Hemospray as first-line treatment option for malignant gastrointestinal bleeding: A cost-utility analysis in the United Kingdom.

Aims: For managing malignant upper gastrointestinal bleeding (MUGIB), randomised control trial data have shown the haemostatic powder; Hemospray (TC-325), results in greater immediate haemostasis and lower 30-day rebleeding rates than standard endoscopic therapy (SET). We sought to determine if using TC-325 as a first-line option for patients with MUGIB would be cost-effective compared with SET in the United Kingdom.

Methods: A decision tree was developed among patients with MUGIB, assessing initial therapy with TC-325 or SET over a 30-day time horizon.

Efficacy and Safety of Cryoablation in Barrett's Esophagus and Comparison with Radiofrequency Ablation: A Meta-Analysis.

Background: The mainstay approach in endoscopic eradication therapy (EET) for dysplastic Barrett's esophagus (BE) includes the endoscopic resection of visible lesions, accompanied by ablation of the residual metaplastic epithelium. Cryoablation therapy is one such emerging ablation technique in this field. This systematic review with a meta-analysis aims to accumulate pooled data on cryoablation performance in the treatment of patients with BE and to compare this technique to the standard of care radiofrequency ablation (RFA).

Evaluating no fixation, endoscopic suture fixation, and an over-the-scope clip for anchoring fully covered self-expanding metal stents in benign upper gastrointestinal conditions: a comparative multicenter international study (With Video).

Background And Aims: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Stentfix {SF], Ovesco Endoscopy) for stent anchoring has recently been developed. The aim of this study was to evaluate the effect of OTSC fixation on FCSEMS migration rate.

Endoscopic suturing and clipping devices for defects in the GI tract.

Gastrointestinal luminal defects, including perforations, leaks and fistulae, pose persistent obstacles in endoscopic therapeutic interventions. A variety of endoscopic approaches have been proposed, with through-the-scope clipping (TTSC), over-the-scope clipping (OTSC) and suturing representing the main techniques of tissue apposition. However, the heterogeneity in defect morphology, the technical particularities of different locations in the gastrointestinal (GI) tract and the impact of various parameters on the final outcome, do not allow distinct conclusions and recommendations on the optimal approaches for defect closure, and, thus, current practice is based on endoscopists experience and local availability of devices.

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.

The endoscopic management of oesophageal strictures.

An oesophageal stricture refers to a narrowing of the oesophageal lumen, which may be benign or malignant. The cardinal feature is dysphagia, and this may result from intrinsic oesophageal disease or extrinsic compression. Oesophageal strictures can be further classified as simple or complex depending on stricture length, location, diameter, and underlying aetiology.

Risk of metastasis among patients diagnosed with high-risk T1 esophageal adenocarcinoma who underwent endoscopic follow-up.

Esophagectomy and lymphadenectomy have been the standard of care for patients at high risk (HR) of lymph node metastasis following a diagnosis of early esophageal adenocarcinoma (OAC) after endoscopic resection (ER). However, recent cohorts suggest lymph node metastasis risk is lower than initially estimated, suggesting organ preservation with close endoscopic follow-up is a viable option. We report on the 3- and 5-year risk of lymph node/distant metastasis among patients diagnosed with early HR-T1 OAC undergoing endoscopic follow-up.

Peroral endoscopic myotomy for the management of symptomatic cricopharyngeal bar (C-POEM): a case series and video demonstration.

Background: A cricopharyngeal bar refers to a radiological description of a prominent cricopharyngeal muscle. While these may be incidental, they can lead to significant oropharyngeal dysphagia due to incoordination of the upper esophageal sphincter and true luminal narrowing. Various treatments have been used for the management of cricopharyngeal bar, including botulinum toxin injection, dilation, and surgical myotomy.

Endoscopic Management of Dysplastic Barrett's Oesophagus and Early Oesophageal Adenocarcinoma.

Barrett's oesophagus is a pathological condition whereby the normal oesophageal squamous mucosa is replaced by specialised, intestinal-type metaplasia, which is strongly linked to chronic gastro-oesophageal reflux. A correct endoscopic and histological diagnosis is pivotal in the management of Barrett's oesophagus to identify patients who are at high risk of progression to neoplasia. The presence and grade of dysplasia and the characteristics of visible lesions within the mucosa of Barrett's oesophagus are both important to guide the most appropriate endoscopic therapy.

Metabolic and Bariatric Endoscopy: A Mini-Review.

We are currently in a worldwide obesity pandemic, which is one of the most significant health problems of the 21st century. As the prevalence of obesity continues to rise, new and innovate treatments are becoming available.

