BACKGROUND/ PURPOSE: Mediastinal masses commonly are referred to the pediatric surgeon and can be difficult diagnostic problems. Various techniques have been used to perform biopsy in the mediastinum, but there are few reports of mediastinoscopy or Chamberlain procedure in children in the literature. The authors reviewed their experience with these techniques in a pediatric oncology population. METHODS: The medical records of all patients on the pediatric surgical service between 1987 and 1997, inclusive, who underwent mediastinoscopy or Chamberlain procedure were reviewed. Demographic data, diagnostic accuracy, complications, operating time, and blood loss were recorded. RESULTS: Sixteen consecutive patients underwent 13 Chamberlain procedures and six mediastinoscopies over the above period. Diagnostic accuracy was found to be 95% overall (100% for Chamberlain procedure, 83% for mediastinoscopy). Five complications occurred in the Chamberlain group and none in the mediastinoscopy group. No complication required thoracotomy or sternotomy. Among patients whose sole reason for admission was diagnosis of a mediastinal mass, the mean hospital stay was 1.7+/-0.8 days (n = 7) for those who underwent Chamberlain procedure and 1.4+/-0.9 days (n = 4) for those who underwent mediastinoscopy. One mediastinoscopy was performed as an ambulatory procedure. CONCLUSION: Mediastinoscopy and the Chamberlain procedure are effective and safe techniques for biopsy of mediastinal masses in this age group.
