Coronary bypass grafting via minithoracotomy on the beating heart.

BACKGROUND: Recently the availability and the superiority of less invasive coronary artery bypass grafting on some selected groups of patients in the meaning of patient comfort and short hospital stay has been shown by some authors. We present here the clinical results of 40 patients operated on by minithoracotomy incision on the beating heart without using cardiopulmonary bypass mostly harvesting the left internal thoracic artery by videothoracoscopic assistance. METHODS: Between March 1996 and September 1996, 40 patients were operated on by harvesting the left internal thoracic artery mostly by video-assisted thoracoscopy and performing bypass through a minitoracotomy incision. Two patients in whom the procedure was switched to conventional technique were not included in this series. Nine of the patients were female and the rest were male. The mean age was 43.2 +/- 7. RESULTS: Left internal thoracic arteries were harvested by video-assisted thoracoscopy completely in 11 patients, incompletely in 24 patients (the harvesting was completed by direct vision afterwards), and under direct vision in 5 through a mini-anterior thoracotomy incision. Thirty-six patients received a bypass graft to left anterior descending coronary artery only, whereas 4 received a diagonal branch graft also. Left internal thoracic arteries were used to bypass the left anterior descending coronary artery directly in 38 patients. The left internal thoracic artery was injured in the middle portion during harvesting in 1 of the remaining 2 patients. The length was not enough in the other. A short saphenous vein graft was interposed between the left internal thoracic artery and the left anterior descending coronary artery in these 2 patients. There was no mortality. One patient had perioperative myocardial infarction. We did not see serious morbidity except one lung injury due to the trochar. CONCLUSIONS: The results obtained from our experience suggest that coronary artery bypass grafting by minithoracotomy could be applied effectively and safely without overwhelming additional risk to the patient. Furthermore, it has some advantages in reducing operative trauma and cost and also improving patient comfort.

Thoracoscopic retrieval of foreign bodies after penetrating chest trauma.

Video-assisted thoracic surgery or thoracoscopy has proved to be valuable in many settings in thoracic surgery. The use of video-assisted thoracic surgery in trauma has been limited, especially with respect to penetrating trauma. We report the use of thoracoscopy to remove intrathoracic fragments of glass and avert the need for a thoracotomy.

Thoracoscopic excision of a peripheral corticotropin-secreting pulmonary carcinoid tumor.

Bronchial carcinoid tumors are rare neuroendocrine neoplasms that arise from the Kulchitsky cells of the bronchial epithelium. These tumors can manifest as central carcinoid tumors, pulmonary carcinoid tumorlets, or peripheral carcinoid tumors. Occasionally, the peripheral carcinoid tumors produce corticotropin and result in Cushing's syndrome. Herein we report the first case of Cushing's syndrome associated with a peripheral pulmonary carcinoid tumor that was excised by video-assisted thoracoscopy. After excision, the patient had complete remission. Video-assisted thoracoscopy may be ideal for resecting a peripheral pulmonary carcinoid, especially in patients with debilitation but no evidence of metastasis.

Current concepts in the use of cavitary endoscopy in the evaluation and treatment of blunt and penetrating truncal injuries.

The use of thoracoscopy in the patient with penetrating injury to the thorax is in its infancy. Although it is used mainly for diagnosis, evidence suggests that it will become a therapeutic tool during the initial management of the traumatized patient and in the postinjury period (early evacuation of retained hemothorax and the treatment of empyema). Although its role in injuries to the superior chest is clear, its role has not been established in the evaluation of the diaphragm. Both laparoscopy and thoracoscopy offer advantages in this area that must be considered when contemplating diagnosis and treatment. Further studies help define the place of these procedures for injuries in the thoracoabdominal area. The indications for cavitary endoscopy after truncal injury are summarized in Table 2. It must be remembered that experience in this field is rapidly increasing, and indications will change with new studies and new technology.

Management of parapneumonic effusions.

