RESUMO
Chest tubes are routinely inserted after thoracic surgery procedures in different sizes and numbers. The aim of this study is to assess the efficacy of Smart Drain Coaxial drainage compared with two standard chest tubes in patients undergoing thoracotomy for pulmonary lobectomy. Ninety-eight patients (57 males and 41 females, mean age 68.3 ± 7.4 years) with lung cancer undergoing open pulmonary lobectomy were randomized in two groups: 50 received one upper 28-Fr and one lower 32-Fr standard chest tube (ST group) and 48 received one 28-Fr Smart Drain Coaxial tube (SDC group). Hospitalization, quantity of fluid output, air leaks, radiograph findings, pain control and costs were assessed. SDC group showed shorter hospitalization (7.3 vs. 6.1 days, p = 0.02), lower pain in postoperative day-1 (p = 0.02) and a lower use of analgesic drugs (p = 0.04). Pleural effusion drainage was lower in SDC group in the first postoperative day (median 400.0 ± 200.0 mL vs. 450.0 ± 193.8 mL, p = 0.04) and as a mean of first three PODs (median 325.0 ± 137.5 mL vs. 362.5 ± 96.7 mL, p = 0.01). No difference in terms of fluid retention, residual pleural space, subcutaneous emphysema and complications after chest tubes removal was found. In conclusion, Smart Drain Coaxial chest tube seems a feasible option after thoracotomy for pulmonary lobectomy. The SDC group showed a shorter hospitalization and decreased analgesic drugs use and, thus, a reduction of costs.

BACKGROUND: Increased age of cancer patients is not an absolute contraindication to pulmonary resection. Different scores have been developed to determine the risk of morbidity and mortality. We have compared four scores in a series of elderly patients with primary or metastatic lung neoplasms who underwent pulmonary resection. METHODS: Data from 150 patients with an age equal or more than 75 years were reviewed. Mean age was 78.3 (range, 75-86) years. Based on medical history and preoperative tests 4 predicting scores were calculated. Statistical analysis was performed to identify which score correlates better with postoperative morbidity and mortality. RESULTS: Mortality at 30 days was observed in 3 patients (2%). Postoperative morbidity was observed in 38 patients (25.3%). Univariate analysis showed that risk factors significantly predicting the onset of postoperative complications were type of resection (P=0.02), American Society of Anesthesiology (ASA) score (P<0.001) and Glasgow Prognostic Score (GPS) (P=0.02). At multivariate analysis smoking and type of resection were significant prognostic factors for both overall and pulmonary morbidity; the ASA score and GPS showed an impact only on overall morbidity. The Cox regression showed significant results for GPS greater than zero and cancer-related death. Age above 80 years was not a negative prognostic factor. A significant difference in terms of 1-year survival was noted in ASA I-II vs. ASA III-IV (90% vs. 78%; P=0.022) and GPS 0 vs. GPS 1 or 2 (90% vs. 77%; P=0.02). CONCLUSIONS: Prognostic scores are useful to predict postoperative morbidity and mortality and GPS seems to correlate better with them.
RESUMO
BACKGROUND: Tumor with adjacent lobe invasion (T-ALI) is an uncommon condition. Controversy still exists regarding the optimal resection of adjacent lobe invasion, and the prognostic value in relation to fissure integrity at the tumor invasion point. The aims of this paper were to evaluate the prognosis of T-ALI with regard to fissure integrity, and type of resection. METHODS: This was a retrospective multicenter study which included all consecutive patients with T-ALI undergoing surgical treatment. Based on radiological, intraoperative and histological findings, T-ALI patients were differentiated into two groups based on whether the fissure was complete (T-ALI-A group) or incomplete (T-ALI-D Group) at the level of tumor invasion point. Clinico-pathological features and survival of two study groups were analyzed and compared. RESULTS: Study population included 135 patients, of these 98 (72%) were included into T-ALI-A group, and 37 (38%) into T-ALI-D Group. T-ALI-D patients had better overall survival than T-ALI-A patients (63.9 ± 7.0 vs. 48.9 ± 3.9; respectively, P = 0.01) who presented with a higher incidence of lymph node involvement (35% vs. 4%; P = 0.004), and recurrence rate (43% vs. 16%; P = 0.01). At multivariable analysis, T-ALI-D (P = 0.01), pN0 stage (P = 0.0002), and pT≤5 cm (P = 0.0001) were favorable survival prognostic factors. CONCLUSIONS: T-ALI-D presented a better prognosis than T-ALI-A while extent of resection had no effect on survival. Thus, in patients with small T-ALI-D and without lymph node involvement, sublobar resection of adjacent lobe rather than lobectomy could be indicated. KEY POINTS: The extent of resection of adjacent lobe had no effect on survival while T-ALI-D, pN0 stage, and pT≤5 cm were significant prognostic factors. In patients with small T-ALI-D and without lymph node involvement, sublobar resection of adjacent lobe could be indicated as an alternative to lobectomy.

