Summary
Diaphragmatic hernias in horses have a poor prognosis, but operable lesions offer a fair chance for long-term survival. Factors like lesion size, location, and patient age significantly influence outcomes for horses with diaphragmatic hernia.
Area of Science:
- Veterinary Surgery
- Equine Medicine
- Surgical Pathology
Background:
- Diaphragmatic hernia is a serious condition in horses.
- Accurate diagnosis and prognostic indicators are crucial for effective treatment.
Purpose of the Study:
- To analyze factors influencing short- and long-term survival in horses with diaphragmatic hernia.
- To evaluate the prognostic significance of clinical, laboratory, and surgical findings.
Main Methods:
- Retrospective case series of 44 horses diagnosed with diaphragmatic hernia.
- Data collected included history, physical examination, laboratory results, and surgical/necropsy findings.
- Statistical analysis (logistic regression, Fisher exact test) identified factors associated with survival.
Main Results:
- Survival to discharge was achieved in 7 of 26 surgically treated horses.
- Long-term survival (≥1 year) was observed in 5 horses.
- Significant prognostic factors included younger age (≤2 years), normal peritoneal fluid, minimal compromised viscera (<50% small intestine), and smaller (<10 cm) ventral diaphragmatic tears.
Conclusions:
- Diaphragmatic hernia in horses carries a guarded prognosis.
- Lesion size and location are critical prognostic indicators.
- Horses with operable diaphragmatic hernias have a fair prognosis for long-term survival.

01:25Hiatal Hernia
60
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or...

01:07Intestinal Obstruction II: Pathophysiology
37
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

01:22Esophageal Perforation-I: Introduction
839
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....

01:28Esophageal Perforation-II: Clinical Manifestations and Management
1.0K
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.

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...
