Objective: To summarize our experience in adult-to-infant living donor liver transplantation (A-ILDLT) and to analyze the efficacy and complications of A-ILDLT., Methods: The clinical data, surgical strategies and complications of 28 adult donors and infantile recipients who underwent A-ILDLT from April 2006 to December 2009 were retrospectively analyzed. These 28 patients (14 boys and 14 girls) aged from 80 days to 11.5 months with body weights of 3.08 to 10.3 kg at the time of operation . They suffered from biliary atresia with decompensated cirrhosis. The living donors were 15 mothers, 9 fathers, 3 grandma and 1 elder brother with ABO compatible with the infantile recipients. 27 Donor organs were the left lateral lobe grafts (segment II, III) and 1 graft was segment II. All patients were followed up for 5 to 24 months., Results: These grafts were orthotopically transplanted into the infantile recipients. The average length of stay was 9.3 days for the donor group without any complications. Postoperative immunosuppression included prednisone, Cyclosporin and mycophenolate mofetil (MMF). A total of 24 postoperative complications occurred in 20 recipients, including 5 vascular complications, 4 bleeding, 7 pneumonia, 2 bowel obstruction, 4 intestinal perforation and 3 rejection. Three recipients died of hepatic arterial thrombosis (HAT). The perioperative mortality rate of recipients was 10.7% (3/28) and the survival rate was 89.3% in peroperative period. One died of stricture of hepatic vein and 1 of accidental asphyxia during follow-up term. At present, 23 cases are still alive., Conclusion: A-ILDLT has become an effective method to infants with end-stage liver disease. The postoperative vascular complication is the predominant cause of death.

Objective: To explore the risk factors for hepatoblastoma., Methods: A case-cohort study using Logistic regression multiple variables analysis of medical record data sets was conducted to examine infant and perinatal risk factors for hepatoblastoma., Results: Birth weight less than 1,000 g was associated with a strongly increased risk of hepatoblastoma (odds risk, OR = 26.0, 95% confidence interval, CI: 14.0 to 65.7). After adjustment of birth weight, a moderately increased risk of hepatoblastoma was found for older maternal age ( > 35 years vs. 20 to 34 years: OR = 2.6, 95% CI: 0.9 to 5.9), maternal smoking (OR = 2.9, 95% CI: 1.1 to 4.2) and higher maternal pregnancy body mass index (OR = 3.2, 95% CI: 1.0 to 6.7)., Conclusion: Very low birth weight and maternal characteristics including overweight, smoking are associated with hepatoblastoma risk.

Objective: To review the outcomes of living-related liver transplantation (LRLT) in treating 3 cases of cavernous transformation of portal vein (CTPV) with severe portal hypertension., Methods: Three children (two boys and one girl) were presented to our hospital with recurring esophageal variceal bleeding, decompensating ascites, splenomegaly and refractory anemia. CTPV was confirmed by intravenous computed tomographic portography using a helical computed tomography scanner and 3-dimensional image reconstruction. LRLT were performed in these 3 patients from July 2006 to January 2007. The evaluation of the outcomes was made by referring to their clinical features and laboratory and imaging examination findings., Results: Although one patient died from early graft thrombosis, the other two patients showed excellent prognoses. They lived and stayed well during a follow-up period of 12-14 months. Following the transplantations, there had been no esophageal variceal hemorrhage, the ascites disappeared and the portal hypertension vanished. Their hemoglobin, blood platelets count, and serum albumin reached normal values., Conclusion: LRLT is an effective procedure in treating CTPV with severe portal hypertension. The reconstruction of the portal vein is the difficult part of the LRLT procedure.
