Abstract
Human gallstones are the most common disorder in the biliary system, affecting up to 20 % of the adult population. The formation of gallstones is primarily due to the supersaturating of cholesterol in bile. In order to comprehend gallstone disease in detail, it is necessary to have accurate information about phase identification and molecular structure. Different types of gallstone samples were collected from the Middle East area after surgical operations including; cholesterol, pigment, and mixed gallstones. To estimate the basic information about the stone formation and the pathophysiology of cholelithiasis as well as to classify the collected human gallstones, attenuated total reflection Fourier transform Infrared spectrometry (ATR-FTIR) was used to analyze the different gallstone structures in the wavenumber range from 400 to 4000 cm-1. Calcium bilirubinate was specified by the bands at 1662 cm-1, 1626 cm-1, and 1572 cm-1, while cholesterol rings were designated by the bands at 1464, 1438, 1055, and 1022 cm-1. It can be assumed that all samples consist of mixed gallstones based on the doublets at 1375 cm-1 and 1365 cm-1. The levels of calcium bilirubin and various minerals varied among the analyzed samples, indicating the heterogeneity in their composition and suggesting potential implications for gallstone formation. Based on the quantitative phase analysis using synchrotron radiation X-ray diffraction (SR-XRD), two phases of anhydrous cholesterol as a major content and one phase of monohydrate cholesterols as trace content represent the main components of most of the gallstones. Additional phases of calcium carbonate in the form of calcite, vaterite, aragonite, and bilirubinate were also quantified. According to the outcomes of the FTIR and the SR-XRD measurements, there exists a statistical correlation between the different types of chemical constituents of the gallstones.

Abstract
The Japanese Society of Gastroenterology first published evidence-based clinical practice guidelines for cholelithiasis in 2010, followed by a revision in 2016. Currently, the revised third edition was published to reflect recent evidence on the diagnosis, treatment, and prognosis of cholelithiasis conforming to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Following this revision, the present English version of the guidelines was updated and published herein. The clinical questions (CQ) in the previous version were reviewed and rearranged into three newly divided categories: background questions (BQ) dealing with basic background knowledge, CQ, and future research questions (FRQ), which refer to issues that require further accumulation of evidence. Finally, 52 questions (29 BQs, 19 CQs, and 4 FRQs) were adopted to cover the epidemiology, pathogenesis, diagnosis, treatment, complications, and prognosis. Based on a literature search using MEDLINE, Cochrane Library, and Igaku Chuo Zasshi databases for the period between 1983 and August 2019, along with a manual search of new information reported over the past 5 years, the level of evidence was evaluated for each CQ. The strengths of recommendations were determined using the Delphi method by the committee members considering the body of evidence, including benefits and harms, patient preference, and cost-benefit balance. A comprehensive flowchart was prepared for the diagnosis and treatment of gallbladder stones, common bile duct stones, and intrahepatic stones, respectively. The current revised guidelines are expected to be of great assistance to gastroenterologists and general physicians in making decisions on contemporary clinical management for cholelithiasis patients.

Ann Hepatobiliary Pancreat Surg 2023; 27:277-286. [PMID: 37547937 PMCID: PMC10472125 DOI: 10.14701/ahbps.23-010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 04/02/2023] [Accepted: 04/05/2023] [Indexed: 08/08/2023] Open
Abstract
Backgrounds/Aims To study histopathological changes in gall bladder mucosa in cholelithiasis patients, and analyse their relation to the number and size of gallstones. These findings were evaluated in the context of age distribution of the study population. Methods One hundred cases of cholecystectomy were part of the study, which was conducted in collaboration with the pathology department. The time period of the study was January 2020 to June 2021. Results Maximum cases had multiple stones (69.0%), while one third cases (31.0%) had solitary stones. While initial univariate analysis showed age (odds ratio [OR], 6.882; p = 0.043), gallstone number (OR, 9.1; p = 0.050), gallstone size (OR, 17.111; p = 0.013), and duration of symptom (OR, 34.125; p = 0.001) to be significant risk factors associated with gallbladder carcinoma, multivariate analysis found none of these variables to be significant. However, conditional multivariate analysis for the duration of symptom (p = 0.008; OR, 21.118) yielded significant p- value. With histopathological diagnoses, 5% of cases had gallbladder cancer. Conclusions This study shed light on the rising incidence of cholelithiasis in the young population and the high rate of gallbladder carcinoma in Punjab, India. Although gall stone characteristics (size, number) and patient age appeared to be significant risk factors when their individual relation with gallbladder carcinoma was studied, multivariate analysis, could not prove that. Conditional multivariate analysis showed the duration of symptom to be the only significant risk factor associated with gallbladder carcinoma. Further research with larger sample size is needed to study the rising incidence of gallbladder carcinoma, and the risk factors associated with it.

