Surgery for non-localized bronchiectasis.

BACKGROUND: Resection for localized bronchiectasis is a well established therapy. However, there is little information on the role of surgery in non-localized bronchiectasis. METHODS: Between January 1992 and April 2001, 55 patients without cystic fibrosis underwent resection. Forty-eight patients (mean age 45 (range 23-74) years; 32 women) were available for long-term follow-up. Twenty-five patients underwent resection for localized disease (group 1) and 23 had bronchiectasis in at least two different lobes (group 2). RESULTS: Thirty-one of the 48 patients were treated by Video Assisted Thoracoscopic Surgery (VATS) resection. There was no 30-day mortality. Mean duration of hospital stay was 10.9 (range 6-31) days in group 1 and 11.1 (range 5-19) days in group 2. Three of 25 patients in group 1 required reoperation. Only minor complications occurred in group 2 (three patients). Mean follow-up for both groups was 37 (range 6-97) months. Twenty-three of 25 patients in group 1 and 16 of 23 in group 2 reported satisfaction at 6 months after the operation. Recurrent infection was noted in three patients in each group. Haemoptysis recurred in only one patient in group 2. CONCLUSION: The surgical treatment of selected patients with non-localized bronchiectasis was safe and most patients were satisfied with the outcome.

Non-steroidal anti-inflammatory drugs decrease the quality of pleurodesis after mechanical pleural abrasion.

OBJECTIVE: Non-steroidal anti-inflammatory drugs (NSAIDs) are often applied for pain management after thoracic surgery. Since these drugs diminish collagen deposition through inhibition of the prostaglandin synthesis, we investigated their effects on adhesion formation after endoscopic mechanical pleural abrasion, which is often applied in the therapy of pneumothorax. METHODS: Mechanical pleural abrasion was performed unilaterally by the use of video-assisted thoracoscopic surgery technique in an established pig model. Ten animals (41.3+/-3.4 kg) were divided into a treatment group and a control group. In the treatment group, animals received 100 mg diclofenac (2 mg/kg body weight) orally daily for 3 weeks after surgery. At 3 weeks, all animals were sacrificed and efficacy of pleurodesis was macroscopically assessed by three independent reviewers blinded to the treatment of animals using a five-point severity pleurodesis score (from 0, no adhesions to 4, complete symphisis) and obliteration grade rating the distribution of adhesions (from 0, no adhesions to 4, adhesions in the whole chest). Microscopic evaluation was performed by two pathologists blinded to the study groups as well. A four-point score assessed the amount of collagen deposition (from 1, a few collagen fibers to 4, scar). RESULTS: Gross observation showed more dense adhesions in control animals with a median pleurodesis score of 3.67+/-1.0 in comparison to 2+/-2.2 in the treatment group (P = 0.01 *, Mann-Whitney non-parametric test). Distribution of adhesions was comparable in both groups with a median obliteration score of 3.67+/-1.3. Histopathologic examination showed a higher amount of collagen deposition in the control group, suggesting more dense adhesions, whereas in the treatment group there was loose granulation tissue (score of 4.0+/-0.8 vs. 2.3+/-1.0 in the treatment group, P = 0.06). The degree of inflammatory reaction was comparable in the two groups. CONCLUSIONS: Our results demonstrate that perioperative use of NSAIDs highly affects the quality of pleural adhesions obtained after mechanical abrasion in this pig model, which further suggests that these drugs should be avoided for pain management when a pleurodesis is performed.

Bronchoscopic radioisotope injection for sentinel lymph-node mapping in potentially resectable non-small-cell lung cancer.

