Background:
Prolonged packing of anorectal abscess cavities with internal dressings after incision and drainage is frequently used, but the efficacy of this practice remains controversial. Some studies highlight its use in hemostasis and preventing fistula and abscess recurrence, whereas others describe its economic burden and increase in pain. In this systematic review, we examine current evidence on the impact of packing after incision and drainage for anorectal abscesses.
Methods:
The medical librarian conducted a comprehensive literature search on January 5, 2023. We conducted the meta-analysis using RevMan 5.4.1 software with a Mantel-Haenszel random-effects model.
Results:
We identified 3 randomized controlled trials, comprising 490 patients. Of those, 241 patients (49%) received postoperative packing; most patients were male (n = 158, 65.6%), with a median age of 40.5 years and a follow-up of 6 months. Meta-analysis showed that prolonged wound packing was associated with delayed wound healing and increased pain, but no difference in abscess recurrence or fistula formation.
Conclusion:
In this systematic review of current evidence highlighting the impact of packing after incision and drainage for anorectal abscesses, we found that the practice is not associated with significant differences in abscess recurrence and fistula formation, but is associated with increased postoperative pain and delayed wound healing.