Abstract
A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In a patient with symptomatic gallstone disease does the presence of a large sized gallstone associated with a higher risk of gallbladder cancer? Using the reported search, 3876 papers were found. 6 studies were deemed to be suitable to answer the question. The outcome assessed was the relationship between the presence of large sized gallstones and the risk of gallbladder cancer. It appears from the current available evidence that there is a strong association of a large sized gallstones and gallbladder cancer. Larger stones (>3 cm) have the greatest risk to develop gallbladder cancer, especially in symptomatic gallstone disease patients. Authors recommend special care for this patient's group and to warrant cholecystectomy when the clinical condition allows. A strong relationship between the gallstone size and gallbladder cancer. Stones larger than 3 cm have the highest risk. Cholecystectomy is warranted when the clinical condition allows.

Abstract
INTRODUCTION Giant/large gallstones have high risk of complications, and technical difficulties during surgery. This case series is the largest ever reported. PRESENTATION OF CASES Case 1: Female (44 years), with one year intermittent right upper quadrant colicky pain. Ultrasound: large gallstone (normal gallbladder). Elective laparoscopic cholecystectomy (LC): 6 × 4 × 3.3 cm gallstone. Case 2: Female (41 years), presented to emergency room with 3 days right upper quadrant pain/tenderness, vomiting, and positive murphy's sign. Ultrasound: large gallstone, calculus cholecystitis. Emergency LC: 4.5 × 3.1 × 3.5 cm gallstone. Case 3: Male (38 years), with history of gallstones and acute cholecystitis presented with intermittent right upper quadrant pain (2 months) and vomiting. Normal abdominal examination. Ultrasound: large gallstone. Elective LC: 4.1 × 4 × 3.6 cm gallstone. CONCLUSIONS Gallstones >5 cm are very rare, with higher risk of complications. Gallbladder should be removed even if asymptomatic. Gallstones >3 cm have increased risk for gallbladder cancer, biliary enteric fistula and ileus. LC has challenges that include grasping the gallbladder wall, exposure of Calot's triangle, and retrieval of gallbladder out of the abdomen. LC appears to be procedure of choice and should be performed by an experienced surgeon, considering the possibility of conversion to open cholecystectomy in case of inability to expose the anatomy or intraoperative difficulties.

Abstract
Gallbladder stone is a major risk factor for gallbladder carcinoma (GBC), while there is still a controversy whether period of follow-up since newly diagnoses of asymptomatic gallstones increases the risk of GBC. In this study, 10 GBC patients and 30 patients with gallstones were admitted to our hospital. Patients with gallstones were divided into 3 groups according to the follow-up time, involving 10 patients with follow-up period of 1–3 years (GS3 group), 10 patients with follow-up period of 5–10 years (GS5 group), and 10 patients with follow-up period of more than 10 years (GS10 group). Tumor and para-tumor tissues of GBC patients, and gallbladder tissues of gallstone patients were collected. RNA sequencing was performed on the 50 samples. Besides, 1,704 differentially expressed genes (DEGs) were identified in tumors compared with para-tumor tissues of 10 GBC patients, which were enriched into some well-known cancer-related pathways, such as PI3K-Akt, mitogen-activated protein kinase (MAPK), Ras, and Wnt signaling pathways, and the most significant pathway was neuroactive ligand-receptor interaction. Patients with gallstones with periods of follow-up equal to 1–3 and > 10 years showed to have higher cancer risk than those with 5–10 years. ALPP and GPR87 are potential biomarkers for predicting cancer risk in patients with gallstones. The in vitro results revealed that GPR-87 can promote the proliferation, migration, and invasion of GBC cells. Herein, we explored the relationship between GBC patients and patients with gallstones with different periods of follow-up in transcriptome level.

Abstract
INTRODUCTION Carcinoma gallbladder is a very lethal disease. It can get detected incidentally after laparoscopic cholecystectomy. The overall outcome of incidentally detected carcinoma gallbladder is a matter of debate in literature. AIM To estimate the overall incidence of the incidental gallbladder carcinoma, the various risk factors associated with it and factors affecting overall survival in patients who underwent laparoscopic cholecystectomy with eventual histology turning out to be carcinoma gallbladder. METHODS Data of all the patients undergoing laparoscopic cholecystectomies in one surgical unit under the Department of Surgery at All India Institute of Medical Sciences, New Delhi, India, between January 2014 and December 2018 was retrospectively analyzed. All patients with incidental carcinoma gallbladder were followed up and completion radical cholecystectomy was performed. The demographic profile, preoperative imaging, intra-operative finding, histopathology of primary surgery, and median interval between two surgeries were analyzed to look for various risk factors associated with incidental carcinoma gallbladder and factors affecting overall survival. RESULTS Incidence of the incidental carcinoma gallbladder was 0.51% with a female/male ratio of 4:1 and mean age of 47.2 years. Preoperative imaging of most of them was suggestive of chronic cholecystitis; however, one patient had multiple gallbladder polyps. Six patients had uneventful laparoscopic cholecystectomy, while four had bile spillages intraoperatively. All the patients had adenocarcinoma on histopathology. Pathological staging of four patients was pT1b and six patients had pT2 tumor. The median interval between cholecystectomy and completion radical cholecystectomy in this series was 8 weeks. At the end of 19-month median follow-up, overall survival was 55.5%. CONCLUSION Incidence of incidental carcinoma gallbladder is 0.51%, most commonly affecting middle-aged females. Risk factors associated with incidental carcinoma gallbladder were found to be multiple gallbladder calculi, single large stone, and gallbladder polyps. Survival is better in males, young patients with uneventful primary surgery and better-differentiated pathology.

