Videothoracoscopic surgery for thoracic neurogenic tumors: a 7-year experience.

While videothoracoscopic surgery has rapidly become accepted as an effective method of performing minimally invasive surgery, the advantages and feasibility of using this surgical technique for the treatment of neurogenic tumors of the thorax are not yet well defined. Between August 1992 and May 1999, 15 solitary thoracic neurogenic tumors were surgically excised using videothoracoscopic surgery in our hospital. The patients comprised six women and nine men, with a mean age of 38.1 years. The mean tumor size was 3.5 cm, with a range of 1.5-6.5 cm and included 12 schwannomas, 2 ganglioneuromas, and 1 neurofibroma. Among the 15 patients, 4 were treated using videothoracoscopic surgery plus minithoracotomy. The only complication associated with videothoracoscopic surgery was hoarseness which developed in one patient. Our experience indicates that videothoracoscopic surgery is a useful alternative to facilitate the excision of small thoracic neurogenic tumors.

Risk and hazards of video-thoracoscopic surgery: a collective review.

Since 1990, video-thoracoscopy has rapidly gained widespread acceptance. In contrast to conventional thoracoscopy no comprehensive studies of potential risks and hazards have been carried out. To date interest has centered on possible indications and thoracoscopic techniques. Based on a review of the literature, this article summarizes and comments on possible complications. In a meta-analysis (Medline, January 1989 until December 1994), all publications dealing with thoracoscopy were collected. Those papers concerned with video-thoracoscopy were further evaluated if the following criterias were fulfilled: first, the endoscopist employed a video-camera connected to the thoracoscope; second, separate entry sites were used for telescope and instruments. Of 345 papers, 145 met the above criterias, 5280 thoracoscopies could be analysed for more than 30 indications. The calculated mortality rate was 0.3% and the complication rate 3.61%. In 55 of all cases (1.04%), the intervention had to be converted to open surgery. Video-thoracoscopic thoracic surgery has gained acceptances as a complement to open thoracic surgery. It may now be regarded as a safe technique. Nevertheless, serious complications such as implantation metastasis of the thoracic wall after thoracoscopy or injury to the recurrent nerve demonstrate the complexity of thoracoscopic surgery. Practitioners should therefore be proficient in thoracic surgery. The importance of meticulous technique and rigid adherance to safety guidelines even in diagnostic procedures, must be stressed.

Videothoracoscopic excision of thoracic neurogenic tumors

Videothoracoscopic surgery is a new procedure for treating neurogenic tumors of the thorax. Feasibility and utility of this technique are not yet well defined. Over a 26-month period, 26 neurogenic tumors of the thorax were treated in five general thoracic surgery centers performing videothoracoscopic surgery. Indications and contraindications for this new procedure and initial results were retrospectively studied. Contraindications to videothoracoscopy included intraspinal extension of the tumor (n = 3), spinal artery involvement (n = 2), tumors more than 6 cm in diameter borderline located within the thorax (n = 2), and middle mediastinal location (n = 1). Videothoracoscopy was performed in 18 patients. Conversion to thoracotomy was required in 3. In 1 patients, subsequent chest wall resection was performed because of malignancy. Postoperative hospital stay was uneventful. It was shorter after videothoracoscopy. Postsurgical pain was more acute in patients who had thoracotomy or conversion to thoracotomy. Videothorascopy is a good alternative for managing neurogenic tumors of the thorax when deemed feasible. There is a tendency toward a shorter hospital stay with less pain in patients treated by this new procedure.

Technical report: Videothoracoscopic resection of a peripheral pulmonary lesion

SummaryWe report a patient with a peripheral pulmonary ‘tumour’ in the left anterior basal segment who was successfully treated using thoracoscopic techniques. The clinical indication for contemplating use of videothoracoscopic surgery was a negative histopathology in transthoracic needle biopsy. An ENDO-GI A-Stapler was used for transresection and closure of the lung tissue. The post-operative pain and the length of hospital stay were markedly reduced compared to open thoracotomy procedures.

Surgical endoscopy in thoracic surgery

From November 1990 to April 1992, 32 patients were operated on by video thoracoscopic surgery (VTS). Included were 22 males and 10 females, mean age 47.6 years. VTS has been used therapeutically on 25 occasions: 20 spontaneous pneumothoraxes; two recurrent pleuritis; two cysts; one mediastinal; one pulmonary; and one thoracic sympathectomy. VTS was also used diagnostically seven times: five lung biopsies and two mediastinal lymph node biopsies. It was necessary to perform a mini-thoracotomy in one patient and proceed to immediate thoracotomy in three patients. There were no deaths in this series, the morbidity was two patients with collapsed iungs, one of which required drainage. VTS must be performed under standard thoracic surgical conditions: selective intubation, and fully equipped to make an immediate thoracotomy. The advantages of VTS are aesthetic and functional, the post-operative pain is reduced in intensity and duration. At present, VTS is indicated for the treatment of spontaneous pneumothorax, the assessment and biopsy of mediastinal lymph node and the excision of some lung lesions. Improvements in the apparatus should lead to a broadening of these indications in the future. surgical endoscopy / thoracic surgery.
