Perforation into the retroperitoneal space may occur during duodenoscopic sphincterotomy and can be recognized radiographically. While it is potentially serious, most patients should respond to conservative management provided that adequate biliary drainage is achieved. Five cases encountered during approximately 500 sphincterotomies are presented. Radiographs taken 24 hours after 50 additional procedures showed no evidence of perforation.
十二指肠镜括约肌切开术过程中可能会发生穿孔至腹膜后间隙，且可通过影像学检查识别。虽然这可能很严重，但只要实现了充分的胆道引流，大多数患者对保守治疗应会有反应。本文介绍了在大约500例括约肌切开术中遇到的5例病例。另外50例手术后24小时拍摄的X光片未显示穿孔迹象。