OBJECTIVE: Prospective study to evaluate the feasibility of a preoperative bronchoscopic radioisotope application, followed by conventional sentinel lymph-node (SLN) identification and to investigate the occurrence and distribution of micrometastases in relation to SLN activity. METHODS: Twenty patients with a mean age of 63 years and proven clinical stage T1-3 N0-1 non-small-cell lung cancer (NSCLC) were included. A dosage of 80MBq radiolabeled technetium-99m nanocolloid was endoscopically administrated on intubated patients in the operation theatre. At thoracotomy, scintigraphic readings of both the primary tumor and hilar and mediastinal lymph-node stations were obtained with a hand-held gamma-counter. Patients underwent lung resection and mediastinal lymphadenectomy. Radiolabeled nodes were also examined separately on back-table. SLNs were defined as the hottest nodes or nodes with at least one-tenth of the radioactivity of the hottest nodes. SLNs pathologic assessment included standard examination using hematoxylin and eosin staining on step sections and immunohistochemistry (ICH) for cytokeratins. RESULTS: Identification of SLNs was possible in 19/20 (95%) patients after bronchoscopic radioisotope application. In 7/19 (37%) patients, a unique SLN was identified, whereas in 12/19 (63%) patients, nodes from two different stations could be classified as SLNs. Metastatic nodal disease was found in 9/19 (47%) patients. ICH revealed micrometastases in 2/12 (17%) patients, initially classified nodal negative. Pathologic negative SLNs were a predictor for absence of metastatic nodal disease after mediastinal lymphadenectomy. No complication related to the procedure was observed. CONCLUSION: Our preliminary results suggest that preoperative bronchoscopic radioisotope injection for SLN identification is a safe and simple method, improving accuracy of SLN detection in comparison to intraoperative technique. The absence of metastases in the SLNs seems to predict a negative nodal status accurately.

Morbidity and outcome after sentinel lymph node dissection in patients with early-stage malignant cutaneous melanoma.

OBJECTIVE: Prospective analysis of the morbidity and outcome of the sentinel lymph node (SLN) technique in a consecutive series of patients with early-stage melanoma. METHODS: Between 1997 and 1998, 60 patients with stage IB-II malignant melanoma underwent SLN dissection. Preoperative dynamic lymphoscintigraphy with mapping of the lymph vessels and lymph nodes and location of the sentinel node was performed the day before SLN dissection. SLN was identified by use of the blue dye technique. SLN was assessed for histopathological and immunohistochemical examination. Postoperative morbidity and mortality were recorded. Follow-up consisted of repetitive clinical examination with lymph nodes status, laboratory and radiologic findings. RESULTS: Tumor-positive SLN was observed in 18% of the patients and stage II disease was found in 91% of the patients with positive SLN. Breslow thickness was the only significant factor predicting involvement of a SLN (p = 0.02). In 36% of the positive SLN, metastases could be assessed only by immunohistochemical examination. Postoperative complications after SLN dissection were observed in 5% in comparison with 36% after elective lymph node dissection. After a mean follow-up of 32 months, recurrence was observed in 3% with a mean disease-free survival of 8 months. Overall survival was 82% and 90% in patients with positive and negative SLN, respectively. Overall mortality was 15%, due to distant metastases in 78% of the cases. CONCLUSIONS: Staging of early-stage melanoma with the SLN dissection by use of the blue dye technique combined to lymphoscintigraphy and immunohistochemistry is reliable and safe, with less morbidity than elective lymphadenectomy. Long-term follow-up is mandatory to establish the exact reliability of SLN dissection.

Embolization of a ruptured intercostal artery aneurysm in type I neurofibromatosis.

We present the case of a female with history of a ruptured lumbar aneurysm years ago. She was known to have neurofibromatosis type I with the typical clinical signs. The patient was transferred to us with a hematothorax and an aortic lesion was suspected on the outside CT scan. Reevaluation of the investigation raised suspicion of a ruptured intercostal artery aneurysm, which was consequently demonstrated on angiography. The aneurysm was embolized and the patient recovered uneventful. We will discuss the optimal therapy for vessel lesions in neurofibromatosis type I.

Pulmonary function testing after operative stabilisation of the chest wall for flail chest.

OBJECTIVE: This is a prospective evaluation of chest wall integrity and pulmonary function in patients with operative stabilisation for flail chest injuries. METHODS: From 1990 to 1999, 66 patients (56 men, 10 women; mean age 52.6 years) with antero-lateral flail chest (> or =4 ribs fractured at > or =2 sites) underwent surgical stabilisation using reconstruction plates. Clinical assessment and pulmonary function testing were performed at 6 months following surgery. RESULTS: Fifty-five (83%) patients had various combinations of injuries of the thorax, head, abdomen and extremities. Sixty-three (95.5%) patients underwent unilateral and 3 (4.5%) patients bilateral stabilisation with a median delay of 2.8 days (range 0-21 days) from admission. The 30-day mortality was 11% (seven of 66 patients). Immediate postoperative extubation was feasible in 31 of 66 patients (47%) and extubation within 7 days following stabilisation in 56 of 66 patients (85%). No plate dislocation was observed during the follow-up. The shoulder girdle function was intact in 51 of 57 patients (90%). Chest wall complaints were noted in 6 of 57 (11%) patients, requiring removal of implants in three cases. All patients returned to work within a mean period of 8 (range 3-16) weeks following discharge. Pulmonary function testing (n=50) at 6 months after the operation revealed a significant difference of predicted vs. recorded vital capacity (VC) and forced expiratory volume in 1s (FEV1) (P=0.04 and P=0.0001, respectively; Wilcoxon signed-rank test). The median ratio of the recorded and predicted total lung capacity (TLC) was shown to be significantly higher than 0.85 (P=0.0002; Wilcoxon signed-rank test), indicating prevention of pulmonary restriction. CONCLUSION: Antero-lateral flail chest injuries accompanied by respiratory insufficiency can be effectively stabilised using reconstruction plates. Early restoration of the chest wall integrity and respiratory pump function may be cost effective through the prevention of prolonged mechanical ventilation and restriction-related working incapacity.

