ABSTRACT
Robotic pyeloplasty has become a technique of choice for pyelo-ureteral junction syndrome treatment in children. Less invasive than open surgery, robotic pyeloplasty also has a lower learning curve than laparoscopic pyeloplasty. This is how a new generation of surgeons without previous laparoscopic pyeloplasty experience has begun training in robotics. To assess the robotic assisted pyeloplasty learning curve for a pediatric surgeon only trained in open pyeloplasty, and to investigate if that mode of practice is safe and effective. Data were collected from all children operated on for pyelo-ureteral junction syndrome by the same surgeon in our center between 2015 and 2021. Cases were divided into 4 groups of 14 consecutive procedures to analyze the learning curve. Fifty-six patients were operated on, with a median (IQR) age, weight, and hospital stay of 9 years and 1 month old (3.5), 29 kg (17.3), and 3 days (2), respectively. The mean ± SD operative times were 146.5 ± 39.3, 123.2 ± 48.1, 103.1 ± 29.5, and 141.7 ± 25.0 min, with a unique significant difference between groups 1 and 3 (p = 0.007**). Only two intraoperative and nine postoperative complications were observed. The surgery was successful in 98% cases. Our study shows that a significant improvement in surgical time could be achieved in the first 30 cases, safely and efficiently even without previous laparoscopic pyeloplasty experience.Level of evidence: III.

INTRODUCTION: Neonatal and infant anaesthesia are associated with a high risk of perioperative complications. The aim of the current study was to describe those risks in France using the French data from the NECTARINE study. MATERIAL AND METHODS: Data from the French centres that participated to the NECTARINE study were analysed. The primary goal of the study was the description of patients' characteristics, procedures and perioperative management and their comparison with the results of the European NECTARINE study. Secondary outcomes were the description of major perioperative complications and death. RESULTS: Overall, 926 procedures collected in 15 centres (all teaching hospitals) were analysed. Comparison between the French and European NECTARINE cohorts found few differences related to patients' characteristics and procedures. The rate of interventions for critical events (respiratory, haemodynamic, and metabolic) was similar between the two cohorts. Near-infrared spectroscopy monitoring was used in 12% of procedures. Nearly none of the thresholds for these interventions met the published standards. By day 30, complications (respiratory, haemodynamic, metabolic, renal, and liver failure) and death were observed in 14.4% [95% CI 11.6-16.4]% and 1.8% [95% CI 1.1-2.9] of cases, respectively. DISCUSSION: Although the health status of the patients in the French cohort was less severe, procedures, management and postoperative complications and mortality rates were similar to the European cohort. However, thresholds for interventions were often inadequate in both cohorts. Efforts should be undertaken to improve the knowledge and use of new monitoring devices in this population.
