The 27 countries of the EU, and Andorra, Iceland, Israel, Norway and Switzerland (West, no data from Monaco and San Marino), reported 89,032 TB cases in 2006. TB notification rates (17/100,000 overall) were highest in Romania (128/100,000) among the European countries in 2006. In our county (Timis County), TB notification rates are even higher than the Romanian average, as shown in Table 1.

Indications for surgery comprise: complications resulting from previous surgery, failure of medical therapy (progressive disease, lung destruction, and left bronchus syndrome, lung gangrene, drug resistance, aspergillosis), surgery for diagnosis (pulmonary lesions or mediastinal adenopathy of unknown cause), complications of scarring (massive hemoptysis, cavernoma, lung cancer, tracheoesophageal or bronchoesophageal fistula, bronchiectasis, extrinsic airway obstruction by tuberculous lymph nodes, endobronchial tuberculosis and bronchostenosis, middle lobe syndrome), extrapulmonary thoracic disease (tuberculosis of the heart and great vessels, vascular malformations, pericarditis, cold abscesses and osteomyelitis of the chest wall, Pott's disease), pleural tuberculosis (pleural effusions including pleural thickening, bronchopleural fistula), and infections with Mycobacteria other than Tubercle Bacilli [2].

Ninety-seven men and 47 women entered the study (M:F=2.1:1). The mean age was 44±14.7 (S.D.) years, range 16–79 years.
Most of the patients (107 patients or 74%) had no etiological diagnosis at their admittance; they were referred to us mostly with the diagnoses of pulmonary nodules or tumors or pleural collections of unknown etiology. The remaining 37 patients (26%) with known history of TB have received complete anti-TB chemotherapy cure(s) according to the Romanian National Program of Tuberculosis Control by the time of their admission to our clinic.
The diagnoses at the admittance for which surgery was indicated are shown in Table 2.

Intraopertive samples were taken and sent for histopathological examinations (native or frozen sections), however, these samples did not change the fact that the majority of the patients had not had a confirmed diagnosis until the operation.
After having been discharged, all the patients were referred to a pulmonologist for anti-TB chemotherapy.
We retrospectively reviewed these smear-negative surgical TB cases in the terms of primary surgical procedures, postoperative morbidity and mortality, management of the complications, re-operations, and length of stay. No long-term follow-up was possible. Clinical data are reported as mean±standard deviation (S.D.) with the indication of range. The protocol of the current study was approved by the Ethical Committee of Municipal Clinical Emergency Hospital Timisoara.

Seventy patients underwent VATS procedures. VATS procedures were used in all the cases where the main objective was to establish a correct diagnosis (biopsies of the pleural, pulmonary mediastinal or pericardial lesions), but also with therapeutic goals: wedge resections, decortications, pleuro-pericardial windows.
Pathology examination of the specimens yielded evidence of TB lesions or TB sequelae in all the cases.
Eleven patients had to undergo secondary surgery due to postoperative complications (7.6% of all the patients). Ten of these patients had undergone open thoracotomy procedures (13.5% of the thoracotomy group). One patient had postoperative complications in the VATS group (1.4%). Very high morbidity was met in the pneumonectomy patients. Three patients (50%) out of six presented complications (1 postoperative hemorrhage with residual clot, 2 empyemas with bronchial stump insufficiency and 1 empyema without fistula).
The above-mentioned postoperative complications are detailed in Table 4.

No in-hospital mortality was registered.

