Video-assisted thoracoscopic surgery in the diagnosis and treatment of chest diseases

Video-assisted thoracoscopic surgery (VATS) has been used recently in the diagnosis and management of thoracic diseases. In this report, VATS experience with 95 cases, focusing on indications, surgical procedures, complications, and failure rates, are reviewed. Over the past 5 years, 95 VATS procedures for diagnostic and therapeutic purposes were performed in 59 men and 36 women. The specific indications for VATS were lung biopsy for undiagnosed diffuse lung disease (48), mediastinal biopsy (12) and cyst (2), pleural effusion (10), empyema (5), pneumothorax and bullous lung disease (6), pericardial effusion (2) and cyst (2), paravertebral abscess (2), solitary pulmonary nodules (3), and thoracic trauma (3). In all patients, postoperative pain was controlled with non-narcotic analgesics and was measured according to the visual analogue scale (VAS). There was no surgical mortality. Postoperative nonfatal complications were seen in seven cases (7.5%). The overall median duration of chest tube drainage was 2.7 days and the mean postoperative hospital stay was 3 days. For diffuse lung disease, a tissue diagnosis was obtained in all the 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 therapeutic procedures was 100% after a mean follow-up of 12 months (range, 6-30 months). Conversion to thoracotomy was needed in six cases (6.6%). All patients scored postoperative pain <50% according to the VAS. Video-assisted thoracoscopic surgery should be considered as a procedure of choice, with exceptional results in the following chest diseases: (a) undiagnosed pleural effusions; (b) recurrent, post-traumatic, or complicated spontaneous pneumothorax; (c) stage II empyema; (d) accurate staging of lung cancer; (e) emergency traumatic injuries of the chest; (f) peripheral solitary pulmonary nodule <3 cm; and (g) lung biopsy for pulmonary diffuse disease.     

Video-assisted thoracoscopic surgery in the diagnosis of lung disease. The Cretan experience

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been recently utilised in the diagnosis and management of thoracic diseases. In this report we reviewed our VATS experience for biopsy of diffuse or localised lung diseases in 51 cases focusing on indications, operative procedures, complications or failures rates. PATIENTS AND METHODS: Over the last 5 years we performed 51 VATS procedures for diagnostic purposes in 32 men and 19 women. The specific indications for VATS were lung biopsy for undiagnosed diffuse or localised lung disease. In all patients the postoperative pain was controlled with the use of non-narcotic analgesics and was measured according the visual analogue scale (VAS). RESULTS: There was no operative mortality. Postoperative non-fatal complications were seen in 3 cases (6%). The overall median duration of chest tube drainage was 2 days and the mean postoperative stay 3 days. In the diffuse lung disease a tissue diagnosis was obtained in all the cases. Conversion to thoracotomy was needed in 1 case (2%), owing to extensive adhesions. All patients expressed a postoperative pain control effect of less than 50% of VAS. CONCLUSIONS: VATS should be considered as a safe and effective procedure, with low postoperative pain and morbidity. Should be recommended in patients who require a histological diagnosis of diffuse or localised lung diseases.     

Video-assisted thoracic surgery utilizing local anesthesia and sedation.

OBJECTIVE: Video-assisted thoracic surgery (VATS) is usually performed with general anesthesia and double-lumen endotracheal intubation, but minor procedures have been carried out with patients spontaneously breathing and with epidural or regional analgesia. We have broadened our indications for VATS utilizing purely local anesthesia and sedation. METHODS: The medical records of all patients undergoing VATS under local anesthesia and sedation at Geisinger Wyoming Valley Medical Center between 7/1/02 and 6/1/06 were reviewed. All procedures were performed in the operating room with patients in full lateral position; no patient had endotracheal intubation or epidural or nerve block analgesia. RESULTS: One hundred and fifteen patients, ranging in age from 21 to 88 years and in size from 40 to 172 kg, underwent 126 video-assisted thoracic operations: pleural biopsy/effusion drainage with or without talc 81, drainage of empyema 21, lung biopsy 18, evacuate hemothorax 3, pericardial window 2, biopsy chest wall mass 1. No patient required intubation or conversion to thoracotomy. Three patients who underwent lung biopsy died of their underlying disease (cytomegalovirus and pneumocystis, primary amyloidosis, metastatic cancer to contra-lateral lung) on postoperative days 18, 14, and 4, respectively. One patient developed transient renal insufficiency attributed to ketorolac. CONCLUSION: VATS utilizing local anesthesia and sedation is well tolerated, safe, and valuable for an increasing number of indications.     

