Abstract
INTRODUCTION AND IMPORTANCE Gallbladder Adenomyomatosis (GA) is a benign rare condition that is mostly asymptomatic but can present as abdominal pain. GA usually occurs in the middle-aged population with an equal sex distribution. CASE PRESENTATION A case of a 49-years-old female who sought medical care several times due to abrupt abdominal pain. She underwent echography, Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) before performing laparoscopic cholecystectomy for symptomatic GA. The pathology report confirmed acalculous cholecystitis in the presence of GA. CLINICAL DISCUSSION In fact, echography can reveal the "comet- tail" sign, the CT can show the "rosary sign"; and MRI shows the "pearl necklace" sign. These signs, in the absence of gallstones, can justify the abdominal pain hence the diagnosis of symptomatic GA. CONCLUSION GA is being increasingly reported; however, symptomatic cases remain the exception. We believe that awareness to this entity should be raised so that healthcare professionals can establish the diagnosis efficiently.

Abstract
Radiologists across many imaging modalities commonly encounter gallbladder adenomyomatosis. The classic imaging appearances of gallbladder adenomyomatosis are well described and confirm benignity. However, in clinical practice, adenomyomatosis can be challenging to differentiate from other gallbladder pathologies that require cholecystectomy. In this article, we describe the common and uncommon appearances of gallbladder adenomyomatosis on multimodality imaging, helping differentiate adenomyomatosis from non-benign gallbladder abnormalities. Accurately differentiating adenomyomatosis from its mimics provides the surgical team with important clinical and surgical management information, improving patient outcomes.

Abstract
Objectives Adenomyomatosis (ADM) of the gallbladder is a benign condition, which is characterized by mucosal hyperplasia of the gallbladder and formation of intramucosal invagination through the thickened mucosal layer. The pathogenesis is unclear. This condition is rare in children. The aim of this publication is to present the case of a teenager with ADM of the gallbladder and review the pediatric literature on this topic. Methods A 17-year-old female presented with severe postprandial right upper quadrant abdominal pains. The abdominal ultrasound revealed ADM of the gallbladder. Results A curative laparoscopic cholecystectomy was performed. Since 1998, eleven of the 13 pediatrics cases reported with ADM of the gallbladder were symptomatic and a cholecystectomy was curative in all of them. Conclusion ADM of the gallbladder should be considered in the differential diagnosis of recurrent right abdominal upper quadrant pains in pediatrics. Abdominal ultrasound is the best diagnostic procedure. In symptomatic patients, a cholecystectomy is curative.

Xanthogranulomatous cholecystitis in a patient with ulcerative colitis and primary sclerosing cholangitis: A case report. Radiol Case Rep 2023; 18:3513-3521.

Abstract
Chronic gallbladder disease due to xanthogranulomatous cholecystitis is uncommon, and its symptoms are generally vague. While there is no firm evidence to link xanthogranulomatous cholecystitis to primary sclerosing cholangitis or ulcerative colitis. The patient is a 41-year-old male with a history of ulcerative colitis, primary sclerosing cholangitis, and biliary stenting who complained of symptoms of anorexia, jaundice, and pruritus. In the initial ultrasound exam, there was evidence of intrahepatic and extra-hepatic bile duct dilation along with a significant and mass-like circumferential thickening of the gallbladder wall. Magnetic resonance cholangiopancreatography was performed for further evaluation, which indicated increased gallbladder wall thickness, containing multiple T2 hyper-signal nodules while the mucosal layer was intact. There was also a filling defect in the common bile duct's distal portion. These findings matched a xanthogranulomatous cholecystitis diagnosis and a possibly malignant lesion in the distal of the common bile duct. The patient ultimately had a cholecystectomy, and pathology findings confirmed the diagnosis of xanthogranulomatous cholecystitis. Biopsy specimens obtained from the distal of the common bile duct lesion were microscopically identified as intramucosal adenocarcinoma. In patients with a history of primary sclerosing cholangitis who present with nonspecific symptoms suggesting chronic gallbladder disease and radiologic evidence of circumferential gallbladder wall thickening containing intramural nodules and intact mucosa, xanthogranulomatous cholecystitis should be kept in mind.

Abstract
Nowadays, despite all the conducted research and the provided efforts in advancing the healthcare sector, there is a strong need to rapidly and efficiently diagnose various diseases. The complexity of some disease mechanisms on one side and the dramatic life-saving potential on the other side raise big challenges for the development of tools for the early detection and diagnosis of diseases. Deep learning (DL), an area of artificial intelligence (AI), can be an informative medical tomography method that can aid in the early diagnosis of gallbladder (GB) disease based on ultrasound images (UI). Many researchers considered the classification of only one disease of the GB. In this work, we successfully managed to apply a deep neural network (DNN)-based classification model to a rich built database in order to detect nine diseases at once and to determine the type of disease using UI. In the first step, we built a balanced database composed of 10,692 UI of the GB organ from 1782 patients. These images were carefully collected from three hospitals over roughly three years and then classified by professionals. In the second step, we preprocessed and enhanced the dataset images in order to achieve the segmentation step. Finally, we applied and then compared four DNN models to analyze and classify these images in order to detect nine GB disease types. All the models produced good results in detecting GB diseases; the best was the MobileNet model, with an accuracy of 98.35%.

