title: Non-cirrhotic liver tolerance to intermittent inflow occlusion during laparoscopic liver resection.
abstract: While inflow occlusion techniques are accepted methods to reduce bleeding during open liver surgery, their use in laparoscopic liver resections are limited by possible effects of pneumoperitoneum on ischemia-reperfusion liver damage. This retrospective study was designed to investigate the impact of intermittent pedicle clamping (IPC) on patients with normal liver undergoing minor laparoscopic liver resections. Three matched groups of patients were retrospectively selected from our in-house database: 11 patients who underwent robot-assisted liver resection with IPC, and 16 and 11 patients who underwent robot-assisted liver resection without IPC and open liver resection with IPC, respectively. The primary end point was to assess differences in postoperative serum alanine, aspartate aminotransferase (ALT and AST) and bilirubin levels. The curves of serum AST, ALT and bilirubin levels in a span of time of five postoperative days were not significantly different between the three groups. IPC has no relevant effects on ischemia-reperfusion liver damage even in the presence of pneumoperitoneum.
