Neoplastic Progression Risk in Females With Barrett's Esophagus: A Systematic Review and Meta-Analysis of Individual Patient Data.

Background And Aims: Females with Barrett's esophagus (BE) have a lower risk of neoplastic progression than males, but sufficiently powered risk analyses are lacking. This systematic review and meta-analysis of individual patient data (IPD) aimed to provide more robust evidence on neoplastic progression risk in females.

Methods: We conducted a systematic literature search of 3 electronic databases (Medline, Embase, Google Scholar) from inception until August 2023.

Endoscopic resection in subepithelial lesions of the upper gastrointestinal tract: Experience at a tertiary referral hospital in The Netherlands.

Histological confirmation of subepithelial lesions (SELs) in the upper gastrointestinal tract remains challenging. Endoscopic resection of SELs is increasingly used for its excellent diagnostic yield and opportunity to do away with continued surveillance. In this study, we aimed to evaluate the indications, success rates and complications of different endoscopic resection techniques for SELs at a large, tertiary referral hospital in Rotterdam, The Netherlands.

Large- and medium-sized arterial aneurysms in two patients with SMAD4-related juvenile polyposis syndrome.

Germline SMAD4 pathogenic variants (PVs) cause juvenile polyposis syndrome (JPS), which is known for an increased risk of gastrointestinal juvenile polyps and gastrointestinal cancer. Many patients with SMAD4 PV also show signs of hereditary hemorrhagic telangiectasia (HHT) and some patients have aneurysms and dissections of the thoracic aorta. Here we describe two patients with a germline SMAD4 PV and a remarkable clinical presentation including multiple medium-sized arterial aneurysms.

Curative criteria for endoscopic treatment of oesophageal adenocarcinoma.

The incidence of oesophageal adenocarcinoma has been increasing rapidly in the Western world. A well-known risk factor for developing this type of tumour is reflux disease, which can cause metaplasia from the squamous cell mucosa to columnar epithelium (Barrett's Oesophagus) which can progress to dysplasia and eventually adenocarcinoma. With the rise of the incidence of oesophageal adenocarcinoma, research on the best way to manage this disease is of great importance and has changed treatment modalities over the last decades.

Endoscopic resection for residual oesophageal neoplasia after definitive chemoradiotherapy.

Definitive chemoradiation is the recommended treatment for locally advanced, irresectable oesophageal cancer and a valid alternative to neoadjuvant chemoradiotherapy (CRT) with surgery in oesophageal squamous cell cancer (OSCC) patients. In case of locoregional recurrence, salvage treatment can be considered in fit and resectable patients. Salvage surgery is a valid option but associated with significant morbidity.

Performance of a single-use gastroscope for esophagogastroduodenoscopy: Prospective evaluation.

Reprocessing reusable endoscopes is challenging due to their non-sterilizable nature. Disinfection has been shown to have a significant risk of failure with serious consequences. Single-use endoscopes can eliminate contamination risk and reduce workflow delays caused by reprocessing.

Incidence and Prediction of Unrelated Mortality After Successful Endoscopic Eradication Therapy for Barrett's Neoplasia.

Background & Aims: Follow-up (FU) strategies after endoscopic eradication therapy (EET) for Barrett's neoplasia do not consider the risk of mortality from causes other than esophageal adenocarcinoma (EAC). We aimed to evaluate this risk during long-term FU, and to assess whether the Charlson Comorbidity Index (CCI) can predict mortality.

Methods: We included all patients with successful EET from the nationwide Barrett registry in the Netherlands.

Endoscopic submucosal dissection for early esophageal squamous cell carcinoma: long-term results from a Western cohort.

Background: Although endoscopic submucosal dissection (ESD) is established as first-choice treatment for early esophageal squamous cell carcinoma (ESCC) worldwide, most data are derived from Asian studies. We aimed to evaluate the long-term outcomes of ESD for patients with early ESCC in a Western cohort.