Thoracoscopic Surgery for Pulmonary Tuberculosis

Tuberculosis historically was a major impetus for the development of thoracic surgery, and it remains a serious health problem of global proportion. Thoracoscopy was first introduced at the turn of this century for closed chest adhesiolysis as an adjunct to collapse therapy for treatment of tuberculosis. This indication became obsolete with the discovery of streptomycin during the 1940s; and for a long time since then thoracoscopy was used only sporadically for the diagnosis of pleural disease. However, over the last few years, modern video-assisted thoracoscopic surgery (VATS) has provided a new approach to the management of pulmonary tuberculosis. Over the last 5 years we have used VATS for diagnosis or treatment (or both) of 62 patients with pulmonary tuberculosis, including 20 pleural biopsies, 8 decortications, 17 wedge lung resections, 8 drainages of empyema, and 9 lobectomies. There was no surgical mortality, and complications were few. We conclude that VATS provides a safe, effective diagnostic modality (pleural biopsy, wedge resections) and therapeutic modality (decortications, drainage of empyema) for selected patients with pulmonary tuberculosis.     

Video thoracoscopic treatment in pleural empyema

BACKGROUND: To evaluate the possible role and the effectiveness of videothoracoscopy (VATS) in the treatment of pleural empyema. METHODS: Personal experience on 40 cases of pleural empyema treated by (VATS) during 5 years is reported. The underlying diseases were: pneumonia (32), pneumothorax (3), tuberculosis (2), abdominal diseases (2) and lung cancer (1). Before VATS at least one thoracentesis was performed to evaluate the characteristic of the pleural fluid. RESULTS: Due to complications related to thick pleural adhesions, in one case (2.5%) the procedure was converted to open surgery, while in the remaining 39 cases VATS was able to achieve a complete cleaning of the pleural space with re-expansion of the pulmonary parenchyma. The improvement of the clinical symptoms were observed after a mean period of 3.5 days (range: 1-12 days). Chest tube was removed in a mean period of 4.8 days (range: 3-11 days); five patients had prolonged air leak from 6 to 10 days after surgery. CONCLUSIONS: In conclusion we are of the opinion that VATS has to be considered a very important mean for the treatment of pleural empyema; its use in the fibrinopurulent phase of the disease should give very good results, while in the following phase its indications are controversial.     

Thoracoscopic surgery for diseases of the lung and pleura. Effectiveness, changing indications, and limitations.

OBJECTIVE: This study compared the results of video-assisted thoracic surgery (VATS) with thoracoscopic surgery (TS) for diseases of the lung and pleura. SUMMARY BACKGROUND DATA: No studies exist that compare the capabilities of VATS with advanced video systems and instrumentation to that of TS which has been done for 80 years. METHODS: A retrospective study was done comparing the effectiveness, indications, complications, and limitations of TS and VATS done for four categories of pleural disease: 1) pleural fluid problems, 2) diffuse lung disease, 3) lung masses, and 4) pneumothorax. The TS period was 1981-1990. The VATS period was 1991-1992. RESULTS: Eighty-nine consecutive TS cases and 64 consecutive VATS cases were reviewed. TS for resolution of pleural fluid problem was successful in 29 of 34 patients (85%), and VATS was successful in 18 of 20 (90%). Diffuse lung disease was diagnosed by TS using a cup biopsy on end-stage patients in respiratory failure. Since 1991 the diagnosis has been made with VATS using stapled wedge excisions on ambulatory patients. Surgical mortality decreased from 33% (10 of 30) to 9% (1 of 11) and the postoperative stay from 16.6 +/- 2.4 days to 8.2 +/- 2.2 days. Lung masses were diagnosed entirely by incisional biopsies using TS. Diagnosis was made in 83% and postoperative stay was 5.3 +/- 1.0 day. VATS allowed excisional biopsies permitting diagnosis in 100% with a postoperative stay of 3.0 +/- 0.2 days (p = 0.05). However, 20% required conversion to thoracotomy to locate the subpleural mass. TS was performed for spontaneous pneumothorax in only 26% (5 of 19) of the total pneumothorax cases, whereas, VATS was used for spontaneous pneumothorax in 67% (12 of 18). CONCLUSION: VATS has continued the effectiveness of TS for treating pleural fluid problems, has resulted in earlier surgical diagnostic intervention in diffuse lung disease and earlier therapeutic intervention in primary pneumothorax states, and has markedly expanded the safety, efficacy and indications for lung mass biopsy.     

