Computed tomography-guided percutaneous biopsy of abdominal lesions: indications, techniques, results, and complications

Abstract

ObjectiveTo evaluate the performance of computed tomography (CT)-guided percutaneous biopsy of abdominal lesions.Materials and MethodsThis retrospective, single-center study evaluated patients submitted to CT-guided percutaneous biopsy of abdominal lesions at a cancer center, between January 2014 and June 2015. The images and patient medical records were reviewed using a standardized data collection form.ResultsWe included 225 procedures performed in 212 patients, of whom 143 (63.5%) had a prior diagnosis of cancer. Of the 225 lesions biopsied, 88 (39.1%) had a suspected primary origin and 137 (60.9%) were suspected metastatic lesions. Complications occurred in only 14 (6.2%), the most common being self-limited bleeding, which occurred in 12 (85.7%) of the 14. The occurrence of complications was not found to be significantly associated with the lesion location, age of the patient, presence of comorbidities, use of a supplementary technique, vascularization pattern, or proximity of the lesion to large vessels. The pathology findings were sufficient for making the diagnosis in 202 cases (89.8%), and the diagnosis was consistent with the clinical suspicion in 132 (58.6%).ConclusionThe procedure demonstrated a high (approximately 90%) rate of providing a sufficient sample for the diagnosis and a low complication rate, the most common complication being self-limiting bleeding.

Percutaneous biopsy of retroperitoneal lesions - 10 year experience of a single centre

“…Recently published studies using improved methods declared both overall and subtyping accuracies exceeding 90-95% (ref. 5,17,20 ). These results approximate those of surgical excision biopsies.…”

“…Particular lymphomas however, form heterogenous masses of variable content which can relapse, transform or show decreased sensitivity to treatment. The retroperitoneum is not usually the location of the lymphoma origin, but in cases of relapse or transformation it is frequently affected 16,17 . Therefore, the locations with the largest amount of tissue increase or the most viable part of mass are the most suitable for the biopsy.…”

“…However, the differentiation purely on the basis of imaging examinations without histological verfication cannot be precise. The majority of retroperitoneal affections are Various articles can be found regarding retroperitoneal affections and particularly lymphomas using different imaging guidance, approaches and needle gauges 10,17,22 . The first published studies yielded ca.…”

Percutaneous transhepatic cholangiobiopsy

“…The results of fine-needle aspiration biopsy (FNAB) of the biliary system are inferior to those of FNAB of other sites (2) . Therefore, other techniques for obtaining histological samples have been developed for use in the biliary tract (3)(4)(5)(6)(7)(8)(9)(10) .…”

Pulmonary nodule localization guided by computed tomography using a nitinol guidewire before video-assisted thoracoscopic surgery

“…Image-guided puncture techniques are being used with increasing frequency in interventional radiology (1)(2)(3)(4) . The appropriate management of a pulmonary nodule usually requires a definitive pathological diagnosis.…”
