    Surgical techniques for gastroesophageal reflux disease (GERD) have improved in recent years. This viewpoint considers the evidence in favor of surgical therapy as an alternative to medical therapy for GERD. The safety and clinical efficacy of surgery has been demonstrated, particularly in patients with Barrett's esophagus and those with GERD-related respiratory symptoms.

This Review discusses the history of donor liver allocation in the US, the development of the MELD/PELD allocation system, its success so far and its shortcomings, and the need to optimize the donor organ pool.

    Two new types of imaging technology—laser-scanning confocal endoscopy series and contact endoscopy series—could reduce the number of biopsies that need to be taken by enabling an in vivo 'virtual' histological diagnosis. Although it is currently not clear which technology should be adopted, microscopic evaluation of living tissue is now a reality.

    The histologic spectrum of nonalcoholic fatty liver disease extends from isolated hepatic steatosis to steatohepatitis. Its pathogenesis is linked to insulin resistance and underlying metabolic syndrome. This Review discusses the physiologic basis for hepatic lipid homeostasis, its disturbance in insulin resistance and the genesis of nonalcoholic fatty liver and nonalcoholic steatohepatitis.
