Higher surgical caseloads lower recurrence rates in pilonidal sinus disease

Analysis of 1,074 studies involving 130,599 patients revealed that higher annual surgical volumes significantly decrease recurrence rates for pilonidal sinus disease. Specifically, patients treated in centers performing 30 or more surgeries annually showed improved outcomes, with 5-year recurrence rates dropping to 12.5%. However, midline closure surgeries did not benefit from increased caseloads, maintaining high recurrence rates across all volume categories. These findings suggest the importance of surgical experience in achieving better patient outcomes.
