Abstract
Gallbladder cancer is a common type of biliary tract tumor. Optimal management for early stage cases typically involves radical excision as the primary treatment modality. Various surgical techniques, including laparoscopic, robotic, and navigational surgery, have demonstrated favorable clinical outcomes in radical gallbladder excision. Unfortunately, most patients are ineligible for surgical intervention because of the advanced stage of the disease upon diagnosis. Consequently, non-surgical interventions, such as chemotherapy, radiotherapy, immunotherapy, and targeted therapy, have become the mainstay of treatment for patients in advanced stages. This review focuses on elucidating various surgical techniques as well as advancements in immunotherapy and targeted therapy in the context of recent advancements in gallbladder cancer research.

Abstract
Helicobacter pylori is a gram-negative pathogen commonly associated with peptic ulcer disease and gastric cancer. H. pylori infection has also been reported in cholelithiasis, cholecystitis, gallbladder polyps, and biliary tract cancers. However, the association between H. pylori and gallbladder and biliary tract pathologies remains unclear due to the paucity of literature. In response to the current literature gap, we aim to review and provide an updated summary of the association between H. pylori with gallbladder and biliary tract diseases and its impact on their clinical management. Relevant peer-reviewed studies were retrieved from Medline, PubMed, Embase, and Cochrane databases. We found that H. pylori infection was associated with cholelithiasis, chronic cholecystitis, biliary tract cancer, primary sclerosing cholangitis, and primary biliary cholangitis but not with gallbladder polyps. While causal links have been reported, prospective longitudinal studies are required to conclude the association between H. pylori and gallbladder pathologies. Clinicians should be aware of the implications that H. pylori infection has on the management of these diseases.

World J Surg Oncol 2023; 21:51.

Abstract
BACKGROUND The study aimed to explore the value of CT findings and inflammatory indicators in differentiating benign and malignant gallbladder polypoid lesions before surgery. METHODS The study comprised a total of 113 pathologically confirmed gallbladder polypoid lesions with a maximum diameter ≥ 1 cm (68 benign and 45 malignant), all of which were enhanced CT-scanned within 1 month before surgery. The CT findings and inflammatory indicators of the patients were analyzed by univariate and multivariate logistic regression analysis to identify independent predictors of gallbladder polypoid lesions, and then a nomogram distinguishing benign and malignant gallbladder polypoid lesions was developed by combining these characteristics. The receiver operating characteristic (ROC) curve and decision curve were plotted to assess the performance of the nomogram. RESULTS Base status of the lesion (p < 0.001), plain CT value (p < 0.001), neutrophil-lymphocyte ratio (NLR) (p = 0.041), and monocyte-lymphocyte ratio (MLR) (p = 0.022) were independent predictors of malignant polypoid lesions of the gallbladder. The nomogram model established by incorporating the above factors had good performance in differentiating and predicting benign and malignant gallbladder polypoid lesions (AUC = 0.964), with sensitivity and specificity of 82.4% and 97.8%, respectively. The DCA demonstrated the important clinical utility of our nomogram. CONCLUSION CT findings combined with inflammatory indicators can effectively differentiate benign and malignant gallbladder polypoid lesions before surgery, which is valuable for clinical decision-making.

Abstract
Incidental findings are commonly detected during examination of the gallbladder. Differentiating benign from malignant lesions is critical because of the poor prognosis associated with gallbladder malignancy. Therefore, it is important that radiologists and sonographers are aware of common incidental gallbladder findings, which undoubtedly will continue to increase with growing medical imaging use. Ultrasound is the primary imaging modality used to examine the gallbladder and biliary tree, but contrast-enhanced ultrasound and MRI are increasingly used. This review article focuses on two common incidental findings in the gallbladder; adenomyomatosis and gallbladder polyps. The imaging features of these conditions will be reviewed and compared between radiological modalities, and the pathology, epidemiology, natural history, and management will be discussed.

Abstract
The World Federation of Ultrasound in Medicine and Biology (WFUMB) is addressing the issue of incidental findings with a series of position papers to give advice on characterization and management. The biliary system (gallbladder and biliary tree) is the third most frequent site for incidental findings. This first part of the position paper on incidental findings of the biliary system is related to general aspects, gallbladder polyps and other incidental findings of the gallbladder wall. Available evidence on prevalence, diagnostic work-up, malignancy risk, follow-up and treatment is summarized with a special focus on ultrasound techniques. Multiparametric ultrasound features of gallbladder polyps and other incidentally detected gallbladder wall pathologies are described, and their inclusion in assessment of malignancy risk and decision- making on further management is suggested.

Risk of developing gallbladder cancer in patients with gallbladder polyps detected on transabdominal ultrasound: a systematic review and meta-analysis. Br J Radiol 2022; 95:20220152. [PMID: 35819918 PMCID: PMC10996949 DOI: 10.1259/bjr.20220152] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 06/14/2022] [Accepted: 07/06/2022] [Indexed: 01/30/2023] Open
Abstract
OBJECTIVE To estimate the risk of malignancy in gallbladder polyps of incremental sizes detected during transabdominal ultrasound (TAUS). METHODS We searched databases including MEDLINE, Embase, and Cochrane Library for eligible studies recording the polyp size from which gallbladder malignancy developed, confirmed following cholecystectomy, or by subsequent follow-up. Primary outcome was the risk of gallbladder cancer in patients with polyps. Secondary outcome was the effect of polyp size as a prognostic factor for cancer. Risk of bias was assessed using the Quality in Prognostic Factor Studies (QUIPS) tool. Bayesian meta-analysis estimated the median cancer risk according to polyp size. This study is registered with PROSPERO (CRD42020223629). RESULTS 82 studies published since 1990 reported primary data for 67,837 patients. 67,774 gallbladder polyps and 889 cancers were reported. The cumulative median cancer risk of a polyp measuring 10 mm or less was 0.60% (99% credible range 0.30-1.16%). Substantial heterogeneity existed between studies (I2 = 99.95%, 95% credible interval 99.86-99.98%). Risk of bias was generally high and overall confidence in evidence was low. 13 studies (15.6%) were graded with very low certainty, 56 studies (68.3%) with low certainty, and 13 studies (15.6%) with moderate certainty. In studies considered moderate quality, TAUS monitoring detected 4.6 cancers per 10,000 patients with polyps less than 10 mm. CONCLUSION Malignant risk in gallbladder polyps is low, particularly in polyps less than 10 mm, however the data are heterogenous and generally low quality. International guidelines, which have not previously modelled size data, should be informed by these findings. ADVANCES IN KNOWLEDGE This large systematic review and meta-analysis has shown that the mean cumulative risk of small gallbladder polyps is low, but heterogeneity and missing data in larger polyp sizes (>10 mm) means the risk is uncertain and may be higher than estimated.Studies considered to have better methodological quality suggest that previous estimates of risk are likely to be inflated.

Abstract
Gallbladder polyps (also known as polypoid lesions of the gallbladder) are a common incidental finding. The vast majority of gallbladder polyps smaller than 10 mm are not true neoplastic polyps but are benign cholesterol polyps with no inherent risk of malignancy. In addition, recent studies have shown that the overall risk of gallbladder cancer is not increased in patients with small gallbladder polyps, calling into question the rationale for frequent and prolonged follow-up of these common lesions. In 2021, a Society of Radiologists in Ultrasound, or SRU, consensus conference was convened to provide recommendations for the management of incidentally detected gallbladder polyps at US.

