROUND AND OBJECTIVES Thermochemical ablation (TCA) is a cancer treatment that utilises the heat released from the neutralisation of acid and base to raise tissue temperature to levels sufficient to induce thermal coagulation. Computational studies have demonstrated that the coagulation volume produced by sequential injection is smaller than that with simultaneous injection. By injecting the reagents in an ensuing manner, the region of contact between acid and base is limited to a thin contact layer sandwiched between the distribution of acid and base. It is hypothesised that increasing the frequency of acid-base injections into the tissue by shortening the injection interval for each reagent can increase the effective area of contact between acid and base, thereby intensifying neutralisation and the exothermic heat released into the tissue. METHODS To verify this hypothesis, a computational model was developed to simulate the thermochemical processes involved during TCA with sequential injection. Four major processes that take place during TCA were considered, i.e., the flow of acid and base, their neutralisation, the release of exothermic heat and the formation of thermal damage inside the tissue. Equimolar acid and base at 7.5 M was injected into the tissue intermittently. Six injection intervals, namely 3, 6, 15, 20, 30 and 60 s were investigated. RESULTS Shortening of the injection interval led to the enlargement of coagulation volume. If one considers only the coagulation volume as the determining factor, then a 15 s injection interval was found to be optimum. Conversely, if one places priority on safety, then a 3 s injection interval would result in the lowest amount of reagent residue inside the tissue after treatment. With a 3 s injection interval, the coagulation volume was found to be larger than that of simultaneous injection with the same treatment parameters. Not only that, the volume also surpassed that of radiofrequency ablation (RFA); a conventional thermal ablation technique commonly used for liver cancer treatment. CONCLUSION The numerical results verified the hypothesis that shortening the injection interval will lead to the formation of larger thermal coagulation zone during TCA with sequential injection. More importantly, a 3 s injection interval was found to be optimum for both efficacy (large coagulation volume) and safety (least amount of reagent residue).

Abstract
Thermochemical ablation (TCA) is a thermal ablation therapy that utilises heat released from acid-base neutralisation reaction to destroy tumours. This procedure is a promising low-cost solution to existing thermal ablation treatments such as radiofrequency ablation (RFA) and microwave ablation (MWA). Studies have demonstrated that TCA can produce thermal damage that is on par with RFA and MWA when employed properly. Nevertheless, TCA remains a concept that is tested only in a few animal trials due to the risks involved as the result of uncontrolled infusion and incomplete acid-base reaction. In this study, a computational framework that simulates the thermochemical process of TCA is developed. The proposed framework consists of three physics, namely chemical flow, neutralisation reaction and heat transfer. An important parameter in the TCA framework is the neutralisation reaction rate constant, which has values in the order of 108 m3/(mol⋅s). The present study will demonstrate that since the rate constant impacts only the rate and direction of the reaction but has little influence on the extent of reaction, it is possible to replicate the thermochemical process of TCA by employing significantly smaller values of rate constant that are numerically tractable. Comparisons of the numerical results against experimental studies from the literature supports this. The aim of this framework is for researchers to advance and develop TCA to gain an in-depth understanding of the fundamental mechanisms of TCA and to develop a safe treatment protocol of TCA in the hope of advancing TCA into clinical trials.

Abstract
Children constitute 80% of all corrosive ingestion cases. The majority of this burden is contributed by developing countries. Accidental ingestion is common in younger children (< 5 years) while suicidal ingestion is more common in adolescents. The severity of injury depends on nature of corrosive (alkali or acid), pH, amount of ingestion and site of exposure. There are multiple doubts and dilemmas which exist in management of both acute ingestion and chronic complications. Acute ingestion leads to skin, respiratory tract or upper gastrointestinal damage which may range from trivial to life threatening complications. Esophagogastroduodenoscopy is an important early investigation to decide for further course of management. The use of steroids for prevention of stricture is a debatable issue. Upper gastrointestinal stricture is a common long-term sequelae of severe corrosive injury which usually develops after three weeks of ingestion. The cornerstone of management of esophageal strictures is endoscopic bougie or balloon dilatations. In case of resistant strictures, newer adjunctive therapies like intralesional steroids, mitomycin and stents can be utilized along with endoscopic dilatation. Surgery is the final resort for strictures resistant to endoscopic dilatations and adjunctive therapies. There is no consensus on best esophageal replacement conduit. Pyloric strictures require balloon dilatation , failure of which requires surgery. Patients with post-corrosive strictures should be kept in long term follow-up due to significantly increased risk of carcinoma. Despite all the endoscopic and surgical options available, management of corrosive stricture in children is a daunting task due to high chances of recurrence, perforation and complications related to poor nutrition and surgery.

Abstract
Ingestion of caustic substances, whether accidental or for the purpose of suicide, can cause severe lesions of the lips, oral cavity, pharynx, upper gastrointestinal system, and upper airways. In particular, caustic agents could be responsible for severe esophageal injuries resulting in short- and long-term complications. Because of these important clinical implications, timely diagnosis and appropriate management are crucial. In the evaluation of esophageal injuries, thoraco-abdominal computed tomography (CT) is preferable to endoscopy as it avoids the risk of esophageal perforation and allows the evaluation of esophageal injuries as well as of the surrounding tissue. In this review, we report CT findings of esophageal injuries and possible related thoracic complications caused by caustic ingestion.

