Bilateral video-assisted thoracoscopic surgery in the supine position for primary spontaneous pneumothorax.

On the basis of the bilateral nature of bullous lesions of the lung, the authors have performed single-stage bilateral video-assisted thoracoscopic surgery (VATS) in the supine position for primary spontaneous pneumothorax in five patients since October 1999. All five patients were males with a mean age of 23 years (range 19 to 29 years). The presenting pneumothorax was ipsilateral (right-sided) in four patients and simultaneous bilateral in the one remaining patient. Apart from the one case of simultaneous bilateral spontaneous pneumothorax (SBSP), all patients had a history of at least one pneumothorax episode requiring tube thoracotomy. Bilateral bullae were confirmed in all patients on preoperative chest computed tomography (CT). Bilateral bullectomy was performed by endo-stapler with no difficulties. Mean operating time was 111 minutes (range 85 to 140 minutes). All patients were returned to the surgical ward in good condition from the operating room immediately after extubation. No complications were observed, and duration of postoperative hospital stay was two to four days. All patients were alive without recurrence of pneumothorax after a mean follow-up period of 25 months (range, 9 to 43 months). Single-stage bilateral VATS in the supine position has shown itself to be an excellent approach for the treatment of bilateral bullous lesions, combining both efficacy and low morbidity.

The figure-L unilateral mini-sternotomy for anterior mediastinal tumor.

We performed a figure-L unilateral mini-sternotomy for anterior mediastinal tumor resection in ten patients. Pathological diagnosis among the ten included six thymomas, three mature teratomas including one with a seminoma component, and one thymic cyst. Mean tumor length was 7 x 5 x 4 cm. The required skin incision was 8 cm in mean length. The third intercostal space was transected in six cases, the fourth intercostal space in four cases. Bilateral internal thoracic arteries were preserved in all cases. All tumors were completely resected without complications during the procedure. Mean operating time was 106 minutes (range 85 to 120 minutes). Postoperative hospital stay ranged from three to seven days without any complications. All patients were alive at the end of a mean follow-up period of 39 months (range 3 to 60 months). The figure-L unilateral mini-sternotomy is considered an effective and useful minimally invasive approach for anterior mediastinal tumors.

Supraclavicular approach without thoracotomy for posterior mediastinal tumor.

Using a right-sided supraclavicular approach, we operated on a 15-year-old girl with a posterior mediastinal neurogenic tumor and von Recklinghausen's disease. The encapsulated 95 x 65 x 40 mm neurofibroma was removed safely and completely without thoracotomy. No peripheral neurologic defect such as Horner's syndrome, paralysis of accessory nerve, or palsy of the right upper extremity was observed after operation. The postoperative course was uneventful and the patient was discharged on the third postoperative day with no symptoms. Today, various adaptations of video-assisted thoracic surgery are frequently utilized for many lesions. However, more direct, safer, and less invasive approaches should be selected based on local anatomy, such as the supraclavicular approach without thoracotomy that we utilized.

A single-stage video-assisted thoracoscopic surgery procedure for simultaneous bilateral spontaneous pneumothorax in a supine position.

We report on the case of a 23-year-old man with simultaneous bilateral spontaneous pneumothorax (SBSP), treated with bilateral video-assisted thoracoscopic surgery (VATS) in a supine position. SBSP is a very rare condition that can be life-threatening when therapeutic techniques fail. We performed a unique operative procedure for SBSP using one-stage bilateral VATS in a supine position. This procedure is less invasive, more effective, and safer for the treatment of SBSP.

Placement of the Dumon stent using a flexible bronchofiberscope via tracheostomy.

In this paper, we report on a new technique of Dumon stent placement using a flexible bronchofiberscope. This procedure was used to insert Dumon stents in two bronchial obstruction and two bronchofistula cases. The stenting technique described here can be used through either a tracheostoma or the oral cavity; it presents a very straightforward and safe procedure that does not require the use of a rigid bronchoscope.

A new combined surgical procedure for severe descending necrotizing mediastinitis with bilateral empyema.

In this report, we will describe the treatment of a 38-year-old man with severe descending necrotizing mediastinitis (DNM) with bilateral empyema. DNM is a rare disease with a high mortality rate, and when accompanied by bilateral empyema, this is particularly serious and potentially fatal. To improve the prognosis of such patients, the establishment of an adequate surgical procedure for satisfactory debridement and drainage is essential. This is the first report on a new combined surgical procedure consisting of right standard posterolateral thoracotomy and left video-assisted thoracoscopic surgery (VATS) for severe DNM with bilateral empyema.

Primary chylopericardium treated with video-assisted thoracoscopic surgery.

Here, we report on a 30-year-old female with primary chylopericardium who successfully underwent thoracic duct clipping and partial pericardiectomy using video-assisted thoracoscopic surgery (VATS). Recently, a few cases of this disease have been treated utilizing VATS. This is a fully detailed description of the treatment of primary chylopericardium including a description of intraoperative findings and photographs obtained during the course of VATS.

