Background/purpose:  Gastroesophageal reflux disease (GERD) after lung transplantation (LuTx) can lead to chronic lung allograft dysfunction. Our aim was to assess the prevalence of GERD in pediatric LuTx recipients and to investigate the impact of medical and surgical GERD treatment on lung function.

Methods:  Ethical approval was obtained. Data of all consecutive patients who underwent LuTx from 2013 to 2023 and aged < 18 years at the time of the study were prospectively collected. A GERD diagnostic algorithm was established, including assessment of symptoms (vomiting, heartburn, regurgitation, cough, recurrent airway infections), bronchoscopy, forced expiratory volume in 1 second, and pH impedance. Further investigations included upper gastrointestinal series and esophagogastroduodenoscopy. Patients with GERD underwent medical treatment or fundoplication. Lung function was monitored.

Results:  Thirty-six patients (2 months-18 years, 50% male) were included. Twenty-nine (80%) underwent spirometry, 16 (45%) pH impedance study, and 14 (39%) esophagogastroduodenoscopy. Twenty-two (61%) had no GERD symptoms and 12 (33%) showed normal pH impedance study or esophagogastroduodenoscopy. Fourteen (39%) patients had GERD symptoms, all 9 tested symptomatic patients (25%) had pathological GERD-specific diagnostics. Three (8%) patients underwent fundoplication after a median of 1.6 years (range 1.1-5.7 years) post-LuTx without surgical complications. After a median follow-up of 2.3 years (range 1.3-2.8 years) post-fundoplication, all (n = 3) had complete remission of GERD symptoms and lung function improvement. Lung function decline was observed in 6 (67%) of the tested symptomatic patients on proton-pump inhibitors (PPIs) treatment.

Conclusion:  Over one-third of our patients presented with GERD symptoms after LuTx. Symptoms and lung function may be reliable GERD indicators. Given the high prevalence of GERD, we suggest a routine posttransplant diagnostic algorithm including pH impedance study. Eighty percent of all symptomatic patients had a lung function decline despite PPI. Fundoplication is safe and may improve long-term outcome in pediatric LuTx recipients.

Aim:  This survey analyzed techniques in laparoscopic inguinal hernia repair (LIHR) across pediatric age groups.

Materials and methods:  Data were collected through an online survey for pediatric surgeons, comprising of 38 questions, conducted by the European Pediatric Surgeons' Association (EUPSA) Trainees of European Pediatric Surgery (TEPS) LIHR Working Group.

Results:  The survey was completed by 183 surgeons from 22 countries. Seventy-seven percent of respondents had performed LIHR at least once. Regarding preferences about the patient's gender, 7% respondents perform LIHR only in selected females, 9% routinely in females, 15% in both genders with age/weight restrictions, 24% routinely in both genders, 31% in selected cases, and 14% never perform LIHR. Percutaneous internal ring suturing (PIRS) was the preferred technique in all age groups, with totally extraperitoneal and transabdominal preperitoneal repairs preferred by 9% in adolescents. The majority (59%) repaired a contralateral patent processus vaginalis if present. Hydro-dissection (21%) and additional intra-abdominal instruments (42%) were preferred more often for male patients. The distal hernia sac was left intact by most respondents (92%). Responses regarding recurrence rates varied: 40% responded that LIHR had recurrence rates comparable to open surgery, whereas 10% reported increased recurrences and hence limited its use, and 10% consider that slightly increased recurrences are outweighed by lower complication rates associated with laparoscopic methods and thus continue LIHR.

Conclusions:  PIRS is the preferred choice for pediatric LIHR. Surgical techniques vary and are influenced by patient gender and age. The survey gives insights into demographics, case selection, and approaches among pediatric surgeons with regard to LIHR.

Introduction:  The objective of this study is to analyze the conversion rate of abstracts presented at the European Paediatric Surgeons' Association (EUPSA) congress into full-text publications and to conduct a thorough analysis of the attributes and quality of the papers published.

Materials and methods:  Abstract books including the years 2017 to 2022 were reviewed. Searches on PubMed and Google Scholar, utilizing keywords from the titles and the author names, were conducted to trace subsequent full-text publications. A categorical analysis detected variations and trends, with a significance threshold of p < 0.05. Quantitative data were presented as means ± standard deviations, whereas categorical data were represented as counts (n) and percentages (%).

Results:  A total of 2,139 abstracts were presented at the EUPSA annual meetings during five consecutive congresses. The average number of presented abstracts was 427.6 ± 20.4 per year from across 63 different countries. European countries contributed the majority (71%). The presentations included both oral (n = 817, 38.2%) and poster presentations (n = 1,322, 61.8%). They predominantly focused on clinical topics (90.6%). Single-center retrospective studies were the most common study design (43.7%). Out of all abstracts presented, 1,033 (48.3%) were published within an average time interval of 1.39 ± 1.19 years after presentation. Most journals had an impact factor (IF) between 1 and 5 (74.5%). There was no significant year-to-year variation in publication rates (p = 1). Basic science studies were published in journals with significantly higher IF compared with clinical studies (p < 0.001).

