Abstract
BACKGROUND The accurate characterization of gallbladder wall thickening (GWT) into benign or malignant on ultrasound (US) is a significant challenge. METHODS We searched the MEDLINE and EMBASE databases for studies reporting two-dimensional grayscale US in benign and malignant GWT. The pooled prevalence was calculated using a generalized linear mixed method with a random-effects model. The pooled sensitivity and specificity were calculated using a bivariate random-effects model. RESULTS Of the 7309 studies screened by titles, 73 studies with 18,008 patients were included. The most common findings in xanthogranulomatous cholecystitis (XGC) were lack of wall disruption and intramural hypoechoic nodules while adenomyomatosis (ADM) was frequently associated with intramural cysts and intramural echogenic foci. Echogenic foci, lack of gallbladder wall disruption, and hypoechoic nodules had a sensitivity of 89%, 77%, and 66% and specificity of 86%, 51%, and 80%, respectively for the diagnosis of benign GWT. Focal thickening and indistinct liver interface had a sensitivity of 75% and 55% and specificity of 64% and 69%, respectively for the diagnosis of malignant GWT. CONCLUSION intramural features (echogenic foci, hypoechoic nodules), gallbladder wall disruption, and liver interface are useful US features for the characterization of GWT.

Abstract
INTRODUCTION Gallbladder (GB) wall thickening is a relatively common finding on imaging. While there are clear recommendations for the management of gallstones, GB wall thickening presents a significant challenge. Despite advances in radiological as well as endoscopic techniques, the ability to characterize GB wall thickening is still limited. AREAS COVERED This review summarizes the currently available literature on various imaging investigations to characterize GB wall thickening. This review also summarizes the differences between benign and malignant GB wall thickening based on available imaging modalities. Transabdominal ultrasonography is the first-line investigation for evaluation of GB wall thickening. However, further characterization requires additional imaging tests. Magnetic resonance imaging (MRI) with the use of gadolinium and diffusion-weighted sequence is the preferred modality for GB wall characterization. EXPERT OPINION The accurate characterization of GB wall thickening is a challenging task. The available imaging criteria allow differentiation of benign and malignant GB wall thickening with moderate accuracy. The advanced imaging techniques, including contrast enhanced ultrasound, contrast-enhanced endoscopic ultrasound, and shear wave elastography, continue to evolve. There is a need for a well-designed reporting system for GB wall thickening to ensure uniformity of reporting of imaging tests, especially in regions with a high prevalence of GB cancer.

Abstract
Gallbladder occupying lesions are common diseases of biliary system. Among them, gallbladder cancer is difficult to diagnose due to the indistinguishable early symptoms, thus posing a great risk to the population. This study aims to establish a computed tomography (CT) prediction model for distinguishing benign and malignant lesions of gallbladder occupying lesions.The study included 211 patients with benign or malignant gallbladder occupying lesions who have taken resection in the Nanjing Drum Tower Hospital from January 2009 to December 2017. Clinical data collected includes age and sex; CT data includes tumor location, tumor maximum diameter, tumor form, venous phase portal venous CT value, abdominal aortic CT value, plain phase CT value, arterial phase CT value, venous phase CT value, delayed phase CT value, ΔCT1, ΔCT2, ΔCT3, ΔCT4, ΔCT5, ΔCT6, and ΔCT7. Calculation of odds ratio between benign and malignant gallbladder occupying lesions using single factor screening variables and multivariate logistic regression was done to establish a model and calculate the areas under receiver operating characteristic curves of the model.Multivariate logistic regression analysis showed that age, tumor maximum diameter, tumor form, venous phase portal venous CT value, ΔCT2, ΔCT4, and ΔCT6 are the main characteristic index for differential diagnosis of benign and malignant risk of gallbladder occupying lesions.Patients' age, tumor maximum diameter, tumor form, venous phase portal venous CT value, ΔCT2, ΔCT4, and ΔCT6 are independent risk factors for judging the benign and malignant of gallbladder occupying lesions. The model established exhibited a potential diagnostic value for distinguishing the malignant properties of gallbladder occupying lesions.