Longitudinal Ultrasound Assessment of Changes in Size and Number of Incidentally Detected Gallbladder Polyps. AJR Am J Roentgenol 2022; 218:472-483. [PMID: 34549608 DOI: 10.2214/ajr.21.26614] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/06/2023]
Abstract
BACKGROUND. Previous European multisociety guidelines recommend routine follow-up imaging of gallbladder polyps (including polyps < 6 mm in patients without risk factors) and cholecystectomy for polyp size changes of 2 mm or more. OBJECTIVE. The purpose of this study was to assess longitudinal changes in the number and size of gallbladder polyps on serial ultrasound examinations. METHODS. This retrospective study included patients who underwent at least one ultrasound examination between January 1, 2010, and December 31, 2020 (as part of a hepatocellular carcinoma screening and surveillance program) that showed a gallbladder polyp. Number of polyps and size of largest polyp were recorded based primarily on review of examination reports. Longitudinal changes on serial examinations were summarized. Pathologic findings from cholecystectomy were reviewed. RESULTS. Among 9683 patients, 759 (8%) had at least one ultrasound examination showing a polyp. Of these, 434 patients (248 men, 186 women; mean age, 50.6 years) had multiple examinations (range, 2-19 examinations; mean, 4.8 examinations per patient; mean interval between first and last examinations, 3.6 ± 3.1 [SD] years; maximum interval, 11.0 years). Among these 434 patients, 257 had one polyp, 40 had two polyps, and 137 had more than two polyps. Polyp size was 6 mm or less in 368 patients, 7-9 mm in 52 patients, and 10 mm or more in 14 patients. Number of polyps increased in 9% of patients, decreased in 14%, both increased and decreased on serial examinations in 22%, and showed no change in 55%. Polyp size increased in 10% of patients, decreased in 16%, both increased and decreased on serial examinations in 18%, and showed no change in 56%. In 9% of patients, gallbladder polyps were not detected on follow-up imaging; in 6% of patients, gallbladder polyps were not detected on a follow-up examination but were then detected on later studies. No gallbladder carcinoma was identified in 19 patients who underwent cholecystectomy. CONCLUSION. Gallbladder polyps fluctuate in size, number, and visibility over serial examinations. Using a 2-mm threshold for growth, 10% increased in size. No carcinoma was identified. CLINICAL IMPACT. European multisociety guidelines that propose surveillance of essentially all polyps and a 2-mm size change as the basis for cholecystectomy are likely too conservative for clinical application.

Abstract
INTRODUCTION Gallbladder adenomas have cancerous potential and occur in 4-8.9% of gallbladder polyps. The growth status (size progression and growth rate during follow-up) of polyps and their effectiveness for predicting adenomas are poorly defined. Herein, we compared adenomas and cholesterol polyps based on the growth status and evaluated the reported risk factors in predicting neoplasm. METHODS We enrolled 520 patients who underwent preoperative ultrasonic follow-up more than 6 months with post-cholecystectomy pathologically confirmed gallbladder polyps. The patients were classified into adenoma and cholesterol polyp groups. Growth status, clinical characteristics, laboratory data, ultrasonic findings were reviewed and compared between the groups. RESULTS Seventy-nine adenomas and 441 cholesterol polyps were analyzed. The mean diameter of adenomas (cholesterol polyps) was 7.24 ± 4.36 mm (6.23 ± 2.88 mm) in the initial and 12.06 ± 4.61 mm (10.05 ± 2.95 mm) in the preoperative examination. The median size progression (range) of polyps in the cholesterol polyps [3 (0, 22)] mm was smaller than that in adenomas [4 (0, 21)] mm (p = .075). The mean growth rate of adenomas (1.07 ± 1.33 mm/6 months) was slightly faster than in cholesterol polyps (0.83 ± 1.04 mm/6 months) (p = .338). The indicators significantly associated with adenomas were age >49.5 years, lack of gallbladder polyps/cholelithiasis family history, polyp size >11.5 mm and solitary polyp (p = .005, p = .027, p = .001, and p = .021, respectively). CONCLUSION Growth status was not a valuable modality to distinguishing gallbladder adenomas from cholesterol polyps. Risk factors such as age, polyp size, and solitary polyp were effective in predicting adenomas.

Prevalence and risk factors of gallbladder polyps in primary health care centers among patients examined by abdominal ultrasonography in Qatar: a case-control study. Qatar Med J 2021; 2021:48.

Abstract
BACKGROUND Gallbladder (GB) polyps are raised lesions from the GB wall and projected into its lumen. The prevalence of GB polyps ranged between 4.3% and 12.3%. The clinical presentation of GB polypoid lesions vary, can be nonspecific and vague, and may be asymptomatic. Identifying malignant and premalignant polyps is important to provide treatment early and prevent cancer spread or development of malignancy. Ultrasonography (US) is the first imaging modality widely used in abdominal imaging. It is a noninvasive, rapid, painless, and safe imaging technique, with no radiation; thus, it is considered the best available examination with good sensitivity and specificity for GB polyps. AIM OF THE WORK This study aimed to determine the relative frequency of the GB polyps and its risk factors among patients who underwent abdominal US in Primary Health Care Corporation, Qatar. MATERIALS AND METHODS This was quantitative multicenter observational case-control study nested in a cross-sectional design. For the cross-sectional top-level study, the first step was to assess available abdominal ultrasound studies for the presence of GB polyps and stones. The second step was to perform a case-control study with three groups (a case group and two control groups; first, participants without GB stones and GB polyps; second, patients with GB stones but without GB polyps). RESULTS The study evaluated the GB images of 7156 individuals. The overall prevalence of GB polyps was 7.4% in the study population. Specifically, the overall prevalence of solitary GB polyp was 4.2% and that of multiple GB polyps was 3.2%. Regarding the size distribution of GB polyps in positive cases, 89.4% were < 6 mm, 9.3% were 69 mm, and 1.3% were ≥ 10 mm. Prevalence rate of selected comorbidities were as follows: liver disease, 1.8%; diabetes mellitus, 25.5%; hypertension, 25.5%; and dyslipidemia, 29.8%. The prevalence in male and female patients was 7.7% and 7%, respectively. The prevalence of GB polyps was higher in south-eastern patients (21.4% of positive cases) and was the highest in the overweight group (8.8%). A higher prevalence was noted in the hypertensive group (hypertensive group, 9.8%; non-hypertensive group, 6.6%) and dyslipidemia group (dyslipidemia group, 7.8%; no dyslipidemia group, 7.2%). Moreover, a higher prevalence was noted in hepatitis B surface (HBS)-positive group (15%) than in the HBS-negative group (8.2%) and slightly higher in Helicobacter pylori antigen positive group than in the negative group. CONCLUSION Abdominal US is an important and commonly used imaging modality in the detection of GB polyps. In this study, the prevalence of GB polyps was approximately 7.4%, with higher prevalence in participants who were overweight and had diabetes mellitus, hypertension, and dyslipidemia.

Gallbladder Polyp Classification in Ultrasound Images Using an Ensemble Convolutional Neural Network Model. J Clin Med 2021; 10:jcm10163585.

