A 16-year experience in treating XXXX with a "conservative" Sistrunk approach.

@entity1 @entity281 @entity11677
UNASSIGNED: Although Sistrunk operation is the standard method to treat @entity11677 , the reported recurrence rates after a "classic" or "modified" Sistrunk procedure still varied from 0 to 15.8  %, indicating the existence of some technical uncertainties. While simple cystectomy has been recognized as the most important prognostic factor predicting @entity11677 recurrence, whether other clinico-pathological parameters also affect disease recurrence has not been well studied. We retrospectively reviewed the medical records of all @entity1 who underwent @entity11677 surgery between June 1998 and June 2014 at our institution. Among the 180 primary @entity1 , 160 @entity1 received a "conservative" Sistrunk operation, while the remaining 20 @entity1 received simple cystectomy only. Five @entity1 (2.8  %, 5/180) had recurrence. Four of them received simple cystectomy while 1 had "conservative" Sistrunk operation. In univariable analysis, age (p  =  0.02), history of previous @entity281 (p  =  0.004) and the type of resection (p  =  0.001) were significantly correlated with disease recurrence. In multivariable analysis, the type of resection turned out to be the most important factor (p  =  0.03) related to recurrence. In the most parsimonious model selected by backward elimination, both history of @entity281 (p  =  0.048) and the type of resection (p  =  0.02) were important predictors of postoperative recurrence. Our results demonstrated that a "conservative" Sistrunk approach could provide a comparably low recurrence rate (0.6  %, 1/160) in dealing with primary thyroglossal dust cysts. Routine dissection of suprahyoid tissue may not be imperative. Overall, the type of resection and history of @entity281 are the most important predictors of recurrence for @entity11677 .
