Postpneumonectomy empyema. The role of intrathoracic muscle transposition

Forty-five patients (36 male and nine female) were treated for postpneumonectomy empyema. All were initially managed with the first stage of the Clagett procedure (open pleural drainage). In 28 patients with associated bronchopleural fistula the fistula was closed and reinforced with muscle transposition at the time of open drainage. Seven patients had multiple flaps. The serratus anterior muscle was transposed in 28 patients, latissimus dorsi in 11, pectoralis major in four, pectoralis minor in one, and rectus abdominis in one patient. After the fistula was closed and the pleural cavity was clean, the second stage of the Clagett procedure (obliteration of the pleural cavity with antibiotic solution and closure of the open pleural window) was done. The number of operative procedures ranged from 1 to 19 (median 5.0). Length of hospitalization ranged from 4 to 137 days (median 34.0 days). There were six operative deaths (mortality rate 13.3%), none in the patients who had both stages of the Clagett procedure. Follow-up of the 39 operative survivors ranged from 2.1 to 90.2 months (median 21.8 months). Eighty-four percent of patients in whom the Clagett procedure was completed (26/31) had a healed chest wall with no evidence of recurrent infection. The bronchopleural fistula remained closed in 85.7% of patients (24/28). There were 19 late deaths, none related to postpneumonectomy empyema. We conclude that the Clagett procedure remains safe and effective in the management of postpneumonectomy empyema in the absence of bronchopleural fistula and that intrathoracic muscle transposition to reinforce the bronchial stump is an effective procedure in the control of postpneumonectomy-associated bronchopleural fistula.     

Pneumonectomy for unilateral destroyed lung with pulmonary hypertension due to systemic blood flow through broncho-pulmonary shunts.

OBJECTIVE: Three decades ago, a few patients with pulmonary hypertension and respiratory failure associated with a unilateral destroyed lung were reported to have been treated by a pneumonectomy. In the present study, we investigated the clinical features, operative indications, and results of four cases with pulmonary hypertension that underwent a pneumonectomy for a unilateral destroyed lung. METHODS: Four patients (three males, one female) with a destroyed lung and pulmonary hypertension (mean pulmonary arterial pressure >25 mmHg) were treated by a pneumonectomy between 1999 and 2002 at our institution. Their mean age was 59 years old (range 42-68 years). The underlying lung disease, Medical Research Council (MRC) dyspnea scale, respiratory function, arterial blood gas analysis, pulmonary arterial pressure, preoperative management, operative procedure, and postoperative course for each were reviewed retrospectively. RESULTS: The underlying lung disease that caused the destroyed lung was bronchiectasis in two patients, chronic empyema with bronchopleural fistula in one, and necrotizing pneumonia in one. The average mean pulmonary artery pressure was 33 mmHg (range 25-42 mmHg), which decreased to 27 mmHg (range 19-36 mmHg) after occlusion of the pulmonary artery in the affected lung. Following the pneumonectomy, the average mean pulmonary artery pressure was decreased to 17 mmHg (range 11-25 mmHg). Chronic inflammatory symptoms and functional impairments (showed by blood gas analysis, pulmonary arterial pressure, or MRC dyspnea scale) improved post-pneumonectomy. There was no operative death, though postoperative cardiorespiratory failure occurred in one patient. All patients were discharged from the hospital. CONCLUSIONS: We concluded that a pneumonectomy procedure may be indicated for selected patients with a unilateral destroyed lung and pulmonary hypertension due to systemic blood flow though broncho-pulmonary shunts.     

