“…Non-neoplastic cholangiopathies present imaging findings, signs, and symptoms that are similar and can also resemble those of other conditions, such as post-traumatic cholangiopathy (42) or even tumors of the biliary tract, in which case a histological study is necessary (43) . Only when the radiological, clinical, and epidemiological features of each of these entities are evaluated together we can narrow down the diagnostic possibilities and start treatment earlier.…”

Non-neoplastic cholangiopathies: an algorithmic approach

et al. 2020

Cholangiopathies are chronic diseases that affect the bile ducts, comprising a heterogeneous group of progressive and potentially fatal entities. The diagnosis of these diseases is a great challenge for radiologists because of the overlapping of their clinical, biochemical, and imaging findings. Nevertheless, identifying the precise etiology is crucial, given that the therapeutic options are distinct and influence the prognosis of the patient. The purpose of this review article is to discuss some of the non-neoplastic causes of cholangiopathies and to provide a useful diagnostic algorithm.

“…Image-guided biopsies have been evaluated in a number of recent articles in the radiology literature of Brazil (9)(10)(11)(12)(13)(14) . Ultrasound-guided percutaneous renal biopsy is established as a safe routine procedure, with a well-defined risk profile and a low complication rate (15) .…”

Ultrasound-guided percutaneous renal biopsy at a university hospital: retrospective analysis of success and complication rates

et al. 2021

Objective: To evaluate the success and complication rates of ultrasound-guided renal biopsy at a tertiary care hospital. Materials and Methods: This was a retrospective analysis of 97 ultrasound-guided renal biopsies, all performed by the same radiologist, between 1 March, 2017 and 31 October, 2019. Results: Of the 97 biopsies evaluated, 87 had a definitive pathological diagnosis. In five cases (5.4%), the biopsy results were inconclusive and a second procedure was required. In seven procedures (7.6%), there were complications, all of which were properly resolved. Conclusion: Ultrasound-guided renal biopsy has proven to be a safe, effective method for the diagnosis of nephropathies, with high success rates.

“…If there were lacerations or dehiscence of the biliary-enteric anastomosis, the catheter dwell time was extended to at least 30 days. In all cases, forceps biopsy of the stenotic area was performed before balloon dilation, as previously described ( 5 ) , to rule out malignancy.…”

Objective: To describe, assess the feasibility of, and quantify the long-term patency achieved with percutaneous transhepatic biliary dilation using the anastomotic biliary stricture (ABS) oversized balloon dilation technique as a single-step procedure for the treatment of benign anastomotic biliary strictures following hepatobiliary surgery. Materials and Methods: This was a retrospective, two-center study including 16 consecutive cases of symptomatic benign biliary-enteric strictures. After assessment of the diameter of the bile duct by computed tomography or magnetic resonance imaging, the strictures were dilated with oversized balloons (40-50% larger than the bile duct diameter) and an external biliary-enteric drain was placed. After drain removal, clinical symptoms and laboratory test results were evaluated every three months, whereas follow-up magnetic resonance imaging was performed at 30 days out and follow-up computed tomography was performed at 6 and 12 months out. Results: The mean follow-up time was 31.8 ± 8.15 months. Kaplan-Meier-estimated 1-, 2-, and 3-year patency rates were 88.2%, 82.4%, and 82.4%, respectively. There was one major complication—a small dehiscence of the anastomosis—which extended the catheter dwell time. Minor complications occurred in two cases—one small perihepatic hematoma and one segmental thrombosis of the left portal branch—neither of which required further intervention. Conclusion: The single-step ABS oversized balloon dilation technique is a feasible treatment for benign anastomotic biliary-enteric strictures. The technique appears to be associated with high rates of long-term clinical success and patency.
