Abstract:
Objective To evaluate the positive rate, reliability and safety of thoracoscope pleural brushing for diagnosing malignant pleural effusion. Methods Seventy patients with unexplained pleural effusion were performed with medical thoracoscopy:(1) Observe the visceral and parietal pleura then use disposable cell brush to obtain specimens from suspect areas and take cytological examination. (2) Observe the parietal pleura then use biopsy forceps to forceps specimens from suspect areas and take histological examination. (3) Compare the positive rate of diagnosis, coincidence rate of pathological type and complication between two methods individual and combination in diagnosis. Results In 51 patients diagnosed as malignant pleural effusion, the diagnosis-positive rate of biopsy was 88.24%(45/51) and the diagnosis-positive rate of pleural brushing cytology was 90.20%(46/51). The diagnosis-positive rate of pleural brushing combined with biopsy was 96.08%(49/51), but there was no significant difference in diagnosis-positive rate between two methods individual and combination for malignant pleural effusion (P>0.05). In 51 patients, pathological type determination rate was 76.47%(39/51) evaluated by pleural brushing, 88.24% (45/51) by biopsy, and there was no significant difference in pathological type determination rate between two methods (P>0.05). Biopsy was performed for 168 times, more bleeding was found in 5 cases (2.98%), feeling pain in 134 cases (79.76%). Pleural brushing examination was performed for 198 times, no significant bleeding and pain were found. Conclusion Medical thoracoscopic pleural brushing under direct vision is a safe and reliable method, which can be use as an effective diagnostic method for malignant pleural effusion.
