Factors contributing to pain following surgery are poorly understood with previous research largely focused on adults. With approximately 6 million children undergoing surgery each year8, there is a need to study pediatric persistent postsurgical pain. The present study includes patients with adolescent idiopathic scoliosis undergoing spinal fusion surgery enrolled in a prospective, multi-centered registry examining post-surgical outcomes. The Scoliosis Research Society Questionnaire- Version 30, which includes pain, activity, mental health, and self-image subscales, was administered to 190 patients prior to surgery and at 1 and 2 years post-surgery. A subset (n=77) completed 5-year post-surgery data. Pain prevalence at each time point and longitudinal trajectories of pain outcomes derived from SAS PROC TRAJ were examined using ANOVAs and post-hoc pairwise analyses across groups. Thirty-five percent of patients reported pain in the moderate-severe range prior to surgery. One year postoperative, 11% reported pain in this range while 15% reported pain at two years post-surgery. At five years post-surgery, 15% of patients reported pain in the moderate to severe range. Among the five empirically-derived pain trajectories, there were significant differences on self-image, mental health, and age. Identifying predictors of poor long-term outcomes in children with postsurgical pain may prevent the development of chronic pain into adulthood.

This study analyzed how features of a liver graft and the technique of biliary reconstruction interact to affect biliary complications in pediatric liver transplantation. A retrospective analysis was performed of data collected from 2001 to 2011 in a single high-volume North American pediatric transplant center. The study cohort comprised 173 pediatric recipients, 75 living donor (LD) and 98 deceased donor (DD) recipients. The median follow-up was 70 months. Twenty-nine (16.7%) patients suffered a biliary complication. The majority of leaks (9/12, 75.0%) and the majority of strictures (18/22, 81.8%) were anastomotic. There was no difference in the rate of biliary complications associated with DD (18.4%) and LD (14.7%) grafts (P 5 0.55). Roux-en-Y (RY) reconstruction was associated with a significantly lower rate of biliary complications compared to duct-to-duct reconstruction (13.3% versus 28.2%, respectively; P 5 0.048). RY anastomosis was the only significant factor protecting from biliary complications in our population (hazard ratio, 0.30; 95% confidence interval, 0.1-0.85). The leaks were managed primarily by relaparotomy (10/12, 83.3%), and the majority of strictures were managed by percutaneous biliary intervention (14/22, 63.6%). Patients suffering biliary complications had inferior graft survival (P 5 0.04) at 1, 5, and 10 years compared to patients without biliary complications. Our analysis demonstrates a lower incidence of biliary complications with RY biliary reconstruction, and patients with biliary complications have decreased graft survival.

Treatment by IRP, coupled with recent advances in the medical management of intestinal failure, is associated with improved survival and outcome of patients waiting for IT, and may lead to overall reduction in the number of IT in the future.

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.

Renal impairment is frequently compromised in patients with end-stage liver disease and is associated with increased long-term mortality post-LT. In contrast to CNI, basiliximab is an immunosuppressive agent with minimal nephrotoxic potential. This study reviews the experience of a single pediatric liver transplant center's renal-sparing approach with the use of basiliximab and MMF to compensate for delayed entry of CNI in children with renal impairment at the time of organ availability. There were no differences in renal function between pediatric patients with and without pre-LT renal impairment within the first year (cGFR: 135 mL/min/1.73 m2 vs. 144 mL/min/1.73 m2 ; p = 0.56) or at 5-8 yr following LT, (129 mL/min/1.73 m2 vs. 130 mL/min/1.73 m2 ; p = 0.97). In addition, there was no difference in ACR rates (50% vs. 43%, p = 0.62) between patients in the basiliximab group and those patients receiving standard CNI and steroid strategies. The utilization of a renal-sparing approach with basiliximab alongside delayed entry and lower early target trough levels of CNI in children with renal impairment at the time of LT is safe and maintains excellent long-term kidney function.

Physical Activity (PA) plays an important role in the physical and psychosocial health of children and is beneficial in the treatment and prevention of comorbidities associated with transplantation. Despite this, PA participation in pediatric liver transplant recipients remains low compared to healthy peers. This qualitative-focused mixed-methods study explored the PA experiences and parental perception of these experiences, including perceived facilitators and barriers to PA in children post-liver transplant. Eighteen participants (9 children [median age 10.8 years] and 9 parents) took part in semi-structured interviews and completed the PedsQL Multidimensional Fatigue Scale and PAQ. Most children reported they were physically active (PAQ median 3.08 [IQR] 2.60-3.51), participating in PA for its enjoyment, regardless of their level of motor proficiency. Levels of fatigue (median 65.28 [IQR] 56.25-90.97) were higher than healthy norms and impacted PA participation in some children. Children and parents perceived PA as central to post-transplant recovery and valued its social and mental health benefits; however, parents struggled with ongoing uncertainty and perceived physical vulnerability of their child. This study indicates the need for continuing PA support and education and provides valuable information for family-centered interventions to increase PA and improve health outcomes in children post-transplant.
