- W1970558698 abstract "A prospective study was performed to determine the frequency, type, and extent of abnormalities depicted with computed tomography (CT) after percutaneous biliary procedures (PBPs). Abdominal CT scans were obtained 24-72 hours after the PBP in 31 consecutive cases in 29 patients. Fifteen abnormalities were proved with CT in 14 patients (45%), as follows: subcapsular hematoma (two patients), subcapsular or perihepatic fluid collection (three patients), intrahepatic hematoma (three patients), nonspecific intrahepatic fluid collection (three patients), subcutaneous hematoma at the puncture site (one patient), free intraperitoneal air (one patient), intraperitoneal collection of contrast material (one patient), and inadvertent transxiphoid catheter tract (one patient). Only five of these patients had clinically apparent post-PBP complications that could be explained with CT findings. The 14 patients with positive CT findings required more needle passes (mean, 8.3 vs 4.6) during the PBP, had a difficult PBP more often (five patients [36%] vs four patients [27%]), and had more frequent placement of an internal-external drain (nine patients [64%]) than those with negative findings (eight patients [53%]). Positive findings on CT scans are common after a PBP and often are not associated with clinical symptoms." @default.
