Abstract
Purpose
The purpose was to assess the technique, technical success rate, and diagnostic value
of image-guided percutaneous biopsy of omental, peritoneal, and mesenteric lesions.
Materials and Methods
This was a combined prospective and retrospective study conducted at our center from
January 2019 to April 2021. Retrospective data were obtained by retrospective review
of the institutional database from January 2017 to January 2019. For the prospective
data, all patients referred to the interventional radiology department for image-guided
peritoneal, omental, or mesenteric biopsy during the study period were included in
the study. Patients not willing to participate in the study, cases lost to follow-up,
and those in whom imaging data could not be retrieved in the picture archiving and
communication system were excluded from the study. A total of 207 patients who underwent
computed tomography-guided biopsies were the final study cohort, including 134 prospective
cases and 73 retrospective cases. Various technical aspects, like technical success
rate, diagnostic yield, and diagnostic performance of the procedure, were calculated
and tabulated.
Results
The technical success rate and diagnostic yield of all biopsies were 100 and 98.06%,
respectively. The overall sensitivity, specificity, positive predictive value, and
negative predictive value of all biopsies to diagnose pathology were found to be 84.62,
91.46, 70.21, and 96.15%, respectively, while the accuracy to detect malignant pathology
was 90.15%.
Conclusion
The image-guided percutaneous biopsy of omental, mesenteric, and peritoneal lesions
has a high technical success rate and diagnostic yield irrespective of lesion size
and lesion depth.