Abstract
"Gallbladder disease is one of the most common gastrointestinal diseases encountered in clinical practice. Surgical removal and percutaneous drainage are both widely available and effective in the management of acute cholecystitis. Several endoscopic approaches exist as an alternative to these interventions. These include transpapillary approaches via endoscopic retrograde cholangiopancreatography (ERCP), transmural drainage and access approaches via endoscopic ultrasound (EUS), and endoscopic surgical approaches using natural orifice transluminal endoscopic surgery (NOTES) techniques. This article reviews the epidemiology and pathophysiology of gallbladder diseases and discusses the various percutaneous, surgical, and endoscopic approaches to managing gallbladder disease."

Abstract
PURPOSE To determine whether virtual monochromatic imaging (VMI) increases detectability of noncalcified gallstones on dual-energy CT (DECT) compared with conventional CT imaging. MATERIALS AND METHODS This retrospective IRB-approved, HIPAA-compliant study included consecutive patients who underwent DECT of the abdomen in the Emergency Department during a 30-month period (July 1, 2013-December 31, 2015), with a comparison US or MR within 1-year. 51 patients (36F, 15M; mean age 52 years) fulfilled the inclusion criteria. All DECT were acquired on a dual-source 128 × 2 slice scanner using either 80/Sn140 or 100/Sn140 kVp pairs. Source images at high and low kVp were used for DE post-processing with VMI. Within 3 mm reconstructed images, regions of interest of 0.5 cm2 were placed on noncalcified gallstones and bile to record hounsfield units (HU) at VMI energy levels ranging between 40 and 190 keV. RESULTS Noncalcified gallstones uniformly demonstrated lowest HU at 40 keV and increase at higher keV; the HU of bile varied at higher keV. Few of the noncalcified stones are visible at 70 keV (simulating a conventional 120 kVp scan), with measured contrast (bile-stone HU difference) <10 HU in 78%, 10-20 HU in 20%, and >20 HU in 2%. Contrast was maximal at 40 keV, where 100% demonstrated >20 HU difference from surrounding bile, 75% >44 HU difference, and 50% >60 HU difference. A paired t test demonstrated a significant difference (p < 0.0001) between this stone-bile contrast at 40 vs. 70 keV and 70 vs. 190 keV. CONCLUSION Low keV virtual monochromatic imaging increased conspicuity of noncalcified gallstones, improving their detectability.

Abstract
Chronic inflammation has been known to be a risk for many kinds of cancers, including pancreatic and biliary tract cancer. Recently, inflammatory process has emerged as a key mediator of cancer development and progression. Many efforts with experimental results have been given to identify the underlying mechanisms that contribute to inflammation-induced tumorigenesis. Diverse inflammatory pathways have been investigated and inhibitors for inflammation-related signaling pathways have been developed for cancer treatment. This review will summarize recent outcomes about this distinctive process in pancreatic and biliary tract cancer. Taking this evidence into consideration, modulation of inflammatory process will provide useful options for pancreatic and biliary tract cancer treatment.

Abstract
Gallstone ileus is a rare cause of small bowel obstruction, classically occurring in patients with recurrent cholecystitis. The incidence of biliary enteric fistula and gallstone ileus in patients with large, asymptomatic gallstones is not known. We report a case of gallstone ileus, which occurred in the setting of a large, asymptomatic gallstone. This case suggests that large gallstones may warrant cholecystectomy, even in asymptomatic patients.

