Towards a classification for sacrococcygeal pilonidal disease – Berlin 2017
pilonidal disease classification
Introduction: Sacrococcygeal Pilonidal Disease (SPD) presents in a variety of patterns. Multiple classifications have been proposed but none are in everyday use. In order to compare treatment outcomes, a method of categorizing is required.
Methods: Discussion over e-mail between several surgeons was performed over a period of 10 months.
Results: Surgeons recognize that SPD presents in a variety of patterns but there is a lack of scientific evidence on which to base a categorization system or treatment.
Conclusion: A simple classification system suitable for everyday use can be defined.