Abstract
BACKGROUND Hepatobiliary scintigraphy (HBS) is a useful diagnostic imaging technique that uses radiotracers to evaluate the function of the gallbladder (GB) and biliary system. In segmented GB, some HBS images reveal a discordant GB boundary as compared to anatomical images.
AIM To evaluate the characteristics of HBS in segmented GB and determine the clinical relevance according to HBS characteristics.
METHODS A total of 268 patients with chronic cholecystitis, gallstones, or biliary colic symptoms who underwent HBS between 2011 and 2020 were enrolled. Segmented GB was defined as segmental luminal narrowing of the GB body on computed tomography (CT) or magnetic resonance (MR) images, and HBS was examined 1 mo before or after CT or MR. Segmented GB was classified into 3 types based on the filling and emptying patterns of the proximal and distal segments according to the characteristics of HBS images, and GB ejection fraction (GBEF) was identified: Type 1 was defined as a normal filling and emptying pattern; Type 2 was defined as an emptying defect on the distal segment; and Type 3 was defined as a filling defect in the distal segment.
RESULTS Segmented GB accounted for 63 cases (23.5%), including 36 patients (57.1%) with Type 1, 18 patients (28.6%) with Type 2, and 9 patients (14.3%) with Type 3 emptying pattern. Thus, approximately 43% of HBS images showed a discordant pattern as compared to anatomical imaging of segmented GB. Although there were no significant differences in clinical symptoms, rate of cholecystectomy, or pathological findings based on the type, most gallstones occurred in the distal segment. Reported GBEF was 62.50% ± 24.79% for Type 1, 75.89% ± 17.21% for Type 2, and 88.56% ± 7.20% for Type 3. Type 1 showed no difference in reported GBEF compared to the non-segmented GB group (62.50% ± 24.79% vs 67.40% ± 21.78%). In contrast, the reported GBEF was higher in Types 2 and 3 with defective emptying and filling when compared to Type 1 (80.11% ± 15.70% vs 62.57% ± 24.79%; P = 0.001).
CONCLUSION In segmented GB, discordance in the filling patterns detected by HBS and anatomical imaging could lead to misinterpretation of GBEF. For this reason, clinicians should be cautious when interpreting HBS results in patients with segmented GB.

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
BACKGROUND Cholecystectomy is routinely performed during living donor hepatectomy both to see the structure of the biliary tract and to determine the demarcation line based on the biliary tract junction. This study aims to present the general histopathological features of the gallbladder specimen obtained from living liver donors (LLD). METHODS Data from 2577 LLDs who underwent living donor hepatectomy (n = 2511) or aborted living donor hepatectomy (n = 66) in our Liver Transplantation Institute between September 2005 and June 2021 were analyzed retrospectively. Age, gender, macroscopic (length, diameter, and wall thickness), and microscopic (histopathological) features of the gallbladder of the LLDs were recorded for use in this study. RESULTS A total of 2493 LLDs (men: 1486, women: 1007) with a median age of 29 years (interquartile range [IQR]: 13) met the inclusion criteria in this study. The median length, width and wall thickness of the gallbladder specimens were measured as 70 mm (IQR: 20), 50 mm (IQR: 20), and 2 mm (IQR: 1), respectively. The most common histopathological findings are normal structure (2026; 81.3%), chronic cholecystitis (n = 446; 17.9%), adenomyomatosis (n = 9), and papillary hyperplasia (n = 6), respectively. The most common pathologic findings in the gallbladder lumen are cholesterolosis (n = 207; 0.4%), cholelithiasis (n = 53), cholesterol polyp (n = 31), and noncholesterol polyp (n = 19), respectively. Significant differences were detected between the male and female genders in terms of age (P < .001), height (P < .001), weight (P < .001), body mass index (P < .001), gallbladder width (P = .001), gallbladder length (P < .001), histopathological finding (content) (P < .001), and lymph node around the gallbladder (P = .015). CONCLUSIONS The results we obtained in this study are true gallbladder pathologies that can be detected in healthy people. In this study, it was shown that the diameter and size of the gallbladder were larger in men, whereas the incidence of cholesterolosis and cholelithiasis was higher in women.

Abstract
Amaç: Safra kesesi adenomyomatozisinin (SKA) kesin patogenezi hala tam olarak açıklanamamıştır, tanı ve tedavisine ilişkin bazı tartışmalar mevcut. Başlangıçta kanser öncesi bir lezyon olarak kabul edilen adenomyomatozis, son zamanlarda yapılan çalışmalarda safra kesesinin sıklıkla kolesistit ve kolelitiazis ile ilişkili iyi huylu bir değişikliği olarak kabul edilmektedir. Bu çalışmada, SKA patogenezini araştırmak için; aynı hastada safra kesesi normal ve adenomyomatozis dokusunda, tümör hücrelerinin proliferatif aktivitesini gösteren biyobelirteç düzeyleri ve neoplastik doku pozitiflik paternini gösteren biyobelirteç düzeylerinin karşılaştırılması amaçlanmıştır.Yöntem: 2019-2020 yılları arasında toplam 750 laparoskopik kolesistektomi uygulanan hastanın patoloji raporları incelenmiş, adenomyomatozis tanısı alan 20 vaka retrospektif olarak değerlendirilmiştir. Proliferasyon belirteci olarak Ki-67 ve neoplastik aktivite belirteci olarak P53, safra kesesi normal dokusu ile adenomyomatozis dokusunda ayrı ayrı değerlendirilmiştir.Bulgular: Safra kesesi normal ve adenomyomatozis dokusundaki Ki-67 indeksi ortalama değerleri karşılaştırıldığında, istatistiksel olarak anlamlı fark bulundu (p<0,000). Ancak bu iki grup P53 indeksi ortalama değerleri açısından karşılaştırıldığında istatistiksel fark bulunamadı (p=0,062).Sonuç: Çalışmada adenomyomatozis dokularında anlamlı derecede yüksek Ki-67 proliferasyon belirteci düzeyleri tespit edilmesine karşın, safra kesesi kanserinin yaygın P53-pozitiflik paterninin bu dokularda normal dokularla karşılaştırıldığında anlamlı farklar saptanmaması, SKA’nin kanser öncüsü bir lezyon olmayıp, iyi huylu proliferatif bir değişiklik olduğunu destekler görünmektedir.

