Peroral pneumocolon examination was performed on 40 patients for further radiographic evaluation of the terminal ileum after antegrade small bowel study. Patients were selected because of poor visualization of the terminal ileum on routine study (17 patients), clinically suspected Crohn disease but normal terminal ileum on routine study (ten), abnormal terminal ileum on routine study (seven), and previous ileocolic anastomosis (six). Use of the technique resulted in additional diagnostic information in 20 (50%) of the 40 patients. Its main value was in showing a previously poorly visualized terminal ileum to be normal (eight patients) and in confirming a normal terminal ileum in clinically suspected Crohn disease (six). In addition, it more precisely defined the proximal extent of recurrent ileal Crohn disease in two patients and detected otherwise unrecognized early ileal Crohn disease in one patient. The technique can be carried out immediately after any antegrade small bowel examination, and if reserved for the above indications, is a valuable adjunct to routine compression spot films of the terminal ileum or reflux study of the terminal ileum at barium enema.
对40例患者进行了经口气钡灌肠检查，以便在顺行性小肠造影后对回肠末端进行进一步的影像学评估。选择这些患者的原因如下：常规检查时回肠末端显影不佳（17例）；临床怀疑克罗恩病但常规检查时回肠末端正常（10例）；常规检查时回肠末端异常（7例）；既往有回结肠吻合术（6例）。该技术使40例患者中的20例（50%）获得了额外的诊断信息。其主要价值在于显示之前显影不佳的回肠末端正常（8例患者），以及在临床怀疑克罗恩病时确认回肠末端正常（6例）。此外，它更精确地界定了2例复发性回肠克罗恩病的近端范围，并在1例患者中检测到了原本未被识别的早期回肠克罗恩病。该技术可在任何顺行性小肠检查后立即进行，如果用于上述适应证，是对回肠末端常规压迫点片或钡剂灌肠时回肠末端反流造影的有价值辅助检查。
