Airway stenting in Japan

Teruomi Miyazawa; Ken-ichi Arita

Abstract Various types of outstanding airway stents have been made commercially available. In Japan, a total of 1004 airway stents (Dumon stents (Novatech, Aubagne, France), Gianturco Z stents (Cook Ins, Bloomington, USA), Ultraflex stents (Boston Scientific Corp, Natick, MA, USA), and Dynamic Y stents (Ruesch AG, Kernen, Germany)) were implanted from July 1991 until February 1998. Of all the various stents, the Dumon stent has become the standard worldwide. Also, the Dumon stent has been replacing the Gianturco Z stent as the preferred stent throughout Japan. The Dumon stent was the first stent covered by Japanese National Health Insurance. Therefore, we present our 5‐year experience with the Dumon stent at our institusion. In our experience, stenting is effective for the immediate and lasting relief of symptoms in patients with severe malignant obstruction of major airways.

背景. PPaciitaxel (以下TAX) の過敏反応は適切な前投薬を行うにもかかわらず起こることがある. 症例. 症例1は75歳女性. 肺腺癌stage IIIBと診断し, carboplatin (以下CBDCA) +TAX毎週投与法を開始した. 1コース目の投与初日, TAXの投与開始3分後に呼吸困難と喘鳴を生じた. TAXの投与を中止しmethyiprednisoioneを投与した結果, 速やかに症状は軽快した. 症例2は52歳男性. 肺腺癌stager IVと診断し, CBDCA+TAX毎週投与法の治療を開始した. TAXの投与2回目にあたる2コース目の初日, TAXの投与7分後より呼吸困難を生じ, TAX中止の上methyiprednisoioneとepinephrineを投与するも数分後に心肺停止となった. 蘇生術を行ったが, 蘇生後脳症をきたした. 2例とも前投薬を施行したにもかかわらず過敏反応を生じ, また2例ともTAX投与前に末梢血好酸球数が増加していた. 結論. TAXの過敏反応の予防にヒスタミン受容体拮抗剤と副腎皮質ホルモン剤を投与する方法は広く行われているが完全ではない. 重篤な転帰をたどる症例が存在することを認識しておくべきである.