When a patient with a parapneumonic pleural effusion is first evaluated, a therapeutic thoracentesis should be performed if more than a minimal amount of pleural fluid is present. Fluid obtained at the therapeutic thoracentesis should be gram-stained and cultured and analyzed for glucose, pH, LDH, white blood cells, and differential cell count. If the fluid cannot be drained because of loculations, a chest tube should be inserted and thrombolytic agents administered. If the pleural fluid recurs after the initial therapeutic thoracentesis but the patient is doing well clinically and the initial pleural fluid glucose was greater than 60 mg/dL; the pH, greater than 7.2; the LDH, less than three times the upper normal limit for serum and the cultures are negative; he or she can be observed. If one or more of the aforementioned criteria are not met, a second therapeutic thoracentesis should be performed, with repeat diagnostic evaluations of the pleural fluid. If the fluid recurs a second time, a small chest tube should be placed if the pleural fluid glucose and pH were lower and the LDH higher on the second thoracentesis than on the first thoracentesis. Patients with loculated-parapneumonic effusions should be treated with tube thoracostomy and thrombolytic agents. If drainage is incomplete, thoracoscopy, with breakdown of adhesions and debridement of the pleural space, is indicated. If thoracoscopy is unsuccessful, then thoracotomy, with decortication, is indicated unless the patient is too debilitated.

[Videothoracoscopy in the surgical treatment of pneumothorax: report of 46 cases].

We report our 3-years experience with video-thoracoscopy for pneumothorax. Forty-six endoscopies (34 men, 12 women; mean age 27 +/- 9 years) were performed. Patients were under general anesthesia and intubation was selective. The conventional approach was used, with 3 incisions through which the camera and endoscopic instruments were inserted. Results were good in 39 (84.7%) patients. Pneumothorax recurred in 4 (8.7%) patients during the 3 years of follow-up. Thoracotomy was performed in 3 patients, because of lack of lung expansion in 1, persistent leak in another and encapsulated empyema in the third. Mean hospital stay after surgery was 7.3 days. Video-thoracoscopy can be considered a good therapeutic alternative to thoracotomy in the surgical treatment of patients with pneumothorax.

[Current treatment of primary and secondary pneumothorax].

INTRODUCTION: The treatment of a primary or secondary spontaneous pneumothorax remains controversial and many therapeutic options exist. In the event of a first episode of pneumothorax, should the patient be treated by observation, aspiration or thoracic drainage? For patients undergoing a thoracoscopic intervention for a spontaneous pneumothorax which is the best technique to treat the lung and parietal pleura? What are the results of thoracoscopy compared to thoracotomy and are the costs comparable? PERSPECTIVES: The optimal treatment for a first episode of pneumothorax remains to be determined. As there are only a limited number of patients in the published randomised controlled studies only grade B or C recommendations can be given. This is also true for the treatment of the lung and parietal pleura during a thoracoscopic intervention. Most authors advise that an apical pleurectomy is performed. With regard to results and cost of thoracoscopy compared to thoracotomy, conflicting results have been published and definite conclusions cannot be drawn. CONCLUSION: As large randomised prospective studies are not available regarding the treatment of pneumothorax only grade B or C recommendations can be given.

Chronic sequels after thoracoscopic procedures for benign diseases.

OBJECTIVE: Chronic pains after lateral thoracotomy are present in up to 40% of cases. Chronic sequels after thoracoscopy are less common, but nevertheless, a cause for complaints by patients. Pain often reflects a recurrence of malign disease. For this reason, we only investigated patients with benign disease. METHODS: We retrospectively investigated the incidence of chronic sequels in a consecutive series of 161 patients who underwent thoracoscopy for benign disease and were not converted to an open procedure. The data from all 144 patients, contactable at the time of investigation, who were at least 2 months postsurgery, were analyzed. RESULTS: Chronic sequels were present in an overall of 31.4% of patients. Patients complained of chronic pain (20.1%), numbness distal to the incision sites (16.9%) and disaesthesia (8.3%). Painkillers are taken on a regular basis by 82.8% of patients with chronic pain. The use of Staplers, as well as the number of drains (1 vs. 2) used, were statistically significant (P>0.05) for chronic sequels. All other investigated factors, such as sex, age, and length of drainage, were not significantly different in the two groups. CONCLUSION: The thoracoscopic approach is not likely to impact on the prevalence of long-term postthoracotomy sequels, and therefore, further strengths are necessary to reduce this number.

