Extracorporeal membrane oxygenation after lung transplantation: evolving technique improves outcomes.
Severe pulmonary graft failure (PGF) is the most common cause of death within the first 30 days after lung transplantation. Extracorporeal membrane oxygenation (ECMO) may provide lifesaving temporary support; however, its longer-term efficacy is controversial. ⋯ Extracorporeal membrane oxygenation results have improved with advances in oxygenator technology and surgical techniques. The procedure can allow resolution of early PGF after lung transplantation.

This study evaluates the utility of positron emission tomography (PET), endoscopic ultrasonography (EUS), and computed tomographic (CT) scans to predict pathologic response and survival following preoperative chemoradiation (CRT) in esophageal cancer. ⋯ The FDG-PET SUV is the most accurate noninvasive test to predict long-term survival after preoperative CRT and before surgical resection. Post-CRT FDG-PET cannot, however, rule out residual microscopic disease so esophagectomy should remain a therapeutic option even if the post-CRT imaging modalities are normal.

Randomized Controlled Trial Comparative Study Clinical Trial
Papaverine delivery to the internal mammary artery pedicle effectively treats spasm.
Left internal mammary artery spasm is well recognized during coronary artery bypass operations. Papaverine has been used by many surgeons to maximize mammary artery flow perioperatively, but the best delivery method is not known. We analyzed two techniques used at our institution. ⋯ Papaverine delivery to the left internal mammary artery after dissection treats spasm effectively, improves blood flow at the time of its anastamosis to the left anterior descending artery, and avoids any risk of intimal injury. Injection of papaverine before mammary artery harvest does not shorten dissection time, and flow is not statistically improved.

We are analyzing our experience with treatment of desmoid tumors of the chest wall and adjacent structures. ⋯ Desmoid tumors involving the chest and adjacent structures are locally aggressive tumors with a high recurrence rate. Wide radical resection should be attempted whenever possible. Positive margins at resection, reoperation and postoperative radiation are associated with a high risk of local recurrence.
