Summary
The Karydakis operation effectively treats postanal pilonidal sinus with a low recurrence rate. This surgical technique lateralizes the suture line, reducing the risk of hair penetration and subsequent sinus formation.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
Background:
- Postanal pilonidal sinus is a chronic condition often requiring surgical intervention.
- Recurrence and healing complications are significant challenges in managing this condition.
Purpose of the Study:
- To evaluate the efficacy and recurrence rates of the Karydakis operation for postanal pilonidal sinus.
- To assess the success of the Karydakis operation in patients with prior treatment failures.
Main Methods:
- A personal series of 141 patients with postanal pilonidal sinus underwent the Karydakis operation.
- Surgical technique involved total excision of the sinus with an eccentric elliptical excision and flap advancement.
- Follow-up was conducted for 1-108 months in 114 patients.
Main Results:
- An overall recurrence rate of 4% (5 patients) was observed, requiring further surgery.
- Of 33 referred patients with previous treatment failures, all were successfully cured.
- Long-term follow-up (over 18 months) was achieved in 69% of patients.
Conclusions:
- The Karydakis operation demonstrates a low recurrence rate for postanal pilonidal sinus.
- The technique's success is attributed to creating a shallow, lateralized midline wound less prone to hair penetration.
- This method offers a high cure rate, even in previously treated or failed cases.
