Incidence of arrhythmias after thoracic surgery: thoracotomy versus video-assisted thoracoscopy.

PURPOSE: Atrial arrhythmias, especially supraventricular tachycardia (SVT) and atrial fibrillation, are common after thoracotomy and lung surgery. There are few existing data on the incidence of postoperative arrhythmias after video-assisted thoracoscopy (VAT). The purpose of the present investigation was to retrospectively determine the incidence of postoperative arrhythmias in patients who underwent VAT compared with those who underwent thoracotomy, and which factors are associated with an increased risk for arrhythmias in both groups. DESIGN: A retrospective investigation. SETTING: A metropolitan university hospital. PARTICIPANTS: The medical records of 124 patients who underwent thoracotomy and 81 patients who underwent VAT over a 2-year period were reviewed. MEASUREMENTS AND MAIN RESULTS: There was a 17% incidence of atrial arrhythmias after thoracotomy and 10% after VAT, but the difference was not statistically significant. In both groups, atrial fibrillation was the most common atrial arrhythmia. CONCLUSION: Patients receiving digoxin were at higher risk for postoperative arrhythmias. Patients older than 65 years were at risk for arrhythmias after thoracotomy and patients older than 80 years were at risk for arrhythmias after VAT. Patients who had postoperative arrhythmias had prolonged hospital stays compared with patients who did not have arrhythmias.

Anesthetic considerations for laser, laparoscopy, and thoracoscopy procedures.

Laser surgery and laparoscopy are two relatively new surgical techniques gaining popularity in veterinary medicine, which require special consideration when being performed on the anesthetized patient. For laser surgery, consideration must be given to the possibility of atmospheric contamination, inappropriate energy transfer, eye injury, perforation of a vessel or anatomic structure, perforation of the endotracheal tube, and fire. The primary concern with laparoscopy and thoracoscopy is the creation of a pneumoperitoneum or pneumothorax, which can result in (1) hypercarbia and inadequate ventilation, (2) poor cardiac output and systemic blood pressure, and (3) gas embolism. To minimize complications, patients should be placed on positive pressure ventilation, be well hydrated before and during the procedure, and be thoroughly monitored (ECG, capnography, pulse oximetry.

Laparoscopy or thoracoscopy for achalasia.

Achalasia is an esophageal motor disorder of unknown etiology. Typical manometric findings include aperistalsis of the esophageal body coupled with elevated pressure and incomplete relaxation of the lower esophageal sphincter during swallowing. Medical treatments consist of pneumatic dilatation or injections of botulinum toxin. Surgical treatment consists of Heller's myotomy with or without an antireflux procedure. Relief of dysphagia symptoms can be achieved in 85% to 94% of patients undergoing surgical treatment. In the past decade, the minimally invasive approach for the treatment of achalasia has been proven feasible, safe, and effective. We review the role of thoracoscopy and laparoscopy and address controversies in the management of patients with achalasia.

Video-assisted thoracoscopy for closure of a bronchial stump fistula.

It is thought that thoracoscopic closure of a bronchial stump fistula is beyond the capabilities of current thoracoscopic techniques. We describe the successful use of thoracoscopy in the therapy of a late right main bronchial stump dehiscence after pneumonectomy and chemotherapy of a stage IIIA adenocarcinoma. We clipped the fistula with a Multifire Endo Hernia Stapler (Auto Suture) and we obtained intraoperative airtight closure of the fistula.

Diagnostic thoracoscopy in pleuro-pulmonary infiltrates without pleural effusion.

In seven patients with pleuro-pulmonary infiltrates without pleural effusion, an artificial pneumothorax was induced, followed by diagnostic thoracoscopy, as the first and only invasive investigation; in all cases the diagnosis was confirmed by this simple procedure. The method has a low mortality correlated to other alternative diagnostic methods.

Combined video-assisted mediastinoscopy and thoracoscopy in the management of lung cancer: a five-year experience.

