Electrosurgical hot biopsy forceps coagulation: More (intensity) is less (complications)

摘要

I have read with interest the ESGE guideline on the use of electrosurgical units [1] and would like to make some comments. Hot biopsy forceps polypectomy (HBFP) is frequently criticized for its high frequency of complications. In fact, the main problem lies in an erroneous understanding of the effect of high frequency current (HFC) [1]. Impedance, it should be noted, is the appropriate concept to use with regard to HFC, and not resistance [2].
