Meanwhile, the results after performing bronchial reconstruction were good and enlar-     ging the operative indication of bronchoplastic procedure was recommendable for preservation      of pulmonary function and for obtaining of extended resection and the operative indication      of bronchial reconstruction should be extend to the treatment for cicatric stenosis, bronchial       adenoma and traumatic rupture.                    INTRODUCTION       The prognosis of tracheal reconstruction was extremely poor compared with that of bronchial reconstruction.      Several factors associated with increased risk for surgery are as follows. 1) preoperative poor condition with dyspnes and cyanosis. 2) technical difficulty of respiratory care during operation. 3) complexity of reconstructive procedures due to the wide extent of stenotic lesion. 4) the high incidence of postoperative complications resulted in death.      The development of tracheal surgery might be achieve to overcome these clinical troubles.       The patients undergone reconstructive operation of tracheobronchial tree are incre-asing in number with the improvement of surgical technique, the establishment of safety repiratory care during operation and enlarging the indication of surgical treatment.      More recently the operative indication seems to select for the traumatic injuries, cicatric stenosis and benign or malignant tumor of the tracheobronchial tree. However, the recnstructive techniques are directly associated with threat to life.      The surgical indication, therefore, should be determined carefully in patient with a disorders of tracheobronchial tree. The aim of the present study was to certify the clinical difference between tracheal and bronchial diseases to enlarge the widespread application clinically.                 CLINICAL MATERIAL      Thirty-seven patients underwent operative treatment for disorders of tracheobronchia trees, 12 out of them had tracheal reconstruction and the remaining 25 had bronchial reconstruction as shown in table 1.      Male is affected predominantly rather than femals and age varys from 16 to 69 years.      In the aged group, the etiology of these lesions are chiefly malignant disease which is demonstrated as cancerous invasion into the trachea and the bronchus from bronchogenic carcinoma and thyroid cancer, whereas traumatic injuries are main lesion in the young.      According to the severity of traffic accident, there are many chances to encounter in the patients with bronchial rupture by blunt chest trauma. we have the experience in 2 cases with traumatic injuries.      They had in all 2 cases shortness of breath, bloody sputum with pneumothorax and                 Table 1 . Cases undergoing tracheobronchial reconstruction     Disease cases with cases with                                                        trachal surgery bronchil surgery Traumatic direct suture 1  rupture sleeve 1 Cicative sleeve 1 1  stnosis wedge 1             patch 1Malignant terminal tracheostomy 4  Disease patch 1 2             sleeve 1 13            replacement by artificial trachea 1             wedge 6 Bronchial sleeve 1  adenoma wedge 1 1                                                12 25subcutaneous emphysema in cervical region. Such a Ventilatory failure was characterized as the severity out of proportion to the degree of traumatic injuries on thoracic wall.       Of 4 cases with cicatric stenosis, 3 cases had tracheal stenosis, 1 case had a exten-sive stenotic lesion in length from the upper portion of the intrathoracic trachea to bilate-ral main bronchus involving tracheal bifurication, the other 2 cases showed segmental ste-nosis arising from tuberculous inflammation and mechanical irritation by endotracheal catheter tip.      Of 3 cases with bronchial adenoma, one had tracheal stenosis by adenoid cystic carcinoma and the remaining 2 cases had stenosis of right main bronchus by carcinoid type and mucoepdermoid tumor respectivelly.      Of 28 out of 37 cases, the etiology of producing stenotic lesion were malignant disease in which 4 cases had thyroid cancer, 1 esophageal carcinoma, 23 lung cancer respectivelly.      Of 37 cases with reconstructive surgery of tracheobronchial tree, tracheal reconstruction was carried out in remaining 12 cases although bronchial reconstruction was performed in 25 cases                      RESULTS      The affected location of the tracheobronchial tree were shown in Fig 1. The lesion in cervical trachea were seen in 5 cases and one of these 5 cases had traumatic injuries and the remaining 4 cases had cancerous invasion from thyroid cancer.      In one patients with tracheal recostruction in thoracic region artificial tracheal substi-tute is necessary to achieve an adequate reconstruction for extensive defect in length after resection for cicatric stenosis.Fig 1. The numbers of cases with reconstructive surgery        and the affected location of tracheobronchial tree     Silastic tube in this case was utilized as the substitute of the trachea after removal of stenotic lesion in almost entirely length of intrathoracic trachea including bilateral main bronchus and the carina.      However, its prognosis was poor and died at 8 hours after surgery of bleeding diathesis and postperfusion lung syndrome provoked prolonged extracorporeal circulation time of about 4 hours which was necessary to support perioperative respiration due to tracheal stenosis. One with cicatric stenosis of the trachea had a satisfactory result by patch method with pericardium and the remaining one with tracheal stenosis following tracheostomy had rec-urrence of stenosis sequent to reconstructive surgery. All of them died of postoperative pul-monary complication. From these results, it seems to be partly associated with denervation of the lung after reconstructive procedures. An attempt to advanced tracheal surgery, there-fore, appears to be in effect to prevent pulmonary complication postoperativelly.      Of 25 cases treated with bronchial reconstruction, 24 cases had bronchoplastic procedures performed for the main bronchus. The remaining one had reconstructive plasty for the right middle truncus. None of them had postoperative death and its prognosis were excellent except one death by anastomosis insufficiency due to frequently endotracheal aspiration pro-cedures to alleviate aspiration pneumonia although 7 cases had postoperative complication in which pulmonary complication were seen in 3 cases, pyothorax in 1, liver dysfunction in 1, anastomotic stenosis in 1      The clinical differences in patients with surgery of tracheal and bronchial reconstruction were analyzed in several factors as shown in Table 2.  The significant differences with regard to sex and age distribution are found out in                      Table 2.

