Gallstone ileus as a cause of upper intestinal obstruction
Emergency Room of the Hospital das Clinicas, College ofMedicille, University of Siio Paulo (USP), Trauma Surgery Discipline -Siio Paulo, BrazilGallstone ileus, a mechanical intestinal obstruction caused by the passage of a gallstone into the intestinal lumen through a fistula, although not common, deserves to more carefully studied due to its morbidity and mortality. Its incidence among older-age groups explains its association with chronic and degenerative diseases, which increase the complexity of the treatment choice. The need and appropriateness of a surgical approach to a cholecystenteric fistula to solve the obstructive emergency, in a one or two stage procedure, has been discussed in the literature. It has also been reported that gallstone ileus is an uncommon cause of upper intestinal obstruction. Intestinal obstruction is seen more frequently after a gallstone impacts at the ileocecal valve. The authors report a case of gallstone ileus as a cause of upper intestinal obstruction and discuss its diagnosis and treatment.
Avaliação de eficácia da laparoscopia, associada à análise bacteriológica do líquido intraperitoneal pela coloração de Gram., no diagnóstico de lesões intra-abdominais provocadas em cães com arma de ar comprimido. A alta incidência de óbitos como resultado de ferimentos por arma de fogo tem contribuído para implantação de novas técnicas diagnósticas. O uso crescente de laparoscopia diagnóstica em urgências torna necessário aprimorar qualidade e fidedignidade dos resultados obtidos. Este experimento avalia acurácia, sensibilidade e especificidade da laparoscopia, incluindo 20 cães submetidos a trauma abdominal, com disparo do tipo encostado, e cinco cães como grupo de controle. Na laparoscopia, foram feitos inventário sistemático da cavidade abdominal, conferido por laparotomia, e coleta de líquido intraperitoneal para análise bacteriológica. A laparoscopia apresentou acurácia de 88,29%, sensibilidade de 88,29% e especificidade de 100%. O valor preditivo positivo da coloração de Gram foi 100%. Concluiu-se que a laparoscopia é eficaz no diagnóstico de lesões intra-abdominais provocadas por arma de ar comprimido, em cães hemodinamicamente estáveis. Mas, algumas lesões, evidenciadas na laparotomia, passaram despercebidas na laparoscopia. Realização concomitante de análise bacteriológica pela coloração de Gram pode aumentar a eficácia e diminuir a possibilidade de erros no diagnóstico de lesões. Laparoscopia associada à análise bacteriológica possibilita melhores resultados com mínimo dano ao paciente
Mechanic intestinal obstruction, caused by the passage of biliary calculus from vesicle to intestine, through fistulization, although not frequent, deserve study due to the morbi-mortality rates. Incidence in elder people explains the association with chronic degenerative diseases, increasing complexity in terms of therapy decision. Literature discusses the need and opportunity for the one or two-phase surgical attack of the cholecyst-enteric fistule, in front of the resolution on the obstructive urgency and makes reference to Gallstone Ileus as an exception for strong intestinal obstruction. The more frequent intestinal obstruction observed is when it occurs a Gallstone Ileus impacting in terms of ileocecal valve. The authors submit a Gallstone Ileus manifestation as causing strong intestinal obstruction, discussing aspects regarding diagnostic and treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
