Intrapleural intercostal nerve block associated with mini-thoracotomy improves pain control after major lung resection.

OBJECTIVE: To prospectively assess the impact of intrapleural intercostal nerve block (IINB) associated with mini-thoracotomy on postoperative pain and surgical outcome after major lung resections. METHODS: Between January 2004 and February 2005, we randomly assigned 120 consecutive patients undergoing mini-thoracotomy (10-13 cm) for major lung resections, to receive or not IINB from the 4th to the 8th space at the moment of thoracotomy using 20 ml (7.5 mg/ml) ropivacain injection at the dose of 4 ml for each space. Postoperative analgesia consisted of continuous intravenous infusion of tramadol (10 mg/h) and ketoralac tromethamine (3 mg/h) for 48 h for all patients. RESULTS: The two groups (60 patients each) were comparable for age, sex, pulmonary function, type and duration of the procedure. Mortality and morbidity were 0% and 10%, respectively, for the IINB group and 3.3% and 15%, respectively, for the non-IINB group (p>0.05, NS). Mean postoperative pain measured by the 'Visual Analogue Scale' were as follows: 2.3+/-1 at 1 h, 2.2+/-0.8 at 12 h, 1.8+/-0.7 at 24 h, and 1.6+/-0.6 at 48 h for the IINB group; and 3.6+/-1.4 at 1 h, 3.4+/-2 at 12 h, 2.9+/-1.2 at 24 h, and 2.0+/-1 at 48 h for the non-IINB group. Differences were significant at 1 h, 12 h, 24 h, and 48 h (p<0.05). Mean postoperative hospital stay was 5.7 days in the IINB group and 6.5 days in the non-IINB group (p<0.05). CONCLUSION: IINB associated with mini-thoracotomy reduces postoperative pain and contributes to improve postoperative outcome after major pulmonary resections.

Reconstruction of the pulmonary artery.

Sleeve resection and prosthetic reconstruction of the pulmonary artery have progressively gained acceptance as an alternative to pneumonectomy in lung cancer surgery. Previous concern was mainly related to technical difficulties, intraoperative and postoperative complications, lack of long-term survival, and impact on cardiopulmonary function. For this reason it was not until very recently that lobectomy associated with resection and reconstruction of the pulmonary artery, associated or not to a sleeve resection of the bronchus, has been demonstrated to be an advantageous alternative. The concern about an increased complication rate has been proven to be excessive; in fact, pulmonary artery reconstruction can be performed safely and effectively with the correct indications and technique. We hereby report our experience, along with a review of the indications, the surgical technique, and outcome of pulmonary artery reconstruction.

Operative endoscopy of the airway with the old-fashioned esophageal dilators.

Bronchial dilation is usually required to treat a number of disorders; the most frequent are complications after airway surgery, including lung transplantation, stenosis after radiotherapy, and compression by an extraluminal mass. The procedure is performed by forcing the tip of a rigid bronchoscope through the stenosis using barrels of increasing size; however, when there is a clear discrepancy between the caliber of the rigid instrument and the stenosis, the first step may be difficult. In such cases, we have successfully employed two types of old-fashioned esophageal dilators rescued from the armamentarium of our endoscopy unit.

Bronchoscopic lung-volume reduction with one-way valves in patients with heterogenous emphysema.

BACKGROUND: We evaluated the feasibility and short-term functional outcome after bronchoscopic lung-volume reduction performed with one-way valves in patients with severe heterogeneous emphysema. METHODS: Thirteen patients entered this pilot study. Endobronchial one-way valves were placed in the segmental bronchi supplying the most hyperinflated parts of the emphysematous lungs to allow lung deflation, reduce lung volume, and alleviate symptoms. The valves and delivery catheter were inserted under intravenous anesthesia and spontaneous assisted ventilation, with visual control through a flexible bronchoscope. We performed unilateral bronchoscopic lung-volume reduction in 11 patients and staged bilateral procedures in 2. Preoperative median forced expiratory volume in 1 second (FEV1) was 0.75 L/s (22%), residual volume was 5.3 L (233%), total lung capacity, 7.9 L (123%); intrathoracic gas volume, 6.5 L (176%); and 6-minute walk test, 223 meters. All patients required supplemental oxygen at rest (1.4 L/min). The median preoperative Medical Research Council (MRC) scale dyspnea score was 4. RESULTS: Six complications occurred in 3 patients: two bilateral and one contralateral pneumothorax, one pneumonia, and two episodes of bronchospasm. Functional results at 1 and 3 months showed a significant improvement in FEV1, residual volume, and 6-minute walk test; 43% of the patients were able to completely stop supplemental oxygen. The posttreatment MRC median dyspnea score at 1 and 3 months was 2. Bronchoscopic follow up at 1 and 3 months showed that the valves were correctly in place with no granulation. CONCLUSIONS: Bronchoscopic lung-volume reduction with one-way valves can be performed with acceptable short-term safety and worthwhile functional benefits.

