Diagnostic and therapeutic pleuroscopy. Experience with 127 patients.

Experience with 127 pleuroscopies using the mediastinoscope is reviewed. The most frequent indications were pleural effusion (73 patients), pleural involvement by tumor (14), empyema (14), and recurrent pneumothorax (14). Findings were diagnostic in 119 of 127 patients (93.7 percent). Pleural metastases were found in 63 patients, primary pleural or lung tumor in six, nonspecific or tuberculous empyema in 17, emphysematous blebs in 12 and less common findings in the remainder. Pleuroscopy was usefully employed to determine chest wall penetration by a malignant lung tumor in five patients with severely restricted pulmonary reserve. Positive findings helped to avoid unnecessary thoracotomy. There were two minor complications and no deaths. Malignant pleural effusion causing dyspnea was managed successfully by talc insufflation under direct vision in 35 of 39 patients. Talc was also used, with equal success and without complications, in eight patients with recurrent pneumothorax and in two with empyema after evacuation of pus. We conclude that pleuroscopy is a useful diagnostic and therapeutic procedure, simple and well tolerated, with the diagnostic yield of over 90 percent and virtually free of complications. It provides the best way of insufflating talc for pleurodesis.

Bronchial carcinoid tumors: twenty years' experience.

We reviewed 69 patients with documented carcinoid tumors, 67 of whom had resectable disease. Operations included nine pneumonectomies, 31 lobectomies, 12 bilobectomies, five segmental resections, and 10 sleeve resections. Follow-up on 65 patients reveals 40 surviving beyond 5 years and 13 beyond 20 years since resection. There were no operative deaths and only one recurrence (local) that was subsequently successfully resected. Twenty patients had had recurrent unifocal pneumonitis or hemoptysis for up to 5 years prior to diagnosis. Two patients had the carcinoid syndrome. Biopsy was performed on 23 tumors and resulted in "moderate-to-severe" hemorrhage in six cases. Lymphatic spread was present in seven cases. All seven are alive and free of disease, six of whom have been followed from 5 to 24 years. Diseased resection margins were present in two cases, with both surviving 20 years after resection. All 10 sleeve resections were performed more than 5 years ago. We conclude that carcinoid tumors carry a favorable prognosis upon resection, even when intrathoracic lymphatic metastases are present and are resected. Lung-sparing resections including sleeve resections should be utilized. Recurrent pneumonia or hemoptysis or both requires diligent investigation. Biopsy of the tumors may be performed with care.

Treatment of varicose veins by compression sclerotherapy.

Treatment by compression sclerotherapy was carried out in 80 legs with symptomatic varicose veins. Excellent results were achieved initially in 60 legs, and there was improvement after retreatment of an additional six, for a total of 66 legs. In the remaining 14 legs, there was partial, but considerable, improvement. There were no major complications. Treatment of varicose veins does not necessarily have to be operative. Compression sclerotherapy should be recognized more widely as an acceptable primary treatment aimed at improving local hemodynamics rather than stripping of a vein with good potential for recovery. With the appropriate, not haphazard, use of sclerosing solutions combined with prolonged compression, excellent results usually can be achieved.

Inflammatory fibrous histiocytoma of the bronchus.

A 33 year-old woman underwent lobectomy of the middle and lower lobes of the right lung because of inflammatory fibrous histiocytoma of the bronchus. To our knowledge, this is the first description of such a tumor originating in the bronchus.

Primary carcinoma of the appendix.

Primary adenocarcinoma of the appendix is a rare tumor. Fewer than 200 cases are on record. Correct preoperative diagnosis is virtually nonexistent. Two patients with adenocarcinoma of the appendix are described. Although appendectomy appears to be adequate treatment for carcinoid, right hemicolectomy is, in our opinion, the treatment of choice for mucinous cystadenocarcinoma, while it is mandatory in cases of adenocarcinoma of the colonic type.

Thymolipoma simulating cardiomegaly: a clinicopathological rarity.

This report describes a 19-year-old girl with a chest radiograph strongly suggestive of cardiomegaly. Although she did not consent to haemodynamic studies, cardiomegaly wasru led out on the basis of the clinical course. Careful radiological study proved the existence of a large mass in the anterior mediastinum, simulating cardiomegaly. At thoracotomy a thymolipoma weighing 450 g was resected. The pathogenesis of thymolipoma is discussed.
