Accelerated treatment of postpneumonectomy empyema - report of 12-year experience.

We report 12-year experience in the accelerated treatment (AT) of postpneumonectomy empyema (PPE). There were 38 patients (7 females, 31 males) in age 19-80 years. 34 patients underwent pneumonectomy due to non-small cell lung cancer (NSCLC), 2 for other malignancies, and 2 for lung abscess. 19 right and 19 left pneumonectomies were performed. PPE was caused by bronchopleural fistula in 16 cases (42.1%) and by pleural infection in 22 patients (57.9%). The interval between first symptoms of PPE and AT ranged 1-47 months. The technique described by Schneiter et al. is based on repeated debridement/lavage of the postpneumonectomy cavity every second day performed a total of three times. 35 patients (92.1%) were free from empyema definitively. 4 of them required additional thoracomyoplasty and another 2 of them thoracostomy due to PPE recurrence. 1 patient (2.6%) during hospitalisation and 2 (5.2%) didn't complete treatment and remained drain carriers. AT alone without additional procedures healed 29 patients (76.3%). Follow up time for the NSCLC group was 8-148 months (median 67). Cancer recurrence or second malignancy rate was 8/36 (22%). Accelerated treatment of PPE is safe and effective. It provides cure for the vast majority of patients without thoracoplasty. Patients with cancer and PPE tend to live longer than similar patients without PPE.

[Disruption of the middle bronchus]. / Oderwanie oskrzela plata srodkowego.

Disruption of the middle lobe broncus as a result of blunt chest trauma is described. Patient underwent emergency reconstructive operation. Follow-up examination revealed normal postoperative chest radiogram but bronchoscopy showed decreased patency of bronchial anastomosis. Perfusion lung scintigraphy showed severely decreased perfusion of the entire right lung. Concomitant fracture of right clavicle resulted in false joint which required surgical intervention 4 weeks after the chest trauma.

Lung cancer in situs inversus totalis (SIT)--literature review.

We present 21 studies of cases of lung cancer in patients with situs inversus totalis (SIT) published worldwide. The first case was described in 1952. Thirteen patients were from Japan, 4 from Eastern Europe, including 2 Polish cases from the authors` center (Department of Thoracic Surgery, Pomeranian Medical University in Szczecin, Poland), 2 from Western Asia, 1 from the U.S. and 1 from Australia. Male patients (20/21) as well as left-sided lung cancer cases (14/21) and squamous cell carcinoma cases (8/21) dominated in the entire group. Thirteen patients underwent surgical treatment. There were 10 left-sided and 3 right-sided surgical interventions with uneventful intra- and postoperative course. Explorative thoracotomy was performed in one case only on the right side. Upper lobectomy was performed in 5 cases, pneumonectomy in 3 cases, lower bilobectomy and middle lobectomy in one case and lower lobectomy in two cases. Surgery was performed through thoracotomy in 10 cases, VATS-assisted approach in two cases and sternotomy in one case. Descriptions of the surgical anatomy confirmed mirror image of the anatomy in all cases and were consistent with the preoperative CT images. Preoperative diagnosis was discussed including the role of 3-D reconstruction of CT for improving perioperative safety in this group of patients. In conclusion, lung cancer/SIT cases despite inversed but regular anatomy can be operated on radically as cases with normal anatomy with preservation of intraoperative security level.

The impact of the sequence of pulmonary vessel ligation during anatomic resection for lung cancer on long-term survival--a prospective randomized trial.

