심각한 뇌손상 환자의 난치성 흡인을 위한 후두기관분리술

초록

Laryngotracheal separation (LTS) is one of the treatment options for intractable aspiration. Here, we present two cases of LTS with successful prevention of intractable aspiration. The first case was a 60-year-old man with severe hypoxic brain damage caused by hydrogen sulfide (H2S) intoxication; he was admitted to our department for comprehensive rehabilitation. Frequent tracheal suction was required due to the excess secretion from saliva aspiration. Matters were complicated when he suffered frequent regurgitation and vomiting, which was followed by tracheal aspiration. In the second case, a 78-year-old man presented with a severe traumatic brain injury. He had experienced recurrent aspiration pneumonia, which was unresponsive to conventional therapy. In both cases, LTS was performed to prevent intractable aspiration pneumonia. Subsequent to the LTS procedure, videofluoroscopic swallowing study showed complete prevention of the aspiration in both patients. Moreover, tracheal secretion was reduced, and tracheal suction was no longer required. Post-surgery, there was no development of aspiration pneumonia during their hospital stays.
