Aim of the study To assess the incidence and types of complications and patient-reported outcomes in pediatric patients with therapy-resistant constipation or fecal incontinence (FI) without constipation who underwent Chait TrapdoorTM cecostomy (CTC). The findings contribute to the discussion on selecting the optimal antegrade continence (ACE) procedure for this population. Materials and Methods A retrospective review was conducted on all pediatric patients with therapy-resistant constipation or FI without constipation who underwent a CTC procedure at our tertiary referral center between 2009 and 2023.

Objectives: To describe incidence, clinical course, diagnostic and therapeutic management and long-term follow-up of paediatric intestinal pseudo-obstruction (PIPO) in the Netherlands between 2000 and 2020.

Methods: Multicenter, national, retrospective, observational study including patients aged <18 years diagnosed with PIPO and treated between 2000 and 2020 in Dutch academic medical centres. Outcomes included demographics, incidence, symptoms, diagnostic- and treatment methods used during follow-up, number of hospital admissions and mortality.

Background: Despite optimal conservative and medical treatment, some children with functional constipation (FC) continue to experience symptoms. Antegrade continence enema (ACE) surgery has been suggested as the primary surgical option after less invasive pharmacological and non-pharmacological interventions have not been effective. The purpose of this systematic review was to assess the outcomes of ACE for children with FC.

Article Synopsis
  • Patients with pectus carinatum often experience lower quality of life and self-esteem, prompting a study on the effects of dynamic compression system bracing on these aspects.
  • In a study involving 225 patients aged 10-21, significant improvements were observed in quality of life scores within the first year of bracing treatment, specifically in physical and psychological health.
  • Most patients expressed high satisfaction with the treatment, with 87.2% indicating they would choose bracing again, despite no significant changes in anxiety levels.

Background: Long-term results and factors affecting outcomes of vacuum bell therapy for pectus excavatum are relatively unknown.

Methods: We conducted a retrospective study on patients (<18y) treated with vacuum bell therapy between May 2008 and October 2021. Primary outcome was treatment success; secondary outcomes were analysis of daily time spent on treatment, treatment duration, complications, long-term follow-up, treatment for patients awaiting a Nuss procedure, treatment for female patients, and factors affecting outcomes.

In patients born with anorectal malformations (ARM), additional congenital heart defects (CHD) can occur. We aimed to provide an overview on disease and treatment details of CHD identified in patients born with ARM, from a unique large cohort of a very rare disease. We performed a retrospective single-center cohort study between January 2000 and July 2023.

Functional constipation in the pediatric population is a prevalent issue that is usually well managed. However, in rare cases, conservative treatment fails, and surgical intervention is necessary. This retrospective cohort study aimed to describe and compare different perioperative analgesic techniques in children undergoing major abdominal surgery for intractable constipation.

Background: Congenital lung lesions in pediatric patients may be managed conservatively or by video assisted thoracoscopic surgery (VATS). This study aimed to determine the complications after VATS for congenital lung lesions in children.

Methods: All children undergoing a lung resection between January 2009 and June 2022 were retrospectively identified.

Purpose: First, to assess the number of patients with anorectal malformations (ARM) in whom additional urological and/or gynecological anomalies were identified through routine screening with cysto- or vaginoscopy prior to reconstructive surgery. Second, to assess potential procedure-related complications.

Methods: Retrospective mono-center cohort study, including all ARM patients born between January 2019 and December 2022.

Study Objective: In girls born with an anorectal malformation (ARM), anatomical gynecological anomalies (GA) may be present and might need treatment. Therefore, the aim of this study was to provide an overview of GA in girls born with ARM in our cohort. Additionally, diagnostic timing and methods for GA were assessed.

Background: Continence problems occur often in children with anorectal malformations (ARM). The aim of this study was to evaluate parental experiences with toilet facilities at Dutch primary schools and their experience with how schools deal with ARM children.

Methods: This survey was developed in collaboration with the national patient advocacy group (PAG).

Introduction:  A stoma will cause nutrients loss which could result in impaired growth. Impaired growth can negatively impact long-term development. This study aims to evaluate: (1) the effect of stomas on growth comparing small bowel stoma versus colostomy and (2) if early closure (within 6 weeks), proximal small bowel stoma (within 50 cm of Treitz), major small bowel resection (≥ 30 cm), or adequate sodium supplementation (urinary level ≤ 30 mmol/L) influences growth.

Article Synopsis
  • The study aimed to evaluate the occurrence of spinal cord anomalies, particularly tethered spinal cord, in patients with anorectal malformations using spinal cord imaging methods.
  • A total of 254 patients were analyzed, with 234 (92.1%) receiving spinal cord imaging, revealing that 22.2% had a spinal cord anomaly.
  • The findings suggest that screening for spinal cord anomalies is essential for all patients with anorectal malformations, regardless of their condition's complexity.

Objective: Discussion remains on how to advise women with a past medical history of surgically corrected anorectal malformations (ARMs) regarding vaginal delivery. The aim of this review is to evaluate and review the reported obstetrical complications and outcomes after vaginal delivery for these women.

Data Sources: A systematic search was performed from inception up to 25 July 2022 in PubMed, Embase.

Background: In children with anorectal malformations (ARM), additional anomalies can occur within the VACTERL-association. Routine screening is of great importance for early identification and potential treatment. However, uniformity in screening protocols is lacking and only small cohorts have been described in literature.

Background: Pectus carinatum is a pediatric condition that can be treated by dynamic compression system (DCS) bracing or surgery. Several publications on DCS bracing or surgery are available; however, they do not compare both treatments.

Methods: Over a 10-year period, 738 patients with pectus carinatum were treated at the Amsterdam Pectus Center (Amsterdam, The Netherlands).

Introduction: Contrast enemas are often made prior to stoma reversal in order to detect distal intestinal strictures distal of the stoma. If untreated these strictures can cause obstruction which might necessitate redo-surgery. However, the value of contrast enemas is unclear.

Background: Little is known about stoma related morbidity in young children. Therefore, the aim of this study is to assess major morbidity after stoma formation and stoma closure and its associated risk factors.

Methods: All consecutive young children (age ≤ three years) who received a stoma between 1998 and 2018 at our tertiary referral center were retrospectively included.

Unlabelled: Fifth-generation, round, form-stable implants have a higher cohesive gel, a higher fill volume, and distinct anterior and posterior profiles. Due to these implant features, anterior-posterior (AP) flipping of round, form-stable implants is discernible, but little is known of this complication of implant reconstruction.

Methods: Patients who underwent skin- or nipple-sparing mastectomy followed by direct-to-implant reconstruction with round, cohesive, smooth implants were included in this retrospective study.