The etiology of occuring tracheal lesion were essentially same as that of bronchial lesion. The most predominant difference consists in preoperative symptoms, that is, the chief complai ns were wheezing and bloody sputum in those whom tracheal surgery was performed whereas no severe respiratory symptomes such as cough and sputum complained in those with bronch-ial surgery.      The preoperative condition was extremely poor in those who having a tracheal reconstru-ction due to severe respiratory distress compared with those who having a bronchial reconst-ruction.      Postoperative complications occured in 6 cases with tracheal surgery and in 7 cases with bronchial surgery as shown in Table 2. The most of them were demonstrated as pul-monary complication owing to infection.      The incidence of postoperative complication in those patients with tracheal surgery was the same in those with bronchial surgery.      However, the postopetative complication was directly associated with operative death in those patients with tracheal surgery and the high incidence of postoperative complication was the most important factors which had rendered the patients moribund after tracheal surgery.      The various operative methods were applied on reconstruction of tracheobronchial                      Table 3.

Especially the complexity of surgical procedures was recognized on the tracheal recons- truction such as direct anastmosis after resection, terminal tracheostomy in the anterior  mediestinum, patch method and sleeve anastomosis. (table 3)        The prognosis after reconstructive surgery does not make surgeon satisfactory. when the replacement with artificial trachea were employed, there were observed the poor pro-gnosis. However its prognosis after tracheal surgery is not only associated with operative method but also is related to preoperative general condition as well as the severity of postoperative complication.                      COMMENT       The reconstructive surgery for the trachea and the bronchus has a further advancing field for wide clinical acceptance. 1)2)3)4)5)       However, following the development of anesthesis and preoperative or postoperative cares, the procedures of the tracheal or bronchial reconstruction for its lesion were applied to relieve and alleviate the suffering from dyspnea. In Japan, the statistical evaluation for tracheobronchial surgery was performed by Hayashi et al.') According to their analysis, the rate of surgical success for the trachea was 57% in constract with 89% for the bronchus. Our studies also resulted in the favorable prognosis of surgery for the bronchus compared with that for the trachea.      The aim of the present study was to certify several factors associated with clinical diff-erences between tracheal and bronchial surgery. It is apparent from these study that its prognosis after tracheal surgery was poor rather than that after bronchial surgery.       In those cases who underwent reconstructive surgery for the trachea in either cervical or thoracic region, its prognosis differ definitely between cervical and thoracic trachea. In majority of those cases with a reconstructive surgery in cervical trachea, the lesion was cha-racterized by cancerous invasion from carcinoma of the thyroid gland and terminal trach-eostomy in the anterior mediastinum adovocated by Grillo7) for repair of stenosis was even-tually utilized as a operative method.      The early and late prognosis after terminal tracheostomy are excellent until at least the recurrence of carcinoma occurs.      By long term follow-up study, no manifestation of threat to life and no ill effects have been noted except interference with phonation.       In general, its prognosis after surgery of tracheal reconstruction are poor except that after surgery of cervical trachea. In constrast with these results, its prognosis after perfor-ming bronchial reconstruction are far superior to that after tracheal reconstruction.      Currently bronchoplastic prcedures of the bronchus is applied as surgical treatment for the patients with hilar type of lung cancer to maintain the preservation of pulmonary function after surgery.      It is defined by some investigators that pulmonary resection with bronchoplasticprocedures are the valuable and commendable operative method from the view of the pro-gnosis and postoperative pulmonary function.       From the present study, causative factors were analyzed clinically with reference to poor prognosis after tracheal surgery. We were concerned about the degree of preoperative respiratory distress which relate directly to operative death.      Aside from clinical sign, the difficulty of surgical technique and the complexity of respiratory care during operation have also related to surgical mortality.      When the extent of tracheal L esion lies in length of more than 6 cm through longitudinal axis, artificial prosthesis is necessary to perform the tracheal reconstruction. However, inconsistant successful rates of experimental tracheal replacement have caused surgeons to be reluctant to use prosthtic trachea. For further advancement of tracheal surgery, it de mands to facilitate an ideal development and the satefy clinlcal application of tracheal pro-sthesis.      Since the occurrence of postoperative complication associates virtually with a trigge of postoperative death, the low incidence of postoperative complication allows to overcome various hinderance in the course of development of tracheal surgery.      However, the major complications such as pulmonary infection appeared to reflect immunological incompetence prior to operation.      The early diagnosis and restricted determination of surgical indication are indispen-sable not only to establish a safety application of tracheal surgery but also to alleviate pro-gressive respiratory distress.