Abstract
BACKGROUND & AIMS No one knows exactly what proportion of gallstones cause clinical events among subjects unaware of their gallstone status. We investigated the long-term occurrence of clinical events of gallstones and associations between ultrasound observations and clinical events. METHODS We analyzed data from 3 randomly selected groups in the general population of urban Copenhagen (age, 30-70 y) participating in an international study of cardiovascular risk factors (the Multinational mONItoring of trends and determinants in CArdiovascular disease study). In this study, participants (n = 6037) were examined from 1982 through 1994, and underwent abdominal ultrasound examinations to detect gallstones. Our study population comprised 664 subjects with gallstones; subjects were not informed of their gallstone status. Participants were followed up for clinical events through central registers until December 31, 2011. Independent variables included ultrasound characteristics, age, sex, comorbidity, and female-associated factors, which were analyzed using Cox regression. RESULTS Study participants were followed up for a median of 17.4 years (range, 0.1-29.1 y); 99.7% of participants completed the study. A total of 19.6% participants developed events (8.0% complicated and 11.6% uncomplicated). Ten percent had awareness of their gallstones; awareness was associated with uncomplicated and complicated events. Stones larger than 10 mm were associated with all events (hazard ratio [HR], 2.31; 95% confidence interval [CI], 1.45-3.69), acute cholecystitis (HR, 9.49; 95% CI, 2.05-43.92), and uncomplicated events (HR, 2.55; 95% CI, 1.38-4.71), including cholecystectomy (HR, 2.69; 95% CI, 1.29-5.60). Multiple stones were associated with all events (HR, 1.68; 95% CI, 1.00-2.81), complicated events (HR, 2.52; 95% CI, 1.05-6.04), and common bile duct stones (HR, 11.83; 95% CI, 1.54-91). There was an association between gallstones more than 5 years old and acute cholecystitis. Female sex was associated with all and uncomplicated events. We found a negative association between participant age and all events, uncomplicated events, and acute cholecystitis. Comorbidities and female-associated factors (intake of birth control pills or estrogens and number of births) were not associated with events. Compared with men with a single stone of 10 mm or smaller (reference), women with multiple stones greater than 10 mm had the highest risk for events (HR, 11.05; 95% CI, 3.76-32.44; unadjusted absolute risk, 0.0235 events/person-years). CONCLUSIONS Fewer than 20% of subjects with gallstones develop clinical events. Larger, multiple, and older gallstones are associated with events. Further studies are needed to confirm the prediction rules.

Abstract
BACKGROUND Gallbladder disease is highly related to inflammation, but the inflammatory processes are not well understood. Bile provides a direct substrate in assessing the local inflammatory response that develops in the gallbladder. To assess the reproducibility of measuring inflammatory markers in bile, we designed a methods study of 69 multiplexed immune-related markers measured in bile obtained from gallstone patients. METHODS To evaluate assay performance, a total of 18 bile samples were tested twice within the same plate for each analyte, and the 18 bile samples were tested on two different days for each analyte. We used the following performance parameters: detectability, coefficient of variation (CV), intraclass correlation coefficient (ICC), and percent agreement (concordance among replicate measures above and below detection limit). Furthermore, we examined the association of analyte levels with gallstone characteristics such as type, numbers, and size. RESULTS All but 3 analytes (Stem Cell Factor, SCF; Thrombopoietin, TPO; sIL-1RI) were detectable in bile. 52 of 69 (75.4%) analytes had detectable levels for at least 50% of the subjects tested. The within-plate CVs were ⩽25% for 53 of 66 (80.3%) detectable analytes, and across-plate CVs were ⩽25% for 32 of 66 (48.5%) detectable analytes. Moreover, 64 of 66 (97.0%) analytes had ICC values of at least 0.8. Lastly, the percent agreement was high between replicates for all of the analytes (median; within plate, 97.2%; across plate, 97.2%). In exploratory analyses, we assessed analyte levels by gallstone characteristics and found that levels for several analytes decreased with increasing size of the largest gallstone per patient. CONCLUSIONS Our data suggest that multiplex assays can be used to reliably measure cytokines and chemokines in bile. In addition, gallstone size was inversely related to the levels of select analytes, which may aid in identifying critical pathways and mechanisms associated with the pathogenesis of gallbladder diseases.

Abstract
Gallbladder cancer (GBC) shows a marked geographical variation in its incidence. Middle-aged and elderly women are more commonly affected. Risk factors for its development include the presence of gallstones, chronic infection and pancreaticobiliary maljunction. Controversy remains in regard to the theory of carcinogenesis from adenomyomatosis, porcelain gallbladder and adenoma of the gallbladder. The surgical strategy and prognosis after surgery for GBC differ strikingly according to T-stage. Discrimination of favorable cases, particularly T2 or T3 lesions, is useful for the selection of surgical strategies for individual patients. Although many candidate factors predicting disease progression, such as depth of subserosal invasion, horizontal tumor spread, tumor budding, dedifferentiation, Ki-67 labeling index, p53 nuclear expression, CD8+ tumor-infiltrating lymphocytes, mitotic counts, Laminin-5-gamma-2 chain, hypoxia-inducible factor-1a, cyclooxygenase-2 and the Hedgehog signaling pathway have been investigated, useful prognostic makers or factors have not been established. As GBC is often discovered incidentally after routine cholecystectomy and accurate preoperative diagnosis is difficult, close mutual cooperation between surgeons and pathologists is essential for developing a rational surgical strategy for GBC.

