Objective: Symptomatic lower esophageal (Schatzki) rings are one of the most common causes of dysphagia and esophageal food impaction. Although these rings are often diagnosed fluoroscopically, patients are typically referred for dilation procedures performed by a gastroenterologist. Because these procedures are invasive and carry risks, including esophageal perforation, an alternative treatment option is needed. Read More

Gastrointest Endosc 2016 May 10;83(5):1024-6. Epub 2015 Nov 10.

Tufts Medical Center, Boston, Massachusetts, USA.

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. Read More

Vestn Rentgenol Radiol 2015 Jan-Feb(1):5-15

Objective: To determine the importance of a symptom of Schatzki ring.

Material And Methods: The results of examining 95 patients aged 62-92 years with the symptoms of dyspepsia in the Netanya State Geriatric Center (Israel) in 1994-2004 were analyzed. Standard X-ray study of the upper digestive tract was complemented by provocation tests. Read More

Aim: To determine if esophageal capsule endoscopy (ECE) is an adequate diagnostic alternative to esophagogastroduodenoscopy (EGD) in pre-bariatric surgery patients.

Methods: We conducted a prospective pilot study to assess the diagnostic accuracy of ECE (PillCam ESO2, Given Imaging) vs conventional EGD in pre-bariatric surgery patients. Patients who were scheduled for bariatric surgery and referred for pre-operative EGD were prospectively enrolled. Read More

Department of Radiology, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave., ML 5031, Cincinnati, OH 45229, USA.

Background: A Schatzki ring (SR) is an uncommon finding in children. Entities previously associated with an SR include gastroesophageal reflux (GER), hiatal hernia (HH) and eosinophilic esophagitis (EE).

Objective: The purpose of this study was to evaluate the overall incidence of SR and the frequency of the different entities associated with SR in the pediatric population. Read More

Department of Gastroenterology, German Clinic for Diagnostics Wiesbaden, 65191 Wiesbaden, Germany.

Aim: To study, whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.

Methods: From 1987 until 2007, all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed. All of them underwent structured interviews with regards to clinical symptoms, as well as endoscopic and/or radiographic examinations. Read More

J Pediatr Gastroenterol Nutr 2004 Apr;38(4):436-41

Division of Gastroenterology, Children's Hospital Boston, and Department of Pediatrics, Harvard Medical School, Massachusetts, 02115, USA.

Objective: To describe the clinicopathologic characteristics of children with Schatzki ring and to determine if Schatzki ring is associated with eosinophilic esophagitis.

Methods: The authors report 18 adolescents with radiographically diagnosed Schatzki ring (SR). Their clinical and histologic characteristics were reviewed in a blinded fashion. Read More

Department of Radiology, Children's Hospital, Harvard Medical School, 300 Longwood Avenue, Boston, MA 02115, USA.

Background: The Schatzki ring is a well-known clinical and radiologic entity in adults, but is thought to be rare in childhood. Objective. To review the clinical presentations and radiologic findings of children and young adults with Schatzki rings. Read More

Schatzki first reported a ring-like structure at the esophagogastric mucosal junction in 1953. There is still no uniform agreement as to its exact location, etiology, or clinical importance. We found an esophagogastric ring in 15% to 18% of 22,368 patients having routine upper gastrointestinal examinations. Read More

This study investigates the effect of a single dilation on the morphology of the lower esophageal ring and on the clinical course of symptomatic patients. Thirty-three patients were studied prospectively for a mean period of 24.3 +/- 19. Read More

Department of Internal Medicine, Ochsner Clinic, New Orleans, Louisiana.

We report a case of esophageal perforation that occurred in a man with a known symptomatic Schatzki ring. It is possible that the perforation may have been avoided with therapy of the lower esophageal ring. The evaluation and management of esophageal perforation are discussed. Read More

A case report of a patient with Schatzki's ring which was fibrous and stenotic is presented. The treatment with a new surgical technique with good results is discussed. Read More

Most patients with Schatzki's ring have dysphagia that can be relieved by esophageal dilation. We report an unusual case in which dysphagia caused by a Schatzki ring could not be managed conservatively. The obstructing ring was excised through a gastrotomy approached by a left-sided thoracotomy. Read More

Am J Surg 1980 Apr;139(4):591-4

Thirty-six patients with symptomatic Schatzki rings were treated by rupture of the ring and repair and followed up an average of 6 years. Thirteen (37 percent) had no recurrence of symptoms; 8 (23 percent) had recurrence of mild symtpoms; 14 (40 percent) had recurrence of symptoms as severe as those experienced preoperatively. Failure was associated with recurrence of the ring and hernia in some. Read More

A patient is described who suffered from prolapse of the lower oesophageal mucosa in the presence of a Schatzki ring. There was variable dysphagia culminating in total aphagia. The clinical symptoms disappeared without any treatment once the patient had overcome several years of psychological stress. Read More

Manometric features were correlated with roentgen configurations of the esophagogastric region in subjects with hiatal hernias and with rings by simultaneous cineradiographic and manometric study. The supradiaphragmatic pouch in small hiatal hernias was shown to have two functionally distinct components. Its upper portion (vestibule) had sequential contractile motor activity in response to swallowing. Read More
