Adenomyomatosis of the Common Bile Duct and Ampulla of Vater.

GE Port J Gastroenterol 2021 Feb 2;28(2):121-133. Epub 2020 Sep 2.

Gastroenterology Department, Beatriz Ângelo Hospital, Loures, Portugal.

Adenomyomatosis is a rare benign lesion that has been observed in different sites throughout the gastrointestinal tract, most frequently in the gallbladder. Few cases have been described in the stomach, small bowel, bile ducts, and ampullary region. Adenomyomas of the vaterian system (ampulla and common bile duct) have important clinical consequences, since the majority of these lesions present with biliary tract obstruction and mimic malignant behavior.

A case of incidental infantile gallbladder adenomyomatosis: an unusual US finding of uncertain clinical significance.

J Ultrason 2021 18;20(83):e318-e321. Epub 2020 Dec 18.

Department of Social Medicine, School of Medicine, University of Crete, Greece.

Adenomyomatosis of the gallbladder is defined as hypertrophy of the gallbladder mucosal epithelium that invaginates into a thickened muscularis propria, leading to the formation of intramural diverticula. It is typically considered a benign condition most commonly affecting adults and, rarely, children. In this case report, we present a case of gallbladder adenomyomatosis in a 3-month-old infant.

Accuracy of Ultrasound in Diagnosing Gallbladder Polyps at a Community Hospital.

JSLS 2020 Oct-Dec;24(4)

Department of General Surgery, Danbury Hospital, Danbury CT.

Background And Objectives: Polyps are reported on 1-10% of routine transabdominal ultrasound studies of the gallbladder. Prior studies have reported poor sensitivity and specificity for this diagnostic modality at determining malignant potential of polyps. The aim of this study is to determine the incidence of gallbladder polyps documented on ultrasound at a community hospital, evaluate the congruency of ultrasound with final histopathology, and explore factors which may improve ultrasound accuracy at diagnosing true adenomatous polyps.

Benign gallbladder diseases: Imaging techniques and tips for differentiating with malignant gallbladder diseases.

World J Gastroenterol 2020 Jun;26(22):2967-2986

Department of Radiology, Konkuk University Medical Center, Konkuk University School of Medicine, 120-1 Neungdong-ro, Gwangjin-gu, Seoul 05030, South Korea.

Benign gallbladder diseases usually present with intraluminal lesions and localized or diffuse wall thickening. Intraluminal lesions of the gallbladder include gallstones, cholesterol polyps, adenomas, or sludge and polypoid type of gallbladder cancer must subsequently be excluded. Polyp size, stalk width, and enhancement intensity on contrast-enhanced ultrasound and degree of diffusion restriction may help differentiate cholesterol polyps and adenomas from gallbladder cancer.

B-mode ultrasonographic diagnosis in gallbladder wall thickening.

J Med Ultrason (2001) 2021 Apr 24;48(2):175-186. Epub 2020 Apr 24.

Department of Gastroenterology, Bantane Hospital, Fujita Health University School of Medicine, 3-6-10, Otobashi, Nakagawa-ku, Nagoya, 454-8509, Japan.

Diseases associated with gallbladder wall thickening include benign entities such as adenomyomatosis of the gallbladder, acute and chronic cholecystitis, and hyperplasia associated with pancreaticobiliary maljunction, and also cancer. Unique conditions such as sclerosing cholecystitis and cholecystitis associated with immune checkpoint inhibitor treatment can also manifest as wall thickening, as in some systemic inflammatory conditions. Gallbladder cancer, the most serious disease that can show wall thickening, can be difficult to diagnose early and to distinguish from benign causes of wall thickening, contributing to a poor prognosis.

Utility of multiple endoscopic techniques in differential diagnosis of gallbladder adenomyomatosis from gallbladder malignancy with bile duct invasion: A case report.

World J Clin Cases 2020 Jan;8(2):464-470

Department of Hepatopancreatobiliary Surgery, The First Hospital of Jilin University, Changchun 130021, Jilin Province, China.

Background: Gallbladder adenomyomatosis (GAM) is a benign lesion, characterized by thickening of the gallbladder wall and a focal mass, which overlap with the features of gallbladder malignancy. Consequently, differential diagnosis of GAM from gallbladder cancer is difficult and approximately 20% of suspected malignant biliary strictures are postoperatively confirmed as benign lesions. Herein, we report a case in which a preoperative diagnosis of GAM was made by a combination of endoscopic and imaging techniques. Read More

The major role of conventional ultrasonography (US) can be divided into three processes: cancer screening, differential diagnosis, and assessment of the depth of tumor invasion. As US is a simple and minimally invasive modality, it is widely used for cancer screening and health checkups. Both gallbladder (GB) polyps and thickened wall of the GB are common US findings.

Feasibility study for rapid near-infrared spectroscopic identification of different gallbladder diseases by direct analysis of bile juice.

Analyst 2019 Dec;144(24):7236-7241

Department of Chemistry and Research Institute for Convergence of Basic Science, Hanyang University, Seoul 04763, Republic of Korea.

A whole-sample-covering near-infrared (NIR) spectroscopy scheme has been adopted for the simple drop-and-dry measurement of raw bile juice for the identification of gallbladder (GB) diseases of stone, polyp, and cancer. For reproducible measurement, a non-NIR absorbing polytetrafluoroethylene (PTFE) providing a hydrophobic surface was chosen as a substrate to form bile juice droplets of a consistent shape. To ensure representative spectroscopic sampling, NIR radiation illuminated the whole area of the dried sample for spectral acquisition. Read More
