Surgical Treatment of Broncholithiasis

I clinically analysed 13 cases of broncholithiasis which treated surgically and found only four cases of broncholithiasis caused by the erosion of the peribronchial lymph node named by extrinsic formation[Group II], and nine cases of broncholithiasis caused by intrinsic formation[group I] which indicates that no evidence of the erosion of the calcified per-ibronchial lymph node into the bronchial tree was found. This study is performed to see any differences between two groups regarding presenting symptoms, locations of broncholith, preoperative diagnosis, a history of pulmonary tuberculosis, a procedure of operation, and chemical compositions of broncholiths from both groups. There was no difference between two groups in the presenting symptoms, the procedure of operation, and chemical compositions of broncholiths. The broncholits from group two is located in the right middle lobe bronchus, and the broncholiths of group one were distributed at various bronchi, In group one, only five cases out of nine had preoperative diagnosis[55.5%], but in group two, all four had preoperative diagnosis. All cases had good postoperative courses without any complication and recurrences.
