Middle Rectal Valve Prolapse

Anatomy? of the Middle Rectal Valve

The middle rectal valve, also called Houston’s Valve, is one of three transverse folds within the rectum:

• Structure: These valves are made of rectal mucosa and submucosa and help control stool movement within the rectum.
• Blood Supply: The rectum receives its blood supply from three primary arteries?: the superior rectal artery?, middle rectal artery, and inferior rectal artery.
• Nerve Supply: The rectum’s nerve supply involves the pelvic splanchnic nerves, which are crucial for rectal sensation and function.

Types of Middle Rectal Valve Prolapse

1. Internal Prolapse: The valve remains inside but collapses inward, causing obstruction.
2. External Prolapse: The prolapse extends outside the anal opening, visible externally.
