RESUMO
Aportamos el segundo caso de colecistitis aguda litiásica durante el curso de una brucelosis sistémica, según la revisión de la bibliografía mundial. Se describe su semiología clínica y tratamiento. Se resalta la importancia de considerar dicha enfermedad, como concomitante a otras, en zonas geográficas consideradas endémicas para la brucelosis (AU)

BACKGROUND/AIMS: The aim of this study was to evaluate macroscopic and histologic disorders of the colon in rats with portal hypertension. METHODOLOGY: The animals were divided into two groups: 10 rats in the experimental group and 10 controls. Portal hypertension was induced by a partial ligation of the portal vein. We assessed the histologic appearance and macroscopic alterations of the colonic mucosa 12 weeks after the induction of portal hypertension. RESULTS: The macroscopic results showed the presence of the typical signs of portal hypertension, with dilatation and tortuosity of the mesenteric veins and hyperemia of the rectum and colon. Histologic study revealed a marked dilatation in the microcirculation at the level of the ascending colon (20 +/- 2 micra in diameter) and rectum (30 +/- 4), with a tendency to group the lesions. Submucosal edema without inflammatory signs was observed. CONCLUSION: The existence of these lesions in the colon and rectum can be the cause of hemorrhage, as in the gastropathy of portal hypertension and should be considered in cases of undiagnosed hemorrhage in patients with portal hypertension.