Prognostic relevance of Masaoka and Müller-Hermelink classification in patients with thymic tumors.

BACKGROUND: To compare the prognostic relevance of Masaoka and Müller-Hermelink classifications. METHODS: We treated 71 patients with thymic tumors at our institution between 1980 and 1997. Complete follow-up was achieved in 69 patients (97%) with a mean follow up-time of 8.3 years (range, 9 months to 17 years). RESULTS: Masaoka stage I was found in 31 patients (44.9%), stage II in 17 (24.6%), stage III in 19 (27.6%), and stage IV in 2 (2.9%). The 10-year overall survival rate was 83.5% for stage I, 100% for stage IIa, 58% for stage IIb, 44% for stage III, and 0% for stage IV. The disease-free survival rates were 100%, 70%, 40%, 38%, and 0%, respectively. Histologic classification according to Müller-Hermelink found medullary tumors in 7 patients (10.1%), mixed in 18 (26.1%), organoid in 14 (20.3%), cortical in 11 (15.9%), well-differentiated thymic carcinoma in 14 (20.3%), and endocrine carcinoma in 5 (7.3%), with 10-year overall survival rates of 100%, 75%, 92%, 87.5%, 30%, and 0%, respectively, and 10-year disease-free survival rates of 100%, 100%, 77%, 75%, 37%, and 0%, respectively. Medullary, mixed, and well-differentiated organoid tumors were correlated with stage I and II, and well-differentiated thymic carcinoma and endocrine carcinoma with stage III and IV (p < 0.001). Multivariate analysis showed age, gender, myasthenia gravis, and postoperative adjuvant therapy not to be significant predictors of overall and disease-free survival after complete resection, whereas the Müller-Hermelink and Masaoka classifications were independent significant predictors for overall (p < 0.05) and disease-free survival (p < 0.004; p < 0.0001). CONCLUSIONS: The consideration of staging and histology in thymic tumors has the potential to improve recurrence prediction and patient selection for combined treatment modalities.

Functional assessment of chest wall integrity after methylmethacrylate reconstruction.

BACKGROUND: All patients with extensive resection of the anterolateral chest wall and the sternum followed by reconstruction with methylmethacrylate substitutes were assessed prospectively 6 months after the operation to delineate chest wall integrity with pulmonary function and cine-magnetic resonance imaging. METHODS: Twenty-six patients underwent chest wall reconstruction by use of methylmethacrylate between 1994 and 1998 due to primary tumors in 35%, metastases in 27%, T3 lung cancer in 19%, and debridement for radionecrosis and osteomyelitis in 19% of patients. Three to eight ribs were resected and additional sternum resection was performed in 39% of patients. RESULTS: There was no 30-day mortality. All patients were extubated after the operation without need for reintubation. Prosthesis dislocation occurred in 1 patient and infection in 2 patients during follow-up. Nineteen patients (73%) suffered no restrictions of daily activities. Clinical examination revealed normal shoulder girdle function in 77% of patients. There was no significant difference between preoperative and postoperative FEV1 (forced expiratory volume in 1 second) measurements in patients with lobectomy or wedge resections. Cinemagnetic resonance imaging revealed concordant chest wall movements during respiration in 92% of patients without paradoxical movements or implant dislocations being observed. CONCLUSIONS: Large defects of the anterolateral chest wall and sternum can be reconstructed efficiently with methylmethacrylate substitutes with minimal morbidity and excellent cosmetic and functional outcome.

A comparative evaluation of intrathoracic latissimus dorsi and serratus anterior muscle transposition.