Thoracic blastomycosis and empyema.

Blastomycosis is endemic in river valley areas of the southeastern and Midwestern United States. Pulmonary manifestations include chronic cough and pleuritic pain. Radiographic appearance of the infection can mimic bronchogenic lung carcinoma. Pleural effusion is rarely associated with this pulmonary infection, and empyema has not been previously reported. We report a case of pulmonary and pleural Blastomyces dermatitidis infection presenting as empyema thoracis. Diagnosis and treatment were attained with video-assisted thoracoscopic (VATS) pleural and lung biopsy and debridement.     

Videothoracosopy in diagnosis and surgical treatment of tuberculosis

From 1993 to May 2001, 795 psychiatric patients were treated including 563 with pleural effusion, 98 with multiple or solitary tuberculoma, 69 with tuberculous empyema, 14 with fibrotic-cavitary tuberculosis, 51 with disseminated tuberculosis. Mean age of the patients was 32 years. Survey of pleural cavity with pleural or lung biopsy was performed in 691 patients. In tuberculoma 14 lobectomies were performed, 23 patients underwent atypical lung resection without stapler (including with precise technique). Bilateral on-stage interventions were made in 32 patients. In empyema necrectomy and lung decortication were performed. 14 patients underwent videocavernoscopy with sequestrectomy and cavity drainage. In disseminated tuberculosis lung biopsy without staplers was usually performed. Aerohemostasis was achieved with plasma stream. One patient with empyema and one patient with pleural effusion died (lethality was 0.25%). Rate of postoperative complications was 7.5% in tuberculoma and 1.5% in disseminated tuberculosis. Conversion to thoracotomy was necessary in 3 (3%) patients with tuberculoma and 12 (17%) patients with empyema. Mean hospital stay was 4 days after diagnostic surgery and 7 days after lung resection. In pleural effusion diagnosis was verified in 98% cases, in disseminated tuberculosis--in 100%. Videothoracoscopy is the best diagnostic method for pleural effusion and disseminated forms of lung tuberculosis and operation of choice in tuberculoma and empyema. Videothoracoscopy in tuberculosis is highly effective and associates with low rate of postoperative complications and lethality.     

Palliative treatment of malignant pleural effusions by video-assisted thoracoscopic surgery

Malignant pleural effusion (MPE) are associated with significant morbidity. Prompt clinical evaluation followed by aggressive treatment often results in successful palliation. Video-assisted Thoracic Surgery (VATS) today can be employed in the diagnosis and treatment of idiopatic and known MPE. Between January 1994 and December 1998 233 MPE patients were treated with pleurodesis. 206 of them underwent tube thoracostomy and drainage alone followed by chemical pleurodesis. In 27 out of the 233 cases VATS management was applied. These patients had undiagnosed pleural effusions or recurrent MPE following failed previous drainage and pleurodesis. The cause of the effusion was breast cancer in 11 patients, lung cancer in 9, urogenital cancer in 3, mesothelioma in 2 and other in 2. VATS intervention was thoracoscopic exploration with biopsy and directed chemical sclerosis in undiagnosed MPE (19/27) and lysis of pleural adhesions with partial decortication and pleurodesis in recurrent effusions (8/27). VATS managements were successful 26/27 after mean follow up of 6 months. Had not mortality postoperatively and severe morbidity. Chest tubes were removed 1.5 +/- 0.5 days postoperatively and hospital stay were averaged 4 +/- 1 days. We concluded that VATS is a safety and effective way of managing selected patients with pleural effusions.

