Outcome of gastric emptying after liver transplantation. Gastric emptying was scintigraphically measured using a Tc99m-labelled meal and the total half-time of the radioactive marker was used for the analyses. No significant change in gastric emptying half-times was found over time (p = 0.52). Only patients who had completed the scintigraphy at all three time-points were included (n = 26). P < 0.05 was regarded as statistically significant.