Success rates of fixation techniques on prevention of esophageal stent migration: a systematic review and meta-analysis.

Background:  Esophageal stenting is an important intervention for managing malignant and benign dysphagia, with stent migration representing a common drawback. This systematic review with meta-analysis aimed to assess the benefit of stent fixation over nonfixation.

Methods:  A systematic search was performed in MEDLINE, Cochrane, Scopus, and ClinicalTrials.

Minimally invasive endoscopic therapies for gastro-oesophageal reflux disease.

The prevalence of the gastro-oesophageal reflux disease (GORD) in the western world is increasing. Uncontrolled GORD can lead to harmful long-term sequela such as oesophagitis, stricture formation, Barrett's oesophagus and oesophageal adenocarcinoma. Moreover, GORD has been shown to negatively impact quality of life.

Effect of gastro-esophageal reflux symptoms on the risk of Barrett's esophagus: A systematic review and meta-analysis.

Background And Aim: Gastro-esophageal reflux (GER) is the main predisposing factor for Barrett's esophagus (BE). A more precise estimate of the association of GER symptoms with the risk of BE would be important to prioritize endoscopic screening. We conducted a systematic review and meta-analysis to examine this issue.

The natural history of low-grade dysplasia in Barrett's esophagus and risk factors for progression.

Background And Aim: Barrett's esophagus is associated with increased risk of esophageal adenocarcinoma. The optimal management of low-grade dysplasia arising in Barrett's esophagus remains controversial. We performed a retrospective study from a tertiary referral center for Barrett's esophagus neoplasia, to estimate time to progression to high-grade dysplasia/esophageal adenocarcinoma in patients with confirmed low-grade dysplasia compared with those with downstaged low-grade dysplasia from index presentation and referral.

Applications of Artificial Intelligence for the Diagnosis of Gastrointestinal Diseases.

The development of convolutional neural networks has achieved impressive advances of machine learning in recent years, leading to an increasing use of artificial intelligence (AI) in the field of gastrointestinal (GI) diseases. AI networks have been trained to differentiate benign from malignant lesions, analyze endoscopic and radiological GI images, and assess histological diagnoses, obtaining excellent results and high overall diagnostic accuracy. Nevertheless, there data are lacking on side effects of AI in the gastroenterology field, and high-quality studies comparing the performance of AI networks to health care professionals are still limited.

Bariatric and Metabolic Endoscopy: A New Paradigm.

The prevalence of obesity, type 2 diabetes mellitus, and metabolic syndromes is increasing globally. Minimally invasive metabobariatric (MB) endoscopic therapies are adjunct treatments that can potentially bridge the gap between surgical interventions and medical therapy. A growing number of MB techniques are becoming available, allowing for more personalized and patient-targeted treatment options for specific disease states.

Side effects of long-term use of proton pump inhibitors: practical considerations.

Proton pump inhibitors (PPIs) are among the most commonly prescribed drugs due to the increasing incidence of acid‑related disorders, but a large number of prescriptions are issued with inappropriate indications. Despite PPIs being effective and well tolerated, there have been growing concerns about potential adverse effects associated with long‑term use of these drugs. Indeed, pharmacovigilance agencies have issued broad-based product warnings on the association between treatment with PPIs and long‑term complications, including increased risk of fractures and impaired magnesium absorption.

Systematic review with meta-analysis: risk factors for Barrett's oesophagus in individuals with gastro-oesophageal reflux symptoms.

Background: Gastro-oesophageal reflux is considered the main risk factor for Barrett's oesophagus. The role of other potential risk factors for the development of Barrett's oesophagus in patients with gastro-oesophageal reflux symptoms is controversial.

Aims: To perform a systematic review and meta-analysis examining risk factors in development of Barrett's oesophagus.

New Devices for Endoscopic Treatments in Gastroenterology: A Narrative Review.

Endoscopy is in a period of continuous innovations in terms of image quality, endoscopes, post-processing software and lastly, application of Artificial Intelligence. Therapeutic boundaries have expanded, widening the grey zone between endoscopy and surgery, and increasing endoscopic approaches in clinical scenarios where, until a few years ago, surgery was the only option. New scopes and accessories have made it easier to access critical areas such as the biliary tree and the small bowel intestine.

Gastric cancer prevention strategies: A global perspective.

Gastric cancer (GC) is the fifth most common cancer worldwide, and mortality rates are still high. Primary preventive strategies, aimed to reduce risk factors and promote protective ones, will lead to a decrease in GC incidence. Helicobacter pylori infection is a well-established carcinogen for GC, and its eradication is recommended as the best strategy for the primary prevention.
