OBJECTIVE: The aim of this study was to evaluate in our healthcare area the clinical, ultrasonographic, and evolutionary features of patients with chronic liver disease and angioma-like liver lesions on ultrasonography. MATERIALS AND METHODS: We conducted a retrospective study amongst patients seen at the Ultrasonography Unit, Gastroenterology Department between January 2000 and June 2004. Included in the study were patients that presented with clinical and/or laboratory complaints consistent with chronic liver disease of any etiology, and those in which abdominal ultrasounds revealed the existence of at least one angioma-like liver lesion. All relevant epidemiological, clinical, ultrasonographic, and evolutionary data were carefully collected and recorded. RESULTS: In the course of our study, 58 patients were diagnosed with chronic liver disease and angioma-like liver lesions, of which 13 showed clinical, laboratory, ultrasonographic, and/or histological signs of liver cirrhosis. In 50% of patients these lesions were less than 10 mm in diameter, and in most cases were located in the right hepatic lobe. During an average follow-up period of 35 months (6-168 months) we verified that, in two patients, these lesions, initially interpreted as angiomas were in fact malignancies (one hepatocellular carcinoma and one metastatic adenocarcinoma of the gallbladder). In both cases, the patients were cirrhotic. Thus, our study revealed that 15% of lesions found in cirrhotic patients initially interpreted as angiomas were actually malignant. CONCLUSIONS: Our study revealed that, in patients with chronic liver disease, particularly in cirrhotic patients, a considerable percentage of ultrasonographic lesions originally interpreted as angiomas are in fact malignant tumors.

El tratamiento de la hepatitis crónica por virus C ha experimentado un gran avance en los pocos años que han transcurrido desde el descubrimiento del genoma de dicho virus en 1989 y desde los primeros resultados obtenidos con el interferón hasta la actualidad, habiéndose multiplicado prácticamente por 5 el porcentaje de respuesta sostenida que conseguimos en estos pacientes con la terapia combinada con interferón pegilado y ribavirina, por lo que ya quedan lejos aquellos resultados que superaban difícilmente el 10 por ciento de respuesta sostenida y que hacían poco atractivo el tratamiento de estos enfermos. En la actualidad las cifras en torno al 60 por ciento de respuesta sostenida, aunque lejos aún de las deseables permiten iniciar los tratamientos con mayor esperanza y estimulan a ser menos reticentes a la hora de indicarlos. No obstante la obtención de fármacos de más cómoda administración. menores efectos secundarios y mayor eficacia especialmente en los grupos más rebeldes a los tratamientos actuales, sigue siendo un objetivo aún lejos de lograrse (AU)

The case of a young female diagnosed with an IgG deficit and hepatic granulomas is presented. After 6 years of follow up the patient remains asymptomatic without treatment and with moderate biochemical cholestasis. The tests performed did not lead to a definitive etiologic diagnosis, therefore, according to a review of the literature, we believe that the granulomatous reactions are related with the hypogammaglobulinemia itself.

The case of a patient ulcerative colitis involving an autoimmune base who was treated with recombinant alpha-2 interferon for concomitantly presenting chronic hepatitis B in the replicative phase is reported. With this therapy unreplicative seroconversion of the disease was achieved without modification of the course of the chronic inflammatory intestinal disease (CIID) during treatment or over the posttreatment follow up period. A brief review of the literature was performed concerning the role of autoimmunity in ulcerative colitis, treatment with alpha-interferon in chronic hepatitis B and the exacerbation of autoimmune phenomena which may lead to interferon treatment. According to the evolution of this case and the review of the literature, the authors conclude that the existence of CIID does not contra-indicate the use of recombinant alpha-2 interferon in patients with chronic viral hepatitis, although special control of the disease should be carried out during the treatment period.

We report a case of solitary rectal ulcer (SRU) in a patient who had been previously diagnosed of granulomatous appendicitis. Both entities were histologically confirmed. The patient is asymptomatic after appendectomy done one and a half years ago, demonstrating the low recurrence rate of granulomatous appendicitis and the silent course of solitary rectal ulcer in many patients. Both entities may be related.

AIM: To communicate the results of two different schedules (cyclic and continuous) of mebendazole therapy for hepatic and intraabdominal hydatid disease. DESIGN: Prospective and randomized. PATIENTS: 26 cases of abdominal hydatid disease. RESULTS: No significant differences were registered between both groups. CONCLUSION: Cyclic mebendazole therapy does not improve the results of continuous treatment in abdominal hydatid disease.

The efficacy of albendazole in hydatid disease is still unclear, because there has been no study that assessed the status of the parasite after treatment. The significance of albendazole-induced echographic changes in the cyst therefore cannot be judged. We did a prospective, controlled, randomised, open study of albendazole in patients with liver hydatid disease, and assessed parasite viability after treatment. 18 patients received no albendazole treatment (controls), 18 received albendazole (10 mg/kg daily) for 1 month (group A), and 19 received the drug for about 3 months (group B). Echography was done before and during treatment; all patients underwent surgery on completion. Parasite (protoscolex viability and development of cysts in mice) and ultrastructure studies were done for all cysts removed. 8 (50%) of cysts in the control group, 13 (72%) in group A, and 16 (94%) in group B were non-viable (p = 0.015). Protoscolex and cyst viability were significantly (p = 0.039 and p = 0.018, respectively) lower in treated patients than in controls. Treatment was also significantly associated with total cyst membrane disintegration. 68% of cysts treated for 3 months showed echographic changes, and only 1 of 20 cysts showing echographic changes during treatment was judged viable. The efficacy of albendazole at a dose of 10 mg/kg daily for 3 months suggests that it is a suitable alternative to surgery in uncomplicated hydatid liver disease, as initial treatment.

A case of solitary gastric hamartomatous polyp, presenting as upper gastrointestinal haemorrhage, is reported. Both the entity itself, and the clinical presentation, are exceptional. The significance of the solitary gastric hamartomatous polyp and implications of its diagnosis are discussed.

We have been interested in demonstrating the usefulness of the reverse endoscopic cholangiopancreatography, a technique already accepted in extrahepatic biliary pathology and the cholangiocarcinoma diagnosis. First of all we reviewed those cases diagnosed as cholangiocarcinoma using the REC and we found that only in 14 (60.9%) of a total of 23 cases the diagnosis was confirmed by surgery, resulting in a false positive ratio of 39.1%. In the second analysis of 22 patients who underwent surgery and whose surgical diagnosis was cholangiocarcinoma, we confirmed a correct presurgery diagnosis by REC in 14 (63.6%) with a false negative ratio of 36.3% which could be reduced to 26.3% after excluding the technically incorrect explorations or those in which only the pancreatic ductus was visualized. We conclude that cholangiocarcinoma diagnosis by REC has a high false positive or negative ratio, thus, treatment, specially non surgical, of a possibly malignant stenosis or obstruction of the bile duct can not only be based on choleangiopatic findings.

Mesenteric venous thrombosis (TVM) is an uncommon entity with a mortality without surgical treatment of virtually 100%. However, recently some cases have been reported of a good evolution with conservative treatment. We present a patient with mesenteric venous thrombosis diagnosed by arteriography who, after refusing surgical intervention, underwent parenteral nutrition and anticoagulant treatment. This case constitutes another proof that mesenteric venous thrombosis is not invariably fatal without surgical treatment.
