WHAT IS BIOPSY (SITE-SPECIFIC) TETS?
Excisional biopsy (remove entire lump), incisional biopsy (remove part of lump), pinch biopsy (using forceps), snare excision (for large polyps) or needle punch or fine-needle aspiration (FNA) (a small sample is withdrawn through a 22- to 25-gauge needle) done under sterile technique and examined for cell morphology and tissue abnormalities. The procedure takes 15-30 minutes. Each specimen is evaluated by gross examination, by microscopic examination, and through tissue processing (staining and preserving). Adjunct brush cytology helps diagnose gastric malignancy of infection.