Among the 104 open thoracotomy procedures, we prefer to do sublobar resections when cancer is excluded by preoperative or intraoperative histopathological examination in order to save as much parenchyma as possible. Therefore, atypical (wedge) resections were the most numerous in these cases with a fairly low complication rate of 8%. However, for extensive lesions that interested the whole lobe with nearly no functional parenchyma remaining we performed lobectomies; as well as for destroyed lungs pneumonectomies.
Pneumonectomies were done through classic posterolateral thoracotomies. Bronchial closure was done with a stapling device, and the bronchial stump was routinely enforced with mediastinal fat pad and by adjacent tissues in all the cases. A very high rate of postoperative major complications occurred – 3 patients out of 6 presented unfavorable course immediately after pneumonectomy: clotted hemothorax, 2 empyemas with fistula and 1 empyema without fistula.
Most authors relate acceptable mortality rates in pneumonectomies: 2.5% for Pomerantz and associates [4] and Conlan and colleagues [8] to 7.6% for Reed [9]. However, the reported morbidity rates are high varying between 25 and 38% [7–10], the two major complications being postpneumonectomy empyema and brochopleural fistula.
The management of postpneumonectomy complications is still debated, featuring a wide range of procedures in order to close the bronchial stump, to sterilize the residual cavity and to obliterate it [6–10]. The management in our cases was: one case with clotted hemothorax underwent VATS revision; however, he afterwards developed empyema without bronchopleural fistula that was resolved by re-drainage and irrigation with antiseptic solutions. The two other cases that developed empyemas with bronchial stump dehiscence were subject to re-operations, one case was resolved by revision of the bronchial stump and thoracoplasty, and in one case first an open window thoracostomy was performed and afterwards a contralaterally harvested pedicled latissimus dorsi and serratus anterior muscle-skin graft was transferred to affected side (i.e. left) for filling out the residual postpneumonectomy cavity.
Lobectomies presented a complication rate of 12.5% in our series, in a case of upper right lobectomy for aspergilloma.
For complex pulmonary aspergillomas (5) we performed four lobectomies. In one case with poor general status and severe pulmonary dysfunction we chose the one-stage cavernostomy and myoplasty procedure, similarly to the procedures reported by Gebitekin et al. [11]. The outcomes were favorable, with only one patient presenting a residual infected pleural space after right upper lobectomy, that was resolved by an initial re-drainage and afterwards by a partial upper thoracoplasty.
Thoracoplasties were performed in our institution at the beginning of the studied period; recently plombage procedures with muscle flaps are favored for filling out dead thoracic spaces and reinforcing bronhial stumps. These procedures are considered less mutilating and offer a superior esthetical outcome. Latissimus dorsi and serratus anterior muscles were used similarly to other authors' experience [12] either as primary procedures or for managing postoperative complications.
VATS approach for surgical TB is increasingly used either for its diagnostic or therapeutic role [1, 13–15]. Seventy patients in our study underwent VATS procedures. Pleural biopsy was the most frequent procedure, followed by mediastinal biopsies, wedge resections, decortications and pleuro-pericardial window. While the first enumerated procedures had a primary diagnostic purpose, the latter ones had mainly therapeutic aim although no patient from the VATS group had etiological diagnosis before the operation.
Pleural effusions remain undiagnosed in up to 25% of the cases after the usual investigations (biochemistry, cytology, bacteriology, needle biopsy of the pleura). This percentage of pleurisies of unknown etiology can be reduced to 4% by thoracoscopic biopsies. In a study [13] that compared various diagnostic modalities for TB pleural effusions, thoracoscopy was the most accurate tool for establishing the diagnosis with a diagnostic accuracy of 100% on histology and 76% positivity on culture.
In our series 36 pleural biopsies, 10 mediastinal biopsies and 4 pericardic biopsies yielded evidence of the tuberculous etiology of the underlying disease. Ten atypical (wedge) resections were performed for visible pulmonary lesions which were relatively small (nodules under 3 cm) and marginally situated. VATS decortication for multiloculated pleural effusions was done in ten cases. The pathological examination showed tuberculous lesions in the resected specimens. No conversion to classic open thoracotomy was needed in the studied lot. No in-hospital mortality was registered and only one patient out of 70 presented postoperative complications.
We had confirmation of TB in 21% of the pleural effusions of unknown etiology we had operated on; 61% turned out to be of malignant and 18% of inflammatory origin. In indeterminate empyema and pachypleuritis cases the percentage of TB etiology was 54%, 46% having been caused by non-specific infections. Of all the cases of pneumothoraces operated, 10% were secondary pneumothoraces due to TB infection and 90% were spontaneous. Mediastinal adenopathies were found of neoplastic origin in 72%, of inflammatory origin in 17%, and of tuberculous origin in 11% of the cases. For pulmonary nodules the figures were: 27% tuberculous, 69% malignant, and 4% benign lesions. These data are summarized in Table 6.

Dr. Kerti: Yes, the operative complication is pretty high. And, as I said, this is a study about sputum-negative cases because this is an emergency hospital and we are not allowed to manage TB-sputum-positive cases. And I know that the rate of complications, including bronchopleural fistula, in TB-positive cases and MDR cases is even higher.
As for the first question, we did not have massive hemoptysis cases in the studied period that required surgical management.
