CT guided transgluteal fine needle aspiration biopsy

Area of Science:

• Radiology
• Oncology
• Surgical Pathology

Background:

• Local recurrence of rectal carcinoma after abdomino-perineal resection presents diagnostic challenges.
• Distinguishing recurrent disease from post-surgical changes in the presacral area is crucial for patient management.

Purpose of the Study:

• To assess the utility of computed tomography (CT) in evaluating local recurrence of rectal carcinoma.
• To determine the effectiveness of CT-guided fine needle aspiration biopsy (FNAB) for diagnosing presacral masses post-resection.

Main Methods:

• Computed tomography (CT) was employed to visualize the presacral area following abdomino-perineal resection.
• CT-guided fine needle aspiration biopsy (FNAB) utilized a transgluteal approach for tissue sampling.

Main Results:

• CT is a suitable imaging modality for detecting soft tissue masses in the presacral region.
• CT-guided FNAB provided cytological proof of the lesion's nature in 7 out of 9 patients, demonstrating a high success rate.

Conclusions:

• CT is a valuable tool for the evaluation of local recurrence of rectal carcinoma.
• CT-guided transgluteal FNAB is a relatively simple, fast, and effective procedure for obtaining cytological diagnoses of presacral lesions.
