Ultrasound guided percutaneous biopsy of omentum: a safest technique to detect the causes of omental thickening

Junaid Iqbal, Nauman Al-Qamari, Amjad Sattar, Sadia Rashid


Background: The objective of our study was to determine the diagnostic value and safety of ultrasound guided percutaneous biopsy of omental thickening.

Methods: We prospectively analyzed 60 patients who underwent USG-guided omental biopsies in our institute from January 2016 to December 2016.

Results: Total 60 patients were included in our study. There were 40 (66.7%) female and 20 (33.3%) male patients. There were total 36 (60%) malignant cases, 20 (33.3%) chronic inflammation suggestive of TB while 4 (6.7%) were chronic peritoneal infection. Out of 36 malignant cases, majority 24 (66.7%) had ovarian cancer, 8 (22.2%) had endometrium cancer and 4 (11.1%) had large bowel cancer. Repeat biopsies were performed only in 4 (6.7%) cases.

Conclusions: Ultrasound-guided percutaneous biopsy of omentum is less expensive, safe and effective method with a high diagnostic accuracy.
