Cholecyst carcinoma

We report the rare case of an 80-year-old man with hepatocellular carcinoma that ruptured in the gallbladder, causing a cystic artery pseudoaneurysm and hemobilia. Emergency transarterial embolization (TAE) successfully controlled the bleeding without causing ischemic cholecystitis. Cone-beam computed tomography angiography was useful in identifying the bleeding branch of the selectively embolized cystic artery. Although the patient had poor liver function (Child-Pugh class C) before TAE, it remarkably improved after embolization due to the resolution of coagulopathy and obstructive jaundice caused by hemobilia...

PURPOSE: Acute cholecystitis is a complication of transarterial chemoembolization (TACE) that occasionally requires surgical intervention. We aimed to analyze the incidence and risk factors of cholecystitis requiring surgical intervention in patients with embolic material uptake on cone beam CT (CBCT) performed immediately after various TACE procedures. MATERIALS AND METHODS: After a retrospective review of 2633 TACE procedures performed over a 6-year period, 120 patients with embolic material retention in the gallbladder wall on CBCT immediately after TACE were selected...

This study reviews the spectrum of imaging findings and complications after transarterial chemoembolization (TACE) for the treatment of primary liver tumors (hepatocellular carcinoma, cholangiocarcinoma) and liver metastases. The review encompasses a spectrum of imaging criteria for assessing treatment response, including the modified Response Evaluation Criteria in Solid Tumors guidelines, tumor enhancement, and apparent diffusion coefficient alterations.We discuss the expected posttreatment changes and imaging responses to TACE, describing favorable and poor responses...

Gallbladder carcinoma (GBC) is a common malignancy and is usually diagnosed in the late stages of the disease. The identification of new effective early diagnostic biomarkers could represent an effective approach in reducing mortality in GBC. Altered expression of long non-coding RNAs (lncRNAs) is believed to be associated with the emergence and development of GBC. Our study aims to identify the expression of a range of circulating lncRNAs, including HOTAIR, ANRIL, H19, CCAT1 and MEG3, in matched serum and tissues of GBC for diagnosis and its association with clinicopathological features...

BACKGROUND: Xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC) share similar imaging and serological profiles, posing significant challenges in accurate preoperative diagnosis. This study aimed to identify reliable indicators and develop a predictive model to differentiate between XGC and GBC. METHODS: This retrospective study involved 436 patients from Zhejiang Provincial People's Hospital and The Affiliated Lihuili Hospital of Ningbo University...

Gallbladder carcinoma represents the most aggressive biliary tract cancer and the sixth most common gastrointestinal malignancy. The diagnosis is a challenging clinical task due to its clinical presentation, which is often non-specific, mimicking a heterogeneous group of diseases, as well as benign processes such as complicated cholecystitis, xanthogranulomatous cholecystitis, adenomyomatosis, porcelain gallbladder or metastasis to the gallbladder (most frequently derived from melanoma, renal cell carcinoma)...

Chyle leak is a rare but potentially morbid complication of abdominal surgery. There have been seven reported cases of chylous ascites following cholecystectomy, but no such occurrences are reported with percutaneous cholecystostomy tube (PCT) insertion. We report the case of a 67-year-old female with stage IVb recurrent uterine papillary serous carcinoma and extensive abdominal surgical history including a paraesophageal hernia repair, and a robotic hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, gastrocolic omentectomy, and hepatoduodenal lymphadenectomy...

Objectives: Pressure-Enabled Drug Delivery (PEDD), a method using pressure to advance catheter-delivered drug distribution, can improve treatment for hepatocellular carcinoma (HCC) and liver metastases, but real-world evidence is limited. We compared baseline patient characteristics, clinical complexity, and post-procedure healthcare resource utilization (HRUs) and clinical complications for PEDD and non-PEDD procedures. Methods: This study used a retrospective, longitudinal, cohort design of claims data from Clarivate's Real World Data Repository, which includes 98% of US payers with over 300 million unique patients from all US states...

INTRODUCTION: Mucin hypersecretion promoted by intestinal metaplasia can lead to gallstone formation. The presence of large amounts of mucin induced by a change in biliary epithelium structure is called a mucocele, a usually benign condition studied among animals but rarely described in humans. This entity must be distinguished from hydrops, a condition secondary to an impacted gallstone in the cystic duct leading to an outlet obstruction and distension of the gallbladder. PRESENTATION OF CASE: We report a case of a 51-year-old female with lithiasic cholecystitis showing areas of intestinal metaplasia associated with a mucocele...

Gallbladder (GB) disease is classified into two broad categories: GB wall-thickening and protuberant lesions, which include various lesions, such as adenomyomatosis, cholecystitis, GB polyps, and GB carcinoma. This review summarizes recent advances in the differential diagnosis of GB lesions, focusing primarily on endoscopic ultrasound (EUS) and related technologies. Fundamental B-mode EUS and contrast-enhanced harmonic EUS (CH-EUS) have been reported to be useful for the diagnosis of GB diseases because they can evaluate the thickening of the GB wall and protuberant lesions in detail...