Thoracoplasty: current application to the infected pleural space

Thoracoplasty, once commonly used in the management of cavitary pulmonary disease, continues to find application in the obliteration of infected pleural spaces. This study reports a series of 13 patients receiving thoracoplasty between 1976 and 1989. Five patients had chronic apical empyema spaces without prior resection of lung tissue. Two of the empyemas were due to tuberculosis, two were due to atypical mycobacteria, and one was due to postpneumonic empyema. All patients had extensive destruction of upper lobe tissue. Eight patients had undergone prior pulmonary resection; 3 had persistent infected spaces in the early postoperative period, 3 had development of empyemas and bronchopleural fistulas late (5 to 19 years) after pulmonary resection, and 2 had postpneumonectomy empyema. All patients had rigid cavity walls preventing space obliteration by rib removal alone and required concomitant resection of the thickened pleura and intercostal muscle tissues. Bronchopleural fistulas were present in 11 patients and were closed with adjacent nonintercostal muscle. All patients survived and had successful obliteration of the infected spaces with acceptable physiological and cosmetic results. We conclude that thoracoplasty remains a useful procedure in the management of the infected pleural space in select patients.

Surgical Treatment of Cancer of the Thoracic Esophagus in Association With a Major Pulmonary Operation

Background: Pulmonary complications have been a major cause of mortality after operations for cancer of the thoracic esophagus. Although the risk involved in esophagectomy associated with a major pulmonary operation is expected to be high, it has seldom been evaluated on the basis of clinical experience.

Study Design: Of 408 patients who underwent esophagectomy, 8 had previously undergone major pulmonary operation (7 for tuberculosis and 1 for pulmonary cancer) and 10 underwent concurrent major pulmonary resection (7 for pulmonary invasion of esophageal cancer, 2 for synchronous pulmonary cancer, 1 for extensive bronchiectasia). All patients underwent systematic lymph node dissection for esophageal cancer, except one patient with mucosal cancer. To prevent postoperative complications, the operative approach and dissection procedures for esophageal cancer were modified according to the associated pulmonary operation and the extent of cancer invasion. All thoracotomies for esophagectomy were performed on the same side as the major pulmonary operation. Additional median sternotomy was performed when necessary. In the most recent 8 patients who underwent major pulmonary resection concurrent with esophagectomy, the bronchial stump was covered with a pedicle flap.

Results: Of the 18 patients who underwent pulmonary operation, postoperative complications developed in 13 of the 18 object patients, but none was fatal. The 3-year survival rate was 45%. All deaths were caused by esophageal cancer or another cancer.

Conclusions: Aggressive esophagectomy associated with major pulmonary operation is not contraindicated in patients with fair risk conditions. The operative procedures for esophagectomy should be appropriately modified to minimize the effect of the associated pulmonary operation. Special care should be taken with respect to the approach for mediastinal dissection and closure of the bronchial stump.     

Usefulness of thoracoscopic surgery in the diagnosis and management of thoracic diseases

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been recently utilised in the diagnosis and management of thoracic diseases. In this article we report our series of patients with established indications for VATS treatment. METHODS: Over the past 6 years we performed 104 VATS procedures for diagnostic and therapeutic purposes in 95 men and 39 women. The specific indications for VATS were: lung biopsy for undiagnosed diffuse lung disease, mediastinal biopsy and cysts, pleural effusion, empyema, pneumothorax and bullous lung disease, pericardial effusion and cyst, parvertebral abscess and solitary pulmonary nodules. RESULTS: There was no operative mortality. Postoperative non-fatal complications were seen in 7 cases. The overall median duration of chest tube drainage was 2.5 days and the mean postoperative stay 3 days. In diffuse lung disease a tissue diagnosis was obtained in all cases. Definitive diagnosis in the patients with undiagnosed pleural effusion was obtained in 90% of cases and the overall diagnostic rate was 98.5%. The success rate of the empyema (stage II) treatment and the therapeutic procedures is 100% after a mean follow-up of 12 months (range 6-30). Conversion to thoracotomy was needed in 6 cases. In all patients the postoperative pain was controlled with intake of non-narcotic analgesics with satisfactory results. CONCLUSIONS: VATS is worth considering and has been established as procedure of choice, with exceptional results in various chest diseases such as undiagnosed pleural effusions, recurrent, post-traumatic or complicated spontaneous pneumothorax, stage II empyema, accurate staging for lung cancer in the resection of peripheral solitary pulmonary nodule less than 3 cm, and lung biopsy for pulmonary diffuse disease.     

