Background/Aims Multiple rapid swallows (MRS) is a provocative test during high-resolution esophageal manometry (HRM) to evaluate contraction reserve (CR). This study aims to determine the prevalence of CR in patients with ineffective esophageal motility (IEM) and MRS performed in the upright position, and to assess the ideal number of MRS sequence...

Background and aim: Although fidaxomicin is an effective first-line treatment for Clostridioides difficile infection, it has not been well studied in patients with inflammatory bowel disease. We aimed to assess the effectiveness of fidaxomicin for the treatment of C. difficile infection in patients with inflammatory bowel disease. Methods: This...

Background: The number of bottles of esophageal biopsies needed for the evaluation of eosinophilic esophagitis (EoE) is unclear, despite cost differences. Aims: Assess the clinical outcomes between patients with one and two bottles of esophageal biopsies for the assessment of EoE. Methods: Retrospective study of adults who underwent esophagoga...

Objectives Patients with microscopic colitis may have subtle macroscopic findings on colonoscopy such as erythema, edema, or altered vascular pattern; however, radiographic abnormalities on cross-sectional imaging have not been investigated. We aimed at identifying the abdominopelvic radiographic abnormalities in patients with microscopic colitis,...

Introduction and objectives: The goal of this study was to assess lifestyle habits and physician counseling of patients with hereditary hemochromatosis (HH), and determine the prevalence of direct-to-consumer (DTC) genetic testing.

Malnutrition is prevalent in cirrhosis. Vitamin and mineral deficiencies, including vitamin D, vitamin A, and zinc, are common and have been shown to correlate with survival. Our aim was to review the mechanisms of vitamin D, vitamin A, and zinc deficiencies in cirrhosis and the clinical assessment of affected patients, their outcomes based on the...

Background and aims: Incision of the cricopharyngeal (CP) muscle with flexible endoscopy is an important approach for Zenker diverticulum (ZD) repair with symptomatic resolution in approximately 90% of cases, but recurrence has been reported in up to 20%. We report our experience with a new endoscopic myectomy of the CP muscle and compare the outc...
