[Usefulness of ultrasonography in the complications of hepatic punction. Prospective studies].

We evaluated the usefulness of ultrasonography (US) to detect hepatic puncture complications. We studied 50 patients, 28 males and 22 females became hepatic puncture. The needles that we used were in 40 Tru-cut in two Chiba in one angiocath and in the other remaining two. US were performed one day before the liver puncture and were repeated 24 to 48 h post-puncture. The procedure was blindly on 29, in fourteen guided by US or scintigraphy, and by laparoscopy in seven. Six patients developed complications (12%), two hemobilia; two subcapsular hematoma, one hemoperitoneum and one hematoma of the abdominal wall. The US detected five of the six complications, and four patients had clinical signs. The sensitivity was 88 percent and the specificity 100%. Platelet count impaired was determinant for the complication. US is useful to detect liver puncture complications.

[Ultrasound-guided percutaneous plugged biopsy of the liver in patients with coagulation disorders. Preliminary report].

The histopathological study is very useful to establish a correct diagnosis in hepatic diseases, nevertheless conventional percutaneous liver biopsy is contraindicated in patients with abnormal coagulation. For this reason, some other alternatives have been looked for. The purpose of this study was to evaluate the safety and effectivity of gelfoam plugged liver biopsy, like alternative of the conventional biopsy in patients with impaired coagulation. The procedure was done in fourteen patients with prothrombin time longer than twelve seconds over the control and platelet count until 20,000/mm3. Besides that, we used real time ultrasound to guide the biopsy, in order to improve the safety and effectivity of this technique. All were successful, and there were no serious complications. This technique is a good alternative in patients with liver disease and impaired coagulation, in whom the histological diagnosis is essential.

[Granulomatous hepatitis secondary to ingestion of carbamazepine. Report of a case].

A 51-year-old man with epilepsy received carbamazepine during three weeks. He developed fever, jaundice, dark urine and pale stools. Laboratory data showed hepatocellular injury and cholestasis; six weeks after withdrawal of the drug these abnormalities returned to normal limits. The liver biopsy showed acute cholangitis, bile duct injury, granulomas and eosinophils in the portal areas.

[Rotor's syndrome. Report of a case].

Rotor's syndrome is a rare entity in our Country. We report here a case of this anomaly in a seventeen years old girl with jaundice from birth, normal biliary channels, elevated urinary coproporphyrins and retarded excretion of bromosulphalein with normal histology of the liver. The familiar study showed that the mother, but not the brothers, had a similar defect in excretion of bromosulphalein.

[Diagnostic methods in Helicobacter pylori infection].

Since their description by Marshall and Warren now ten years ago, a lot of tests have emerging in order to detect infection by Helicobacter pylori. These tests are analyzed in this paper. We divided them in invasive, because they need an endoscopy with biopsy and non invasive with no endoscopy. We inform about the sensitivity and specificity of each one. From the invasive test the histology could be a good alternative for the diagnosis. In order to do epidemiological studies serology is good, and to evaluate the therapeutic efficacy we recommended the 14C or 13C-urea breath test.
