Effects of postoperative adjuvant steroid therapy on the outcomes of biliary atresia: A systematic review and updated meta-analysis

Major surgical conditions of childhood and their lifelong implications: comprehensive review

BACKGROUND

In recent decades, the survival of children with congenital anomalies and paediatric cancer has improved dramatically such that there has been a steady shift towards understanding their lifelong health outcomes. Paediatric surgeons will actively manage such conditions in childhood and adolescence, however, adult surgeons must later care for these 'grown-ups' in adulthood. This article aims to highlight some of those rare disorders encountered by paediatric surgeons requiring long-term follow-up, their management in childhood and their survivorship impact, in order that the adult specialist may be better equipped with skills and knowledge to manage these patients into adulthood.

METHODS

A comprehensive literature review was performed to identify relevant publications. Research studies, review articles and guidelines were sought, focusing on the paediatric management and long-term outcomes of surgical conditions of childhood. The article has been written for adult surgeon readership.

RESULTS

This article describes the aforementioned conditions, their management in childhood and their lifelong implications, including: oesophageal atresia, tracheo-oesophageal fistula, malrotation, short bowel syndrome, duodenal atresia, gastroschisis, exomphalos, choledochal malformations, biliary atresia, Hirschsprung disease, anorectal malformations, congenital diaphragmatic hernia, congenital lung lesions and paediatric cancer.

CONCLUSION

The increasing survivorship of children affected by surgical conditions will translate into a growing population of adults with lifelong conditions and specialist healthcare needs. The importance of transition from childhood to adulthood is becoming realized. It is hoped that this timely review will enthuse the readership to offer care for such vulnerable patients, and to collaborate with paediatric surgeons in providing successful and seamless transitional care.

A convenient nomogram for predicting early death or liver transplantation after the Kasai procedure in patients with biliary atresia

PURPOSE

Many patients with biliary atresia (BA) after the Kasai procedure (KP) progress to death or require liver transplantation to achieve long-term survival; however, most cases of death/liver transplantation (D/LT) occur in the early period after KP (usually within 1 year). This study was designed to construct a convenient nomogram for predicting early D/LT in patients with BA after KP.

METHODS

A BA cohort was established in May 2017, and up to May 2023, 112 patients with 1-5 years of follow-up were enrolled in the study and randomly (ratio, 3:1) divided into a training cohort for constructing a nomogram (n = 84) and a validation cohort (n = 28) for externally validating the discrimination and calibration. The training cohort was divided into two groups: the early D/LT group (patients who died or had undergone LT within 1 year after KP [n = 35]) and the control group (patients who survived through the native liver more than 1 year after KP [n = 49]). Multivariate logistic regression and stepwise regression were applied to detect variables with the best predictive ability for the construction of the nomogram. The discrimination and calibration of the nomogram were internally and externally validated.

RESULTS

The Kaplan-Meier (K-M) curve showed an actual 1-year native liver transplantation (NLS) rate of 57.1% and an estimated 2-year NLS rate of 55.2%. By multivariate regression and stepwise regression, age at KP, jaundice clearance (JC) speed 1 month after KP, early-onset PC (initial time < 36.5 days) after KP, sex, aspartate aminotransferase-to-platelet ratio index (APRI), and weight at KP were identified as the independent variables with the best ability to predict early D/LT and were used to construct a nomogram. The developed nomogram based on these independent variables showed relatively good discrimination and calibration according to internal and external validation.

CONCLUSION

Most D/LTs were early D/LTs that occurred within 1 year after KP. The established nomogram based on predictors, including sex, weight at the KP, the APRI, age at the KP, JC speed 1 month after the KP, and early PC, may be useful for predicting early D/LT and may be helpful for counseling BA patients about patient prognosis after KP. This study was retrospectively registered at ClinicalTrials.gov (NCT05909033) in June 2023.

Biliary atresia in children (analytical literature review and review of own observation)

OBJECTIVE

Aim: to review information resources and analysis of the own experience on this problem for the provision of modern knowledge in the pathogenesis of the pathology, the latest diagnostic and treatment technologies, with consideration of the need to adhere to a single strategy in the management of patients with BA.

PATIENTS AND METHODS

Materials and Methods: The analysis of the data regarding the results of existing studies evaluating the clinical benefit and safety of diagnostic and treatment methods in Biliary atresia.

CONCLUSION

Conclusions: BA is the leading cause of neonatal cholestasis development. Early diagnostics of BA, based on the complex evaluation of clinical-laboratory, instrumental and morphological signs of the pathology, has a significant meaning. Surgical correction during the first 2 months of life - the Kasai procedure, as well as dynamic post-surgery follow-up significantly prolong the life of children and allow postponing liver transplantation. The highest patient survival both at the first stage of treatment - conduction of the Kasai procedure and the stage of liver transplantation may be achieved by joined work of surgeons and pediatricians, which allows considering the whole row of possible problems.

Prognostic factors and outcomes of Kasai portoenterostomy (KPE): nine-year experience from a lower-middle income country

PURPOSE

Outcome data after Kasai portoenterostomy (KPE) reported worldwide show considerable regional and institutional variation. It is not known whether the same standards of outcomes reported in western world can be replicated in resource-poor countries.

METHODS

We reviewed 79 patients of which 43 had completed a 2-year minimum follow-up. Two cohorts were based on age at KPE. The median age at surgery was 60 days.

RESULTS

Clearance of jaundice (COJ) at 3 months was 20.93% and was not affected by age at surgery (p = 0.295). Four patients (9.3%) received liver transplant and 16 patients (37.21%) were recorded dead at a median age of 7 months. Native liver survival (NLS) was 53.49% and overall survival (OS) was 62.79%. Kaplan-Meier estimated 4- and 6-year NLS were 55.8% and 49.6%, respectively. There was a significant difference in the NLS between early and late surgery groups.

CONCLUSION

While causes for low COJ need to be explored, these data reaffirm that early surgery has a significant favorable effect on survival. NLS was comparable with data from the developed world, whereas low OS is explained by limited access to transplant. Thus, where the survival depends on native liver longevity, emphasis should be on as early KPE as possible.

Dexamethasone may affect the occurrence of parenteral nutrition-associated cholestasis in preterm neonates

INTRODUCTION

Glucocorticoids are currently used for the co-therapeutic management of autoimmune hepatitis and some cholestatic diseases. Thus far, we do not know the efficacy of glucocorticoids in the treatment of parenteral nutrition-associated cholestasis. We aimed to analyze whether the administration of late postnatal dexamethasone for treating bronchopulmonary dysplasia influence the occurrence of parenteral nutrition-associated cholestasis in preterm neonates.

METHODS

A retrospective study was conducted for 78 preterm neonates without major anomalies (gestational age was <30 weeks, and birthweight was ≤1000 g) hospitalized in a neonatal unit. Total and direct serum bilirubin levels were measured about every two weeks for all neonates. Data including the administration of dexamethasone, intravenous nutrition, and enteral feeding were collected by at least three audits.

RESULTS

A total of 15 preterm neonates were diagnosed with parenteral nutrition-associated cholestasis, and after stopping parenteral nutrition, the direct bilirubin value decreased to the normal level for no longer than 150 days. The prolonged duration of parenteral nutrition was a risk factor, and late postnatal dexamethasone treatment was a protective factor in reducing the incidence of parenteral nutrition-associated cholestasis.

CONCLUSION

Dexamethasone treatment may reduce the occurrence of parenteral nutrition-associated cholestasis in preterm neonates.
