Postoperative Management with Wound Irrigation in Large Perianal Abscesses: A Case Series Study



Purpose. The present study aimed to assess the postoperative pain score, abscess recurrence rate, and fistula formation rate in patients with large perianal abscesses after undergoing incision and drainage with wound irrigation. Methods. We retrospectively analyzed patients who underwent incision and drainage with wound irrigation at Kaohsiung Veterans General Hospital between March 2016 and March 2019. We evaluated the abscess recurrence rate, fistula formation rate, postoperative admission duration, and postoperative pain score. Results. Nineteen patients underwent postoperative wound irrigation. The median postoperative admission duration was 7 days (interquartile range 17) (range, 2 to 59 days). The median postoperative day 1 pain score was 3/10 (range, 2/10 to 5/10). The rate of abscess recurrence was 21.1% (4/19) and the fistula formation rate was 15.8% (3/19). Conclusions. Management of perianal abscess using incision and drainage with wound irrigation may decrease postoperative discomfort; it is also relatively easy to care for the patient at their home. Moreover, it provides the benefits of low abscess recurrence and fistula formation rates.
