/Aims: This meta-analysis analyzed the effect of an indwelling biliary stent on endoscopic ultrasound (EUS)–guided tissue acquisition from pancreatic lesions.
A literature search was performed to identify studies published between 2000 and July 2022 comparing the diagnostic outcomes of EUS-TA in patients with or without biliary stents. For non-strict criteria, samples reported as malignant or suspicious for malignancy were included, whereas for strict criteria, only samples reported as malignant were included in the analysis.
Nine studies were included in this analysis. The odds of an accurate diagnosis were significantly lower in patients with indwelling stents using both non-strict (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.52–0.90) and strict criteria (OR, 0.58; 95% CI, 0.46–0.74). The pooled sensitivity with and without stents were similar (87% vs. 91%) using non-strict criteria. However, patients with stents had a lower pooled sensitivity (79% vs. 88%) when using strict criteria. The sample inadequacy rate was comparable between groups (OR, 1.12; 95% CI, 0.76–1.65). The diagnostic accuracy and sample inadequacy were comparable between plastic and metal biliary stents.
The presence of a biliary stent may negatively affect the diagnostic outcome of EUS-TA for pancreatic lesions.

/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.
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.
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.
MIAB can be considered an effective alternative to EUS-guided TA for upper GI SELs without an increased risk of adverse events.
