Minimally invasive surgery (MIS) has revolutionized pediatric surgical care by
offering reduced trauma, faster recovery, and improved aesthetic outcomes compared
to open procedures. This study explores recent advancements in laparoscopic and
robotic surgeries in children, focusing on their clinical effectiveness, challenges, and
statistical outcomes. A retrospective review of 4,240 pediatric cases revealed that while
laparoscopy remains the predominant technique, robotic surgery is gaining traction due
to its superior precision and ergonomic advantages. Despite longer operative times and
higher costs, robotic-assisted procedures demonstrated lower complication rates,
reduced postoperative pain, and greater parental satisfaction. These findings
underscore the growing role of robotic surgery in complex pediatric cases and highlight
the need for continued innovation and training in minimally invasive techniques.

Introduction.
Minimally invasive surgery (MIS) has significantly transformed
the field of pediatric surgery over the past few decades. The introduction of
laparoscopic techniques in children marked a major milestone in reducing surgical
trauma, postoperative pain, and recovery time, while improving cosmetic outcomes.
More recently, robotic-assisted surgery has emerged as a cutting-edge approach,
offering enhanced dexterity, three-dimensional visualization, and greater precision—
features particularly valuable in complex pediatric cases.
While the advantages of MIS are well-documented in adult populations, its
application in children presents unique challenges. Pediatric patients have smaller
anatomical spaces, requiring highly specialized instruments and techniques.
Additionally, the high cost and limited availability of robotic systems, coupled with the
need for extensive training, have restricted their widespread adoption in pediatric
surgical practice.
Nevertheless, there has been growing interest in integrating robotic platforms into
pediatric surgery, especially for procedures that demand meticulous dissection and
suturing, such as pyeloplasty and fundoplication. Comparative studies between

laparoscopic and robotic approaches in children are still limited, and further research
is needed to assess their relative benefits and limitations.
This study aims to evaluate current advancements in laparoscopic and robotic
surgeries in pediatric populations. By analyzing a large cohort of surgical cases across
multiple centers, we explore the clinical outcomes, benefits, and challenges associated
with each technique, providing updated insights into their roles in modern pediatric
surgical care.
Materials and methods.
This retrospective, multicenter study was conducted to
evaluate the outcomes of minimally invasive surgical techniques—specifically
laparoscopic and robotic-assisted procedures—in pediatric patients. The study
included data collected from five high-volume pediatric surgical centers located across
Europe and Asia. Institutional review board (IRB) approval was obtained at each
participating center, and the study adhered to the ethical standards of the Declaration
of Helsinki.
The patient population consisted of children aged from newborn to 18 years who
underwent either laparoscopic or robotic surgery between January 2017 and December
2023. Inclusion criteria encompassed common pediatric surgical procedures where
both laparoscopic and robotic approaches were routinely utilized, including
appendectomy,
cholecystectomy,
pyeloplasty,
hernia
repair,
and
Nissen
fundoplication. Patients with incomplete medical records or who underwent
emergency open surgery without a minimally invasive attempt were excluded from the
analysis.
Data were extracted from electronic medical records and operative reports, and
included demographic information (age, sex, weight), type of procedure performed,
surgical technique used (laparoscopic or robotic), duration of the operation (measured
from skin incision to closure), intraoperative complications, and any conversions to
open surgery. Postoperative outcomes were also recorded, including length of hospital
stay, pain scores assessed using age-appropriate pediatric pain scales (e.g., FLACC,
Wong-Baker Faces), time to return to oral intake, and time to full recovery. Parental
satisfaction was assessed through a standardized survey administered upon discharge
and at follow-up.
Economic analysis was performed to estimate the average cost of each procedure
type, including operative expenses, equipment use, and postoperative care. Where
applicable, hospital billing records were used to determine the direct costs associated
with each surgical method.
All statistical analyses were conducted using SPSS software (version 27.0; IBM
Corp., Armonk, NY, USA). Descriptive statistics were used to summarize baseline
characteristics. Continuous variables were expressed as means with standard
deviations, while categorical variables were presented as frequencies and percentages.

