Insights

Endoscopic local infiltration of mitomycin C (MMC) effectively treats refractory postcorrosive esophageal strictures in children. This safe treatment significantly reduces dysphagia and improves dilation outcomes.

Area of Science:

  • Pediatric Gastroenterology
  • Endoscopic Therapeutics
  • Otolaryngology

Background:

  • Refractory postcorrosive esophageal strictures (OS) pose a significant challenge in pediatric care.
  • Conventional treatments like dilation often require multiple sessions and may have limited long-term success.

Purpose of the Study:

  • To evaluate the efficacy and safety of endoscopic local infiltration of mitomycin C (MMC) in children with refractory OS.
  • To assess the impact of MMC on dysphagia score (DS) and periodic dilation index (PDI).

Main Methods:

  • A prospective study included 17 children with refractory postcorrosive OS.
  • Mitomycin C (MMC) was endoscopically infiltrated at the stricture site post-dilation.
  • Dysphagia score (DS) and periodic dilation index (PDI) were the primary outcome measures.

Main Results:

  • Median DS improved from 3 to 0 (P < 0.001), with 94% of patients becoming dysphagia-free at 6 months.
  • Median PDI decreased from 1 to 0.75 (P = 0.052).
  • Minor postdilation bleeding occurred in 7 patients, resolving spontaneously without transfusion; no infiltration-related complications were noted.

Conclusions:

  • Endoscopic MMC infiltration is a safe and effective adjunct to esophageal dilation for pediatric refractory OS.
  • This technique significantly improves swallowing function and reduces the need for repeated dilations.

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...

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

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...

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Biological Effects of Radiation02:59

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