Video-Assisted Thoracic Surgery: Applications and Outcome

Thoracoscopy has been revived and expanded by recent improvements in endoscopic technology. The enhanced application and outcome of VATS (video assisted thoracic surgery) was retrospectively studied. Between 1992 and 1995, 82 patients underwent diagnostic thoracoscopy or interventional VATS. Indications included: shortness of breath with nonspecific x-ray abnormality (45%), pulmonary nodule (25%), pleural effusion/empyema (21%), pneumothorax (14%), and hemoptysis, chronic cough or lung consolidation (5%). Sixty-six (83%) of the procedures were completed thoracoscopically. Eight procedures (10%) required addition of a utility mini-thoracotomy and 6 procedures (7%) were converted to formal thoracotomy. Specific diagnostic and/or therapeutic applications of VATS included: inspection; lysis of adhesions; stapling of blebs; biopsy of lung, pleura, or mediastinal structures; drainage and decortication of empyema; mechanical and chemical pleurodesis; wedge resection; and segmental resection.Diagnosis was established and/or treatment completed in 95% of cases. Pathologic diagnoses included: interstitial pneumonitis (22%), cancer (19%), bullous disease (15%), cocci nodule (9%), and other (18%). There were twentytwo complications (28.9%) and four deaths (4.8%). All four deaths were from causes unrelated to the surgery. The most common complications were: residual pneumothorax or hydrothorax (7), failed pleurodesis (3), and prolonged incisional pain (2).The advantage of reduced chest wall and muscle trauma utilizing VATS as opposed to traditional thoracotomy translates to less patient discomfort. The excellent magnified visualization afforded by VATS offers the opportunity to successfully conduct diagnostic and therapeutic interventions in the chest with equal or better visibility. Our findings suggest that the applicability and success of VATS is greatly expanding and its complication rate is less or, at worst, comparable to traditional thoracotomy.     

Pulmonary paragonimiasis referred to the department of surgery.

We encountered seven cases of pulmonary paragonimiasis. All patients were adult males and 6 of 7 cases were over 50-year-old. Except for one case of chronic pleural empyema, 6 patients were referred to the department of surgery because of having a mass lesion on chest roentgenography which was indistinguishable from malignancy. Although 3 patients had mild hemoptysis, none of them showed classical rusty sputum. Only one patient had high level of eosinophilia, whereas others showed normal or marginal level of eosinophilia. Paragonimus eggs were detected in transbronchial lung biopsy specimens from 4 patients. All patients' sera were positive for Paragonimus-specific IgG antibody by immunodiagnosis. Surgical option was undergone only for one patient with chronic pleural empyema which was not cured by repeated chemotherapy. In the present series, we could avoid surgical options due to an erroneous diagnosis. When a pulmonary mass lesion or empyema is detected in patients who live in paragonimiasis endemic areas, paragonimiasis should always be included in the different diagnosis of lung diseases.

Comparative analysis of chest tube thoracostomy and video-assisted thoracoscopic surgery in empyema and parapneumonic effusion associated with pneumonia in children

