Background: Children frequently undergo routine Doppler‐ultrasound (DUS) after liver transplantation (LT) for which they are fasted, but this may cause hunger and discomfort. Objective: To determine if DUS measurements, with focus on the portal vein (PV), are affected by prandial changes, and if this affects distress and feasibility of the DUS. Materials and Methods: Children were prospectively included to undergo a pre‐ and postprandial DUS on the same day at 6 months after LT. Pre‐ and anastomotic PV peak systolic velocity (PSV), and hepatic artery and hepatic vein DUS measurements were obtained. Pre‐ and postprandial measurements, and relative postprandial change of PV velocity ratio (VR) compared to PV anastomotic PSV, were compared using paired‐sample t‐tests and intraclass correlation coefficients (ICC). Obscuration by bowel gas, difficulty of DUS, and impact of fasting were assessed using 5‐point rating scales. Results: Twenty‐eight children (median age 3.5 years, IQR 1.6–10.8) were included; four were subsequently excluded because they were not fasted (N = 2) or withdrew consent for the second DUS (N = 2). Measurements between pre‐ and postprandial DUS, and relative postprandial change of VR compared to PV anastomotic PSV, were not significantly different (p >.05). Test consistency was good (ICC = 0.69, 95% CI = 0.29–0.67) for PV anastomotic PSV, and excellent (95% CI = 0.61–0.93) for PV VR. Obscuration by bowel gas or ease of DUS did not change after eating (p >.05). The majority (16/28, 57.2%) found fasting difficult, and several (13/28, 46.4%) got upset when fasted. Conclusion: Children with an LT do not need to be fasted for routine DUS, which may decrease the burden of the examination. [ABSTRACT FROM AUTHOR] |
