Summary
The Karydakis flap (K-flap) procedure for sacrococcygeal pilonidal disease offers faster wound healing and return to work with fewer complications and recurrences compared to excision with healing by secondary intention (EHSI).
Area of Science:
- Surgical techniques
- Colorectal surgery
- Pilonidal disease management
Background:
- Sacrococcygeal pilonidal disease is commonly managed with Karydakis flap (K-flap) or excision with healing by secondary intention (EHSI).
- Comparative outcomes of these surgical methods require further investigation.
Purpose of the Study:
- To compare the early and late outcomes of K-flap versus EHSI for sacrococcygeal pilonidal disease.
- To evaluate wound healing time, return to work, complication rates, and recurrence between the two surgical techniques.
Main Methods:
- A prospective, randomized clinical trial involving 321 patients with sacrococcygeal pilonidal disease.
- Patients were randomized to either the Karydakis procedure or excision with healing by secondary intention.
- Outcomes assessed included wound healing duration, return to work, complications, and recurrence rates.
Main Results:
- The Karydakis flap group demonstrated significantly shorter wound healing times (16.44 days vs. 80.01 days) and faster return to work (14.44 days vs. 24.19 days).
- Lower rates of wound complications (18.7% vs. 31.2%) and recurrence (1.2% vs. 7.5%) were observed in the K-flap group.
- Excision with healing by secondary intention had a significantly shorter operation time (15.87 min vs. 55.17 min).
Conclusions:
- Both Karydakis flap and excision with healing by secondary intention are safe surgical options.
- The Karydakis flap is associated with superior outcomes, including reduced complications and recurrence, and improved healing and return to work timelines.