INTRODUCTION: After lung transplantation (LTx), infections caused by multidrug-resistant (MDR) bacteria are frequent and difficult to treat. Some new antibiotics seem to be effective in treating these infections. MATERIAL AND METHODS: We describe our experience in treatment of Klebsiella pneumoniae MDR and Pseudomonas aeruginosa MDR infections with ceftazidime-avibactam (CEF-AVI) and ceftazidime-tazobactam (CEFT-TAZ) in patients who underwent LTx. RESULTS: In 3 patients who underwent double LTx and in 4 patients who underwent single LTx, strains of K. pneumoniae and P. aeruginosa were isolated from bronchoalveolar lavage. All patients showed worsening of respiratory functions, increasing in inflammation indexes, and, in some cases, onset of pulmonary consolidation. P. aeruginosa was treated with CEFT-TAZ for 10 days average (7-15 days) and K. pneumoniae with CEF-AVI for 14 days average (4-24 days). One patient developed a septic state caused by K. pneumoniae, requiring 24 days of therapy. None had shown side effects caused by drugs administration. One patient died after 15 days from lung transplant owing to primary graft dysfunction. CONCLUSIONS: CEF-AVI and CEFT-TAZ seems to be effective in treatment of infections caused by MDR bacteria after lung transplant.

INTRODUCTION: Malignant diseases are well-known complications after lung transplantation (LT). Among these, inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with a not well-known and often aggressive biological behavior. MATERIAL AND METHODS: We hereby describe 2 cases of cystic fibrosis patients who underwent bilateral sequential LT (BSLT) complicated by IMT. RESULTS: A 26-year-old man presented a right endobronchial lesion 6 months after BSLT. Two consecutive fiber bronchoscopic biopsies showed granulation tissue. For the persistent lesion growth, the patient underwent a transthoracic biopsy showing histologic diagnosis of IMT. Therefore, he underwent to right pneumonectomy that was unfortunately complicated after 6 months with a late bronchopleural fistula and empyema with exitus 6 months later. A 31-year-old woman 1 year after BSLT presented with a left voluminous pleural-parenchymal lesion; the histologic examination after biopsy revealed an IMT. She underwent a removal of the lesion with a macroscopic R0 resection. Histologic, immunophenotypic, and cytogenetic examinations showed a strong overexpression of anaplastic lymphoma kinase requiring biological adjuvant therapies; however, the patient refused it. Four years later, she presented a recurrence treated with debulking procedure and adjuvant radiotherapy. At last follow-up, the patient was alive with stable disease and optimal graft function. CONCLUSIONS: Although IMT is a rare complication after lung transplant, to obtain a careful diagnosis, an early and aggressive treatment is mandatory.

BACKGROUND: Vena cava anomalies are a rare group of anatomical variations due to an incorrect development of the superior or inferior vena cava during fetal life. They generally show no clinical relevance and the diagnosis is done due to the association with congenital heart diseases in most of cases. However, preoperative identification of these anomalies is mandatory for surgeons to proper surgical planning. If not recognized, lethal complications may occur, as already reported in literature. CASE PRESENTATION: We report a case series of three different unidentified vena cava anomalies in patients undergoing lung resection. These unrecognized anomalies led to minor complications in two cases and required an accurate intraoperative evaluation in another. A careful retrospective evaluation of preoperative radiological images showed the anomalies. CONCLUSIONS: A careful evaluation of the vena cava anatomy at pre-operative imaging is mandatory for thoracic surgeons to properly plan the surgery and avoid complications.

BACKGROUND: This retrospective study is designed to evaluate factors affecting survival in a population of patients receiving pulmonary metastasectomy after gynecologic cancers. METHODS: Nineteen patients with isolated lung metastases (one or two) were surgically treated with R0 resection. Four of them underwent lobectomies. RESULTS: Six patients (31.6%) received adjuvant therapy and 11 (58%) experienced recurrences after metastasectomy. Five- and ten-year survival were 40.9% and 31.4%, respectively. Five-year survival in patients receiving adjuvant therapy was 52.4%. At multivariate analysis factors negatively influencing survival were a disease-free interval (DFI) of less than 24 months and recurrence after pulmonary metastasectomy. CONCLUSIONS: Pulmonary resection for metastatic gynecologic cancer is feasible and effective; adequate selection of patients is mandatory to achieve satisfactory results and long-term survival.