BACKGROUND: Controversy exists regarding the optimal management strategy for children having empyema or parapneumonic effusion as a complication of pneumonia. We hypothesized that video-assisted thoracoscopic surgery (VATS)-assisted drainage of pleural fluid and debridement of the pleural space is superior to a chest tube alone in the management of these patients. We further identified predictive factors-namely, presentation, radiographic findings, antibiotic usage, and pleural fluid features-that could predict the need for VATS rather than primary chest tube drainage. METHODS: Forty-nine pediatric patients with pneumonia complicated by parapneumonic effusion or empyema treated at the Children's Hospital of Pittsburgh (1997-2003) were divided into three groups according to the therapy instituted: Primary chest tube, chest tube followed by VATS, or primary VATS. The groups were analyzed in terms of demographics and outcome, as judged by pleural fluid analysis and hospital resource utilization. Demographic and outcome data were compared among groups using one-way analysis of variance and the Student t-test. RESULTS: All groups were similar with respect to demographics and initial antibiotic usage. Patients undergoing primary VATS had a higher initial temperature, whereas radiographic findings of mediastinal shift and air bronchograms were more likely to be found in patients who underwent primary chest tube placement. Patients undergoing primary VATS demonstrated a significantly shorter total stay and lower hospital charges than the other groups. Forty percent of children started on chest tube therapy failed even with subsequent VATS, necessitating a significantly longer hospital course (18 +/- 3 vs. 11 +/- 0.8 days; p < 0.05) and higher hospital charges ($50,000 +/- 7,000 vs. $29,000 +/- 1000) than those having primary VATS. CONCLUSIONS: Patients treated by primary VATS had a shorter stay and lower hospital charges than patients treated by chest tube and antibiotic therapy alone. There were no demographic, physiologic, laboratory, or chest radiographic data that predicted the selection of VATS as an initial treatment. These data suggest a strategy of primary VATS as first-line treatment in the management of empyema or parapneumonic effusion as a complication of pneumonia in pediatric patients.

Simultaneous bilateral decortications via video-assisted thoracic surgery for bilateral empyema

IntroductionBilateral empyema is a rare and life-threatening condition that is difficult to treat. We herein report a case of bilateral empyema that was treated with simultaneous bilateral decortications via video-assisted thoracic surgery (VATS).Presentation of caseA 38-year-old female complained of chest pain, dyspnea, and high grade fever lasting two weeks. Computed tomography revealed bilateral notching pleural effusion and pneumonia with atelectasis. Bilateral thoracic drainage was performed. From the right chest, white pus was drained, and Streptococcus anginosus was identified. The left drainage fluid was serous, and no bacteria were identified. We diagnosed the patient with right empyema and left para-pneumonic effusion consequent to pneumonia. Because conservative therapies could not resolve the inflammatory findings, simultaneous bilateral VATS decortications were performed. Both thoracic cavities had loculated pleural effusion. In contrast to the preoperative findings, white pus was found in not only the right, but also the left thoracic cavity. She had an uncomplicated postoperative course and recovered.DiscussionBilateral empyema that has developed to the fibrinopleural phase is difficult to treat with drains alone. Bilateral VATS decortications helped to make a definitive diagnosis and treat both sides simultaneously.ConclusionSimultaneous bilateral VATS decortications should be considered as a feasible and effective procedure for bilateral empyema that is refractory to medical treatment.     

Video-assisted thoracic surgery (VATS) for children with pulmonary metastases from osteosarcoma

Background: Video-assisted thoracic surgery (VATS) may complement open thoracotomy in children with osteosarcoma requiring pulmonary metastasectomy. Methods: The records of children with metastatic pulmonary osteosarcoma considered for initial VATS intervention (n=9) were reviewed. Results: Two children did not have VATS exploration: one child with multiple bilateral nodules and another child with a deep parenchymal nodule. VATS provided diagnostic biopsy material in all cases when used (n=7). Two children had benign inflammatory lesions; four children had VATS-directed wedge resections of solitary malignant lesions; and one child had VATS biopsy of diffuse parenchymal and pleural pulmonary disease not amenable to resection. The mean operative time and hospital length of stay were 1.78 ± 0.54 h and 3.5 ± 1.8 days, respectively. There were two complications of VATS: bleeding in a child, requiring a transfusion, and a latent pneumothorax in a patient after removal of the chest tube. Conclusion: VATS is safe, serves as an excellent diagnostic modality, complements the open thoracotomy, and may enable the surgeon to avoid more extensive procedures in selected cases.Presented at the 48th Annual Cancer Symposium of The Society of Surgical Oncology, Boston, Massachusetts, March 23–26, 1995.     

Single access videothoracoscopic biopsy and talc pleurodesis in patients with malignant pleural effusion

Aim-Background

Recurrent pleural effusion is frequently observed in clinical experience and malignancy is one of the most frequent causes. Although it is generally necessary to prevent the recurrence of effusion in patients with disseminated neoplastic disease, in others, a diagnosis is required. The aim of this study was to determine the efficacy and safety of biopsy and pleurodesis by a single access videothoracoscopic approach.

