Summary

A staging system was defined based on morphological extent of disease (stage I to stage IV for primary disease, and stage R for recurrent disease). Specific surgical technique was used for each stage. Demographics, perioperative data, short-term and long-term outcomes were evaluated according to the disease stage.

Conditions

  • Pilonidal Sinus

Interventions

PROCEDURE

pit-picking technique

midline pits were excised removing a minimal amount of tissue (with a margin of skin of \<1 mm). Incision of 1-2 cm in length was performed parallel to the most convenient side of the midline to be curetted of the chronic abscess cavity. All infected granulation tissue and hair were removed. After establishing hemostasis, the area of the excised midline pits was approximated by absorbable sutures.

PROCEDURE

Bascom Cleft Lift

The upper end of the incision was made 1-2 cm lateral to the midline on the more affected side and this was continued vertically over a distance of 1-2 mm from the midline pits. The lower end was fashioned from the midline in a V-shape in order to prevent a dog-ear deformity. The skin on this side of the natal cleft was then elevated and excised. The skin on the opposite side was undermined to the distance required to allow primary closure of the defect away from the midline without tension. Sinus tissue and its extensions were excised. The incision was then closed subcuticularly by absorbable polyglecaprone (3-0), after which a few interrupted mattress polyglecaprone (3-0) buttress sutures were also inserted.

PROCEDURE

Rhomboid excision with the Limberg Flap

The area to be excised was mapped on the skin in a rhomboid form, and the flap was designed. The skin incision was deepened to the postsacral fascia. The flap was fully mobilized and transposed medially to fill the defect without tension. The wound was closed in two layers: the subcutaneous tissue with absorbable (2/0 polyglactin) sutures and the skin with nonabsorbable (3/0 polypropylene) interrupted mattress suture

PROCEDURE

Other flap techniques

Bascom Cleft lift as described above, Rhomboid excision with the Limberg Flap as described above, V-Y advancement flap, Z-Plasty
