Precut mucosectomy versus endoscopic resection techniques for colorectal lesions sized 10-30 mm: meta-analysis and systematic review.

Background: Early-stage colorectal lesions are traditionally managed with conventional endoscopic mucosal resection (EMR-C). Endoscopic submucosal dissection (ESD), though technically demanding, enables en bloc resection with negative margins. Precut mucosectomy (EMR-P) was developed to enhance en bloc resection rates by minimizing the risk of snare slippage during procedures.

Endoscopic Ultrasound-guided Drainage With Lumen-apposing Metal Stent versus Plastic Stent for the Treatment of Pancreatic Pseudocyst: A Systematic Review and Meta-analysis.

Background: Pancreatic pseudocyst (PP), following acute or chronic pancreatitis, may become symptomatic or persist beyond 6-8 weeks, requiring drainage. Endoscopic ultrasonography-guided drainage (EUS-D) is the preferred method, using double pigtail plastic stents (DPPS) or self-expandable metallic stents (SEMS), such as lumen-apposing metal stents (LAMS). This meta-analysis compares DPPS and LAMS in EUS-D for PP, focusing on technical success, clinical success, adverse events (AEs), recurrence, and procedure time.

Covered Self-Expanding Metal Stents Versus Multiple Plastic Stents in Treating Biliary Strictures Post-Orthotopic Liver Transplantation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objectives: Anastomotic biliary strictures are a common complication following orthotopic liver transplantation (post-OLT), impacting morbidity and graft survival. This meta-analysis evaluates the efficacy, safety, and cost-effectiveness of covered self-expanding metal stents (cSEMS) versus multiple plastic stents (MPS) for treating post-OLT strictures.

Methods: A systematic review was conducted in PubMed, Cochrane Central, Embase, Scholar, and SciELO.

Effectiveness and Safety of the Allurion Swallowable Intragastric Balloon for Short-term Weight Loss: A Systematic Review and Meta-analysis.

Background: Obesity poses a severe health problem worldwide, with an estimated impact on 17.5% of the adult population by 2035. Among the endoscopic applications for treating this comorbidity, intragastric balloons are the most widely used.

Radiofrequency ablation for ampullary neoplasia with intraductal extension after endoscopic papillectomy: Systematic review and meta-analysis.

Noninvasive ampullary neoplasms may be removed by surgery or endoscopy. However, given the morbidity and mortality associated with surgery, endoscopic papillectomy (EP) is the preferred approach. Radiofrequency ablation (RFA) after EP has emerged as a promising alternative therapy to avoid surgery after incomplete EP.

Correction: Intraductal radiofrequency ablation plus biliary stent versus stent alone for malignant biliary obstruction: a systematic review and meta-analysis.

Intraductal radiofrequency ablation plus biliary stent versus stent alone for malignant biliary obstruction: a systematic review and meta-analysis.

Recurrent biliary stent occlusion and tumor ingrowth remain a major concern among patients with malignant biliary obstruction (MBO) with significant impact on patient morbidity and survival. Intraductal radiofrequency ablation (RFA) has emerged as a promising treatment that seeks to extend stent patency. This study aimed to evaluate the impact of RFA on overall survival (OS) and stent patency among patients with unresectable MBO.

Endoscopic ultrasound artificial intelligence-assisted for prediction of gastrointestinal stromal tumors diagnosis: A systematic review and meta-analysis.

Background: Subepithelial lesions (SELs) are gastrointestinal tumors with heterogeneous malignant potential. Endoscopic ultrasonography (EUS) is the leading method for evaluation, but without histopathological analysis, precise differentiation of SEL risk is limited. Artificial intelligence (AI) is a promising aid for the diagnosis of gastrointestinal lesions in the absence of histopathology.

USE OF METABOLOMICS TO THE DIAGNOSIS OF INFLAMMATORY BOWEL DISEASE.

Background: Crohn's disease and ulcerative colitis are the primary inflammatory bowel diseases (IBD), and its pathogenesis is related to genetic and environmental factors. Currently, the diagnosis of IBD results in a multidisciplinary approach with significant disadvantages, such as its invasive nature, time spent, and the fact that 10% of patients remain without diagnostic classification. However, new methodologies of analysis have emerged that allowed the expansion of knowledge about IBD, as the metabolomics, the study of metabolites.
