Optimal Fat-Modified Diet Duration for the Treatment of Postoperative Chylothorax in Children. Ann Thorac Surg 2024; 118:181-187. [PMID: 37308065 DOI: 10.1016/j.athoracsur.2023.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/12/2023] [Accepted: 05/16/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND Dietary modification is the mainstay of treatment for postoperative chylothorax in children. However, optimal fat-modified diet (FMD) duration to prevent recurrence is unknown. Our aim was to determine the association between FMD duration and chylothorax recurrence. METHODS Retrospective cohort study conducted across 6 pediatric cardiac intensive care units within the United States. Patients aged <18 years who developed chylothorax within 30 days after cardiac surgery between January 2020 and April 2022 were included. Patients with a Fontan palliation, who died, or were lost to follow-up or within 30 days of resuming a regular diet were excluded. FMD duration was defined as the first day of a FMD when chest tube output was <10 mL/kg/d without increasing until the resumption of a regular diet. Patients were classified into 3 groups (<3 weeks, 3-5 weeks, >5 weeks) based on FMD duration. RESULTS A total of 105 patients were included: <3 weeks (n = 61) 3-5 weeks (n = 18), and >5 weeks (n = 26). Demographic, surgical, and hospitalization characteristics were not different across groups. In the >5 weeks group, chest tube duration was longer compared with the <3 weeks and 3-5 weeks groups (median, 17.5 days [interquartile range, 9-31] vs 10 and 10.5 days; P = .04). There was no recurrence of chylothorax within 30 days once chylothorax was resolving regardless of FMD duration. CONCLUSIONS FMD duration was not associated with recurrence of chylothorax, suggesting that FMD duration can safely be shortened to at least <3 weeks from time of resolving chylothorax.

Abstract
Protein-losing enteropathy (PLE) describes a syndrome of excessive protein loss into the gastrointestinal tract, which may be due to a wide variety of etiologies. For children in whom the protein loss is associated with lymphangiectasia, medical nutrition therapy focused on restricting enteral long-chain triglycerides and thus intestinal chyle production is an integral component of treatment. This approach is based on the principle that reducing intestinal chyle production will concurrently decrease enteric protein losses of lymphatic origin. In patients with ongoing active PLE or those who are on a fat-restricted diet, particularly in infants and young children, supplemental calories may be provided with medium-chain triglycerides (MCT). MCT are absorbed directly into the bloodstream, bypassing intestinal lymphatics and not contributing to intestinal chyle production. Patients with active PLE or who are on dietary fat restriction should be monitored for associated micronutrient deficiencies. In this paper, we seek to formally present recommended nutrition interventions, principles of dietary education and patient counseling, and monitoring parameters in pediatric populations with PLE based on our experience in a busy clinical referral practice focused on this population.

Abstract
Children with congenital heart disease often require admission to the cardiac intensive care unit at some point in their lives, either after elective surgical or catheter-based procedures or during times of acute critical illness. Meeting both the macronutrient and micronutrient needs of children in the cardiac intensive care unit requires complex decision-making when considering gastrointestinal perfusion, vasoactive support, and fluid balance goals. Although nutrition guidelines exist for critically ill children, these cannot always be extrapolated to children with congenital heart disease. Children with congenital heart disease may also suffer unique circumstances, such as chylothoraces, heart failure, and the need for mechanical circulatory support, which greatly impact nutrition delivery. Guidelines for neonates and children with heart disease continue to be developed. We provide a synthesized narrative review of current literature and considerations for nutrition evaluation and management of critically ill children with congenital heart disease.

Development of consensus recommendations for the management of post-operative chylothorax in paediatric CHD. Cardiol Young 2022; 32:1202-1209. [PMID: 35792060 DOI: 10.1017/s1047951122001871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
OBJECTIVE A standardised multi-site approach to manage paediatric post-operative chylothorax does not exist and leads to unnecessary practice variation. The Chylothorax Work Group utilised the Pediatric Critical Care Consortium infrastructure to address this gap. METHODS Over 60 multi-disciplinary providers representing 22 centres convened virtually as a quality initiative to develop an algorithm to manage paediatric post-operative chylothorax. Agreement was objectively quantified for each recommendation in the algorithm by utilising an anonymous survey. "Consensus" was defined as ≥ 80% of responses as "agree" or "strongly agree" to a recommendation. In order to determine if the algorithm recommendations would be correctly interpreted in the clinical environment, we developed ex vivo simulations and surveyed patients who developed the algorithm and patients who did not. RESULTS The algorithm is intended for all children (<18 years of age) within 30 days of cardiac surgery. It contains rationale for 11 central chylothorax management recommendations; diagnostic criteria and evaluation, trial of fat-modified diet, stratification by volume of daily output, timing of first-line medical therapy for "low" and "high" volume patients, and timing and duration of fat-modified diet. All recommendations achieved "consensus" (agreement >80%) by the workgroup (range 81-100%). Ex vivo simulations demonstrated good understanding by developers (range 94-100%) and non-developers (73%-100%). CONCLUSIONS The quality improvement effort represents the first multi-site algorithm for the management of paediatric post-operative chylothorax. The algorithm includes transparent and objective measures of agreement and understanding. Agreement to the algorithm recommendations was >80%, and overall understanding was 94%.