Abstract
Background Chronic cholecystitis is inflammation of the gall bladder usually caused by stones. The aim was to find out the prevalence of mucocele and empyema in chronic cholecystitis using cholecystectomy findings and histopathological reports. Methodology This was a cross-sectional observational study conducted in Surgical Ward 1, Jinnah Postgraduate Medical Center, Karachi from December 2019 to December 2021 for two years. Patients above 12 years of age diagnosed with chronic cholecystitis with cholelithiasis on clinical examination and investigations were included. Patients who were diagnosed with acute cholecystitis, mucocele, or empyema on clinical examination and ultrasonography were excluded from the study. Laparoscopic cholecystectomy was done and operative findings were noted. Gall bladder specimens were examined for mucocele and empyema and were sent for histopathology. Results were recorded and analyzed. Results There were 241 patients diagnosed with chronic cholecystitis with cholelithiasis on clinical examination and investigations. On examination, tenderness in the right hypochondrium was absent in all patients. Chronic cholecystitis was proved on histopathology in 231 patients (95.85%). Other findings diagnosed on peroperative findings and histopathology reports were strawberry gall bladder (2.41%), empyema (0.83%), mucocele (0.41%), and polyp (0.41%). Two hundred eight patients were female (86.31%), 33 were male(13.69%). The male to female ratio was 1:6.43. The average age was 31 years. Conclusion Inflammation and fibrosis of the gallbladder around Calot’s triangle increase the chances of vascular and common bile duct injury. In such cases, cholecystectomy can become difficult. It was concluded that empyema, mucocele, and strawberry gall bladder could be found in chronic cholecystitis, and cholecystectomy becomes difficult in such cases.

Abstract
Rokitansky-Aschoff sinuses (RAS) are a common imaging finding in gallbladder adenomyomatosis (ADM), often presenting as fundal cystic spaces. Intracholecystic papillary neoplasm (ICPN) is a relatively uncommon pre-invasive tumor of the gallbladder epithelium that rarely involves RAS mucosa. We compare two cases that showed similar fundal cystic spaces resembling RAS, in which Magnetic Resonance Diffusion-Weighted Imaging (MR-DWI) was valuable for detecting (or ruling out) an underlying malignant ICPN. Evidence from the literature overall supports the role of MR-DWI for detecting intracholecystic malignant tissue.

[PMID: 34918177 PMCID: PMC9038818 DOI: 10.1007/s00330-021-08384-w] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 10/04/2021] [Accepted: 10/06/2021] [Indexed: 12/16/2022]
Abstract
Abstract Main recommendations Primary investigation of polypoid lesions of the gallbladder should be with abdominal ultrasound. Routine use of other imaging modalities is not recommended presently, but further research is needed. In centres with appropriate expertise and resources, alternative imaging modalities (such as contrast-enhanced and endoscopic ultrasound) may be useful to aid decision-making in difficult cases. Strong recommendation, low–moderate quality evidence. Cholecystectomy is recommended in patients with polypoid lesions of the gallbladder measuring 10 mm or more, providing the patient is fit for, and accepts, surgery. Multidisciplinary discussion may be employed to assess perceived individual risk of malignancy. Strong recommendation, low-quality evidence. Cholecystectomy is suggested for patients with a polypoid lesion and symptoms potentially attributable to the gallbladder if no alternative cause for the patient’s symptoms is demonstrated and the patient is fit for, and accepts, surgery. The patient should be counselled regarding the benefit of cholecystectomy versus the risk of persistent symptoms. Strong recommendation, low-quality evidence. If the patient has a 6–9 mm polypoid lesion of the gallbladder and one or more risk factors for malignancy, cholecystectomy is recommended if the patient is fit for, and accepts, surgery. These risk factors are as follows: age more than 60 years, history of primary sclerosing cholangitis (PSC), Asian ethnicity, sessile polypoid lesion (including focal gallbladder wall thickening > 4 mm). Strong recommendation, low–moderate quality evidence. If the patient has either no risk factors for malignancy and a gallbladder polypoid lesion of 6–9 mm, or risk factors for malignancy and a gallbladder polypoid lesion 5 mm or less, follow-up ultrasound of the gallbladder is recommended at 6 months, 1 year and 2 years. Follow-up should be discontinued after 2 years in the absence of growth. Moderate strength recommendation, moderate-quality evidence. If the patient has no risk factors for malignancy, and a gallbladder polypoid lesion of 5 mm or less, follow-up is not required. Strong recommendation, moderate-quality evidence. If during follow-up the gallbladder polypoid lesion grows to 10 mm, then cholecystectomy is advised. If the polypoid lesion grows by 2 mm or more within the 2-year follow-up period, then the current size of the polypoid lesion should be considered along with patient risk factors. Multidisciplinary discussion may be employed to decide whether continuation of monitoring, or cholecystectomy, is necessary. Moderate strength recommendation, moderate-quality evidence. If during follow-up the gallbladder polypoid lesion disappears, then monitoring can be discontinued. Strong recommendation, moderate-quality evidence.
Source and scope These guidelines are an update of the 2017 recommendations developed between 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). A targeted literature search was performed to discover recent evidence concerning the management and follow-up of gallbladder polyps. The changes within these updated guidelines were formulated after consideration of the latest evidence by a group of international experts. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Key Point • These recommendations update the 2017 European guidelines regarding the management and follow-up of gallbladder polyps.

