Place of video-thoracoscopy in thoracic surgical practice.

The advent of video-endoscopy revolutionizes the practice of surgery. Within a short span of time, video-assisted thoracic surgery (VATS) has become an acceptable approach to a wide range of thoracic procedures. The use of VATS as a diagnostic modality is now well established. For therapeutic procedures, VATS has also been generally accepted for the treatment of such conditions as primary spontaneous pneumothorax, loculated effusions, thoracodorsal sympathectomy, and resection of simple mediastinal cysts. Its roles in more complex procedures such as thymectomy and anatemic lung resections, however, remain poorly defined at present, even though the existing intermediate-term results are encouraging. VATS is still in evolution. Miniaturization of instruments promises to reduce access-induced trauma even further. On the other hand, attention to cost-containment is essential if VATS is to be applicable to patients in developing countries. Technology will continue to change. Carefully conducted clinical trials should precede the general acceptance of any new technology, no matter how attractive it may appear initially.

Facilitation of alternative one-lung and two-lung ventilation by use of an endotracheal tube exchanger for pediatric empyema during video-assisted thoracoscopy.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has emerged as an innovative and popular procedure for the management of postpneumonic empyema in children refractory to medical response. Alternative uses of two- and one-lung ventilations have been required during VATS. This study evaluated the efficacy of alternating one- and two-lung ventilation through intraoperatively through the same single-lumen endobronchial tube using a tube exchanger during a thoracoscopic procedure for pediatric empyema. METHODS: Between May 1995 and August 2001, 62 consecutive pediatric patients undergoing VATS for evacuation of the loculated empyema cavity were studied. The same single-lumen endobronchial tube was used, with an indwelling endotracheal tube exchanger in place for readjustment of the tube position to provide alternation of one- and two-lung ventilations in a thoracosopic procedure. Duration of operation, heart rate, mean arterial pressure, peak airway pressure, an partial pressure of oxygen (PaO(2)) and carbon dioxide (PaCO(2)) changes during one- and two-lung ventilations were recorded. The quality of lung deflation and inflation was rated by the surgeon using direct visualization as excellent, fair or poor. RESULTS: The mean operating time was 90 min (range, 50-120 min). No differences were found in heart rate, mean arterial pressure, or PaO(2) during one- and two-lung ventilations. Peak airway pressure and PaCO(2) during two-lung ventilation were significantly higher than during one-lung ventilation. The quality of lung deflation and inflation was judged excellent for all the patients. CONCLUSIONS: The VATS procedure can be performed safely and effectively in children using proper anesthetic technique. Retention of a tube exchanger within a single-lumen endobronchial tube an easily provide alternative one- and two-lung ventilations without inducing any significant airway flow obstruction during the operation.

Comparative retrospective study of surgical treatment of spontaneous pneumothorax. Thoracotomy vs thoracoscopy.

BACKGROUND: Since May 1992 we have used video-assisted thoracic surgery (VATS) for the treatment of the spontaneous pneumothorax. In this study we review the results obtained with this technique and we compare them with those obtained by conventional surgery (1976-1992). METHODS: 110 patients (98 males and 12 females, age 15-83 years) were operated by VATS, and 627 patients (567 males and 60 females, age 14-89 years) by conventional surgery. The surgical technique and the complications are compared. No one died. RESULTS: Although the number of complications was greater in the first group than in the second one (29.5% vs 15.1%), this is attributed to the lack of experience among surgeons in the first cases; which complications nearly disappeared in the last 60 patients. Less pain, better recovery, and shorter hospital stay resulted. CONCLUSIONS: For us VATS is the ideal technique with which to treat spontaneous pneumothorax.

The use of multiplane transesophageal echocardiography to evaluate residual patent ductus arteriosus during video-assisted thoracoscopy in adults.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has emerged as an innovative and popular procedure for interruption of patent ductus arteriosus (PDA), while intraoperative transesophageal echocardiography (TEE) has proven to be an effective monitor in the evaluation of residual patency. Previous reports on the adequacy of surgical interruption of PDA under VATS and TEE are available for pediatric patients, but only limited information is available for adults with PDA. MATEIALS AND METHODS: Between August 1995 and October 1997, we monitored 35 adult patients undergoing PDA interruption via VATS with Hewlett-Packard color Doppler multiplane TEE throughout the procedure. The average PDA diameter was 10.2 +/- 1.8 mm. All the PDA were completely ligated. RESULTS: Thirty-two patients showed no ductal flow after double ligation. In the other three patients, residual flow was detected intraoperatively after double ligation, but it was quickly abolished by the third ligation. One patient showed faint ductal flow by transthoracic echocardiography at postoperative follow-up, but no reintervention was needed. CONCLUSIONS: Our study showed that, with the refinement of adult PDA interruption via VATS, intraoperative multiplane TEE provides higher resolution for direct evaluation of the entire course of PDA ligation without interrupting the surgical procedure and minimizes the incidence of complications.

