Essential fatty acid deficiency in congenital biliary atresia: successful treatment to reverse deficiency
Insights
Essential fatty acid (EFA) deficiency in children with congenital biliary atresia (CBA) can be treated by infusing EFA-rich powder. Dissolving the powder in bile, with added taurocholate if needed, aids lipid absorption and corrects deficiency.
Area of Science:
- Pediatric Gastroenterology
- Nutritional Science
- Surgical Outcomes
Background:
- Congenital biliary atresia (CBA) often leads to essential fatty acid (EFA) deficiency post-surgery.
- Impaired bile acid synthesis or flow can hinder lipid absorption in these patients.
Purpose of the Study:
- To evaluate the efficacy of essential fatty acid (EFA)-rich lipid supplementation via enterostomy in children with postoperative CBA.
- To determine the role of bile acid concentration and taurocholate (TC) in facilitating lipid absorption.
Main Methods:
- Infusion of EFA-rich powder dissolved in excreted bile through Suruga II enterostomy in nine children with postoperative CBA.
- Analysis of bile acid concentration and intervention with taurocholate (TC) solution for patients with low bile acid levels.
Main Results:
- EFA supplementation was effective in six out of nine patients.
- One patient with critically low bile acid levels did not respond initially.
- Supplementation using EFA-rich powder dissolved in bile with 1-2 mmol/L taurocholate (TC) successfully corrected EFA deficiency in three children with low bile acid concentrations.
Conclusions:
- Infusion of EFA-rich lipid via enterostomy is an effective treatment for EFA deficiency in postoperative CBA patients.
- The addition of 1-2 mmol/L taurocholate (TC) solution as artificial bile enhances lipid absorption in patients with insufficient endogenous bile acids.
Abstract:
Supplementation of lipid intake by infusion of solutions of essential fatty acid (EFA)-rich powder through Suruga II enterostomy was carried out for the treatment of EFA deficiency in nine children with postoperative congenital biliary atresia (CBA). Infusion of EFA-rich powder dissolved in excreted bile was effective in six patients except for a case who had a total bile acid concentration in the excreted bile that was less than critical micellar level. Administration of EFA-rich powder dissolved in a mixture of the patient's own bile and 1 to 2 mmol/L taurocholate (TC) solution corrected EFA deficiency in three children with total bile acid concentration lower than the critical level. Our results therefore show that infusion of EEA-rich lipid through Suruga II enterostomy after dissolving in the excreted bile is an effective treatment for EFA deficiency in postoperative patients with CBA, and that 1 to 2 mmol/L TC solution used as artificial bile facilitates lipid absorption in cases with total bile acid in the bile less than the critical micellar level.
