Wedge resection versus lobectomy for stage I (T1 N0 M0) non-small-cell lung cancer.

Background: The role of nonanatomic wedge resection in the management of stage I (T1 N0 M0) non-small-cell lung cancer continues to be debated against the present gold standard of care--anatomic lobectomy.

Methods: We analyzed the results of 219 consecutive patients with pathologic stage I (T1 N0 M0) non-small-cell lung cancer who underwent open wedge resection (n = 42), video-assisted wedge resection (n = 60), and lobectomy (n = 117) to assess morbidity, recurrence, and survival differences between these approaches.

Results: There were no differences among the three groups with regard to histologic tumor type.

Acute and chronic morbidity differences between muscle-sparing and standard lateral thoracotomies.

Introduction: Opinions differ regarding differences between totally muscle-sparing thoracotomy and standard lateral thoracotomy approaches to pulmonary resection with respect to operative time, postoperative pain and morbidity, and occurrence of chronic postthoracotomy pain syndromes and subjective shoulder dysfunction.

Methods: Three hundred thirty-five consecutive patients undergoing muscle-sparing thoracotomy (n = 148) or lateral thoracotomy (n = 187) to accomplish lobectomy for stage I lung cancer during a 40-month period were evaluated. Local rib resection was not employed, and two chest tubes were routinely used after operation in both thoracotomy groups.

"Keyhole" coronary artery bypass surgery.

Objective: The objective of this study was to identify the utility of "keyhole" thoracotomy approaches to single vessel coronary artery bypass surgery.

Summary Background Data: Although minimally invasive surgery is efficacious in a wide variety of surgical disciplines, it has been slow to emerge in cardiac surgery. Among 49 selected patients, the authors have used a left anterior keyhole thoracotomy (6 cm in length) combined with complete dissection of the eternal mammary artery (IMA) pedicle under thoracoscopic guidance or directly through the keyhole incision to accomplish IMA coronary artery bypass grafting (CABG) to the left anterior descending (LAD) coronary artery circulation or to the right coronary artery (RCA).

Unilateral thoracoscopic surgical approach for diffuse emphysema.

We evaluated the use of a lateral thoracoscopic approach for lung reduction surgery in patients with diffuse emphysema. Sixty-seven patients with a mean age of 61.9 years underwent operation.

Diagnosing the indeterminate pulmonary nodule: percutaneous biopsy versus thoracoscopy.

Background: The malignant potential of indeterminate solitary pulmonary nodules (SPN) mandates accurate diagnostic management.

Methods: 613 patients undergoing either computed tomographic lung biopsy (CT-Bx) (n = 312) or thoracoscopic excisional biopsy (Thor-Bx) (n = 301) for the diagnosis of SPN were evaluated for relative accuracy, complications, and effect on clinical treatment.

Results: CT-Bx identified a malignant diagnosis (Dx) in 201 (64%) of 312 patients; 85 (42%) underwent operations.