Abstract
Adenomyomatosis of the gallbladder is an acquired condition of the gallbladder with epithelial, mucosal, and muscular hypertrophy. The result is usually gallbladder wall thickening with associated diverticula known as Rokitansky-Aschoff's sinuses. These mucosal invaginations of the gallbladder wall may extend beyond the muscular layer. The condition is typically asymptomatic and is predominantly diagnosed in adults between 50 and 60 years of age, usually with concomitant cholelithiasis, motility disorders, or chronic inflammation. Few cases within the literature have been described in the pediatric population and even fewer within this subset have been diagnosed in infants. We describe a case of a 3-month-old male with failure to thrive, persistent nonbilious, nonbloody emesis, and elevated transaminases with ultrasound evidence of gallbladder adenomyomatosis. The patient was managed with outpatient laboratory monitoring and follow-up imaging.

Abstract
INTRODUCTION Gallbladder adenomyomatosis is a benign acquired gallbladder disease. It can mimic cancer on radiological findings, leading to a diagnostic dilemma. The management and prognosis of these two gallbladder anomalies are entirely different. Therefore, it is essential to recognize the pathognomonic features of gallbladder adenomyomatosis is in order to accurately diagnose this pathology. This paper presents two encountered cases of gallbladder adenomyomatosis is, their diagnostic modalities as well as the algorithmic approach of their management. These two-case reports have been reported in line with the SCARE Criteria 2020 [1]. PRESENTATION OF CASE Patient-1 was symptomatic. He was explored by an abdominal ultrasound picturing gallbladder wall thickening while the biopsy showed pleomorphic proliferation of inflammatory cells. An examination of the liver with MRI was indicated, showing diffuse parietal thickening with multiple cystic pockets. He underwent laparoscopic cholecystectomy with simple operative follow-up. Patient 2 was asymptomatic, a staging CT scan of acute pancreatitis revealed focal mural thinking of the gallbladder wall. A liver MRI showed an intramural cystic formation in the vesicular fundus. Given the inconclusive imaging results, laparoscopic cholecystectomy was performed. Histological examination confirmed the diagnosis of GA. DISCUSSION Adenomyomatosis is usually asymptomatic. Imaging can confirm the diagnosis of gallbladder adenomyomatosis without the need for invasive procedures such as vesicular biopsy. Histologic examination can also confirm the diagnosis when cholecystectomy is done. High resolution ultra-sound is the most efficient radiological examination. Laparoscopic cholecystectomy is the gold standard for symptomatic GA or radiological suspicion of a gallbladder cancer. CONCLUSION The practitioner should always consider gallbladder carcinoma before confirming the GA, as they share the same features but with a far worse prognosis. The likelihood of malignancy depends on radiological characteristics. In the case of inconclusive findings, cholecystectomy is justified.

Abstract
OBJECTIVES The objective of this study was to compare the difference of clinical biochemical statistics in different types of gallbladder adenomyomatosis (GA). To investigate the different effects of patients between the 3 different types of GA. MATERIALS AND METHODS Retrospective analysis of the clinical data of the adenomyomatosis patients that come from our hospital between 2010 to 2018. According to the preoperative image (all cases are performed as elective surgery), it could be divided into 3 groups: group A: fundal (localized) type; group B: segmental type; group C: diffuse type. The number of each group is 136, 27, 17. We analyze the biochemical statistics (total bilirubin, direct bilirubin, serum bile acid, alanine aminotransferase, aspartate aminotransferase, cholinesterase, etc.) of the 3 groups to explore the difference in operative mode, operative time and prognosis between these 3 groups. RESULTS (1) In the liver function statistics, aspartate aminotransferase has the statistical significance (F=4.974, P=0.012); (2) And the diffuse adenomyomatosis might have a higher bile acid (F=6.048, P=0.005); (3) The segmental and diffuse adenomyomatosis is easier to be combined with stones (F=19.226, P<0.001); (4) The fundal adenomyomatosis seems to have a better prognosis: fewer hospital stay (F=4.519, P=0.018), fewer drainage time (F=6.575, P=0.004) and fewer complications (χ=29.429, P<0.001). CONCLUSIONS GA is a disease characterized by epithelial proliferation and hypertrophy of the muscles of the gallbladder wall with an outpouching of the mucosa into or through the thickened muscular layer and cannot be regarded as a precancerous lesion based on available evidence. As for asymptomatic GA, conservative treatment is recommended with ultrasound examinations twice a year. The fundal type GA can be treated by partial laparoscopic cholecystectomy. The segmental and diffuse-type should undergo a total laparoscopic cholecystectomy.