Conclusions:  The publication rate of abstracts presented at the EUPSA annual congress stands at 48.3%, aligning with the rates observed in other similar studies. This suggests that abstracts submitted to the EUPSA congresses were evaluated and scored rigorously, adhering to international selection criteria. Furthermore, the majority of these abstracts were published in journals with moderate to high IFs, providing quantitative evidence of the scientific quality of research within the field of pediatric surgery.

Background:  Esophageal atresia (EA) is a rare disease requiring surgical repair, usually within the first days of life. Patients with EA require intensive postoperative care and often have comorbidities. There is a lack of data on the costs incurred by patients with EA during the first year of life.

Methods:  Anonymized claims data were provided by the Techniker Krankenkasse (∼10.8 million clients). Data were extracted for patients who had an inpatient diagnosis of EA (International Classification of Diseases [ICD]: Q39.0 or Q39.1) and a reconstruction of the esophageal passage in case of atresia (Operationen-und Prozedurenschlüssel [German version of ICPM, International Classification of Procedures in Medicine; OPS] 5-428.0 to 5-428.7, 5-316.1 or 5-431.0) during their first hospital stay. All patients were in their first year of life at initial hospitalization (2016-2020) and were followed up for 1 year. Costs, length of hospital stay, and duration of mechanical ventilation and differentiated OPS services were analyzed using descriptive statistics. Multiple linear regression was used to analyze the determinants of hospital costs.

Results:  A total of 119 patients with EA were included (55.5% male). The mean cost of the 1-year observation period was €89,736 ± 97,419 (range €12,755-640,154). The increasing costs of the initial hospitalization led to a disproportionate increase in the costs of the 1-year observation period. The presence of an associated malformation combined with surgical complications was associated with almost five-fold higher costs than in patients without an associated malformation and an uncomplicated course (€193,103 ± 157,507 vs. €39,846 ± 33,473). The mean duration of mechanical ventilation was 23.2 ± 43.1 days and the mean length of hospital stay was 80.3 ± 77.2 days.

Conclusion:  To our knowledge, this is the first study to investigate the costs of EA patients in the first year of life. The presence of an associated malformation combined with surgical complications was associated with almost five-fold higher costs than in patients without an associated malformation and an uncomplicated course.

Introduction:  Intra-abdominal testis (IAT) remains a challenging and controversial subset within the management of cryptorchidism. While Fowler-Stephens orchidopexy (FSO) is still being advocated as the gold standard for the treatment of this entity, there is new and conflicting evidence on the comparative outcomes between single- or two-stage laparoscopic FSO (LFSO). The aim of the study is to investigate whether staging has benefits in children receiving LFSO.

Methods:  We searched the PubMed, Medline, Embase, and Cochrane Trials databases for studies comparing single- with two-stage LFSO in children from January 1, 1995 to December 31, 2023. We assessed the identified studies for quality and performed a systematic review and meta-analysis in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analyses. The main outcome measures examined were success rate (in terms of the scrotal position of the testis) and testicular atrophy, which were analyzed using fixed effect models.

Results:  We included 17 eligible studies that involved a total of 499 operated testes. The overall success rates of single- and two-stage LFSO were 79.4 and 90.3%, respectively. The overall testicular atrophy rates of single- and two-stage LFSO were 17.3 and 11%, respectively. Fixed effect model analysis showed that two-stage LFSO is significantly superior to single-stage LFSO in overall success rate (odds ratio [OR: 2.57]; 95% confidence interval [CI]: 1.50-4.39, p = 0.0006) and testicular atrophy rate (OR: 0.48; 95% CI: 0.28-0.79, p = 0.004). There is no heterogeneity in the reports, and the funnel plot showed no publication bias.

Conclusions:  Two-stage LFSO remains the first choice of operation for children with a high IAT, with a significantly higher success rate and a lower testicular atrophy rate.

Objective:  This study aims to assess the histopathological characteristics of the fistulous tissue in males with anorectal malformation (ARM) to determine its suitability for use in constructing a neoanus.

Methods:  This prospective observational study included male ARM patients with recto-urethral fistula. All other types were excluded. The tissue specimens comprised 0.5 to 2.0 cm of the most distal part of the rectal pouch and the fistulous tissue. Hematoxylin and eosin-stained sections were prepared. Histological features, viz. internal sphincter, anal grand and crypts, ganglion cells, presence of subepithelial fibrosis, thickened nerve trunks, and metaplasia, were evaluated.

Results:  Of 65 patients of ARM admitted, 24 met the inclusion criteria. Gross and microscopic internal sphincter was not found in any sample. The anal mucosa was visualized in all samples; however, crypts were irregular and distorted architecture was seen in 4 (16.67%) samples. Urothelial metaplasia was identified in 10 (41.67%) samples. Adequate ganglion cells were seen only in 6 (25%) samples. Significant submucosal fibrosis was seen in all samples. Thickened nerve trunks were identified in 4 (16.67%) samples.