Thoracoscopic pleurodesis for prolonged (or intractable) air leak after lung resection.

Air leaks are common after lung resection, and normally seal with conservative therapy. Re-thoracotomy is rarely indicated. We present three patients with prolonged air leak and partial pneumothorax treated by thoracoscopy. Complete lung re-expansion followed immediately. Postoperative air leak was minimal. The chest tubes were removed after three or four days. Complete division of adhesions and sealing of the leak(s) are essential. Thoracoscopy may be the method of choice for prolonged air leak unresponding to conservative therapy provided the bronchial stump or suture have been verified by endoscopy.

Medical thoracoscopic lung biopsy in interstitial lung disease: a prospective study of biopsy quality.

The aim of this study was to analyse the quality and diagnostic value of lung biopsies for the diagnosis of interstitial lung disease (ILD), taken with diathermy coagulation cup forceps during medical thoracoscopy. Patients with ILD, not specified after thorough clinical assessment, high-resolution CT (HRCT), bronchoalveolar lavage and transbronchial biopsy, were studied. Medical thoracoscopy was performed in an endoscopy suite under neuroleptic anaesthesia with spontaneous ventilation. Biopsy specimens were analysed prospectively by one lung pathologist blinded to the clinical findings. Over 2 yrs, 118 samples were analysed from 24 consecutive patients. A good quality biopsy was obtained in 23 patients, and 78% of the samples were of good quality. Biopsy findings plus clinical and HRCT data revealed a relevant diagnosis in 18 patients and some diagnostic clues in four patients, for whom further examinations were needed. No major complications occurred. Chest tube drainage averaged 5.3+/-4.7 days, and was related to the total lung capacity (p=0.008), which mirrors the severity of ILD. Separate sampling of biopsies from different lobes proved to be useful in one third of the cases. In conclusion, lung biopsy sampling can be performed safely by interventional pulmonary endoscopists and has a good diagnostic yield in interstitial lung disease of unknown origin.

Thoracoscopic talc pleurodesis for malignant pleural effusion.

BACKGROUND: Malignant pleural effusion (MPE) is a common and distressing condition at the end of life for many patients with disseminated cancer. The challenge for the surgeon lies in managing this problem in order to deliver the most effective palliation with the least impact on the limited time available to these patients. METHODS: Herein is reported a retrospective review of outcomes for a consecutive series of 66 MPE (61 patients) treated over a 5-year period from 1995 to 2000. A standard operative technique involving a single-lung anaesthetic and two-port thoracoscopy was employed. Outcomes were determined by contacting the referring practitioner or the patients themselves. Principal outcome measures included time to recurrence of the effusion and survival. RESULTS: Complete follow up was achieved for 60 MPE (55 patients; five of whom were treated for metachronous, bilateral disease). The three most common primary sites were breast, lung and mesothelial tissue. The planned procedure was not completed in two cases due to encasement of the underlying lung by tumour. Primary failure (immediate recurrence of the effusion) occurred in six cases. Delayed recurrence of the effusion occurred in a further 23 MPE resulting in complete control in 31 cases (52%) until death. Overall median survival was 220 days and the 30-day mortality was 0. CONCLUSIONS: Complete and permanent control of a malignant effusion is difficult to achieve. Management based on thoracoscopy and talc insufflation produces satisfactory results with an acceptable morbidity and no early mortality. The ability to inspect the pleural space, break down adhesions and completely drain pockets of fluid to achieve complete lung expansion probably contributes to this.

Anaesthetic implications of thoracoscopic surgery in children.

