[Comparison of typical and atypical bronchoplasty for bronchogenic carcinoma].

One-hundred and twenty-eight patients who underwent bronchoplasty for bronchogenic carcinoma from 1969 to 1990 were retrospectively analyzed. Ninety-six patients had upper sleeve lobectomy or upper lobectomy with wedge bronchoplasty (typical procedure) and 32 underwent bronchoplasty with lobectomy other than upper lobes (atypical bronchoplasty). The two groups were statistically similar in preoperative characteristics including sex, age, cell types and stages. In typical group, right upper sleeve lobectomy was performed in 48 patients, left upper sleeve lobectomy in 27, right upper lobectomy with wedge bronchoplasty in 11, left upper lobectomy with wedge bronchoplasty in 7 and sleeve bronchoplasty alone in 2. In atypical group, right middle and lower lobectomy with sleeve bronchoplasty in 10 patients, left lower sleeve lobectomy in 5, right lower lobectomy with wedge bronchoplasty in 4 and others in 13. Postoperative mortality was 5.2% in the typical group and 9.4% in the atypical group. Postoperative respiratory complications occurred in 16 patients (50%) in the patients with the atypical group and in 33 (34.7%) in those with typical group. Three years and 5 years survival rates in the typical group were 46 and 40% and those in the atypical group, 27 and 18%. However, there was no statistical difference in survival between the two groups. In conclusion, atypical bronchoplasty is useful for preserving the lung parenchyma, but, careful perioperative management and surgical technique of bronchoplasty are mandatory.
