[A rare case of gerniation and incarceration of the gallbladder]

The authors report a rare case of herniation and incarceration of the gallbladder at the site of abdominal drainage tube deployment in a patient undergoing treatment for aortic valve disease. An incarcerated postoperative ventral hernia was confirmed by contrast-enhanced CT of the abdomen. Emergency surgery was not indicated due to spontaneous reduction, short duration of incarceration and no peritoneal signs. This case reminds us the possibility of ventral hernias, containing the gallbladder, at the site of abdominal drainage tube deployment. According to the literature, untimely diagnosis of this event can result fatal consequences.