Abstract
UNLABELLED Corrosive ingestion remains a common problem in developing countries, such as India due to the lack of strict laws that regulate the sale of caustics. While appropriate treatment of the acute phase can mitigate tissue damage improper management of the acute corrosive injury is widely prevalent due to the limited experience of the individual physicians in managing this condition. The aim of this review is to summarize the epidemiology and pathophysiology of corrosive ingestion, principles in the management of acute phase injury, long-term effects of caustic ingestion, and prevention of corrosive ingestion.

Abstract
Esophageal stricture is a major secondary complication of ingesting caustic agents. We examined our experiences with caustic injuries with a view to finding clinical and biological risk factors of esophageal strictures secondary to caustic ingestion. Records were retrieved for 58 adults admitted consecutively to our intensive care unit for caustic ingestion. Fifty cases were managed conservatively and therefore retained for analyses. Patients were grouped according to whether they developed strictures or not during the follow-up period. Mucosal damage was assessed by emergency endoscopy. Eleven patients (22%) developed a stricture. At referral, dysphagia, epigastric pain, and hematemesis were associated with secondary stricture (respectively P = 0.047, P = 0.008, P = 0.02). A high Zargar endoscopic grade (above IIa; P = 0.02), the ingestion of strong acids or alkalis (P = 0.006), hyperleukocytosis (P = 0.02), and a low prothrombin ratio (P = 0.002) were associated with a higher risk of developing a stricture. The median delay of stricture diagnosis was 12 (8;16) days after ingestion, with extreme values from 4 to 26 days. Initial symptoms such as dysphagia or hematemesis, early endoscopy showing >IIa grade esophagitis, and certain laboratory results should draw the physician's attention to a high risk of esophageal stricture.

Abstract
Various domestic or industrial chemicals may cause significant upper aerodigestive tract burns. Preventive measures should be up-scaled, especially in the developing world, to reduce the epidemic of accidental victims, largely unsupervised preschool children. External signs do not predict degree of injury. Non-invasive diagnostic screening includes radio-nuclear imaging, but early oesophago-gastroduodenoscopy remains the standard to predict stricture formation from circumferential submucosal scarring. Serial dilation is the mainstay of oesophageal stricture therapy, with oesophageal replacement reserved for severe refractory strictures. Intra-lesional steroid or mitomycin C may decrease the dilatations required for severe strictures, although long-term effects are unknown. Risk of secondary oesophageal carcinoma mandates long-term surveillance.

Abstract
Corrosive injury results from the intake of corrosive-acid-based chemicals. However, this phenomenon is limited to a small number of cases and cannot be extrapolated to the epidemiology of corrosive injuries in actual situations. This study focuses on the annual incidence of corrosive injury and its connection to gender, risk factors, and in-hospital mortality. All patients with corrosive injury (ICD-9 947.0–947.3) were identified using a nationwide inpatient sample from 1996 until 2010. Chi-squared tests and multivariate logistic regression were used to examine risk factors of gender differences and in-hospital mortality of corrosive injury. Young adults comprised the majority of patients (71.2%), and mean age was 44.6 ± 20.9 years. Women showed a higher incidence rate of corrosive injuries, age, suicide, psychiatric disorder, and systemic complications compared with men (p < 0.001). The present study demonstrated that age (OR = 10.93; 95% CI 5.37–22.27), systemic complications (OR = 5.43; 95% CI 4.61–6.41), malignant neoplasms (OR = 2.23; 95% CI 1.37–3.62), gastrointestinal complications (OR = 2.02; 95% CI 1.63–2.51), chronic disease (OR = 1.30; 95% CI 1.08–1.56), and suicide (OR = 1.23; 95% CI 1.05–1.44) were strongly associated with in-hospital mortality. Educational programs may be helpful for reducing the incidence of ingestion of corrosive chemicals.

Abstract
BACKGROUND The ingestion of caustic substances remains an important public health issue worldwide. Children represent 80% of the ingestion injury population globally. Accidental alkaline material accounts for most caustic ingestions. There is no conclusive evidence of tissue damage and stricture protection of a nasogastric-tube with a solid dilator in the literature, therefore it was hypothesized that early intraesophageal tube placement does not cause additional histopathologic damage and prevents strictures. METHODS An exploratory study on experimental caustic esophageal burns in a rabbit model was designed. In the treated group a silicone tube was placed immediately after causing the burns, while the untreated group followed the natural course of the burn. On the twenty-secondday, an esophagectomy was performed on all animals for microscopic (Histopathologic Damage Score and Stenosis Index) and macroscopic analysis. RESULTS Forty animals were randomly divided into two groups. The Histopathologic Damage Score was 3.7±1.1 in the treated group versus 3.9±1.2 in the untreated group (p=.9690). The Stenosis Index was 0.6±0.1 in treated rabbits versus 2.3±0.2 in untreated (p<.0001). CONCLUSION The early placement of an intraesophageal tube with solid dilator prevents stenosis formation and does not produce greater tissue damage.

Abstract
Esophagitis is a frequent cause of clinical symptoms and is often an indication for upper endoscopy. Mucosal biopsies are procured for diagnostic purposes and may be used to assess the efficacy of treatment, as in patients with eosinophilic esophagitis. This article outlines salient clinical and pathologic features of diseases that cause esophagitis exclusive of reflux esophagitis.
