Thoracoscopy in the management of posttraumatic persistent pneumothorax.

BACKGROUND: Persistent posttraumatic pneumothorax (PPP) is an uncommon complication of traumatic injuries of the chest, usually managed with suction drainage and involving prolonged hospital stays. This study was conducted to assess the advantages of using video-assisted thoracoscopic surgery (VATS) in the management of patients with PPP. STUDY DESIGN: Eleven patients with PPP underwent VATS for diagnosis and for definitive treatment. RESULTS: Before VATS was done, all patients had undergone multiple attempts to resolve the PPP; the hospital stay before VATS was 10 days (range, 4-14 days). In 10 patients, the cause of the PPP was identified and a segmental stapled resection was performed, with complete success in resolving the air leak and obtaining pleural synthesis. In another patient, the source of the air leak was not identified and a thoracoscopically assisted chemical pleurodesis was performed, with immediate cessation of the air leak. All chest tubes were removed within 48 hours of the procedure; 9 patients were discharged within 72 hours of VATS. Preoperative computed tomography of the chest was useful in 2 patients, but bronchoscopy did not disclose any major airway injury. CONCLUSIONS: Videothoracoscopy is an accurate, safe, and reliable alternative to an open thoracotomy in the management of patients with PPP. In the patients in whom the procedure was completed, excellent results were obtained and the hospital stay was reduced. We believe that VATS should be used earlier and more frequently after failure of conservative management in such patients.

Fiber-endoscopic thoracoscopy for diaphragmatic injury in children.

Diagnosis of a diaphragmatic injury is important to prevent late sequelae of herniation of abdominal viscera and intestinal gangrene. A safe, simple, reliable and inexpensive method of assessing the diaphragm was devised for use in the emergency department. A standard fiberoptic upper gastrointestinal endoscope was used as a thoracoscope to visualize the diaphragm, using the thoracostomy tube incision as the portal of entry to the thoracic cavity. Two cases in which this technique was used are presented. The procedure was well tolerated and allowed for an adequate view of the diaphragm and prompt decision making.

The role of emergency thoracoscopy in the management of congenital cystic adenomatoid malformation of the lung associated with oesophageal atresia.

Congenital cystic adenomatoid malformation of the lung associated with oesophageal atresia is exceptional. The authors describe a case of a mixed type I - II congenital cystic adenomatoid malformation of the left lung associated with oesophageal atresia and tracheooesophageal fistula in a male infant. The interesting aspect of this case is not only the extremely rare association - only two reports in the literature - but the surgical choices. In fact, two weeks after surgical repair of the oesophageal atresia, the growth of the cystic volume of the congenital adenomatoid malformation made respiratory weaning very difficult, and it was therefore decided to solve the respiratory distress by opening the tensional cysts using a thoracoscopic access. The advantage of this treatment was that it decompressed the underlying healthy lung tissue and permitted the expansion of the normal lobar parenchyma. This is a palliative approach that allows the mandatory definitive resection of the affected lung lobe to be postponed until a later time.

Video-assisted thoracoscopy in single-stage resection of a para-aortic posterior mediastinal dumbbell tumor.

We report the successful single-stage thoracoscopic resection of a neurogenic mediastinal dumbbell tumor close to the aortic arch, using a combined posterior approach. A 63-year-old asymptomatic male was referred to our hospital for evaluation of an abnormal round shadow in the left thoracic cavity on a chest radiograph. He was diagnosed to have an intrathoracic and intraspinal neurogenic dumbbell-shaped tumor close to the aortic arch. Surgery combined both a laminectomy and thoracoscopic tumor resection. The tumor was lysed as deeply as possible via a posterior approach, then with the patient in the right lateral position the pleura around the tumor on the aortic side was clipped and cauterized thorocoscopically, freeing the tumor completely and allowing it to be extracted in toto.

The surgical treatment of spontaneous pneumothorax by video-thoracoscopy.