Comparative analyses between laparoscopic and robotic surgery groups were
performed using independent t-tests for continuous variables and chi-square or Fisher’s
exact tests for categorical variables. Statistical significance was defined as a p-value of
less than 0.05.
The aim of this methodology was to provide a comprehensive comparison of the
two minimally invasive surgical modalities in pediatric populations across multiple
institutions, reflecting real-world practices and outcomes. This approach allowed for
the evaluation of not only clinical effectiveness and safety, but also logistical and
economic feasibility, which are critical when considering broader implementation of
advanced technologies such as robotic systems in pediatric surgery.
Results.
A total of 4,240 pediatric patients were included in the final analysis,
with 3,214 (75.8%) undergoing laparoscopic procedures and 1,026 (24.2%)
undergoing robotic-assisted surgeries. The age range of the patients was from 2 months
to 17 years, with a mean age of 8.6 ± 4.3 years. The overall male-to-female ratio was
approximately 1.2:1. The most commonly performed procedures across both groups
were appendectomy (28.3%), pyeloplasty (22.5%), cholecystectomy (18.1%), hernia
repair (15.9%), and Nissen fundoplication (11.4%).
Operative time differed significantly between the two surgical techniques. The
mean operative time for laparoscopic procedures was 68.4 ± 15.2 minutes, while
robotic-assisted surgeries took longer on average, with a mean duration of 84.1 ± 17.6
minutes (p < 0.01). Despite the longer duration, robotic procedures demonstrated a
lower rate of intraoperative complications. In the robotic group, intraoperative
complications occurred in 2.6% of cases, compared to 4.1% in the laparoscopic group
(p = 0.04). The rate of conversion to open surgery was also lower in the robotic group
at 1.7%, compared to 3.2% in the laparoscopic cohort (p = 0.03).
Postoperative outcomes favored robotic surgery in several domains. The average
length of hospital stay for robotic patients was 2.5 ± 1.1 days, compared to 2.9 ± 1.3
days in the laparoscopic group (p = 0.04). Pain levels, assessed using standardized
pediatric pain scales 24 hours after surgery, were also significantly lower in the robotic
group, with a mean pain score of 2.7 out of 10, compared to 3.4 in the laparoscopic
group (p < 0.05). Additionally, robotic surgery patients resumed oral intake and
returned to normal activity slightly faster, although these differences were not
statistically significant.
Parental satisfaction was assessed at discharge and follow-up using a 5-point
Likert scale, with scores converted into percentage satisfaction levels. In the
laparoscopic group, 87% of parents reported being “very satisfied” or “satisfied” with
the procedure and postoperative care, while this percentage rose to 93% in the robotic
group. Notably, parents cited reduced scarring, quicker recovery, and better pain
control as key factors contributing to their satisfaction with robotic surgery.

However, cost analysis revealed a substantial difference between the two
modalities. Robotic procedures were, on average, 2.2 times more expensive than their
laparoscopic counterparts. The increased cost was attributed to the robotic system's
maintenance, disposable instruments, and longer operating room usage. While the
higher cost limited the routine use of robotic surgery in some centers, in institutions
with established robotic programs, the technology was increasingly being used for
complex procedures such as pyeloplasty and redo surgeries, where its benefits in terms
of precision and visualization were most apparent.
Overall, the results demonstrate that while robotic surgery may not yet be the
standard for all pediatric minimally invasive procedures, it offers tangible advantages
in selected cases. Its favorable outcomes in terms of reduced complications, better pain
management, and higher satisfaction support its growing integration into pediatric
surgical practice, provided that financial and logistical challenges can be addressed.
Conclusions.
The findings of this multicenter study highlight the significant
progress and growing potential of minimally invasive techniques in pediatric surgery.
Laparoscopic surgery remains the most widely used approach due to its effectiveness,
safety, and accessibility. However, robotic-assisted surgery is emerging as a valuable
alternative, particularly in complex and delicate procedures where enhanced precision,
superior visualization, and greater instrument dexterity offer clear clinical advantages.
Despite longer operative times and higher costs, robotic surgery demonstrated
lower rates of intraoperative complications, reduced postoperative pain, shorter
hospital stays, and higher parental satisfaction. These benefits suggest that, when
available and economically feasible, robotic-assisted techniques may improve surgical
outcomes and the overall patient and family experience.
Nevertheless, limitations such as high financial burden, limited pediatric-sized
instruments, and the need for specialized training continue to challenge the broader
implementation of robotic systems in pediatric care. Future efforts should focus on
expanding access to robotic platforms, developing pediatric-specific technology, and
conducting long-term, prospective studies to further validate their advantages.
In conclusion, both laparoscopic and robotic approaches have distinct strengths,
and the choice of technique should be guided by the patient’s condition, surgical
complexity, available resources, and institutional expertise. As technology continues
to evolve, minimally invasive surgery will likely remain at the forefront of innovation
in pediatric surgical care.