As the equipment and technique have improved, minimally invasive surgery is being applied to younger and younger children. With the advent of this valuable surgical technique, there are also specific modifications necessary in the anaesthetic technique. When considering the anaesthetic implications of these patients, one must account for both the patient's underlying status as well as physiological derangements induced by the surgical procedure. The following article attempts to address and review the specific anaesthetic implications of thoracoscopic procedures in neonates, infants, and children including the preoperative evaluation, intraoperative care and monitoring, and postoperative issues including analgesia. The techniques of one-lung anaesthesia, commonly required for thoracoscopy, are reviewed as well as consideration of the adverse effects which can occur during thoracoscopy including inadvertent intravascular CO2 embolism.

Thoracic computed tomography in patients with suspected malignant pleural effusions.

AIM: To assess the role of contrast-enhanced computed tomography (CT) prospectively in patients with suspected malignant pleural effusions. MATERIALS AND METHODS: Forty consecutive patients referred for the investigation of a suspected malignant pleural effusion had contrast-enhanced thoracic CT, thoracoscopy, thoraco-centesis and pleural biopsy, either percutaneously or at thoracoscopy. Final diagnoses were based on histopathological or cytological analysis (n = 30), autopsy findings (n = 3) or clinical follow-up (n = 7). The pleural surfaces were classified at contrast-enhanced CT as normal or abnormal and, if abnormal, as benign or malignant in appearance using previously established CT criteria for malignant pleural thickening by two observers unaware of the pathological diagnosis. RESULTS: Pleural effusions were malignant in 32 patients and benign in eight patients. Pleural surfaces assessed at CT showed features of malignancy in 27 out of 32 patients with a malignant effusion (sensitivity 84%, specificity 100%). Overall, CT appearances indicated the presence of malignancy in 28 of 32 (87%) patients. All eight patients with benign pleural disease were correctly diagnosed by CT. CONCLUSION: Contrast-enhanced CT is of value in patients with suspected malignant pleural effusions. The previously established criteria for malignant pleural thickening of nodularity, irregularity and pleural thickness >1 cm are reliable in the presence of a pleural effusion.

Thoracoscopic resection of mediastinal masses in infants and children: an evaluation of technique and results.

BACKGROUND: Thoracoscopy has been accepted as a technique in pediatric surgery for diagnosis of thoracic pathology, but there has been little experience using it as a therapeutic modality as well. The purpose of this report is to describe and critically evaluate a 7-year experience with thoracoscopic diagnosis and resection of mediastinal masses in infants and children. METHODS: From February 1993 to June 2000, 39 patients presented with mediastinal masses and no tissue diagnosis. Age ranged from 5 months to 18 years old and weight from 3.6 to 110 kg. Twelve children had anterior mediastinal masses, 27 posterior. The patients were positioned in a modified prone or supine position, and single lung ventilation was performed on the contralateral side. Three or 4 valved trocars were utilized with 3 and 5 mm instrumentation. RESULTS: A total of 38 of 39 procedures were completed successfully endoscopically. The procedure in 1 patient with a sarcoma was converted to thoracotomy because of extensive disease. Operating times ranged from 20 to 185 minutes. Diagnosis was obtained in all cases, and complete excision was performed in 33. All children were extubated in the operating room; 8 chest tubes were placed but removed within 24 hours. Hospital stay ranged from 12 hours to 4 days. Pathology included 12 foregut duplications, 7 ganglioneuromas, 6 neuroblastomas, 6 lymphomas, 3 teratomas, 2 sarcomas, and 3 other lesions. CONCLUSION: Thoracoscopy is a safe and effective method to evaluate, biopsy, and in most cases resect lesions of the anterior and posterior mediastinum in infants and children.

Successful thoracoscopic lung biopsy in children utilizing preoperative CT-guided localization.