Since March 1991, 66 patients with spontaneous pneumothorax were treated thoracoscopically employing the principles of minimally invasive surgery. Of these cases, 14 involved a first occurrence, 18 had a pneumothorax longer than 7 days, and 34 were recurrences; causative lung disease was determined in 25 patients. The blebs and bullae were ligated with chromic catgut Roeder loop or resected with the Endo-GIA stapler. If pathological changes to the lung consistent with Vanderschueren's stage IV were found (n = 36), the treatment was extended to include a parietal pleurectomy. No complications requiring therapy were encountered, the average postoperative hospital stay was 3.2 days. During an average observation period of 10 months (1-27) the recurrence rate was 4.5%. Thoracoscopic therapy proved to be a simple and safe method for all forms of spontaneous pneumothorax.

Lymphatic drainage of carbon particles injected into the pleural cavity of the monkey, as studied by video-assisted thoracoscopy and electron microscopy.

OBJECTIVES: The aim of this study was to clarify the dynamics of lymphatic drainage of the pleural cavity to understand the mechanism of malignant pleural effusion. METHODS: We injected carbon particles into the pleural cavity of monkeys subjected to general anesthesia. We then observed the parietal pleura with a video-assisted thoracoscope and scanning and transmission electron microscopes to examine the regions of the parietal pleura where the carbon particles had been absorbed. RESULTS: The video-assisted thoracoscope showed that the carbon particles had gone directly to the costal, mediastinal, and diaphragmatic pleura by 10 to 15 minutes after injection. From the scanning and transmission electron microscopes, we found that the parietal pleura in the costal and mediastinal regions consisted of 3 elements: a layer of small mesothelial cells, the macula cribriformis, and lymphatic lacunae. Stomata (3-5 microm in diameter) were found between the small mesothelial cells. The macula cribriformis was composed of densely packed collagen fibrils and had many foramina (3-10 microm in diameter). Intrapleurally injected carbon particles were carried into the lymphatic lacunae via the stomata and vesicles of the mesothelial cells and the foramina of the macula cribriformis. The lymphatic lacunae filled with carbon particles were richly distributed in both the anterior costal pleura and the mediastinal pleura. CONCLUSION: We suggest that the mesothelial stomata and the macula cribriformis are structures essential to the absorption of macromolecules and cellular elements from the pleural cavity into the lymphatic system.

Thoracoscopy: the preferred approach for the resection of selected posterior mediastinal tumors.

The posterior mediastinum is a common site for neurogenic tumors. These are mostly asymptomatic and detected incidentally during radiologic investigations. However, they occasionally present with compressive or neurologic symptoms. The tumors are mostly benign but can also be malignant. Left untreated, they continue to grow. Therefore, once detected, resection is always advised. Traditionally, resection has been performed by standard posterolateral thoracotomy. More recently, such tumors have been removed thoracoscopically. We report our experience with three such cases and present a comprehensive analysis of cases of thoracoscopic resection of posterior mediastinal neurogenic tumors reported in the English literature to suggest guidelines for their current management.

Hans Christian Jacobaeus: Inventor of human laparoscopy and thoracoscopy.

Hans Christian Jacobaeus performed the first clinical laparoscopic surgery in Stockholm. This pioneering procedure was based on the animal experiments of Georg Kelling (1866-1945), a German physician from Dresden, who performed the first laparoscopic intervention in 1901 using a Nitz cystoscope in a dog. In 1910, Jacobaeus published his initial experiences with laparoscopic surgery in the Münchner Medizinischen Wochenschrift under the title "The Possibilities for Performing Cystoscopy in Examinations of Serous Cavities." He used this technique for diagnostic purposes in undefined abdominal complaints and functional impairment. Jacobaeus was the first who pointed out the possibility of injuring organs, especially the intestines, by inserting the trocar. In 1910, Jacobaeus recognized the immense diagnostic and therapeutic possibilities of laparoscopic surgery, as well as its difficulties and limits. He also was the first to realize the need for initial endoscopic training in animals and corpses. He promoted the development of special laparoscopic instruments to optimize and simplify the procedure.
