Thoracoscopy - EmpyemaTechnique
• Three 10 mm incisions (triangle)
• Initial incision 4th or 5th ICS, AAL
• Use telescope to compress lung and create working space
• 2nd incision opposite 1st one, PAL
• 10 mm cannulas,insufflation to 6-8 torr 10 mm angled telescope

Thoracoscopy - EmpyemaTechnique
• 3rd incision (10 mm), 9th or 10th ICS, MAL
• Site for chest tube exteriorization

How To Get StartedNot The Ideal Case
• 2 - 2.5 kg
• Very high upper pouch
• Complex single ventricle physiology
• Prostaglandin dependent
![Page 38: Indications for thoracocoscopy in children brazil 2014](https://reader034.fdocuments.us/reader034/viewer/2022042817/559d14241a28abdf018b46df/html5/thumbnails/38.jpg)
How To Get StartedIdeal Case
• Baby – 2.5-3 kg; no other anomalies
• Esophageal segments close together (CXR, Bronchoscopy)
• Start thoracoscopically – Go as far as comfortable
• Try it again
![Page 39: Indications for thoracocoscopy in children brazil 2014](https://reader034.fdocuments.us/reader034/viewer/2022042817/559d14241a28abdf018b46df/html5/thumbnails/39.jpg)
Summary• Thoracoscopy can
be done safely and effectively in infants and children
