Pit excision with phenolisation of the sinus tract versus radical excision in sacrococcygeal pilonidal sinus disease: study protocol for a single centre randomized controlled trial

摘要

BackgroundExcision of the pit of the sinus with phenolisation of the sinus tract and surgical excision are two treatment modalities for patients with sacrococcygeal pilonidal sinus disease. Phenolisation seems to have advantages over local sinus excision as it is performed under local anaesthesia with a relatively small surgical procedure, less postoperative pain, minor risk of surgical site infection (8.7%), and only a few days being unable to perform normal activity (mean of 2.3 days). The disadvantage may be the higher risk of recurrence (13%) and the necessity to perform a second phenolisation in a subgroup of patients. Wide surgical excision of sacrococcygeal pilonidal sinus disease has a recurrence rate of 4 to 11%. The disadvantages, however, are postoperative pain, high risk of surgical site infection, and a longer period being unable to perform normal activity (mean of 10 days). The objective of this study is to show that excision of the pit of the sinus of sacrococcygeal pilonidal sinus disease with phenolisation of the sinus tract is a successful first-time treatment modality for sacrococcygeal pilonidal sinus disease accompanied by a quicker return to normal daily activity compared to local excision of the sinus.
