Background: Pediatric minimally invasive surgery (MIS) is a standard technique worldwide. We aimed to analyze the research activity in this field. Methods: Articles on pediatric MIS (1991–2020) were analyzed from the Web of Science™ for the total number of publications, citations, journals, and impact factors (IF). Of these, the 50 most cited publications were evaluated in detail and classified according to the level of evidence (i.e., study design) and topic (i.e., surgical procedure). Results: In total, 4464 publications and 53,111 citations from 684 journals on pediatric MIS were identified. The 50 most cited papers were published from 32 institutions in the USA/Canada (n = 28), Europe (n = 19), and Asia (n = 3) in 12 journals. Four authors (USA/Europe) contributed to 26% of the 50 most cited papers as first/senior author. Hot topics were laparoscopic pyeloplasty (n = 9), inguinal hernia repair (n = 7), appendectomy, and pyloromyotomy (n = 4 each). The majority of publications were retrospective studies (n = 33) and case reports (n = 6) (IF 5.2 ± 3.2; impact index 16.5 ± 6.4; citations 125 ± 39.4). They were cited as often as articles with high evidence levels (meta-analyses, n = 2; randomized controlled trials, n = 7; prospective studies, n = 2) (IF 12.9 ± 22.5; impact index 14.0 ± 6.5; citations 125 ± 34.7; p > 0.05). Conclusions: Publications on laparoscopic pyeloplasty, inguinal hernia repair, appendectomy, and pyloromyotomy are cited most often in pediatric MIS. However, the relevant number of studies with strong evidence for the advantages of MIS in pediatric surgery is missing.

Introduction Research on esophageal atresia (EA) has been heavily published over the past decades. Herein, we aimed to study the quantity and quality as well as key topics in EA research with regards to global collaborations among countries and authors. Material and Methods Publications on EA from 1945 to 2018 were extracted from the Web of Science core collection database. Productivity (quantity) was assessed by the number of publications. Quality was estimated from the number of citations, citation rate per item and year, h-index, and impact index. Collaborative networks were evaluated using VOSviewer. All measures were analyzed for countries, authors, and journals. The 10 most cited original articles between 1969 and 2018 in 5-year intervals (n = 100) were manually screened to assess the key points of EA research. Results A total of 2,170 publications from 85 countries published in 388 journals were identified yielding 26,755 citations, both significantly increasing over time (p < 0.001). The most productive countries and authors also accounted for high-quality publications and benefited from an active global network. The most productive journals derived from the field of pediatric surgery but accounted only for one-third of EA papers. The best cited journals were unspecific for pediatric surgery. Long-term outcome remained the most important topic in EA research, followed by surgical techniques, epidemiology, associated anomalies, perioperative complications, and postnatal management. In contrast, basic science was underrepresented. Conclusion Over the past seven decades, EA publications increased tremendously. Productiveness and quality benefited from global networking. Long-term outcome remains the key interest of EA research. ∗ Both the authors equally contributed to this article.
Purpose: Anorectal malformations (ARM) are one of the most challenging congenital malformations in pediatric surgery. We aimed to assess the research activity on ARM over the last five decades. Methods: Data on original research publications were retrieved from the Web of Science Core Collection (1970–2020), and analyzed for countries, authors, scientific journals, and top-ten papers. Scientific quantity was assessed by the number of publications. Research quality was estimated from the number of citations, average citation rate per item (ACI), and h-index. Results: A total number of 1595 articles with 19,419 citations (ACI = 12.2; h-index = 54) were identified. The annual number of publications and citations significantly increased over time (p < 0.0001). The USA (n = 386; 24.2%), Japan (n = 153; 9.6%), and China (n = 137; 8.6%) were the most productive countries; and the USA (n = 7850; ACI = 20.3; h-index = 44), Japan (n = 1937; ACI = 12.6; h-index = 21), and the Netherlands (n = 1318; ACI = 17.3; h-index = 22) were the top cited countries. Articles were preferentially published in JPS (n = 391; 24.5%), PSI (n = 181; 11.3%), and EJPS (n = 56; 3.5%). Top-ten cited papers focused on classification (n = 1), surgical technique (n = 3), associated syndromes (n = 2), postoperative outcome (n = 3), and basic research (n = 1). Conclusion: This bibliometric study provides valuable insights into the global development of ARM research, and shows that clinical studies and international collaborations dominate in this field.

An effective case report delivers clear and valuable clinical or surgical information to the medical community. Case reports dealing with pediatric surgical issues raise the medical community's awareness of rare diseases, unusual presentations of common disorders, or novel surgical or nonsurgical treatment approaches. Thus, case reports contribute substantially to medical advance by sharing remarkable or unexpected findings. For this reason, case reports should be prepared with vigilance, and current conventions on good medial writing practice should be observed. This guideline aims to assist clinicians and surgeons in the successful publishing of a compelling case report in pediatric surgery that is read and understood by the intended audience.
Background: Ovarian torsion (OT) is a rare but urgent surgical condition in children and adolescents. Evidence on how management differs between pediatric (PD) and non-pediatric (Non-PD) departments in Germany remains limited. Methods: We conducted a retrospective cohort study using anonymized claims data from two major German statutory health insurance funds (2010–2019), covering 6.3 million insured individuals (≈1 million children). Patients ≤18 years with an inpatient diagnosis of OT (ICD-10-GM N83.5) were analyzed with respect to demographics, department type (PD vs. Non-PD), hospital type (university/maximum care [UM] vs. non-university/maximum care [Non-UM]), surgical procedures, and outcomes. Results: A total of 293 patients (mean age 12.4 ± 4.5 years) were included; 71% were adolescents (12–18 years). Adolescents were predominantly treated in Non-PD (89%), whereas younger children were more often managed in PD (50%; p < 0.0001). Most cases were treated in Non-UM (82%). Laparoscopy was more commonly used in Non-PD departments (85%), while open surgery and oophorectomy occurred more frequently in PD and university hospitals (UM). Ovary-sparing procedures accounted for 77% of all cases, whereas 23% underwent oophorectomy. Mean hospital stay was longer in PD (6.7 ± 9.0 days) than in Non-PD (4.9 ± 2.2 days; p = 0.0167). Readmission rates were comparable across groups. Conclusions: Management of OT in Germany varies markedly by department and hospital type. PD and UM treat more younger patients but perform oophorectomy more frequently, whereas Non-PD and Non-UM favor laparoscopic, ovary-sparing strategies. These differences highlight the urgent need for standardized, evidence-based protocols prioritizing ovarian preservation and optimizing long-term outcomes in affected children and adolescents.
