Abstract
An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists was convened on 15 January 2014 to review current evidence on the management of gallbladder carcinoma in order to establish practice guidelines. In summary, within high incidence areas, the assessment of routine gallbladder specimens should include the microscopic evaluation of a minimum of three sections and the cystic duct margin; specimens with dysplasia or proven cancer should be extensively sampled. Provided the patient is medically fit for surgery, data support the resection of all gallbladder polyps of >1.0 cm in diameter and those with imaging evidence of vascular stalks. The minimum staging evaluation of patients with suspected or proven gallbladder cancer includes contrasted cross-sectional imaging and diagnostic laparoscopy. Adequate lymphadenectomy includes assessment of any suspicious regional nodes, evaluation of the aortocaval nodal basin, and a goal recovery of at least six nodes. Patients with confirmed metastases to N2 nodal stations do not benefit from radical resection and should receive systemic and/or palliative treatments. Primary resection of patients with early T-stage (T1b-2) disease should include en bloc resection of adjacent liver parenchyma. Patients with T1b, T2 or T3 disease that is incidentally identified in a cholecystectomy specimen should undergo re-resection unless this is contraindicated by advanced disease or poor performance status. Re-resection should include complete portal lymphadenectomy and bile duct resection only when needed to achieve a negative margin (R0) resection. Patients with preoperatively staged T3 or T4 N1 disease should be considered for clinical trials of neoadjuvant chemotherapy. Following R0 resection of T2-4 disease in N1 gallbladder cancer, patients should be considered for adjuvant systemic chemotherapy and/or chemoradiotherapy.

Abstract
PURPOSE Recommendation for management of gallbladder polyps (GBPs) >1 cm is cholecystectomy. No consensus exists on management of GBPs <1 cm. This systematic review examines current evidence on management of GBPs. METHODS MEDLINE, EMBASE and Cochrane library databases were searched from January 1991 to June 2013 using specified terms. A predefined protocol for data extraction was used to retrieve specified end points. RESULTS Literature search yielded 43 manuscripts with a dataset of 11,685 patients with GBPs. M:F ratio was 1.3:1. Average age (range) was 49 years (32-83). Patients with malignant GBPs had an average (range) age of 58 (50-66) years with M:F ratio of 0.78:1. Cholesterol polyps constituted 60.5% of GBPs followed by adenomas (15.2%) and cancer (11.6%). Malignant GBPs ≥1 cm, <1 cm and <5 mm constituted 8.5, 1.2 and 0% of GBPs, respectively. Majority of patients requiring surgical intervention had laparoscopic cholecystectomy. CONCLUSIONS Presently employed policy of cholecystectomy for GBPs >1 cm is appropriate. For GBPs <1 cm, the authors propose (accepting existence of differing proposals) the following: 1. Surveillance may not be needed for GBPs <5 mm. 2. For GBPs between 5 and 10 mm, two scans at six monthly intervals is suggested and after that, tailor surveillance to age, growth and ethnicity. In the non-Asian population, if GBP remains the same size or number, discontinuation of surveillance may be considered. In the Asian population, if GBPs remain the same, yearly surveillance is continued for a suggested period of 3 years. 3. Discontinue surveillance if GBPs is/are smaller/ disappeared. Cholecystectomy is advised where size increases to >10 mm.

Park HY, Oh SH, Lee KH, Lee JK, Lee KT. Is cholecystectomy a reasonable treatment option for simple gallbladder polyps larger than 10 mm? World J Gastroenterol 2015; 21:4248-4254. [PMID: 25892875 PMCID: PMC4394086 DOI: 10.3748/wjg.v21.i14.4248] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2014] [Revised: 09/22/2014] [Accepted: 12/01/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To determine the relevance of the 10-mm size criterion of the generally accepted surgical indication for gallbladder polyps (GBPs).
METHODS: We collected data of patients who were confirmed to have GBPs through cholecystectomy at Samsung Medical Center between January 1997 and December 2012. Among the patients who underwent cholecystectomy for GBP, those with a definite evidence for malignancy such as adjacent organ invasion, metastasis on preoperative imaging studies, polyp larger than 20 mm, absence of preoperative imaging study results, and patients having gallstones were excluded. We retrospectively collected and analyzed information on patient’s clinical characteristics, symptoms, ultrasonographic findings, and blood laboratory tests.
RESULTS: A total of 836 patients who had undergone cholecystectomy were retrospectively analyzed. Seven hundred eighty patients (93%) had benign polyps, whereas 56 patients (7%) had malignant polyps. Of the 56 patients with malignancy, 4 patients (7%) had borderline GBP (10-12 mm) and a patient had small GBP (< 10 mm) with T2 stage. We conducted an ROC curve analysis to verify the 10-mm size criteria (AUC = 0.887, SD = 0.21, P < 0.001). In the ROC curve for polyp size and malignancy, sensitivity and specificity of the 10-mm size criterion was 98.2% and 19.6%, respectively. The specificity of the 11-mm and 12-mm size criteria was 44.6% and 56%, respectively, whereas the sensitivity of these two size criteria was similar. We defined the GBPs of 10 to 12 mm as a borderline-sized GBP, which were found in 411 patients (49%). In this group, there was a significant difference in age between patients with benign and malignant GBPs (47 years vs 60 years, P < 0.05).
CONCLUSION: GBPs larger than 13 mm need immediate excision whereas for borderline-sized GBPs detected in young patients, careful medical observation can be a rational decision.

