[Problems in technical development of laparoscopy and thoracoscopy in infancy].

In neonates a new fixation of the trocars must be found since the umbilical ring is large and distensible and the abdominal wall is very thin. The pressure-controlled pneumoperitoneum is maintained by using a special "surgiflator" system which prevents high pressure peaks in the small abdominal cavity of neonates. By using a Nd:YAG laser for transection during coagulation an additional trocar can be dispensed with.
