To clarify the indications and usefulness of Percutanous endoscopic gastrostomy (PEG) in patients with Silicosis and some co-morbidities, we analyzed eight cases of silicosis, who suffered from dysphagia and had received a PEG for tube feeding during the period from 1998 to 2002. The characteristics, and clinical course, of each case were statistically analyzed before and during PEG usage. All cases were bed-ridden males, with a mean age of 80 years. The profusion rate (PR) grade of silicosis was for five cases in category 2, and for three cases in category 4. Most of the co-morbidities were dementia (five cases), and chronic heart failure (four cases). There were no significant improvements in the measured nutrition criteria (albumin, lymphocytes) nor in respiratory function (arterial O2) between before and during PEG usage. Tube feeding through the PEG was not performed in three cases because of repeated aspiration pneumonia. The mean duration of PEG usage was 9 months, ranging from 5 to 20 months. Five cases died of the co-morbidities. Furthermore, there was significant deterioration in the bacteriological data (p=0.001), suggesting a worsening of the swallowing disturbances during PEG usage, or the emergence of more resistant organisms as a result of empirical antibiotic therapy. The present results suggest that the indications of PEG in cases of severe chronic obstructive pulmonary disease (COPD) such as silicosis, associated with other morbidities, and with dysphagia, are somewhat limited. The patient's general condition should be an important factor in deciding whether or not this technique should be used.
