The primary outcome, disease recurrence, was assessed using Kaplan\u2013Meier analysis; secondary outcomes included healing rates, healing time, and complications. Univariable risk factor analysis was performed. Follow\u2010up through telephone interviews and review of medical records achieved a 90.3% completion rate at a median of 4.0\u00a0years (IQR: 3.6\u20135.0\u00a0years).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Recurrence rates were significantly higher in recurrent versus primary disease (RR 1.76, 95%CI: 1.30\u20132.40,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.001), with 12\u2010month rates of 34.8% versus 16.8% respectively. At the final follow\u2010up, the recurrence rate was 34.6% for primary disease and 60.8% for recurrent disease. The time to recurrence was accelerated in recurrent cases (median, 11.4 vs. 14.0\u00a0months,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05). Despite comparable initial healing rates (75.4% primary, 68.0% recurrent), recurrent disease required 10 additional days for complete healing (56 vs. 46\u00a0days,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001). Sequential SiLaC procedures, when necessary, achieved final healing rates exceeding 90% in both groups with minimal complications (5.8%). Three factors predicted recurrence: recurrent disease status in all patients; within recurrent cases, symptom duration greater than 38\u00a0weeks (RR 2.14) and four or more medial openings (RR 2.07); all\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>SiLaC demonstrated acceptable recurrence rates for primary SPSD comparable to other minimally invasive techniques at long\u2010term follow\u2010up, but significantly poorer outcomes in recurrent disease.
