Chronic Pain
The clinical research activity of Groupe Hospitalier Diaconesses Croix Saint Simon is centered on chronic idiopathic ano-perineal pain, with interest in persistent pain syndromes affecting the anal and perineal regions.
- Chronic idiopathic ano-perineal pain
- Persistent pelvic and perineal pain
- Anal pain management
The sponsor’s research focus reflects a clinical interest in pain conditions where the underlying cause is not clearly identified and symptom control remains a key therapeutic concern.
Perineal and Pelvic Analgesia
Its trial activity includes the assessment of perineal block techniques and local anesthetic infiltration for relief of pain in the ano-perineal area.
- Posterior perineal block
- Neurostimulation-guided analgesia
- Local anesthetic infiltration
This area of interest is aligned with procedural pain control in anorectal and perineal disorders.
Anorectal Pain Disorders
The sponsor is involved in research on anorectal pain presentations that require targeted clinical evaluation and symptom-focused intervention.
- Idiopathic anorectal pain
- Perineal pain syndromes
- Functional pain conditions
These studies are relevant to clinical care pathways for patients with localized pain in the lower pelvic and anorectal region.