Abstract
Gallbladder cancer is the fifth most common cancer involving gastrointestinal tract, but it is the most common malignancy of the biliary tract, accounting for 80-95% of biliary tract cancers. This tumor is a highly lethal disease with an overall 5-year survival of less than 5% and mean survival mere than 6 months. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis. The percentage of patients diagnosed to have gallbladder cancer after simple cholecystectomy for presumed gallbladder stone disease is 0.5-1.5%. Patients with preoperative suspicion of gallbladder cancer should not be treated by laparoscopy. Epidemiological studies have identified striking geographic and ethnic disparities-inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Improved imaging modalities and improved radical aggressive surgical approach in the last decade has improved outcomes and helped prolong survival in patients with gallbladder cancer. The overall 5-year survival for patients with gallbladder cancer who underwent R0 curative resection was from 21% to 69%. In the future, the development of potential diagnostic markers for disease will yield screening opportunities for those at risk either with ethnic susceptibility or known anatomic anomalies of the biliary tract.

Abstract
Gallbladder dysplasia and carcinoma (GBDC) vary greatly in incidence worldwide. We aimed to determine their prevalence in an Irish population, to assess the influence of tissue sampling protocols upon GBDC diagnosis, and to correlate various macroscopic and microscopic features with GBDC. We retrospectively reviewed histology reports of cholecystectomy specimens accessioned from 2000 to 2013. A total of 2522 cholecystectomy reports were reviewed, from 1860 female and 662 male patients. Male patients were significantly older (54.8 vs 46.8 years). There were 29 cases of dysplasia (1.15%) and 12 cases of carcinoma (0.48%), of which 10 were primary gallbladder cancers (0.4%). In 83.4% of cases, there was pathologic or radiologic evidence of cholelithiasis. Histologic findings included chronic (91.1%) or acute (15.4%) cholecystitis, cholesterosis (10.9%), adenomyomatous hyperplasia (2.1%), xanthogranulomatous inflammation (2.02%), and "porcelain" gallbladder (0.2%). Patients with GBDC were more likely to have a macroscopically identifiable lesion (29.4% vs 1.8%, positive predictive value, 18.18%, negative predictive value, 99.03%). Gallbladder dysplasia and carcinoma patients also had larger gallstones (median, 19 vs 12 mm) and were more likely to have adenomyomatous hyperplasia (8.8% vs 2.05%). When cases with a macroscopically identifiable lesion or clinical details suggestive of a gallbladder tumour were excluded (n = 2385), GBDC was significantly more frequently diagnosed if multiple tissue blocks had been sampled (2.91% vs 0.76%; relative risk (RR), 3.836). Rates of GBDC in Irish cholecystectomy specimens are low. The absence of a macroscopically identifiable lesion has a high (but not 100%) negative predictive value for GBDC. Sampling with more than 1 block significantly increases pickup rates of GBDC in these cases.

Abstract
Gallbladder cancer (GBC) is a lethal and a common malignancy affecting mostly females. There are restricted high incidence pockets across the world and in northern India highest incidence of GBC is reported from the Gangetic belt. The etiology of this disease remains largely unknown though several risk factors have been stated. The genetic aberrations in GBC involving mutations in tumor suppressor genes and oncogenes have been reported in literature. However, there is scarcity of data regarding epigenetic changes that may also be involved in gallbladder carcinogenesis. This review attempts to summarize our current understanding of the epigenetic changes in GBC.

Abstract
BACKGROUND Previous studies have suggested that diabetes mellitus (DM) is a risk factor for gallbladder cancer; however, it remains unclear whether DM with or without gallstones increases the risk of gallbladder cancer. The aim of this study was to evaluate the risk factors for gallbladder cancer, including sex, hypertension, hyperlipidemia, gallstones, and DM. METHODS The study cohort consisted of 214,179 subjects newly diagnosed with diabetes (cases) collected from the claims data of the Health Insurance Program of Taiwan from 2000 to 2001 who were retrospectively enrolled. The control group consisted of 206,860 subjects without diabetes, matched with the cases for sex, age, and index year. The subjects were followed up until the end of 2008. The effects of the risk factors on the incidence of gallbladder cancer were evaluated with Cox's proportional hazard regression models. RESULTS The risk of gallbladder cancer was higher in the DM group than in the non-DM group, with a hazard ratio (HR) of 1.53 [95 % confidence interval (CI) 1.22-1.90]. Gallstones were also a risk factor for gallbladder cancer, with an HR of 2.52 (95 % CI 1.11-5.73). DM and gallstones were synergistic risk factors for gallbladder cancer (p < 0.0001), with an HR of 5.37 (95 % CI 3.17-9.10) for subjects with both diseases in relation to those with neither of these conditions. CONCLUSIONS In the present long-term cohort study, DM with or without gallstones increased the risk of gallbladder cancer. Gallstones were independently related to gallbladder cancer, and DM and gallstones were synergistic risk factors for gallbladder cancer.