BACKGROUND: Comparison of intrathoracic latissimus dorsi (LD) versus serratus anterior (SA) muscle transposition for treatment of infected spaces, broncho-pleural fistulae, and for prophylactic reinforcement of the mediastinum after extended resections following induction therapy. PATIENTS AND METHODS: Twenty LD and 17 SA transfers were performed for prophylactic reinforcement (11 LD; nine SA), and treatment of infections (nine LD; eight SA) from 1995 to 1998. RESULTS: The 30-day mortality was 0% following prophylactic reinforcement and 29% following treatment of infections (three LD; two SA). Prophylactic mediastinal reinforcement was successful in 11 of 11 patients with LD and nine of nine with SA transpositions, and treatment of infected spaces in eight of nine patients with LD and two of three with SA transfers. Morbidity requiring re-intervention consisted of flap necrosis (one LD), bleeding (one SA), and skin necrosis over a winged scapula (one SA). Subcutaneous seromas and chest wall complaints were more frequent following LD (45 and 36%, respectively) compared with SA transfers (29 and 27%, respectively), whereas impaired shoulder girdle function was more frequent after SA than after LD transfer (27 vs. 21%). CONCLUSION: Intrathoracic LD and SA muscle transpositions are both efficient for the prevention or control of infections following complex thoracic surgery, and are both associated with similar and acceptable morbidity and long-term sequelae.

[Parapneumonic pleural effusion, pleural empyema: medical and surgical aspects].

The following are essential for prophylaxis and treatment of empyema: antibiotic therapy for pneumonia, based on susceptibility results; early detection of parapneumonic effusions (decubitus radiograph, sonography); immediate diagnostic thoracocentesis if a parapneumonic effusion is large, increasing despite antibiotic therapy, if it is associated with clinical deterioration or if empyema is suspected; assessment of the stage of parapneumonic effusion or empyema (clinical signs, sonography, CT, laboratory parameters); immediate therapeutic thoracocentesis of frank empyema, in loculated empyema fibrinolytic agents may be used; early surgical intervention if conservative management fails; complete thoracoscopic decortication, if necessary open thoracotomy to assure complete reexpansion of the lung.

Morbidity and validity of the hemiclamshell approach for thoracic surgery.

OBJECTIVE: This is a prospective study to evaluate the indications and outcome of the hemiclamshell incision (longitudinal partial sternotomy combined with an antero-lateral thoracotomy) as used for a consecutive series of patients requiring surgery for various thoracic pathologies not ideally approached by postero-lateral thoracotomy, sternotomy or thoracoscopy. METHODS: All patients with a hemiclamshell incision performed between 1994 and 1998 were prospectively analyzed regarding indications, postoperative morbidity and outcome (clinical examination and pulmonary function testing) in order to validate this incision for thoracic surgery. RESULTS: 25 patients (15 men, 10 women) with an age ranging from 16 to 73 years (mean 43 years) underwent a hemiclamshell incision. The indications for the hemiclamshell approach were (1) chest trauma with massive hemorrhage requiring urgent access to the mediastinum and the ipsilateral pleural space (40%), (2) tumors of the anterior cervico-thoracic junction with suspicion of vascular involvement (28%) and (3) lesions involving both one chest cavity and the mediastinum (32%). The 30-day mortality was 8%. One patient suffered a sternal wound infection, mediastinitis and pleural empyema after a gun shot wound, whereas wound healing was uneventful in all other patients. Analgesic requirements for postoperative pain relief were not increased as compared to those following a standard thoracotomy. At 3 months normal sensitivity of the entire chest wall and intact shoulder girdle function was noted in 90% of the patients. Pulmonary function testing showed no restriction due to the hemiclamshell incision. CONCLUSIONS: The hemiclamshell incision is a useful approach in selected patients and does not cause more morbidity or long-term sequelae than a standard thoracotomy.

Bronchogenic cyst of the left lower lobe associated with severe hemoptysis.

Bronchogenic cysts result from congenital disorders, are often asymptomatic at diagnosis, but complications are not uncommon. We report the case of a 19-year-old woman with severe hemoptysis. This rare presentation of an intrapulmonary bronchogenic cyst should be considered as differential diagnosis in patients with cavernous lesion of a lobe. Surgery was performed as a diagnostic and therapeutic measure.

Left recurrent laryngeal nerve palsy associated with silicosis.