OBJECTIVE: The aim of this study was to assess the usefulness of combined video-assisted mediastinoscopy (VM) and video-assisted thoracoscopy (VT) in the management of patients with lung cancer. METHODS: A prospective observational study was performed over a 5-year period. Indications for combined VM and VT included inconclusive findings from imaging techniques concerning locoregional extension and resectability; possible involvement of different structures not accessible to a single procedure; and failure to obtain a histologic diagnosis with a single technique. RESULTS: An indication for combined exploration was established in 30 patients, representing 2.6% of all the patients referred to us for diagnosis, staging, and/or resection of lung cancer. Combined VM and VT was completed in 28 patients, as pleural carcinosis was found at VT in 2 cases. There was no mortality or morbidity in our series. Histologic diagnosis was obtained in 12/13 patients without preoperative histologic typing. In all the evaluated patients, combined VM and VT was useful in clinical decision-making, leading to immediate surgery (n=10), induction treatments (n=8), or nonsurgical therapy (n=12). Among the patients who underwent immediate surgery, combined VM and VT never failed to assess the T factor. The N factor was correctly evaluated in 8/10 patients, and in 2 patients it failed to recognize a minimal N2 disease. CONCLUSION: Combined VM and VT is a safe and useful tool in the management of selected patients with lung neoplasms. Both the extent of primary tumor and the possible intrathoracic spread can be thoroughly evaluated.

Early evacuation of clotted blood in hemothorax using thoracoscopy: case reports.

Hemothorax complicated by clotting of the blood is traditionally treated with thoracotomy. Successful treatment using early thoracoscopy in two patients is described. A third patient, in whom thoracoscopic evacuation failed, is also discussed. Early timing of the procedure appears to enhance the opportunity for adequate drainage of the thorax with lung re-expansion.

Thoracoscopy and transplantation: a new attractive tool.

BACKGROUND: Transplanted patients on immunosuppressive treatment have an increased risk of infections or neoplasms. Transplantation candidates with infection or a suspected malignancy are excluded from transplantation. In patients already transplanted, thoracoscopy can resolve complications or treat the pulmonary pathology without compromising the precarious existing reactive equilibrium. These patients require an approach that is as least traumatic as possible. METHODS: From September 1991 to December 2000, of 2068 videothoracoscopic procedures carried out at our hospital, 2 were in patients who had undergone transplantation and 3 in candidates for kidney, liver, and bone marrow transplantation. Starting from our personal experience in videothoracoscopy as a diagnostic and therapeutic approach, the possibilities of the method in the field of transplantation are reported by a review of the literature carried out by consulting the reference systems of the most important data banks. CONCLUSIONS: In our experience, videothoracoscopy had a major impact on the management of candidates for transplant, because it allowed us to rule out or treat conditions that would have determined exclusion from a transplant program. In transplanted patients, videothoracoscopy allows a correct diagnosis and treatment with minimal trauma.

Thoracoscopy and video-assisted thoracic surgery.

Thoracoscopy is an old technique that has been recently revived with the development of video-endoscopic technology. Video-assisted thoracic surgery (VATS) is now an established surgical approach with proven benefits in the management of pleural diseases. It has been found to be particularly useful in establishing the diagnosis of pleural metastasis with an option for treatment. It also has an established therapeutic role in the management of the fibrinopurulent phase of empyema and the treatment of hemothorax. The technique is still continually evolving, and refinement of instrumentation promises to further reduce surgical trauma in selected procedures.

Real time imaging and quantitative evaluation of the emphysematous lung by infrared thoracoscopy in experimental dogs.

To accurately excise emphysematous lung tissue in volume reduction surgery, we projected a digitally analyzed excision line on the real time image obtained by infrared thoracoscopy (IRT) with indocyanine green (ICG) intravenous injection. Emphysema was created in the canine lung by intrabronchial injection of elastase. We examined the emphysematous lung by IRT after intravenous injection of ICG. A digitized static image was obtained and analyzed in real time during the surgery. The color densities on the image were measured and the color density ratios (CDRs) calculated. We resected lung areas where the CDR was 1.0 or less. Resected and residual lung areas were examined microscopically. Microscopically, areas displayed as white by IRT with intravenous injection of ICG were emphysematous, and areas displayed as blue were normal. Areas with a CDR of 1.0 or less were emphysematous, and we were able to determine an appropriate excision line by connecting sample points with a CDR of 1.0. Use of digital image analysis combined with IRT after ICG injection enabled us to remove emphysematous regions accurately.

