Perianal Space Prolapse

Perianal space prolapse occurs when tissues around the anus (the opening at the end of the digestive tract) protrude or bulge out due to weakening or damage. This can lead to discomfort and various complications.

Anatomy

Structure

• Anus: The opening at the end of the digestive tract.
• Perianal Area: The skin and tissues surrounding the anus.
• Rectum: The part of the intestine just above the anus.

Blood Supply

• Arteries: The inferior mesenteric artery and internal pudendal artery supply blood to the perianal region.
• Veins: Venous drainage occurs through the inferior rectal vein, which drains into the internal pudendal vein.

Nerve Supply

• Sensory Nerves: The inferior rectal nerve (a branch of the pudendal nerve) provides sensation to the perianal area.
• Motor Nerves: The pudendal nerve controls the muscles around the anus.

Types of Perianal Space Prolapse

1. Complete Prolapse: All layers of the rectal wall protrude.
2. Partial Prolapse: Only some layers protrude.
3. Internal Prolapse: The rectum falls but remains inside the anal canal.
4. External Prolapse: The rectum protrudes outside the body.
