Case Study: Chronic Pilonidal Sinus

Case Study Overview

Patient history

A 23-year-old female old female, with a non-healing pilonidal sinus of 5-year duration, present since the patient was 17 years old.

Despite four surgical interventions and other conventional dressing treatments over the years, the wound had never previously progressed to complete healing.​

The patient lived with her partner, worked within the legal system, and struggled with practice nurse appointments due to work commitments. She was unable to exercise and found socialising difficult due to pain from the wound and was in discomfort with dressings.

Initial assessment

The wound measured 50mm in length x 50mm in diameter. The wound was malodourous, causing distress for this young woman.

​The wound was critically colonised, bleeding easily. Wound bed was pale and devitalised.

High exudate levels were present and the ​surrounding tissue would become inflamed due to long term dressing use and was excoriated due to exposure to wound exudate.

Previous Treatment

Previous treatment included 4 surgical interventions for excision and drainage and one episode of wound suturing which failed.

Negative pressure wound therapy (NPWT) had also been attempted, alongside conventional dressings and long-term use of antibiotics.

NPWT had been unsuccessful due to struggling to maintain a dressing seal, and had resulted in over-granulation of the wound bed. 

Method

MaxioCel was commenced with treatment aims to achieve wound closure, reduce bacterial load and effects of critical colonisation, prevent bleeding and manage exudate levels.

The patient’s partner was taught to change MaxioCel on alternate days, to reduce bleeding and bacterial load and for patient comfort.

Results

MaxioCel’s haemostatic properties facilitated the opportunity for optimisation of wound healing by facilitating rapid haemostasis.

Medical images depict increased granulation and epithelisation from 10.07.23 to 21.09.23 with complete healing by 31.10.23.

The dressing managed fluctuating levels of exudate extremely well with no periwound maceration. Further future surgical intervention was avoided.

The patient was able to manage dressing changes at home with the support of her boyfriend, supporting patient self care.  

Conclusion

This case study demonstrates improved quality of life in this patient centred approach with patient engagement in both the evaluation and dressing decision-making progress.