Clagett open-window thoracostomy in patients with empyema who had and had not undergone pneumonectomy

Patients with empyema not responding to simple chest-tube drainage and antibiotic therapy have been managed by a "Clagett"-type procedure that consists of open-window thoracostomy, antibiotic irrigation and closure of the window. The results of such treatment were reviewed. Of the 103 patients with empyema treated between 1967 and 1983, 41 underwent open-window thoracostomy. Twenty-eight (group 1) had empyema after pneumonectomy, 13 (group 2) did not; however, 9 of the 13 in group 2 had undergone lobectomy. The mean follow-up was 46 months for group 1 and 42 months for group 2. When surgical closure of the open-window thoracostomy was attempted, the success rate in group 1 was 85% for those without concomitant bronchopleural fistula, but only 36% in patients with a fistula. In group 2 the respective success rates were 50% and 57%. Unsuccessful closure resulted in chronic fistulas in four patients in each of the two groups. Six deaths in group 1 and two in group 2 were related to the original disease, but one was an operative death. These results demonstrate both the effectiveness and limitations of open-window thoracostomy in the management of these difficult cases.     

Primary lung cancer surgery after curative chemoradiotherapy for esophageal cancer patients

The safety and perioperative problems of primary lung cancer surgery after curative chemoradiotherapy (CRT) for thoracic esophageal cancer (EC) are controversial. We retrospectively evaluated six patients who had received curative CRT for EC from 2003 to 2009, in whom the lung nodule was identified as a primary lung cancer and who subsequently underwent pulmonary resection. The treatment for EC consisted of chemotherapy with cisplatin and 5-fluorouracil with concurrent curative thoracic radiotherapy (60 Gy). The median age at the surgery was 75 years (range 69-80 years). The median time from radiation to pulmonary resection was 26 months (range 7-70 months). All patients had a predicted postoperative forced expiratory volume in 1 s (FEV(1))% of >40% before lung surgery. The surgical difficulty involves mediastinal lymph node dissection following tissue fibrotic changes after thoracic radiation. Postoperative complications occurred in two patients, and included arrhythmia and empyema. The patient who developed empyema had a massive pericardial effusion after CRT and underwent pericardial fenestration at the time of pulmonary resection. There was no operative mortality. Lung cancer surgery after curative CRT for EC is feasible in carefully evaluated and selected patients.     

Concomitant cardiac and pulmonary operations

From 1965 through 1983, 43 patients underwent concomitant cardiac and pulmonary procedures at our institution. Most patients presented with cardiac symptoms and were incidentally found to have a roentgenographically indeterminate lung nodule. The pulmonary diagnosis of 38 patients was unknown preoperatively, and nine of these had a malignant lesion. All 43 cardiac procedures necessitated extracorporeal circulation. Thirty-one patients had benign pulmonary disease, 10 had bronchogenic carcinoma, and two had metastatic carcinoma. Concomitant pulmonary procedures were performed via median sternotomy and included single wedge resections in 32 patients, lobectomy in seven, multiple wedge resections in three, and pneumonectomy in one. Most resections were performed either before or after institution of bypass, without systemic anticoagulation. Of the two operative deaths (4.6%), one was related to intraparenchymal pulmonary hemorrhage after multiple wedge resections during anticoagulation. Thus, pulmonary resections performed during anticoagulation may be associated with increased risk and probably should be avoided. The second death was cardiac in origin and not related to pulmonary resection. The remaining patients recovered uneventfully. Definitive correction of both cardiac and pulmonary disease can be performed at one operation via a single incision with safety and benefit to the carefully selected patient.

