Int J Surg Case Rep 2024; 120:109857. [PMID: 38852568 PMCID: PMC11193026 DOI: 10.1016/j.ijscr.2024.109857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2024] [Revised: 05/30/2024] [Accepted: 06/01/2024] [Indexed: 06/11/2024] Open
Abstract
INTRODUCTION Xanthogranulomatous Cholecystitis (XGC) is a rare inflammatory condition characterized by the presence of xanthogranulomas within the gallbladder wall, often mimicking gallbladder carcinoma (GBC). Diagnosis is challenging and may require biopsy. Once GBC is excluded, an open cholecystectomy is recommended, although laparoscopic cholecystectomy is increasingly being performed with great caution. This case report aims to evaluate clinical and radiological features, surgical outcomes, and treatment approaches for XGC. CASE PRESENTATION A 70-year-old patient presented with right hypochondrial pain and a palpable gallbladder. A CT scan revealed a distended lithiasic gallbladder with a thickened irregular wall and hepatic nodules. A hepatic MRI suggested xanthogranulomatous cholecystitis. A CT-guided biopsy of the liver nodule showed no signs of malignancy. An open cholecystectomy with a trans-cystic drain was performed. Histological examination confirmed chronic xanthogranulomatous cholecystitis. The patient was discharged on postoperative day 10. A clinical and radiological follow-up at 6 months postoperatively showed no abnormalities. CLINICAL DISCUSSION XGC presents diagnostic challenges due to its resemblance to GBC. Imaging aids in diagnosis, but biopsy may be necessary. Open cholecystectomy is the recommended surgical treatment due to excessive local inflammation and the risk of concomitant malignancy. CONCLUSION Managing XGC demands a holistic approach that integrates all clinical insights and mandates close collaboration among a multidisciplinary team of surgeons, radiologists, and pathologists. Further research is needed to refine diagnostic and therapeutic strategies for this rare condition, especially in geriatric patients.

Should we suspect gallbladder cancer if which CT finding is observed in patients with localized gallbladder wall thickening? Eur J Radiol 2024; 176:111505. [PMID: 38796886 DOI: 10.1016/j.ejrad.2024.111505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 05/01/2024] [Accepted: 05/12/2024] [Indexed: 05/29/2024]
Abstract
PURPOSE To identify high-risk computed tomography (CT) features for predicting gallbladder (GB) cancer in patients presenting with localized GB wall thickening. METHODS This retrospective analysis included 120 patients (mean age: 63.9 ± 10.0 years; 51 men) exhibiting localized GB wall thickening on CT scans obtained between January 2008 and May 2017. Two radiologists independently evaluated CT imaging features for predicting GB cancer. The diagnostic performance of significant imaging features and their combinations was evaluated. High-risk CT features ranked by accuracy were delineated for predicting GB cancer. RESULTS This study included 55 patients with GB cancer and 65 with benign GB conditions. The top-four most accurate CT imaging features for predicting GB cancer were identified: heterogeneously enhancing single layer or strongly enhancing thick inner layer; GB wall thickness > 6.5 mm; hyperenhancement on arterial phase; and absence of intramural small cystic lesions (accuracies of 90.0 %, 88.3 %, 85.0 %, and 85.0 %, respectively). The combination of any three high-risk features exhibited the highest accuracy (94.2 %). The presence of any high-risk feature yielded a sensitivity of 100 %, whereas that of all high-risk features indicated a specificity of 100 %. CONCLUSION CT imaging features, whether alone or in combination, could effectively and accurately predict GB cancer among patients with localized GB wall thickening. This finding holds significance in guiding decisions regarding further diagnostic tests and treatment planning.

