Insights

VACTERL associations are common in children with esophageal atresia/tracheoesophageal fistula (EA/TEF) and anorectal malformation (ARM). Cardiac issues are more frequent with EA/TEF, while spinal and renal anomalies are more common with ARM.

Area of Science:

  • Pediatric Surgery
  • Medical Genetics
  • Developmental Biology

Background:

  • VACTERL (Vertebral, Anal, Cardiac, Tracheo-Esophageal, Renal, Limb) anomalies represent a complex spectrum of congenital malformations.
  • Understanding the co-occurrence patterns of these anomalies is crucial for comprehensive patient management and genetic counseling.

Purpose of the Study:

  • To compare the incidence and types of VACTERL associations in pediatric patients undergoing surgery for esophageal atresia/tracheoesophageal fistula (EA/TEF) versus anorectal malformation (ARM).

Main Methods:

  • Utilized the Pediatric Health Information System (PHIS) database from 2004-2012, encompassing data from 43 children's hospitals.
  • Identified and cross-referenced surgical records for EA/TEF and/or ARM with diagnoses of vertebral, cardiac, renal, and limb anomalies.
  • Analyzed records for children meeting criteria for VACTERL diagnosis (3 or more associated anomalies).

Main Results:

  • In 2689 EA/TEF repairs, VACTERL associations included: 25.5% vertebral, 11.6% ARM, 59.1% cardiac, 21.8% renal, and 7.1% limb defects. 33.4% met VACTERL criteria.
  • In 4962 ARM repairs, VACTERL associations included: 31.5% vertebral, 40.4% cardiac, 7.0% EA/TEF, 34.7% renal, and 7.2% limb defects. 36.2% met VACTERL criteria.
  • Significant differences in anomaly clusters were observed between the two groups.

Conclusions:

  • VACTERL associations are prevalent in both EA/TEF and ARM patient cohorts.
  • Congenital heart disease is a more frequent co-occurrence in EA/TEF, whereas vertebral and renal/urinary anomalies are more common in ARM.
  • These findings highlight distinct patterns of VACTERL component associations based on the primary congenital anomaly.

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 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 Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

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....