Abstract
We present an unusual case of a 75-year-old woman, with no significant medical history, presenting with ongoing weight loss and change in bowel habit. Her physical examination and initial blood tests were all normal, and, therefore, radiographic imaging was undertaken. Ultrasound and CT of the abdomen confirmed a gallbladder polyp and a laparoscopic cholecystectomy was subsequently performed. Histological analysis confirmed primary gallbladder lymphoma. This case report is the first to present gallbladder lymphoma presenting as a polyp. The authors discuss the incidence, presentation and management of gallbladder lymphoma.

Growth rate and malignant potential of small gallbladder polyps--systematic review of evidence. Surgeon 2014; 12:221-6.

Abstract
THE BACKGROUND AND PURPOSE The overall aim of this systematic review was to determine whether ultrasound (US) follow up for gallbladder polyps (GBPs) measuring less than 10 mms is necessary. METHODS A search was performed in MEDLINE and EMBASE between January 1976 and January 2012 using keywords: gallbladder, polyps, neoplasm, cancer, tumour, carcinoma, malignant, adenoma. Included were studies involving adult patients, examined with transabdominal US at least twice. The outcomes of included studies were gallbladder polyp growth as demonstrated on US over time, followed where available by histological examination of cholecystectomy specimens. MAIN FINDINGS Ten studies met the inclusion criteria for the review. Altogether 1958 subjects with mean age between 41.5 and 59 years were followed up with US. The percentage of GBPs which showed growth over the follow up period ranged from 1% to 23%. 43 neoplastic polyps were found in total irrespective of size, 20 of which were malignant and at least 7 of those were >10 mms. At least 7 malignancies were present in polyps <10 mms but it was unknown if they had undergone growth on follow up. CONCLUSIONS Level II-2 and below evidence on rate of growth of small GBPs <10 mms exists in the literature. It indicates that growth does occur in a significant minority of small GBPs, but it is slow. Due to deficient reporting and small numbers of cases, the correlation between growth of GBP and development of malignancy cannot be established using currently available evidence. Malignancy can be present in polyps <10 mms although it is significantly more frequent in polyps >10 mms. Cholecystectomy for symptomatic GBPs irrespective of their size, alongside the current practice for removal of gall bladders containing asymptomatic polyps >10 mms, is proposed. No evidence based US follow up schedule can be recommended at present for asymptomatic polyps <10 mms, and in its absence an intuitive follow up with US is likely to continue.

Abstract
The association between gallbladder polyps (GBP) and gallbladder cancer (GBC) is unclear. We sought to determine the association between preoperative diagnosis of GBP on imaging and GBC. A retrospective review of patients over 9 years was conducted using International Classification of Diseases, 9th Revision codes for GBP and GBC who underwent cholecystectomy at our institution. Demographics, imaging findings, and pathology results were recorded. A total of 2416 patients underwent cholecystectomy during the study period. Twenty-seven had an operation for GBP either as a result of concern for size or symptoms. Polyp sizes were categorized as less than 1 cm, 1 to 2 cm, or 2 cm or greater. Twenty-four patients in this group (88.9%) had no evidence of high-grade dysplasia or cancer and all of these benign polyps were 2 cm or less on imaging. One patient with a 2.4-cm polyp had high-grade dysplasia, and two patients with polyps over 3 cm had adenocarcinoma. During the same period, 20 patients had an operation for GBC with two patients common to the polyp group. The group of patients with noncancerous polyps was significantly younger than the cancer group (polyps and no polyps). The cancer group was more likely to be symptomatic. Therefore, polyps over 2 cm should be removed given the risk of high-grade dysplasia and cancer above this size. Polyps less than 2 cm were not associated with high-grade dysplasia or cancer and thus surgery may not be required. Intermediate- and small-sized polyps can be monitored with serial ultrasound, especially in younger, asymptomatic patients in whom the risk of malignancy is low.

