Demographic and clinical characteristics, symptom duration, pit count, number of phenol sessions (2 vs. 3), inter\u2010session intervals, and total treatment duration were recorded. All patients completed scheduled clinical reassessment at 5\u2009weeks and 3 months. Treatment\u2010related abscess and recurrence during follow\u2010up were documented. Continuous variables are presented as mean \u00b1 standard deviation and median (minimum\u2013maximum). Comparisons between the two\u2010session and three\u2010session groups were performed with the Mann\u2013Whitney\n                    <jats:italic>U<\/jats:italic>\n                    test for continuous variables and Fisher's exact test for categorical variables.\n                    <jats:italic>Results<\/jats:italic>\n                    : The cohort was predominantly male (75%), with a mean age of 29.23\u2009\u00b1\u20099.85\u2009years and a mean body mass index of 25.81\u2009\u00b1\u20093.85 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    ; 62.5% were smokers. Symptom duration was 6.80\u2009\u00b1\u20097.20 months, and mean pit count was 1.90\u2009\u00b1\u20090.93. Two sessions were sufficient in 42.5% (17\/40), whereas 57.5% (23\/40) required three sessions. The interval between the first and second sessions was 11.32\u2009\u00b1\u20093.30\u2009days, and the interval between the second and third sessions was 11.96 \u00b1\u20093.23\u2009days in patients who underwent three sessions; overall treatment duration was 18.2\u2009\u00b1\u20097.58\u2009days. No patient was lost to follow\u2010up. Pit burden was the strongest determinant of requiring a third session: pit count was significantly higher in the three\u2010session group than in the two\u2010session group (2.39\u2009\u00b1\u20090.89 vs. 1.24\u2009\u00b1\u20090.44,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;\u20090.001), and all patients with \u2265\u20093 pits required three sessions. Smoking status (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20091.000) and body mass index (BMI) (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.208) were not associated with session requirement. Treatment\u2010related abscess developed in 12.5% (5\/40), and recurrence during the 3\u2010month follow\u2010up was observed in 12.5% (5\/40); notably, all such events occurred in the three\u2010session group (0\/17 vs. 5\/23,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.061 for both comparisons).\n                    <jats:italic>Conclusion<\/jats:italic>\n                    : In this single\u2010centre series, crystallised phenol provided acceptable short\u2010term outcomes and a relatively short treatment course in presacral pilonidal sinus disease. Pit count emerged as the main determinant of requiring a third session, whereas smoking status and BMI were not associated with session requirement. Larger studies with longer follow\u2010up are needed to clarify predictors of recurrence and to determine whether higher session requirements simply reflect disease complexity or also influence outcome.\n
