The puborectalis muscle is an important part of the pelvic floor that helps maintain bowel continence and supports the lower part of your digestive tract. An infection in this muscle is rare but can be quite painful and disruptive. In this guide, we will explain what a puborectalis muscle infection is, how it develops, its causes, symptoms, ways to diagnose it, and different treatments.
A puborectalis muscle infection is an inflammation or infection affecting the puborectalis muscle—a key muscle in the pelvic floor. This infection can occur when bacteria or other germs invade the muscle tissue, causing pain, swelling, and sometimes affecting bowel control. Since the puborectalis is part of the complex network of muscles that help hold the rectum in place, an infection here may lead to symptoms that interfere with normal daily activities.
Pathophysiology:
1. Structure and Anatomy
- Location: The puborectalis muscle forms a U-shaped sling around the rectum and is part of the levator ani group of muscles in the pelvic floor.
- Anatomy: It extends from the pubic bone (in the front of the pelvis) to the back of the rectum. Its unique shape is crucial in creating the anorectal angle that helps maintain continence.
2. Blood Supply
- Primary Blood Vessels: The blood supply to the puborectalis comes mainly from branches of the internal iliac arteries. A good blood supply is necessary for delivering oxygen and nutrients to help the muscle function and heal if injured or infected.
3. Nerve Supply
- Nervous Control: The puborectalis muscle is controlled by nerves from the sacral plexus. These nerves are responsible for muscle contraction and help maintain the tone needed for continence.
- Sensory Input: Nerve endings in the muscle also relay pain signals if an infection or injury occurs.
4. Functions
- Maintaining Continence: The puborectalis muscle plays a vital role in keeping the rectum in a loop, creating an angle that prevents involuntary leakage of stool.
- Support for Pelvic Organs: It supports the pelvic organs by contributing to the overall strength and stability of the pelvic floor.
- Facilitating Defecation: During bowel movements, the relaxation of this muscle helps in the proper passage of stool.
Types of Puborectalis Muscle Infection
While infections of the puborectalis muscle are not very common, they can vary in severity and presentation. Here are the types often recognized:
- Acute Bacterial Infection: This is usually sudden and results from a bacterial invasion, causing pain and swelling.
- Chronic Infection: A long-standing infection that may not show severe symptoms initially but can lead to persistent discomfort.
- Abscess Formation: In some cases, the infection may lead to an abscess (a pocket of pus) within the muscle tissue.
- Post-Surgical Infection: Infection that occurs after a pelvic surgery, where the puborectalis muscle is either directly involved or affected by nearby infection.
