Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

1.1K
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 Perforation-I: Introduction

697
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....

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.4K
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

89.3K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Neurulation01:30

Neurulation

46.9K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Esophageal Strictures-II: Clinical Features and Management

841
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...

Summary

Neonatal intussusception is rare and presents differently based on gestational age. This review identifies three distinct forms: prenatal, preterm postnatal, and term postnatal intussusception.

Area of Science:

  • Pediatric Surgery
  • Neonatal Medicine
  • Gastrointestinal Diseases

Background:

  • Intussusception is common in infants, typically with clear symptoms and good outcomes.
  • Neonatal intussusception is exceptionally rare and lacks a defined clinical presentation.
  • Clinical signs vary with gestational age, intestinal response, and infant's gestational age.

Observation:

  • Presents two new cases of neonatal intussusception.
  • Reviews global literature on neonatal intussusception.
  • Categorizes neonatal intussusception into three distinct entities based on timing and infant maturity.

Findings:

  • Prenatal (intrauterine) intussusception presents unique characteristics.
  • Postnatal intussusception in preterm infants differs clinically.
Keywords:

  • Postnatal intussusception in term infants has distinct features.

    • Implications:

    • Highlights the need for tailored diagnostic and management approaches for each type.
    • Emphasizes the importance of considering gestational age in neonatal intussusception diagnosis.
    • Contributes to a better understanding of this rare neonatal surgical emergency.
