Delayed sequential abdominal wall closure in pediatric liver transplantation to overcome “large for size” scenarios

Background Primary abdominal wall closure after pediatric liver transplantation (PLT) is neither always possible nor advisable, given the graft‐recipient size discrepancy and its potential large‐for‐size scenario. Our objective was to report the experience accumulated with delayed sequential closure (DSC) guided by Doppler ultrasound control. Methods Retrospective analysis of DSC performed from 2013 to March 2020. Results Twenty‐seven DSC (26.5%) were identified out of 102 PLT. Transplant indications and type of grafts were similar among both groups. In patients with DSC, mean weight and GRWR were 9.4 ± 5.5 kg (3.1–26 kg) and 4.7 ± 2.4 (1.9–9.7), significantly lower and higher than the primary closure cohort, respectively. The median time to achieve definitive closure was 6 days (range 3–23 days), and the median number of procedures was 4 (range 2–9). Patients with DSC had longer overall PICU (22.5 ± 16.9 vs. 9.1 ± 9.7 days, p