Abstract
Differential diagnosis of true gallbladder polyps remains a challenging task. This study aimed to differentiate true polyps in ultrasound images using deep learning, especially gallbladder polyps less than 20 mm in size, where clinical distinction is necessary. A total of 501 patients with gallbladder polyp pathology confirmed through cholecystectomy were enrolled from two tertiary hospitals. Abdominal ultrasound images of gallbladder polyps from these patients were analyzed using an ensemble model combining three convolutional neural network (CNN) models and a 5-fold cross-validation. True polyp diagnosis with the ensemble model that learned only using ultrasonography images achieved an area under receiver operating characteristic curve (AUC) of 0.8960 and accuracy of 83.63%. After adding patient age and polyp size information, the diagnostic performance of the ensemble model improved, with a high specificity of 88.35%, AUC of 0.9082, and accuracy of 87.61%, outperforming the individual CNN models constituting the ensemble model. In the subgroup analysis, the ensemble model showed the best performance with AUC of 0.9131 for polyps larger than 10 mm. Our proposed ensemble model that combines three CNN models classifies gallbladder polyps of less than 20 mm in ultrasonography images with high accuracy and can be useful for avoiding unnecessary cholecystectomy with high specificity.

Abstract
A gallbladder (GB) polyp is an elevation of the GB mucosa that protrudes into the GB lumen. GB polyps have an estimated prevalence of 0.3-9.5% and can be divided into neoplastic (true) polyps and nonneoplastic polyps (pseudopolyps). Pseudopolyps are most commonly cholesterol polyps but also include focal adenomyomatosis and inflammatory polyps with no malignant potential. Neoplastic polyps, however, can be benign or malignant. Benign polyps are most commonly adenomas, while malignant polyps are usually adenocarcinoma. Transabdominal ultrasonography is the main radiological modality used for diagnosing and surveilling GB polyps. On the other hand, because it is difficult to diagnose GB polyps before surgery, alternative imaging modalities, such as endoscopic ultrasound, are being further evaluated. The current guidelines recommend cholecystectomy for GB polyps ≥ 10 mm in size as well as suboptimal sized GB polyps (6-9 mm) with other risk factors, including age >50, sessile, and symptoms. The quality of the evidence behind this practice is relatively low. Therefore, this review identifies the current gaps in the available evidence and guidelines and introduces methods that can help make decisions regarding patients who require a cholecystectomy or follow-up.

Abstract
• There was strong correlation between polyp diameter (≥ 10 mm vs <10 mm) and the risk of gallbladder cancer (OR=54; r=0.704). • There was moderate correlation between polyp diameter (10-19 mm vs <10 mm) and the risk of gallbladder cancer (OR=23; r=0.534). • There was moderate correlation between polyp diameter (≥ 20 mm vs <20 mm) and the risk of gallbladder cancer (OR=300; r=0.559). • There was moderate correlation between polyp diameter (≥ 20 mm vs <10 mm) and the risk of gallbladder cancer (OR=551; r=0.697). • Our results suggest that as the diameter of the polyp reaches 20 mm, it is necessary to plan a surgical treatment strategy as if the patient has gallbladder cancer.

Abstract
BACKGROUND Polypoid lesion of gallbladder (PLG) size larger than 10 mm is considered to be one of the surgical indications, but the final pathological results are mostly non-neoplastic polyps. The aim of the study was to define the risk factors to discriminate neoplastic PLG and create more precise criteria for surgical indications. METHODS A large scale, case-series study based on 2704 patients who underwent cholecystectomy for PLG was designed. Logistic regression analysis and receiver operating characteristic curve (ROC) was adopted to identify risk factors and the optimal size criteria for predicting neoplastic PLG. RESULTS Patients in the neoplastic group were significantly older than those in the non-neoplastic group and the average PLG size is much larger in the neoplastic group (18.5 ± 4.7 mm vs 12.6 ± 3.6 mm). Neoplastic PLGs are prone to be single and non-neoplastic polyps are usually multiple. On Multivariate logistic regression analysis, PLG size larger than 15 mm and age older than 43 years were found to be the independent risk factors to discriminate neoplastic PLG (Odds ratio 3.546 and 2.77 respectively). The ROC curve showed that 12 mm might be the more reasonable PLG size threshold for the surgical suggestion. CONCLUSIONS Considering its moderate diagnostic accuracy, the size of gallbladder polyp larger than 10 mm is insufficient to indicate surgical therapy for PLG and 12 mm should be the more optimal polyp's size threshold. Patients older than 43 years have a higher risk of having neoplastic polyps.

They are usually incidentally found during abdominal sonography or diagnosed on histopathology of a surgery specimen, with an estimated prevalence of up to 9.5% of patients. Gallbladder polyps are not mobile and do not demonstrate posterior acoustic shadowing; they may be sessile or pedunculated. Gallbladder polyps may be divided into pseudopolyps and true polyps. Pseudopolyps are benign and include cholesterolosis, cholesterinic polyps, inflammatory polyps, and localised adenomyomatosis. True gallbladder polyps can be benign or malignant. Benign polyps are most commonly adenomas, while malignant polyps are adenocarcinomas and metastases. There are also rare types of benign and malignant true gallbladder polyps, including mesenchymal tumours and lymphomas. Ultrasound is the first-choice imaging method for the diagnosis of gallbladder polyps, representing an indispensable tool for ensuring appropriate management. It enables limitation of secondary level investigations and avoidance of unnecessary cholecystectomies.

Abstract
Gallbladder polyps are an elevation of the mucous membrane that protrudes into the lumen of the gallbladder cavity. Their prevalence in the general population varies from 0.3 to 13.8%. According to the modern classification, polyps of the gallbladder are divided into benign non-tumor, benign tumor and malignant tumor polyps. A review of modern literature presents cohort and randomized controlled trials, including those summarized in meta-analyzes and systematic reviews, suggesting that the dominant form of polypoid formations of the gallbladder are cholesterol pseudo-polyps with no malignant potential associated with impaired cholesterol metabolism, often combined with gallbladder cholesterosis, metabolic syndrome and cardiovascular morbidity. Evidence is building up on the effectiveness of ursodeoxycholic acid for controlling components of the metabolic syndrome and cardiovascular risks. Ursodeoxycholic acid preparations may become promising for the management of cholesterol polyps.

Abstract
Background: Gallbladder lesions have become more common nowadays. But there is limited evidence-based guidance on surveillance of these patients for malignancy. Predicting malignancy could help clinicians better manage this condition and improve the prognosis. We evaluated the independent and joint effects of metabolic syndrome components on the risk of malignancy among patients with gallbladder lesions. Methods: Using a multicenter database, consecutive patients with pathologically confirmed gallbladder lesions between 2012 and 2019 were identified. Univariate and multivariate logistic regression analyses were used to evaluate the effects of metabolic syndrome components (diabetes, hypertension, dyslipidemia and obesity) as additive or combined indicators for the risk of malignancy. Unadjusted and adjusted odds ratios were calculated. Results: Of the 625 patients, 567 patients were identified with benign gallbladder lesions and 58 patients with gallbladder cancer (GBC). GBC group had less obesity but more dyslipidemia. Among all metabolic syndrome components, only dyslipidemia was significantly associated with GBC (odds ratio 2.674, 95% confidence interval 1.173-6.094). Dyslipidemia was an independent risk factor for malignancy (adjusted odds ratio 2.164, 95% confidence interval 1.165-4.021), regardless of whether the other risk factors and metabolic syndrome components were combined. Patients with decreased high-density lipoprotein had 3.035-fold higher risk of malignancy (adjusted odds ratio 3.035, 95% confidence interval 1.645-5.600). Conclusions: Dyslipidemia is associated with a 2.674-fold increase in the risk of malignancy in patients with gallbladder lesions. Dyslipidemia is an independent risk factor for malignancy, regardless of the presence of the other risk factors and metabolic syndrome components.

