OBJECTIVETo explore the role of rigid bronchoscope in the diagnosis and treatment of plastic bronchitis.

METHODSVarious clinical parameters, the key points of operation and postoperative recovery were analyzed in 8 patients with plastic bronchitis treated in Department and ICU using retrospective analysis.

RESULTSAll cases demonstrated bronchial lumen stenosis, mucous membrance coarse, congestion, edema in the affected side. 2 cases had follicular hyperplasia, 1 case had a few ooze after taking out the plastic type. All cases had endogenous foreign bodies, taking the shape of the bronchial tree or a funicular. Block shape and sites were as follows: right main bronchus 2 cases, superior lobe of right lung 1 case, right middle bronchial 1 case, left main bronchus 2 cases, 1 case with left lower lobe, right main bronchus and left lower lobe bronchus 1 case. The breath sounds of the affected side become more enhanced after operation, with the alliviation of dyspnea. All cases recovered after ICU treatment. The pathologic examination were all type I plastic bronchitis.

CONCLUSIONSRemovement of the endogenous foreign body via rigid bronchoscopy is the effective method in the treatment of plastic bronchitis. Plastic bronchitis is a rapid-developing critical, urgent disease.In order to reduce the mortality, early diagnosis and timely surgery are necessary.