Surgical treatment of pulmonary aspergilloma: current outcome

OBJECTIVE: This retrospective study was designed to confirm that aggressive pulmonary resection can provide effective long-term palliation of disease for patients with pulmonary aspergilloma. METHODS AND RESULTS: From 1959 to 1998, 84 patients underwent a total of 90 operations for treatment of pulmonary aspergilloma in the Marie-Lannelongue Hospital. The mean follow-up period was 9 years, and 83% of the patients were followed up for 5 years or until death, if the latter occurred earlier. The median age was 44 years. The most common indications were hemoptysis (66%) and sputum production (15%). Fifteen patients (18%) had no symptoms. Tuberculosis and lung abscess were the most common underlying causes of lung disease (65%). The procedures were 70 lobar or segmental resections, 8 cavernostomies, and 7 pneumonectomies. Five thoracoplasties were required after lobectomy (3 patients) or pneumonectomy (2 patients). The operative mortality rate was 4%. The major complications were bleeding (23 patients), prolonged air leak (31 patients), respiratory failure (10 patients), and empyema (5 patients). The actuarial survival curve showed 84% survival at 5 years and 74% survival at 10 years. During the first 2 years, death was related to the surgical procedure and the underlying disease. In contrast, 85% of the survivors had a good late result. CONCLUSION: Lobar resection in both the symptomatic and the asymptomatic patients was conducted in low-risk settings. For patients whose condition is unfit for pulmonary resection, cavernostomy may need to be undertaken despite the high operative risk. The better survival rate in this study may have been due to the selection of patients with better lung function and localized pulmonary disease.     

Single-stage complete muscle flap closure of the postpneumonectomy empyema space: a new method and possible solution to a disturbing complication

The management of postpneumonectomy empyema remains a disturbing and controversial area in the field of thoracic surgery. Many methods have been described and have had varying degrees of success. We present a series of 5 consecutive patients who underwent single-stage complete muscle flap closure of the pneumonectomy space with extrathoracic muscle flaps and omental grafts between October, 1981, and April, 1983. Two men and three women ranging from 37 years to 64 years old underwent such a closure from 3 to 13 months after original resection. Two patients had associated bronchopleural fistula. Prior to closure, 3 patients were managed with chest tubes and 2 with a modified Eloesser procedure. All operations were single-stage procedures, and all wounds closed primarily, with no permanent tubes or chest wall openings. There was no morbidity or mortality, and no subsequent operation has been required. Single-stage complete muscle flap closure of the postpneumonectomy empyema space has not been described previously, and we think it offers a possible solution to this potentially fatal complication.     

Pneumonectomy for complex aspergilloma: is it still dangerous?

OBJECTIVE: Pneumonectomy for complex aspergilloma is associated with high morbidity rates. This study aimed to improve the outcomes of this high-risk procedure by preventing postoperative complications. METHODS: Between April 1999 and December 2004, 25 patients underwent pulmonary resection for complex aspergilloma at our institution. Of these patients, 11 (44%) patients (9 males and 2 females) undergoing a pneumonectomy were reviewed in this study. Median age was 63 years (range, 36-71 years). Associated pulmonary diseases were cavities secondary to tuberculosis (n=6) and a post-lobectomy destroyed lung (n=5). All patients presented with symptoms, including hemoptysis (n=10) and purulent sputum (n=1). To minimize the risk of empyema and bronchopleural fistula, careful extrapleural dissection and bronchial stump reinforcement with a latissimus dorsi muscle flap were employed in all patients. Follow-up was completed on March 31, 2005. RESULTS: We performed six pneumonectomies (two right and four left) and five completion pneumonectomies (one right and four left). Operating time ranged from 361 to 781 min (median, 432 min). The median intraoperative blood loss was 1050 ml (range, 200-2910 ml). There was no operative mortality. No patient required re-exploration for postoperative hemorrhage. The major complications were empyema caused by anaerobic bacteria (n=1) and chylothorax (n=1). The treatment of both complications was successful. All patients were free from aspergillosis at the time of follow-up. CONCLUSIONS: Pneumonectomy for symptomatic complex aspergilloma can be performed with no mortality and low morbidity. The favorable results of this potentially deleterious procedure hinge on the efforts to prevent postoperative complications.     