[Combined surgery for cardiovascular disease and general thoracic lesions].

Surgical management of patients with concomitant critical cardiovascular disease and resectable general thoracic lesions is controversial. During a 16-year period (1985 to 2001), 15 patients underwent combined cardiovascular and general thoracic operations, of the 2,459 patients who underwent a cardiovascular operation requiring cardiopulmonary bypass at our institution. Patients had cardiovascular symptoms only and the general thoracic lesions were incidentally found by preoperative chest roentgenograms and/or computed tomography. Because of the cardiovascular disease, a pathological diagnosis was precluded before surgery. All except one descending thoracic aortic operation underwent concurrent pulmonary resection after neutralization of protamine following cardiovascular surgery requiring extracorporeal circulation. Lung pathology consisted of pulmonary bullae (n = 7), primary lung cancer (n = 4), benign lung tumor (n = 2), metastatic lung cancer (n = 1), and thymic cyst (n = 1). The pulmonary operations include bullectomy (n = 7), wedge resection (n = 6), lobectomy (n = 3), and removal of a thymic cyst (n = 1) including 2 staged procedures. The final diagnoses in 4 lung cancer cases were T1. N0M0, stage IA (n = 3) and T2N2M0, stage IIIA (n = 1). All malignancies including metastatic lung cancer, were able to be completely resected. The mean intraoperative bleeding volume for the cases was 997 +/- 221 ml, while mean duration of surgery was 382 +/- 31 minutes. Except for 2 cases required long term ventilatory support, the mean durations of tracheal intubation and ICU stay were 2.2 +/- 0.2 and 3.8 +/- 1.0 days respectively. Except for 1 surgical death, mean survival duration and 5-year survival rate were 59.7 +/- 12.5 (5-177) months and 66.3% respectively. These findings suggest that combined pulmonary resection with cardiovascular surgery is safe and offers a favorable prognosis to a selected group of patients.

[Long-term results of aortic arch replacement using combination of deep hypothermic circulatory arrest and retrograde cerebral perfusion; comparison of result for atherosclerotic aneurysm and aortic dissection].

Between 1992 and 2001, 73 patients with aortic arch lesion underwent surgical treatment. The aneurysm was characterized by atherosclerosis in 54 patients (TAA) and by aortic dissection in 19 patients (DAA). All patients received graft replacement under combination of deep hypothermic circulatory arrest and retrograde cerebral perfusion. The hospital mortality rate for all patients was 15.6%. The follow-up period of 61 survival patients ranged from 2 to 90 months (mean 33.2 months). The actuarial survival rate was 93.2%, 83.5%, and 79.7% at 1, 3, and 5 years, respectively. No significant difference was noted between TAA and DAA in the actuarial survival rate. The freedom from vascular complication was 97.9%, 95.8%, and 95.8% at 1, 3, and 5 years, respectively. The rate was significant higher in the patients of DAA than in those of TAA (TAA: 100%, 100%, and 100%, DAA: 90.9%, 81.8%, and 81.8%). The freedom from cardiac complication was 96.4%, 89.7%, and 84.1% at 1, 3, and 5 years, respectively. There was no significant difference between TAA and DAA. The freedom from cerebrovascular complication was 100%, 97.6%, and 83.4% at 1, 3, and 5 years, respectively. No significant difference was noted between TAA and DAA. The late result of surgical treatment for the aortic arch using combination of deep hypothermic circulatory arrest and retrograde cerebral perfusion was satisfied. The long-term survival rate was higher in TAA patient than in DAA one. The possibility remained that fatal vascular complication affected the long-term survival rate.

[Abdominal aortic aneurysm and annuloaortic ectasia in siblings with Marfan syndrome].

A combination of annuloaortic ectasia (AAE) and abdominal aortic aneurysm (AAA) appeared in siblings with Marfan syndrome is presented. The patients were a 53-year-old female and her younger brother. The brother died of arrhythmia twenty years before while waiting for surgical repair of AAE. His AAA and Marfan syndrome were ascertained at autopsy. The female patient received surgical repair for AAA and AAE subsequently. Pathologic study of the resected aneurysm revealed cystic medial necrosis. A combination of AAE and AAA developed in two members of a family with Marfan syndrome is extremely rare.

[Subacute effusive-constrictive pericarditis accompanied with miliary tuberculosis: a case report].

With the advent and the introduction of effective antimicrobial therapy, the mortality for tuberculosis pericarditis decreased in number dramatically. The problems, however, remains in several severe cases. We have experienced a rare case of 74 year old male with subacute effusive-constrictive pericarditis accompanied with miliary tuberculosis. The patient revealed improvement immediately after early an emergent pericardiectomy. However cardiac failure recurred thereafter because of fibrous epicarditis of tuberculous inflammation. Management of subacute effusive-constrictive pericarditis as this has many problems including surgical intervention such as operative timing and indication and/or role of corticosteroids together with antituberculotic drugs.