Abstract
Gallbladder adenomyomatosis (GA) is a benign alteration of the gallbladder wall. There are three types involved: segmental, fundal, and diffuse pattern; the last type is very rare. Ultrasound is the imaging method of choice for diagnosing that shows Rokitansky-Aschoff sinuses with cholesterol deposition creating comet-tail artifacts. Asymptomatic GA does not require surgery in case there are no malignant lesions defined by imaging diagnosis. We present the rare case of a 51-year-old man who was admitted to hospital due to abdominal pain concomitant with inflammatory syndrome. Imaging and histological findings were appropriate to diagnose diffuse GA and complication of cholecystitis.

Abstract
Adenomyomatosis of the gallbladder is defined as hypertrophy of the gallbladder mucosal epithelium that invaginates into a thickened muscularis propria, leading to the formation of intramural diverticula. It is typically considered a benign condition most commonly affecting adults and, rarely, children. In this case report, we present a case of gallbladder adenomyomatosis in a 3-month-old infant. The diagnosis was made incidentally on ultrasound examination of the abdomen, in an otherwise asymptomatic child with no laboratory test abnormalities and no underlying disease. The purpose of this case report is to make infantile adenomyomatosis and its implications known to clinicians, as the literature on this topic is limited. To the best of our knowledge, this is the youngest reported case of adenomyomatosis in the pediatric population.

Abstract
BACKGROUND Preoperative differentiation between neoplastic and nonneoplastic gallbladder polyps, and the subsequent indication for cholecystectomy remains a clinical dilemma. The current 1 cm size threshold for neoplasia is unspecific. The aim of this study was to improve diagnostic work-up for gallbladder polyps using sonographic and MRI characteristics of neoplastic and nonneoplastic polyps. METHODS A prospective, exploratory study including patients undergoing cholecystectomy for gallbladder polyp(s) was conducted. Patients underwent targeted transabdominal ultrasound (TAUS) and MRI. Outcomes were sensitivity and specificity for polyp diagnosis, and the radiological characteristics of neoplastic and nonneoplastic polyp types. Histopathology after cholecystectomy was used as reference standard. RESULTS Histopathology demonstrated gallbladder polyps in 20/27 patients (74%): 14 cholesterol polyps, three adenomyomatosis, two adenomas and one gastric heterotopia. Sensitivity of polyp identification were 72% (routine TAUS) and 86% (targeted TAUS and MRI). Both adenomas were identified as neoplastic on targeted TAUS and MRI. Sonographic presentation as multiple, pedunculated polyps, either heterogeneous or with hyperechoic foci, or as single polyps containing cysts were limited to nonneoplastic polyps. On MRI hyperintense polyps on T1-weighted image were cholesterol polyps. An adenoma with high-grade dysplasia showed foci of decreased ADC values. We propose a checklist for polyp evaluation by targeted TAUS and a flowchart for radiological work-up of gallbladder polyps. CONCLUSIONS The presented checklist and flowchart could aid diagnostic work-up for gallbladder polyps compared to current routine ultrasound, by elimination of nonneoplastic polyps and ultimately improve treatment decision for patients with gallbladder polyps.

Abstract
Adenomyomatous hyperplasia (AH) is a tumor-like inflammatory hyperplastic lesion. In the biliary system, AH commonly arises in the gallbladder, but AH of the extrahepatic bile duct is extremely rare. AH usually develops and is found with symptoms related to biliary stenosis or obstruction, but there are few disease-specific manifestations. It is difficult to make a definitive diagnosis by imaging or cytopathological examination; thus, surgical resections were performed in all past reported cases. The pathophysiological etiology of AH is unknown, but it is considered to be associated with chronic inflammation. According to the epidemiological findings of cases reported to date, the possibility of malignant transformation is considered to be negative. However, the symptoms and imaging findings of AH are difficult to distinguish from those of early-stage bile duct carcinoma. In the current review, we discuss the epidemiology, pathophysiology, diagnosis, and management of AH of the bile duct.

Abstract
Bicameral gallbladder, also known as segmental adenomyomatosis, is not a rare benign condition with the lumen divided into 2 interconnected chambers. Here we present 2 interesting cases of the bicameral gallbladder, which shows unremarkable findings on hepatobiliary scintigraphy at first appearance. However, the CT scan revealed that the fundal chamber was not visualized on the scintigraphy unlike the ductal chamber. These cases suggest that the findings of the bicameral gallbladder on hepatobiliary scintigraphy can lead to misdiagnosis without carefully correlating with anatomic imaging findings.

Abstract
Gallbladder carcinoma is the most common cancer of the biliary system. It is challenging to diagnose because patients are often asymptomatic or present with nonspecific symptoms that mimic common benign diseases. Surgical excision is the only curative therapy and is best accomplished at early non-locally advanced stages. Unfortunately, gallbladder cancer often manifests at late locally advanced stages, precluding cure. Early tumors are often incidentally detected at imaging or at cholecystectomy performed for another indication. Typical imaging features of localized disease include asymmetric gallbladder wall thickening, polyps larger than 1.0 cm, and a solid mass replacing the gallbladder lumen. Advanced tumors are often infiltrative and can be confusing at CT and MRI owing to their large size. Determination of the origin of the lesion is paramount to narrow the differential diagnosis but is often challenging. It is important to identify gallbladder cancer and distinguish it from other benign and malignant hepatobiliary processes. Since surgical resection is the only curative treatment option, radiologist understanding and interpretation of pathways of nodal and infiltrative tumor spread can direct surgery or preclude patients who may not benefit from surgery. While both CT and MRI are effective, MRI provides superior soft-tissue characterization of the gallbladder and biliary tree and is a useful imaging tool for diagnosis, staging, and evaluation of treatment response. ©RSNA, 2020.

