- Evidence is limited on the comparative diagnostic performance of newer end-cutting fine-needle biopsy (FNB) needles for tissue sampling of pancreatic masses. We performed a systematic review with network meta-analysis to compare the diagnostic accuracy of available FNB needles for sampling of solid pancreatic lesions.
- One-fourth of colorectal neoplasia are missed at screening colonoscopy, representing the main cause of interval colorectal cancer. Deep learning systems with real-time computer-aided polyp detection (CADe) showed high accuracy in artificial settings, and preliminary randomized controlled trials (RCTs) reported favorable outcomes in the clinical setting. The aim of this meta-analysis was to summarize available RCTs on the performance of CADe systems in colorectal neoplasia detection.
- Hot snare polypectomy and EMR are the standard of care in resecting colorectal polyps ≥10 mm. To avoid the risk of electrocautery-induced damage, there is recent evidence about using cold snare polypectomy and cold EMR for such lesions. The aim of this pooled analysis is to report outcomes of cold snare resection for polyps ≥10 mm.
- Underwater EMR is an alternative way to have nonpedunculated colorectal lesions lifted before being resected. The endoscopist takes advantage of the behavior of mucosal lesions floating away from the muscular layer, once immersed in liquid. We performed a systematic review with meta-analysis to evaluate the efficacy and safety of this technique.
- Water-aided colonoscopy techniques, such as water immersion (WI) and water exchange (WE), have shown different results regarding adenoma detection rate (ADR). We determined the impact of WI and WE on ADR and other procedural outcomes versus gas (air, AI; CO2) insufflation colonoscopy.
- Devices used to improve polyp detection during colonoscopy have seldom been compared with each other.
- EUS elastography is useful in characterizing solid pancreatic lesions (SPLs), and fractal analysis–based technology has been used to evaluate geometric complexity in oncology. The aim of this study was to evaluate EUS elastography (strain ratio) and fractal analysis for the characterization of SPLs.
- Focal EMR followed by radiofrequency ablation (f-EMR + RFA) and stepwise or complete EMR (s-EMR) are established strategies for eradication of Barrett's esophagus (BE)-related high-grade dysplasia (HGD) and/or esophageal adenocarcinoma (EAC)/intramucosal carcinoma (IMC). The objective of this study was to derive pooled rates of efficacy and safety of individual methods in a large cohort of patients with BE and to indirectly compare the 2 methods.
