This descriptive study is based on detailed data of biliary tract cancer incidence in Slovakia in the period 1968-1977. Age-adjusted incidence rates of biliary tract cancer in the given decade decreased in females while in males they showed a slight increase. The study of geographic distribution revealed diminishing incidence rates from west to the east in both sexes with extremely elevated rates in towns and suburban districts in males. Different shapes of age-specific incidence curves together with the identified histological types suggested different epidemiological characteristics of individual subsites within this site. Relatively high incidence rates of biliary tract cancer in Slovakia as well as in whole Czechoslovakia, in comparison with other countries or areas of Europe, could be related to the excessive prevalence of gallstones and high number of surgical interventions upon biliary tract in this country while the decreasing incidence rates in women coincided with elevated number of cholecystectomies. The significance of detailed descriptive data from cancer registries for further analytic and etiologic study of biliary tract cancer according to subsites for a better delimitation of high risk groups and primary prevention strategies is stressed.

Biliary signet-ring cell carcinoma is a rare malignant tumor of the biliary tract. signet-ring cell carcinoma often occurs in the gastrointestinal tract. In this case, we can intuitively see the location, shape and scope of the tumor through endoscopic ultrasonography (EUS) combined with a peroral direct choledochoscope.

Background: Malignant obstructive jaundice (MOJ) is characterized by the presence of malignant tumors infiltrating or compressing the bile duct, causing poor bile drainage, generalized yellowing, pain, itching, and malaise. MOJ is burdensome for both the society and the families of affected patients and should be taken seriously.
Aim: To evaluate the clinical effect of stent placement during endoscopic retrograde cholangiopancreatography for relieving MOJ and the efficacy of percutaneous transhepatic biliary drainage in terms of liver function improvement, complication rates, and long-term patient outcomes.

Purpose: This work described a new species of Ceratomyxa, based on morphological and phylogenetic analyzes of myxospores collected from the gallbladder of the fish Astyanax mexicanus.
Methods: Sixty-two specimens were captured, between December 2022 and February 2024, in the Flexal River, in the community of Tessalônica, state of Amapá. The specimens were transported alive to the Laboratory of Morphophysiology and Animal Health, at the State University of Amapá, where the studies were carried out.

Lymph node sampling with endoscopic ultrasound fine needle aspiration (EUS-FNA) may affect treatment options for biliary tract cancers. Our aim is to clarify its utility and clinical significance and the factors associated with FNA cytology positivity. Seventy-one consecutive patients with biliary tract cancer who underwent EUS-FNA to diagnose lymphadenopathies from April 2012 to July 2021 were enrolled retrospectively.
