Increased AFP levels in patients with hepatocellular carcinoma are mainly related to tumor size and in a lesser degree, to AST levels. Abnormal and/or diagnostic AFP levels will be observed in a reduced proportion of patients with small HCC (less than 5 cm). Therefore, AFP measurement is of little value in the early detection of HCC.
BACKGROUND/AIMS: In 20-50% of patients bleeding from esophageal varices, conservative procedures fail to obtain hemostasis and prevent early recurrence. METHODOLOGY: We retrospectively analyzed the efficacy and safety of endoscopic sclerotherapy in 66 cirrhotic patients with high surgical risk and persistence or recurrence of variceal bleeding in spite of adequate medical treatment (somatostatin and/or balloon tamponade). RESULTS: Emergency sclerosis controlled bleeding in 46 out of 66 patients (70%). The remaining 20 patients underwent additional procedures to arrest the hemorrhage, and 6 died because of massive bleeding. Early rebleeding occurred in 5 patients (10%). The mortality within 2 days, 1 week, and 6 weeks was 9%, 17% and 32%, respectively. Death was attributed to hemorrhage in 9 cases. Sclerotherapy was associated with complications in 9 patients (14%). CONCLUSION: These results suggest that emergency sclerotherapy is a safe and effective procedure in cirrhotic patients with high surgical risk and persistence or recurrence of bleeding after conservative hemostatic procedures.
