胃・十二指腸潰瘍の穿孔

Perforation Due to Gastric and Duodenal Ulcers

　表題のようなテーマをひきうけたとき，実のところいささか困った．胃，十二指腸潰瘍の穿孔は，内科医にとっても，きわめて重要な問題ではあるが，実際にその処理に直接あたる外科側と異なり，なにぶん資料に乏しいからである．そこでこれを機会に，潰瘍の穿孔に関する全国調査を行ない，最近の動向を知るとともに，過去の報告と比較し，検討してみることにした．幸い多くの先生方の御厚意によって貴重な資料が寄せられ，まとめることができた．ここに厚くお礼申しあげたい．

　以下，アンケートから得た結果にもとづき，それぞれの項目ごとに若干の考察を加えながら述べる．

　Statistical analyses of perforation in gastric and duodenal ulcers have been attempted on a nationside scale during the six years from 1965 to 1970.

　Collected cases of perforation due to gastric ulcer amounted to 235 and those of duodenal origin to 491.

　By correlating ulcers of the stomach with those of duodenum, the authors have investigated them in detail as to chronological changes in the occurrence of perforation, its incidence as determined by sex, age and regional distribution, its initial symptoms, predisposing causes, the percentage of correct diagnosis prior to operation, significance of erroneous diagnosis, the relationship of prognosis with the length of time elapsed since its first examination up to surgical correction.
