Injection of Freshly Collected Autologous Adipose Tissue Additional to Bascom's Cleft Lift Surgery

In brief, the right management of complex or recurrent pilonidal disease (PD) is still controversial. In our institution we treat these conditions with Bascom's cleft lift surgery. Though this approach for most parts is beneficial, a large proportion of patients will suffer from prolonged post operative healing. We have published some positive results on treating non-healing postoperative wounds after cleft lift surgery with autologous fatty cell transplantation. The overall aim of the project is to investigate whether the addition of autologous fat cell transplantation in the surgical treatment of PD reduces the incidence of patients with prolonged postoperative healing. In a double-blinded randomized controlled clinical trial, we will investigate the effect of injections of freshly harvested autologous fatty cells in addition to Bascom's cleft lift operation versus Bascom's cleft lift operation alone.