BACKGROUND AND AIMS There is no clear guideline nor protocol for macroscopic examination of the gallbladder, leaving surgeons extemporaneous in regard of gallbladder examination in selective histopathologic policy. The purpose of this article is to describe a surgical approach for adequate macroscopic inspection of the gallbladder. MATERIALS AND METHODS The described practical method was developed in collaboration between surgeons and pathologists. This method was introduced in 2011 and implemented in 2012. We retrospectively reviewed the number of cholecystectomies and number of histopathologic examinations between 2006 and 2017, using our own patient database. We used the Netherlands Cancer Registry (NCR) to examine the incidence of gallbladder cancer patients before and after implementation of the selective policy in our hospital. In addition to the method, we depict several frequent macroscopic abnormalities in order to provide some examples for surgical colleagues. RESULTS Since implementation of the selective policy, 2271 surgical macroscopic gallbladder examinations were performed. As a result, we observed a significant decrease from 83% in 2012 to 38% in 2017, in histopathologic examination of the gallbladder following cholecystectomy. We observed a stable trend of gallbladder carcinoma in the same period (0.17%, n = 4 during 2006-2011 and 0.26%, n = 6 during 2012-2017). CONCLUSION A simple, valid and easy method is described for future macroscopic analysis by the surgeon following a cholecystectomy.

Abstract
Gallbladder adenomyomatosis (GA) is increasingly encountered in clinical practice due to increasing use of imagings especially ultrasound (US). Clinicians need to know what is the implication of this condition and its proper management. GA is a degenerative and proliferative disease characterized by excessive epithelial proliferation associated with hypertrophy of muscularis propria. This leads to outpouchings of mucosa into or beyond the muscle layer forming intramural diverticula recognized as Rokitansky-Aschoff sinuses (RAS). Three types of GA are recognised: fundal, segmental and diffuse type. In fundal GA, there is focal thickening involving the GB fundus. In segmental GA, there is circumferential overgrowth of the GB wall that leads to formation of compartments. In diffuse GA, there is disseminated thickening and irregularity of the mucosa and muscularis. The pathogenesis of GA is unknown. It commonly occurs in middle age with equal sex distribution. Diagnosis of GA is by imagings showing thickened gallbladder wall containing cysts. Characteristic features are “comet-tail” artefacts and “twinkling” artefacts on US, “pearl-necklace sign” on magnetic resonance imaging (MRI) and “rosary sign” on computed tomography (CT). Cholecystectomy should be offered for symptomatic GA of any type. For asymptomatic GA, cholecystectomy may be considered for segmental type for its increased risk of malignancy and for diffuse type for its difficult visualization of any coexisting malignancy. Asymptomatic fundal GA can be safely observed with US. How frequent and how long should a fundal GA be monitored with US remains unknown. In case of diagnostic doubt, cholecystectomy should always be offered to avoid overlooked malignancy.

Abstract
Gallbladder (GB) polyp is a mucosal projection into the GB lumen. With increasing health awareness, GB polyps are frequently found using ultrasonography during health screening. The prevalence of GB polyps ranges between 1.3% and 9.5%. Most patients are asymptomatic and have benign characteristics. Of the nonneoplastic polyps, cholesterol polyps are most common, accounting for 60%-70% of lesions. However, a few polyps have malignant potential. Currently, the guidelines recommend laparoscopic cholecystectomy for polyps larger than 1 cm in diameter due to their malignan potential. The treatment algorithm can be influenced by the size, shape, and numbers of polyps, old age (>50 years), the presence of primary sclerosing cholangitis, and gallstones. This review summarizes the commonly recognized concepts on GB polyps from diagnosis to an algorithm of treatment.

Abstract
BACKGROUND Gallbladder polyps are relatively common. Although most gallbladder polyps are benign, some are malignant. Current guidelines state that malignancy should be suspected for polyps ≥ 10 mm in diameter. We clarified the cancer detection rates in accordance with the size distribution of gallbladder polyps, and evaluated the effectiveness of the reported risk factors in predicting malignancy. METHODS In this retrospective case-control study, our institutional database was searched to identify patients who underwent laparoscopic cholecystectomy for benign or malignant gallbladder polyps at Sada Hospital, Japan. The chi-squared test was used to analyze the risk factors for malignancy. RESULTS There were 227 protruding gallbladder lesions. The 206 benign polyps had a diameter of 2-21 mm, while the 21 malignant polyps were 7-60 mm. The cancer detection rates were 16.4% for lesions ≥ 10 mm, 55.9% for lesions ≥ 15 mm, and 94.1% for lesions ≥ 20 mm. Of the benign lesions, cholesterol polyps were the most frequent (50-100%) in all size ranges, even in large lesions (≥ 15 mm). The sessile lesion morphology was significantly more frequent in malignant (60%) than benign lesions (3.4%, p < 0.00001). Multiple polyps were frequently diagnosed not only as cholesterol polyps (81.1%), but also as adenomas (60%); adenomas were found as a single adenoma within other types of polyps. There were two cases of malignant small gallbladder polyps (< 10 mm); these lesions met the surgical indications of a size increase during observation or a sessile morphology. CONCLUSIONS The cancer detection rate increased significantly with an increase in the lesion size. Risk factors such as a sessile polyp morphology or an increase in lesion size were effective in predicting malignancy for small gallbladder polyps. It might be difficult to accurately predict the pathologic diagnoses of gallbladder polyps preoperatively, as cholesterol polyps were most frequent, even in the large size range.