Morbidity and mortality of operative intubation for malignant oesophageal obstruction

In 33 patients who underwent operative intubation of carcinoma of the oesophagus or gastric cardia, there were nine postoperative deaths (mortality 27%). Only 15 patients (46%) had no further operative procedure or anaesthetics, but their mean survival was only 3.7 months. Nine patients (27%) required a total of 17 procedures after the placement of their original tube. Operative intubation has a similar mortality to resection but the survival times are short. Whenever possible palliative resection or endoscopic intubation is to be recommended.     

Management of postpneumonectomy empyema and bronchopleural fistula

Empyema after pneumonectomy is often associated with a bronchopleural fistula (BDF) and has a significant mortality. Management options include systemic antibiotics and observation, adequate pleural drainage, appropriate parenteral antibiotics, removal of necrotic tissue, and obliteration of residual pleural space. We prefer to treat the empyema with the procedure originally described by Clagett and Geraci in 1963. They demonstrated that postpneumonectomy empyema could be successfully treated by open pleural drainage, frequent wet-to-dry dressing changes, and when the thorax was clean, secondary chest wall closure with obliteration of the pleural cavity with an antibiotic solution. Failure was most often caused by a persistent or recurrent fistula. Because of this, when a BPF is present, the original Clagett technique was modified to include transposition of a well-vascularized muscle to cover the stump at the time of open drainage to prevent further ischemia and necrosis. Our preference is intrathoracic transposition of extrathoracic skeletal muscle. The goals of therapy for postpneumonectomy empyema remain a healthy patient with a a healed chest wall and no evidence of drainage or infection. Excellent results can be obtained in more than 80% of patients by using the Clagett procedure and intrathoracic muscle transposition when a BPF is present.     

VIDEO-ASSISTED THORACOSCOPY

Recent advances in video-imaging and minimally invasive surgical instrumentation have expanded the role of thoracoscopy in the diagnosis and treatment of intrathoracic conditions. This prospective study describes the use of video-assisted thoracoscopy (VAT) in 100 consecutive patients. There were 70 males and 30 females with a mean age of 54.6. They underwent 103 VAT procedures with 41 thoracoscopic biopsies of lung, pleural, chest wall and mediastinal abnormalities, 32 for treatment of recurrent or persistent pneumothorax, 18 for thoracoscopic assessment of pulmonary and pleural tumours and 12 for thoracoscopic resection of peripheral lung lesions, chest wall, mediastinal and pleural tumours. Eighty-one patients had VAT procedures alone while the remaining 19 had VAT proceeding to thoracotomy. The mean operating time for VAT alone was 51 min (range 30–135min). There were no operative deaths. There were 8 significant complications from which patients recovered fully. Patients who underwent VAT alone were shown to have earlier postoperative mobilization, reduction in parenteral analgesic requirement and reduced length of hospital stay compared to patients undergoing additional thoracotomy. A telephone survey of patients on returning home showed that patients undergoing VAT alone returned to full activity earlier than those who had thoracotomy (mean 9.0 vs mean 19.4 days). This study confirms that VAT is a safe and effective procedure in the management of pulmonary, mediastinal and pleural disease and the treatment of persistent and recurrent pneumothorax. Its role in the resection of pulmonary malignancy remains to be defined.     

Total anomalous of pulmonary venous connection in infants less than 3 months old]

We examined the surgical results of total anomalous pulmonary venous connection (TAPVC) retrospectively in 6 infants, who were less than 3 months old and underwent a total repair at Ehime Prefectural Central Hospital between May, 1993 through May, 1998, in terms of the pre, peri, and postoperative management, the site of connection, and the surgical procedures. Aged at operation ranged from 1 day to 86 days (mean 39 days), and body weight ranged from 2.4 kg to 5.5 kg (mean 3.4 kg). All 6 patients had echocardiographic diagnosis and cardiac catheterization but one. In operative procedure, cut back method was done in a patient of paracardiac type of Darling's classification and posterior approach was used in total correction for 4 supracardiac and 1 infracardiac type. There were 3 hospital deaths who had poor conditions before operation, but no late deaths. Surgical results of TAPVC might have been improved with advances in non-invasive diagnosis by echocardiography, and pre and perioperative management. And we should take care of these patients of TAPVC in long term period to make sure that they have no pulmonary venous obstruction.     

