Abstract
BACKGROUND The purpose of our retrospective study is to confirm that bilobectomy is a feasible operation with an oncological value. METHODS From 1981 to 1998, 46 patients underwent bilobectomy for lung cancer. Eight upper and middle lobectomies (UML) and 38 middle and lower lobectomies (MLL) were performed. Intraoperative pneumoperitoneum was done in 11 MLL. We have considered operative mortality, postoperative complications, the persistence of drainage tubes and the length of hospital stay and the data were statistically compared with those relative to right lobectomies. Survival was estimated with the Kaplan-Meier method and the curves were compared with those of the right lobectomies and right pneumonectomies using the log-rank test. RESULTS Overall morbidity was 43.4%. Mortality was 6.5%. Mean chest tube persistence was 7.8 days and mean hospital stay was 14 days. No statistical significance was found about these data comparing the UML and MLL separately and the bilobectomies with the right lobectomies. The pneumoperitoneum done in the MLL enabled a shorter hospital stay, statistically significant, in comparison with MLL without pneumoperitoneum. The overall 5-year survival rate was 38%. Considering the I and the II stages no statistical differences in survival were found considering the right lobectomies and right pneumonectomies. CONCLUSIONS The bilobectomies can have a role in treatment of lung cancer that is equal to the other standard major resections.

Abstract
Hydatid disease is a worldwide encountered zoonosis but at present very rare in Europe, liver and lungs being the most frequently involved sites. Bone involvement is very uncommon and the vertebral spine is the most common site of skeletal involvement (less than 1% overall). We report a case of vertebral hydatid disease with secondary pleuro-pulmonary involvement successfully treated by emergency spinal decompression followed by lung resection en bloc with chest wall and partial vertebrectomy.

Abstract
BACKGROUND The tracheal reconstruction after wide resections remains a critical surgical problem. Our aim was to replace trachea with a tissue easy to vascularize, which allows a simple reconstruction and does not require an immunosuppressive regimen. MATERIALS AND METHODS A segment of cryopreserved aorta was used in order to verify its adequacy as tracheal substitute. In phase 1, the thoracic aorta of 10 rabbits was excised, obtaining 20 segments that were cryopreserved. Ten segments were implanted in the omentum of 10 rabbits that were sacrificed on postoperative days 7, 14 and 21, and the grafts were examined histologically. In phase 2, a segment of cryopreserved aorta arranged with a silicone prosthesis was transplanted in 10 rabbits and wrapped with omentum. The animals were sacrificed on postoperative days 7, 14 and 21. RESULTS In phase 1, the neovascularization of the grafts was present after 7 days, and after 14 days the fibroblasts invaded the lumen of the aorta. In phase 2, 8 rabbits survived and the histologic examination after 7, 14 and 21 days showed neovascularization, the absence of rejection and the proliferation of fibroblasts inside the lumen of the aorta; this growth has been restrained by an endoluminal prosthesis. CONCLUSIONS Our study demonstrated that replacing the trachea with cryopreserved aorta is technically feasible and does not evoke immunologic reactions. It requires, however, a silicone tube inside the allograft to limit the colonization of fibroblasts.

Abstract
INTRODUCTION The CD44 is a membrane glycoprotein that functions as lymph node homing receptor in lymphocyte activation and is involved in homo- and heterotypic cell adhesion. In several tumor cell lines the expression of splice variants (CD44v6 and CD44v7) are correlated with the metastatic potential and confer an advantage in the early steps of the metastatic cascade. In our study we examined 35 cases of non-small-cell lung cancers (NSCLC) in order to detect the presence of CD44v6 and to compare its expression with the histologic type, degree of differentiation, stage of the tumor and survival of the patients. METHODS CD44v6 expression in frozen tissue sections of 35 patients with NSCLC who underwent pneumonectomy or lobectomy was analyzed with the VFF-7 monoclonal antibody that detected the CD44v6 variant. The data on survival were analyzed by the actuarial method and compared by the log rank test. RESULTS The expression of CD44v6 occurred in all the 20 cases of epidermoid carcinomas tested and in 2 out of the 3 cases of undifferentiated large cell carcinoma and was absent in all the 12 adenocarcinomas. No relationship was found between the presence of this marker and the grading or the stage of the pathology. The 3-year survival rate was 73% for CD44v6-positive and 65% for CD44v6-negative cancer and the comparison was not statistically significant. CONCLUSION These results suggest that in lung cancer the expression of CD44v6 is not a useful prognostic factor.

