A Retrospective Study of Pilonidal Sinus Healing by Secondary Intention Using Negative Pressure Wound Therapy Versus Alginate or Gauze Dressings.

A Retrospective Study of Pilonidal Sinus Healing by Secondary Intention Using Negative Pressure Wound Therapy Versus Alginate or Gauze Dressings. Ostomy Wound Manage. 2017 Mar;63(3):47-53 Authors: Danne J, Gwini S, McKenzie D, Danne P Abstract Pilonidal sinus (PS) disease is an inflammatory skin and subcutaneous tissue condition that presents with infection, acute abscess, chronic discharging wounds, and/or pain. Surgery with open healing by secondary intention typically is used to achieve the fastest healing time with minimal recurrence rates. A retrospective analysis was conducted of data extracted from the medical records of 73 consecutive patients who had symptomatic natal cleft PS over a 10-year period to compare use of NPWT to alginate-based/gauze daily dressing (DD) changes in terms of healing time and recurrence. Variables extracted included age, gender, PS wound diameter (small <1 cm, medium 1 cm to 3 cm, large >3 cm), and time in weeks to achieving the endpoint (epithelialization). Risk factors examined that can affect healing or recurrence of previously operated PS disease included initial drainage before excision and risk factors for impaired healing (morbid obesity as determined by body mass index [BMI] ≥35, chronic infective skin conditions, and ongoing therapy with immuno-modulating drugs or chemotherapy), and loss to follow-up. Data were collected and analyzed using the chi-squared statistic, Kaplan-Meier curv...
