Understanding rectum diseases is crucial for maintaining good digestive health. This guide provides detailed descriptions and definitions related to rectum diseases, including anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention strategies, when to seek medical help, and frequently asked questions (FAQs).
Anatomy of the Rectum
Structure
The rectum is the final section of the large intestine, approximately 12 centimeters long, located between the sigmoid colon and the anal canal. It serves as a temporary storage site for feces before elimination through the anus.
Blood Supply
The rectum receives blood primarily from the superior rectal artery (a branch of the inferior mesenteric artery), the middle rectal artery (from the internal iliac artery), and the inferior rectal artery (from the internal pudendal artery). These arteries ensure adequate blood flow for its functions.
Nerve Supply
The rectum’s nerve supply comes from the autonomic nervous system, including the inferior hypogastric plexus. This network controls bowel movements and sensitivity in the rectal area.
Types of Rectum Diseases
Rectum diseases encompass a variety of conditions affecting the rectal area. Common types include:
- Hemorrhoids: Swollen blood vessels in the rectum or anus.
- Anal Fissures: Small tears in the lining of the anus.
- Rectal Prolapse: The rectum protrudes through the anus.
- Rectal Cancer: Malignant growth in the rectum.
- Inflammatory Bowel Disease (IBD): Includes Crohn’s disease and ulcerative colitis affecting the rectum.
- Diverticulitis: Inflammation of diverticula in the rectum.
- Infections: Such as sexually transmitted infections affecting the rectal area.
