Choledochal Malformation in Children: Lessons Learned from a Dutch National Study

Introduction: A choledochal malformation (CM) is a rare entity, especially in the Western world. We aimed to determine the incidence of CM in the Netherlands and the outcome of surgery for CM in childhood. Methods: All pediatric patients who underwent a surgical procedure for type I–IV CM between 1989 and 2014 were entered into the Netherlands Study group on choledochal cyst/malformation. Patients with type V CM were excluded from the present analysis. Symptoms, surgical details, short-term (30 days) complications were studied retrospectively. Results: Between January 1989 and December 2014, 91 pediatric patients underwent surgery for CM at a median age of 2.1 years (0.0–17.7 years). All patients underwent resection of the extrahepatic biliary tree with restoration of the continuity via Roux-en-Y hepaticojejunostomy. Twelve patients (12%) were operated laparoscopically. Short-term complications, mainly biliary leakage and cholangitis, occurred in 20 patients (22%), without significant correlations with weight or age at surgery or surgical approach. Long-term postoperative complications were mainly cholangitis (13%) and anastomotic stricture (4%). Eight patients (9%) required radiological intervention or additional surgery. Surgery before 1 year of age (OR 9.3) and laparoscopic surgery (OR 4.4) were associated with more postoperative long-term complications. We did not observe biliary malignancies during treatment or follow-up. Conclusion: Surgery for CM carries a significant short- and long-term morbidity. Given the low incidence, we would suggest that (laparoscopic) hepatobiliary surgery for CM should be performed in specialized pediatric surgical centers with a wide experience in laparoscopy and hepatobiliary surgery

High prevalence of non-accidental trauma among deceased children presenting at Level I trauma centers in the Netherlands

PURPOSE: Between 0.1—3% of injured children who present at a hospital emergency department ultimately die as a result of their injuries. These events are typically reported as unnatural causes of death and may result from either accidental or non-accidental trauma (NAT). Examples of the latter include trauma that is inflicted directly or resulting from neglect. Although consultation with a forensic physician is mandatory for all deceased children, the prevalence of fatal inflicted trauma or neglect among children is currently unclear. METHODS: This is a retrospective study that included children (0–18 years) who presented and died at one of the 11 Level I trauma centers in the Netherlands between January 1, 2014, and January 1, 2019. Outcomes were classified based on the conclusions of the Child Abuse and Neglect team or those of forensic pathologists and/or the court in cases referred for legally mandated autopsies. Cases in which conclusions were unavailable and there was no clear accidental cause of death were reviewed by an expert panel. RESULTS: The study included 175 cases of childhood death. Seventeen (9.7%) of these children died due to inflicted trauma (9.7%), 18 (10.3%) due to neglect, and 140 (80%) due to accidents. Preschool children (< 5 years old) were significantly more likely to present with injuries due to inflicted trauma and neglect compared to older children (44% versus 6%, p < 0.001, odds ratio [OR] 5.80, 95% confidence interval [CI] 2.66–12.65). Drowning accounted for 14 of the 18 (78%) pediatric deaths due to neglect, representing 8% of the total cases. Postmortem radiological studies and autopsies were performed on 37 (21%) of all cases of childhood death. CONCLUSION: One of every five pediatric deaths in our nationwide Level I trauma center study was attributed to NAT; 44% of these deaths were the result of trauma experienced by preschool-aged children. A remarkable number of fatal drownings were due to neglect. Postmortem radiological studies and autopsies were performed in only one-fifth of all deceased children. The limited use of postmortem investigations may have resulted in missed cases of NAT, which will result in an overall underestimation of fatal NAT experienced by children.

Emergency treatment of allergic reactions to Hymenoptera stings

Allergic reactions to Hymenoptera stings are frequently observed all over Europe. Rarely they may induce long-standing morbidity or even be fatal. Several investigations have shown that the emergency treatment given to these patients is often inadequate. Cutaneous symptoms respond well to antihistamines and also to adrenaline. Adrenaline is the mainstay for outside hospital treatment of more severe reactions involving the respiratory tract (bronchial asthma, laryngeal oedema) and the cardiovascular system (anaphylactic shock). Inhaled adrenaline is especially useful in respiratory symptoms, while parenteral application of adrenaline is preferred for shock treatment. All patients with severe respiratory or cardiovascular reactions must be hospitalized, treated under intensive care conditions and observed for at least 24 hr. Emergency medications including adrenaline for inhalation or for self-injection must be given to all patients with a history of systemic allergic reactions to hymenoptera stings. These patients must also get instructions for safety measures to avoid further stings. They should be referred to an allergist in order to evaluate the indication for venom immunotherapy

The timing of surgery of antenatally diagnosed choledochal malformations: A descriptive analysis of a 26-year nationwide cohort

INTRODUCTION: Choledochal malformations (CMs) are increasingly diagnosed antenatally. There is a dilemma between early surgery to prevent CM-related symptoms and postponing surgery to reduce complications. We aimed to identify the optimal timing of surgery in asymptomatic neonates with antenatally diagnosed CM and to identify predictors for development of symptoms. METHODS: Using the Netherlands Study group on CHoledochal Cyst/malformation (NeSCHoc) we retrospectively collected demographic, biochemical and surgical data from all Dutch patients with an antenatally detected CM. RESULTS: Between 1989 and 2014, antenatally suspected CM was confirmed in 17 patients at a median age of 10days (1day-2months). Four patients developed symptoms directly after birth (24%). Thirteen patients (76%) remained asymptomatic. Two of these progressed to symptoms before surgical intervention at 0.7 and 2.1months resp. Postoperatively, four patients developed short-term complications and three developed long-term complications. Patients 5.6kg (0%, p=0.02). CONCLUSION: When not symptomatic within the first days of life, the majority of children with antenatally detected CM remains asymptomatic. Surgery might safely be delayed to the age of 6months or a weight of 6kg. Postponing surgery in the clinically and biochemical asymptomatic patient might decrease the complication rate. LEVELS OF EVIDENCE: Level III

Preterm Infants with Biliary Atresia : A Nationwide Cohort Analysis from the Netherlands

Objectives: Biliary atresia (BA) occurs in 0.54 of 10.000 of overall live births in the Netherlands. BA has an unfavorable prognosis: <40% of patients are cleared of jaundice after Kasai portoenterostomy (KPE), 4-year transplant-free survival rate is 46% and the 4-year survival rate is ∼75%. Little is known on difficulties in diagnosis and the outcome of BA in preterm infants. We aimed to analyze the incidence and outcome of BA in preterm infants in the Netherlands. Methods: Retrospective study including Dutch preterm infants treated for BA. Parameters included gestational age, congenital anomalies, age at KPE, days between first symptoms, and KPE and referral interval (first hospital to KPE). Outcome parameters were clearance of jaundice (COJ) and (transplant-free) survival. Data are presented as medians (ranges). Results: Included 28 preterm infants (13 boys/15 girls) between March 1988 and December 2015. The incidence of BA was 1.06 of 10.000 preterm live births. Gestational age was 34.8 (27.3-36.9) weeks. Congenital anomalies were present in 11 of 28 (39%) infants. Time between first symptoms and KPE was 57 (9-138) days. Referral interval was 28 (8-86) days. Age at KPE was 70 (35-145) days. COJ was achieved in 23% of cases. Four-year transplant-free survival rate was 21%. Four-year overall survival was 61%. Conclusions: BA has a higher incidence in the preterm population compared to the overall BA population. The outcome of BA in preterm infants is poor, regarding COJ and (transplant-free) survival. We speculate that timely recognition of BA-related signs and symptoms in preterm infants will improve prognosis