Abstract
Although gallbladder cancer (GBC) is the most common malignancy of the biliary tract, its relatively low incidence and confounding symptomatology result in advanced disease at the time presentation, contributing to the poor prognosis and decreased survival associated with this disease. It is therefore increasingly important to understand its pathogenesis and risk factors to allow for the earliest possible diagnosis. To date, gallbladder cancer is poorly understood compared to other malignancies, and is still most commonly discovered incidentally after cholecystectomy. Moreover, while much is known about biliary neoplasms as a whole, understanding the clinical and molecular nuances of GBC as a separate disease process will prove a cornerstone in the development of early intervention, potential screening and overall more effective treatment strategies. The present work reviews the most current understanding of the pathogenesis, diagnosis, staging and natural history of GBC, with additional focus on surgical treatment. Further, review of current adjuvant therapies for unresectable and advanced disease as well as prognostic factors provide fertile ground for the development of future studies which will hopefully improve treatment outcomes and affect overall survival for this highly morbid, poorly understood malignancy.

Abstract
BACKGROUND AND OBJECTIVES Discovery of incidental gallbladder cancer (IGC) has become more frequent due to adoption of laparoscopy. Gallbladder spillage during operation can disseminate cancer and worsen the prognosis. METHODS Patients who underwent laparoscopic or open cholecystectomy for benign gallbladder disease January 1996 to August 2011 at two tertiary care facilities were reviewed. Unmatched controls were randomly selected in 2:1 ratio. Preoperative variables were compared between the two groups. RESULTS Sixty-seven patients with IGC were identified and compared to 134 controls. Mean age was 68 for index cases and 49 for controls; 70% of cases and 75% of controls were female. Multivariate analysis showed that higher risk of IGC was significantly associated with age ≥ 65 (OR = 10.61, P < 0.0001), dilated bile ducts (OR = 4.76, P = 0.0028), and presence of gallbladder wall thickening (OR = 4.39, P = 0.0003). This model yielded a very good area under the curve of receiver operating characteristic (AUC = 0.83) for discriminating the patients with IGC from controls. CONCLUSIONS IGC is more likely to be found in patients when age is ≥65, with dilated bile ducts and gallbladder wall thickening. Preoperative suspicion of gallbladder cancer should prompt the surgeon to be more careful not to perforate the gallbladder during laparoscopic approach, and to have a lower threshold for conversion if necessary.

Abstract
Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.

Abstract
BACKGROUND While gallstones are associated with cancers of the gallbladder, the actual nature of their relationship needs to be clarified. This would aid the recommendations on the need for prophylactic cholecystectomy. METHODS A systematic search of the scientific literature was carried out using the Medline, the Embase, and the Cochrane Central Register of Controlled Trials for the years 1891-2009 to obtain access to all publications involving gallstones in gallbladder cancer. RESULTS While some epidemiological evidence supports a causal relationship for gallstones in gallbladder cancer, other studies have demonstrated a relatively low incidence of gallbladder cancer in countries reporting a high incidence of gallstones as a whole. In those studies where gallstones appear to have a causative role for cancer, the risk increases with increasing size, volume and weight, and number of the stones. The impact of duration of the stone or its composition is not clear. Experimental evidence from studies examining the impact of artificially introducing gallstones in the gallbladder has failed to lead to carcinogenesis. CONCLUSIONS The evidence at the current time indicates that gallstones are a cofactor in the causation of gallbladder cancer. Absolute proof of their role as a cause for gallbladder cancer is lacking. The recommendation for prophylactic cholecystectomy in countries reporting a high incidence of gallbladder cancer and associated gallstones needs to be tailored to the epidemiological profile of the place.

Abstract
AIM: To compare clinical presentation and ultrasound (US) and computed tomography (CT) sensitivity between intraluminal and infiltrating gallbladder carcinoma (GBCA).
METHODS: This retrospective study evaluated 65 cases of GBCA that were categorized morphologically into the intraluminal-GBCA (n = 37) and infiltrating-GBCA (n = 28) groups. The clinical and laboratory findings, presence of gallstones, gallbladder size, T-staging, nodal status, sensitivity of preoperative US and CT studies, and outcome were compared between the two groups.
RESULTS: There were no significant differences between the two groups with respect to female predominance, presence of abdominal pain, serum aminotransferases level, T2-T4 staging, and regional metastatic nodes. Compared with the patients with intraluminal-GBCA, those with infiltrating-GBCA were significantly older (65.49 ± 1.51 years vs 73.07 ± 1.90 years), had a higher frequency of jaundice (3/37 patients vs 13/28 patients) and fever (3/37 patients vs 10/28 patients), higher alkaline phosphatase (119.36 ± 87.80 IU/L vs 220.68 ± 164.84 IU/L) and total bilirubin (1.74 ± 2.87 mg/L vs 3.50 ± 3.51 mg/L) levels, higher frequency of gallstones (12/37 patients vs 22/28 patients), smaller gallbladder size (length, 7.47 ± 1.70 cm vs 6.47 ± 1.83 cm; width, 4.21 ± 1.43 cm vs 2.67 ± 0.93 cm), and greater proportion of patients with < 12 mo survival (16/37 patients vs 18/28 patients). The sensitivity for diagnosing intraluminal-GBCA with and without gallstones was 63.6% and 91.3% by US, and 80% and 100% by CT, respectively. The sensitivity for diagnosing infiltrating-GBCA with and without gallstones was 12.5% and 25% by US, and 71.4% and 75% by CT, respectively.
CONCLUSION: In elderly women exhibiting small gallbladder and gallstones on US, especially those with jaundice, fever, high alkaline phosphatase and bilirubin levels, CT may reveal concurrent infiltrating-GBCA.

