How is Fistula Detected?
Introduction
An anal fistula is an uncommon passage that develops between the inner lining of the anus and the outer skin, typically occurring in the upper part of the anus where the anal glands are situated. When an infection extends to these glands, it can result in the formation of a fistula, often referred to as a perianal abscess. Alternatively, it may be termed a perianal fistula due to its location around the anus.
Approximately half of individuals with infected anal glands will eventually develop a fistula, with abscess formation being a common precursor, responsible for around 75% of anal fistulas. Dealing with such medical conditions can exert financial strain on both the individual and their family. Consequently, obtaining health insurance is strongly recommended to alleviate the burden during medical crises.
In this blog, we will discuss the ways to get a fistula diagnosis.
Diagnosis of Fistula
- Anal fistula diagnosis requires your doctor to examine the area and inside of the anus carefully.
- The doctor can use several screening techniques to identify the fistula tunnel
- MRI – It can help locate the tunnel that extends to the fistula and provide clear and detailed images of the sphincter muscle and other parts of the pelvic floor.
- Endoscopic Ultrasound – The high-frequency sound waves can help identify the fistula and the sphincter muscles, including the nearby surrounding tissues.
- Fistulography – In this procedure, a medical professional conducts an x-ray to locate the anal fistula tunnel.
- Fistula Probe – it is an instrument that is designed especially to be inserted into the fistula to locate the fistula tunnel.
- Anoscope – It is a small size endoscope used to view the anal canal.
- Injected dye solution – It is used to identify and locate the fistula opening.
- Flexible sigmoidoscopy or colonoscopy – Sigmoidoscopy or colonoscopy are the two techniques used to diagnose the large intestine with the help of an endoscope attached to it. Sigmoidoscopy examines the lower section (sigmoid colon), while colonoscopy assesses the entire colon. It is essential when there is a need to detect disorders caused by ulcerative colitis or Crohn’s disease.
- Examination under the influence of anaesthesia – The colon and rectal surgeon may recommend anaesthesia during the examination of the fistula as it may help investigate the fistula tunnel and can help in identifying the possible complications.
Conclusion
In this blog, we’ve explored the anal fistula diagnosis, a condition that can be notably painful and predominantly affects men. Understanding the pathway to the fistula tunnel is crucial for effective treatment. To achieve this, various diagnostic techniques are utilized, including MRI, examination under anaesthesia, anoscopy and a fistula probe. Having health insurance for both oneself and one’s family is essential to alleviate financial burdens in times of medical emergencies.
