Fistula in Ano Clinical Trial
Official title:
The Impact of 3D Anal Fistula Models on Patient Understanding and Decision Making
An anal fistula is an abnormal communication between the luminal surface of the anorectal canal and the perianal skin. Fistulas can vary in their complexity and can be challenging to treat, due to the anatomical relation to the anal sphincter complex that controls continence. In addition, fistulas can display complex features such as branches, cavities and horseshoes; where the tract travels radially around the anal canal. All these features have a role in determining the most appropriate surgical treatment option, and are key to understanding the surgical decision-making process. This study will determine patient understanding of fistula anatomy, their perception of their own understanding, their rating of how good their clinician's explanation is and how this impacts the decision-making process using standard explanation with 2D images, versus a 3D printed model of a fistula.
Previous work has established a method of using traditional two-dimensional MR images to construct and print 3D models of perianal fistula, however the clinical utility of these models in the outpatient setting and their impact on patient knowledge of disease have not yet been assessed. This study is aimed at understanding how the use of 3D printed models can influence patient understanding of disease and support them in making decisions regarding treatment. Participants attending routine outpatient appointments will have their fistula explained to them using either a standard explanation, or a 3D printed model of a fistula. They will complete a short series of questionnaires and their answers will be analysed to determine if there is any benefit of using 3D models in a clinical consultation. ;