Abstract
OBJECTIVE To investigate the relationship between Helicobacter pylori (H. pylori) infection and gallstones or gallbladder polyps. METHODS This retrospective analysis included 27,881 individuals who underwent health examinations that included a H. pylori test and an abdominal ultrasound scan. Patients were divided into four groups: gallbladder polyp (P group), gallstone (S group), gallstone and gallbladder polyp (SP group), and no gallbladder disease (N group). Case-control matching was used to select the participants in the control group. RESULTS The mean ages of participants in the P, S, and SP groups were all significantly higher than the mean age of participants in the N group. The proportions of participants with each type of body mass index significantly differed between the N and P groups, and between the N and S groups. In total 45.7% of participants exhibited H. pylori infection. After case-control matching, the proportion of participants with H. pylori infection did not significantly differ according to the presence or absence of gallbladder polyps. Similar results were observed regarding gallstones, as well as gallstones and gallbladder polyps. CONCLUSION H. pylori infection might not be related to gallbladder polyps or gallstones.

Abstract
PURPOSE To develop and validate a novel method based on radiomics for the preoperative differentiation of benign and malignant gallbladder polypoid lesions (PLG). PATIENTS AND METHODS A total of 145 patients with pathological proven gallbladder polypoid lesions ≥ 1 cm were included in this retrospective study. All the patients underwent abdominal contrast-enhanced computed tomography (CT) examinations 3 weeks before cholecystectomy from January 2013 to January 2019. Seventy percent of the cases were randomly selected for the training dataset, and 30% of the cases were independently used for testing. Radiomics features extracted from portal venous-phase CT of the PLG and clinical features were analyzed, and the LASSO regression algorithm was used for data dimension reduction. Multivariable logistic regression was used to generate radiomics signatures, clinical signatures, and combination signatures. The receiver operating characteristic (ROC) curve and decision curve were plotted to assess the differentiating performance of the three signatures. RESULTS The area under the ROC curve (AUC) of the radiomics signature and clinical signature was 0.924 and 0.861 in the testing dataset, respectively. For the radiomics signature, the accuracy was 88.6%, with 88.0% specificity and 89.5% sensitivity. When combined, the AUC was 0.931, the specificity was 84.0%, and the sensitivity was 89.5%. The differences between the AUC values of the two sole models and the combination model were statistically nonsignificant. CONCLUSION Radiomics based on CT images can be helpful to differentiate benign and malignant gallbladder polyps ≥ 1 cm in size.

Abstract
Neoplastic gallbladder polyps (NGP) are rare; the prevalence in the overall population is less than 10%. NGP are associated with a risk of malignant degeneration and must be distinguished from other benign gallbladder polypoid lesions that occur more frequently. NGP are adenomas and the main risk associated with their management is to fail to detect their progression to gallbladder cancer, which is associated with a particular poor prognosis. The conclusions of the recent European recommendations have a low level of evidence, based essentially on retrospective small-volume studies. Abdominal sonography is the first line study for diagnosis and follow-up for NGP. To prevent the onset of gallbladder cancer, or treat malignant degeneration in its early phases, all NGP larger than 10mm, or symptomatic, or larger than 6mm with associated risk factors for cancer (age over 50, sessile polyp, Indian ethnicity, or patient with primary sclerosing cholangitis) are indications for cholecystectomy. Apart from these situations, simple sonographic surveillance is recommended for at least five years; if the NGP increases in size by more than 2mm in size, cholecystectomy is indicated. Laparoscopic cholecystectomy is possible but if the surgeon feels that the risk of intra-operative gallbladder perforation is high, conversion to laparotomy should be preferred to avoid potential intra-abdominal tumoral dissemination. When malignant NGP is suspected (size greater than 15mm, signs of locoregional extension on imaging), a comprehensive imaging workup should be performed to search for liver extension: in this setting, radical surgery should be considered.

Abstract
IMPORTANCE Gallbladder polyps (GP) are found in more than 4% of adult abdominal ultrasonographs. Their growth pattern and association with gallbladder cancer (GBC) are poorly defined. OBJECTIVE To determine the growth pattern of GPs and their association with GBC. DESIGN, SETTING, AND PARTICIPANTS This cohort study included 622 227 adult members (ie, aged 18 years or older) of Kaiser Permanente Northern California, an integrated health care delivery system, enrolled between January 1, 1995, and December 31, 2014. The GBC cohort comprised a total of 365 adults with GBC and prior ultrasonography, and the GP cohort comprised 35 970 adults with GPs present on ultrasonography. Data analysis was performed from March 2016 to November 2019. EXPOSURES Gallbladder polyps (quantitative size, <6 mm, 6 to <10 mm, and ≥10 mm or qualitative size [ie, tiny, small, moderate, and large]). MAIN OUTCOMES AND MEASURES For the GBC cohort, proportion of patients with GBC with polyps identified on preceding ultrasonograph. For the GP cohort, rates of GBC among those with polyps according to size and rate of GP growth of at least 2 mm over time. RESULTS The GBC cohort comprised 365 individuals (267 [73.1%] women; 173 [47.4%] white patients; median [interquartile range] age, 71 [61-79] years). After excluding 14 patients who did not have evaluation of polyp size, the final GP cohort comprised 35 856 adults, with 18 645 (52.0%) women, a median (interquartile range) age 50 (40-60) years, and 15 573 (43.3%) white patients. Gallbladder polyps were found in 22 patients (6.0%) in the GBC cohort and in 35 870 of 622 227 adults (5.8%) who underwent abdominal ultrasonography. Of these, 19 (0.053%) were diagnosed with GBC, similar to those without GP (316 of 586 357 [0.054%]). The unadjusted GBC rate per 100 000 person-years was 11.3 (95% CI, 6.2-16.3) overall and increased with polyp size, from 1.3 (95% CI, 0-4.0) with initial size of less than 6 mm (n = 17 531) to 128.2 (95% CI, 39.4-217.0) with initial size of 10 mm or larger (n = 2055). In those observed for at least 1 year, the rate was 3.6 (95% CI, 0.7-6.5) per 100 000 person-years. In 6359 patients with evaluable follow-up, unadjusted cumulative probabilities of polyp growth of at least 2 mm at 10 years were 66.2% (95% CI, 62.3%-70.0%) in polyps initially less than 6 mm and 52.9% (95% CI, 47.1%-59.0%) in polyps initially 6 mm to less than 10 mm. CONCLUSIONS AND RELEVANCE In this study, GBC rates were low and similar among patients with and without GPs. Growth of 2 mm or more appeared to be part of GP natural history. The results call into question the strategy of proactively following GP to detect GBC.

