To drain or not to drain following a Sistrunk procedure: A dual institutional experience.

Introduction: A Sistrunk procedure is the standard operative management of patients with thyroglossal duct cysts. Drain placement is commonly employed with the goal of reducing postoperative complications. This study investigates the association between drain use and relevant postoperative complications following pediatric Sistrunk procedures.

Methods: Retrospective cohort study evaluating 295 pediatric patients treated between 2007 and 2016 at two tertiary care children's hospitals.

Results: The mean age of the study population was 5.6 years (SD 4.0). A drain was utilized in 234 cases (79.3%). The mean procedural duration was 108 min (SD 48), and significantly longer in patients receiving a drain. Early postoperative complications included seroma (5.8%), secondary infection (3.4%), wound breakdown (2.0%) and hematoma (0.3%). The risk of such complications did not significantly differ between patients without drain placement (9.8%) versus those who underwent surgical drain placement (12.0%) after accounting for age and history of preoperative infection (adjusted RR = 0.86; 95% CI: 0.37, 1.98; p = 0.72). In the subgroup analysis, findings were consistent across institutions, age category, history of infection, and primary versus secondary procedure.

Conclusion: This dual institutional study found drain placement during a Sistrunk procedure may not reduce rates of common postoperative complications, even in longer duration cases in which a drain is more frequently placed. This data suggests a Sistrunk procedure may be safely performed without drain placement in select cases.
