Abstract

Consultations of Gastroenterology practitioners are frequently sought for many complex issues relating to acute and chronic liver disease. Many of the disease entities are uncommon and complicated in scope. Liver disease may occur in the setting of other chronic medical conditions and involve other organ systems, with recommendations for diagnostic strategies and therapeutic approaches somewhat challenging. Serious consequences are often the rule with misdiagnosed or inadequately treated liver disease. Dr. Flamm has provided a framework for approaching consultation for common liver-related problems for the gastroenterology practitioner. Articles are devoted to the following topics: Common Findings and Interpretation for the Clinician; Genetic Testing in Liver Disease: What to Order and When; Acute Liver Failure; Liver Disease in Oncology Patients; Primary Sclerosing Cholangitis: What the Gastroenterologist/Hepatologist Needs to Know; An Update on the Treatment and Follow up of Patients with PBC; Wilson’s Disease: Diagnosis, Treatment, and Follow Up; Follow Up of the Post-Liver Transplantation Patient: A Primer for the Practicing Gastroenterologist; Liver Disease in Patients on Total Parenteral Nutrition; Treatment Strategies in NAFLD: What’s Coming; Resistance Testing in Chronic HCV; and HCV genotype 3: Treatment Approach and Natural History.