Single ventricle repair in children with Down’s syndrome

Objective There is a paucity of information regarding appropriate management of children with Down’s syndrome and a functional single ventricle. We report the results of bidirectional superior cavopulmonary shunts in six patients with Down’s syndrome with a functional single ventricle. Methods Between January 1991 and December 2004, we identified six patients with Down’s syndrome among 263 who had undergone bidirectional superior cavopulmonary shunts (BCPSs). There were four males and two females. The age at BCPS ranged from 1 to 12 years (mean 4.3 ± 3.9 years), and body weight varied between 8.2 and 29.4 kg (mean 13.8 ± 7.8 kg). All six patients had an unbalanced complete atrioventricular septal defect, with right ventricular hypoplasia present in five and left ventricular hypoplasia in one. Results There were no operative deaths, but one case required takedown of the BCPS. Except for this case, postoperative courses were generally uneventful. The median duration of follow-up was 46 months (range 12–80 months). Only two of five survivors after BCPS underwent a subsequent Fontan procedure, and one of these patients died of pulmonary hypertension post-operatively. The remaining three patients appeared to have significant risk factors for the Fontan procedure due to severe common atrioventricular valve regurgitation or persistent pulmonary vascular obstructive disease, including one who has completely dropped out from the Fontan track. Conclusion Down’s syndrome is a risk factor in patients with functionally single ventricle due to persistent pulmonary hypertension and airway obstruction. These results show that single ventricle repair in patients with Down’s syndrome is accompanied with difficulties, and patient selection for the Fontan procedure should be done carefully.     

Surgical treatment of pulmonary aspergilloma and Aspergillus empyema

Twenty-four patients, 16 male and 8 female, underwent a total of 35 operations for pulmonary aspergillosis. Intrapulmonary aspergilloma was detected in 19, and Aspergillus empyema was present in 5. The major operative procedures performed were pneumonectomy in 2 patients, lobectomy in 8, segmentectomy in 1, cavernostomy in 4, and open-window thoracostomy in 5. The surgical results in 5 patients 70 years old or older were excellent. Empyema developed postoperatively in 2 patients who had undergone wedge resection of the lung or segmentectomy. Although resection involving the minimum extent possible is desirable in the treatment of intrapulmonary aspergilloma so as not to decrease lung function, it is dangerous to perform a limited procedure in the case of aspergilloma with an invasive character. In patients in poor general condition, cavernostomy followed by muscle flap plombage is recommended. For Aspergillus empyema, the primary procedure was open-window thoracostomy followed by plombage using chest wall muscle or omentum. We consider omental flap plombage to be superior to thoracoplasty in some respects for mycotic empyema, especially because it is a less extensive surgical procedure.     

Simultaneous bilateral total knee arthroplasty

Total knee arthroplasty (TKA) was performed simultaneously on both knees by two teams in a single procedure. The study population consisted of 74 patients (148 knee joints) with osteoarthritis (OA) or rheumatoid arthritis (RA). The peri- and postoperative results were compared with those in a group of 22 OA and RA patients (44 knee joints) who underwent staged operation during one hospital stay. Comparisons were made of functional score and range of motion (ROM) before and after operation, mean total blood loss, operative time, duration of hospital stay, and operative and postoperative complications. The simultaneous performance of bilateral procedures did not influence the functional score, ROM after operation, or mean intra- and postoperative blood loss. Nor was incidence of operative and postoperative complications increased compared with that in the staged operation group. The operative time in the simultaneous TKA group was significantly shorter than the time that would have been required had separate procedures been performed on both knees. Simultaneous bilateral TKA is beneficial for the patient.
