A technique for removing polyps and diagnostic tissue from the gastrointestinal tract using an endoscope, obtained with standard forceps coated with plastic insulation and supplying monopolar electrocoagulation. Hot biopsies are obtained by grasping the mucosa, tenting it into the gastrointestinal lumen and heating for 1-2 seconds.
The tissue obtained may be uninterpretable because the tissue has been fried and the technique carries a theoretical risk of explosion if the amplitude and duration of the current is dialed up and there is enough methane in the GI tract.
Synonym Monopolar hot biopsy
