Hemospray® (hemostatic powder TC-325) as monotherapy for acute gastrointestinal bleeding: a multicenter prospective study.

Background: Hemostatic powders are used as second-line treatment in acute gastrointestinal (GI) bleeding (AGIB). Increasing evidence supports the use of TC-325 as monotherapy in specific scenarios. This prospective, multicenter study evaluated the performance of TC-325 as monotherapy for AGIB.

Hemostatic powder TC-325 treatment of malignancy-related upper gastrointestinal bleeds: International registry outcomes.

Background And Aim: Upper gastrointestinal tumors account for 5% of upper gastrointestinal bleeds. These patients are challenging to treat due to the diffuse nature of the neoplastic bleeding lesions, high rebleeding rates, and significant transfusion requirements. TC-325 (Cook Medical, North Carolina, USA) is a hemostatic powder for gastrointestinal bleeding.

Outcomes of Hemospray therapy in the treatment of intraprocedural upper gastrointestinal bleeding post-endoscopic therapy.

Introduction: With increasing advances in minimally invasive endoscopic therapies and endoscopic resection techniques for luminal disease, there is an increased risk of post-procedure bleeding. This can contribute to significant burden on patient's quality of life and health resources when reintervention is required. Hemospray (Cook Medical, North Carolina, USA) is a novel haemostatic powder licensed for gastrointestinal bleeding.

Quality indicators for Barrett's endotherapy (QBET): UK consensus statements for patients undergoing endoscopic therapy for Barrett's neoplasia.

Introduction: Endoscopic therapy for the management of patients with Barrett's oesophagus (BE) neoplasia has significantly developed in the past decade; however, significant variation in clinical practice exists. The aim of this project was to develop expert physician-lead quality indicators (QIs) for Barrett's endoscopic therapy.

Methods: The RAND/UCLA Appropriateness Method was used to combine the best available scientific evidence with the collective judgement of experts to develop quality indicators for Barrett's endotherapy in four subgroups: pre-endoscopy, intraprocedure (resection and ablation) and postendoscopy.

Hemostatic spray powder TC-325 in the primary endoscopic treatment of peptic ulcer-related bleeding: multicenter international registry.

Background: Upper gastrointestinal bleeding (UGIB) is a leading cause of morbidity and is associated with a 2 % - 17 % mortality rate in the UK and USA. Bleeding peptic ulcers account for 50 % of UGIB cases. Endoscopic intervention in a timely manner can improve outcomes.

Outcomes from an international multicenter registry of patients with acute gastrointestinal bleeding undergoing endoscopic treatment with Hemospray.

Background And Aim: Acute gastrointestinal bleeding carries poor outcomes unless prompt endoscopic hemostasis is achieved. Mortality in these patients remains significant. Hemospray is a novel intervention that creates a mechanical barrier over bleeding sites.

A prospective audit of the efficacy, safety, and acceptability of low-volume polyethylene glycol (2 L) versus standard volume polyethylene glycol (4 L) versus magnesium citrate plus stimulant laxative as bowel preparation for colonoscopy.

Background: High-quality video colonoscopy requires adequate preparation of the bowel to ensure both adequate procedure completion rates and polyp detection rates. We sought to examine our practice to determine which bowel preparation cleansed most effectively in our patients.

Aim: A prospective audit of the efficacy, safety, and acceptability of low-volume polyethylene glycol (2-L Moviprep; Norgine Pharmaceuticals) versus standard volume polyethylene glycol (4-L KleanPrep; Norgine Pharmaceuticals) versus magnesium citrate (Citramag; Sanochemia UK Ltd.

Respiratory and laryngeal symptoms secondary to gastro-oesophageal reflux.

Gastro-oesophageal reflux may cause a range of laryngeal and respiratory symptoms. Mechanisms responsible include the proximal migration of gastric refluxate beyond the upper oesophageal sphincter causing direct irritation of the larynx and lower airway. Alternatively, refluxate entering the distal oesophagus alone may stimulate oesophageal sensory nerves and indirectly activate airway reflexes such as cough and bronchospasm.

Impact of nutritional factors on survival in patients with inoperable oesophageal cancer undergoing self-expanding metal stent insertion.

Background: Undernutrition has been shown to be predictive of 30-day mortality in patients undergoing self-expanding metal stent (SEMS) insertion for inoperable oesophageal cancer. The aim of this study was to assess the relationship between nutritional factors and 30-day mortality in patients undergoing SEMS insertion for palliation of oesophageal cancer.

Methods: A retrospective cohort study was conducted from April 2007 to June 2009.

Self-expanding metal stent insertion for inoperable esophageal carcinoma in Belfast: an audit of outcomes and literature review.

Successful palliation of dysphagia in patients with inoperable esophageal carcinoma has a major effect on quality of life. Self-expanding metal stents (SEMS) are currently recommended for rapid symptomatic relief when life expectancy is less than 3 months. We assessed complication and reintervention rates along with survival outcomes in patients with inoperable esophageal carcinoma undergoing stent insertion.

Nicorandil associated colonic ulceration: case series of an increasingly recognized complication.

Background: Nicorandil is widely accepted in the therapeutic armamentarium of ischemic heart disease and, although nicorandil-induced oral and anal ulcerations have been established in the literature, only five cases have reported the possibility of nicorandil-induced ulceration elsewhere in the gastrointestinal tract. There have been recent case reports which have suggested the possible causative association between nicorandil and colonic ulceration, either in isolation or in combination with anal ulceration.

Methods: We report a case series of eight patients prescribed with nicorandil therapy presenting with gastrointestinal symptoms and subsequently diagnosed with colonic ulceration on colonoscopy.

High resolution manometry and multichannel intraluminal impedance oesophageal manometry in clinical practice.

The past decade has seen new technological advances in the investigation of oesophageal motility disorders. Multichannel intraluminal impedance monitoring has been used as an adjunct to conventional manometry in the assessment of oesophageal function, independent of radiography. High resolution manometry provides additional information over conventional manometry, and its topographic analysis makes interpretation of studies easier.

Nonacid reflux episodes reaching the pharynx are important factors associated with cough.

Background: Gastroesophageal reflux is implicated in the pathogenesis of asthma and chronic cough. To date most studies have focused on acid reflux measured by pH below the upper esophageal sphincter (UES). The aim of this study was to assess the relationship between cough and reflux through the UES into the pharynx.
