[Hemoperitoneum secondary to acute cholecystitis in kidney transplant]

We present two cases of acute cholecystitis occurring more than two years after renal transplantation. The course of the acute event was complicated by the presence of hemobilia in one of the patients and severe hemoperitoneum in both patients. We comment the possible etiologic factors, the high efficiency of the diagnostic procedures and the importance of prompt cholecystectomy as the best treatment method.
