Adipo-fascio-cutaneous Flaps in the Treatment of Pilonidal Sinus: Experience with 50 Cases

To retrospectively analyse the results of pilonidal sinus managed using wide excision with primary eccentric closure with various adipo-fascio-cutaneous flaps. Data from 50 consecutive patients who had elective surgery for chronic pilonidal sinus with wide excision of all the sinuses and primary eccentric closure with various adipo-fascio-cutaneous flaps (40 lateral advancements, 4 Z-plasties, four rotations, 1 rhomboid and 1 V-Y advancement) were retrospectively analysed. Special emphasis was placed on partial obliteration of the natal cleft, duration of wound healing, postoperative morbidity and hospital stay, loss of work days, cosmetic outcome and recurrence. In all patients, partial obliteration of the natal cleft was achieved by eccentric primary wound closure, with good cosmesis. Superficial necrosis of the flaps occurred in five patients (3 Z-plasties, 2 rotation flaps). None had collection, haematoma, infection or recurrence. Complete eccentric excision and partial obliteration of the natal cleft using various adipofascio-cutaneous flaps ensured reliable wound healing with fewer dressings and morbidity, shortened hospital stay and early resumption of work, good cosmesis and prevention of early and late recurrence. The lateral advancement flap is a viable option in the treatment of chronic pilonidal sinus.
