1. Bibliometric study in pediatric minimally invasive surgery (MIS)
Pediatric MIS is a standard technique worldwide for many pediatric surgical diseases and we aimed to analyze the research activity in this field. Articles on pediatric MIS (1991–2020) were analyzed from the Web of ScienceTM for the total number of publications, citations, journals, and IFs. 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). 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).
2. Altmetric study in pediatric surgery
Altmetric analysis assessing online mentions of publications is a new method to evaluate awareness to research output. We aimed to identify and characterize the top 100 articles with the highest Altmetric Attention Score (AAS) in pediatric surgery. Publications from core pediatric surgical journals (J Pediatr Surg, J Pediatr Surg Case Rep, Eur J Pediatr Surg, European J Pediatr Surg Rep, Pediatr Surg Int, Semin Pediatr Surg) were retrieved from www.altmetric.com in January 2023 and the top 100 publications were identified. Characteristics of each publication were analyzed. Publications ranked 93 to 101 had an identical AAS of 21. Thus, 101 articles were included for further analysis. The top 101 AAS articles were published between 1974 and 2022, preferentially from the United States (64%) and mainly in J Pediatr Surg (73%), followed by J Pediatr Surg Case Rep, Pediatr Surg Int, Semin Pediatr Surg, and Eur J Pediatr Surg. Their AAS ranged between 21 and 389 (median 33) with X (formerly Twitter) being mostly responsible for online mentions (n=2189, 75%). The number of citations ranged from 0 to 358 (median 16) and did not correlate with the AAS. Retrospective study design (33%) with low evidence level IV (49%) was the dominant study type.
3. Conclusions
According to our bibliometric study in pediatric MIS, research activity increased over the last 30 years, with a golden decade in the early 21st century. Laparoscopic pyeloplasty and inguinal hernia repair accounted for most of the top 50 citations. Retrospective studies and case reports were the most common type of publication. Studies with high level of evidence such as randomized controlled trials are missing, especially on advanced techniques in pediatric MIS.
For our altmetric study of publications in core pediatric surgery journals, we analyzed the top 101 most mentioned pediatric surgery articles in six pediatric journals. Among the pediatric surgical journals, the Journal of Pediatric Surgery is the main source for high-profile publications in pediatric surgery. The altmetric score of articles is predominantly achieved by their propagation via X (formerly Twitter), irrespective of study design, level of evidence or recognition by the scientific community. Therefore, active “twitterism” may play the key role in reaching high AAS.
