Clin Radiol 2021 Jul 12. Epub 2021 Jul 12.

Robin Phillips' Fistula Research Unit, St Mark's Hospital, Watford Road, Harrow HA1 3UJ, UK; Department of Surgery and Cancer, Imperial College London, London SW7 2AZ, UK. Electronic address:

Perianal fistulas affect approximately 2 in 10,000 people, causing symptoms such as pain and discharge, which can have a debilitating effect on a patient's quality of life. Surgical treatment, which can offer a potential cure or palliation of symptoms, must be considered carefully in cases with extensive sphincter involvement. In complex cases, the use of preoperative magnetic resonance imaging (MRI) can help to determine the best course of operative action. Read More

Antimicrobial photodynamic and photobiomodulation adjuvant therapies for the treatment of perianal abscess.

Photodiagnosis Photodyn Ther 2021 Jul 11;35:102437. Epub 2021 Jul 11.

Graduate Dentistry Program, Ibirapuera University. São Paulo, SP, Brazil.

Although the treatment and management options for perianal abscess vary considerably, most cases require incision and drainage. Whatever the clinical approach selected, it is imperative to monitor patients to identify postoperative signs and symptoms which suggest treatment failure or further complications, such as sepsis, recurrent abscess, and fistula formation. Considering the debate on the role of postoperative antibiotic therapy for patients with perianal abscess and the significant discomfort caused by the infection, the present study aimed to report a clinical case in which antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) were used after incision and drainage of a simple perianal abscess.
