Comparisons of results of 5 patients with coughing within 4 weeks and more than 1 year after undergoing a pulmonary resection procedure. The number of reflux occurrences was 236+/-136 in the patients within 4 weeks after the operation and 229+/-112 at more than 1 year after the operation (p = 0.9). The %pH <4.0 values were 18.7+/-16.8% within 4 weeks after the operation and 14.1+/-9.2% at more than 1 year after the operation (p = 0.6). The visual analog scale results were 4.8+/-1.3 within 4 weeks after the operation and 0.2+/-0.4 at more than 1 year after the operation (p < 0.0001). The numbers of coughing occurrences were 80.0+/-60.2 within 4 weeks after the operation and 4.2+/-7.8 at more than 1 year after the operation (p = 0.03).
