Am J Gastroenterol 2021 Apr;116(4):675-682

1Department of Gastroenterology & Hepatology, Amsterdam University Medical Centers, location Academic Medical Center, Amsterdam, the Netherlands; 2Cernostics, Pittsburgh, Pennsylvania, USA; 3Department of Gastroenterology & Hepatology, Amsterdam University Medical Centers, location VUmc, Amsterdam, the Netherlands; 4Department of Pathology, University Medical Center, Utrecht, the Netherlands; 5Department of Pathology, Pathology DNA-BV, St. Antonius Hospital, Nieuwegein, the Netherlands; 6Department of Pathology, Amsterdam University Medical Centers, location Academic Medical Center, Amsterdam, the Netherlands.

Introduction: Low-grade dysplasia (LGD) is the best predictor of neoplastic progression in Barrett's esophagus (BE). Most LGD cases are downstaged to nondysplastic (ND) BE on expert pathologist review, which is prone to interobserver variation and not widely available. Recent studies indicate that a risk prediction assay (TissueCypher) risk stratifies patients with NDBE for neoplastic progression. Read More

Lumbar Spondylolisthesis Progression: What is the Effect of Lumbar Medial Branch Nerve Radiofrequency Ablation on Lumbar Spondylolisthesis Progression? A Single-Center, Observational Study.

J Pain Res 2021 3;14:1193-1200. Epub 2021 May 3.

Department of Anesthesiology, Emory University School of Medicine, Atlanta, GA, 30308, USA.

Background: Radiofrequency ablation (RFA) is a denervation therapy commonly performed for pain of facet etiology. Degenerative spondylolisthesis, a malalignment of the spinal vertebrae, may be a co-existing condition contributing to pain; yet the effect of RFA on advancing listhesis is unknown. To the extent that denervating RFA may weaken paraspinal muscles that provide stability to the spine, the therapy can potentially contribute to progressive spinal instability. Read More

New safe approach to target symptomatic Hisian ectopy/tachycardia.

Europace 2021 May 11. Epub 2021 May 11.

Department of Cardiology, Rouen University Hospital, 1 rue de Germont, 76031 Rouen Cedex, France.

Aims: Although cryoenergy safety profile is appropriate for the ablation of arrhythmogenic foci near the conduction system, mapping using the cryoablation catheter is of limited precision. Combining the safety of cryoenergy and the high precision of a 3D mapping system therefore appears the most appropriate set-up for ablation in the vicinity of the His bundle.

Methods And Results: A 29-year-old woman with a 3-year history of increasing shortness of breath and palpitations refractory to medical treatment was sent to the electrophysiology (EP) laboratory for catheter ablation. Read More

Extension of early esophageal squamous cell neoplasia into ducts and submucosal glands and the role of endoscopic ablation therapy.

Gastrointest Endosc 2021 May 8. Epub 2021 May 8.

Dept. of Gastroenterology and Hepatology, St. Antonius Hospital, Nieuwegein, the Netherlands;; Dept. of Gastroenterology and Hepatology, University Medical Center Utrecht, Utrecht University, Utrecht, the Netherlands;. Electronic address:

Background And Aims: Early esophageal squamous cell neoplasia (ESCN) is preferably treated with en-bloc endoscopic resection. Ablation might be an alternative for flat ESCN, but ESCN extension along the epithelial lining of ducts and submucosal glands (SMGs) might jeopardize ablation efficacy. Clinical studies suggest that local recurrence might arise from such buried ESCN niches after ablation. Read More
