Effect of medium chain triglycerides enriched formula on growth of biliary atresia patients after Kasai portoenterostomy

Background and study aims Biliary atresia (BA) is the most common cause of neonatal cholestasis, negatively affecting nutritional status, growth, and development. It is the most frequent paediatric indication for liver transplantation. The Kasai portoenterostomy (KPE) operation is an effective procedure with favourable outcomes when performed before two months of age. The present study aimed to assess the nutritional status of patients with biliary atresia who underwent the Kasai operation and to evaluate the effectiveness of nutritional counselling using medium-chain triglyceride (MCT) formulas and proper supplementation on their nutritional status, growth, and vitamin D levels. Patients and methods This prospective observational study included 36 infants with biliary atresia who underwent Kasai portoenterostomy. All patients underwent clinical assessment, anthropometric evaluation, nutritional counselling, and an evaluation of vitamin D levels. Only compliant patients (22/36) were followed up after 3 and 6 months of nutritional counselling. Results Z-scores for weight, triceps skinfold thickness, and mid-upper arm circumference improved significantly after three months, and the height velocity Z-score improved after six months of nutritional counselling using an MCT-containing formula and supplementations. Patients who showed an improvement in cholestasis had better responses. The initial assessment revealed low serum levels of 25-hydroxyvitamin D in 77.8 %, which increased significantly (p = 0.012). Conclusion Dietary intervention and supplementation with MCT and micronutrients can improve the nutritional status of children with BA following KPE.
