Background: The efficacy of video-assisted thoracoscopic surgery lobectomy in patients with previous coronary artery bypass grafting (CABG) surgery is controversial.

Objectives: To investigate whether skeletonized left internal mammary artery (LIMA) mobilization contributes to the development of severe adhesions, which will affect what type of lung surgery (open or closed procedure) will be required in the future.

Methods: Eight patients (mean age 73.9 years) with previous CABG surgery using a LIMA to left anterior descending (LAD) graft underwent left-sided lobectomy for operable non-small cell lung carcinoma. 

Results: The lobectomy by thoracotomy rate was 62.5% (5 patients), generally in patients with tumors in the left upper lobe or in patients post-neoadjuvant chemotherapy, while the video-assisted thoracic surgery lobectomy rate was 37.5% (3 patients). Mean hospital stay was 8.3 days. There was no mortality or major morbidity, apart from six minor complications in four patients (50%) (air leak, atrial fibrillation, atelectasis, pneumonia). 

Conclusions: Patients with operable non-small cell lung carcinoma following CABG surgery who need left upper lobe resection do not benefit from the video-assisted thoracoscopic surgery technique due to significant adhesions between the LIMA to LAD graft and the lung. The method of preserving a small portion of the lung on the LIMA to LAD graft may help during left upper lobe resections. Adhesions in the left pleural space after LIMA mobilization appear to generally minimally affect left lower lobe video-assisted thoracoscopic surgery.

 

Background: Multidrug-resistant tuberculosis (MDR-TB) presents a difficult therapeutic problem due to the failure of medical treatment. Pulmonary resection is an important adjunctive therapy for selected patients with MDR-TB.

Objectives: To assess the efficacy of pulmonary resection in the management of MDR-TB patients.

Methods: We retrospectively reviewed the charts of MDR-TB patients referred for major pulmonary resections to the departments of thoracic surgery at Assaf Harofeh and Wolfson Medical Centers. For the period under study, 13 years (from 1998 to 2011), we analyzed patients’ medical history, bacteriological, medical and surgical data, morbidity, mortality, and short-term and long-term outcome.

Results: We identified 19 pulmonary resections (8 pneumonectomies, 4 lobectomies, 1 segmentectomy, 6 wedge resections) from among 17 patients, mostly men, with a mean age of 32.9 years (range 18–61 years). Postoperative complications developed in six patients (35.3%) (broncho-pleural fistula in one, empyema in two, prolonged air leak in two, and acute renal failure in one). Only one patient (5.8%) died during the early postoperative period, three (17.6%) in the late postoperative period, and one within 2 years after the resection. Of 12 survivors, 9 were cured, 2 are still under medical treatment, and 1 is lost from follow-up because of poor compliance.

Conclusions: Pulmonary resection for MDR-TB patients is an effective adjunctive treatment with acceptable morbidity and mortality.
 

Background: Fractures of the stemum may be associated with major injuries to thoracic organs, with serious consequences.

Objective: To assess the hospital course of patients diagnosed with isolated sternal fracture.

Methods: We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the period from January 1990 through August 1999.

Results: Fifty-one patients were involved in motor vehicle accidents, and the remainder sustained the injury as a result of a fall. Lateral chest X-ray upon admission was diagnostic in the majority of these patients (n=53). Electrocardiography (n=52) was abnormal in four patients – old myocardial infarction (n=1), non-specific ST-T changes (n=3). Cardiac enzymes (creatine-kinase-MB, n=42) were pathologically elevated in five patients. Echocardiography, performed in patients with ECG[1] abnormalities and/or elevated myocardial enzymes (n=7), was normal in these patients as well as in another 18 patients. There were no intensive care unit admissions or arrhythmias during the hospital stay, which ranged from 6 hours to 6 days (mean 2.3 ± 1.3 days, median 2 days).

Conclusion: Our findings support the view that patients with isolated sternal fracture, who have no abnormality in ECG and cardiac enzymes during the early hours after injury, are expected to have a benign course and can be discharged home from the emergency room within the first 24 hours.
