A 40-year-old woman visited our hospital with a several-year history of right hypochondriac pain and vomiting after eating. She had been treated for functional dyspepsia, with no improvement in her symptoms. No gallstones were detected on imaging tests, but papillary insufficiency or dyskinesia of the gallbladder was suspected and biliary scintigraphy was performed. Biliary scintigraphy showed delayed excretion of radionuclides from the gallbladder and bile ducts into the duodenum. We initially suspected papillary dysfunction and performed endoscopic sphincterotomy, but there was no improvement in her symptoms. Biliary scintigraphy also showed delayed excretion of radionuclides, especially stagnation of radionuclides in the gallbladder. We suspected gallbladder dyskinesia and performed endoscopic gallbladder stenting, after which her symptoms disappeared and biliary scintigraphy showed improved excretion of radionuclides into the duodenum. Endoscopic gallbladder stenting may be useful for the diagnosis of gallbladder dyskinesia and for determining the efficacy of cholecystectomy.

From the Department of Radiology.
Purpose: To evaluate the predictive ability of 99mTc-galactosyl human serum albumin SPECT/CT quantitative parameters for posthepatectomy liver failure (PHLF).
Methods: Sixty-eight patients who underwent 99mTc-galactosyl human serum albumin scintigraphy as a preoperative examination for hepatectomy between July 2021 and December 2023 were prospectively evaluated. The patients were divided into PHLF and non-PHLF groups.

Hepatocellular carcinoma (HCC) and biliary tract cancers (BTC) pose significant diagnostic and therapeutic challenges. Magnetic resonance imaging (MRI) and multiphase computed tomography (CT) have been the preferred imaging modalities for diagnosis, staging, and surveillance of patients with these malignancies. The best clinical outcomes depend on the appropriate selection of treatment options from the tools available in neo-adjuvant therapy, surgical resection, locoregional therapy, liver transplantation, and adjuvant therapy.

Posttraumatic upper gastrointestinal bleeding (UGIB) is a very rare consequence of blunt liver trauma. It can be quite a diagnostic challenge for clinicians, as it can clinically manifest many weeks after the trauma or be scantily symptomatic. The following article would like to provide an analysis of clinical cases of 13 patients following blunt liver injuries, the main symptoms of which was bleeding into the gastrointestinal tract through the biliary tree.

The tumor microenvironment (TME) is a dynamic and complex medium that plays a central role in cancer progression, metastasis, and treatment resistance. Among the key elements of the TME, cancer-associated fibroblasts (CAFs) are particularly important for their ability to remodel the extracellular matrix, promote angiogenesis, and suppress anti-tumor immune responses. Fibroblast activation protein (FAP), predominantly expressed by CAFs, has emerged as a promising target in both cancer diagnostics and therapeutics.

Article Synopsis
- Biliary-enteric anastomosis (BEA) is a surgical procedure used for issues related to bile ducts and is crucial during liver transplants, with imaging playing a vital role in identifying complications.
- Various imaging techniques like ultrasound, CT, MRI, and nuclear scintigraphy provide different insights, with ultrasound enabling quick assessments and CT offering detailed anatomy.
- Common complications from BEA include bile leaks and strictures, and effective imaging is essential for their early detection and management, ultimately leading to better patient outcomes.