Abstract
BACKGROUND Gallbladder cancer is rare but associated with significant morbidity and mortality necessitating the early identification of premalignant and malignant lesions to improve overall prognosis. Despite limited evidence regarding the effectiveness of transabdominal ultrasound (US) in the detection of gallbladder polyps, it plays a key role in current European guidelines. The aim of this study was to investigate gallbladder polyp prevalence in a western European population and assess the diagnostic accuracy of transabdominal US. METHODS Data from patients who underwent cholecystectomy for US detected gallbladder polypoid lesions at four hospitals in Ireland and the United Kingdom between 2010 and 2018 were retrospectively collected. Patient demographics, ultrasonographic, and histopathologic findings were analyzed. RESULTS A total of 134 patients underwent cholecystectomy for US-detected gallbladder polyps. After histopathologic examination, pseudopolyps were found in 75 (56%) specimens with dysplastic or malignant polyps seen in only six (4.5%) specimens. Mean size for neoplastic polyps was 33 mm. The positive predictive value for US in detecting neoplastic polyps in this study was 4.5%, which is significantly lower than the 10%-15% reported previously. CONCLUSIONS Although the prevalence of neoplastic polyps in this study is higher than in the previous literature, the distribution of pseudopolyps and true polyps is as expected. With all malignant polyps being >10 mm in diameter, these findings support the current size thresholds stated in European guidelines. The poor diagnostic accuracy of US demonstrated may have led to significant number of patients undergoing unnecessary surgical intervention, further supporting the argument for improved strategies for the investigation of gallbladder polyps.

Abstract
OBJECTIVE Unlike adults, gallbladder polyps (GPs) are rare in childhood. The aim of this study was to evaluate patients with a GP diagnosis. METHODS Patients who were diagnosed with GP via ultrasonography from October 2012 to October 2017 were retrospectively evaluated in terms of sociodemographic characteristics and laboratory findings. RESULTS The study included 19 patients diagnosed with GP and followed up in our department. The patients comprised 14 (73.6%) girls with a mean age of 13.9 ± 4.1 years and a mean follow-up period of 10.2 ± 5.4 months (range, 3-26 months). The most common presenting symptom of the patients (n = 15, 78.9%) for ultrasonography was abdominal pain without biliary symptoms. Location of the polyps was in the corpus in 55% of patients, and either in the fundus (20%) or the neck of the gallbladder (25%). The average diameter of the polyps was 4.5 ± 1.6 mm (range, 2-9 mm). Multiple polyps were observed in 3 patients. No significant change in the number or size of polyps was noted at the end of the follow-up periods. Cholecystectomy was applied to 1 patient who had >5 polyps with a rapid increase in size, and the pathology report was hamartomatous polyp. There was no remarkable change in the clinical or laboratory findings of other patients during the follow-up period. CONCLUSION In this study, GPs could be seen in young children as young as 16 months of age and ultrasonography is sufficient for follow-up in stable and asymptomatic patients.

Abstract
Background Preoperative differentiation of malignant and premalignant gallbladder polyps (GBPs) from benign lesions is a key imperative to guide treatment decision-making. We aimed to characterize the various types of GBPs and sought to identify the risk factors for neoplastic polyps. Our findings may help optimize treatment strategy. Methods Retrospective analysis of 686 patients with post-cholecystectomy pathologically-proven GBPs between January 2003 and December 2016. The patients were classified into non-neoplastic polyp group, benign neoplastic polyp group, and adenoma canceration group. Clinical features, ultrasound findings, and results of laboratory investigations and histopathological examination were reviewed and compared between the groups. Results Out of 686 patients, 542 (79.0%) had non-neoplastic polyps, 134 (19.5%) had neoplastic polyps, and 10 (1.5%) had adenoma canceration. The mean age was 46.06±12.12 years; 383 (55.8%) patients were female. The median (25th percentile, 75th percentile) time between diagnosis and surgery in the cholesterol polyp group [24 (3.5, 60) months] was significantly longer than that in adenoma [12 (2, 60) months] and adenoma canceration [5 (0.475, 12) months] groups. The mean diameter was 1.14±0.61 cm (range, 0.5-8.4 cm). Three hundred twelve (45.5%) patients had solitary polyps and intralesional blood flow was observed in 41 (6.0%) patients. On univariate analysis, age >49.5 years, polyp size >1.15 cm, solitary polyp, intralesional blood flow, absence of symptoms, and lack of cholecystitis showed a significant association with adenoma. On multivariate analysis, polyp size (>1.15 cm), intralesional blood flow, and lack of cholecystitis were independent predictors of adenoma. Conclusions Polyp size >1.15 cm, intralesional blood flow, and lack of cholecystitis were predictors of neoplastic polyps. Malignant transformation of adenoma may occur over a relatively short time.

Abstract
AIM To investigate whether gallbladder polypoid lesions (GPL) are accurately reported and managed by radiologists, sonographers, general practitioners (GPs) and surgeons. MATERIALS AND METHODS Consecutive abdominal ultrasound examinations indicating GPL in symptomatic patients performed during 2011-2013 were captured and analysed. The study comprised 244 patients who satisfied the inclusion criteria. RESULTS Of the ultrasound reports retrieved, 238/244 reports (98%) erroneously described the polypoid lesions as polyps. One hundred and thirty-two of the 244 (54%) reports recommended follow-up, 5/244 (2%) recommended no follow-up, 35/244 (14%) deemed the findings insignificant, and 72/244 (30%) did not comment. Regarding GP referral, 57/184 (31%) patients were correctly referred to general surgeons, 20/184 (11%) to gastroenterologists, and 107/184 (58%) were not referred to secondary care. Forty-three of the 244 patients (18%) underwent cholecystectomy. Regarding subsequent biliary presentations, 63/244 patients (26%) presented at a later date with biliary symptoms; 13/63 (21%) of these eventually had cholecystectomies with 2/13 (15%) experiencing potentially life-threatening pancreatitis episodes. Regarding the surgical approach, differences were observed in the way individual surgeons managed polypoid lesions, with some veering towards cholecystectomy, others towards follow-up ultrasound, and some towards discharge. CONCLUSION GPL tend to be misreported by radiologists and sonographers, unappreciated by GPs, and variably managed by surgeons. These factors delay definitive therapy and seem to contribute to future biliary presentations. A fresh educational approach is required to raise awareness among radiologists, sonographers, and GPs regarding the clinical relevance and possible representations of GPL, and a uniform strategy is needed for managing GPL.

Abstract
Background The aim of our study was to investigate the prevalence and natural long-term progression of gallbladder polyps in a random sample of the general population. Methods Four hundred and thirteen subjects (190 women, 223 men; aged 29–75 years) were studied first in 2002 and again eleven years later in 2013. All subjects were interviewed using a standardised questionnaire, anthropometric data were recorded, and an abdominal ultrasound scan was carried out. Results The prevalence of gallbladder polyps was 6.1% (115/1880) in the 2002 study and 12.1% (50/413) in the 2013 follow-up study. After eleven years, 36 subjects (8.7%, 36/413) had developed new polyps, thirteen subjects (48.1%, 13/27) no longer had gallbladder polyps, and 14 subjects (51.9%, 14/27) still had polyps. The number of polyps had increased in six of these subjects (43%, 6/14), decreased in a further six (43%, 6/14), and remained unchanged in two (14%, 2/14). The mean polyp size was 4.7 mm (± 2.2 mm, range 2–20 mm) in 2002 and 4.0 mm (± 1.9 mm, range 0.5–11 mm) at follow-up. A decrease in polyp size was noted in seven (50%) of the 14 subjects, an increase in size in five subjects (35.7%), and no change in two subjects (14.3%). The shape of the polyps had changed from pedunculated to sessile in two subjects (14.3%, 2/14) and from sessile to pedunculated in one subject (7.1%, 1/14). Conclusions In long-term follow-up, the prevalence of gallbladder polyps increased, with new lesions developing in 8.7% of the population. Polyps persisted in 51.9% of the subjects who had them in the original study and disappeared in the other 48.1%.

