Summary
Megaesophagus, a disorder causing esophageal dilation and reduced peristalsis, has congenital and acquired forms. Diagnosing the underlying cause is crucial for effective treatment and prognosis.
Area of Science:
- Veterinary Medicine
- Gastroenterology
- Pathology
Context:
- Megaesophagus involves esophageal dilation and impaired peristalsis.
- It presents in congenital and acquired forms.
- Acquired megaesophagus links to various systemic disorders.
Purpose:
- To define megaesophagus and its classifications.
- To outline associated conditions and clinical signs.
- To emphasize diagnostic approaches and treatment variability.
Summary:
- Megaesophagus is characterized by esophageal dilation and decreased peristalsis, with congenital and acquired origins.
- Acquired forms are linked to gastrointestinal, endocrine, immune, neuromuscular, paraneoplastic, and toxic conditions.
- Clinical signs include regurgitation, weight loss, coughing, and halitosis, with diagnosis often requiring radiography and further investigation.
Impact:
- Highlights the importance of identifying underlying causes for tailored management.
- Informs veterinary professionals on diagnostic pathways for megaesophagus.
- Stresses the variable prognosis dependent on the etiology of megaesophagus.

01:27Esophageal 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)...
01:50What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
01:28Esophageal 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.

01:24Esophagus
The esophagus, a muscular conduit linking the pharynx and stomach, measures roughly 10 inches (25.4 cm) and sits behind the trachea. It remains collapsed when not swallowing. The esophagus follows a predominantly straight path through the thoracic mediastinum and enters the abdominal cavity through a diaphragmatic opening known as the esophageal hiatus.
