Original Article



Different surgical techniques for pilonidal disease have been described in the literature. In this study, our aim was to evaluate the influence of routine cavity drainage in the Karydakis flap technique.


As much as 50 male patients with pilonidal sinus who underwent the Karydakis flap operation were evaluated prospectively.The patients were assigned randomly into two groups (Group 1 with suction drain; Group 2 fibrin glue).


Fluid collection was encountered in 8 out of 50 patients (6.25%): 6 in Group 2 (24%) of which 4 experienced superficial, healed with simple dressing, the other 2 with substantial dehiscence healed with wound dressing; 2 in Group 1 (8%) were treated with wound punctures.There has been no recurrence in any of the patients during the follow-up period.The Karydakis flap operations can be performed with a near zero recurrence rate with the use of drains.


We recommend the use of fibrin sealant with Karydakis flap procedure, but further studies are needed to confirm this conclusion.

Suppl. Fig. 6 After deep absorbable sutures are placed 6 ml fibrin sealant (CryoSeal FS System, Thermogenesis, Rancho Cordova, USA) was sprayed on to surgical site and under the flap using a double-barrel syringe and spray tip applicator Afterward, a second layer of absorbable sutures are than placed approaching the two surfaces to close the dead space.
