From June 1983 to September 1984, the pleural biopsies with Cope needle were performed at department of thoracic and cardiovascular surgery, Pusan Paik Hospital, Inje college, on 78 patients for exudative pleural effusion caused by various conditions. These results were analyzed clinically and summarized as follows: 2. The accuracy of pleural biopsy was 69.2% [54 of 78 patients]. The accuracy represented by ratio for the number of biopsy was 63.5% [54 of 85 biopsies]. 3. Among 61 patients of tuberculosis or malignancy, 37 [60.7%] were confirmed by pleural biopsy. 4. Tuberculosis was diagnosed in 48 patients, in 26[54.2%] out of these by pleural biopsy alone, in 3[6.2%] by pleural biopsy and isolation of AFB, in 2[4.2%] by pleural biopsy and operation, in 4[8.3%] by isolation of AFB, in 2[4.2%] by operation, and in 11[22.9%] clinically. 5. Among 13 patients of malignancy, 4[30.8%] were diagnosed by cytology alone, 4[30.8%] by pleural biopsy and cytology alone, 4[30.8%] by pleural biopsy and cytology, 1[7.7%] by pleural biopsy alone, 1[7.7%] by pleural biopsy and operation, and remained 3 by operation, lymph node biopsy, or bronchoscopy respectively. 6. False positive of clinical diagnosis was 12.5% for tuberculosis and 28.6% for malignancy. In pathological diagnosis there was no false positive. So specificity of pleural biopsy was very high. But false negative of pleural biopsy was 29.2% for tuberculosis and 46.2% for malignancy. 7. 4 cases[5.1%] of minimal pneumothorax were in the early series.

Background: A closed pleural biopsy is commonly performed for diagnosing patients exhibiting pleural effusion if prior thoracentesis is not diagnostic. However, the diagnostic yield of such biopsies is unsatisfactory. Instead, a thoracoscopic pleural biopsy is more useful and less painful. Methods: We compared the diagnostic yield of needle thoracoscopic pleural biopsy performed under local anesthesia with that of closed pleural biopsy. Sixty-seven patients with pleural effusion were randomized into groups A and B. Group A patients were subjected to closed pleural biopsies, and group B patients were subjected to pleural biopsies performed using needle thoracoscopy under local anesthesia. Results: The diagnostic yields and complication rates of the two groups were compared. The diagnostic yield was 55.6% in group A and 93.5% in group B (p<0.05). Procedure-related complications developed in seven group A patients but not in any group B patients. Of the seven complications, five were pneumothorax and two were vasovagal syncope. Conclusion: Needle thoracoscopic pleural biopsy under local anesthesia is a simple and safe procedure that has a high diagnostic yield. This procedure is recommended as a useful diagnostic modality if prior thoracentesis is non-diagnostic.

연구 배경 : 경피적 늑막 침 생검술은 항산균 검사 음성이고 세포진 검사에서 악성세포를 찾을 수 없는 림프구 우위성 삼출성 늑막액의 진단에 있어서 시금석으로 여겨져왔다. 그러나 경피적 늑막 침 생검술은 침습적인 시술이며 그 진단율이 않고 비교적 높은 부작용을 동반한다. 최근 흉수의 adenosine deaminase와 carcinoembryonic antigen의 농도가 결핵성 늑막염과 악성 감별에 도움이 된다고 보고되고 있는데 이런 상황에서 경피적 늑막 칩 생검의 유용성을 재평가하고자 하였다. 연구 방법 : 1994년 1월부터 1996년 2월까지 서울대학교 병원에 입원한 림프구 우위성 흉막 삼출증 환자 중 항산균 도말 검사가 음성이고 세포진 검사 역시 음성이어서 늑막 침 생검을 시행한 73명의 환자를 대상으로 하여 늑막 침 생검의 결과와 합병증의 병발 비율을 조사하였으며 흉수의 ADA가 40IU/L이상인 집단, CEA가 10ng/ml 이상인 집단과 그렇지 않은 집단으로 분류하여 각각의 최종 진단과 늑막 침 생검 결과를 비교분석 하였다. 결 과 : 총 73례의 늑막 침 생검으로 35례에서는 특이 진단이 가능하였는데 모두 결핵성 늑막염과 합치하는 소견이었으며 30례에서는 비특이적 늑막염으로 특이진단을 내릴 수 없었고 나머지 8례는 적절한 늑막 조직을 얻지 못하였다. 기흉등의 합병증은 9례 즉 12%에서 발생하였다. 흉수 ADA 수치가 40IU/L 이상이었던 49례의 경우 진단을 내리지 못한 2례를 제외하고는 모두 결핵성 늑막염으로 진단되어 결핵성 늑막염에 대한 양성예측율은 100%였는데 늑막 침 생검으로는 28례만을 결핵성 늑막염으로 진단할 수 있었다. 한편 흉수 CEA가 10ng/ml 이상이었던 6례는 결국 악성 늑막 삼출 4례, 악정 종양과 연관된 늑막삼출과 결핵성 늑막염 각 1례씩으로 진단되어 악성 늑막 삼출에 대한 양성 예측율은 83%였고 늑막 침 생검으로는 한례도 진단해내지 못하였다. 결 론 : 항산균 도말 검사와 세포진 검사 음성인 림프구 우위성 늑막 삼출의 진단에 있어서 경피적 늑막 침 생검의 진단율은 48%로 높지 않으며 흉수 ADA가 충분히 CEA가 낮은 경우의 결핵성 늑막염에 대한 양성 예측율은 100%로 경피적 늑막 칩 생검의 역할이 재검토되어야 한다.