Abstract
Background Unexpected gallbladder cancer (UGBC) is sometimes found in the resected gallbladder of patients during or after surgery. Some reports have indicated UGBC identification rates for all gallbladder surgeries, but scarce data are available for the UGBC identification rates for specific gallbladder diseases. The present study was performed to clarify UGBC rates and the factors suspicious for UGBC categorized according to preoperative diagnoses, in patients undergoing laparoscopic cholecystectomy (LSC). Methods We recorded data for all LSC surgeries performed in the Department of Surgery, Sada Hospital, Japan since 1991, and analyzed the 28-year data. We used the chi-square test and Kaplan–Meier analysis for this retrospective case–control study. Results The UGBC identification rate was 0.69% (63/9186 patients). The UGBC identification rates categorized according to the preoperative diagnoses were 1.3% (13/969) for acute cholecystitis, 2.4% (16/655) for benign tumor, 2.0% (28/1383) for chronic cholecystitis or cholecystitis, and 0.054% (3/5585) for cholecystolithiasis. The percentage of older patients (≥ 60 years) was significantly higher in UGBCs compared with cases finally diagnosed as benign in each group categorized according to the preoperative diagnoses (p≤0.0014), except for cholecystolithiasis. In cases pre-diagnosed as benign tumor, UGBCs were associated with higher rates of thickened gallbladder wall compared with benign tumor (69.2% vs. 27.9%, respectively; p = 0.0011). UGBCs pre-diagnosed as acute cholecystitis had higher T2–T4 rates (100% vs. 64.3%, respectively; p<0.05) and lower survival rates (p = 0.0149) than UGBCs pre-diagnosed with chronic cholecystitis. Conclusions UGBC identification rates depend on the preoperative diagnosis and range from 0.054% to 2.4%. Older age (≥ 60 years) could be related to UGBC, and a pre-diagnosis of acute cholecystitis might indicate more advanced cancer compared with a pre-diagnosis of chronic cholecystitis.

Abstract
Adenomyosis and endometriosis are common gynecological disorders, but their pathophysiology is still under debate. The aim of this review is to discuss whether adenomyosis and endometriosis represent two different entities or different phenotypes of a single disease. We searched PubMed electronic databases published between January 2000 and April 2020. Endometriosis is classified into three phenotypes; superficial peritoneal disease (SUP), ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE) lesions. Adenomyosis presents several different subtypes, including intrinsic adenomyosis, extrinsic adenomyosis, adenomyosis externa and focal adenomyosis located in the outer myometrium (FAOM). Human uterus is embryologically composed of archimetra, originating from the Müllerian duct, and neometra, arising from the non-Müllerian duct, and adenomyosis and endometriosis are diseases of archimetra. The outer myometrial layer of the uterus is composed of highly differentiated smooth muscle cells (SMCs), while the inner myometrial cells are immature. Inappropriate uterine contractions can cause retrograde menstruation and chronic inflammation in the pelvic cavity, then influencing the development of pelvic endometriosis. Furthermore, hyperperistalsis results in physiological and pathological changes to the endometrial-myometrial junctional barrier, allowing invagination of the normal endometrial tissue into the inner myometrial layer. This can trigger the development of intrinsic adenomyosis. There are insufficient data available to draw conclusions, but extrinsic adenomyosis may result from pelvic endometriosis and FAOM from rectal and bladder DIE/adenomyosis externa. In conclusions, this paper contributes to the debate in the possibility that adenomyosis and endometriosis represent different phenotypes of a single disease.

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
BACKGROUND/PURPOSE The aim of the present study was to investigate the relationship between hepatobiliary scintigraphy findings and histopathological results in patients with recurrent biliary colic. METHODS We retrospectively enrolled 107 patients who underwent hepatobiliary scintigraphy for recurrent biliary colic and subsequent cholecystectomy. According to the hepatobiliary scintigraphy findings, patients were categorized into a nonvisualization of gallbladder activity (nonvisualized GB) group, low gallbladder ejection fraction (GBEF) group, and normal GBEF group. Differences in histopathologic factors between the three groups were evaluated and multivariate logistic regression analyses were performed to identify histopathological predictors for hepatobiliary scintigraphy findings. RESULTS The nonvisualized group had a higher frequency of patients with empyema and severe infiltration by neutrophils, lymphoplasma cells, and eosinophils. The low GBEF group had a higher muscle-to-total wall thickness ratio and muscle-to-fibrosis thickness ratio of the gallbladder wall than those in the normal GBEF group. On multivariate logistic regression analyses, severe degrees of lymphoplasma cell infiltration and eosinophil infiltration were independent predictors for nonvisualization of gallbladder activity, and a higher muscle-to-fibrosis thickness ratio was an independent predictor for low GBEF. CONCLUSIONS In patients with recurrent biliary colic, nonvisualization of gallbladder activity on hepatobiliary scintigraphy was related to the degree of inflammation in the gallbladder, while low GBEF was related to muscular hypertrophy of the gallbladder.

