Understanding Upper Rectum Diseases is crucial for maintaining digestive health. This guide provides detailed descriptions, definitions, and essential information about the upper rectum, its anatomy, various diseases, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention methods, and when to seek medical help. Additionally, we address frequently asked questions to enhance your knowledge.
Anatomy of the Upper Rectum
Structure
The rectum is the final section of the large intestine, connecting the colon to the anus. It measures about 12 centimeters (4.7 inches) in length and is divided into three parts:
- Upper Rectum (Superior Rectum): This is the first third of the rectum, closest to the sigmoid colon. It acts as a temporary storage site for feces before they are expelled.
- Middle Rectum: The central part of the rectum.
- Lower Rectum (Inferior Rectum): The final third, leading directly to the anus.
Blood Supply
The upper rectum receives blood primarily from the superior rectal artery, a branch of the inferior mesenteric artery. Adequate blood flow is essential for the health and function of the rectal tissues.
Nerve Supply
The upper rectum is innervated by the superior rectal nerves, which are part of the autonomic nervous system. These nerves control bowel movements and the sensation within the rectum.
Types of Upper Rectum Diseases
Upper rectum diseases encompass a range of conditions affecting the upper third of the rectum. Common types include:
- Hemorrhoids: Swollen veins in the rectum or anus.
- Rectal Prolapse: When the rectum protrudes through the anus.
- Rectal Cancer: Malignant growths in the rectum.
- Inflammatory Bowel Disease (IBD): Including Crohn’s disease and ulcerative colitis.
- Rectal Polyps: Benign growths that can become cancerous.
- Diverticulitis: Inflammation of diverticula in the rectum.
- Rectal Infections: Bacterial, viral, or parasitic infections.
- Fissures: Small tears in the rectal lining.
- Abscesses: Pus-filled cavities resulting from infections.
- Rectal Varices: Enlarged veins in the rectum, often related to liver disease.