Conclusions:  All normal anal histological features could not be found together in the fistula tissue. With the absence of normal features, such as internal anal sphincter muscles, and the presence of abnormal histopathological features, such as subepithelial fibrosis, thickened nerve trunks, and metaplasia, there are high chances of abnormal bowel function like constipation if the fistulous tissue is used for neoanus construction. It may have an impact on the quality of life of patients.

Aim of the study:  Both Poland syndrome (PS) and tuberous breast (TB) are anomalies affecting the breast, but they are considered mutually exclusive. Our aim was to determine the possible coexistence of PS and TB and to discuss TB management when associated with PS.

Methods:  Between 2010 and 2023, 51 female adolescent PS patients were studied at our center. Among these, we evaluated those who developed TB after puberty. PS diagnosis was made based on the hypoplasia or absence of pectoralis major muscle detected clinically and confirmed radiologically. Breast anomaly on PS side was classified with Thorax Breast and Nipple (TBN) classification: B1 corresponds to breast hypoplasia, B2 to breast aplasia. TB diagnosis was made with a clinical evaluation after puberty. TB cases were classified according to Grolleau classification.

Main results:  Among 51 postpubertal PS females, we identified 23 (45%) who developed TB. In 3 cases (13%) TB was bilateral, in 20 (87%) contralateral to PS affected side. Age at time of the first surgical procedure was 16 years. Patients were treated with breast implants, fat grafting, rigotomy, local flaps, or a combination of these. TB treatment was performed simultaneously with PS breast reconstruction when feasible, or after it.

Conclusions:  TB incidence in our series was almost twice than in general population. This is the first study demonstrating and quantifying this association. TB deformity must be considered while defining PS surgical path in adolescents. Fat grafting is the first surgical option to treat both anomalies. A multidisciplinary approach is needed to minimize number of surgeries and maximize cosmetic results.

Introduction:  Interferential current (IFC) has been studied in several clinical trials for the treatment of bowel motility disorders, most often in children. However, only moderate effects are reported, and in contrast to IFC, the so-called placebo application is indiscernible. The mechanisms and neuroanatomic points of action remain elusive. Therefore, this therapy remains being questioned.

Methods:  To gain objective experimental data about IFC stimulation, we examined this method ex vivo in an isolated perfused porcine rectum including the mesorectum. To elucidate the role of plexus nerve fibers and enteric ganglia, we performed IFC stimulation also in the presence of tetrodotoxin (TTX) or hexamethonium (HXN). We applied the commonly used stimulation modes with a beat frequency sweeping between 5 and 25 Hz (IFC_d5-25) and 80 and 150 Hz (IFC_d80-150). We monitored intraluminal pressure and motility by online barometry and video recording, respectively. Motor activity, reflected by changes in the intraluminal pressure (cm H₂O·s^-1) and longitudinal movements (pixels·s^-1), was quantified over time as root mean squares (RMSs).

Results:  After IFC_d5-25, we observed a 30% increase in the rectal motility in the pressure changes which was sustained over 30 minutes post-stimulation (p < 0.02); only a minor effect was detected for IFC_d80-150. Both TTX and HTX abolished the stimulation. This suggests neuronal modulation.

Conclusion:  IFC_d5-25 stimulates rectal motor activity in the isolated perfused porcine rectum. Ganglia in the enteric nervous system are modulated to allow increased activity for at least 30 minutes. Therefore, the isolated porcine rectum is a suitable tool to study the effectiveness of various IFC settings in the rectum.

Introduction:  In the era of scientific digitalization, online media platforms gain increasing popularity to accomplish research output awareness. The Altmetric Attention Score AAS weights these online mentions based on a privy algorithm. We aimed to characterize the top 100 articles with the highest (AAS) published in pediatric surgery journals.

Materials and methods:  Publications from six core pediatric surgery journals were retrieved from www.altmetric.com in January 2023 and ranked by their AAS. The top 101 publications were analyzed for their bibliometric measures, study design, and quality as well as online media mentions.

Results:  The top 101 AAS articles were published between 1974 and 2022, preferentially from the United States (64%) and mainly in Journal of Pediatric Surgery (73%), followed by Journal of Pediatric Surgery Case Reports, Pediatric Surgery International, Seminars in Pediatric Surgery, and European Journal of Pediatric Surgery. Their AAS ranged between 21 and 389 (median: 33), with Twitter/X being mostly responsible for online mentions (n = 2,189; 75%). The number of citations in peer-reviewed journals ranged between 0 and 358 (median: 16) and did not correlate to AAS. Retrospective study design (33%) with low evidence level IV (43%) dominated.

Conclusion:  The Journal of Pediatric Surgery is the main source of high-profile AAS publications in pediatric surgery. The altmetric popularity of articles is predominantly achieved by their propagation via X, irrespective of the study quality and recognition in the scientific community. Thus, active "twitterism" may play the key role to reach high AAS scores.
