Paediatric Adhesive Small Bowel Obstruction is Associated with a Substantial Economic Burden and High Frequency of Postoperative Complications

BACKGROUND

Intra-abdominal adhesions can lead to adhesive small bowel obstruction (ASBO). The incidence of ASBO is higher in paediatric surgery than in adult surgery. However, ASBO related complications, economic burden and clear management guidelines in the treatment of ASBO are lacking. The aims of this study were to investigate underlying diagnoses, treatments, complications and costs in paediatric ASBO.

METHOD

An observational retrospective study in children 0-15 years, hospitalised for ASBO during 2000-2020. Data were extracted from the medical records. Complications were classified based on Clavien Dindo Classification of Surgical Complications. Descriptive statistics were presented as median, continuous variables and categorical variables summarised with frequencies. Time to ASBO was presented as a Kaplan-Meier estimate.

RESULTS

In total, 101 patients with 137 episodes of ASBO were included whereof 58.4% underwent first (index) surgery during the neonatal period. Median follow-up was 11.3 (0.6-19) years and median time to the first ASBO was 3.76 months (95%CI 2.23-12.02). The most common diagnoses at index surgery were necrotising enterocolitis, duodenal obstruction and primary ASBO. In 86.6% of the patients, first ASBO did not resolve with conservative treatment and a laparotomy was needed. Postoperative complications were found in 52%. Median cost for one episode of acute ASBO was 36 236 USD (1629-236 159).

CONCLUSION

Neonatal surgery was the dominating cause of ASBO and surgical intervention the most common treatment with a high frequency of postoperative complications and significant healthcare costs. Future studies are needed to develop safe management guidelines for the treatment of paediatric ASBO.

The risk of autism spectrum disorder and intellectual disability but not attention deficit/hyperactivity disorder is increased in individuals with esophageal atresia

Knowledge of neurodevelopmental disorders such as attention deficit/hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and intellectual disability (ID) in patients with esophageal atresia (EA) is scarce. The aims of this study were to investigate the prevalence and risk of ADHD, ASD and ID in individuals with EA. Data were obtained from four longitudinal population-based registries in Sweden and analyzed using Cox proportional hazards regression. Patients with EA born in Sweden in 1973-2018 were included together with five controls for each individual with the exposure matched on sex, gestational age at birth, birth year and birth county. Individuals with chromosomal aberrations and syndromes were excluded. In total, 735 individuals with EA and 3675 controls were included. Median age at time of the study was 20 years (3-48). ASD was found in 24 (3.9%), ADHD in 34 (5.5%) and ID in 28 (4.6%) individuals with EA. Patients with EA had a 1.66 times higher risk of ASD (95% confidence interval [CI], 1.05-2.64) and a 3.62 times higher risk of ID (95% CI, 2.23-5.89) compared with controls. The risk of ADHD was not significantly increased. ADHD medication had been prescribed to 88.2% of patients with EA and ADHD and to 84.5% of controls with ADHD. Individuals with EA have a higher risk of ASD and ID than individuals without the exposure. These results are important when establishing follow-up programs for children with EA to allow timely detection and consequentially an earlier treatment and support especially before school start.

Attention deficit hyperactivity disorder and educational level in adolescent and adult individuals after anesthesia and abdominal surgery during infancy

AIM

Several studies in animal models have found that exposure to anesthetics in early life can cause cognitive dysfunction. Human studies show conflicting results and studies of cognitive function after anesthesia and neonatal surgery are scarce. The aim of this study was to investigate whether exposure to anesthesia and abdominal surgery during infancy was associated with cognitive dysfunction from the perspective of educational level, disposable income and attention deficit hyperactivity disorders (ADHD) in adolescent and adult individuals.

METHODS

A cohort study with patients born 1976 to 2002 that underwent abdominal surgery during infancy at a pediatric surgical center were matched by age, sex, and gestational age to ten randomly selected individuals from the Swedish Medical Birth Register. Individuals with chromosomal aberrations were excluded. Data on highest level of education and annual disposable income were attained from Statistics Sweden and the diagnosis of ADHD were retrieved from the Swedish National Patient Register.

RESULTS

485 individuals and 4835 controls were included. Median gestational age was 38 weeks (24-44) and median age at surgery was seven days (0-365). Three hundred sixty-six individuals (70.0%) underwent surgery during the neonatal period (< 44 gestational weeks). Median operating time was 80 minutes (10-430). The mean age at follow-up was 28 years. Fisher's exact test for highest level of education for the exposed and unexposed groups were respectively: university 35% and 33%, upper secondary 44% and 47%, compulsory 21% and 20% (p = 0.6718). The median disposable income was 177.7 versus 180.9 TSEK respectively (p = 0.7532). Exposed individuals had a prevalence of ADHD of 5.2% and unexposed 4.4% (p = 0.4191).

CONCLUSIONS

This study shows that exposure to anesthesia and abdominal surgery during infancy is not associated with cognitive dysfunction from the perspective of educational level, disposable income and ADHD in adolescent and adult individuals. Further studies in larger cohorts at earlier gestational ages are needed to verify these findings.
