Unusual Presentation of Caustic Ingestion and its Surgical Treatment: A Case Report

Treatment and reconstruction of oral scar contracture, is always a challenging procedure to restore structure and functions of the oral cavity. We present a case of a patient with limited mouth opening who sustained extensive oral scar contracture with complete adhesion of tongue to floor of mouth following ingestion of caustic soda without his knowledge 4 years back. We performed a surgical release of the scar contractures from buccal mucosa on both sides, along with a release of the tongue from the floor of the mouth, followed by reconstruction of all sites using split skin grafts. Adequate mouth opening and tongue movement was achieved. There was a follow up period of 1 month with excellent mouth opening and tongue function

Consumo alimentar de crianças e adolescentes com disfagia decorrente de estenose de esôfago: avaliação com base na pirâmide alimentar brasileira Food consumption by children and adolescent with dysphagia due to esophageal stricture: assessment based on the Brazilian food guide pyramid

OBJETIVO: Avaliar o consumo alimentar de pacientes com disfagia decorrente de estenose de esôfago, comparando a dieta de consistência líquida com a dieta de consistência pastosa e sólida, com base na Pirâmide Alimentar Brasileira. MÉTODOS: Estudo de corte transversal, no qual foram incluídos consecutivamente 31 pacientes com estenose esofágica, sendo 18 (58,0%) cáustica, 7 (22,6%) pós-cirúrgica, 3 (9,7%) péptica e 3 (9,7%) sem causa definida. Empregou-se o recordatório de 24 horas; os alimentos foram transformados em porções em função dos oito grupos de alimentos, conforme recomendado por Philippi. Utilizou-se o teste Kruskal-Wallis e Exato de Fisher, fixando em 5% o nível de rejeição da hipótese de nulidade. RESULTADOS: A idade variou entre 15 e 176 meses (mediana, 56 meses), sendo 28 crianças e três adolescentes, e 18 do sexo masculino. Vinte e nove pacientes (93,5%) apresentavam disfagia, sendo grave em 34,4% (10/29), moderada em 41,3% (12/29), e leve em 24,1% (7/29). O consumo mediano de porções de cereais, leguminosas, e óleos e gorduras foi menor no grupo com dieta líquida (p<0,005), o qual também apresentou maior proporção de pacientes cujo consumo foi abaixo do proposto pela pirâmide alimentar quando comparado ao grupo com dieta pastosa e sólida, com diferença estatisticamente significante (p<0,05). CONCLUSÃO: O suporte nutricional é de extrema importância no tratamento de pacientes com estenose esofágica, principalmente na disfagia grave, cuja dieta deve ser adaptada à consistência líquida, devido ao risco nutricional que se atribui à limitada ingestão alimentar, e para que o tratamento dietético seja precocemente instituído.<br>OBJECTIVE: This study assessed food intake by patients with dysphagia due to esophageal stricture and compared liquid, soft and solid diets based on the Brazilian Food guide pyramid. METHODS: This cross-sectional study consecutively included 31 patients with esophageal stricture, of which 18 (58.0%) were caustic, 7 (22.6%) were postoperative, 3 (9.7%) were peptic and 3 (9.7%) were of unknown etiology. The 24-hour dietary recall was used and the foods were converted into servings according to the eight food groups, as recommended by Philippi. The Kruskal-Wallis and Fisher's Exact Test were used and the significance level was set at 5%. RESULTS: The ages of the patients varied from 15 to 176 months (median: 56 months). There were 28 children and 3 adolescents, of which 28 were males. Twenty-nine patients (93.5%) presented dysphagia, of which 34.4% (10/29) were severe, 41.3% (12/29) were moderate and 24.1% (7/29) were mild. The median intake of grain, legume and fat servings was smaller in the liquid diet group (p<0.005). This group also had a significantly greater proportion of patients whose intakes were below those recommended by the food pyramid (p<0.05). CONCLUSION: Nutritional support is extremely important in the treatment of patients with esophageal stricture, especially those with severe dysphagia. These patients need a liquid diet because of the nutritional risk associated with inadequate food intake, which also allows early introduction of the dietary treatment