Abstract
INTRODUCTION Gallbladder polyps (GBPs) are generally harmless, but the planning of diagnosis and treatment of the GBP is of clinical importance due to the high mortality risk of delays in the diagnosis of gallbladder carcinomas that show polypoid development. MATERIALS AND METHODS GBPs are usually incidentally detected during ultrasonographic (USG) examinations of the abdomen. The risk of carcinoma development from polypoid lesions in the literature is reported as 0-27%. There is no consensus about the management of the GBPs. Herein, we reviewed the contemporary data to update our knowledge about diagnosis and treatment of gallbladder polyps. RESULTS Polyps can be identified in five different groups, primarily as neoplastic and non-neoplastic. Cholesterol polyps account for 60% of all cases. The most common (25%) benign polypoid lesions after cholesterol polyps are adenomyomas. CONCLUSION Ultrasonography and endoscopic ultrasonography seems to be the most important tool in differential diagnosis and treatment. Ultrasonography should be repeated in every 3-12 months in cases that are thought to be risky. Nowadays, the most common treatment approach is to perform cholecystectomy in patients with polyps larger than 10 mm in diameter. Radical cholecystectomy and/or segmental liver resections should be planned in cases of malignancy. HOW TO CITE THIS ARTICLE Dilek ON, Karsu S, et al.

Hepatol Commun 2018; 2:1440-1445. [PMID: 30556033 PMCID: PMC6287476 DOI: 10.1002/hep4.1276] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Accepted: 10/12/2018] [Indexed: 01/13/2023] Open
Abstract
The prevalence polyps (GBPs) in the general population has been estimated to be approximately 5%, with up to 10% of these being dysplastic or malignant. Previous studies have suggested that patients with primary sclerosing cholangitis (PSC) have increased frequency of GBPs. However, data on the prevalence, risk factors, and outcome of GBPs in these patients are sparse. This case‐control study investigates the frequency, risk factors, and outcome of GBPs in patients with PSC. In this study, 363 patients with an established diagnosis of PSC based on magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), or liver biopsy were identified. Patients with at least one abdominal imaging and no history of cholecystectomy before the first available abdominal imaging were included. The presence of GBPs was confirmed by abdominal computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound. Patients with GBPs were compared to those without GBPs. Furthermore, patients with malignant/premalignant polyps were compared to those with benign polyps. The frequency of GBPs in patients with PSC was 10.6%. There was no significant difference in the frequency of inflammatory bowel disease (IBD) between the two groups. Of the 16 with GBPs who underwent cholecystectomy, 10 had malignant/premalignant lesions, of whom 6 had adenocarcinoma, and 4 had high‐grade dysplasia. Of the 6 patients with adenocarcinoma, 4 had lesions >10 mm, 1 had a lesion as small as 4 mm, and 1 had a 7‐mm lesion. Conclusion: GBPs may be frequently seen in patients with PSC. These lesions seem to occur independent of IBD. In patients with PSC, even small GBPs appear to have a risk of malignancy. These findings suggest that patients with PSC and GBPs may benefit from cholecystectomy, regardless of the size of the polyp.

Abstract
The finding of gallbladder polyps on imaging studies prompts further workup. Imaging results are often discordant with final pathology. The goal of this study is to compare polypoid lesions of the gallbladder found on preoperative ultrasound (US) with final pathologic diagnosis after cholecystectomy to help guide clinical decision-making. A retrospective study was conducted identifying adult patients who were diagnosed with polyps via US and who underwent cholecystectomy from 2008 through 2015. Imaging data, final pathology, and demographics were manually reviewed. A total of 2290 cholecystectomy patients had US-based polyps. Of these, 1661 patients (73%) did not have polyps on final pathology; primarily, stones or sludge were identified. Adenomyosis was diagnosed in 61 patients (2.7%). A total of 556 patients (24.2%) had pathologic polypoid lesions with the following breakdown: 463 (20.2%) cholesterol polyps, 43 other benign polyps (1.8%), 40 adenomas (1.7%), and 10 adenocarcinomas (0.4%). All patients with adenocarcinoma were older than 40 years and 91 per cent had US findings of polyps >10 mm. Ultrasound alone is an unreliable method of detecting real gallbladder polyps. This large database study found a very low risk of cancer. Size on US and patient age should be considered in the selection of appropriate surgical candidates with sonographic “polyps.”

Abstract
BACKGROUND AND OBJECTIVE Although the incidence of carcinoma is not high in gallbladder polyps, it is essential to diagnose gallbladder cancer at an early stage to achieve a good therapeutic outcome. Therefore, the aim of this study was to define the characteristics of gallbladder polyps to establish sound criteria for surgical indications. METHODS In the current study, data from 516 patients with gallbladder polyps who underwent cholecystectomy were reviewed to correlate clinical features with histopathologic findings and identify risk factors with receiver-operating characteristic curves (ROCs). RESULTS Among the 516 patients who underwent cholecystectomy, 24 patients (4.6%) had cancerous change. The cancer group was significantly older (65.5 years (median, range 35-85)) than the non-cancer group (42 years (median, range 23-82)) (p < 0.001). Among the cancer group, the preoperative polyp size on ultrasonography was significantly larger (14 mm (median, range 9-30)) than the polyps in the non-cancer group (10.4 mm (median, range 1.9-45)) (p < 0.001). Using the ROC curve and considering the sensitivity and specificity for predicting malignant polyps, 12 mm may be a reasonable cutoff for considering a malignant polyp. CONCLUSIONS Gallbladder polyps with 10-11 mm in asymptomatic young patients (less than 50 years old) have low risk of malignancy, and therefore, a careful "wait and see with follow up by using ultrasonography strategy" might be more appropriate than immediate cholecystectomy.

Abstract
GOAL To provide the statistical predictive model for neoplastic potential of gallbladder polyp (GBP). BACKGROUND Many studies have attempted to define the risk factors for neoplastic potential of GBP. It remains difficult to precisely adapt the reported risk factors for the decision of surgery. Estimating the probability for neoplastic potential of GBP using a combination of several risk factors before surgical resection would be useful in patient consultation. STUDY We collected data of patients confirmed as GBP through cholecystectomy at Samsung Medical Center between January 1997 and March 2015. Those with a definite evidence for malignancy, such as adjacent organ invasion, metastasis on preoperative imaging studies, polyp >15 mm, and absence of proper preoperative ultrasonographic imaging were excluded. A total of 1976 patients were enrolled. To make and validate the predictive model, we divided the cohort into the modeling group (n=979) and validation group (n=997). Clinical information, ultrasonographic findings, and blood tests were retrospectively analyzed. RESULTS Clinical factors of older age, single lesion, sessile shape, and polyp size showed statistical significance for neoplastic potential of GBP in the modeling group. A predictive model for neoplastic potential of GBP was constructed utilizing the statistical outcome of the modeling group. Statistical validation was performed with the validation group to determine the optimal clinical sensitivity and specificity of the predictive model. Optimal cut-off value for neoplastic probability was 7.4%. CONCLUSIONS The predictive model for neoplastic potential of GBP may support clinical decisions before cholecystectomy.

