1. Post polypectomy fever is a diagnosis that can only be made after sufficient
verification of other causes of fever. Describe the abdominal CT scan and blood
culture results in more detail. It seems important to present the results even if
there are no abnormalities on the examination.
2. It is hypothesized that the cause of PPF is transient bacteremia, bacterial
translocation, or a mild form of postcoagulation syndrome. In the end, it can be
interpreted as a story that mucosal damage affects intestinal bacteria or there is
minimal barrier damage. In the case of a 50-year-old female patient, the size of
the polyp is small and it appears to have been removed with a cold snare or
forceps. Still, what do you think is the cause of PPF? In the case of Cited Paper
No. 5, the size of the polyp is large, so it seems reasonable to explain the
mucosal damage and bacterial translocation, but in your case, the size of the
polyp is too small.
3. Looking at the figure of the second case, it seems that argon plasma
coagulation was performed, is this correct? Is it common to perform argon
plasma coagulation when removing polyps? Please explain clearly.