Abstract
BACKGROUND The purpose of this study was to systematically review and evaluate the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) in differentiating malignant and benign gallbladder lesions. METHODS We conducted a comprehensive search on PubMed, Embase, and Cochrane Library for all potential relevant articles published before December 2017. The pooled sensitivity, specificity, diagnostic odds ratio (DOR) and area under the curve (AUC) of summary receiver operating characteristic (SROC) were calculated by Meta-Disc Version 1.4 and STATA 12.0. RESULTS Twelve eligible studies were included in our study. A total of 1044 patients were assessed. The pooled sensitivity and specificity were 0.81 (95% confidence interval [CI], 0.77-0.84; inconsistency index [I] = 84.5%) and 0.87 (95% CI, 0.85-0.89; I = 94.4%), respectively. The pooled DOR was 58.84 (95% CI, 32.39-106.88; I = 51.9%). The AUC was 0.9371. According to Deek funnel plot asymmetry test, there was no significant publication bias (P = .31). CONCLUSIONS The results yielded from the available evidence suggest that CEUS is a promising and adjuvant imaging technique to conventional ultrasound for the differential diagnosis of benign and malignant gallbladder lesions.

Abstract
PURPOSE The aim of the retrospective study was to assess the diagnostic ultrasound (US) criteria for acute cholecystitis in patients admitted for symptomatic gallbladder stones. METHODS The medical records of 186 patients who had undergone cholecystectomy within 24 hours after an US examination were reviewed. Acute cholecystitis was defined on the basis of pathology findings. The correlation between standardized US signs and final diagnosis of acute cholecystitis was assessed with univariate and multivariate analyses. The diagnostic values of US based on the correlated signs were then calculated. RESULTS The prevalence of acute cholecystitis was 52.7% (95% confidence interval [CI], 42.8-64.2). Three US signs were found to be predictive of acute cholecystitis: gallbladder distension, wall edema, and pericholecystic fluid collection. When none of the US signs were registered, sonography proved to have a 72.4% (95% CI, 59.1-83.3) negative predictive value. When registering two or three signs, sonography had positive predictive values of 78% (95% CI, 56.3-92.5) and 100% (95% CI, 58.9-100), respectively. With just one sign, the positive predictive value was 57.6% (95% CI, 47.2-67.4), and such a finding was furthermore observed in only 53.2% of the cases. CONCLUSIONS The sonografic diagnosis of acute cholecystitis may be achieved by registering only three standardized US signs. Nevertheless, in patients admitted for symptomatic gallstones, US is of some utility in less than half of those patients.

Abstract
Cancer of the gallbladder, a rare entity with a poor prognosis, is often discovered incidentally during or after cholecystectomy. It tends to disseminate early via lymphatic, peritoneal, endobiliary, and hematogenous pathways. Diagnosis is made intra-operatively in only a quarter of cases, by examination of the opened cholecystectomy specimen in the operating room by the surgeon; this procedure should be routine. For incidentally-discovered cancers, survival was 28% at five years. Prognostic factors include age, TNM stage, gallbladder perforation during cholecystectomy and less-than-optimal resection at re-operation. Whether the laparoscopic route for the initial cholecystectomy has an impact on survival remains a subject of debate. R0 surgery is the only potentially curative treatment: simple cholecystectomy with clear margins is adequate resection for stage T1a tumors; extended cholecystectomy with lymphadenectomy and possibly resection of the bile duct is required for more advanced stages. After curative resection, neo-adjuvant or adjuvant chemotherapy and radiotherapy have not, so far, proven effective. Improvement of surgical practices (systematic review of cholecystectomy specimens in the OR, prevention of gallbladder perforation with bile spillage during surgery, early re-intervention for optimal resection) could improve the prognosis of these cancers.