[PMID: 28695432 DOI: 10.1007/s11605-017-3476-0] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2017] [Accepted: 06/12/2017] [Indexed: 01/31/2023]
Abstract
BACKGROUND AND AIM Gallbladder polypoid-lesions (GPs) are commonly seen on ultrasonography (USG), but several aspects of this problem are ill-defined. This study aimed to analyze clinic and pathologic characteristics of 1446 USG-detected GPs, identify predictive factors for cholesterol lesions and malignancy, and provide comments and recommendations on specific aspects of GPs. METHODS We retrospectively analyzed clinic files of 1446 patients who underwent cholecystectomy for USG-detected GPs between 2008 and 2015 in Gallbladder Diseases Center, East Hospital of Tongji University. RESULTS For the 1446 patients, the F: M ratio and the mean age were 1.06: 1 and 45 years, and most of them were asymptotic (80.3%) and had multiple polyps (62.5%). All the 1446 GPs were classified into three categories: cholesterol, benign non-cholesterol, and malignant lesions, with respective proportion of 87.1% (1260), 11.2% (162), and 1.7% (24). Over half of benign non-cholesterol lesions, of which most were premalignant neoplasm (adenoma), were less than 10 mm. Multiple number and the presence of lipid abnormalities were significantly more associated with cholesterol than non-cholesterol lesions, with odd ratios (OR) of 2.9 (P < 0.001) and 1.6 (P = 0.023), respectively. Age ≥50 years, present symptoms, size ≥10 mm and concurrent gallstones were independent predictive factors to discriminate malignant polyps from premalignant lesions, with ORs of 16.5 (P < 0.001), 6.3 (P = 0.013), 41.5 (P = 0.014), and 18.0 (P = 0.002), respectively. CONCLUSIONS According to our proposed classification, the vast majority of GPs were cholesterol lesions without malignant potential and associating with metabolic diseases. We strongly recommend that risk factors of GPs be investigated by subtypes, and patients with GPs be treated with personalized and differentiated strategies.

Abstract
Gallbladder polypoid-lesions (GPs) are found in 5-10% of the general population. Although the majority of GPs are asymptomatic and benign in nature, some of them can develop into cancer, which carries a poor prognosis. Currently, the risk factors, natural history and classification of GPs remain unclear, differentiation of benign from malignant or premalignant GPs based on available diagnostic modalities and/or features of patients and GPs remain difficult, and there are still no evidence-based guidelines to dictate when and how GPs of varying sizes and subtypes should be managed. All of these facts have left GPs in uncertainty. Areas covered: A literature search was performed using the terms 'gallbladder polyps' AND 'polypoid lesion of gallbladder' in the PubMed database from January 2000 to September 2016. Original and review articles on almost all aspects of GPs in humans, especially diagnosis, treatment and surveillance, were reviewed and analyzed. Reference lists of reviews and original articles were also examined for relevant publications. Expert commentary: The present article summarizes almost all aspects of GPs, analyzes the controversies, and outlines our data and comments. It is the authors' purpose that this article be beneficial for scientific, accurate and appropriate management of GPs.

Abstract
OBJECTIVES To assess important features for risk stratification of gallbladder (GB) polyps >10 mm using high-resolution ultrasonography (HRUS) and texture analysis. METHODS We included 136 patients with GB polyps (>10 mm) who underwent both HRUS and cholecystectomy (non-neoplastic, n = 58; adenomatous, n = 32; and carcinoma, n = 46). Two radiologists retrospectively assessed HRUS findings and texture analysis. Multivariate analysis was performed to identify significant predictors for neoplastic polyps and carcinomas. RESULTS Single polyp (OR, 3.680-3.856) and larger size (OR, 1.450-1.477) were independently associated with neoplastic polyps (p < 0.05). In a single or polyp >14 mm, sensitivity for differentiating neoplastic from non-neoplastic polyps was 92.3%. To differentiate carcinoma from adenoma, sessile shape (OR, 9.485-41.257), larger size (OR, 1.267-1.303), higher skewness (OR, 6.382) and lower grey-level co-occurrence matrices (GLCM) contrast (OR, 0.963) were significant predictors (p < 0.05). In a polyp >22 mm or sessile, sensitivity for differentiating carcinomas from adenomas was 93.5-95.7%. If a polyp demonstrated at least one HRUS finding and at least one texture feature, the specificity for diagnosing carcinoma was increased to 90.6-93.8%. CONCLUSION In a GB polyp >10 mm, single and diameter >14 mm were useful for predicting neoplastic polyps. In neoplastic polyps, sessile shape, diameter >22 mm, higher skewness and lower GLCM contrast were useful for predicting carcinoma. KEY POINTS • Risk of neoplastic polyp is low in <14 mm and multiple polyps • A sessile polyp or >22 mm has increased risk for GB carcinomas • Higher skewness and lower GLCM contrast are predictors of GB carcinoma • HRUS is useful for risk stratification of GB polyps >1 cm.

Abstract
Objectives The management of incidentally detected gallbladder polyps on radiological examinations is contentious. The incidental radiological finding of a gallbladder polyp can therefore be problematic for the radiologist and the clinician who referred the patient for the radiological examination. To address this a joint guideline was created by the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), European Association for Endoscopic Surgery and other Interventional Techniques (EAES), International Society of Digestive Surgery – European Federation (EFISDS) and European Society of Gastrointestinal Endoscopy (ESGE). Methods A targeted literature search was performed and consensus guidelines were created using a series of Delphi questionnaires and a seven-point Likert scale. Results A total of three Delphi rounds were performed. Consensus regarding which patients should have cholecystectomy, which patients should have ultrasound follow-up and the nature and duration of that follow-up was established. The full recommendations as well as a summary algorithm are provided. Conclusions These expert consensus recommendations can be used as guidance when a gallbladder polyp is encountered in clinical practice. Key Points • Management of gallbladder polyps is contentious • Cholecystectomy is recommended for gallbladder polyps >10 mm • Management of polyps <10 mm depends on patient and polyp characteristics • Further research is required to determine optimal management of gallbladder polyps

Polypoid lesions of the gallbladder: analysis of 1204 patients with long-term follow-up. Surg Endosc 2016; 31:2776-2782. [PMID: 28039652 DOI: 10.1007/s00464-016-5286-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Accepted: 10/05/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND Polypoid lesions of the gallbladder (PLG) are common, and most are benign. Few lesions are found to be malignant, but are not preoperatively distinguished as such using common imaging modalities. Therefore, we compared characteristics of benign and malignant PLGs in depth. METHODS We enrolled 1204 consecutive patients diagnosed with PLG at Taipei Veterans General Hospital between January 2004 and December 2013. Patients underwent either surgery or regular follow-up with various imaging modalities for at least 24 months. The mean follow-up duration was 72 ± 32 months. RESULTS Of 1204 patients, 194 underwent surgical treatment and 1010, regular follow-up. In addition, 73 % patients were asymptomatic. The mean PLG size was 6.9 ± 7.7 (range 0.8-129) mm; the PLGs of 337 patients (28 %) grew during their follow-up periods. The majority of PLGs (90.4 %) were single lesions, and 10.5 % of patients had associated gallstones. The PLGs of 20.1 % of surgical patients were malignant. Malignant PLGs were found in 32.4 % of patients ≥50 years old and in 4.7 % of those <50 years old (p < 0.001). Right quadrant abdominal pain, epigastric pain, and body weight loss were the three most common symptoms associated with malignancy. Malignant PLGs were significantly larger than benign lesions (means: 27.5 ± 18.4 mm vs. 12.3 ± 12.3 mm, respectively, p < 0.001). Notably, the size of 5 % of malignant PLGs was 3-5 mm, and that of 8 % was 5-10 mm. The negative predictive value for gallbladder malignancy was 92.8 % based on a size ≥10 mm and 100 % based on a size ≥3 mm. CONCLUSIONS Our study reassesses the PLG size that warrants more aggressive intervention. Cholecystectomy remains mandatory for PLGs > 10 mm, but should also be considered a definitive diagnostic and treatment modality for PLGs with diameters of 3-10 mm.

