Background: Over half of preterm neonates with necrotizing enterocolitis (NEC) require surgery, making it essential to understand short-term postoperative outcomes and complication rates. Therefore, this study aimed to provide an overview of 30-day postoperative complications for NEC. Secondary, risk factors for minor and major short-term postoperative complications were identified.

Study Objective: Necrotizing enterocolitis (NEC) is a life-threatening intestinal illness mostly affecting preterm infants, which commonly requires surgery. Anesthetic care for these patients is challenging, due to their prematurity and critical illness with hemodynamic instability. Currently, there are no guidelines for anesthetic care for these vulnerable patients.

The growing population of survivors following pediatric surgery emphasizes the importance of long-term follow-up. The impact of surgical scars on daily life can be evaluated through patient-reported outcome measurements. The Stony Brook Scar Evaluation Scale (SBSES) and SCAR-Q questionnaire are two interesting instruments for this purpose.

Introduction:  To improve counseling of parents and to guide care strategies, we studied the disease course and outcomes of necrotizing enterocolitis (NEC) up to 2 years of corrected age (CA) from a multidisciplinary perspective.

Materials And Methods:  This was a retrospective cohort study in preterm infants (birth weight < 1,500 g, gestational age < 32 weeks), diagnosed with NEC (Bell's stage ≥ II) from 2008 through 2020. Data on prevalence, mortality, surgery, intestinal failure (IF), growth, and neurodevelopment at 2-year follow-up were separately analyzed for medically and surgically treated children.

Objectives: To longitudinally evaluate self-reported and proxy-reported health status (HS) and quality of life (QoL) of school-aged children born with esophageal atresia (EA).

Methods: We obtained Pediatric Quality of Life Inventory (HS) and DUX-25 (QoL) questionnaires from children born with EA between 1999 and 2011 at 8 and/or 12 years old. Children completed self-reports during neuropsychological assessments in a prospective longitudinal follow-up program.

Introduction:  Studies report contradicting results on the incidence of infantile hypertrophic pyloric stenosis (IHPS) and its association with seasons. We aim to assess the IHPS incidence in the Netherlands and to determine whether seasonal variation is present in a nationwide cohort.

Materials And Methods:  All infants with IHPS hospitalized in the Netherlands between 2007 and 2017 were included in this retrospective cohort study.

Objective: To assess the role of sex in the presentation and management of children attending the emergency department (ED).

Design: The TrIAGE project (TRiage Improvements Across General Emergency departments), a prospective observational study based on curated electronic health record data.

Setting: Five diverse European hospitals in four countries (Austria, The Netherlands, Portugal, UK).

Objective: The aim of this study was to determine whether written and video instructions improved the recall of how to use analgesics correctly in parents of children discharged following assessment in the emergency department (ED).

Methods: This was a prospective pre- and post-implementation study set in the EDs of a tertiary teaching hospital and an urban general hospital in the Netherlands. The participants were parents/carers of children under 12-years-old who had been assessed in and subsequently discharged from the ED.

Introduction:  Infants with hypertrophic pyloric stenosis have gastric outlet obstruction, indicating a pyloromyotomy. To prevent aspiration, a rapid sequence induction (RSI) of anesthesia used to be preferred. However, due to concerns about the side-effects of this technique in infants, a modified RSI with gentle mask ventilation is nowadays mostly used.

Background: Perioperative music interventions have been shown to reduce anxiety and pain in adults. This inexpensive, easily applicable intervention could be of benefit to children as well. Our objective was to determine the effects of music interventions on distress, anxiety, and postoperative pain in infants undergoing surgery.

Background:  In 2011, we implemented a new video-based system for quality control of laparoscopic pyloromyotomy. More than 3 years later, we evaluated how the implementation had gone and assessed its usability in predicting postoperative outcomes.

Materials And Methods:  Four key point images or short video-segments were to be recorded perioperatively: prepyloromyotomy, parallel-mobility testing, perforation testing, and postpyloromyotomy.

Background: Postoperatively, young infants are admitted overnight in view of the risk for respiratory complications such as desaturation and apnea. This risk seems much lower than previously reported. Until what age this risk persists, and which infants might actually qualify for day-care treatment, is unknown.

Background:  Epidural analgesia (EDA) is used as postoperative pain treatment in children, but little is known about its efficacy after laparotomy in children. This retrospective study investigated the efficacy of postoperative EDA after laparotomy in children and the frequencies of adverse effects and complications.

Materials And Methods:  Data of all children aged 0 to 18 years undergoing laparotomy and treated with EDA in our hospital from January 2014 to December 2015 were collected.

Background: Necrotizing enterocolitis (NEC) is known as an extremely painful childhood condition.

Objectives: The objective of this study was to explore pain management around NEC-related surgery in our neonatal intensive care unit (NICU) from a chart review of prospectively collected data on 60 operated NEC patients admitted between 2008 and 2013 with a median (IQR) gestational age of 28.3 (25.

Introduction: Rectal suction biopsy (RSB) is performed on clinical and radiological suspicion of Hirschsprung disease (HD). Positive histochemical staining for acetylcholinesterase in the lamina propria mucosa and muscularis mucosa together with the absence of ganglion cells in the submucosa confirms HD. A second RSB or a full-thickness biopsy is done in case of doubt.

Objectives: High trait anxiety (HTA) determines depressive symptoms and state anxiety in women with breast cancer (BC) or benign breast disease (BBD). Before implementing screening for psychological counselling in these women, it is important to evaluate whether high state anxiety and depressive symptoms are determined by (the threat of) having BC or solely by HTA. Therefore, we compared women with a lump in the breast with women with gallstone disease (GD).

Introduction: Gaining an insight into the quality of life (QOL) in long-term biliary atresia (BA) survivors is becoming more important. Identifying patients with limitations might make tailor made interventions possible. This is the first study investigating the health status (HS) and QOL in adults surviving BA with their native livers, and comparing them with healthy peers.

Background: High trait anxiety (HTA) causes an impaired quality of life (QOL) and fatigue in women with breast cancer (BC) and benign breast disease (BBD). We examined whether the lowered QOL was determined solely by the personality characteristic HTA or by the combination of personality and diagnosis.

Methods: In a prospective longitudinal study, women with BC (n = 152), BBD (n = 205), or gallstone disease (GD) before laparoscopic cholecystectomy (n = 128) were included.