Abstract
A case of spontaneous intercostal pulmonary hernia as a result of vigorous coughing is reported in a 67-year-old man. The great majority of acquired pulmonary hernias are post-traumatic; rare cases are spontaneous, resulting from prolonged and/or repeated increased intrathoracic pressure. This hernia was successfully repaired with a polyglactin absorbable mesh and approximation of the ribs with heavy stitches. When required, surgical repair is the treatment of choice.

Abstract
A number of biological and predictive markers of non-small cell lung cancer (NSCLC) have been sought, but these have so far been mainly evaluated on surgically resected specimens. Given that fine needle aspiration biopsy (FNAB) is being increasingly used in the diagnosis of NSCLC, its application could be extended to the immunocytochemical detection of biological parameters at the time of diagnosis before surgery. In order to assess the reliability of estimating biological markers on fine needle aspirates (FNAs) from NSCLC, the aim of this study was to compare Ki67 growth fraction, p53 and bcl-2 protein expression as revealed by the immuncytochemical assessment of FNAs obtained from surgical samples with the immunohistochemical results obtained from the corresponding histological sections. FNAs were performed on surgical specimens obtained from 29 NSCLC patients. Ki67, p53 and bcl-2 were cytologically and histologically evaluable in respectively 25, 27 and 19 cases. Concordance between FNAs and corresponding paraffin sections was 84% for Ki67, 93% for p53 and 95% for bcl-2. All of the specimens whose biological parameters were studied by immunocytohistochemistry also underwent flow cytometric DNA analysis of FNAs taken from fresh surgical specimens. Of the 29 cases, 22 were aneuploid and seven diploid. The S-phase fraction (SPF) was evaluable in 62% of cases. Comparison of SPF results on FNAs with Ki67 values evaluated on the corresponding histologic and cytologic specimens, revealed a significant correlation only with histology. Good reproducibility was also found in relation to the immunocytochemical results obtained on FNAs from different areas of the same tumour, showing that tumour heterogeneity does not affect the method. The concordance between the immunocytochemical and immunohistochemical results suggests that FNAB may be a reliable procedure for the biological characterization of NSCLC. Given its limited invasiveness, FNAB could be used in vivo for the preoperative assessment of biological parameters in patients with operable or metastatic NSCLC.

Abstract
The anterior approaches proposed for treatment of the apical chest tumors (anterior transcervical, transmanubrial, and hemi-clamshell) have precise advantages and limits. To avoid these limits we have modified the hemi-clamshell with the resection of the first costal cartilage and the costoclavicular ligament. This allows a wider opening of the sternocostal flap, with safe control of the entire subclavian vessels as well as easier access to the T1 to T3 vertebral bodies and the posterior chest wall.

Abstract
BACKGROUND Postoperative air leaks and pleural residual spaces are often encountered during partial lung resections and may adversely affect the immediate outcome prolonging the hospital stay. At present the only treatment consists of maintenance of the chest drainage under suction until resolution of the leaks. METHODS From January 1995 to December 1997 the authors have operated on and subsequently treated 12 patients presenting prolonged air leaks with residual pleural spaces after lobectomies for lung cancer. The patients underwent respectively: left or right lower lobectomies (n=7), left upper lobectomies (n=3), right upper lobectomies (n=2). In this study the air leak was considered prolonged if it continued and delayed the discharge after surgery beyond the postoperative day 8. The pneumoperitoneum was carried out under local anesthesia. The air was insufflated through a needle inserted just above the umbilical scar as for laparoscopic surgery access up to an amount of about 1200 cc-1300 cc. RESULTS We have obtained in all cases and without complications an immediate reduction in the air leaks and a complete resolution of the residual pleural spaces. Chest drainages were removed from 3 to 4 days after the procedure. CONCLUSIONS The good results achieved suggest that this procedure might be considered for selected cases, being a minor procedure, performed under local anesthesia and with minimum discomfort for the patient.