Avaliações morfológica e funcional do esôfago distal de coelhos submetidos a infusão esofágica com soda cáustica

A ingestão de substâncias cáusticas constitui importante situação de emergência, tendo em vista a gravidade de suas seqüelas. OBJETIVO: Estudar as alterações morfológicas e funcionais do esôfago de coelhos submetidos à infusão esofágica com soda cáustica (NaOH). MÉTODOS: 88 coelhos foram divididos em 4 grupos: G1 (n=22) foi submetido à infusão esofágica com água destilada; G2, G3 e G4 foram submetidos a infusão esofágica com NaOH a 2%, 4% e 6%, respectivamente. Alterações morfológicas foram estudadas em 12 animais de cada grupo e as alterações manométricas, nos 10 animais restantes. Foram feitas análises do esfíncter inferior do esôfago (EIE), número e amplitude das contrações no terço distal do esôfago. Estes estudos foram realizados antes (momento 1 - M1) e aos 30 minutos, 6 horas e 24 horas após a infusão esofágica (momentos M2, M3 e M4, respectivamente). RESULTADOS: Avaliação macroscópica: G1 - sem alterações; G2 - edema, hiperemia e descamação; G3 - aumento do calibre do esôfago, úlceras, descamação da mucosa; G4 - lesões semelhantes as do G3, porém mais intensas, áreas de extensa hemorragia. Avaliação funcional: a pressão no EIE foi mais elevada em M2 no grupo 2; o número das contrações no terço distal do esôfago foi menor em G3 e G4, e a amplitude das contrações foi menor em G4. CONCLUSÕES: 1) a infusão esofágica com NaOH constitui excelente modelo experimental de esofagite cáustica no coelho; 2) a infusão esofágica com NaOH causa lesões na parede do esôfago, com gravidade proporcional a concentração da solução; 3) a infusão causou espasmo do EIE em M2 e redução do número e amplitude das contrações no terço distal do esôfago.The ingestion of caustic substances is an important emergency situation, because of its serious consequences. PURPOSE: To study morphological and functional alterations of the esophagus in rabbits submitted to esophageal infusion of caustic soda (NaOH). METHODS: The 88 rabbits studied were divided into 4 groups: G1 (n=22) were submitted to esophageal infusion with distilled water. G2, G3, and G4 were submitted to esophageal infusion of 2%, 4% and 6% NaOH respectively. Morphological alterations were studied in 12 animals from each group and manometric alterations in the remaining 10. An analysis was made of lower esophageal sphincter (LES) pressure, number and amplitude of contractions in the distal third of the esophagus. These studies were performed before (moment M1) and at 30 minutes, 6 hours, and 24 hours after (moments M2, M3, and M4, respectively) esophageal infusion. RESULTS: Morphological evaluation: G1 - no alterations; G2 - edema, hyperemia, and ecdysis; G3 - enlarged calibre of esophagus, ulcers, ecdysis of mucosa; G4 - lesions similar to G3, but more intense, areas of extensive hemorrhage at M3 and M4. Functional evaluation: LES was higher at M2; the number of distal third lower esophageal contractions in G3, and G4 was lower; and the contraction amplitude was lower in G4. CONCLUSIONS: 1) Esophageal infusion with caustic soda in rabbits is a good experimental model for studying caustic esophagites. 2) Esophageal infusion with NaOH caused lesions in the esophageal wall, with gravity proportional to solution concentration; 3) Infusion caused LES spasm at M2, and reduced both contraction number and amplitude in the distal third of the esophagus.State University of São Paulo School of Medicine Department of Surgery and OrthopedySchool of Medicine of Marilia Department of SurgeryUNESP Institute of Biosciences Department of StatisticsUNESP Institute of Biosciences Department of Statistic
