Abstract

PURPOSE:  To determine the correlation between the changes of bronchoscopic narrowing of the endobroncial lesions and radiographical changes and lung functions following therapy by fiberoptic application of electrocautery.

METHODS:  Consecutive 22 patients with endobronchial lesions. Electrocautery was applied and data were measured before and after one week of treatment. The radiographic signs were collected before and after electrocautery from plain x-ray and computed tomograpgy including the presence of masses, atelectases, metasis, and pleural effusion. Any reduction in the size of the tumour or atelectasis were considered radiographic improvement. The circumference area of the patent area of the bronchus affected measured using the recorded video tape before and after one week of electrocautery. Correlation between the improvement of bronchoscopic view and radiographic data were measured. Also, pulmonary functions were compared before and after one week of electrocautery.

RESULTS:  Twenty two consecutive patients with endobrnochial lesions were included in the study. Age 54±12.39 and males were 77.3% of patients. Malignant lesions were found in 90.9% of patients; of those patients 40.9% had squamous cell carcinoma, 13.6% had small cell carcinoma. The majority (54.5%) had radiological evidence of lung masses, followed by atelectasis in 31.8% of patients. There was evidence of bronchoscopic improvement in 86.4% of patients and radiographic improvement in 54.5% of patients. There was a positive correlation between bronchoscopic and radiographic improvement (p = 0.001). Also, we found a significant improvement in lung functions and oxgen tension after electrocautery.Oxygen tension before and after (65.2±11.3 & 79.1±10.4)(P<0.001). FEV1/FVC was 76.4±10.5 and 83.6±8.1 respectively(p= 0.001) FEF25-75 was 1.7±0.7 and 2.5±1.2 respectively (p=0.004). Six minute walking was 214.1±50.2 and 277.9±48.1 respectively (p<0.001). There was an increase in the patent affected bronchus narrowed by the lesions (1.1±0.2 cm)and (1.9±1.3cm)respectively (P<0.001).

CONCLUSION:  Endobronchial lesions treated by electrocautery are associated with improvement in lung fuctions, radiographic features and bronchoscopic narrowing caused by the lesions.

CLINICAL IMPLICATIONS:  Electrocautery is a cheap effective method to treat endobroncial lesions.
