Abstract
A minimally invasive (MI) approach using small incisions and vessel loops for drainage of simple perianal abscesses has been described in the pediatric population with decreased postoperative pain and comparable results to the traditional incision and drainage (I&D). The hypothesis was MI I&D will yield similar outcomes in adults. Patients who underwent I&D of perianal abscesses at an urban hospital from January 2008 to December 2015 were identified by Current Procedural Terminology code. Patients below 18 years of age, with inflammatory bowel diseases, or fistulae were excluded. Recurrences, readmissions, operative time, length of stay, complications, and costs were compared. There were 47 traditional and 96 MI I&D with no significant differences in demographics, average body mass index, and abscess size. No significant differences were noted in recurrences, readmissions, length of stay, operative time, or costs (P > 0.05). Postoperative complications occurred more frequently in the traditional group (P < 0.01) with a lower rate of follow-up (P < 0.05). MI I&D for simple anal abscesses in adults is associated with better compliance and fewer complications than the traditional approach. Although further studies are needed to determine if MI I&D confers superiority, this approach should be considered as first-line treatment for uncomplicated perirectal abscesses in adults.