OBJECTIVE: To study the spectrum and distribution of histopathological changes and evaluate immunohistochemistry markers p53 protein and Ki67 antigen in various lesions of gall bladder. MATERIALS AND METHODS: A total of 804 consecutive gall bladder specimens were evaluated. Forty cases were selected for immunohistochemical analysis to evaluate expression of p53 and ki67 proliferation index, including 20 carcinoma gall bladder cases and 20 cases of inflammatory pathology associated with metaplasia, atypia, hyperplasia, dysplasia, and adenoma...

An 88-year-old woman had been diagnosed with hilar cholangiocarcinoma for 3 years since she received metallic stents for malignant biliary obstruction, and observed without any aggressive medical treatment. She was admitted to our hospital for further investigation of her abdominal pain. Abdominal CT showed an enlarged gallbladder, fluid collection in the right paracolic gutter, and swollen appendix. Laboratory tests showed high-grade inflammation. She was diagnosed with acute perforated appendicitis with acute cholecystitis...

The patient described herein was diagnosed with left breast, endometrial, and early gastric cancers at 49, 53, and 57 years of age, respectively. Magnetic resonance cholangiopancreatography performed when she was undergoing treatment for cholecystitis at 50 years of age showed local pancreatic duct dilatation in the pancreatic head. She was followed in the Department of Gastroenterology at our hospital for an intraductal papillary mucinous neoplasm(IPMN). An abdominal computed tomography scan obtained at 59 years of age revealed dilation of the main pancreatic duct in the pancreas body and tail, therefore an endoscopic ultrasound-guided fine needle aspiration was performed...

All three patients were female, one in her 50s, and the other two in their 60s. The one in her 50s had liver metastasis and the other two had unresectable advanced cholecystic carcinomas with peritoneal dissemination. All three received 8-12 courses of gemcitabine plus CDDP(GC). After GC, all three were deemed to be candidates for R0 resection and underwent resection of two central liver segments. In addition, the second patient required an extrahepatic cholangiectomy; an extended cholecystectomy, plus an extrahepatic cholangiectomy, plus a complete omental resection; and the third needed an extended cholecystectomy, plus an extrahepatic cholangiectomy with a partial transverse colon resection, plus a partial duodenectomy...

Xanthogranulomatous cholecystitis (XGC) is one of the rare variants of chronic cholecystitis which is characterized by inflammation of gall bladder along with infiltration by acute and chronic inflammatory cells. Intramural accumulation of lipid laden macrophages in GB wall is the hallmark of the disease. XGC results in dense adhesion of gall bladder (GB) to surrounding structures, like duodenum, colon, and stomach. The intense GB inflammation results in gall bladder perforation and development of fistulous communication between gall bladder and surrounding structures...

An ectopic hepatocellular carcinoma (HCC) that originates from the ectopic liver is defined as a hepatic organ or tissue not conventionally linked to surrounding tissues. Ectopic HCC has a rare clinical incidence, and diagnosing it before surgery is challenging. Its characteristics and biological behavior have not been fully elucidated. This report presents a unique case of ectopic HCC in the gallbladder, discontinuous with the liver. A 74-year-old man was referred to our hospital after primarily complaining of fever and right hypochondrium pain...

Mutation detection for therapy monitoring in cell-free DNA (cfDNA) is used clinically for some malignancies. Gallbladder carcinoma (GBC) presents a diagnostic challenge and has limited late-stage treatment options. To our knowledge, this novel study examines, for the first time, genomic alterations in cfDNA from GBC to assess diagnostic accuracy and therapeutic options. The concordance of somatic genomic changes in cfDNA and DNA from paired tumor tissue was analyzed. Paired serum and tissue samples from 40 histologically proven GBC, 20 cholecystitis, and 4 normal (noninflamed gallbladder) controls were included...

The distinction between Xanthogranulomatous Cholecystitis (XGC) and Gallbladder Carcinoma (GBC) is challenging due to their similar imaging features. This study aimed to differentiate between XGC and GBC using a deep learning nomogram model built from contrast enhanced computed tomography (CT) scans. 297 patients were included with confirmed XGC (94) and GBC (203) as the training and internal validation cohort from 2017 to 2021. The deep learning model Resnet-18 with Fourier transformation named FCovResnet18, shows most impressive potential in distinguishing XGC from GBC using 3-phase merged images...

BACKGROUND: Observational research has shed light on the ability of gut microbes to influence the onset and progression of gastrointestinal diseases. The causal relationships between specific gut microbiomes and various gastrointestinal conditions, however, remain unknown. METHODS: We investigated the relationship between gut microbiota and seven specific gastrointestinal disorders using a robust two-sample Mendelian randomization (MR) approach. The inverse variance-weighted (IVW) method was used as the primary analysis tool in our study...