Abstract
Gallbladder carcinoma (GBC) is one of most aggressive and lethal malignancies. Early diagnosis of GBC is crucial for determining appropriate treatment and improving chances of cure. Chemotherapy represents the main therapeutic regimen for unresectable GBC patients to inhibit tumor growth & metastasis. But, chemoresistance is the major cause of GBC recurrence. Thus, there is an urgent need to explore potentially non-invasive and point-of-care approaches to screen GBC and monitor their chemoresistance. Herein, we established an electrochemical cytosensor to specifically detect circulating tumor cells (CTCs) and their chemoresistance. Trilayer of CdSe/ZnS quantum dots (QDs) were cladded upon SiO2 nanoparticles (NPs), forming Tri-QDs/PEI@SiO2 electrochemical probes. Upon conjugation of anti-ENPP1, the electrochemical probes were able to specifically label captured CTCs from GBC. The detection of CTCs and chemoresistance were realized by square wave anodic stripping voltammetric (SWASV) responses to anodic stripping current of Cd 2+ ion when cadmium in electrochemical probes was dissolved and eventually electrodeposited on bismuth film-modified glassy carbon electrode (BFE). Taking use of this cytosensor, one ensured the screening of GBC and limit of detection for CTCs approaches to ~10 cells/mL. Furthermore, by monitoring phenotypic changes of CTCs after drug treatment, the diagnosis of chemoresistance was achieved by our cytosensor.

Abstract
BACKGROUND Gallbladder cancer is the most common biliary tract malignancy. Reports from Africa suggest a low incidence of gallbladder cancer. Gallbladder cancer is most often diagnosed incidentally on pathology after cholecystectomy. The aim of this study was to determine the rate of incidental gallbladder cancer from cholecystectomy specimens in South Africa. METHODS An audit of cholecystectomies for suspected gallstone disease in South Africa was done by reviewing specimens processed by the South Africa National Health Laboratory Service from 2003 and 2015. To assess risk factors for the presence of malignancy, a case control comparison was done. Logistic regression was used to determine the association between risk factors and malignancy. Between-group comparisons of sex were carried out using Fisher exact test. Ages were compared using the independent samples t test. RESULTS Pathological analysis was conducted on 33,467 cholecystectomy specimens. The rate of incidental gallbladder cancer rate was 0.39% with no difference between gender (P = .19). The mean age of the incidental gallbladder cancer patients (61.8 years; SD 13.4 y) was significantly higher than that of patients without gallbladder cancer (47.2 years; SD 15.0) (P < .0001). The majority of patients presented with T2 and T3 tumors. On multivariate analysis, only age, the presence of acute inflammation, and dysplasia were associated with the presence of incidental gallbladder cancer. CONCLUSION This large African study demonstrates a high rate of incidental gallbladder cancer in a patient population that has previously been deemed at low risk for gallbladder malignancies.

Abstract
AIM To assess the value of the ratio of signal intensities at high and low b-values (b800/b0 ratio) during diffusion-weighted imaging (DWI) for gallbladder cancer diagnosis. MATERIALS AND METHODS All patients presenting with suspicious gallbladder lesions between January 2011 and December 2016 who underwent DWI and histopathological diagnoses of the lesions were assessed. RESULTS Thirty-two patients (24 men, eight women) were identified. Eighteen patients had benign gallbladder lesions while 14 had malignant lesions. The mean apparent diffusion coefficient (ADC) value was 1.62 (±0.57)×10-3 mm2/s for benign cases and 1.27 (±0.39)×10-3 mm2/s for malignant cases; this difference was not significant (p=0.0773). The mean b800/b0 ratio was 0.31 (±0.19) for benign cases and 0.48 (±0.13) for malignant cases; this difference was significant (p=0.007). The ROC curve for b800/b0 had an AUC of 0.782 (95% confidence interval [CI]: 0.616-0.947) with a sensitivity and specificity of 85.7% and 72.2%, respectively, at a cut-off point of 0.33. CONCLUSION The b800/b0 ratio can help differentiate benign and malignant gallbladder lesions and may be more reliable than ADC values in quantitative DWI assessments.

