A new device for the identification of lymph nodes at lung cancer surgery.

In order to provide a precise lymph node mapping during lung cancer surgery a sterilizable plastic tray moulded in the shape of the mediastinum and lungs is presented by the author. The device makes lymph node mapping simpler, safer, quicker and methodically more structured. A positive impact is expected as a result of usage of the device from making pathologist's work easier and facilitating the flux of information on the surgeon-pathologist-oncologist-pneumonologist chain to be more disinformation-free.

Lung biopsy using harmonic scalpel: a randomised single institute study.

OBJECTIVE: Applicability of harmonic scalpel in lung biopsy was investigated in a randomised single institute study. METHODS: Safety of the method, morbidity, drainage duration and in-hospital stays were compared in two randomised groups of patients in which either ultrasonic harmonic scalpel (n:20) or endostapler (n:20) were used for pulmonary biopsies during VATS. RESULTS: An advantage of 16min in average operation time was found in favour of the harmonic scalpel (30.75 vs 46.9min) which was significant. There were no differences in average drainage duration (40.2 vs 30.6h) and pleural fluid volume (258 vs 232ml). Minor complication rates (3 vs 3) were identical and in-hospital stays (7.6 vs 7.2 days) were also similar. CONCLUSIONS: Overall, the vibration transmission method was shown not to be inferior to the standard endostapling technique. A safe new method offers an alternative technique for peripherial lung biopsy.

Cutting lung parenchyma using the harmonic scalpel--an animal experiment.

OBJECTIVE: Applicability of harmonic scalpel in lung surgery was investigated using an animal model. METHODS: Air tightness, control of bleeding and features of tissue regeneration were compared in a 4-week time frame of investigation in animals in which either surgical stapler or harmonic scalpel were used for pulmonary resection. RESULTS: No significant differences between the two methods were found on a clinical and histopathological basis. CONCLUSIONS: Complete lack of granuloma formation at the resection line and in its vicinity consequently restitutio ad integrum demonstrate the advantage of the harmonic scalpel over the stapler in the circumstances investigated. Overall the vibration transmission method was shown not to be inferior to the standard methods in peripheral lung tissue resection.

Changing dogmas: history of development in treatment modalities of traumatic pneumothorax, hemothorax, and posttraumatic empyema thoracis.

Development of treatment modalities for chest wounds and traumatic empyema thoracis is reviewed in the light of war experience. Mortality from thoracic injury was more than 50% before World War I and was about 25% during World War I. It came down to 10% in World War II and was about 5% during the Korean War. It improved further during the Vietnam War, until it ranged at 2% to 4%, where no further improvement could be imagined. Thoracic surgery was born in the field hospitals of World War I. Established drainage methods and standardized anesthesia made thoracotomy a standard procedure in World War II. As experience increased in chest trauma, surgical aggression diminished. Drainage ruled primary chest trauma treatment algorithms during the Vietnam War and coexisted with the full arsenal of cardiothoracic surgery when it was needed. Optimization of thoracic surgical aggression includes a case-tailored approach when major chest surgery with or without interventions on the central cardiovascular system is needed. This is where we are now, provided a proper logistic, Medevac system exists. If we let the past fade away, the danger of committing the mistakes of our predecessors increases without having their excuses. Our present is only the past of the future.
