Clinical Causes: Inflammatory bowel diseases, such as Crohn's disease or ulcerative colitis Infections that involve the rectal area, including abscesses Trauma or injury to the rectal area, possibly from surgery or injury Previous radiation therapy to the pelvic region Chronic constipation or other conditions that cause repeated straining Malignancies or tumors affecting the rectal region

Key Symptoms: Persistent pain or discomfort around the anus or rectum Recurrent or ongoing drainage of pus or stool from an opening near the anus Swelling or redness around the affected area Fever or general feelings of being unwell, in some cases Presence of an abnormal tunnel or opening that may be noticed under the skin Difficulty with bowel movements or feelings of incomplete evacuation

Diagnosis Path: Digital rectal examination to palpate abnormalities Imaging studies such as MRI (Magnetic Resonance Imaging) or endoanal ultrasound to map the fistula's course Fistulograms, which involve injecting contrast dye into the fistula to visualize its path Examination under anesthesia (EUA) for a thorough assessment, especially if surgery is planned Laboratory tests, if infection or other complications are suspected

Treatment Protocols: Surgical procedures to remove or close the fistula, such as fistulotomy, seton placement, or advanced techniques like flap repair or advancement procedures Use of setons, which are specially designed stitches or drains to keep the fistula open and allow for infection control and tissue healing Antibiotic therapy if infection is present Management of underlying conditions, such as controlling Crohn's disease Postoperative care including wound cleaning and lifestyle modifications to support healing In some cases, staged surgeries or specialized intervention may be necessary for complex fistulas
