Increased Risk of Progression to Gastric Adenocarcinoma in Patients with Non-dysplastic Gastric Intestinal Metaplasia Versus a Control Population.

Aim: In previous studies, the 5-year progression rate of gastric intestinal metaplasia to gastric adenocarcinoma has varied substantially. We investigated the incidence rate of dysplasia and gastric adenocarcinoma and the rate of progression among a cohort of patients with non-dysplastic gastric intestinal metaplasia.

Methods: This is a single-center, single-cohort retrospective study.

Appendiceal Adenocarcinoma Presenting as a Rectal Polyp.

Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively.

Abdominal compression during endoscopy (the Bolster technique) demonstrates hidden Schatzki rings (with videos).

Background And Aims: Schatzki rings are found in the distal esophagus, are associated with hiatal hernias, and present with intermittent dysphagia to solid foods. They can be identified by radiology (GI series or barium swallow studies) or endoscopy. Rings are not always visualized during endoscopy in patients in whom they are suspected clinically.

Obliteration of symptomatic Schatzki rings with jumbo biopsy forceps (with video).

A Schatzki ring is a submucosal, fibrotic thickening located at the gastroesophageal junction. Endoscopic treatment traditionally involves disruption of the ring. Many approaches have been described including bougies, balloons, biopsies, and diathermic monopolar incision.