PURPOSE: The aim of this prospective randomized trial was to assess the influence of the sequence of pulmonary vessel ligation, during anatomic resection, on long term survival in patients with NSCLC. MATERIAL/METHODS: This prospective randomized study included 385 patients treated surgically with lobectomy or pneumonectomy and standard lymphadenectomy between 1999 and 2003. Patients were randomly assigned to either primary ligation of the pulmonary artery or arteries (group A - 215 patients) or of the pulmonary vein or veins (group V - 170 patients). Patients were excluded if the sequence of vessel ligation was affected by technical difficulties or anatomic limitations. Univariate and multivariate analyses included: the sequence of vessel ligation, age, gender, tumor histology, stage (TNM), and cause of death (cancer related or non-cancer related). RESULTS: Median follow-up was 63 months. The groups were comparable regarding gender, histology, type of resection, and T, N, and overall stage. Overall, 5-year survival reached 50% in group A and 54% in group V (p = 0.82) and did not differ significantly in cancer related and non-cancer related deaths (p = 0.67 and p = 0.26, respectively). Univariate analysis identified higher T and N factors, advanced stage, pneumonectomy, male sex, and older age as negative prognostic factors. Multivariate analysis demonstrated that age, T3-4 disease, and nodal involvement were associated with inferior survival. CONCLUSIONS: The sequence of pulmonary vessel ligation during anatomic resection for non-small cell lung cancer does not significantly affect long-term survival.

Model of single left rat lung transplantation. Relation between surgical experience and outcomes.

PURPOSE: The model of unilateral orthotropic left rat lung transplantation is well known and established experimental procedure. The author's personal learning curve of mastery process of this microsurgical procedure is presented. MATERIAL AND METHODS: During 18 months the author has performed 197 single left lung transplantations on the Thoracic Surgery Ward in University Hospital, Berne, Switzerland. There were 147 allogeneic and 50 isogeneic transplantations done. The allogeneic transplantations were carried out from Brown-Norway to Fischer F344 rats whereas isogeneic transplantations were done among Fischer F344 rats solely. Grafted lung was obtained from the intravenously anaesthetised, oxygen-ventilated donor. The implantation was carried out through left posterolateral thoracotomy on the gas anaesthetised, respirator ventilated recipient. The anastomoses of the vessels were done using the cuff technique, bronchi were sutured using continuous running over-and-over suture. Recipients were sacrificed on day 5 post-transplant. All recipients were divided into four consecutive groups. Warm ischaemia time and presence of perioperative pure technical complications were observed. RESULTS: We observed time dependent decline of complications number of consecutive recipient groups, respectively 20, 5, 4, 1. The warm ischaemia time in minutes decreased from 35.6 +/- 5.4 in group I through 26.7 +/- 4.4 in group II, 24.8 +/- 2.3 in group III to 22.0 +/- 3.1 in group IV. CONCLUSIONS: Continuous training of the procedure shortens the average warm ischaemia time and reduces the number of complications. This tedious microsurgical procedure is possible to master by the surgeon.

Effects of linear polyethylenimine and polyethylenimine/DNA on lung function after airway instillation to rat lungs.

Lung transplantation is an acceptable treatment option for various end-stage pulmonary diseases, but long-term survival currently lags behind that after transplantation of other solid organs. We hypothesized that gene transfer to grafts before transplantation may be a useful method to deliver antioxidant and/or anti-inflammatory genes to modulate these processes. For this purpose, we assessed the efficiency of gene transfer and effects on lung function of the synthetic polycation, linear polyethylenimine (PEI), after airway instillation to the lungs of Fischer rats. Twenty-four hours after gene delivery, reporter gene activity in DNA/PEI treated rats was approximately 12-fold higher than that in rats treated with naked DNA, but by 72 hours there was no significant difference between groups and activity had decreased by at least 85%. Function of the transfected left lung was assessed by measuring arterial PaO(2) levels and was found to be significantly lower at 24 and 72 hours after gene transfer in the PEI/DNA group compared with the naked DNA group. The deterioration in lung function correlated with histological findings. Rats treated with PEI alone and sacrificed after 72 hours showed an impairment in lung function similar to that seen with PEI/DNA treatment. Our studies highlight the importance of assessing the functional capacity of a graft after gene transfer to determine suitability for subsequent transplantation.
