RESUMEN
Background: Robot-assisted pyeloplasty is the most frequently performed robotic procedure in children. A retroperitoneal approach limits surgical trauma and avoids peritoneal irritation. This led to the establishment of the criteria for day surgery (DS) and a related clinical care pathway. Objective: To assess the feasibility and safety of DS in children undergoing retroperitoneal robot-assisted laparoscopic pyeloplasty (R-RALP). Design setting and participants: We performed a bicentric prospective study (NCT03274050) over 2 yr involving the two major paediatric urology teaching hospitals in Paris. A clinical pathway and a prospective research protocol were specifically established. Intervention: DS in selected children undergoing R-RALP. Outcome measurements and statistical analysis: The primary outcomes were DS failure, 30-d complications, and readmission rates. The secondary outcomes included preoperative characteristics, perioperative parameters, and surgical outcomes. Quantitative variables were expressed as medians with interquartile ranges. Results and limitations: Thirty-two children fulfilled specific inclusion criteria and were consecutively selected for DS following R-RALP. The median patient age was 7.6 yr (4.1-11.8) and weight 25 kg (14-45). The median console time was 137 min (108-167). There were no intraoperative complications or conversions. Six children were kept under observation overnight and discharged the following day due to persistent pain (n = 3), parental anxiety (n = 2), or a prolonged procedure (n = 1). The median duration of hospital stay of the 26 children in the DS setting was 12.7 h (12.2-13.2). During the 30-d period, there were four emergency room visits (15%) resulting in two patients requiring readmission (8%): one for febrile urinary tract infection (Clavien-Dindo II) and one child with no JJ stent for urinoma (Clavien-Dindo IIIb). Radiological studies confirmed improvement in dilatation for all cases with no recurrence (median follow-up: 15 mo). Conclusions: This prospective case series is the first to demonstrate the feasibility and safety of DS in children undergoing R-RALP, obviating the need for routine inpatient care. Excellent results can be achieved by careful patient selection, a clear clinical pathway, and a dedicated team. Further evaluation is warranted to assess the cost effectiveness. Patient summary: This study shows that day surgery after robotic pyeloplasty is both safe and effective in selected children.
RESUMEN
OBJECTIVE: To report one-year morbidity of robotic-assisted laparoscopic surgery (RALS) in a dedicated, multidisciplinary, pediatric robotic surgery program. Summary Background Data. RALS in pediatric surgery is expanding, but data on morbidity in children is limited. METHODS: All children who underwent RALS (Da Vinci Xi, Intuitive Surgical, USA) were prospectively included (October 2016 to May 2020; follow-up ≥1 year). Analyzed data: patient characteristics, surgical indication/procedure, intraoperative adverse events (ClassIntra classification), blood transfusion, hospital stay, postoperative complications (Clavien-Dindo). RESULTS: Three hundred consecutive surgeries were included: urology/gynecology (n=105), digestive surgery (n=83), oncology (n=66), ENT surgery (n=28), thoracic surgery (n=18). Median age and weight at surgery were 9.5 [interquartile range (IQR)=8.8] years and 31 [IQR=29.3] kg, respectively. Over one year, 65 (22%) children presented with ≥1 complication, with Clavien-Dindo ≥III in 14/300 (5%) children at ≤30 days, 7/300 (2%) at 30-90 days, and 12/300 (4%) at >90 days. Perioperative transfusion was necessary in 15 (5%) children, mostly oncological (n=8). Eight (3%) robotic malfunctions were noted, one leading to conversion (laparotomy). Overall conversion rate was 4%. ASA ≥3, weight ≤15 kg, and surgical oncology did not significantly increase the conversion rate, complications, or intraoperative adverse events (ClassIntra ≥2). ASA score was significantly higher in children with complications (Clavien-Dindo ≥III) than without (p=0.01). Median hospital stay was 2 [IQR=3] days. Three children died after a median follow-up of 20 [IQR=16] months. CONCLUSIONS: RALS is safe, even in the most vulnerable children with a wide scope of indications, age, and weight. Robot-specific complications or malfunctions are scarce.