Left recurrent laryngeal nerve palsy usually results from invasion or compression of the nerve caused by diseases localized within the aortopulmonary window. This study reports the case of a 76-yr-old male with vocal cord paralysis due to lymph node involvement by silicosis. This rare entity was identified by video-mediastinoscopy, which revealed a granulomatous and fibrosed recurrent lymph node encasing the nerve. The nerve was dissected and released from scar tissues. Progressive clinical improvement was observed followed by total and durable recovery of the voice after 15 weeks follow-up.

Is the function of the serratus anterior muscle disturbed following division during a standard thoracotomy?

In a prospective study the functional results after dissection or preservation of the serratus anterior muscle in the postero-lateral standard thoracotomy were evaluated. In 14 patients of our clinic with dissection and suture and in 14 patients with preservation of the serratus muscle the muscle function was assessed and compared preoperatively, within the first two post-operative weeks, and three months after the operation by the same physiotherapists. The two groups were blinded in regard to age, original disease, and mode of intervention. We compared the wing position of the scapula in the sitting position and the positioning of the scapula at fixation of the shoulder joint in the sitting and in the supine position. Using a four-grade function assessment scheme, both groups obtained the same functional results. There was no seroma in either group. After 2.8 (2.5 to 3.0) years all the surviving patients described symmetric functional conditions. We therefore conclude that in order to achieve a better view of the operative field the serratus muscle may be dissected close to the origin if it is then readapted.

Isolated lung perfusion: single-pass system versus recirculating blood perfusion in pigs.

BACKGROUND: Cytostatic isolated lung perfusion has been advocated for treating pulmonary metastasis of soft tissue sarcoma. Different techniques of isolated lung perfusion have been developed. METHODS: Isolated lung perfusion with and without doxorubicin was performed on white pigs during 15 minutes either by a single-pass system (n = 7) or by a recirculating-blood perfusion system (n = 7). Three animals with endovenous drug application served as controls. Leakage was assessed using isotopic tracers. Perfusion-induced lung tissue injury was determined by postperfusion chest radiographs, by angiotensin-converting enzyme-to-protein ratio in the plasma and in the bronchioalveolar lavage fluid, and by wet-to-dry weight ratio and histologic examination of lung biopsy specimens at 20 and 50 minutes. Doxorubicin concentration in lung tissue and plasma was compared between the three study groups. RESULTS: All isolated lung perfusion studies were successfully performed without significant systemic leakage (< 0.6%). Wet-to-dry weight ratio was significantly lower after single-pass as compared with recirculating-blood perfusion and endovenous drug application at both time points (5.0 +/- 1.1 and 5.3 +/- 0.8 for single-pass versus 6.6 +/- 1.1 and 6.9 +/- 0.5 for recirculating-blood versus 6.6 +/- 0.2 and 5.9 +/- 0.7 for the control group, respectively; p < 0.05). Angiotensin-converting enzyme-to-protein plasma ratio in the single-pass group was significantly lower only at 20 minutes (6.3 +/- 2.4 versus 9.3 +/- 1.0 versus 9.7 +/- 1.9, respectively; p < 0.05) but not at 50 minutes. Angiotensin-converting enzyme-to-protein ratio in bronchoalveolar lavage fluid, histology of lung biopsy specimens, and chest radiographs did not differ significantly between the three groups. Doxorubicin lung tissue concentration was not significantly different after single-pass (17.5 micrograms/g) and recirculating-blood perfusion (21.9 micrograms/g), but was significantly higher than after endovenous drug application (3.0 micrograms/g; p < 0.01). CONCLUSIONS: Both isolated lung perfusion techniques resulted in a sixfold to sevenfold higher doxorubicin lung tissue concentration than after endovenous application. Isolated lung perfusion-induced lung injury was similar for both techniques, but recirculating-blood perfusion appeared to result in more acute lung injury and was technically more demanding than single-pass perfusion.

Cytostatic lung perfusion by use of an endovascular blood flow occlusion technique.