Preoperative predictive factors for gallbladder cholesterol polyp diagnosed after laparoscopic cholecystectomy for polypoid lesions of gallbladder. Ann Hepatobiliary Pancreat Surg 2016; 20:180-186. [PMID: 28261697 PMCID: PMC5325147 DOI: 10.14701/ahbps.2016.20.4.180] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2016] [Revised: 10/18/2016] [Accepted: 10/20/2016] [Indexed: 12/28/2022] Open
Abstract
BACKGROUNDS/AIMS We investigated patients' clinical and radiological data to determine preoperative factors that predict cholesterol gallbladder (GB) polyps of large size, which can be helpful for decision on further diagnostic tools. METHODS In this study, we retrospectively analyzed 126 patients who underwent laparoscopic cholecystectomy for GB polyps >10 mm diagnosed preoperatively by abdominal ultrasonography between February 2002 and February 2016 in Department of Surgery, Sanggye Paik Hospital. Patients were divided into non-cholesterol polyps group and cholesterol polyps group, based on the postoperative pathologic diagnosis. Clinical and radiological data, such as gender, age, body weight, height, body mass index (BMI), laboratory findings, size, number and shape of the polypoid lesions, and presence of the concurrent GB stone were compared between the two groups. RESULTS Of the 126 cases, 73 had cholesterol polyps (57.9%) and 53 cases were non-cholesterol polyps (42.1%). The younger age (<48.5 years), size of polyp <13.25 mm and multiple polyps were independent predictive variables for cholesterol polyps, with odd ratios (OR) of 2.352 (p=0.045), 5.429 (p<0.001) and 0.472 (p<0.001), respectively. CONCLUSIONS Age, size and polyp number were used to predict cholesterol GB polyp among polypoid lesions of the gallbladder >10 mm. For cases in which these factors are not applicable, it is strongly recommended to evaluate further diagnostic tools, such as computed tomography, endoscopic ultrasonography and tumor markers.

Abstract
Purpose To evaluate the prevalence of tumefactive sludge of the gallbladder detected at ultrasonography (US) and to assess whether any clinical and imaging differences exist between benign and malignant tumefactive sludge. Materials and Methods The institutional review board approved this retrospective study. The requirement for informed consent was waived. The study included a cohort (n = 6898) of patients with gallbladder sludge drawn from all adults (n = 115 178) who underwent abdominal US between March 2001 and March 2015. Tumefactive sludge was identified according to the following US findings: (a) nonmovable mass-like lesion and (b) absence of posterior acoustic shadowing at B-mode US and vascularity at color Doppler US. Follow-up examinations were arranged to ascertain whether the results showed true sludge or gallbladder cancer. Risk factors for malignant tumefactive sludge based on clinical and US characteristics were identified with multivariate logistic regression analysis. Results The prevalence of gallbladder and tumefactive sludge at abdominal US during the observation period was 6.0% (6898 of 115 178) and 0.1% (135 of 115 178), respectively. Twenty-eight (20.7%) patients were lost to follow-up. Of the 107 with tumefactive sludge, 15 (14%) were confirmed to have malignant tumefactive sludge. The risk factors for malignant tumefactive sludge were old age (odds ratio [OR], 1.06; P = .035), female sex (OR, 5.48; P = .014), and absence of hyperechoic spots within the sludge (OR, 6.78; P = .008). Conclusion Although the prevalence of tumefactive sludge at US was rare, a considerable proportion of patients had a malignancy. Careful follow-up is essential, especially for older patients, women, and those with an absence of hyperechoic spots at US. © RSNA, 2016 Online supplemental material is available for this article.

Abstract
Gallbladder polyps are seen on as many as 7% of gallbladder ultrasonographic images. The differential diagnosis for a polypoid gallbladder mass is wide and includes pseudotumors, as well as benign and malignant tumors. Tumefactive sludge may be mistaken for a gallbladder polyp. Pseudotumors include cholesterol polyps, adenomyomatosis, and inflammatory polyps, and they occur in that order of frequency. The most common benign and malignant tumors are adenomas and primary adenocarcinoma, respectively. Polyp size, shape, and other ancillary imaging findings, such as a wide base, wall thickening, and coexistent gallstones, are pertinent items to report when gallbladder polyps are discovered. These findings, as well as patient age and risk factors for gallbladder cancer, guide clinical decision making. Symptomatic polyps without other cause for symptoms, an age over 50 years, and the presence of gallstones are generally considered indications for cholecystectomy. Incidentally noted pedunculated polyps smaller than 5 mm generally do not require follow-up. Polyps that are 6-10 mm require follow-up, although neither the frequency nor the length of follow-up has been established. Polyps that are larger than 10 mm are typically excised, although lower size thresholds for cholecystectomy may be considered for patients with increased risk for gallbladder carcinoma, such as patients with primary sclerosing cholangitis.

Abstract
BACKGROUND There are no evidence-based guidelines to dictate when Gallbladder Polyps (GBPs) of varying sizes should be resected. AIM To identify factors that accurately predict malignant disease in GBP; to provide an evidence-based algorithm for management. METHODS A systematic review following PRISMA guidelines was performed using terms "gallbladder polyps" AND "polypoid lesion of gallbladder", from January 1993 and September 2013. Inclusion criteria required histopathological report or follow-up of 2 years. RTI-IB tool was used for quality analysis. Correlation with GBP size and malignant potential was analysed using Euclidean distance; a logistics mixed effects model was used for assessing independent risk factors for malignancy. RESULTS Fifty-three articles were included in review. Data from 21 studies was pooled for analysis. Optimum size cut-off for resection of GBPs was 10 mm. Probability of malignancy is approximately zero at size <4.15 mm. Patient age >50 years, sessile and single polyps were independent risk factors for malignancy. For polyps sized 4 mm-10 mm, a risk assessment model was formulated. CONCLUSIONS This review and analysis has provided an evidence-based algorithm for the management of GBPs. Longitudinal studies are needed to better understand the behaviour of polyps <10 mm, that are not at a high risk of malignancy, but may change over time.

Abstract
Gallbladder carcinoma (GBC) is the most common biliary epithelial malignancy, with an estimated 10,910 new cases and 3700 deaths per year (Siegel et al. in CA Cancer J Clin 65:5–29, 2015 [1]). This disease’s insidious nature and typically late presentation place it among the most lethal of invasive neoplasms. Gallbladder cancer spreads early by lymphatic or hematogenous metastasis and by direct invasion into the liver. While surgery may well be curative at early stages, both surgical and nonsurgical treatments remain largely unsuccessful in patients with more advanced disease.