Methods

We report a consecutive series of 20 patients (12 men, 8 women, aged 39 to 83 years) who underwent single access videothoracoscopy with pleural biopsy and talc pleurodesis for recurrent pleural effusion. In all cases, indication for the procedure was a recurrent pleural effusion, suspicious for malignancy. Videothoracoscopy was performed under general anaesthesia. For pleurodesis, an average of 8g of sterile talc powder was used. A six-month follow-up was completed for all patients, and efficacy was judged by clinical examination and chest X-ray.

Results

Diagnosis was obtained in all cases. In five cases, the diagnosis was a pleural involvement by breast cancer metastasis, and in four cases, a primary lung cancer was detected. Eight were mesotheliomas and one a parapneumonic collection. In two cases, an unknown-malignancy recurrent pleural effusion was observed. No deaths, talc-induced ARDS or malignant invasion of the scar occurred, but only a postoperative empyema and two subcutaneous emphysemas treated successfully without further operation.

Conclusions

Single access videothoracoscopic pleural biopsy and talc pleurodesis is a safe and effective method for the diagnosis and treatment of malignant pleural effusions.     

Mesothelioma – VATS biopsy and lung mobilization improves diagnosis and palliation

Objectives: Mesothelioma is an increasingly frequent malignancy in which diagnosis is often delayed and disease diagnosed at an advanced stage. Earlier diagnosis and therapeutic intervention that can control recurrent pleural effusion may improve outlook and survival. Methods: A prospective series of 25 patients in whom mesothelioma was suspected was referred for histological diagnosis by video assisted-thoracoscopy (VAT) after failure of other methods. At the same operative procedure drainage of pleural effusion, cytoreductive pleurectomy and lung mobilization was performed where possible. Complete follow-up was obtained. Results: All patients had a histological diagnosis (100%) from the material sent for biopsy. In 23 patients this was mesothelioma, in two patients chronic empyema. All patients undergoing drainage of effusion, cytoreductive pleurectomy and lung mobilization subsequently were diagnosed of having mesothelioma stages III to IV. Fifteen out of 21 who underwent lung mobilization had closure of the pleural space. Post operative air leak in this group was a mean of 5 days (2–12 days). Recurrent effusion occurred in only one patient. Eleven patients remain alive at 1–2 years post operation with no hospital admissions for recurrent pleural effusion. In the six out of 21 who did not have closure of the pleural space, one remained alive 9 months post surgery. Five died within 1–6 months of the procedure. The average number of further hospital admissions for repeat drainage of effusion was 3 (1–6). Conclusions: VATs provides adequate tissue for histological diagnosis where other methods fail. At the same operative sitting it provides a therapeutic intervention that allows drainage of effusion cytoreductive pleurectomy and lung mobilization in a significant number of cases. Where the pleural space can be closed this results in significantly fewer hospital admissions and appears to improve quality of life and length of survival. The price is a longer hospital stay due to prolonged air leak.     

Fast track video-assisted thoracic surgery

Video-assisted thoracic surgery (VATS) has been advocated as one of the primary diagnostic modalities for suspicious pulmonary nodules and diffuse interstitial lung disease. The aim of our study was to evaluate the cost and safety of VATS lung wedge resection(s) as an "overnight" hospital admission. We retrospectively reviewed all 37 charts of patients who underwent VATS wedge resections for these indications from August 1999 to April 2001. There was a slight female predominance with mean age of 56.8 years (range 33-88). Eighteen patients had interstitial disease and 19 patients had pulmonary nodules. The duration of chest tube drainage was one day in the majority (92%). Length of hospital admission was overnight in 70 per cent whereas 22 per cent remained two days. This latter group from the earlier period of the trial had characteristics identical to those of an overnight stay. This creates a potential overnight stay in 87 per cent. Five complications occurred in three patients, which extended the length of stay. No mortality was reported. The overall hospital charges for the overnight-stay VATS were nearly half the charges for the open thoracotomy counterpart. Diagnostic VATS wedge biopsy is a cost effective and safe procedure allowing an overnight hospital stay in the majority of cases.
