食道外切開口から—歯科臨床に於て用いられるハンドピース用—裂溝樣バーをもつて—摘出した上顎全義齒食道異物症例

　まえがき

食道異物の抽出は極めて容易に成功することもあれば，この反面なかなかむつかしく万事意の如くにはこばないで，思わぬ苦労を重ねなければならないこともすくなくないものであるということは，食道異物患者に多少でも遭遇された御方なら誰しも経驗されるところであろう．

　私も過去20有余年にわたる臨床生活に於て今申述べたようないろいろな多くの症例に接してきたが，就中抽出に骨が折れた症例をふりかえつてみると，当時味わつた苦辛のほどが思い出されて感慨深いものがある．

Matsuda reports a case in whom, a farmer aged 64, was found with full upper denture lodged in the esophagus about 23 cm below the edge of upper incisor teeth. The denture was swallowed accidently. Under usual circumst-ances a foreign body of similar size would proceed no further downward in the alimentary tract than the lower border of pharynx or the beginning part of esophagus but, in the present case, previous unsuccessful attempts at removal had caused it to be driven further into that organ than it would have been otherwise. Endoscopical removal of the denture, which was provided with hook-like projection on its either side and the sharp ends of which were found to be firmly inserted into the wall of the esophagus in vertical alignment, was totally inadequate. It was finally removed when the denture was exposed through external approach on the esophagus and broken into several pieces by aid of dental instruments.