Abstract
Cowden's disease is an inheritable multiple neoplastic syndrome represented by benign and malignant lesions of skin, digestive tract, mucosae, breast and thyroid. The syndrome, first described by Lloyd and Dennis in 1963, includes benign lung lesions, described in the literature only as hamartomas. The unusual condition of our case consists of multiple and bilateral lipomatous lesions of the lung and of adipose colonic polyps, diagnosed respectively by video assisted mini-thoracotomy and by endoscopic biopsies.

Abstract
BACKGROUND Improvements in surgical equipment have rendered video-assisted thoracic surgery (VATS) an effective device for thoracic surgeons and nowadays several intrathoracic diseases can benefit from this approach. This development has expanded potential use and recently the technical feasibility of major lung resections by VATS has been demonstrated. The authors present their experience with a standard muscle-sparing utility thoracotomy (UT) utilized for all VATS procedures, including major lung resections. METHODS From November 1996 to October 1997, 30 patients were operated on. There were 22 males and 8 females (medium age 58 years; range 24-78). There were 13 anatomical lung resections (i.e.: 11 lobectomies, 1 left pneumonectomy, 1 segmental resection), 8 wedge resections, 3 lung biopsies, 2 debridements of pleural empyema, 2 mediastinal nodes biopsies, 1 esophageal resection for leiomyoma, 1 excision of benign mediastinal cyst. RESULTS No mortality or major morbidity were recorded, as well as no rib fractures due to the rib spreader. Two patients suffered from prolonged air-leaks after respectively left upper lobectomy and lung biopsy and required prolonged chest drainage. Concerning anatomic major lung resections the medium hospital stay was 7.9 days and medium chest tube time was 5.6 days. The utility thoracotomy through the auscultatory triangle proved to be a safe approach and confirmed the technical feasibility of various type of surgical procedures with results comparable to standard open thoracotomy. Our data shows that VATS approach did not seriously affect the duration of hospital stay, chest tube time, the overall morbidity or lung function. CONCLUSIONS As the real benefit of this approach remains controversial, the majority of the studies comparing the VATS approach to conventional muscle-sparing thoracotomy neither nor prospective nor randomized, and several parameters are difficult to evaluate in the literature further study are mandatory.

Abstract
New applications of the video-assisted technique for the management of intrathoracic diseases continue to be developed, including major lung resections for cancer. The differences in the techniques proposed from various centers reflect the fact that the procedure is not accurately standardized yet and that prospective randomized trials with long-term follow-up data are needed. The authors report the results of their preliminary experience with a mini-invasive modern approach for video-assisted anatomic lobectomy: an utility muscle-sparing minithoracotomy through the auscultatory triangle. Eight patients successfully undergone this surgical procedure (7 for non-small cell lung cancer in early stage, 1 for benign disease). No mortality, nor complications (including minor morbidity: i.e. rib fractures) were recorded. Medium hospital stay time was 9.25 days (range 7-16) and chest drainage time 6 days (range 4-11). This operation proved to be technically feasible, although an accurate selection of patients and an adequate training in thoracoscopic procedures are mandatory. According to the more recent literature no significant differences are noted in operation's time, postoperative pain, chest drainage time, hospital stay compared to the standard posterolateral thoracotomy incisions. Otherwise the approach described enables to perform a truly "conservative" operation in conformity with the philosophy of the minimal invasive surgery and the patient's comfort and functional recover 2-3 weeks after surgery seems to be improved.

