Canine Rectal Prolapse Study Guide

Overview and Clinical Importance

Rectal prolapse is a condition in which one or more layers of the rectum protrude through the anus due to persistent tenesmus or weakness of supporting structures. This condition is commonly encountered in young dogs, particularly puppies with severe parasitic infections or diarrhea. Understanding the pathophysiology, diagnostic approach, and treatment options is essential for the NAVLE, as rectal prolapse represents a common gastrointestinal emergency requiring prompt intervention.

The clinical significance of rectal prolapse extends beyond the visible tissue protrusion. Without timely treatment, the prolapsed tissue can become edematous, ischemic, necrotic, and ultimately lead to life-threatening complications including sepsis. The key to successful management lies in identifying and treating the underlying cause while addressing the prolapse itself.

Anatomy Review

Rectal and Anal Anatomy

The rectum is the terminal portion of the large intestine, beginning at the pelvic inlet and ending ventral to the second or third caudal vertebrae at the anal canal. It is approximately 5-7 cm long in medium-sized dogs and serves as a storage reservoir for feces before defecation.