Methods: In this retrospective cohort study, patients with early ESCC amenable to ESD were included from four tertiary referral hospitals in the Netherlands between 2012 and 2017.

Predicting procedure duration of colorectal endoscopic submucosal dissection at Western endoscopy centers.

Overcoming logistical obstacles for the implementation of colorectal endoscopic submucosal dissection (ESD) requires accurate prediction of procedure times. We aimed to evaluate existing and new prediction models for ESD duration. Records of all consecutive patients who underwent single, non-hybrid colorectal ESDs before 2020 at three Dutch centers were reviewed.

Western outcomes of circumferential endoscopic submucosal dissection for early esophageal squamous cell carcinoma.

Background And Aims: Circumferential endoscopic submucosal dissection (cESD) in the esophagus has been reported to be feasible in small Eastern case series. We assessed the outcomes of cESD in the treatment of early esophageal squamous cell carcinoma (ESCC) in Western countries.

Methods: We conducted an international study at 25 referral centers in Europe and Australia using prospective databases.

Outcome of Completion Surgery after Endoscopic Submucosal Dissection in Early-Stage Colorectal Cancer Patients.

T1 colorectal cancers (T1CRC) are increasingly being treated by endoscopic submucosal dissection (ESD). After ESD of a T1CRC, completion surgery is indicated in a subgroup of patients. Currently, the influence of ESD on surgical morbidity and mortality is unknown.

Impact of ERCP simulator training on early ERCP learning curves of novice trainees: a cohort study.

Simulator-based training has been extensively studied in training gastroduodenoscopy and colonoscopy and shown to significantly improve learning curves of novices. Data on simulator-based training in endoscopic retrograde cholangiopancreatography (ERCP) are scarce. We aimed to determine the impact of 2-day intensive hands-on simulator training on the course of the learning curve of novice trainees.

Increased risk of esophageal squamous cell carcinoma in patients with squamous dysplasia: a nationwide cohort study in the Netherlands.

Squamous dysplasia is the histological precursor of esophageal squamous cell carcinoma (ESCC). The optimal management for distinct squamous dysplasia grades remains unclear because the corresponding risk of developing ESCC is unknown. We aimed to assess the ESCC risk in patients with esophageal squamous dysplasia in a Western country.

Endoscopic screening of the upper gastrointestinal tract for second primary tumors in patients with head and neck cancer in a Western country.

Background: Patients with head and neck squamous cell carcinoma (HNSCC) can develop second primary tumors (SPTs) in the esophagus. Endoscopic screening could lead to detection of SPTs at early stages and improve survival.

Methods: We performed a prospective endoscopic screening study in patients with curably treated HNSCC diagnosed between January 2017-July 2021 in a Western country.

Endoscopic resection of upper gastrointestinal lesions using the colonic Ovesco full-thickness resection device: Retrospective observational case series of 22 cases.

 The endoscopic full-thickness resection (EFRT) device (FTRD) has been shown to have acceptable outcomes in regard to efficacy and safety in the resection of colorectal lesions. Data on its use in the upper gastrointestinal tract are limited to small case series.  All consecutive patients undergoing endoscopic full-thickness resection of gastric or duodenal lesions at our institutions were analyzed retrospectively for a primary endpoint of technical success.

Clinical Relevance of Random Biopsies From the Esophagogastric Junction After Complete Eradication of Barrett's Esophagus is Low.

Background & Aims: Although random histological sampling from the esophagogastric junction (EGJ) after complete eradication of Barrett's esophagus (BE) is recommended, its clinical relevance is questionable. This study aimed to assess the incidence and long-term outcomes of findings from random EGJ biopsies in a nationwide cohort with long-term follow-up.

Methods: We included all patients with successful endoscopic eradication therapy (EET), defined as complete endoscopic eradication of all visible BE (CE-BE), for early BE neoplasia from the Dutch registry.
