It's just that this case is too complicated right now; the people in Radiology can't work it out in their heads.
Cup-shaped cases are the easiest to succeed with this method. When they run into difficult cases, because they can't calculate it mentally, most clinicians will resort to manual massage and repeated trial injections, basically groping around on experience like a blind cat blundering into a dead mouse.
Now these two young doctors are going back to the very essence of air enema, intending to calculate a set of precise procedural steps instead of trying things out? Is that even possible?
The problem with groping and trying is that it takes too long and you might not make it in time; better for the doctor to calculate everything in advance, adjust to the optimal, shortest pathway of steps, and then act. That would be a very elegant, almost perfect ideal plan. If it works, the others are thinking: that would be a miracle.
