[The role of video-assisted thoracoscopic surgery in the treatment of pleural empyema]. / Plevral ampiyemlerin tedavisinde videoyardimli torakoskopik cerrahinin rolü

Pleural empyema is a serious problem which affects any age group and still there is no standard approach. Our purpose in this study was to assess the safety, feasibility and efficacy of the video-assisted thoracoscopic surgery (VATS). Between 1997 and 2004 83 patients with empyema were enrolled in this study. Fifty-four patients were male, 29 females and the mean age was 39.4. The mean duration time of symptoms before VATS was 27.3 days. Twenty-two patients were in group-5, 44 in group-6 and 17 in group-7 according to Light's classification of parapneumonic effusions and empyema. Twenty-one patients underwent chest tube before VATS because of their conditions. VATS was converted to thoracotomy in 13 patients. All patients underwent debridement and irrigation during VATS. The cure was achieved in 58 (69.9%) patients with the mean 7.63 days drainage time. Twelve patients were underwent open decortication in the follow-up period. Ten of them were group-7 and 2 in group-6 (p= 0.006). The diagnosis was achieved in 60 (72.3%) patients as nonspecific pleuritis, tuberculosis in 19 and various diagnosis in 4. There was no mortality and minor complications occured in 14 patients. VATS is a safety and efficacy procedure in the treatment of early stage empyema. Use of VATS in early period of multiloculary empyema, prevents patients from unnecessary thoracotomies.

Management of bilateral pneumothoraces after talc pleurodesis and unilateral lung volume reduction surgery.

Lung volume reduction surgery (LVRS) is one of the surgical options in the treatment of advanced emphysema and may also be considered as a 'bridge' operation to lung transplantation in selected patients. Although its long-term effects are still debatable, some patients significantly benefit from this operation. Secondary spontaneous pneumothorax is one of the commonest complications of severe emphysema that necessitates an emergency drainage procedure. However, there is no satisfactory information regarding the management of this complication occurring after LVRS in the literature. This paper reports a case of bilateral pneumothorax three months after a unilateral LVRS that was performed following a contra-lateral talc pleurodesis for recurrent pneumothorax.

The role of integrated positron emission tomography and computed tomography in the assessment of nodal spread in cases with non-small cell lung cancer.

Integrated positron emission tomography and computed tomography (PET/CT) scanning has become the standard for oncologic imaging. We sought to determine the role of PET/CT in mediastinal non-small cell lung cancer staging. One hundred and twenty-seven consecutive patients were enrolled in the study where PET/CT was performed due to pathologically defined non-small cell carcinoma from a single center. They all underwent complete resection with a thoracotomy and systemic lymph node dissection (SLND) between October 2005 and January 2007. Postoperative pathology results of lymph node stations regarding the nodal spread and stage were compared with clinical stage obtained by PET/CT. The sensitivity, specificity, accuracy, negative predictive value (NPV) and positive predictive value (PPV) of PET/CT in N2 cases were determined to be 72.0%, 94.4%, 92.7%, 97.7% and 49.2%, respectively. Maximum standard uptake (SUV(max)) cut-off value for mediastinal N2 involvement in PET/CT was obtained by applying 'receiver operating characteristic' (ROC) analysis that was set to 5.2. Correct stage with PET/CT was established in 76.3% of cases. Staging of non-small cell lung cancer (NSCLC), according to the PET/CT for which we determined 97.79% NPV, we consider that thoracotomy without preoperative mediastinal invasive staging in cases of negative mediastinal involvement in PET/CT can be certainly performed.
