Pectinate Line Fistula

A pectinate line fistula is a type of anal fistula that forms near the pectinate line, an important anatomical landmark in the anal canal. Understanding this condition involves exploring its anatomy, causes, symptoms, diagnostic methods, treatments, and prevention strategies. This guide provides clear and straightforward information to help you grasp what a pectinate line fistula is, how it affects health, and what options are available for management and treatment.

A fistula is an abnormal connection between two organs or tissues. In the case of a pectinate line fistula, this connection forms near the pectinate line in the anal canal. The pectinate line divides the anal canal into two parts and is crucial for understanding various anorectal conditions. A fistula in this area can cause discomfort, pain, and other symptoms, impacting daily life.

Anatomy of the Pectinate Line

Structure

The pectinate line is an anatomical ridge in the anal canal, marking the boundary between the upper two-thirds and the lower third. Above the pectinate line, the anal canal is lined with columnar epithelium, while below it, the lining changes to stratified squamous epithelium. This line also separates different types of blood vessels, nerves, and lymphatic drainage.

Blood Supply

• Above the Pectinate Line: Receives blood from the superior rectal artery.
• Below the Pectinate Line: Supplied by the inferior rectal artery.

This division is important for understanding the spread of infections and the development of fistulas.

Nerve Supply

• Above the Pectinate Line: Sensory innervation is visceral and less sensitive to pain.
• Below the Pectinate Line: Somatic innervation makes this area more sensitive to pain and temperature.

This difference affects how symptoms are experienced and reported by patients.

Types of Pectinate Line Fistulas

Pectinate line fistulas can be classified based on their location and the structures they involve. Here are some common types:

1. Intersphincteric Fistula: Between the internal and external sphincter muscles.
2. Transsphincteric Fistula: Passes through both sphincter muscles.
3. Supersphincteric Fistula: Extends above the sphincter muscles.
4. Extrasphincteric Fistula: Extends from the rectum or sigmoid colon to the skin.

Understanding the type helps in planning effective treatment.
