BACKGROUND AND AIMS: Peptic ulcer disease (PUD)-related gastric outlet obstruction (GOO) is known to respond favorably to endoscopic balloon dilation (EBD). However, data on efficacy of EBD for other etiologies of benign GOO is sparse. We aimed to compare response of EBD among different etiologies of GOO. METHODS: Records of all patients with benign GOO who underwent EBD at our tertiary care center between January 1998 to December 2017 were analyzed. Dilation was done using through-the-scope balloons...

BACKGROUND AND AIMS: Gastrointestinal angiectasia (GIA) is the most common small-bowel (SB) vascular lesion, with an inherent risk of bleeding. SB capsule endoscopy (SB-CE) is the currently accepted diagnostic procedure. The aim of this study was to develop a computer-assisted diagnosis (CAD) tool for the detection of GIA. METHODS: Deidentified SB-CE still frames featuring annotated typical GIA and normal control still frames, were selected from a database. A semantic segmentation images approach associated with a convolutional neural network (CNN) was used for deep feature extractions and classification...

BACKGROUNDS AND AIMS: Delayed gastric transit of the capsule may lead to incomplete small bowel examination, reducing the diagnostic yield. Thus this study was designed to determine if magnetic steering could enhance capsule gastric emptying and mucosal visualization within the duodenum. METHODS: The intervention group comprised 100 patients undergoing magnetic-controlled capsule endoscopy (MCE) between May to September 2017 in whom magnetic control was used to assist transpyloric passage of the capsule and duodenal inspection...

BACKGROUND AND AIMS: Anastomotic biliary strictures (ABSs) are one of the most frequent adverse events that occur after orthotopic liver transplantation (OLT). Multiple plastic stents (MPSs) have been validated for this indication. More recently, fully covered self-expandable metallic stents (FCSEMSs) have been used with positive outcomes, but also have a higher rate of migration, which may limit success. Our primary objective was to compare stent migration rates observed with "standard" FCSEMSs (Std-FCSEMSs) and so-called "anti-migration" FCSEMSs (Am-FCSEMSs), which are newly designed with reversed proximal side flaps...

BACKGROUND AND AIMS: Water-aided colonoscopy techniques (water immersion, WI; 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; carbon dioxide, CO2 ) insufflation colonoscopy. METHODS: Systematic search of multiple databases for randomized controlled trials comparing WI and/or WE with AI and/or CO2 and reporting ADR. A network meta-analysis with mixed comparisons was performed...

BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-guided FNA) is an accurate and relatively safe tissue confirmation method for pancreatic cancer. However, there is concern that this procedure may spread tumor cells along the needle track or within the peritoneum. We aimed to estimate the effect of preoperative EUS-guided FNA on the risk of peritoneal recurrence and long-term outcomes in resected pancreatic cancer. METHODS: We retrospectively reviewed records of patients diagnosed with pancreatic cancer who had undergone curative resection between 2009 and 2013 to investigate the overall survival, cancer-free survival, and peritoneal recurrence...

BACKGROUND AND AIMS: The diagnosis of low-grade dysplasia (LGD) in Barrett's esophagus (BE) is subject to substantial interobserver variation. Our central aim in this study is to compare independent pathology practices using objective measures of BE risk stratification proficiency, including frequency of diagnosis and rate of progression to high-grade dysplasia (HGD) or adenocarcinoma (EAC) after the first diagnosis of LGD. METHODS: We retrospectively evaluated over 29,000 endoscopic biopsy cases to identify 4734 patients under endoscopic biopsy surveillance for BE in a health care system with multiple independent pathology practices: a subspecialized GI pathology group (SSGI; 162 BE cases per pathologist annually), 3 high BE volume general surgical pathology practices (GSPs; >50 BE cases per pathologist annually) and multiple low BE volume GSPs (10...

OBJECTIVE: Patients presenting with non-hematemesis GI bleeding represent a diagnostic challenge for physicians. We performed a randomized controlled trial to assess the benefits of deployment of a video capsule soon after admission in the management of patients presenting with melena, hematochezia, or severe anemia compared with standard of care management. DESIGN: Patients admitted with non-hematemesis GI bleeding were randomized and placed into one of 2 study groups...

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is safe and effective for eradicating Barrett's esophagus (BE), but associated with significant postprocedural pain. Alternatively, balloon-based focal cryoablation (CRYO) has recently been developed, which preserves the extracellular matrix and might therefore be less painful. Although data for CRYO are still limited, uncontrolled studies suggest comparable safety and efficacy to RFA in eradicating limited BE areas. Therefore, secondary endpoints such as pain might become decisive for treatment selection...

We review our approach to resection of colorectal polyps <20 mm in size. Careful inspection of all lesions is appropriate to assess the type of lesion (adenoma vs serrated) and evaluate the risk of cancer, which is highly associated with lesion size. Polyp resection is in the midst of a "cold revolution," particularly for lesions <10 mm in size, but also for some larger lesions. Cold forceps are sometimes appropriate for 1- to 2-mm lesions that can be engulfed in one bite, but we use cold snaring for almost the entire set of lesions <10 mm...

OBJECTIVES: Although colonoscopy is the criterion standard for detection of colorectal adenomas, some adenomas are missed. Full-spectrum endoscopy (FUSE) allows for observation with a 330° angle of view, which is expected to decrease the miss rate. However, no consensus has been reached regarding the superiority of FUSE over standard forward-viewing colonoscopy (SFVC) for detection of adenomas; we therefore compared new-generation FUSE and SFVC regarding colorectal adenoma miss rate (AMR) in this, the first reported randomized control trial using new-generation FUSE...

BACKGROUND AND AIMS: For young individuals (<40) without strong family histories that would put them at risk for genetic colorectal cancer syndromes, it is unclear if national Multi-Society Task Force surveillance recommendations apply or if endoscopists follow these guideline recommendations when such patients are incidentally found to have adenoma(s) on colonoscopy. METHODS: We reviewed records on young (<40-year-old) patients, with either no family history or only a "moderate" family history (one first-degree family member with colorectal cancer at age ≥50), who were found to have neoplastic polyp(s) on their index colonoscopy...
