Abstract

Background/Aims: Mucosal incision-assisted biopsy (MIAB) for tissue acquisition (TA) from subepithelial lesions (SELs) is emerging as an alternative to endoscopic ultrasound (EUS)-guided TA. Only a limited number of studies compared the diagnostic utility of MIAB and EUS for upper gastrointestinal (GI) SELs; therefore, we conducted this systematic review and meta-analysis.
Methods: A comprehensive literature search from January 2020 to January 2022 was performed to compare the diagnostic accuracy and safety of MIAB and EUS-guided TA for upper GI SELs.
Results: Seven studies were included in this meta-analysis. The pooled technical success rate (risk ratio [RR], 0.96; 95% confidence interval [CI], 0.89?1.04) and procedural time (mean difference=?4.53 seconds; 95% CI, ?22.38 to 13.31] were comparable between both the groups. The overall chance of obtaining a positive diagnostic yield was lower with EUS than with MIAB for all lesions (RR, 0.83; 95% CI, 0.71?0.98) but comparable when using a fine-needle biopsy needle (RR, 0.93; 95% CI, 0.83?1.04). The positive diagnostic yield of MIAB was higher for lesions <20 mm (RR, 0.75; 95% CI, 0.63?0.89). Six studies reported no adverse events.
Conclusions: MIAB can be considered an effective alternative to EUS-guided TA for upper GI SELs without an increased risk of adverse events.