BACKGROUND/PURPOSE: Although thoracoscopy in children is a well-accepted technique, there are limitations to this approach. Small lung nodules or those not located on the pleural surface often require an open thoracotomy. The purpose of this report is to evaluate the utility of computed tomography (CT) guided needle localization of lung nodules in children followed by thoracoscopic resection. METHODS: From 1997 to 2000, 13 thoracoscopic procedures were performed on 12 children who presented with small pulmonary nodules (<1 cm) or nodules deep to the pleural surface. Preoperative needle localization was performed by injecting methylene blue under CT guidance. Patients then were taken directly to the operating room for thoracoscopic resection. RESULTS: All 13 procedures were completed successfully thoracoscopically. Twelve yielded diagnostic pathologic findings as well as therapeutic resections in 7. All patients underwent extubation in the operating room, and chest tubes were removed within 36 hours. No thoracotomies were performed, and there were no complications. CONCLUSIONS: Preoperative localization utilizing CT guidance is safe and beneficial in children with pulmonary nodules less than 1 cm in size and those located deep to the pleural surface. This technique allows the surgeon to perform thoracoscopy for diagnosis and therapeutic resection of these lesions rather than submitting patients to the morbidity of a thoracotomy.

Videothoracoscopy in the diagnosis and treatment of malignant pleural mesothelioma with associated pleural effusions.

Between 1985 and 1994 46 of 662 patients examined by thoracoscopy for secondary malignant pleural effusion were diagnosed to have diffuse malignant pleural mesothelioma. Mean patient age was 59 years, with a male: female ratio of 5:1. The right hemithorax was more frequently involved than the left (55% versus 45%). Pleural fluid cytology revealed malignancy in 61.5% of cases. All patients were treated thoracoscopically by talc pleurodesis. Mean patients survival was 9.4 months. Survival after one, two, and 5 years was 37.5%, 12.5%, and 5%, respectively. The characteristics of mesothelioma and pleural effusion evident in thoracoscopy and their diagnostic relevance are discussed. We suggest talc instillation as the sole therapeutic maneuver in evolutioned cases, since the literature and our own experience indicate that survival is not significantly prolonged by more aggressive surgical approaches.

Prerequisites, indications, and techniques of video-assisted thoracoscopic surgery.

During the last two years video-assisted operative thoracoscopy has introduced new impetus into thoracic surgery. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. The prerequisites, instruments, and operative techniques are discussed. In oncological thoracic surgery it still remains to be verified whether the criteria of radicality are fulfilled by this new technique. Using video-assisted operative thoracoscopy, we have successfully operated on 209 patients with the following indications: recurrent pneumothorax (n = 94), interstitial lung disease (n = 25), coin lesion (n = 20), pleural effusion (n = 17), hyperhidrosis (n = 14), mediastinal tumor or lymphoma (n = 10), thoracic empyema (n = 9), bullous emphysema (n = 8), pleural tumor (n = 5), hematothorax (n = 3), malignant pericardial effusion (n = 3), and chylothorax (n = 1). The advantages of this minimally traumatizing operating technique lie in a better view of the operative site, the objectively measurable reduction in postoperative restriction, less pain, earlier postoperative mobilization, and shorter hospital stay. This operating technique, in addition to being sparing, requires markedly less time than a thoracotomy. The disadvantages are the two-dimensional monitor picture and, especially, the loss of palpation.

Thoracoscopic wedge resection of peripheral lung lesions.

The increasing experience with minimally invasive surgery and advances in endoscopic equipment have expanded the role of thoracoscopy to include thoracoscopic pulmonary resections. In 11 patients we have evaluated the technical feasibility of thoracoscopic wedge resection of single peripheral lung lesions. In 8 patients the lesion could be exactly identified by thoracoscopy and be effectively resected using an automatic endoscopic stapler. All lesions were located within the outer third of the lung parenchyma with a maximum distance of 1.4 cm between lesion and visceral pleura. Mean diameter of the nodules was 1.9 cm and ranged from 1.0 to 4.1 cm. Histological analysis revealed completely excised tuberculomas in 4, carcinomas in 2, hamartoma in 1, and localised fibrosis in one patient. In 3 patients the thoracoscopic approach was unsuccessful because of difficulty in identifying the lesion or impossibility of achieving a reliable assessment of the intraparenchymal extension of the tumor. In conclusion, thoracoscopic wedge resection is helpful for the diagnostic and therapeutic management of peripheral lung lesions in carefully selected patients. Continued experience is necessary to be able to establish reliable criteria to assess which types of lung lesion can be excised safely and effectively by videothoracoscopy.
