Fine-Needle Aspiration Biopsy and Endoscopic Ultrasound for Pretreatment Pathological Diagnosis of Gastric Gastrointestinal Stromal Tumors
Figure 2
Consistency of pathological diagnosis between biopsy and surgical specimens. All 34 biopsies were categorized by presence of EUS and FNAB as EUS-guided FNA biopsy (EUS+/FNAB, 10 biopsies), forceps biopsy with EUS (EUS+/forceps, 2 biopsies), FNA biopsy without EUS (EUS−/FNAB, 3 biopsies), and forceps biopsy without EUS (EUS−/forceps, 19 biopsies). The EUS+/FNAB group had significantly better diagnostic accuracy than the EUS−/FNAB and EUS−/forceps groups ( and ). Although this difference was not statistically significant, the EUS+/FNAB group had better accuracy than the EUS+/forceps group.
