Gallbladder cancer is the most common biliary tract cancer and the fifth most common cancer of the digestive system. However, the clinicopathologic features of gallbladder cancer in young Korean patients have not been studied. This study included 101 consecutive cases of gallbladder cancer that underwent cholecystectomy at Kangbuk Samsung Hospital from December 1990 to March 2011. The patients were divided into two groups by age at initial diagnosis of gallbladder cancer: a young patient group aged less than 45 years and an old patient group aged 45 or older...

Heterotopic gastric mucosa in the gallbladder is an unusual entity and is usually clinically silent. We report a 75-year-old female patient who presented with intermittent upper abdomial pain radiating to the back. Abdominal imaging studies showed a sessile polypoid lesion and a gallstone in the gallbladder. Gallbladder carcinoma was suspected and cholecystectomy performed. Intraoperative frozen section examination suggested mucinous tumor, suspicious for malignancy. However, the permanent sections revealed aberrant gastric tissue consisted of gastric pyloric and fundic glands of heterotopic gastric mucosa with intestinal metaplasia in the gallbladder...

BACKGROUND: Polypoid lesions of the gallbladder (PLG) are common, and most are benign. Few lesions are found to be malignant, but are not preoperatively distinguished as such using common imaging modalities. Therefore, we compared characteristics of benign and malignant PLGs in depth. METHODS: We enrolled 1204 consecutive patients diagnosed with PLG at Taipei Veterans General Hospital between January 2004 and December 2013. Patients underwent either surgery or regular follow-up with various imaging modalities for at least 24 months...

Chylous ascites is a very rare occurrence in a patient with gallbladder cancer (GBC), and only six cases have been reported. We report here one such case in a 55-year-old lady who presented to us with upper abdominal pain for 6 months. A polypoidal gallbladder mass with minimal liver invasion but with multiple subcentimeter pericholedochal, common hepatic, mesenteric, and para-aortic lymph nodes was found on contrast-enhanced computed tomography scan. At laparotomy, the abdomen had milky fluid with engorged beaded lymphatics all over the small intestine...

Endoscopic ultrasound (EUS) has recently played an increasing role in the diagnosis of gallbladder diseases. This review aims to summarize the role of EUS in the diagnosis of gallbladder lesions. EUS provides high-resolution images that can improve the diagnosis of gallbladder polypoid lesions and microlithiasis, in addition to evaluating gallbladder thickness and staging of gallbladder carcinoma. Contrast-enhancing agents may be useful for the differential diagnosis of gallbladder lesions, but the evidence of their effectiveness is still limited and further studies are required in this area to establish its usefulness...

INTRODUCTION: Gallbladder polyps (GBPs) are a common incidental finding on ultrasound (US) examination. The malignant potential of GBPs is debated, and there is limited guidance on surveillance. This systematic review sought to assess the natural history of ultrasonographically diagnosed GBPs and their malignant potential. METHODS: The keywords: "Gallbladder" AND ("polyp" OR "polypoid lesion") were used to conduct a search in four reference libraries to identify studies which examined the natural history of GBPs diagnosed by US...

The patient, a 50-year-old man, had been followed up by a neurologist under the diagnosis of mitochondrial encephalomyopathy. A gallstone detected by abdominal ultrasonography (US) had been present for several years, but localized protrusions of the gallbladder wall were first seen at the fundus in May 1995. Endoscopic US after abdominal US showed several small protruding lesions with maximum diameters of about 7 mm. These lesions had irregular surfaces and low internal echogenicity. An external high echoic layer, which represented the subserosa of the gallbladder, was intact...

REVIEW
Kee-Taek Jang, Sangjeong Ahn
CONTEXT: -The identification of a precursor lesion is important to understanding the histopathologic and genetic alterations in carcinogenesis. There are a plethora of terminologies that describe precursor lesions of the pancreatobiliary tract, ampulla of Vater, and gallbladder. The current terminologies for precursor lesions may make it difficult to understand the tumor biology. Here, we propose the concept of tumoral and flat intraepithelial neoplasia to improve our understanding of precursor lesions of many epithelial organs, including the pancreatobiliary tract, ampulla of Vater, and gallbladder...

Adenomas of the gallbladder are uncommon benign epithelial neoplasms. Rarely, they can give rise to gallbladder cancer, which is the most common malignancy of the biliary tract, carrying a poor prognosis and decreased survival. Here we report the case histories of two patients, 40-year-old and 53-year-old males who presented with >1 cm gallbladder polyps, which were detected and confirmed using various imaging studies. Cholecystectomy was performed on both patients and the subsequent pathologic exam revealed 1...

Biliary adenomas that are usually found in surgically removed gallbladders are rare, but can also occur in the extrahepatic biliary tree. We present a case series of extrahepatic bile duct adenomas at our institution, along with a review of the literature. All three patients with extrahepatic biliary adenomas (two in the common bile ducts, one in the hepatic duct) were female with a mean age of 74 years. On initial presentation, none of the patients had obstructive jaundice but two of the three patients had symptoms of biliary origin...
