Rings, webs, and diverticula are among the most common anatomic anomalies of the esophagus. Although these structural lesions are often asymptomatic, patients can develop significant problems with dysphagia, regurgitation, and aspiration. This article discusses the epidemiology, pathogenesis, diagnosis, and therapy of esophageal rings, webs, and diverticula with emphasis on the clinical, diagnostic, and therapeutic strategies involved in caring for patients with these conditions.

Prepyloric gastric antral muscular ring in an infant.
Clin J Gastroenterol
October 2024
Department of Diagnostic Radiology, Stony Brook University Hospital, Stony Brook, NY, USA.
Article Synopsis
- The text discusses a rare case of a prepyloric gastric muscular ring, which differs from the more commonly documented gastric webs, highlighting a lack of literature on this condition.
- It notes that most known gastric outlet obstructions in neonates are attributed to pyloric stenosis, leading to a limited consideration of other conditions like muscular rings.
- The authors suggest that the term "gastric ring" should specify the muscular nature to avoid confusion with submucosal or mucosal types in medical discussions.
Esophageal Granular Cell Tumor: An Uncommon Cause of Dysphagia.

Pathology, Orlando Veterans Affairs Medical Center, Orlando, USA.
Granular cell tumors (GCTs) are rare, typically benign, solitary neoplasms that can arise throughout the body, with reports of cases in the tongue, esophagus, colon, skin, vulva, and skeletal muscle, among others. Although GCTs are usually asymptomatic, esophageal GCTs can grow large enough to cause dysphagia. When developing the differential diagnosis for dysphagia, a broad consideration includes routine etiologies such as esophageal strictures, eosinophilic esophagitis, carcinoma, webs and rings, achalasia, and motility disorders, but GCTs may not readily come to mind.

Center for Devices and Radiological Health, United States Food and Drug Administration, Silver Spring, Maryland.
Purpose: To develop a questionnaire with standardized questions and images about visual symptoms and satisfaction administered before and after cataract surgery with monofocal and various (premium) intraocular lenses (IOLs).
Design: A prospective, observational study of cataract surgery patients completing a self-administered questionnaire preoperatively and postoperatively at 4 to 6 months.
Participants: Five hundred fifty-four patients with plans to undergo implantation of the same IOL in both eyes on separate occasions in 20 ophthalmology practices.
Development of a Patient-Reported Outcome Measure to Assess Symptoms Associated with Cataract Surgery and Intraocular Lens Implants.
Ophthalmology
July 2023
Department of Ophthalmology, University of California, Los Angeles, California.
Purpose: To develop a standardized patient-reported outcome measure of visual perceptions and symptoms for implanted premium and monofocal intraocular lenses (IOLs).
Design: Observational study before and after IOL implants to assess the measure and symptom experience.
Participants: Adults scheduled for binocular implantation of the same IOL type completed the survey at baseline prior to surgery (n = 716) and postoperatively (n = 554).
