Chylomediastinum following tracheal surgery.

Chylomediastinum is a rare but serious complication following thoracic procedures. A 70-year-old woman underwent tracheal resection through median sternotomy. Sternal dehiscence and chylous drainage appeared on the second postoperative week. Oral intake was stopped and total parenteral nutrition was started. Drainage stopped after two weeks. The region was ligated with a purse string suture during revision of sternotomy. A minimal lymph leakage was determined on control Tc-99 lymphoscintigraphy, which indicated injury of the thoracic duct. The patient has been problem-free for 9 months.

The coincidence of mediastinal tuberculosis lymphadenitis in lung cancer patients.

Mediastinal lymph node enlargement in operable non-small cell lung cancer is of clinical importance since it indicates the high possibility of nodal metastasis. The coincidence of tuberculosis and lung cancer is detected by the mediastinal lymph node staging of lung cancer patients. In our study, we retrospectively re-evaluated the records of patients who had been hospitalized with the diagnosis of lung cancer for the past 10 years. The mean age was 58 +/- 10 years (ranging from 39 to 72). A tuberculous lymphadenitis was detected in 16 of the 315 (5.1%) patients in one and/or multiple stations by either mediastinoscopy or thoracotomy. Inferior paratracheal lymph nodes (4R-4L) were the most frequently affected. None of the patients had a history of primary tuberculosis infection. The cell type was squamous cell carcinoma in ten patients (62.5%) and adenocarcinoma in six patients (37.5%). The tumour was located in the right lung in nine patients (56.2%). The most frequently involved site was the right upper lobe (n = 13, 81.2%). N2 disease was detected in six patients (37.5%). Our study showed that 5.1% of lung patients had tuberculous lymphadenitis coincidentally. The diagnosis and treatment of this latent disease could be considered as important, especially in lung cancer patients who would potentially receive radiotherapy or chemotherapy which alters the immune system. However, the real value of this finding needs further study.

Thoracic surgical operations performed under local anesthesia and sedation for diagnosis and treatment.

Generally, the operative procedures for the diagnosis or treatment of mediastinal, intrathoracic and/or chest wall lesions requiring rib resection are performed under general anesthesia. Although evidence suggests that thoracoscopy can be performed under local anesthesia, no report has indicated that some major thoracic procedures can be accomplished without general anesthesia. In our study, we advocate that certain surgical procedures could be performed under local anesthesia with a performance similar to that of general anesthesia. Thirty patients underwent thoracic procedures with local anesthesia and sedation for diagnosis and treatment. Seventeen of the patients were men, and the mean age of the patients was 49.6 years (range 16 to 71 years). There were 13 diagnostic procedures, and 17 procedures were for treatment purposes. The operative procedures performed using only local anesthesia were mini-thoracotomy (n = 9), mediastinotomy (n = 4), revision of a full-thickness posterolateral thoracic incision (n = 7), resection of the chondroma (n = 4), Eloesser flap (n = 1), metastasectomy of the chest wall (n = 3), empyectomy (n = 1), and video-assisted thoracoscopy (n = 2). Severity of pain was evaluated by VAS. There were no oral or intravenous analgesic requirements in the early postoperative period. No complications attributable to the procedure were observed. Thoracic surgical procedures for diagnosis and treatment performed under local anesthesia are simple, effective, economical and comfortable for the patient.
