Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.

- Endosonography (endoscopic ultrasound (EUS); ultrasound examination performed from the inside, i.e., the ultrasound probe is brought into direct contact with the internal surface (for example, the mucosa of the stomach/intestine) by means of an endoscope (optical instrument)).
- Magnetic resonance imaging (MRI), biopsy (tissue sampling), etc. – for differential diagnosis of cryptogenic perianal abscesses (purulent inflammation in the tissues around the anus) and fistulas
