Summary
Endorectal ultrasound effectively identified perirectal lesions in 9.3% of patients, aiding in diagnosis. This imaging technique offers high resolution for assessing pararectal disease and guiding biopsies.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Perirectal lesions require accurate diagnosis for effective management.
- Endorectal ultrasound (ERUS) is an emerging imaging modality for evaluating the perirectal region.
Observation:
- A study examined 258 patients using ERUS between July 1992 and December 1993.
- 27 perirectal lesions were identified in 24 patients (9.3%), including abscesses, cysts, malignancies, and benign tumors.
- Histological and/or microbiological examination confirmed the nature of most lesions.
Findings:
- ERUS demonstrated high accuracy (89%) in assessing lesion size, location, and anatomical structure.
- Ultrasound-guided transrectal aspiration biopsy was successfully performed in six patients.
- ERUS showed potential superiority over CT and MRI due to its high resolution.
Implications:
- ERUS is a valuable complementary tool for diagnosing pararectal diseases.
- The high resolution of ERUS may surpass that of CT and MRI in specific applications.
- Ultrasound-guided aspiration biopsy enhances diagnostic capabilities and patient management.