Abstract
AIM: To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China.
METHODS: All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invited to have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted.
RESULTS: A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of post-cholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P < 0.001). The analyzed risk factors with increased OR for the development of PLGs were male gender (OR = 1.799, P < 0.001), age ≥ 30 years (OR = 2.699, P < 0.001) and hepatitis B surface antigen (HBsAg) positivity (OR = 1.374, P = 0.006).
CONCLUSION: PLGs are not rare among Chinese petrochemical employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs.

Abstract
Gallbladder cancer is a rather uncommon disease, when it gives symptoms it has usually reached an incurable stage. Therefore, every attempt must be made to find the asymptomatic stages and look for premalignant gallbladder polyps. Even if gallbladder cancer is a rare disease, gallbladder polyps are common, only a few polyps develop to cancer. This makes gallbladder polyps another problem: which are the polyps that must be surgically removed, which shall be followed-up, or for how long? The author used the keyword “gallbladder polypsn” in PubMed and reviewed the scientific literatures published from January 2000 to December 2011. The present review article has summarized almost all respects of gallbladder polyp, including the risk factors, clinical diagnosis and management, and comments made from the author, in which clinical treatments are recommended. It is author's purpose that the 11-year-knowledge about gallbladder polyps summarized from all worlds’ literatures is enough to know how clinicians will handle the next patient with gallbladder polyp.

Abstract
OBJECTIVES The increase in the routine use of abdominal imaging has led to a parallel surge in the identification of polypoid lesions in the gallbladder. True gallbladder polyps (GBP) have malignant potential and surgery can prevent or treat early gallbladder cancer. In an era of constraint on health care resources, it is important to ensure that surgery is offered only to patients who have appropriate indications. The aim of this study was to assess treatment and surveillance policies for GBP among hepatobiliary and upper gastrointestinal tract surgeons in the UK in the light of published evidence. METHODS A questionnaire on the management of GBP was devised and sent to consultant surgeon members of the Association of Upper Gastrointestinal Surgeons (AUGIS) of Great Britain and Ireland with the approval of the AUGIS Committee. It included eight questions on indications for laparoscopic cholecystectomy and surveillance based on GBP (size, number, growth rate) and patient (age, comorbidities, ethnicity) characteristics. RESULTS A total of 79 completed questionnaires were returned. The vast majority of surgeons (>75%) stated that they would perform surgery when a single GBP reached 10 mm in size. However, there was a lack of uniformity in the management of multiple polyps and polyp growth rate, with different surveillance protocols for patients treated conservatively. CONCLUSIONS Gallbladder polyps are a relatively common finding on abdominal ultrasound scans. The survey showed considerable heterogeneity among surgeons regarding treatment and surveillance protocols. Although no randomized controlled trials exist, national guidelines would facilitate standardization, the formulation of an appropriate algorithm and appropriate use of resources.

Abstract
BACKGROUND Possible mass lesions identified on ultrasound (US) of the gallbladder may prompt an aggressive surgical intervention due to the possibility of a malignant neoplasm. AIM This study aims to utilize a large modern series of patients with gallbladder lesions identified on US to evaluate imaging characteristics consistent with malignancy. METHODS A retrospective review was conducted of gallbladder ultrasound reports and clinicopathologic data of patients with a mass identified on US. RESULTS Approximately 59,271 abdominal ultrasounds and 9,117 cholecystectomies were performed between February 2000 and February 2010. We identified 213 patients with a questionable gallbladder neoplasm on ultrasonography who underwent surgical exploration. Median age was 52 years (range=11-87 years) and 147 (69%) were females. Final pathology demonstrated no neoplasm in 130 patients (61%), while 32 patients (15%) had a wall adenomyoma, 36 (17%) had a polyp (five of which were malignant), 14 (7%) had an adenocarcinoma not arising from a polyp, and one patient had a cystic papillary neoplasm. The smaller the lesion, the more likely it was to be a pseudo-mass. For lesions measuring <5 mm on US, 83% had no lesion found on final pathology. Significant predictors of malignancy were age >52 years (p<0.001), presence of gallstones on US (p=0.004), size >9 mm (p<0.001), evidence of invasion at the liver interface (p<0.001), and wall thickening >5 mm (p<0.001). Shape (sessile or penduculated), echogenicity (echogenic or isoechoic), or presence of flow on Doppler were not predictors of malignancy. An US size of ≤ 9 mm had a negative predictive value of 100% for malignancy. CONCLUSIONS Despite improvements in imaging, most apparent lesions measuring <5 mm on US are not identified in the surgical specimen. US size >9 mm, age >52 years, US suggestion of invasion at the liver interface, and wall thickening >5 mm, especially in the presence of gallstones, should raise the suspicion of malignancy.

