Use of three-dimensional virtual images for planning surgery of complex anal fistulas: a new technology available via smartphone
Treatment of complex anal fistulas is considered a challenge for most surgeons. Although many surgical techniques are available, it is very important to identify fistula tracts before and during the surgical procedure . Therefore, technologies should be developed to improve preoperative planning. As a result, the best surgical approach will be chosen, and proper healing of the perianal region will be optimized.
In the past few years, several specialties have benefitted from three-dimensional (3D) patient-specific anatomical models to diagnose diseases and plan complex operations. However, there are only few reports describing the use of new technologies for planning rectal and anal surgery [2, 3, 4, 5]. The aim of this study was to describe the process of creating a 3D image from patient anatomy. It also addresses preoperative surgical planning for the correction of complex anal fistulas using magnetic resonance imaging (MRI) through access by smartphone or tablet.
