Usage of “large‐for‐size” left lateral segment (LLS) liver grafts in children with high graft to recipient weight ratio (GRWR) is controversial due to concerns about increased recipient complications. During the study period, 77 pediatric living donor liver transplantations (LDLTs) with LLS grafts were performed. We compared recipients with GRWR ≥2.5% (GR‐High = 50) vs GRWR <2.5% (GR‐Low = 27). Median age was higher in the GR‐Low group (40 vs 8 months, P> .0001). Graft (GR‐High: 98%, 98%, 98% vs GR‐Low: 96%, 93%, 93%) and patient (GR‐High: 98%, 98%, 98% vs GR‐Low: 100%, 96%, 96%) survival at 1, 3, and 5 years was similar between groups (P = NS). Overall complications were also similar (34% vs 30%; P = .8). Hepatic artery and portal vein thrombosis following transplantation was not different (P = NS). Delayed abdominal fascia closure was more common in GR‐High patients (17 vs 1; P = .002). Subgroup analysis comparing recipients with GRWR ≥4% (GR‐XL = 20) to GRWR <2.5% (GRWR‐Low = 27) revealed that delayed abdominal fascia closure was more common in the GR‐XL group, but postoperative complications and graft and patient survival were similar. We conclude that pediatric LDLT with large‐for‐size LLS grafts is associated with excellent clinical outcomes. There is an increased need for delayed abdominal closure with no compromise of long‐term outcomes. The use of high GRWR expands the donor pool and improves timely access to the benefits of transplantation without extra risks. |
