[Dysphagia treatment in a clinical-geriatric setting PEG and functional therapy of dysphagia].

OBJECTIVES

Patients with dysphagia whose food intake is inadequate and who may compromise their airways need to receive nasogastric (NG) or gastrostomic (PEG) feeding. There are controversial discussions about the best time for intervention and the best method. Each approach has its advantages and disadvantages. Further research is required to assess the optimum method of treating patients with dysphagia. A retrospective study was undertaken to investigate the influence of functional dysphagia therapy with or without PEG feeding.

METHODS

A total of 164 patients with dysphagia were investigated in a center for geriatric medicine (EGZB) within one year. Patients were divided into two groups: those with PEG (group 1, n=59) and those without (group 2, n=105). Both groups received functional training (training of oral motor skills and sensation, compensatory swallowing techniques) by speech-language therapists.Geriatric basic assessment was used. Speech-language therapists also evaluated language, speech and swallowing disorders pre- and post-training. Diet modification for oral intake altering viscosity and texture of foods and liquids was used. Additional data on the time between being admitted to hospital and receiving a PEG tube, the hospitalization period, the number of complications and mortality were collected.

RESULTS

Both groups benefited from functional dysphagia therapy. The patients of group 2 showed a significant improvement in functional oral intake post-treatment. In most of the cases, diet modification improved from pasty consistency to firm meals. Swallowing abilities were much better than those of the more severely disabled patients of group 1. Group 1 still needed PEG feeding post-treatment but could also take in some food orally. However even the patients of group 1 showed a significant increase in functional oral intake.Group 2 also showed significantly stronger improvements in communication abilities and speech intelligibility after training compared to the severely disabled patients of group 1.In terms of the clinical outcome of group 1 it was demonstrated that the sooner a PEG was placed, the more significantly functional oral intake improved. The results of a multiple regression analysis showed a small but nevertheless significant association between an early supply of PEG and improvement of functional oral intake which had been achieved by functional dysphagia therapy.Significantly more complications and significantly higher mortality occurred in group 1 (PEG feeding) compared to group 2 (exclusively oral feeding).

CONCLUSION

The treatment of dysphagia in the elderly requires a multi-professional setting, differentiated assessment and functional training of oral motor skills and sensation and swallowing techniques. Compared to patients with severe dysphagia, however, patients with mild to moderate dysphagia benefit most from functional training. The results reveal the importance of precise and early diagnosis of swallowing disorders in order to introduce PEG supply early in cases of persistent dysphagia.
