[Spiegel's hernia: apropos of 7 cases]. / Hernia de Spiegel: a propósito de siete casos.

The authors present their experience with Spiegel's hernia and a series of seven cases, three of which debuted as intestinal occlusion. On four occasions the hernial content was appreciated, only one of which required resection. The diagnostic procedures most commonly used in this pathology are noted and it is concluded that sonography offers high resolution images and effectiveness in the differential diagnosis. In all the cases the hernia was located below the aponeurosis of the major oblique muscle. Herniorrhaphy was performed in every case, and there was no morbidity, mortality or recurrence of the hernia.

[Extrahepatic biloma secondary to choledocholithiasis]. / Biloma extrahepático secundario a coledocolitiasis.

We present a case of extrahepatic biloma in a patient who was an emergency admission to the hospital and had a clinical pattern of obstructive jaundice secondary to choledocholithiasis. The diagnosis was made by echography and needle aspiration (PAAF). Due to the unfavorable evolution of the patient in the 48 hours after admission, she underwent surgery, which confirmed the diagnosis. Cholecystectomy was performed, with removal of the choledochal gallstone and side-to-side choledochoduodenostomy, and the postoperative evolution was satisfactory. We review the pathophysiologic characteristics of this entity and its etiology, symptomatology, diagnosis and treatment.
