Anal longitudinal folds are natural structures found in the anus. The anus is the last part of the digestive system and the opening through which stool exits the body. Inside the anal canal, there are folds or ridges that run vertically along the length of the canal. These are called longitudinal folds or columns of Morgagni.
These folds help with the passage of stool and are part of the normal anatomy of the anal canal. However, certain conditions, including cancer, can affect these folds, leading to symptoms and health issues.
Anatomy of Anal Longitudinal Folds
Structure
- Location: Found in the anal canal, which is the final section of the large intestine.
- Appearance: Vertical ridges or folds that run along the inside of the anal canal.
- Function: They help in the passage of stool and maintaining the seal of the anus to prevent leakage.
Blood Supply
- The anal canal, including its longitudinal folds, receives blood from the inferior rectal arteries, which are branches of the internal pudendal artery. This ensures proper blood flow to the area.
Nerve Supply
- Nerve supply to the anal area comes from both the autonomic nervous system (which controls involuntary actions like internal sphincter relaxation) and the somatic nervous system (which controls voluntary movements like the external sphincter).
Types of Conditions Related to Anal Longitudinal Folds and Cancer
- Benign (Non-Cancerous) Conditions:
- Hemorrhoids: Swollen blood vessels in the anal area, sometimes associated with longitudinal folds.
- Anal Fissures: Small tears in the lining of the anus that can affect the folds.
- Rectal Prolapse: When part of the rectum slips out of place and may involve the folds.
- Malignant (Cancerous) Conditions:
- Anal Cancer: A type of cancer that can develop in the anal canal, sometimes impacting the longitudinal folds.
- Colorectal Cancer: Cancer of the colon or rectum, which can spread to the anal area and affect the folds.
Possible Causes of Cancer in the Anal Longitudinal Folds
- Human Papillomavirus (HPV) infection
- Smoking
- Chronic inflammation
