Contrast Media Mol Imaging 2022 6;2022:5459779. Epub 2022 May 6.

Department of Radiology, The Third Affiliated Hospital of Chongqing Medical University, Chongqing 401120, China.

To summarize the value of multislice spiral CT (MSCT) in the differential diagnosis of thick-wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), the clinical data of 36 patients with TWGC and 60 patients with chronic cholecystitis who were treated in our hospital from January 2017 to May 2021 were retrospectively analyzed, and the CT image features and diagnostic accuracy of the patients were summarized. Compared with the CC group, the proportions of disruption of gallbladder mucosa line, blurred gallbladder outline, high obstruction of biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, wall nodules, and the gallbladder wall thickness in the TWGC group were higher, with statistical significance ( < 0.05).

Feasibility of therapeutic endoscopic ultrasound in the bridge-to-surgery scenario: The example of pancreatic adenocarcinoma.

World J Gastroenterol 2022 Mar;28(10):976-984

Pancreatobiliary Endoscopy and EUS Division, Pancreas Translational & Clinical Research Center, IRCCS San Raffaele Scientific Institute, Vita-Salute San Raffaele University, Milan 20132, Italy.

Upfront resection is becoming a rarer indication for pancreatic ductal adenocarcinoma, as biologic behavior and natural history of the disease has boosted indications for neoadjuvant treatments. Jaundice, gastric outlet obstruction and acute cholecystitis can frequently complicate this window of opportunity, resulting in potentially deleterious chemotherapy discontinuation, whose resumption relies on effective, prompt and long-lasting management of these complications. Although therapeutic endoscopic ultrasound (t-EUS) can potentially offer some advantages over comparators, its use in potentially resectable patients is primal and has unfairly been restricted for fear of potential technical difficulties during subsequent surgery.

Clin J Gastroenterol 2022 Jun 25;15(3):630-634. Epub 2022 Mar 25.

Department of Digestive Surgery, Fukui Prefecture Saiseikai Hospital, Fukui, Japan.

Recently, "polypoid invasive carcinoma (PICA)" showing grossly visible polypoid, invasive carcinoma with no adenoma component was proposed as a neoplastic polyp of the gallbladder. Herein, we report four cases of PICA of the bile duct. PICA cases of bile duct showed single, sessile polypoid growth grossly, and polypoid components were composed of invasive carcinoma of papillary/tubular patterns with active desmoplasia, and invaded directly and continuously into the bile duct wall and periductal tissue.

Curr Health Sci J 2021 Jul-Sep;47(3):457-461. Epub 2021 Sep 30.

Department of Medicine: Hematology and Oncology, Augusta University, Augusta, GA, USA.

Clear cell renal cell carcinoma, accounts for approximately 70% of all adult renal tumors. This disease is well known for its high metastatic potential, with estimates of 25-50% of patients reporting metastasis to distant structures. However, there have only been several reported cases in medical literature describing hematogenous spread to the gallbladder, with the majority occurring metachronously, in males, and with multiple metastases.

Combination of portal vein embolization and neoadjuvant chemotherapy for locally advanced gallbladder cancer requiring extended hepatectomy - A novel approach.

Indian J Gastroenterol 2021 Dec 30;40(6):580-589. Epub 2021 Dec 30.

Department of Medical Oncology, Rajiv Gandhi Cancer Institute and Research Center, Sector -5, Rohini, New Delhi, 110 085, India.

Background: Locally advanced gallbladder cancer (GBC) may require extended hepatectomy. Portal vein embolization (PVE) can lead to hypertrophy of future liver remnant (FLR), and neoadjuvant chemotherapy (NACT) can be used in this cohort, with additional advantage of downstaging tumors as well as preventing progression while waiting for liver regeneration. Here, we share our experience of combining NACT along with PVE in locally advanced GBC requiring major hepatectomy. Read More

A Unique Presentation of Metastatic Gallbladder Carcinoma.

Case Rep Surg 2021 16;2021:6455540. Epub 2021 Dec 16.

Saint Louis University School of Medicine, USA.

Gallbladder carcinoma can be challenging to diagnose and treat and usually leads to poor outcome, due to its aggressive nature and the nonspecific clinical presentation at early stage. We describe an interesting case of a 60-year-old female who presented with stage 3 appendiceal carcinoma after appendectomy was performed outside hospital. Further imaging workup demonstrated enlarged ovarian cysts and porcelain gallbladder. Read More

Noninvasive preoperative differential diagnosis of gallbladder carcinoma and xanthogranulomatous cholecystitis: A retrospective cohort study of 240 patients.

Cancer Med 2022 01 27;11(1):176-182. Epub 2021 Nov 27.

Department of General Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Science & Peking Union Medical College, Beijing, China.

Background: Xanthogranulomatous cholecystitis (XGC) is an extremely rare entity. Due to XGC's clinical and radiological resemblance to gallbladder carcinoma (GBC), intraoperative frozen section during cholecystectomy is often performed to exclude the diagnosis of GBC. Our study is aiming to find a noninvasive indicator of XGC. Read More

Xanthogranulomatous cholecystitis on fusion of the planes of the liver.

Radiol Case Rep 2022 Jan 12;17(1):208-211. Epub 2021 Nov 12.

Department of Radiology, Avicenne Military Hospital, Marrakech, Morocco.

Xanthogranulomatous cholecystitis (CXG) is a rare entity of cholecystitis, characterized by the presence of xanthogranulomas within the gallbladder wall, that could be misdiagnosed as a vesicular carcinoma. We report a case of 66-year-old man with xanthogranulomatous cholecystitis associated with an incidental finding of a fusion of the planes of the liver which is a rare anatomic variant. Imaging especially ultrasounds, CT scan, and MRI play a key role in the characterization of those anomaly, thus avoiding a non-suitable surgical procedure. Read More