Abstract
Carcinoid tumor of the gallbladder is a rare tumor which comprises less than 0.5% of all human carcinoid tumors. We present a case of primary carcinoid tumor of the gallbladder in a 57-year-old woman with a chief complaint of polypoid lesions of the gallbladder over ten years. The tumor measured 1.5 cm× 1 cm × 0.9 cm and was located in the neck of the gallbladder. Histologically, the tumor showed features of classical carcinoid, and tumor cells were positive for synapsin and chromogranin A. The tumor occurred on a background of cholesterol polyps. Based on published data, we did a comprehensive literature review of carcinod tumor of the gallbladder. This is the first case of primary carcinoid tumor of the gallbladder that occurred after the presence of cholesterol polyps over 10 years.

Abstract
PURPOSE To determine the natural history of gallbladder (GB) polyps incidentally detected at ultrasonography (US) and to propose management guidelines for these lesions based on polyp size. MATERIALS AND METHODS The HIPAA-compliant study was approved by the institutional review board, and informed consent was waived. A database search for "polyp" in all US examinations of the GB between January 1, 1999, and December 31, 2001, at a single institution was performed. All subsequent US reports were reviewed to determine changes in GB polyp size. The electronic medical record was searched to obtain clinical and pathologic follow-up. RESULTS Three hundred forty-six patients (mean age, 51.6 years; range, 20-93 years) with GB polyps were included. There were 156 men (45%) and 190 women (55%). US follow-up (mean, 5.4 years; range, 2-11.5 years) was performed in 149 patients (43%). Polyp size was stable in 90 (60%) polyps, decreased in eight (5%), increased in one (1%), and resolved in 50 (34%). Forty-two patients (12%) underwent cholecystectomy, revealing 13 (31%) GBs with polypoid lesions, 24 (57%) with stones and no polyps, and five (12%) with neither a stone nor a polypoid lesion. Clinical follow-up (mean, 8 years; range, 5-10.4 years) was performed in 155 patients (45%). No patient had clinical evidence of GB-related disease. Overall, no cases of GB malignancy were identified in 346 patients. Mean polyp size was 5.0 mm (range, 1-18 mm). No neoplastic polyps were found at 1-6 mm, one neoplastic polyp was seen at 7-9 mm, and two neoplastic polyps were found at 10 mm or larger. CONCLUSION The risk of GB malignancy resulting from incidentally detected polyps is extremely low. Incidentally detected GB polyps measuring 6 mm or less may require no additional follow-up. Data are inconclusive regarding polyps 7 mm or greater, and further studies are warranted.

Abstract
Gallbladder polyps are frequently encountered on cross-sectional imaging, often in asymptomatic patients. Most are benign and of little clinical importance. However, some polyps do have a malignant potential. This article discusses the clinical presentation, diagnosis, and natural history of gallbladder polyps and risk factors for malignant polyps and indications for cholecystectomy.

Abstract
The polypoid lesions of gallbladder have explosively increased with enhanced feasibility of transabdominal ultrasonography. Most of small polyps less than 10 mm are benign and remain static for a long period. In small polyps, three to six month intervaled ultrasonography is warranted in the initial follow-up, but the duration of follow-up period is not clarified. The polypoid lesions larger than 10 mm show a quite different feature. They showed a remarkable risk of malignancy (34-88%) and should be treated by surgery. Furthermore, age more than 50 years and combined gallstone are important factors predicting malignancy in polypoid lesions of gallbladder. In addition, other factors including solitary polyp and the presence of symptoms are considered as risk factors. Laparoscopic cholecystectomy is a golden standard therapy for these polyps unless the suspicion of malignancy is high. The gallbladder polyps remain a problem of concern to both doctors and patient with the worry of malignancy. Thus, the comprehensive understanding of natural coruse of gallbladder polyp and risk factors of malignancy should be kept in mind.