Abstract
The value of contrast-enhanced ultrasound (CEUS) in differential diagnosis between benign and malignant gallbladder diseases was investigated. Thirty-three patients with gallbladder carcinomas and 47 with benign gallbladder diseases underwent CEUS. The lesion enhancement time, enhancement extent, pattern, dynamic change of enhancement and the intactness of gallbladder wall were evaluated. In the early phase at CEUS, hyper-, iso-, hypo-, and non-enhancement were found in 84.8% (28/33), 9.1% (3/33), 6.1% (2/33), and 0% (0/33) of gallbladder carcinomas, and 70.3% (33/47), 17.0% (8/47), 2.1% (1/47), and 10.6% (5/47) of benign diseases (p > 0.05). Hyper-enhancement or iso-enhancement in the early phase and then fading out to hypo-enhancement within 35 s after contrast agent administration was found in 90.9% (30/33) of carcinomas and 17.0% (8/47) of benign lesions (p < 0.001). Destruction of the gallbladder wall intactness was absent in benign diseases, whereas it was present in 28 (84.8%) of the 33 carcinomas (p < 0.001). Destruction of gallbladder wall intactness on CEUS yielded the highest capability in differential diagnosis, with sensitivity, specificity, and Youden's index of 84.8% (28/33), 100% (47/47), and 0.85, respectively. Conventional US made correct original diagnoses in 55 (68.8%) patients, whereas CEUS in 77 (96.3%). Thus, CEUS is useful in differential diagnosis between malignant and benign gallbladder diseases.

Abstract
PURPOSE The purpose of this study is to determine which computed tomography (CT) findings and clinical data can help to diagnose gallbladder perforation in acute cholecystitis. MATERIALS AND METHODS The medical records and CT findings of patients with surgically proven acute cholecystitis within the last recent 5 years were retrospectively reviewed and compared between 2 groups with and without gallbladder perforation. RESULTS A total of 75 patients with acute cholecystitis were included in the study, and 16 patients were proven to have gallbladder perforation. Higher mortality rate was found in the perforation group (18.8% vs 1.7%; P = .029). Older age (>70 years; P = .004) and higher percentage of segmented neutrophil (>80%; P = .027) were significant clinical factors for predicting gallbladder perforation in acute cholecystitis. The significant CT signs related to gallbladder perforation included visualized gallbladder wall defect (P = .000), intramural gas (P = .043), intraluminal gas (P = .000), intraluminal membrane (P = .043), pericholecystic abscess or biloma formation (P = .009), intraperitoneal free air (P = .001), and presence of ascites in the absence of hypoalbuminemia or other intraabdominal malignancy (P = .017). In multivariate analysis, visualized gallbladder wall defect was the most significant predicting CT feature for diagnosing gallbladder perforation in acute cholecystitis. CONCLUSION Elderly patients with higher segmented neutrophil and CT signs of gallbladder wall defect associated with acute cholecystitis may have high possibility of gallbladder rupture.

Abstract
BACKGROUND Gallbladder wall thickening (GWT) is often observed in patients with acute hepatitis (AH). However, little is known regarding the relationship between AH and GWT. We analyzed the characteristics of GWT in patients with AH. METHOD Between April 2002 and April 2007, 232 patients with AH underwent a sonographic examination. The clinical and laboratory findings of patients with GWT were evaluated and compared with patients without GWT. Data were recorded for the following variables: gender, age, laboratory findings, duration of symptom, presence of gallstone, and etiology of GWT. RESULTS A total of 147 (63%) patients with AH had GWT. GWT in patients with an alanine aminotransferase level more than 500 IU/l (5.2 +/- 3.4 mm) was greater than that in other patients (3.9 +/- 2.3 mm; p < 0.05). Hepatitis A virus infection (odds ratio = 3.17 [1.42-7.09]), female gender (odds ratio = 2.47 [1.34-4.56]), and an elevated total bilirubin level (odds ratio = 1.09 [1.03-1.15]) were positively associated with GWT. CONCLUSION The incidence of GWT in patients with AH was 63%, and there was an association with hepatitis A virus infection, female gender, and an elevated total bilirubin level.
