Crystallized phenol treatment is a simple and inexpensive method that can be readily applied on an outpatient basis, decreasing both the recurrence rate and lost work time. We suggest that this method be considered the first-line treatment of any type of pilonidal sinus.
Although rare, PCI should be considered in the differential diagnosis of acute abdomen. Diagnostic laparoscopy and preoperative radiological tests, including computed tomography, play an important role in confirming the diagnosis.
In our study, LF and MLF procedures were associated with a lower recurrence and complication rate compared to KF. However, more randomized studies comparing different reconstruction methods after PSD excision are needed.
Crystallized phenol application is a simple, inexpensive nonoperative procedure that can be performed in an outpatient setting and is suitable for the treatment of previously operated recurrent pilonidal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