Malignant mesothelioma is a rare malignant neoplasm that arises from mesothelial surfaces of the pleural cavity, peritoneal cavity, tunica vaginalis, or pericardium. Typically, pleural fluid cytology or closed pleural biopsy, surgical intervention (video thoracoscopic biopsy or open thoracotomy) is conducted to obtain pleural tissue specimens. However, endobronchial lesions are rarely seen and cases diagnosed from bronchoscopic biopsy are also rarely reported. We reported the case of a 77-year-old male who was diagnosed as malignant mesothelioma on bronchoscopic biopsy from obstructing masses of the endobronchial lesion.

Pleural effusion is a rare complication in non-tuberculous mycobacterial infection. We report a case of Mycobacterium intracellulare pleuritis with idiopathic pulmonary fibrosis in a 69-year-old man presenting with dyspnea. Pleural effusion revealed lymphocyte dominant exudate. M. intracellulare was identified using a polymerase chain reaction-restriction fragment length polymorphism method and liquid cultures of pleural effusion and pleural biopsy. After combination therapy for M. intracellulare pulmonary disease, the patient was clinically well at a 1-month follow-up.

Pleural mesothelioma which arise from pleura is relatively uncommon tumor. We are reporting 2 cases of pleural mesothelioma which were treated with surgical resection. First case, benign epithelial mesothelioma was confirmed incidentally after decortication due to localized pleural thickening. The second case, malignant mesothelial mesothelioma was diagnosed by examination of chest radiology, diagnostic pneumogram and pleural biopsy as malignancy which was treated with the resection of the tumor mass. In the first case, postoperative recurrence of tumor growth was found within 1.5 months after resection. In the section malignant case, no evidence of recurrence was noted even after 3 months of resection.

Background: Tuberculous pleurisy is the leading cause of pleural effusion in Korea. And differential diagnosis of tuberculous pleurisy with other cause is clinically very important. Traditional diagnostic methods such as routine analysis of pleural fluid, staining for acid-fast bacilli or pleural biopsy have major inherent limitaion. This study was designed to evaluate the significance of pleural fluid polymerase chain reaction(PCR) and adenosine deaminase (ADA) activity in early diagnosis of tuberculous pleurisy. Material and Method: Between March 1996 and July 1997, 198 patients with pleural effusion reviewed retrospectively. The study group included 112 cases with tuberculous effusion and 86 cases with non-tuberculous effusions, whose diagnoses were confirmed by pleural biopsy, microbiological methods, or cytology. We compared the results of PCR and pleural fluid levels of ADA between tuberculous and non-tuberculous effusions. Result: Mean age was 47.54$\pm$19.52 years(range 2 to 85 years). The positive rate of PCR was significantly higher in tuberculous group than non-tuberculous group(p<0.05). The sensitivty, specificity, positive predictive value(PPV), and negative predictive value(NPV) for PCR were 31.7, 90.9, 83.0, and 48.8%, respectively. Mean ADA activity was significantly higher in tuberculous group than non-tuberculous group(83.2 U/L vs 49.8 U/L)(p<0.05). With diagnostic thresholds of 40 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 75.9, 70.9, 77.3, and 69.3% respectively. At a level of 70 U/L, the sensitivity, specificity, PPV, and NPV of ADA for tuberculosis were 70.1, 75.9, 82.9, and 60.3% respectively. Conclusion: PCR is very highly specific, but less sensitive methods in diagnosis of tuberculous pleurisy. But ADA level of pleural fluid has acceptable sensitivity and specificity in diagnosis of tuberculous pleurisy. ADA activity is more useful test in the evaluation of pleural effusions.