Abstract
Persistent pleural space must be considered a possible complication after lung resection surgical treatment. Although in most cases the evolution is favourable, the authors suggest the use of the "pleural tent" technique, that compared to others thoracoplasty procedures offers some advantages. A short historical review of the thoracoplasty techniques is presented together with a detailed description of the above-mentioned technique.

Abstract
A considerable difficulty in surgical management of apical chest tumors is represented by the potential involvement of the thoracic outlet anatomic structures (i.e.: vertebral body, subclavian vessels, first rib). Among the various techniques proposed, the anterior trans-cervical approach popularized by Dartevelle significantly improved the radical treatment of these tumors. This approach offers a wide access to the thoracic outlet with satisfactory control of subclavian vessels, safe dissection of brachial plexus and upper part of the mediastinum, permitting a radical treatment. However, this approach is associated invariably with aesthetic deformity, severe impairment in shoulder mobility (due to medial half clavicle sacrifice) and respiratory failure in case of chest wall resection. The authors present their experience with an alternative approach, the trans-manubrial osteomuscular sparing approach to anteriorly situated apical chest tumors recently standardized by Grunenwald and Spaggiari. From June 1996 to June 1997 5 patients were operated on through this approach: 3 non-small-cell lung cancer, 1 pseudotumor, 1 desmoid tumor of the first rib. In 2 cases the resection was extended respectively to the vertebral body (D1-2-3 hemivertebrectomy) and to the subclavian vessels. This patient died on 10-postoperative day for massive pulmonary ernbolism, whereas no other complications were recorded. This technique compared to the approach popularized by Dartavelle presents the same oncological radicality, with a better surgical exposure and with the complete sparing of osteomuscular components that allow the maintainance of shoulder girdle movements associated excellent functional and cosmetic results.

Abstract
BACKGROUND Low-potassium (LP) solution with Dextran (Dx) improves lung preservation. Nevertheless, the role of Dx in simple cold storage is not established yet. This study was designed to investigate the relationship between molecular weight and concentration of Dx in LP solutions and its effects on cell viability after prolonged hypothermic preservation. METHODS Human fetal lung fibroblasts (WI-38) were preserved at 10 degrees C for 16 hrs in five solutions containing respectively Dx11, Dx17, Dx39.2, Dx71, Dx178 at 2% and at 5% concentrations and in LP solution without Dx. Cell viability was assessed by means of both the analysis of the total protein content (cytotoxicity index) and the rate of protein synthesis (index of cellular functioning). RESULTS No differences were recorded in total protein content among the solutions tested. By contrast, the index of cellular functioning was significantly higher using LPDx178 at both concentrations. However, LPDx178 exerted a more significant cytotoxic effect than did LP alone. CONCLUSIONS These effects were not mediated by the variation of osmolarity; two factors probably influenced this protection: the low oncotic pressure of the LPDx178 solution and an effect chemically specific due to the increased molecular weight of Dx still unknown. Nevertheless, during 10 degrees C preservation, WI-38 cells were better preserved with LP solution without Dx confirming, thus, that during simple cold storage the presence of an oncotic pressure might be harmful.

Abstract
The reconstruction of the trachea after wide resections remains a critical surgical problem. Our aim has been to replace trachea with a tissue easy to be vascularized, that permits a simple reconstruction, not requiring an immunosuppressive regimen. We have used a segment of cryopreserved aorta. In the first phase the thoracic aorta of 10 rabbits was excised obtaining 20 segments that were cryopreserved. Ten segments were implanted in the omentum of 10 rabbits that were sacrificed on postoperative day 7, 14 and 21. The histologic examination of the grafts showed the presence of neovascularization after 7 days with obliteration of the lumen by fibroblasts after 14 days. In the next phase the cryopreserved aorta replace an excised segment of trachea. The survived animals were sacrificed 7 and 14 days after the operation. The histologic examination showed the neovascularization of the graft and the absence of rejection.
