Summary
Cricopharyngeal bars (CPB) are often incidental findings during swallowing exams. Severe CPBs may relate to dysphagia, with treatments including myotomy or endoscopic procedures.
Area of Science:
- Otolaryngology
- Gastroenterology
- Swallowing Disorders
Background:
- Cricopharyngeal bar (CPB) is a posterior indentation at the pharyngoesophageal junction.
- CPB is identified during a Video Fluoroscopic Swallowing Exam (VFSE), also known as a modified barium swallow.
- The impact of CPBs on swallowing function remains a subject of ongoing discussion.
Purpose of the Study:
- To review the appearance, effects, and therapeutic interventions for cricopharyngeal bars (CPBs).
Main Methods:
- A systematic literature review was conducted using PubMed.
- The research focused on studies detailing the characteristics and management of CPBs.
Main Results:
- CPBs are frequently diagnosed during VFSE, often in patients presenting with dysphagia.
- However, CPBs can also be present in individuals without dysphagia, indicating they are not always causative.
- The severity of the protrusion and the condition of the inferior pharyngeal constrictor muscle may influence the effect of CPBs on swallowing.
Conclusions:
- CPBs often appear as incidental findings during modified barium swallow examinations.
- A definitive link to dysphagia is typically associated only with severe cases of CPB.
- Treatment options for symptomatic CPBs include cricopharyngeal myotomy or endoscopic interventions like bougie or balloon dilation.

Upper GI Series: Barium Swallow
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Pharynx
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
