Safety and efficacy of over-the-scope clips versus standard therapy for high-risk nonvariceal upper GI bleeding: systematic review and meta-analysisUpper GI bleeding (UGIB) is a common condition associated with significant morbidity and mortality. Endoscopic hemostasis remains the mainstay of therapy and is mainly aimed at effective hemostasis and prevention of rebleeding. Lesions with high-risk stigmata can have rebleeding rates of as high as 26.3%. Rebleeding is associated with increased mortality and reduced success rates of endoscopic retreatment. The over-the-scope-clip (OTSC) is a device with widespread endoscopic indications including hemostasis for nonvariceal UGIB (NVUGIB).
Clip closure to prevent adverse events after EMR of proximal large nonpedunculated colorectal polyps: meta-analysis of individual patient data from randomized controlled trialsAfter EMR, prophylactic clipping is often performed to prevent clinically significant post-EMR bleeding (CSPEB) and other adverse events (AEs). Prior evidence syntheses have lacked sufficient power to assess clipping in relevant subgroups or in nonbleeding AEs. We performed a meta-analysis of individual patient data (IPD) from randomized trials assessing the efficacy of clipping to prevent AEs after EMR of proximal large nonpedunculated colorectal polyps (LNPCPs) ≥20 mm.
Comparative diagnostic performance of end-cutting fine-needle biopsy needles for EUS tissue sampling of solid pancreatic masses: a network meta-analysisEvidence 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.
Comparative efficacy of different methods for difficult biliary cannulation in ERCP: systematic review and network meta-analysisSeveral methods with variable efficacy have been proposed for difficult biliary cannulation in ERCP. We assessed the comparative efficacy of different strategies for difficult biliary cannulation through a network meta-analysis combining direct and indirect treatment comparisons.
Role of routine second-look endoscopy in patients with acute peptic ulcer bleeding: meta-analysis of randomized controlled trialsStudies evaluating the role of routine second-look endoscopy in patients with acute upper GI bleed because of peptic ulcer disease (PUD) have reported conflicting results. This meta-analysis evaluates the usefulness of routine second-look endoscopy in these patients.
Prophylactic clips to reduce delayed polypectomy bleeding after resection of large colorectal polyps: a systematic review and meta-analysis of randomized trialsProphylactic clips to prevent delayed polypectomy bleeding (DPB) after endoscopic resection of large colorectal polyps remains controversial. We performed a systematic review and meta-analysis to evaluate the efficacy of prophylactic clips for preventing DPB by synthesizing the results of randomized trials.
Comparison of EUS-guided endoscopic transpapillary and percutaneous gallbladder drainage for acute cholecystitis: a systematic review with network meta-analysisThe optimal method of gallbladder drainage (GBD) for acute cholecystitis in nonsurgical candidates is uncertain. The aim of the current study was to conduct a network meta-analysis comparing the 3 methods of GBD (percutaneous [PT], endoscopic transpapillary [ETP], and EUS-guided).
Incidence of metachronous cancer after endoscopic submucosal dissection: a comparison between undifferentiated-type and differentiated-type early gastric cancerEndoscopic submucosal dissection (ESD) has become an important and minimally invasive treatment for early gastric cancer (EGC) with a negligible risk of metastasis not only for differentiated-type (D-type) cancer but also for undifferentiated-type (UD-type) cancer. We aimed to investigate the incidence and characteristics of metachronous cancer after ESD for UD-type cancer, which has not yet been elucidated.
Performance of artificial intelligence in colonoscopy for adenoma and polyp detection: a systematic review and meta-analysisOne-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.
Associations between endoscopist feedback and improvements in colonoscopy quality indicators: a systematic review and meta-analysisColonoscopy quality indicators such as adenoma detection rate (ADR) are surrogates for the effectiveness of screening-related colonoscopy. It is unclear whether endoscopist feedback on these indicators improves performance. We performed a meta-analysis to determine whether associations exist between endoscopist feedback and colonoscopy performance.
Efficacy and cost-effectiveness of fecal immunochemical test versus colonoscopy in colorectal cancer screening: a systematic review and meta-analysisThe fecal immunochemical test (FIT) and colonoscopy are the most commonly used strategies for colorectal cancer (CRC) screening worldwide. We aimed to compare their efficacy and cost-effectiveness in CRC screening in an average-risk population.
Comparative efficacy of per-oral endoscopic myotomy and Heller myotomy in patients with achalasia: a meta-analysisAlthough both per-oral endoscopic myotomy (POEM) and Heller myotomy (HM) have been used for the treatment of achalasia, the comparative efficacy of POEM and HM has yet to be fully evaluated.
Meta-analysis of dye-based chromoendoscopy compared with standard- and high-definition white-light endoscopy in patients with inflammatory bowel disease at increased risk of colon cancerPatients with ulcerative colitis have an increased risk of colorectal cancer. We sought to assess the comparative efficacy of standard white-light endoscopy (SDWLE) or high-definition white-light endoscopy (HDWLE) versus dye-based chromoendoscopy through a meta-analysis and rate the quality of evidence using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system.
Persistent intestinal metaplasia after endoscopic eradication therapy of neoplastic Barrett’s esophagus increases the risk of dysplasia recurrence: meta-analysisEndoscopic eradication therapy (EET) is the main treatment for dysplastic Barrett’s esophagus and intramucosal adenocarcinoma. Although the goal of EET is to achieve complete remission of intestinal metaplasia (CRIM), treatment might achieve complete remission of dysplasia (CR-D) only, without achieving CRIM. Persistent intestinal metaplasia after eradication of dysplasia might carry a higher risk for progression into advanced neoplasia.
