EXPERIMENTAL AND CLINICAL STUDY ON HEALING PROCESS OF BRONCHOPLASTY WITH AND WITHOUT WRAPPING
―ESPECIALLY EXPERIMENTAL REVASCULALIZATION OF BRONCHIAL ARTERY AT THE ANASTOMOTIC SITES IN THE WOUND HEALING一

The benefit of wrapping procedure for bronchial anastomotic sites was evaluated on the basis of the findings in relation to recanalization of the bronchial artery. It was experimentally tested by wrapping with pedicled-omentum, -pericardium, -pleura and free-pleura in comparison with non-wrapping. Arterial blood supply to the distal bronchial wall at anastomosis was observed at the earliest time following surgery using the omental wrapping. The non-wrapping anastomotic sites showed the same revascularization as the pedicled -pericardial, -pleural wrapping, but by the free-pleural wrapping it was delayed than other 4 groups.
We have performed 77 bronchoplasty for lung cancer. Fifty Seven of them were non-wrapping and the anastomosis dehiscence occurred in 4 cases (6.8％). Other 20 were covered with the pleural (18), pericardium (1), azygos vein (1) and omentum (1) and only one patient using azygos vein had anastomosis dehiscence (4.8％). Omentopexy to the tracheobronchial surgery were performed in 4 cases. These results suggest that wrapping procedure with pedicled-pericardium, -pleura at anastomotic sites which is directly contact with the pulmonary artery and covering of weakened tracheobronchus in surgery with omentum is very useful method for protection and recanalization.