Abstract
Xanthogranulomatous cholecystitis (XGC) is a rare form of cholecystitis, characterized by the presence of xanthogranuloma, prominent yellow structures within the gallbladder wall that is very often lithiasic. When XGC presents in its pseudo-tumoral form with occasional adjacent organ involvement, it can mimic gallbladder carcinoma (GBC). The etiopathogenesis of XGC is inflammatory destruction of Rokitansky-Aschoff sinuses containing biliary and cholesterol pigments within the gallbladder wall; this leads to a florid granulomatous histiocytic inflammatory reaction. The prevalence ranges from 1.3% to 8.8% of all cholecystectomies and varies from country to country; XGC occurs predominantly in patients over 50 years of age, and is equally distributed between males and females. Its association with GBC remains a topic of debate in the literature (between 0 and 20%). Symptoms are non-specific and generally similar to those of acute or chronic cholecystitis. XGC, when associated with altered health status, leads to the suspicion of GBC. XGC can also come to light due to an acute complication of cholecystolithiasis, in particular, gallstone migration. Imaging by sonography and CT scan is suggestive, but magnetic resonance imaging is more specific. In difficult cases, biopsy may be necessary to eliminate the diagnosis of tumor. In case of pre- or intra-operative diagnostic doubt, the opinion of a hepatobiliary specialty center can be of help. When diagnosis of GBC has been eliminated, laparoscopic cholecystectomy is recommended, although with a high risk of conversion to laparotomy and complications.

Abstract
Gallbladder (GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal. Diffuse wall thickening is a secondary occurrence in both extrinsic and intrinsic pathologies of GB, whereas, focal wall thickening is mostly associated with intrinsic GB pathologies. In the absence of specific clinical features, accurate etiological diagnosis can be challenging. The survival rate in GB carcinoma (GBC) can be improved if it is diagnosed at an early stage, especially when the tumor is confined to the wall. The pattern of wall thickening in GBC is often confused with benign diseases, especially chronic cholecystitis, xanthogranulomatous cholecystitis, and adenomyomatosis. Early recognition and differentiation of these conditions can improve the prognosis. In this minireview, the authors describe the patterns of abnormalities on various imaging modalities (conventional as well as advanced) for the diagnosis of GB wall thickening. This paper also illustrates an algorithmic approach for the etiological diagnosis of GB wall thickening and suggests a formatted reporting for GB wall abnormalities.

Abstract
AIM To investigate the value of contrast enhanced ultrasound with high resolution linear transducers (HF-CEUS) for differential diagnosis of focal fundal gallbladder (GB) wall thickening. METHODS A total of 32 patients with incidentally detected focal fundal GB wall thickening were included. After conventional B mode ultrasound (BMUS) examinations, HF-CEUS were performed with a 7.5-12 MHz 9L4 linear transducer (S2000 HELX OXANA unit, Siemens). Two radiologists independently reviewed the HF-CEUS enhancement patterns to determine the differential features between malignancy and benignity with a five-point confidence scale. The diagnostic accuracy of BMUS and HF-CEUS for GB wall thickening was compared. The final gold standard was surgery with histological examination. RESULTS Final diagnoses included GB adenocarcinoma (n = 16), adenomyomatosis (n = 12), Xanthogranulomatous (n = 2) and cholecystitis (n = 2). HF-CEUS features associated with GB adenocarcinoma including arterial phase inhomogeneous hyperenhancement, venous phase hypoenhancement and disruption of GB wall layer structure (P < 0.05). Two small (5 mm) liver metastasis were confirmed by HF-CEUS during the late phase liver sweep as hypoenhanced lesions. Nonenhanced Rokitansky-Aschoff sinuses were clearly observed in 83.3% focal adenomyomatosis. Overall sensitivity, specificity and accuracy for differentiation between malignant and benign focal fundal GB wall thickening of HF-CEUS and BMUS were 84.3% vs 53.1%, 90.6% vs 59.3% and 87.5% vs 56.2% (P < 0.005). CONCLUSIONS CEUS performed with high frequency linear transducers could be a useful alternative in the differential diagnosis of focal fundal GB wall thickening on conventional ultrasound.

