Esophageal Strictures-II: Clinical Features and Management01:26

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: Introduction01:30

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...
Esophageal Achalasia01:27

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)...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

Summary
This summary is machine-generated.

A custom dynamic stent (DS) offers an effective alternative to repeated dilations for severe esophageal strictures. This innovative stent improves motility and allows passage of food and secretions, with an 80.7% success rate in a pediatric study.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Biomedical Engineering

Background:

  • Recurrent esophageal strictures, often post-surgical, necessitate repeated dilations.
  • Existing esophageal stents can impede motility and passage of food and secretions.

Purpose of the Study:

  • To evaluate the efficacy and safety of a custom dynamic stent (DS) for treating severe, recurrent post-surgical esophageal strictures in children.
  • To compare the DS approach to traditional serial dilation methods.

Main Methods:

  • A custom-designed dynamic stent (DS) was fashioned from silicon drains and inserted coaxially on a nasogastric tube.
  • Stent placement was performed after dilation (Savary-Gilliard) under fluoroscopic guidance in 26 pediatric patients.
  • Patients received dexamethasone and proton pump inhibitors post-procedure.

Main Results:

  • The custom DS was effective in 21 out of 26 patients (80.7%) with recurrent strictures.
  • The stent remained in place for at least 40 days.
  • Two major complications (subclavian-esophageal fistula) occurred, resulting in a 6.7% complication rate.

Conclusions:

  • The custom dynamic stent (DS) is an effective and safe treatment option for severe and recurrent post-surgical esophageal strictures in pediatric patients.
  • The DS improves esophageal motility and facilitates passage of food and secretions.
  • Surgical intervention remains a rescue strategy for refractory cases.
