Effectiveness of HPD and Radiation Therapy in Lung Cancer

The diagnostic rate of lung cancer has been improved by the development of the fiberoptic bronchoscope and this instrument has particularly promoted the detection of early stage of central type lung cancer. But therapeutic results have been unsatisfactory, partly because of difficulties in resecting cases with poor pulmonary function. On the other hand, chemotherapy and radiation therapy can have serious side effects. New therapeutic modalities are therefore required for treatment of early stage inoperable lung cancer cases.

Unilateral Intubation as Emergency Treatment for Carinal Stenosis

Large airway stenosis requires emergency treatment because of the critical condition. Usually tracheal intubation is useful for such a case. But, for carinal stenosis unilateral intubation is necessary. However, for a conscious patient unilatelar intubation with the regular intubation tube is difficult. In our department, we newly design a special tracheal cannula for such carinal stenosis cases using the regular intubation tube and the tracheal cannula. Manufacture of this special cannula is simple, economical and can be done in almost any hospital. The cannula is easy to fix and is stable for a relatively long period, for example 3 to 4 weeks for radiation treatment.
