Endoscopic ultrasound fine needle aspiration fine needle biopsy in solid lesions: A multi-center analysis.

Background: While endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is considered a preferred technique for tissue sampling for solid lesions, fine needle biopsy (FNB) has recently been developed.

Aim: To compare the accuracy of FNB FNA in determining the diagnosis of solid lesions.

Methods: A retrospective, multi-center study of EUS-guided tissue sampling using FNA FNB needles.

Laparoscopic SpyGlass cholangioscopy evaluation during bilioenteric anastomosis for hepatolithiasis, a case report.

Introduction: Careful evaluation of intrahepatic injury of biliary tract diseases is crucial to assure proper management and estimate disease prognosis. Hepatholithiasis is a rare condition that can be associated to cholestatic liver diseases. Additional tools to improve diagnosis and patient care are of great interest specially if associated to decreased morbidity.

Evaluation of endoscopic ultrasound fine-needle aspiration versus fine-needle biopsy and impact of rapid on-site evaluation for pancreatic masses.

 Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is traditionally considered a first-line strategy for diagnosing pancreatic lesions; however, given less than ideal accuracy rates, fine-needle biopsy (FNB) has been recently developed to yield histological tissue. The aim of this study was to compare diagnostic yield and safety between EUS-FNA and EUS-FNB in sampling of pancreatic masses.  This was a multicenter retrospective study to evaluate efficacy and safety of EUS-FNA and EUS-FNB for pancreatic lesions.

Efficacy and Safety of Endoscopic Sleeve Gastroplasty at Mid Term in the Management of Overweight and Obese Patients: a Systematic Review and Meta-Analysis.

Background: Endoscopic sleeve gastroplasty (ESG) has emerged as a promising technique in endoscopic bariatric and metabolic therapies (EBMTs). We aimed to perform a systematic review and meta-analysis to provide an update on its efficacy and safety.

Methods: This is a systematic review and meta-analysis was performed following the PRISMA guidelines.

The First Study Evaluating Effectiveness and Safety of the Endoscopic Sleeve Gastroplasty in HIV Patients.

The authors evaluated, retrospectively, the endoscopic sleeve gastroplasty impact in seven HIV patients, regarding effectiveness and safety outcomes. The mean baseline body mass index (BMI) was 33.76 kg/m.

Gastrointestinal ischemia: endoscopic findings in the context of vascular insufficiency.

Gastrointestinal ischemia may result from different causes: hemodynamic shock, thromboembolism, endoscopic or surgical complications, among other causes. Its symptoms are pain, vomiting, bleeding and bloating. Endoscopic findings are pale or blackened mucosa, and exudative and confluent ulcerative lesions.

Narrow-band imaging for scar (NBI-SCAR) classification: from conception to multicenter validation.

Background And Aims: Surveillance post-endoscopic resection (ER) currently warrants biopsy samples from the resection site scar in most cases, although clinical practice is variable. A classification with standard criteria for scars has not yet been established. We aimed to create and validate a novel classification for post-ER scars by using specific criteria based on advanced imaging.

Endoscopic ultrasound-guided endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis.

Background: For palliation of malignant biliary obstruction (MBO), the gold-standard method of biliary drainage is endoscopic retrograde cholangiopancreatography (ERCP) with the placement of metallic stents. Endoscopic ultrasound (EUS)-guided drainage is an alternative that is typically reserved for cases of ERCP failure. Recently, however, there have been robust randomized clinical trials (RCTs) comparing EUS-guided drainage and ERCP as primary approaches to MBO.

Endoscopic Dilation with Bougies versus Balloon Dilation in Esophageal Benign Strictures: Systematic Review and Meta-Analysis.

Background: The use of bougies and balloons to dilate benign esophageal strictures (BES) is a consolidated procedure. However, the amount of evidence available in scientific literature supporting which is the best technique is very low, despite the great prevalence and importance of such pathology. This systematic review with meta-analysis aims at comparing both techniques, providing good quality of evidence.

The Effectiveness of Endoscopic Gastroplasty for Obesity Treatment According to FDA Thresholds: Systematic Review and Meta-Analysis Based on Randomized Controlled Trials.

Endoscopic bariatric therapies (EBTs) are promising alternatives to conventional surgery for obesity. The aim of this study is to compare efficacy and safety through a systematic review and meta-analysis of the endoscopic gastroplasty techniques versus conservative treatment. We searched MEDLINE, EMBASE, Cochrane CENTRAL, Lilacs/Bireme.
