Abstract

BACKGROUND



  • Biliary tract cancer ranks as the second most common hepatobiliary malignancy after hepatocellular carcinoma.

  • The entire biliary tree, including the gallbladder, is lined with simple columnar epithelium. When this epithelium undergoes malignant transformation, it most commonly results in adenocarcinomas.

  • Clinical history, geographic background, risk factors, patient’s age and gender are often crucial for arriving at diagnosis of these tumors.

  • Multimodality imaging plays a deep and integral role in the management of malignancies of the biliary tract.


MATERIAL AND METHODS



  • This study involved 50 patients with suspected biliary tract malignancy, conducted from January 2024 to September 2024. The study group consisted of mainly patients from different parts of Gujarat, neighbouring states of Rajasthan and Madhya Pradesh.

  • The research was carried out in the Department of Radiology at Gujarat Cancer Research Hospital and BJ Medical College in Asarva, Ahmedabad.


 


RESULTS:



  • In my study, gallbladder cancer was found to be more prevalent (52%) than cholangiocarcinoma (26%) and periampullary carcinoma (22%) among all types of biliary tract malignancies.

  • In my study, mass replacing gall bladder (11 patients, 42%) and gall bladder wall thickening(13patients, 50%)wereequallyprevalentingall bladdertumors.

  • periductal infiltrating type was found to be the most common radiological feature of hilar cholangiocarcinoma on both USG and CT.

  • In my study, all patients exhibited a dilated common bile duct and main pancreatic duct, known as the double duct sign. Periampullary lesions, either as intraluminal masses or wall thickening, were visualized in 73% (8 out of 11) of the patients.


CONCLUSION



  • USG scored slightly better over CT in cases of mild wall thickenings of gall bladder for detecting and differentiating them from benign gall bladder wall lesions. However,CTwas more sensitive in detection of infiltration of lesions in adjacent liver.

  • Among hilar and extrahepatic cholangiocarcinoma, USG was less sensitive than CT for detection of primary tumor.For detection of biliary tract dilatation, USG and CT were equally sensitive.

  • CT was highly sensitive in detecting metastatic lesions in different regions of body.
