[Medical and surgical management of noniatrogenic traumatic tracheobronchial injuries]. / Manejo médico-quirúrgico de las lesiones traqueobronquiales traumáticas no iatrogénicas.

OBJECTIVE: To describe the medical and surgical management of noniatrogenic traumatic tracheobronchial injuries. PATIENTS AND METHOD: From January 1993 to July 2004, 15 cases of traumatic tracheobronchial injury were treated in our department. The diagnosis was established by bronchoscopy and a computed tomography chest scan was performed on all patients. Surgical treatment was selected for patients with unstable vital signs, an open tracheal wound, associated esophageal lesions, progression of subcutaneous or mediastinal emphysema, mediastinitis or suspicious mediastinal secretions on imaging tests, or difficulties with mechanical ventilation due to the traumatic tracheobronchial injury. RESULTS: The mean (SD) age of the patients was 35.5 (18.9) years and 12 (80%) were male. Of the 15 cases, 13 (86.7%) had penetrating trauma and 2 (13.3%) blunt trauma. The most common location of the injury was in the bronchi (9 cases; 60%), followed by the cervical trachea (4 cases; 26.6%), followed by both the thoracic trachea and bronchi (2 cases; 13.4%). The most common initial symptom was subcutaneous emphysema, which presented in 11 (73.3%) patients. Chest (12 cases; 86.7%) and orthopedic injuries (9 cases; 60%) were the most common associated injuries. Surgery was the treatment of choice in 11 (73.3%) cases and conservative medical treatment in 4 (26.7%). An irreversible brain injury caused the death of 1 patient receiving conservative treatment. CONCLUSIONS: Tracheobronchial injuries may be treated conservatively if they meet strict selection criteria. Size and location should not be used as selection criteria for surgical treatment.

[Importance of routine mediastinal staging in women with non-small cell lung cancer]. / Importancia de la estadificación mediastínica, sistemática en mujeres con carcinoma broncogénico, no microcítico.

OBJECTIVE: To study the specific importance of mediastinal staging in women with nonsmall cell lung cancer. PATIENTS AND METHODS: Between July 1981 and September 2003 we surgically staged 2172 patients with nonsmall cell lung cancer who met the inclusion criteria for resectability and operability. A subgroup of 108 women was studied. Cervical mediastinoscopy was performed in all cases, with the addition of anterior mediastinotomy in cases with left upper lobe involvement. All patients underwent a preoperative computed tomography chest scan. RESULTS: Cervical mediastinoscopy was performed on all 108 patients, 26 of whom also underwent anterior mediastinotomy. Positive findings were recorded in 44 (40.7%) of the 108 cases: 39 of the 108 mediastinoscopies (36.1%), 9 of the 26 mediastinotomies (34.6%), and in 5 cases (19.2%) both mediastinoscopy and mediastinotomy. Nodal involvement was found in 13% of cases in clinical stage IA and 30.8% of cases in clinical stage IB. The percentage of positive findings was significantly higher for cases with adenocarcinoma or large cell carcinoma (P<.05). We performed 67 thoracotomies: 46 patients underwent lobectomy (42.6% of the 108), 7 bilobectomy (6.5%), 9 pneumonectomy (8.3%), and 5 exploratory thoracotomy (4.6%). The agreement between clinical staging after mediastinoscopy and pathological staging after thoracotomy was 47% (stage IA) and 57% (stage IB). CONCLUSIONS: Routine mediastinoscopy is indicated for all women with nonsmall cell lung cancer, regardless of clinical stage.

[Octreotide for conservative management of postoperative chylothorax]. / Tratamiento conservador con octreótido del quilotórax posquirúrgico.

Postoperative chylothorax after lung resection is a major problem leading to morbidity and mortality and requiring reoperation in a large number of cases. The most advisable and least aggressive option is conservative management in progressive stages: a diet rich in medium-chain fatty acids and/or total parenteral nutrition, in addition to chest tube drainage. Including octreotide in this regimen seems to be related to a higher success rate without the need for surgery. We report a case in which the effectiveness and safety of octreotide in the resolution of postoperative chylothorax was excellent.