Treatment of recurrent thymic tumors.

Surgery is the cornerstone of therapy for recurrent thymic tumors. The pattern of recurrence is, however, less defined. Between 1966 and 1988, we operated on 83 patients with thymoma, 11 of whom underwent surgery for recurrence (group I). In 1989, we initiated a prospective multimodality protocol and have enrolled 128 patients with 9 (7%) recurrences since (group II). In group I, 1 patient was originally at stage I, 2 were at stage II, 5 at stage III, and 3 at stage IV. The patients underwent 1 (#10) or 2 (#1) reoperations and 5 showed histological progression of malignancy. One patient died postoperatively, 6 died of disease, and 3 are alive and disease free 18 to 22 years after the first operation. In group 2, no patient was originally at stage I, 1 was at stage II, 4 were at stage III, and 4 at stage IV. Reoperation (5 patients) was followed by chemotherapy and 2 showed histological progression of disease. One patient died after 2 years, and 4 patients are alive after 6 to 11 years. All recurrent tumors were thymomas with cortical differentiation. Early onset of recurrence was a negative prognostic factor. Thymomas can recur also at early stages. A multimodality approach is indicated also for early stage lesions based on histology.

Operative and non-operative treatment of benign subglottic laryngotracheal stenosis.

OBJECTIVE: Surgery is the first line of treatment for laryngotracheal stenosis; Montgomery tube or permanent tracheostomy have been so far the only alternatives. Nd-YAG laser resection and indwelling endotracheal stents have rarely been used in subglottic stenosis for anatomic and technical reasons. We have used the latter approach to optimize the timing of surgery or to achieve palliation without tracheostomy. METHODS: Between 1991 and 2001 we have treated 18 patients with subglottic stenosis (10 males, 8 females; age range 14-78, mean 34). The upper margin of the stricture was 2mm to 1cm below the vocal cords; the stenotic segment extended from 1.5 to 5 cm. Three patients had tracheostomy done elsewhere. Four patients (Group I) had laser and stenting by a Dumon prosthesis as the only treatment; six had laser and stenting (#4) followed after 1-6 months by laryngotracheal resection (Group II); eight had surgery alone (Group III). RESULTS: In Group I, one patient required repositioning of the stent and in two the stent was removed; two patients died of their underlying disease; at a follow-up of 2-9 years all living patients did well but required permanent aerosolized therapy and periodical bronchoscopy. In Group II, we had two wound infections due to airway colonization by staphylococcus aureus. In Group III, two patients developed anastomotic postoperative stenosis, treated by laser (#2) and stenting (#1), and one patient with previous tracheostomy had a wound infection. Overall, in the 14 surgical patients (Groups II and III) stenosis occurred in 14.2% and infection in 21.3%. After a follow up of 15 months to 12 years, all surgical patients breathe and speak well. CONCLUSIONS: Laser resection and endoluminal stenting can be a viable alternative to surgery or optimize the timing of operation in patients with subglottic stenosis.

Bilateral sequential lung transplantation without sternal division.

OBJECTIVES: The 'clamshell incision' is considered the standard approach for bilateral sequential lung transplantation (BSLT); however, a considerable morbidity may be related to this incision. The bilateral anterolateral thoracotomy without sternal division is an alternative approach that may contribute to avoid chest wall complications. METHODS: We have employed this approach in a prospective series of 34 patients undergoing bilateral transplantation (Group I). The results were retrospectively compared with an historical control group of 37 patients (Group II) undergoing transplantation through the clamshell incision. RESULTS: The operative time in Groups I and II were 228+/-32 and 293+/-37 min, respectively; the difference between the ischemic time of the first and second lungs were 68+/-20 and 73+/-15 min. Intensive care unit stay was 5+/-6 vs. 13+/-10 days and length of hospitalization was 25+/-16 vs. 32+/-10 days. Vital capacity measured 3 weeks after the transplant was significantly higher in Group I (65+/-13 vs. 45+/-8% predicted) as well as FEV(1) (71+/-8 vs. 58+/-7% predicted). No wound related complication was observed in Group I; in Group II, there were 17 chest wall complications: sternal osteomyelitis in three patients (surgical debridement and closure with a muscle flap), migration of the Kirshner wire in three (removal of the wire), sternal override in three (surgical correction) and prolonged pain in eight. CONCLUSIONS: The bilateral anterolateral thoracotomy without sternal splitting is a safe and effective approach for BSLT; it allows to avoid sternal complications and contributes to improve respiratory function in the early postoperative period.