Abstract
Gallbladder cancer (GBC) shows a marked geographical variation in its incidence, with the highest figures being seen in India and Chile and relatively low levels in many Western countries. Risk factors for its development include the presence of gallstones, infection and the presence of an anomalous pancreatobiliary ductal junction. It can arise from either a pathway involving metaplasia or dysplasia or one in which there is a pre-existing adenoma. The former is the more common and, because it is often not associated with a macroscopically recognizable lesion, leads to the recommendation that all gallbladders need to be examined microscopically. Accurate staging of invasive cancers is essential to determine prognosis and treatment, and this requires extensive tumour sampling. A number of genetic alterations have been identified in the preinvasive and invasive stages of GBC and they support the morphological evidence of there being two pathways by which tumours develop. Some of these genetic changes are associated with particular risk factors. For example, cases with anomalous pancreatobiliary ductal junction show a higher frequency of K-ras mutations. Some changes are associated with differences in prognosis. For example, cancers without expression of p21 but with expression for p27 have a better prognosis, whereas those that express c-erb-B2 have a worse one. Work has also been done on identifying clinical, imaging and other factors that indicate that patients have a higher risk of having GBC. This is particularly important in high-incidence areas in which GBC is a significant public health problem.

Abstract
AIM Gallbladder cancer is the fifth most common cancer involving the gastrointestinal tract, but it is the most common malignant tumour of the biliary tract worldwide. The percentage of patients diagnosed to have gallbladder cancer after simple cholecystectomy for presumed gallbladder stone disease is 0.5-1.5%. This tumour is traditionally regarded as a highly lethal disease with an overall 5-year survival of less than 5%. The marked improvement in the outcome of patients with gallbladder cancer in the last decade is because of the aggressive radical surgical approach that has been adopted, and improvements in surgical techniques and peri-operative care. This article aims to review the current approach to the management of gallbladder cancer. METHODS A Medline, PubMed database search was performed to identify articles published from 1990 to 2007 using the keywords 'carcinoma of gallbladder', 'gallbladder cancer', 'gallbladder neoplasm' and 'cholecystectomy'. RESULTS AND CONCLUSIONS The overall 5-year survival for patients with gallbladder cancer who underwent Ro curative resection was reported to range from 21% to 69%. Laparoscopic cholecystectomy is absolutely contraindicated when gallbladder cancer is known or suspected pre-operatively. Patients with a pre-operative suspicion of gallbladder cancer should undergo open exploration and cholecystectomy after proper pre-operative assessment. For patients whose cancer is an incidental finding on pathological review, a second radical resection is indicated except for Tis and T1a disease. There is still controversy for the optimal management of T1b disease. Although the role of surgery for advanced disease remains controversial, patients with advanced gallbladder cancer can benefit from radical resection, provided a potentially curative Ro resection is possible. There is still no effective adjuvant therapy for gallbladder cancer.

Abstract
BACKGROUND Radical surgery is the only curative treatment for carcinoma of gallbladder. This study aimed to evaluate the outcome of patients with carcinoma of gallbladder managed in a single institution over 16 years. METHODS From April 1988 to November 2003, 86 patients (29 males, 57 females) were diagnosed to have carcinoma of gallbladder. Tumor staging, treatment modalities and clinical outcome of these patients were evaluated. Thirty-two patients (37%) had early stage (TNM stage I or II) disease whereas 54 patients (63%) had advanced stage (TNM stage III or IV) disease. Curative treatment by surgical resection was performed in 23 patients (27%). RESULTS Overall survival was significantly better in patients with curative treatment (1-year: 85%; 2-year: 63%; 3-year: 55%) than those with palliative treatment (1-year: 11%; 2-year: 3%; 3-year: 0%; P < 0.01). Using Cox regression model, curative treatment was the only independent prognostic factor affecting overall survival of patients with carcinoma of gallbladder. A significantly better survival was associated with curative treatment compared with palliative treatment in patients with incidental gallbladder cancer. The median survival was 33.9 months for the curative treatment group versus 3 months for the palliative treatment group (P = 0.0001). CONCLUSION Favorable survival outcome can be achieved in patients with carcinoma of gallbladder after curative resection.

