Percutaneous endoscopic gastrostomy (PEG) use is common in patients who undergo radiotherapy (RT) for head and neck cancer to maintain weight and nutrition during treatment. However, the true effect of PEG use on weight maintenance and its potential impact on long-term dysphagia outcomes have not been adequately studied. This retrospective study looked at swallowing-related outcomes among patients who received prophylactic PEG vs. those who did not, and among patients who maintained oral diets vs. partial oral diets vs. those who were nil per os (NPO). Outcomes were assessed at the end of RT and at 3, 6, and 12 months post RT. A comprehensive review of patients’ medical charts for a 6-year period yielded 59 subjects with complete data. Results showed no difference in long-term percent weight change between the prophylactic PEG patients vs. all others, or between patients who, during RT, had oral diets vs. partial oral diets vs. NPO. However, those who did not receive prophylactic PEGs and those who maintained an oral or a partial oral diet during RT had significantly better diet outcomes at all times post RT. Dependence on a PEG may lead to adverse swallowing ability in post-irradiated head and neck cancer patients possibly due to decreased use of the swallowing musculature.
This analysis suggests a preventive effect of oral care on pneumonia in nonventilated individuals. This effect, however, should be interpreted with caution due to risk of bias in the included trials.
Purpose
The purpose of this study was to compare the biomechanics of the effortful pitch glide (EPG) with swallowing using dynamic MRI. The EPG is a combination of a pitch glide and a pharyngeal squeeze maneuver for targeting laryngeal and pharyngeal muscles. The authors hypothesized that the EPG would elicit significantly greater structural excursions of anterior hyoid, superior hyoid, hyolaryngeal approximation, laryngeal elevation, and lateral pharyngeal wall medialization compared with swallowing.
Method
Eleven healthy, young subjects with a mean age of 25 were recruited. The EPG was first taught and verified via laryngoscopy. Then 2-planar (coronal and sagittal) dynamic MRI acquisitions captured 10 repeated swallows and 3 EPGs. Kinematic analyses of minimum and maximum excursion of anatomical landmarks were calculated.
Results
Results showed a nonsignificant difference between the 2 tasks for range of excursion with all measured biomechanics except for superior hyoid, where the swallow showed significantly greater excursion. This indicated that swallowing and EPG biomechanics were comparable, lending support for the potential use of the EPG as another nonswallowing exercise.
Conclusion
Findings suggest EPG may be an effective exercise to target several important swallowing muscles, especially the long pharyngeal muscles that elevate the larynx and shorten the pharynx in swallowing.
