Successful Treatment of Carcinomatous CentralAirway Obstruction with Bronchoscopic Electrocautery UsingHot Biopsy Forceps during Mechanical Ventilation

Wereportthecaseofa72-year-old manwithocclusionoftheleftmainbronchusduetosquamouscellcarcinomaofthelung.He required tracheal intubation and mechanical ventilation because of the aggravation of atelectasis and obstructive pneumonia.Electrocautery using hot biopsy forceps was performed during mechanical ventilation with a 40% fraction of inspired oxygen.He was extubated following improvement in the atelectasis and obstructive pneumonia and discharged with shrinkage of thetumor after chemotherapy. We describe a safe electrocautery procedure using hot biopsy forceps during mechanical ventilationwith reference to previous reports.