BACKGROUND: Different modalities of cytostatic lung perfusion were compared regarding plasma and tissue drug concentrations to assess the efficacy of an endovascular blood flow occlusion technique. METHODS: A cytostatic lung perfusion study with doxorubicin hydrochloride was performed on large white pigs (n = 12). Plasma and tissue concentrations of doxorubicin were compared for isolated lung perfusion with open cannulation (ILP), blood flow occlusion perfusion with open cannulation of the pulmonary artery alone (BFO), and intravenous drug administration (i.v.). In a fourth group, thoracotomy-free BFO perfusion was performed by endovascular balloon catheterization of the pulmonary artery (endovascular BFO). The 3 animals in this group were used to compare the doxorubicin-perfused pulmonary tissue with the contralateral nonperfused lobes after 1 month. RESULTS: The mean lung tissue doxorubicin concentration at the end of perfusion was 19.8 +/- 1.6 microg/g after ILP, 27.6 +/- 2.2 microg/g after BFO (p = not significant), and 3.0 +/- 0.8 microg/g after i.v. perfusion (p < 0.01). Whereas doxorubicin was not detectable in the plasma in the ILP group, concentrations ranged from not detectable to 0.44 microg/mL in the BFO group and from 0.31 to 0.84 microg/mL in the i.v. group (p < 0.05). Mean myocardial tissue concentration was not significantly different after BFO than i.v. perfusion (1.1 +/- 0.5 microg/g and 1.8 +/- 0.1 microg/g, respectively). In the endovascular BFO group, balloon-blocked pulmonary artery perfusion was successfully performed in all animals, and after 1 month, lung tissue showed no cytostatic-induced histologic changes. CONCLUSIONS: Compared with ILP, BFO cytostatic lung perfusion produced an insignificantly higher lung-tissue concentration, corresponding to a sixfold to ninefold higher level than after i.v. perfusion. Plasma drug levels during BFO perfusion were lower than during i.v. perfusion. Endovascular BFO may be a promising technique for repeated cytostatic lung perfusion.

[Surgical aspects of mycobacterioses. Evolution during the last 20 years].

INTRODUCTION: Tuberculosis remains one of the major infectious diseases. Its incidence has grown in immigrants and in immunosuppressed patients, and, moreover, cases of drug resistance are on the increase. The goal of this study was to analyze the implications of these new developments and surgical experience in our patients. METHODS: The cases of 104 patients with tuberculosis hospitalized between 1975 and 1995 were reviewed retrospectively. RESULTS: 22% of the patients (23/104) were immigrants. No HIV-positive patients were described but association with debilitating diseases was frequent. Diagnosis was chiefly by histology. The culture was positive in only 30/104 patients (29%). Drug resistance was seen in only one patient (1%). 72/104 patients (69.2%) presented with an infection of the pulmonary parenchyma, 21/104 (20.2%) with pleural tuberculosis including tuberculous empyema, 3/104 (2.9%) with tuberculosis of the chest wall and 8/104 (7.7%) with mediastinal tuberculosis. Surgery was performed in 84/104 patients (80.8%). The chief indications were suspected carcinoma in 39/84 cases (46.4%), destroyed lung in 11/84 (13.1%), empyema combined with bronchopleural fistula in 10/84 (11.9%), enlarged mediastinal lymph-nodes of unknown dignity in 7/84 (8.3%), recurrent pleural effusion in 5/84 (5.9%) and bronchial stenosis in 4/84 (4.8%). CONCLUSION: The number of surgical patients with tuberculosis has remained fairly stable over the last 20 years, but the proportion of immigrants has grown since 1990. Thoracoscopy is playing an increasingly important role in the diagnosis and surgical treatment of tuberculosis (recurrent pleural effusion, resection of peripheral pulmonary nodules turning out to be tuberculoma).

Long-term follow-up of patients with operative stabilisation of a flail chest.

The outcome is reported of patients after external chest wall stabilisation for respiratory insufficiency due to a traumatic flail chest. Since 1990, all patients with a flail chest causing respiratory insufficiency despite peridural analgesia and without further reason for prolonged mechanical ventilation underwent osteosynthesis of the chest wall using the AO-technique with 3.5 mm thick reconstruction plates, and were prospectively followed-up by use of clinical and radiological evaluation. 23 patients underwent external chest wall fixation between 1990 and 1996 and were followed for a mean time of 28 months. 2 patients died after the operation, giving a 30-day-survival rate of 91.3% 21 patients survived and were extubated and transferred to the ward after a mean time interval of 3.9 and 7.8 days, respectively. 95% of the survivors revealed a 100% working capacity at assessment and 86% returned to preoperative sports activities without complaining of chest wall or shoulder girdle pain or dysfunction. External chest wall fixation appears to be an attractive alternative to prolonged intubation and mechanical ventilation for selected patients with flail-chest respiratory insufficiency despite peridural analgesia, providing they do not require prolonged intubation for other reasons.
