要約 目的:ヌンチャク型シリコーンチューブ(NST)とその付属ブジーを一体化したプローブを使った涙小管閉塞治療の報告。対象と方法:鼻涙管閉塞がない涙小管閉塞患者17例20側を対象とした。シリコーンプローブで閉塞部の穿破のあとNSTを挿入し,約2か月後に抜去した。一部に涙小管トレパンまたは金属ブジーを併用した。結果:19側(95%)でNSTを挿入できた。涙小管トレパンを5側,金属ブジーを2側に使用した。NSTの抜去後平均6か月の観察で17側では通水良好であり,再閉塞が2側に生じた。うち1側ではシリコーンプローブで再度穿破を行い,通水良好になった。結論:今回の方法で,涙小管閉塞に対し低侵襲で高い成功率が得られた。
Abstract. Purpose:To report treatment of canalicular obstruction using a probe attached to nunchaku-style silicone tube(NST). Cases and Method:A total of 20 sides in 17 patients were treated by this method. NST was inserted after perforation of the obstructed site by a silicone probe. NST was removed 2 months later. Some cases were also treated by canalicular trephining or metal bougie. Results:NST was successfully inserted in 19 sides(95%). Five sides received canalicular trephining and metal bougie was used in 2 sides. Passage of tear fluid was patent in 17 sides during the follow-up for 6 months after removal of NST. Canalicular obstruction recurred in 2 sides. One side was perforated using a silicone probe and resulted in patent lacrimal passage. Conclusion:The present method induced passage of obstructed canaliculus at a high rate of success with minimum insult.
