title: Postoperative complications after bronchoplastic procedures in the treatment of bronchial malignancies.
abstract: OBJECTIVE
  The purpose of this study was to determine the frequency of postoperative complications after bronchoplastic procedures in the treatment of pulmonary malignant tumors and to analyze the factors influencing the complication rate.
  
  
  METHODS
  During a 5-year-period (1992-1996) 79 patients (68 male, 11 female, mean age 57 years) underwent reconstructive operations for bronchial malignancies. We performed 58 bronchoplastic procedures and 21 combined broncho- and angioplastic procedures. Among the bronchoplastic procedures the number of sleeve resections (n = 44) and wedge resections (n = 35) were comparable.
  
  
  RESULTS
  Fifty-nine patients (74,7%) showed a regular postoperative course; 12 patients (15,2%) had severe postoperative complications (death, re-operation). Concerning the primary operation the operative 30-day mortality was 5.1% (n = 4) and including the two deaths after re-operation it was 7.6% (n = 6). After subdividing the patients into three groups (severe, less severe and no complications) we tried to determine predictors for occurrence of postoperative complications. There was a higher rate of severe complications in the age group 61-70 years (6/25 = 24%) as compared with younger patients between 51 and 60 years (4/38 = 10,5%; P < 0,05). Concerning the location, the outcome was better after sleeve- or wedge lobectomies of the upper lobes (four complications/51 patients = 7.8%) compared with procedures of the lower lobes (3/14 = 21.4%). The data could not prove a lower frequency of severe postoperative complications or specific morbidity after pleural coverage following bronchial sleeve resection. The complication rate was higher when sleeve resection of the bronchus was performed (10/44 = 22.7%) as compared with wedge resections (2/35 = 5.7%; P = 0,011) and after resection of T3/T4 tumors (6/28 = 21,4%) compared with T1/T2 tumors (4/37 = 10.8%; P < 0,05).
  
  
  CONCLUSIONS
  Bronchoplastic procedures represent a fairly safe therapy opportunity in patients with centrally localized bronchial carcinoma and compromised or uncompromised pulmonary function. In this study the complication rate was higher after sleeve resection of the bronchus as compared with wedge resection. Pleural coverage of the anastomosis was not effective to prevent major complications due to dehiscence of the bronchial anastomosis. A pedicled muscle flap could be a valuable alternative.
