Swallowing Rehabilitation Affects Period of Hospitalization after Surgery for Tongue Cancer.

Functional rehabilitation has been reported to improve swallowing. The effect of the presence or absence of such rehabilitation has yet to be compared in oral cancer patients, however. The purpose of this study was to investigate its effect on correlations between the period of hospitalization and the period of tube feeding (from the day of surgery to termination of tube feeding) and period of oral nutrition (from termination of tube feeding to discharge). Body weight was also measured on admission and discharge and the difference calculated. A correlation was observed between period of hospitalization and period of tube feeding in the rehabilitation group, and with the periods of tube feeding and oral nutrition in the non-rehabilitation group. In the rehabilitation group, the period of tube feeding appeared to affect period of hospitalization. On the other hand, termination of tube feeding did not tend to affect period of hospitalization. These results suggest that both periods were factors affecting period of hospitalization in the non-rehabilitation group. Not performing swallowing rehabilitation, therefore, resulted in the period of oral nutrition affecting the period of hospitalization. This suggests that it is essential that nutrients be ingested in moderation after termination of tube feeding, when they are only taken orally. Moreover, these results also indicate that rehabilitation is important in improving quality of life after discharge.
