ABSTRACT

PURPOSE: To evaluate the effects of sucralfate on tissue content of neutral and acids mucins in rats with diversion colitis. METHODS: Thirty-six rats were submitted to a proximal right colostomy and a distal mucous fistula. They were divided into two groups according to sacrifice to be performed two or four weeks after intervention. Each group was divided into three subgroups according daily application of enemas containing saline, sucralfate at 1.0 g/kg/day or 2.0 g/kg/day. Colitis was diagnosed by histological analysis and neutral and acid mucins by Periodic Acid Schiff and Alcian Blue techniques, respectively. The contents of mucins were quantified by computer-assisted image analysis. Student's t paired and ANOVA test were used to compare the contents of both types of mucins among groups, and to verify the variance with time, establishing level of signification of 5% for both (p<0.05). RESULTS: Enemas containing sucralfate improves the inflammation and increases the tissue contents of neutral and acid mucins. The content of neutral mucins does not change with the time or concentration of sucralfate used, while acid mucins increases with concentration and time of intervention. CONCLUSIONS: Sucralfate enemas improve the inflammatory process and increase the tissue content of neutral and acid mucins in colon without fecal stream. .

ABSTRACT

Diversion colitis (DC) is an inflammatory disease that develops in segments with fecal diversion. Sucralfate (SCF) complex, which consists of sucrose octasulfate and polyaluminum hydroxide, has been demonstrated to be effective in the treatment of different forms of colitis. However, until now, the effects of SCF have not been evaluated in DC. OBJECTIVE: to evaluate whether the use of enemas containing SFC improves histological findings in experimental DC. METHODS: Thirty-six rats underwent right colon bypass procedure through the creation of a proximal colostomy and a distal mucous fistula. The animals were divided into two groups according to the euthanization procedure to be performed two to four weeks after surgery. Each experimental group was divided into three subgroups of six animals, which were submitted to daily application of enemas containing saline solution 0.9% or SCF at concentrations of 1.0 g/kg/day or 2.0 g/kg/day, respectively. The diagnosis of DC in segments with fecal diversion was established by histopathological study considering the following variables: epithelial loss, formation of crypt abscesses, the population of goblet cells, inflammatory infiltrate and presence of fibrosis. For statistical analysis, the nonparametric Mann-Whitney and Kruskal-Wallis tests were used, with a significance level of 5% (p <0.05). RESULTS: It was observed that the daily application of SCF enemas decreased epithelial loss, formation of colon crypt abscesses, inflammatory infiltrate and tissue fibrosis (p <0.05), unrelated to time of intervention. The intervention with SCF preserves the goblet cell population. The effects of the substance on the preservation of colonic epithelium; the decrease in the inflammatory process and subsequent abscess formation in the colon crypts are associated with the concentration used, whereas tissue fibrosis decrease is associated with the concentration and time of intervention. CONCLUSION: Preventive application of SCF enemas reduces the inflammatory process in the colon with fecal diversion. (AU)


