Abstract

自験例を含むcholedochoceleの文献報告167例を検討し,choledochoceleの診断基準(私案)を以下のごとく作製した.<BR>胆管下部の十二指腸壁内での嚢状の拡張をcholedochoceleと称する.その多くは乳頭部胆管ないし共通管の拡張であるが,発生学的に胆管由来でない例も存在する.十二指腸内腔に滑脱する例も少なくない. 嚢腫最大径が1cm 以上である. 嚢腫内腔粘膜の組織像は問題としない.先天性だけでなく,後天性の要因もあるが,明らかな結石の乳頭部嵌頓や胆道の治療後の変化は除外する.膵・胆管合流異常を合併してもよい.共通管を形成する症例では,膵液と胆汁の相互逆流が起こりうるので,膵・胆管合流異常と同様の注意が必要である.

We analyzed 167 cases with choledochocele reported in the literature, and tried to make the diagnostic criteria of choledochocele as follows.<BR>Choledochocele is a cystic dilatation of the intraduodenal portion of the distal bile duct. In many cases, it is a cystic dilatation of ampullary bile duct or common channel. It sometimes protrudes into the duodenum depending upon its size. Its maximal diameter should be bigger than 1cm. The histology of the lining epithelium of the choledochocele is not significant. Though its etiology is congenital or acquired, cases with impacted bile duct stone, or changes after endoscopic sphincterotomy or extraction of biliary stone should be excluded. It may be associated with pancreaticobiliary maljunction. In choledochocele forming common channel, we should note the occurrence of the biliary carcinoma, due to reflux of pancreatic juice into the bile duct.