Long-term outcome of bilateral lung volume reduction in 250 consecutive patients with emphysema.

OBJECTIVE: Numerous reports have confirmed the early benefits of lung volume reduction surgery for selected patients with emphysema. This report documents the long-term survival and functional results after lung volume reduction surgery. METHODS: Between January 1993 and June 2000, a total of 250 consecutive patients underwent bilateral lung volume reduction surgery through median sternotomy at our institution. All patients had disabling dyspnea, thoracic hyperinflation, and a heterogeneous pattern of emphysema with suitable target areas for resection. Preoperative pulmonary rehabilitation was required and post-rehabilitation data were used as the baseline for data analysis. Follow-up ranged from 1.8 to 9.1 years (median 4.4 years). RESULTS: Prolonged air leaks (>7 days) were the most common complication (45.2%, n = 113). Reexploration rates for air leak and bleeding were 3.2% (n = 8) and 1.2% (n = 3), respectively. Eighteen patients (7.2%) required reintubation and mechanical ventilation. The in-hospital mortality in this series was 4.8% (n = 12). The median length of hospitalization was 9 days (range 4-168 days). Kaplan-Meier survivals after lung volume reduction surgery were 93.6%, 84.4%, and 67.7% at 1, 3, and 5 years, respectively. Eighteen patients (7.2%) have subsequently undergone lung transplantation after a median interval of 4.3 years (range 2.1-6.4 years). Spirometric values, lung volumes, and gas exchange parameters improved after surgery. The forced expiratory volume in 1 second and the residual volume showed statistically significant improvements between preoperative values and each time point of follow-up. Health-related quality of life showed significant postoperative improvement and with time correlated well with the improvement in forced expiratory volume in 1 second. CONCLUSIONS: Lung volume reduction surgery produces significant functional improvement for selected patients with emphysema. For most of these patients, benefits appear to last at least 5 years.

Biopsy of anterior mediastinal masses under local anesthesia.

Treatment of most primary mediastinal tumors is based on positive histological diagnosis; we describe a variation of anterior mediastinoscopy under local anesthesia. After infiltration with local anesthetic, a transverse skin incision is made in the second, third, or fourth interspace. The endothoracic fascia is incised vertically adjacent to the periosteum and a mediastinoscope is inserted in the mediastinum. Between 1995 and 2001, we have employed this technique in 46 patients with anterior mediastinal tumors. Histological diagnosis was obtained in all patients. Pneumothorax (2 patients) was drained by a tube removed at the end of the procedures. No other complications occurred and all patients were discharged from hospital within 24 hours. Mediastinoscopy under local anesthesia proved safe and effective for diagnosing anterior mediastinal tumors.

Does donor cause of death affect the outcome of lung transplantation?

BACKGROUND: Accumulating evidence suggests that the donor's cause of death may influence posttransplantation allograft function. We conducted a retrospective analysis of our adult lung transplant experience to investigate the influence of donor traumatic brain injury versus nontraumatic brain injury on posttransplantation outcome. METHODS: We retrospectively reviewed donor records and recipient medical charts for 500 consecutive lung transplants performed between July 1988 and December 1999. Recipient follow-up was complete, with a minimum follow-up of 1 year of survival. RESULTS: There were 295 and 205 donors in the traumatic and nontraumatic brain injury groups, respectively. Young male donors predominated in the traumatic brain injury group. Recipients receiving donor lungs from the traumatic and nontraumatic brain injury groups did not differ by age, sex, diagnosis, type of transplant (single-lung versus double-lung) or requirement for pretransplantation mechanical ventilatory assistance. Recipients did not differ in immediate or 24-hour PaO (2)/inspired oxygen ratio, ventilation time, hospital stay, hospital mortality, or overall survival. Recipients of organs from donors who died of traumatic brain injury showed a higher severity and frequency of rejection episodes during the first year after transplantation. Freedoms from bronchiolitis obliterans syndrome at 5 years were 34.5% and 50.8% for recipients of organs from donors who died of traumatic and nontraumatic brain injury, respectively (P =.002). CONCLUSIONS: The cause of donor brain death does not appear to influence early results of lung transplantation. Traumatic brain injury, or some phenomenon associated with it, may predispose a transplanted lung and its recipient toward more severe early rejection episodes and subsequent development of bronchiolitis obliterans syndrome.