Treatment of complicated spontaneous pneumothorax by simple talc pleurodesis under thoracoscopy and local anaesthesia.

BACKGROUND: Complicated (recurring or persistent) spontaneous pneumothorax requires treatment either by talc pleurodesis with bullae electrocoagulation or, more aggressively, by thoracotomy or video-assisted thoracoscopic surgery. However, the relative merits of bullectomy, pleurectomy, and pleurodesis have not yet been established in the treatment of spontaneous pneumothorax. METHODS: The complications, duration of drainage, length of hospital stay, and immediate and long term success rate of treating complicated spontaneous pneumothorax with talc pleurodesis under local anaesthesia supplemented with nitrous oxide were studied. RESULTS: Talc pleurodesis was performed in 93 patients without serious complication (two benign arrhythmias, two subcutaneous emphysema, two pneumonia, one bronchospasm). The procedure was immediately successful in 90 patients (97%) with a median duration of drainage of five days (range 2-40) and a median length of hospital stay of 5.2 days (range 3-40). After a mean follow up duration of 5.1 (range 1-9.4) years in 84 cases the long term success rate was 95%, although six cases developed a small localised recurrence of spontaneous pneumothorax which did not require further surgery. Macroscopic staging at thoracoscopy was only carried out in the last 59 cases of whom 10 (17%) had bullae with a diameter of > 2 cm. In this group of patients the risk of definitive failure requiring surgery was significantly higher than in those patients without such bullae (odds ratio 7; confidence interval 3.7 to 13.3; p = 0.03), although eight of these patients did not require thoracotomy. Total lung capacity was reduced immediately after talc pleurodesis (mean (SD) 75 (23)% predicted at 10 days) but had improved to 95 (14)% predicted at 12 months. CONCLUSIONS: This study shows that simple thoracoscopic talc pleurodesis under local anaesthesia is a safe and effective treatment for complicated spontaneous pneumothorax. However, patients with bullae of > 2 cm in diameter have a greater risk of treatment failure.

A case of micronodular pneumocyte hyperplasia diagnosed through lung biopsy using thoracoscopy.

We present a case of a 39-year-old woman with sporadic tuberous sclerosis (TSC), whose chest radiograph demonstrated bilateral diffuse nodular shadowing. A transbronchial lung biopsy specimen revealed the possibility of multiple atypical adenomatous hyperplasia (AAH), which had not been reported in TSC. Thoracoscopic lung biopsy was, therefore, performed. The specimens revealed the characteristic histological and immunohistochemical features of micronodular pneumocyte hyperplasia, which has been reported as an extremely rare pulmonary manifestation of TSC. In addition, no evidence of AAH or any other pulmonary involvements of TSC including lymphangioleiomyomatosis were detected in biopsy specimens obtained at thoracoscopy.

Macroscopic characteristics of pleural metastases arising from the breast and observed by diagnostic thoracoscopy.

A study was carried out on 85 patients suffering from breast cancer with pleural effusion. A thoracoscopy was done on each patient, both to establish the etiology of pleurisy and to perform pleurodesis in those patients whose diagnosis was established by other means. In addition to the gathering of general data on each patient, a description is given of the macroscopic characteristics of the effusions, their cytology, and the forms and locations of the pleural metastases. Differences were encountered in the tendency toward pleural metastases according to the different levels involved and to whether the tumor was homolateral or contralateral. Generally, the former exhibited a preference for the costal pleura, whereas contralateral cancers tend to affect the mediastinal pleura. Other data of interest are likewise briefly described.
