Dr. Mohammed Hatem AlsubaihPus, mucus or stool leakage?
Discharge from a skin opening differs from mucus passed with stool or fecal staining. Colour alone cannot identify the cause. Record where it comes from, its consistency and whether swelling improves after drainage.
What does examination look for?
The clinician checks for a fistula opening, skin irritation and problems inside the anal canal. Repeated drainage from the same site after an abscess suggests a fistula may need investigation. Rectal discharge may instead require assessment for inflammation or infection.
Will MRI help?
MRI can address a suspected deep, recurrent or branching fistula. It does not explain every case of mucus or leakage and cannot replace examination. Bring previous drainage or operation reports.
What can I do meanwhile?
Clean gently, pat dry and avoid fragranced products or probing the opening. Increasing pain, swelling or fever needs urgent assessment, even if discharge suddenly decreases.
