Esophageal Achalasia

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

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-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...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube through...

Deglutition

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...

Upper GI Series: Barium Swallow

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...

Summary

This summary is machine-generated.

Oropharyngeal dysphagia (OD) affects over 50% of stroke survivors, leading to malnutrition and pneumonia. Repetitive transcranial magnetic stimulation (rTMS) shows promise in improving swallow function and aiding recovery in these patients.

Area of Science:

Neuroscience
Gastroenterology
Rehabilitation Medicine

Background:

Oropharyngeal dysphagia (OD) is a common, often underdiagnosed complication post-stroke, contributing to malnutrition and aspiration pneumonia (AP).
AP is a significant cause of mortality in acute stroke patients.
Current management focuses on compensatory strategies that do not address underlying swallowing physiology or neural recovery.

Purpose of the Study:

To evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in improving swallow physiology in stroke patients with dysphagia.
To explore the potential of neurostimulation to promote cortical neuroplasticity for swallowing recovery.

Main Methods:

The study assessed the impact of rTMS on dysphagic stroke patients.
Videofluoroscopy and/or fiberoptic endoscopy were used for instrumental assessment.
Neuroimaging techniques were employed to observe changes in pharyngeal motor cortical areas.

Main Results:

rTMS treatment resulted in significant improvements in swallow physiology.
Evidence of plastic changes in pharyngeal motor cortical areas relevant to swallowing was observed.
Patients experienced enhanced recovery of swallowing function.

Conclusions:

rTMS represents a promising neurorehabilitation strategy for dysphagia in stroke patients.
Further randomized controlled trials are needed to confirm these findings for clinical integration.
This approach may accelerate the recovery of dysphagic stroke patients.
