   Objectives
 
After completing this article, readers should be able to:

  1. Review physiologic, anatomic, and technical issues related to minimal access surgery in the neonate.
  2. Describe conditions in which minimal access surgery can be used in neonates.


   Introduction
 
Historically, pediatric surgeons were slow to adapt to minimal access surgery (MAS) techniques compared with the adult surgical community. However, MAS now is widely established in infants and children. Differences in size and physiology have necessitated a number of surgical and technological modifications to apply MAS techniques to this population. This review outlines the important differences between children and adults with respect to MAS and provides examples of the use of MAS for diseases seen in infants.


   General Considerations for MAS in the Infant
 
     Physiologic Issues
The physiologic response to pneumoperitoneum in children is more pronounced than in adults. Peritoneal insufflation with carbon dioxide has been shown to cause hypercarbia, acidemia, and decreased oxygenation in the pediatric piglet model. (1) In infants, however, there is no detrimental effect on blood pressure, heart rate, or oxygen saturation during short periods of pneumoperitoneum, and elevations in end-tidal CO2 can be counteracted readily by increasing the minute ventilation. (2) Hypercarbia-induced pneumoperitoneum in infants is associated with changes in cerebral blood flow and cardiac output. Nevertheless, laparoscopic procedures have been performed safely with proper anesthetic management in children who have even severe congenital cardiac abnormalities such as hypoplastic left heart syndrome. (3) Hypothermia also can be a concern due to rapid insufflation of unwarmed CO2 gas, mandating the moderation of flow rates. (4)

     Anatomic Issues
A number of anatomic factors set children apart from adults and must be accounted for when performing laparoscopic surgery in this age group. Young children and infants have thinner abdominal walls than adults, so extreme care must be exercised when placing trocars. Due to the small size . . . [Full Text of this Article]
