Diagnostic Value of Recto-perineal Ultrasound in Perianal Fistula

Diagnostic Value of Recto-perineal Ultrasound in Perianal Fistula; Pre Versus Intraoperative Findings: a Comparative Cross Section Study

Perianal fistula is a common anal problem. It needs only surgery. MRI is the best preoperative diagnostic tool, but it is demanding as it is expensive, time consuming and needs an experienced radiologist. So, we tried to find an alternative diagnostic tool which is cheaper, time saving and accurate and comparing its preoperative reports with intraoperative findings.

study was held in surgery department in Zagazig University Hospitals from September 2023 to March 2024. It included 93 patients with perianal fistula who were diagnosed clinically and radiological by trans recto-perineal ultrasound and comparing pre-operative ultrasound findings with intra-operative surgical findings.

Inclusion Criteria:

• Perianal abscess and\or fistula
• Patients who accidently discovered during transvaginal ultrasound.
• Age group between above 18 years old

Exclusion Criteria:

• Informed consent refusal.
• Proved anal malignancy.
• Patients less than 18 years old
