How to decide which infant can have robotic surgery? Just do the math.

Area of Science:

• Pediatric Urology
• Minimally Invasive Surgery
• Surgical Robotics

Background:

• Robot-assisted surgery offers advantages over conventional laparoscopy in pediatric urology.
• Limited workspace in infants can impede robotic instrument mobility.
• Objective parameters for selecting infants for robotic surgery are lacking, especially for novice surgeons.

Purpose of the Study:

• To evaluate experience with infants undergoing robotic surgery.
• To establish objective standards for patient selection in infant robotic surgery.
• To identify predictive parameters for surgical success and safety.

Main Methods:

• Prospective evaluation of 45 infants (3-12 months) undergoing robotic intervention.
• Preoperative measurement of anterior superior iliac spine (ASIS) and puboxyphoid distance (PXD).
• Recording of robotic instrument collisions and console time during surgery.

Main Results:

• No significant differences in ASIS, PXD, collisions, or console time based on gender, age, or weight.
• Strong inverse relationship between ASIS/PXD and the number of instrument collisions.
• Fewer collisions observed with ASIS >13 cm and PXD >15 cm, correlating with reduced console time.

Conclusions:

• Careful patient selection is crucial for safe robotic surgery in infants.
• Increasing ASIS and PXD measurements correlate with fewer instrument collisions and shorter console times.
• ASIS and PXD measurements can guide novice surgeons in selecting infants for robotic procedures.
