title: [Laryngotracheal separation and tracheoesophageal diversion for intractable aspiration in ALS--usefulness and indication].
abstract: To evaluate the usefulness of laryngotracheal separation or tracheoesophageal diversion (LTS/TED), we investigated changes in medical management after LTS/TED. We performed LTS/TED for intractable aspiration in patients with amyotrophic lateral sclerosis (ALS) and patients with other neurological diseases. Most of the subjects had already received a tracheostomy, and all the patients with ALS had tracheostomy positive pressure ventilation. However, they remained at risk of intractable aspiration, had experienced frequent suctioning of aspiration material, and could not eat. In all cases, LTS/TED was performed safely within 3 hours and without any complications. After LTS/TED, there was no aspiration of saliva in any of the patients. In most subjects, the frequency of suctioning by medical staff and caregivers was much reduced. The frequency of aspiration pneumonia was also extremely lowered. Follow-up study demonstrated that complete control over aspiration was achieved in all of the patients. Some of them were completely self-sufficient in their ability to eat. Some of the other patients were at least able to enjoy taste. Nutritional status was significantly improved. All the patients, family caregivers, and medical staff involved in this study were satisfied with the outcome. These results indicate that LTS/TED is a very useful procedure in several aspects: it benefits patients who have a fear of aspiration; it reduces the burden on patients and family caregivers; it promotes their quality of life; and it limits the aspiration-associated demands on medical staff. Based on the results, we have proposed an indication of LTS/TED for dysphasia in ALS.
