Forty-eight patients with endoscopically proven duodenal ulcer (DU) and Helicobacter pylori infection detected by 14C-urea breath test (BT) were assigned to 5 days of treatment with furazolidone, metronidazole, and amoxicillin in addition to eventual classical anti-ulcer agents if necessary. Clinical evaluation and BT were repeated at 2, 6, and 18 months after therapy to determine H. pylori eradication or reinfection. Endoscopy was also repeated at 6 and 18 months after treatment to detect DU relapse. In 29 (60%) patients H. pylori had been eradicated at 2 months after therapy, and in 19 (40%) infection persisted. After successful eradication, 6 of 29 (20.7%) were reinfected. All 24 patients who were negative at the 18-month evaluation were asymptomatic, free of anti-ulcer drugs, and with healed ulcers, whereas among the 19 positive patients followed up, 11 (57%) continued to be symptomatic and still using anti-ulcer agents (p less than 0.010), and 10 (53%) showed active ulcers at endoscopy (p less than 0.010). H. pylori eradication is clearly followed by long-term remission of DU. Reinfection may be an additional problem in treating DU patients in developing countries.
; Andy Petroianu, TCBC-MG 3 RESUMO: Objetivos: A evolução para fibrose hepática e, posteriormente, para cirrose são fatos bem estabelecidos na colestase extra-hepática prolongada. A despeito dos avanços nos métodos diagnósticos e terapêuticos, essas complicações continuam de difícil solução, principalmente, quando não é possível reverter a causa da colestase. Neste trabalho, procurou-se verificar, em modelo experimental de colestase pela ligadura do ducto hepático comum, se a exclusão do íleo terminal reduziria o desenvolvimento de fibrose hepática. Não houve abordagem direta da causa da colestase, mas atuou-se nos mecanismos de secreção e regulação do fluxo biliar êntero-hepático. Método: Foram utilizadas trinta e cinco ratas Wistar, distribuídas em três grupos: Grupo 1, apenas laparotomia e laparorrafia; Grupo 2, ligadura do ducto hepático comum; Grupo 3, ligadura do ducto hepático comum associada a ressecção do íleo terminal, com reconstrução do trânsito intestinal, por meio de anastomose íleo-cólon ascendente. Após trinta dias, os animais foram mortos e o fígado de cada rata foi retirado, para a análise histológica. Resultados: Os resultados foram submetidos a análise estatística pelo teste de Kuskal-Wallis, com nível de significância de 95 % (p < 0,05). Verificou-se que houve fibrose hepática nos grupos 2 e 3, porém sem cirrose. O Grupo 3 apresentou fibrose menos acentuada que o Grupo 2. Conclusão. Conclui-se que a ressecção do íleo terminal associa-se a menor alteração histológica, no fígado de ratas, decorrente de colestase obstrutiva (Rev. Col. Bras. Cir. 2006; 33(1): 19-23 INTRODUÇÃOA bile é um dos principais veículos de excreção de metabólitos e de drogas do organismo. Entre as substâncias acumuladas no fígado durante a colestase, os ácidos biliares são os mais nocivos, por sua atividade detergente sobre a membrana do hepatócito e de organelas citoplasmáticas. A mais temível complicação da colestase é a fibrose hepática, que pode evoluir para cirrose e para insuficiência hepática 1 . Whitington et al.2 propuseram a derivação biliar parcial externa, como forma de tratamento da colestase e, principalmente, do prurido, secundário à colestase intra-hepática familiar progressiva. A colestase que surge nessa doença caracteriza-se por icterícia colestática crônica, progressiva e hereditária, que evolui para cirrose hepática. O sintoma mais incapacitante é o prurido intenso, decorrente do acúmulo de ácidos biliares. Muitos dos pacientes evoluem para cirrose hepática. Estes autores perceberam a diminuição dos sintomas, notadamente do prurido, e da progressão para a cirrose hepática, após a drenagem biliar externa parcial, por meio de colecistojejunostomia, exteriorizada na pele.Por sua vez, Hollands et al. 3 propuseram, como forma de tratamento dessa mesma afecção, a exclusão dos últi-mos centímetros do íleo terminal, por meio de uma derivação íleo-cólon ascendente, com diminuição da absorção dos áci-dos biliares no ciclo êntero-hepático. Esse procedimento evitava os inconvenientes de uma estomia. Apesar do nú...

ABSTRACT PURPOSE:To investigate the effects of ileal exclusion on hepatic and renal morphology in extra-hepatic cholestasis. METHODS:Twenty four rats were distributed into three groups. Group 1 (control) underwent laparotomy and laparorrhaphy. The animals in groups 2 and 3 underwent hepatic duct ligature and kept in cholestasis for four weeks. After this period, the rats in groups 2 and 3 underwent internal biliary derivation. In Group 3, the last ten centimeters of the terminal ileum were by passed and excluded. Four weeks later, histological and biochemical analysis were performed in all animals of the three groups. RESULTS:In Group 1, no abnormalities regarding hepatic morphology were observed. All animals from groups 2 and 3 presented hepatic fibrosis. No difference was observed between the two groups. No morphological differences in renal histology could be identified among the three groups. There were differences in AST (p<0.05), ALT (p<0.05), direct bilirubin (p<0.05), ƔGT (p<0.05), urea (p<0.05) and creatinine (p<0.05) in Group 3 compared to control. CONCLUSION:The distal ileum exclusion had no influence upon the hepatic and renal morphological alterations, and biochemical liver and kidney tests have worsened.
OBJECTIVE: To verify whether the ileal exclusion interferes with liver and kidney functional changes secondary to extrahepatic cholestasis.METHODS: We studied 24 rats, divided into three groups with eight individuals each: Group 1 (control), Group 2 (ligation of the hepatic duct combined with internal biliary drainage), and Group 3 (bile duct ligation combined with internal biliary drainage and exclusion of the terminal ileum). Animals in Group 1 (control) underwent sham laparotomy. The animals of groups 2 and 3 underwent ligation and section of the hepatic duct and were kept in cholestasis for four weeks. Next, they underwent an internal biliary bypass. In Group 3, besides the biliary-enteric bypass, we associated the exclusion of the last ten centimeters of the terminal ileum and carried out an ileocolic anastomosis. After four weeks of monitoring, blood was collected from all animals of the three groups for liver and kidney biochemical evaluation (albumin, ALT, AST, direct and indirect bilirubin, alkaline phosphatase, cGT, creatinine and urea).RESULTS: there were increased values of ALT, AST, direct bilirubin, cGT, creatinine and urea in rats from Group 3 (p < 0.05).CONCLUSION: ileal exclusion worsened liver and kidney functions in the murine model of extrahepatic cholestasis, being disadvantageous as therapeutic procedure for cholestatic disorders.
