简要总结
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.
详细描述
The overall aim of the project is to investigate whether the addition of autologous fatty cell transplantation in the surgical treatment of pilonidal disease (PD) reduces the incidence of patients with prolonged postoperative healing. In a double-blinded randomized controlled clinical trial, the investigators 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.
The investigators hypothesize that addition of autologous fatty cell injection to Bascom's cleft lift operation for pilonidal disease will reduce the proportion of patients with poor postoperative healing compared to patients in the control group who are treated with Bascom's cleft lift operation alone.
The primary endpoint of this study is healing of the pilonidal lesion (max 1 defect ≤5mm, no undermining) after 4 weeks and 12 weeks.
Further, symptom development, postoperative pain, complication rate, time to healing and recurrence rates are also explored.

盲法说明
Patients will all receive BCL surgery and all have two small incisions in in the lumbar region with local anesthetic injection and compression bandages. Only the intervention group with have fatty cells harvested and injected in the surgical wound. The out comes assessor is blinded to which treatment has been given.
