Background:
Omental biopsy has conventionally been performed using a surgical approach. USG-guided omental biopsy is a safe and effective alternative. The purpose of this study was to assess the utility of USG guidance for biopsy of the greater omentum.
Study Design:
Retrospective study.
Materials And Methods:
We retrospectively reviewed all omental biopsies performed under USG guidance from April 2006 to March 2010 in a tertiary care hospital.
Results:
One hundred and seventy-three patients were included. Out of these, 82 (47%) patients were diagnosed to have malignancies, 58 (34%) patients had granulomatous inflammation either suggestive of or consistent with tuberculosis, 29 (17%) patients were diagnosed to have inconclusive biopsy results, and 4 (2%) patients had an inadequate sample for histopathological examination. There were no major procedure-related complications.
Conclusion:
USG-guided biopsy of the omentum is a safe and effective procedure. A thickened omentum can serve as an easily accessible site for biopsy, especially in patients who have ascites of unknown etiology and in those with a history of previous malignancy.