Abstract
Gallbladder cancer is one of the most lethal carcinomas and continues to pose many challenges for surgeons. Identifiable risk factors for carcinoma of the gallbladder include cholelithiasis, an anomalous pancreaticobiliary junction, and focal mucosal microcalcifications. Adenocarcinoma is the primary histologic type in most patients and the tumor is frequently associated with Kras and p53 mutations. Radiologic and endoscopic advances in endoscopic ultrasonography and magnetic resonance cholangiopancreatogram, plus helical computed tomography, have enhanced preoperative staging. Surgical options include cholecystectomy for disease limited to the mucosa (Tis/T1) or a radical cholecystectomy (subsegmental resection of segments IVB and V plus a hepatoduodenal ligament lymphadenectomy) for advanced disease without signs of distant metastasis (T2-4/N0-N2). Some surgeons have advocated more radical hepatic resection including extended right hepatectomy or central bisegmentectomy plus caudate lobectomy. Japanese surgeons have reported studies that included patients having a pancreaticoduodenectomy to improve distal ductal margins and lymphadenectomy for T3 and T4 cancers. These patients have a lower rate of local recurrence but no survival advantage. Options for adjuvant therapy remain limited. Radiation therapy with fluorouracil radiosensitization is the most commonly used postoperative treatments. Current trials are investigating the role of capecitabine, oxaliplatin, and bevacizumab in the management of gallbladder carcinoma.

Abstract
BACKGROUND Gallstones are considered the most important risk factor for gallbladder cancer. AIM To identify differences in the number, weight, volume, and density of gallstones associated with chronic cholecystitis (CC), gallbladder dysplasia (GD), and gallbladder cancer (GBC). METHODS A total of 125 cases were selected, of which 93 had gallstones associated with GBC and 31 had gallstones associated with GD. The controls were those with CC, matched by sex and age. The number, weight, volume, and density of these gallstones were examined in order to determine differences and relative cancer risk. RESULTS Number: Multiple gallstones were present in over 76% of cases (GBC and GD) and controls (P = ns). The average number of multiple stones was 21 in GBC versus 14 in controls (P < 0.01). Weight: The average weight of the gallstones was 9.6 g in GBC versus 6.0 g in controls (P = 0.0004). The average weight in multiple stones over 10 g had strong association with GBC (P = 0.0006). Volume: The average volume was 11.7 and 6.48 ml in GBC and controls (P = 0.0002). Average volumes of 6, 8, and 10 ml had a relative cancer risk of 5, 7, and 11 times, respectively. Size: No differences were shown between GBC, GD, and controls. CONCLUSIONS The volume of gallstones associated with other risk factors of GBC may be helpful in prioritizing cholecystectomies in symptomatic patients.

Abstract
Silent (asymptomatic) gallstones are detected frequently with the widespread use of abdominal ultrasonography. The presence of gallstones is found strongly associated with gallbladder carcinoma. Studies on the natural history and most decision analysis studies do not favor prophylactic cholecystectomy for patients with silent gallstones. Gallbladder carcinoma is known to be highly aggressive and lethal disease with a poor outcome. It is rarely diagnosed early and only 10-30% patients are offered radical surgery on presentation. This has lead to a dilemma leading most surgeons to opt for an expectant management of silent gallstones. It thus raises the important question of the implications of leaving asymptomatic gallstones untouched. In this paper the author has reviewed the current understanding on silent gallstones and gallbladder carcinoma.

Abstract
Gallbladder cancer (GBC) is the most common biliary tract malignancy. There is a tremendous regional variability in its incidence. Risk factors include genetic susceptibility, gender, presence of gallstones, chronic biliary infections, diet and some anatomical anomalies. Several genetic abnormalities have been described which may be aetiologically important as well as carry prognostic significance. These include mutations in the proteins K-RAS and P53, and altered expression of P-glycoprotein, COX-2 and epidermal growth factor receptor. Most patients present at an advanced stage, overall prognosis is very poor. TNM stage and the extent of surgical resection are the most important prognostic factors. Surgery is the only curative therapy reserved for patients with early-stage disease. The role of adjuvant therapy is not fully defined. Patients with advanced disease are managed with systemic chemotherapy that is primarily palliative. Although 5-fluorouracil alone, or in combination, has been most commonly utilised, there is much greater enthusiasm for the combination of cisplatin and gemcitabine. The availability of better drugs and combinations may affect the use of chemotherapy in neoadjuvant and adjuvant settings. Novel targeted therapies require exploration alone or in combination with chemotherapy.