A colite de exclusão (CE) é uma doença inflamatória que se desenvolve em segmentos desprovidos de trânsito fecal. O sucralfato (SCF) complexo formado pelo octossulfato de sacarose e hidróxido de polialumínio vem se demonstrando eficaz para o tratamento de diferentes formas de colite, porém, até a presente data, os efeitos do SCF ainda não foram avaliados na CE. OBJETIVO: avaliar se a aplicação de clisteres contendo SFC melhora as alterações histológicas encontradas em modelo experimental de CE. MÉTODOS: trinta e seis ratos foram submetidos à derivação do trânsito no cólon direito pela confecção de colostomia proximal e fístula mucosa distal. Os animais foram divididos em dois grupos experimentais de acordo com o sacrifício ser realizado após duas ou quatro semanas do procedimento cirúrgico. Cada grupo experimental foi dividido em três subgrupos de seis animais segundo terem sidos submetidos à aplicação diária com enemas contendo solução fisiológica a 0,9% ou SCF nas concentrações de 1,0g/kg/dia ou 2,0 g/kg/dia. O diagnóstico de CE nos segmentos sem trânsito foi estabelecido por estudo histopatológico considerando-se as seguintes variáveis: perda epitelial, formação de abscessos nas criptas, população de células caliciformes, infiltrado inflamatório e a presença de fibrose. Para análise estatística adotou-se os testes não paramétricos de Mann-Withney e Kruskal-Wallis estabelecendo-se para ambos, nível de significância de 5% (p < 0,05). RESULTADOS: verificou-se que a aplicação diária de enemas com SCF diminui a perda epitelial, a formação de abscessos nas criptas cólicas, o infiltrado inflamatório e a presença de fibrose tecidual (p < 0,05), não relacionada ao tempo de intervenção. A intervenção com SCF preserva a população de células caliciformes. Os efeitos da substância na preservação do epitélio cólico, na redução do processo inflamatório e consequente formação de abscessos nas criptas cólicas encontram-se relacionado à concentração utilizada, enquanto a redução da fibrose tecidual a concentração e ao tempo de intervenção. CONCLUSÃO: a aplicação preventiva de enemas com SCF reduz o processo inflamatório em segmentos cólicos desprovidos de transito intestinal. (AU)

ABSTRACT

Primary epiploic appendagitis (PEA) is a seldom reported disease caused by spontaneous torsion of one or more epiploic appendices. The aim of this study is to describe two cases of PEA reviewing the main aspects of the diagnosis and treatment of disease. Case report: Case 1) Male patient, 55 years old, obese, with abdominal right iliac fossa (RIF) pain for two days. Abdominal examination showed pain on palpation in the RIF with rebound tenderness. Abdominal computed tomography identified lobulated lesion in the cecum, measuring 4.5 cm in diameter, which was suggestive of PEA or early neoplasm of the colon wall. The laparoscopic assessment confirmed the diagnosis of PEA and the appendix was removed. The patient had a satisfactory outcome, being discharged on the second postoperative day. Case 2) Female patient, obese, 47 years old, with abdominal pain for six days, with sudden RIF onset. She had pain at palpation with rebound tenderness. Acute diverticulitis was suspected and patient underwent abdominal CT that identified PEA in the sigmoid colon. After expectant management, the patient showed progressive improvement resuming her activities in seven days. PEA is a rarely recalled condition during the investigation of inflammatory acute abdomen which can be easily recognized by modern imaging methods of assessment. (AU)


Apendagite epiplóica primária (AEP) é uma enfermidade raramente descrita, ocasionada pela torção espontânea de um ou mais apêndices epiplóicos. O objetivo deste estudo é descrever dois casos de AEP revisando os principais aspectos do diagnóstico e tratamento da doença. Relato dos Casos: 1º) Homem, 55 anos, obeso com dor abdominal em FID há dois dias. No exame do abdômen apresentava dor à palpação na FID e descompressão brusca presente. A tomografia computadorizada do abdômen identificou lesão expansiva no ceco, lobulada, medindo 4,5 cm de diâmetro, suspeitando-se de AEP ou neoplasia primitiva da parede cólica. Durante a videolaparoscopia confirmou-se o diagnóstico de AEP sendo removido o apêndice comprometido. O doente apresentou evolução satisfatória recebendo alta no segundo dia. 2º) Mulher, obesa, 47 anos, com dor abdominal há seis dias, de início súbito na fossa ilíaca esquerda. Apresentava dor à palpação local com descompressão brusca presente. Com suspeita de diverticulite aguda foi submetida à TC do abdômen que identificou AEP do cólon sigmóide. Após conduta expectante apresentou melhora progressiva retomando suas atividades em sete dias. A AEP é uma enfermidade raramente suspeitada durante a investigação do abdômen agudo inflamatório, que pode ser reconhecida com facilidade pelos modernos exames de imagem. (AU)
