小腸内視鏡検査後の小腸X線造影用ゾンデ（福大筑紫式）の考案とその使用成績

Newly Devised Small Bowel Sonde for Air Contrast Barium Study after Enteroscopy

要旨　小腸内視鏡検査後の小腸X線造影用ゾンデ（福大筑紫式と呼称）を考案し，その使用成績を明らかにした．対象はCrohn病15例，非特異性多発性小腸潰瘍症1例で，小腸内視鏡検査後，福大筑紫式小腸X線造影用ゾンデで造影し，内視鏡観察不能な口側・肛門側の病変の有無，性状，範囲などを検討した．小骨盤腔内に高度狭窄があるCrohn病の1例を除く14例で，広汎に良好なX線二重造影が得られた．描出された病変は，狭窄，潰瘍，アフタなど様々であり内視鏡で観察できない小腸の評価に簡便で有用であった．

　We devised a sonde for small bowel double contrast study after enteroscopy and demonstrated favorable results of visualization of oral side lesions. The subjects were 15 patients with Crohn's disease and 1 patient with nonspecific multiple ulcers of the small intestine. After enteroscopy we performed a double contrast examination of the small bowel with the sonde and investigated whether specific lesions were present at the oral or anal sides, where enteroscopic examination was impossible. Good double contrast study was achieved safely in 14 of the Crohn's disease cases, excluding a Crohn's disease patient with severe stenosis in the narrow pelvic cavity. Various lesions were visualized, including stenosis, ulcers, and aphthae, and it was convenient and useful for evaluation of the small intestinal lesions that could not be examined endoscopically.