Abstract
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. Localized gallbladder wall thickening is largely due to segmental or focal gallbladder adenomyomatosis, although infiltrative cancer may present similarly. Identification of Rokitansky-Aschoff sinuses is pivotal in diagnosing adenomyomatosis. The layered pattern, degree of enhancement, and integrity of the wall are imaging clues that help discriminate innocuous thickening from gallbladder cancer. High-resolution ultrasound is especially useful for analyzing the layering of gallbladder wall. A diffusely thickened wall is frequently seen in inflammatory processes of the gallbladder. Nevertheless, it is important to check for coexistent cancer in instances of acute cholecystitis. Ultrasound used alone is limited in evaluating complicated cholecystitis and often requires complementary computed tomography. In chronic cholecystitis, preservation of a two-layered wall and weak wall enhancement are diagnostic clues for excluding malignancy. Magnetic resonance imaging in conjunction with diffusion-weighted imaging helps to differentiate xathogranulomatous cholecystitis from gallbladder cancer by identifying the presence of fat and degree of diffusion restriction. Such distinctions require a familiarity with typical imaging features of various gallbladder diseases and an understanding of the roles that assorted imaging modalities play in gallbladder evaluations.

Abstract
AIM Thick-walled gallbladder is difficult to characterize on conventional imaging. 18F-FDG PET was used to differentiate benign and malignant wall thickness and compared with histopathology. METHODS Thirty patients with gallbladder (GB) wall thickening (focal > 4 mm and diffuse > 7 mm), underwents uspected on ultrasound, or CT scan, and underwent 18F-FDG PET. Histopathology of the specimen was compared with imaging findings. RESULTS The mean age was 48.22 ± 31.33 years with a M:F 1:4 ratio. Twenty patients had diffuse and 10 had focal thickening. On 18F-FDG PET, lesion was benign in 12, malignant in 13, and indeterminate in 5. Histopathology was malignancy in 12; benign in 18-chronic cholecystitis in 11, xanthogranulomatous in 4, IgG4 related in 2, and polyp in 1. The mean GB wall thickness was 7.79 ± 3.59 mm (10.34 malignant and 6.10 in benign, p = 0.001). At a cutoff of 8.5 mm, the sensitivity and specificity of detecting malignancy was 94% and 67%. The mean SUV uptake was 7.46 (benign 4.51, malignant 14.26, p = 0.0102). At a cutoff of 5.95, the sensitivity and specificity of detecting malignancy was 92% and 79%. For 18F-FDG PET, overall sensitivity was 91%, specificity 79%, PPV 77%, NPV 92%, and diagnostic accuracy was 84%. CONCLUSION 18F-FDG PET is a reliable method of differentiation between benign and malignant thickening of the gallbladder particularly when wall thickness and SUV value is taken into account.

Abstract
Xanthogranulomatous cholecystitis (XGC) is difficult to diagnose preoperatively because it often mimics gallbladder cancer. We present a case of a 64-year-old Caucasian male who presented with multiple intrahepatic abscesses, left portal vein and segmental right hepatic arterial thrombosis suspicious for extrahepatic cholangiocarcinoma who ultimately underwent an extended left hepatectomy and was noted to have XGC on final pathology. This case presents a new challenge in diagnosing XGC prior to final pathology results given the unique left portal vein, and later, right anterior portal vein thrombosis and occlusion. XGC should be in the differential diagnosis when diffuse gallbladder wall thickening is associated with involvement of biliary and vascular structures. While diagnosing these cases can be challenging, increased awareness of varied involvement of the liver and hilar structures associated with this diseases process may aid in the selection of the most appropriate surgical techniques.

Abstract
Upper abdominal pain, icterus and cholestasis are the symptoms leading to evaluation of the biliary tract. Together with its complications biliary stone disease is the main reason for inflammation of the biliary system. A distinction is made between acute and chronic variants. In chronic bile duct inflammation primary sclerosing cholangitis (PSC), primary biliary cirrhosis (PBC) and more recently IgG4-associated sclerosing cholangitis are of particular importance. Besides benign and tumor-like-lesions, malignant entities as gallbladder carcinoma and cholangiocarcinoma (CCC) in its three locations have to be mentioned. Despite all recent improvements, specificity of bile-tract imaging still remains limited, especially regarding malignant masses. Therefore the final diagnosis is made in many cases by histological analysis.