ICD implantation via thoracoscopy, "mailslot" thoracotomy, and subxiphoid incision.

An improved method of thoracoscopic implantable cardioverter defibrillators implantation is described. "Mailslot" thoracotomy is more expeditious than thoracoscopic implantation via multiple ports. If required for adequate defibrillation thresholds, subxiphoid, subdiaphragmatic implantation of a defibrillator patch may be performed.

Invasive staging of lung cancer by mediastinoscopy and video-assisted thoracoscopy.

Accurate evaluation of the outcomes of clinical trials using preoperative chemotherapy in a multimodality treatment protocol may require invasive pretreatment staging for pathologic confirmation of the clinical TNM. Mediastinoscopy and videothoracoscopy complement each other to provide appropriate staging of lung cancer. Invasive staging utilizing both methods may accurately determine the presence or absence of N2 and N3 disease, and identify T3 or T4 or thoracic M1 disease.

[Usefulness of video-assisted thoracoscopy for the diagnosis of solitary pulmonary nodules].

OBJECTIVES: Various approaches are used for the diagnosis and treatment of solitary pulmonary nodules (SPN) of unknown origin. New imaging techniques and nuclear medicine have provided more information about SPN, but surgical removal is still the most sensitive and specific way to obtain a correct analysis of the lesion. With video-assisted thoracic surgery (VATS), a histological diagnosis can be obtained without resorting to thoracotomy. In the present study we describe our experience with the diagnosis and treatment of SPN using VATS. MATERIAL AND METHODS: From July 1992 through April 2001, 182 patients were operated on for SPN in our department. DESIGN: Retrospective study. Mean age: 59.2 years (12-78). Sex: 39 women and 143 men. Localization: Visual or instrumental exploration in 102 patients, with palpation in 52 cases and using a hookwire guided by preoperative computed tomography in 25 (with failure in 4 of those cases). Tissue was biopsied during surgery and when the lesion was malignant, oncological excision was performed during the same operation. RESULTS: A firm diagnosis was obtained by VATS for 178 patients (98.3%). For three other patients the surgeon had to take a needle biopsy (Tru-cut) during surgery, and in one case conversion to open surgery was necessary. Histopathology: hamartoma: 11; fibrous nodule: 10; bronchiolitis obliterans: 1; pneumoconiosis: 1; mesenchymal tumor: 3; inflammatory pseudotumor: 14; mucormycosis: 1; tuberculoma:17; lymphoma: 1; carcinoid tumor: 6; metastasis: 22; bronchogenic carcinoma: 95. Mortality was 0.55%, with 1 patient dying from massive pulmonary thromboembolism. Morbidity was 5%, from 9 minor complications. CONCLUSIONS: VATS is an effective approach, with low morbidity and mortality. We consider it to be the technique of choice for the diagnosis of all SPN and for the treatment of some, such as benign nodules and solitary metastases.

[Our experience in the treatment of hyperhidrosis of the upper limbs by video-assisted thoracoscopy: an analysis of our first 100 procedures].

Sympathectomy of the thoracic chain is an effective surgical procedure for treating axillary and palmar hyperhidrosis. The procedure has been performed with minimal invasion and good results in recent years through the use of videothoracoscopic surgery. This paper describes the technique and our experience with a series of 50 patients between 16 and 48 years old. The earliest approach was unilateral in successive operations. The procedure was later performed bilaterally, at first with the patients in sequential lateral decubitus positions and later in semi-seated position. Complications were 1 case of incomplete Claude-Bernard-Horner syndrome that resolved spontaneously two months after surgery; 1 failure when sympathectomy was performed without location of the chain, obliging rapid re-operation; laminar pneumothorax in 12% of the series; compensatory hyperhidrosis in 26%; 10% with chest pain due to intercostal involvement, resolving with time; and slight bleeding in 8%. Outcome was excellent, with complete disappearance of axillary and palmar perspiration. Patient satisfaction was 9.2/10 one year after surgery. Mean hospital stay was less than 36 h.
