AIM: Vedolizumab, a monoclonal antibody resulting in gut-selective anti-inflammatory activity, was FDA-approved in 2014 for use in patients with Crohn's disease (CD). The aim of the study was to investigate the efficacy of vedolizumab as a rescue therapy when other medical therapies have failed. METHOD: A retrospective review was performed on consecutive CD patients receiving vedolizumab between May 2014 and March 2016 at the Penn State Hershey IBD Center. These patients were unresponsive or intolerant to TNF antagonist therapy, and previously would have been surgical candidates...

BACKGROUND: Denervation of the pylorus after oesophagectomy is considered the principal factor responsible for delayed gastric emptying. Several studies have attempted to delineate whether surgical or chemical management of the pylorus during oesophagectomy is of benefit, but with conflicting results. The aim of this multicentre study was to assess whether there was any difference in outcomes between different approaches to management of the pylorus. METHODS: A prospectively maintained database was used to identify patients who underwent oesophagectomy for malignancy...

PURPOSE: The current management options of congenital pyriform aperture stenosis (CNPAS) are either conservative measures awaiting further growth of the bony nasal framework or surgical intervention that focuses on bone removal from the margin of the pyriform aperture (PA) without exposure of the nasolacrimal duct (NLD) followed by stenting. Recently, CT measurements of the nasal cavity in CNPAS have shed light that the site of maximal bony obstruction corresponds to the bony buttress encasing the NLD rather than the margin of the PA as initially thought...

Standardized approach to polypectomy of diminutive colorectal polyps (DCPs) is lacking since cold biopsy forceps have been associated with high levels of recurrence, hot biopsy forceps are considered inadequate and risky and cold snaring is currently under investigation for its efficacy and safety. This has led to confusion and a gap in clinical practice. This article discusses the usefulness and contemporary practical applicability of hot biopsy forceps and provides well-intentioned criticism of the new European guidelines for the treatment of DCPs...

Upper gastrointestinal (GI) bleeds are a common presentation to emergency departments in the UK. The Glasgow Blatchford score (GBS) predicts the outcome of patients at presentation. Current UK and European guidelines recommend outpatient management for a GBS of 0. In the current study, our aim was to assess whether extending the GBS allows for early discharge while maintaining patient safety. We also analysed whether pathologies could be missed by discharging patients too early. Data were retrospectively collected on patients admitted with symptoms of an upper GI bleed between 1 October 2013 and 10 June 2016...

BACKGROUND: Iron deficiency anemia (IDA) and abdominal pain are commonly seen in a pediatric emergency department (8 and 18% incidence respectively in our center). They are manifestations of a wide variety of diseases ranging from benign to immediately life-threatening. Trichobezoar is an under-diagnosed entity that has to be considered in children and adolescents, expecially female, suffering from trichotillomania (compulsion to pull hair) and trichophagy (compulsion to swallow hair)...

Despite nutrition interventions, stunting thought to be secondary to underlying environmental enteropathy (EE) remains pervasive among infants residing in resource-poor countries and remains poorly characterized. From a birth cohort of 380 children, 65 malnourished infants received 12 weeks of nutritional supplementation with ready-to-use therapeutic food (RUTF). Eleven children with insufficient response to RUTF underwent upper endoscopy with duodenal biopsies, which were compared with U.S., age-matched specimens for healthy, celiac disease, non-celiac villous atrophy, non-celiac intraepithelial lymphocytosis, and graft-versus-host disease patients...

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure...

Capsule endoscopy (CE) enables noninvasive visualization of the small bowel in Crohn's disease (CD), but should not be conducted in patients with bowel obstruction. Patency capsule (PC) can be ingested before conducting the CE examination to ensure patency of the gastrointestinal (GI) tract. This study aimed to evaluate the clinical significance of GI patency which the PC demonstrated. A retrospective review of the medical records was conducted with 99 consecutive patients with CD who underwent PC and CE at Nagoya University Hospital from January 2010 to May 2015...

AIMS AND BACKGROUND: Advanced endo-haemostatic technique performance and experience is extremely variable in distribution amongst pediatric endoscopists. Haemostatic spray (Hemospray®), a novel endo-haemostatic topically applied powder has the advantage of extreme ease of use and; hence may lower the threshold of competency required by the endoscopist thereby potentially reducing mortality. The aim of the study is to prospectively evaluate the efficacy and the safety of haemostatic spray in paediatric patients with AUGIB...

BACKGROUND AND AIMS: ERCP has the risk of exposure to ionizing radiation. Performers may unconsciously increase fluoroscopy time (FT) due to lack of radiation protection awareness. This study investigates whether a flashing warning light adopted as a behavioral intervention for performers reduces FT and radiation exposure during ERCP. METHODS: We conducted a prospective randomized trial of 200 therapeutic ERCPs. A flashing warning light was placed on top of the endoscopy monitor...

The innovative vascular unloading technology (VUT) allows continuous noninvasive arterial blood pressure (AP) monitoring. We aimed to investigate whether the VUT enables AP changes to be detected earlier compared with intermittent AP monitoring in patients undergoing gastrointestinal endoscopy. In this prospective observational study, we recorded continuous AP measurements with the VUT (CNAP system; CNSystems Medizintechnik AG, Graz, Austria) and intermittent AP measurements with upper arm cuff oscillometry in 90 patients undergoing complex gastrointestinal endoscopy (Department of Interventional Endoscopy at the University Medical Center Hamburg-Eppendorf, Hamburg, Germany)...

Biliary stent placement is an adjunct for complex biliary intervention. Patients with benign biliary strictures or aversion to external drainage may benefit from placement of retrievable biliary stents. This report describes a patient with a working diagnosis of benign biliary stricture who underwent interventional radiology-operated endoscopy-guided transnasal placement of a fully covered retrievable biliary stent.

Enteral access is one of the most common procedures performed in abdominal and interventional radiology. The surgical anatomy of the postoperative stomach may, however, make enteral access challenging. This report describes a patient with a pancreaticoduodenectomy complicated by a gastrojejunostomy leak who underwent 2 unsuccessful transoral endoscopic nasojejunal tube placements and 2 failed percutaneous gastrojejunostomy tube placements. Eventually, a gastrojejunostomy tube was placed utilizing percutaneous techniques with fluoroscopy assistance and gastrojejunoscopy guidance...

Biliary interventions are commonplace in interventional radiology. Occasionally, an anastomotic occlusion is encountered that cannot be traversed with fluoroscopy alone. Endoscopy is a tool that should be added to the interventional radiology armamentarium. Unfortunately, most departments do not have endoscopes regularly available for use by nonendoscopists. The disposable single-use flexible LithoVue scope has the potential to provide many applications for interventional radiologists. It is relatively low cost and is easy to use with a simple setup for novice endoscopists...

A 41-year-old man from the state of Chhattisgarh, India, had a previous history of nasopharyngeal rhinosporidosis for 27 years, for which he had surgical intervention seven times, most recently endoscopically 2 months earlier. For the last 8 months, he had noticed skin lesions on the shoulders and forehead. Of interest was a history of bathing in ponds as a child. Examination revealed a soft, skin-colored, strawberry-shaped papule on the forehead (Figure 1A), a papule with a hemorrhagic crust on the left shoulder (Figure 1B), and a crusted friable plaque on the right shoulder (Figure 1C)...