Abstract
Although transabdominal imaging of the gallbladder has become a gold standard, new light should be shed on some aspects, which will prove useful in everyday practice. Therefore, based on our own experience and the available literature, we would like to draw attention to those elements of gallbladder ultrasound imaging which may increase its diagnostic efficacy. The paper draws attention to the difficulty in assessing certain anatomical structures, such as the inferior wall, the bottom and the region of the neck of the gallbladder, and offers ways to improve their imaging. We also emphasized the negative effects of duodenal and transverse colon (along with their contents) adhesion to the bottom of the gallbladder on the correct diagnosis. Due to the importance of size in the management strategy for detected gallbladder polyps, we suggest their measurement on an image enlarged with the zoom function. This technique also allows for an accurate assessment of the shape and echostructure of these lesions. An enlarged image of a polyp makes it possible to trace its behavior in time. We also remind that the hepatic wall of the gallbladder is the only site allowing for a reliable wall thickness measurement. We also pointed to the importance of changing patient’s position when assessing the mobility and the nature of lesions. Altering patient’s position during examination may help detect anomalies in the form of a floating gallbladder, which may promote its torsion. Finally, pathologies whose diagnosis may be facilitated by color-coded blood flow imaging are also presented. The issues discussed in this paper are only a fraction of problems faced by an ultrasound operator in the field of gallbladder diagnostic imaging. However, the proposed ultrasound approaches should help solve some of these problems in everyday practice.

Abstract
PURPOSE This study aimed to assess radiological findings of adenomyomatosis advancing to chronic inflammation to differentiate between adenomyomatosis with and without chronic inflammation. MATERIALS AND METHODS We retrospectively identified 79 patients with pathologically proven adenomyomatosis without (n = 10) or with chronic inflammation (n = 69), who underwent computed tomography (CT) and magnetic resonance imaging (MRI) followed by surgery. MRI analysis included evaluation of GB wall-thickening type, presence and location of intramural cysts, and presence of stones. CT analysis included GB wall-thickening type only. Multivariate logistic regression analysis was used to identify the image-based findings of adenomyomatosis associated with chronic inflammation. RESULTS On univariate analysis, MRI-based GB wall-thickening type and presence of stones, and CT-based GB wall-thickening type were significantly different between adenomyomatosis with and without chronic inflammation. On multivariate analysis, only the absence of stones was identified as a significant predictor of adenomyomatosis without chronic inflammation (odds ratio 5.58; 95% confidence interval 1.20-26.01; p = 0.029). There was no significant difference in other MRI- and CT-based findings between adenomyomatosis with and without chronic inflammation. CONCLUSION In patients with adenomyomatosis, the presence of stones was independently associated with chronic inflammation.

Abstract
OBJECTIVE Adenomyoma, a reactive and hamartomatous lesion of the gallbladder, is included in the differential diagnosis of several benign and malignant lesions. Macroscopic sampling is very important in the determination of these lesions. The agreed macroscopy protocol in recent years has been prepared by the Hepatopancreatobiliary Pathology Working Group. We aimed to evaluate the clinicopathologic properties of adenomyoma cases in the gallbladder and the contribution of new macroscopy techniques to the diagnosis of adenomyoma in the pre-protocol and post-protocol parts of a one-year period. MATERIAL AND METHOD Two institutes were included in the study. Adenomyoma cases diagnosed in the pre-protocol and post-protocol periods of one year duration were included in the study. Slides and demographic properties of the cases were reexamined. RESULTS While adenomyoma was present in 22 of 1879 gallbladder before the protocol, it was observed in 32 of 1781 gallbladders in the post-protocol period. 17 of the cases were male and 37 were female. The mean age of the cases was 51.8. 52% of the lesions were located in the fundus. A gallstone was observed in 37 cases, and cholesterolosis in 14 cases. In the comparison of the two periods, the number of cases was lower in the post-protocol period but a 0.6% increase in the diagnosis of adenomyoma was found. CONCLUSION Adenomyoma is one of the lesions of the gallbladder that should be recognized but can be easily overlooked macroscopically. When we conducted the sampling according to the last protocol, the increase in the diagnosis of adenomyoma showed that adequate and accurate sampling was very useful for the detection of adenomyoma in the gallbladder.

Combined Fundal and Segmental Adenomyomatosis of the Gallbladder in a Child: A Rare Case Report. Case Rep Pediatr 2019; 2019:2659089. [PMID: 31871811 PMCID: PMC6907037 DOI: 10.1155/2019/2659089] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 10/29/2019] [Indexed: 11/17/2022] Open
Abstract
Adenomyomatosis of the gallbladder (AMG) is characterized by mucosal hyperplasia leading to invagination through the thickened muscle layer, which is relatively common in adults, but is rare in childhood. We report a 12-year-old boy with adenomyomatosis of the gallbladder combined segmental and fundal type. This combined type is rare in adults and is first reported here in childhood. Although initial imaging with computed tomography (CT) suggested the presence of a circular solid mass-like lesion because of its rare morphology, repeated ultrasonography (US) was useful for leading to a correct diagnosis.

Abstract
The exact pathogenesis of gallbladder adenomyomatosis is still lacking and some controversies over its diagnosis and treatment exist. Originally recognized as a precancerous lesion, adenomyomatosis is currently recognized by recent studies as a benign alteration of the gallbladder that is often associated with cholecystitis and cholecystolithiasis. Gallbladder carcinoma is an extremely malignant disease with a 5-year survival rate of less than 5%. Therefore, it is important to diagnose, differentiate, and confirm the relationship between adenomyomatosis and early-stage gallbladder carcinoma. However, the early clinical symptoms of adenomyomatosis are extremely similar to those of gallbladder stones and cholecystitis, increasing the difficulty to identify and treat this disease. This article summarizes the research progress on gallbladder adenomyomatosis, aiming to improve the understanding of the pathogenesis of adenomyomatosis and further provide insight for its clinical diagnosis and treatment.
