Effects of methylene-blue staining on the extent of pilonidal sinus excision

Abstract

These data suggest that excised specimens with MBS had significantly larger volumes of the excised specimen compared with specimens that were not stained with MB. MBS of a fistula system could enable such a system to be marked sufficiently, thereby facilitating complete resection of a PS.

Methylene Blue Provides an Efficient Resection for the Treatment of Pilonidal Sinus Disease

“…In our study, we determined that the volume of excised specimen was lesser in SPSD treated with MBS compared with those without MBS. The effect of MBS on the volume of excised SPSD specimens has been only once described previously (14). With contrast to previous study, it was demonstrated that the volume of excised specimens was decreased remarkably with MB usage in this study.…”

“…This is probably the reason why some specimens presented as multiple parts. Thus, they also assumed that not only the antimicrobial effect but also the more radical excision extent may have contributed to the recurrence reduction (14) as also reported before (12). In our study, we determined that the volume of excised specimen was lesser in SPSD treated with MBS compared with those without MBS.…”

“…With 14.9 years control follow ups, it has observed that recurrence reduced from 30% to 16% (12). A clinical practice noticed in some cases that the change of the excision extent was seen when the MB was used (14). This is probably the reason why some specimens presented as multiple parts.…”

“…In both groups Karydakis flap, the sinus tract was removed down to the sacrococcygeal fascia by an asymmetric semilateral elliptic incision as described in the Karydakis technique (14). The cranial and caudal tips of the incision were placed at opposite sides of the perianal opening.…”

“…It also has been shown that methylene-blue staining (MBS) was applied significantly less often in emergency cases (13). There are only few publications on the use of MB in SPSD (14).…”
