Enfermedad veno-oclusiva hepática, colitis ulcerosa idiopática y trombosis portal: comunicación de un caso clínico / Hepatic veno-occlusive disease, idiopathic ulcerative colitis and portal thrombosis. Report of one case

We report a previously healthy 29 years old man, presenting with a sudden episode of abdominal pain, mild jaundice, hepatomegaly and ascites. Magnetic resonance imaging study and liver biopsy were compatible with veno-occlusive disease. Incidentally, an ulcerative colitis and portal vein thrombosis were diagnosed. Anticoagulant treatment was started, with good clinical and radiological response. Veno-occlusive disease of the liver must be suspected In cases of liver failure and ascites associated to procoagulant conditions.

Daño hepático por fármacos: características clínicas e histológicas en 33 casos / Drug induced liver disease: clinical and pathological patterns in 33 cases

BACKGROUND: Drug induced liver disease (DILD) is common and of difficult diagnosis. AIM: To report the clinical, laboratory and pathological findings in 33 patients with DILD. PATIENTS AND METHODS: We revised 1,164 liver biopsies and 57 were selected as suspicious of DILD. In these, the scale proposed by Maria et al was applied to assess the possibility of hepatotoxicity reactions and 33 were selected. RESULTS: The 33 cases had a mean age of 48 +/- 18 years and 14 were male. Forty eight medications were involved, with an average of 1.4 drugs per patient. The main drugs were antimicrobials, antineoplastics-immunosuppressives and non-steroidal antiinflammatory drugs. The clinical presentations in order of frequency were cholestasis, hepatitis, asymptomatic, fulminant hepatitis and cirrhosis. The laboratory alterations observed in cases with hepatitis were 20 fold transaminase and bilirubin elevation. In cholestasis, moderate elevations of alkaline phosphatases and gamma glytamyl transferase were observed. Pathology showed hepatocellular damage, cholestasis and mixed damage, but also submassive necrosis and cirrhosis in one case. CONCLUSIONS: The present study confirms that DILD is frequently unpredictable and that it can cause a wide variety of clinical and pathological presentations, that can even evolve to chronicity.

Progresión de metaplasia intestinal a adenocarcinoma en esófago de Barrett: utilidad de la vigilancia endoscópica / Progression from intestinal metaplasia to adenocarcinoma in Barrett s esophagus: usefulness of endoscopic surveillance

BACKGROUND: The potential progression from intestinal metaplasia to low grade dysplasia, to high grade dysplasia and to adenocarcinoma represents a well recognized sequence in patients with Barrett's esophagus (BE). The time required for this transformation is not well known. AIM: To report the results of a 10 years follow up of patients with BE. MATERIAL AND METHODS: Between 1989 and 2000 we followed 402 patients with BE. RESULTS: Sixty six subjects (16.2 per cent) presented low grade dysplasia at the time of diagnosis and 10 patients (2 women/8 men) developed adenocarcinoma during the follow-up period. Four out of these 10 patients were operated because of gastro-esophageal reflux disease, but after 3-5 years, reflux symptoms recurred. The other 6 patients rejected surgery and were on Omeprazole with good symptomatic results. Two patients had a short BE (< 3 cm), seven cases had a classic BE (3-10 cm) and one patient had an extensive > 10 cm BE. The mean time elapsed from intestinal metaplasia to low grade dysplasia was 9 months, to high grade dysplasia 56 months and to adenocarcinoma 82 months. From low grade dysplasia to early cancer it was 18 months, from high grade dysplasia to early cancer 14 months and from high grade dysplasia to advanced transmural cancer 14 months. All patients were subjected to esophagectomy. Five patients detected as State I are alive without any evidence of recurrence after 36 to 130 months after surgery. Five patients with advanced transmural carcinoma subjected to radical esophagectomy died because of progression of the malignancy between 3 and 24 months after surgery. CONCLUSIONS: Progression to adenocarcinoma may occur even in absence of reflux symptoms while on acid suppression therapy. Detection at early stage intestinal metaplasia in the esophagus offers a high chance of cure after surgical resection.

Colecistectomía laparoscópica y clásica en pacientes con cirrosis hepática / Laparoscopic and classic cholecystectomy in patients with liver cirrhosis

BACKGROUND: The prevalence of gallstones is increased in patients with cirrhosis. However the presence of cirrhosis has been generally considered a relative contraindication to cholecystectomy. AIM: To investigate the complications and the outcomes of laparoscopic and open cholecystectomy in patients with cirrhosis. PATIENTS AND METHODS: Sixty seven patients with gallstones with well-documented cirrhosis undergoing cholecystectomy (laparoscopic cholecystectomy (LC) in 35 and open cholecystectomy (OC) in 32), were studied. The mean age was 57.7 + 10.3 years for LC and 58.9 + 11.6 years for OC. In the LC group, 26 were classified as Child-Pugh class A, 8 as Child's B class and 1 as Child's class C. In the OC group, 12 were classified as Child's class A, 15 as Child's B and 5 as Child's C. RESULTS: Complications occurred in 4 of 35 (12.3 per cent) LC patients (1 patients was Child A and 3 were B). In the OC group 14 of 32 patients had complications (4 Child A, 7 B and 3 C, 43.7 per cent p < 0.05 as compared with LC group). Three patients in the OC group died (9.4 per cent). Mean hospital stay was 2.8 + 1.9 and 13 + 12 days in LC and OC patients, respectively (p < 0.05). CONCLUSIONS: LC has a lower rate of complications than OC and is a reasonable option for Child's class A and B patients with cirrhosis and gallstones.
