Perianal Fistulizing Crohn's Disease: Utilizing the TOpClass Classification in Clinical Practice to Provide Targeted...

Area of Science:

• Gastroenterology
• Inflammatory Bowel Disease
• Surgical Management

Background:

• Perianal fistulizing Crohn's disease (PFCD) presents complex challenges impacting patient quality of life.
• Traditional anatomical classifications lack specificity for diverse clinical presentations.
• The TOpClass system offers a refined approach to PFCD classification.

Purpose of the Study:

• To discuss the clinical applicability of the TOpClass classification system for PFCD.
• To provide practical guidance for integrating the TOpClass model into clinical practice.
• To align fistula management with individual patient characteristics and goals.

Main Methods:

• An international expert consensus involving gastroenterologists, IBD surgeons, and radiologists.
• Informed by multidisciplinary team management from eight high-volume fistula centers globally.
• Development of position statements to guide PFCD management based on the TOpClass system.

Main Results:

• Position statements were created to accompany the TOpClass classification system.
• Management strategies address the spectrum of PFCD, from quiescent disease to severe cases requiring proctectomy.
• Optimization of medical therapies and surgical interventions for fistula closure and symptom management is detailed across classification groups.

Conclusions:

• The article outlines the practical application of the TOpClass system in clinical settings.
• Aims to promote a pragmatic, patient-centered approach to PFCD management.
• Facilitates informed decision-making for medical and surgical treatment options in individual PFCD patients.
