Insights

Minimally invasive surgery (MIS) is safe and feasible in infants under 5 kg, with low complication rates. Advanced techniques and tools enable complex procedures, though intestinal anastomosis remains challenging.

Area of Science:

  • Pediatric Surgery
  • Minimally Invasive Surgery
  • Laparoscopic Procedures

Background:

  • Advancements in surgical skills and miniature laparoscopic tools have enabled endoscopic procedures in infants.
  • This study evaluates the experience with minimally invasive surgery (MIS) in infants weighing less than 5 kg.

Purpose of the Study:

  • To document the experience and outcomes of MIS in infants under 5 kg.
  • To assess the feasibility and safety of various laparoscopic and thoracoscopic procedures in neonates.

Main Methods:

  • Retrospective database review from September 1993 to September 2007.
  • Inclusion criteria: children weighing 5 kg or less undergoing laparoscopic or thoracoscopic procedures.

Main Results:

  • 649 cases performed, including 43 different procedures; Nissen fundoplication was most common (310 cases).
  • No surgery-related deaths; conversion rate to open surgery was 1.2% (8 cases).
  • Overall complication rate was 3% (20 cases), with an intraoperative complication rate of 0.9% (6 cases).

Conclusions:

  • Modern low-flow CO2 insufflators, smaller instruments, and advanced techniques make MIS in neonates feasible and safe.
  • Intestinal anastomosis in confined spaces presents the greatest challenge, requiring further technical advancements for universal adoption.
