Endoscopic Ultrasonography-Guided Gallbladder Drainage.

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has emerged as a popular alternative to percutaneous cholecystostomy and endoscopic transpapillary gallbladder drainage for patients suffering from acute calculous cholecystitis who are at high risk for surgery. Multiple cohorts, meta-analyses, and a randomized controlled trial have shown that EUS-GBD has lower rates of recurrent cholecystitis and unplanned reinterventions, while achieving similar technical and clinical success rates than transpapillary cystic duct stenting. The essential steps, precautions in performing EUS-GBD and long-term management will be discussed in this article.

Determining the patency of biliary tracts in dogs with gallbladder mucocele using near-infrared cholangiography with indocyanine green.

Cholecystectomy is indicated for gallbladder mucoceles (GBM). Evaluating the patency of the biliary duct and precise biliary tree visualization is crucial for reducing the risk of compromised bile flow after surgery. Therefore, intraoperative cholangiography (IOC) is recommended during cholecystectomy to prevent biliary tract injury. Although indocyanine green (ICG) cholangiography has been extensively reported in human medicine, only one study has been conducted in veterinary medicine. Therefore, this study aimed to demonstrate the use of ICG for IOC to identify fluorescent biliary tract images and determine the patency of the common bile duct during cholecystectomy in dogs. This study comprised 27 dogs, consisting of 17 with gallbladder mucoceles (GBM) and 10 controls, specifically including dogs that had undergone elective cholecystectomy for GBM. ICG injection (0.25 mg/kg) was administered intravenously at least 45 minutes before surgery. During the operation, fluorescent images from cholangiography were displayed on the monitor and obtained in black-and-white mode for the comparison of fluorescence intensity (FI). The FI values of the gallbladders (GBs) and common bile duct (CBD) were measured using FI analyzing software (MGViewer V1.1.1, MetapleBio Inc.). The results demonstrated successful CBD patency identification in all cases. Mobile GBM showed partial gallbladder visibility, whereas immobile GBM showed limited visibility. Additionally, insights into the adequate visualization of the remaining extrahepatic biliary tree anatomy were provided, extending beyond the assessment of CBD patency and gallbladder intensity. Our study demonstrates the potential of fluorescent IOC using intravenous injection of ICG for assessing the patency of the cystic duct and common bile duct during cholecystectomy in patients with GBM, eliminating the need for surgical catheterization and flushing of the biliary ducts. Further research is warranted to investigate and validate the broader applicability of ICG cholangiography in veterinary medicine.

Contributions of endoscopic ultrasonography-guided tissue acquisition (EUS-TA) to the diagnostics of biliary stricture and gallbladder lesions.

Endoscopic ultrasonography (EUS) provides high spatial resolution and more detailed images than other diagnostic modalities. Furthermore, EUS-guided tissue acquisition (EUS-TA), such as EUS-guided fine needle aspiration or biopsy (EUS-FNA/FNB), is an indispensable tool in pancreaticobiliary disease diagnostics, supporting a conclusive pathological diagnosis. In this review, we evaluate the current status and the usefulness of EUS-TA for the diagnostics of the following biliary tract diseases: (A) biliary stricture diagnostics, (B) biliary tract cancer (BTC) itself, and (C) staging of advanced BTC. Previous reports have shown that EUS-FNA for biliary lesions is a safe procedure that is useful in differentiating biliary cancer from benign lesions and in the staging of BTC. On the other hand, the diagnostic performance of EUS-TA for bile duct lesions is reported to be similar to that of transpapillary biopsy. Overall, EUS-TA for biliary lesions may be a safe and effective method, but it should be performed with an understanding of the risk of serious adverse events such as bile leakage and peritoneal dissemination of cancer. It is recommended for distal biliary stricture lesions for which endoscopic retrograde cholangiopancreatography cannot confirm the diagnosis or gallbladder lesions if they do not require the needle to pass through the biliary lumen.

Uncommon Presentation of Xanthogranulomatous Cholecystitis in a True Gallbladder Diverticulum: A Case Report and Literature Review.

BACKGROUND The gallbladder develops from the hepatic diverticulum during the fourth week of gestation, which also give rise to the liver, extrahepatic biliary ducts, and ventral part of the pancreas. Infrequently, the gallbladder has malformation or disruption in embryogenesis, leading to congenital anomalies. There are various congenital anomalies that can arise in the gallbladder. True or congenital diverticulum of the gallbladder is a rare entity that accounts for only 0.06% of gallbladder congenital anomalies and 0.0008% of cholecystectomies at the Mayo Clinic. CASE REPORT Herein, we report a rare case of a 38-year-old woman who presented to Jubail General Hospital's surgery clinic with right upper-quadrant (RUQ) pain associated with vomiting after meals for 1 month. Laparoscopic cholecystectomy was done and gallbladder tissue was sent to histopathology. Gross examination revealed an outpouching mucosa within the wall that was proven to consist of muscularis and serosa layers under light microscope. Interestingly, xanthogranulomatous inflammation was confined to the diverticulum, unlike the chronic inflammation involving the remaining gallbladder. Based on the above findings, the diagnosis of congenital diverticulum with xanthogranulomatous cholecystitis was made. CONCLUSIONS Gallbladders associated with a true diverticulum are uncommonly found to be buried in the liver, leading to surgical difficulties during cholecystectomy. Therefore, background knowledge of occasional anomalies plays a crucial role in guiding the surgeon to choose the optimal method of management. We also discuss the associated complications that accompany these anomalies, such as non-specific prolonged ailments, acalculous cholecystitis, cholecystitis and cholelithiasis, recurrent cholangitis, and carcinoma of the gallbladder.

Discrimination between benign and malignant gallbladder lesions on enhanced CT imaging using radiomics.

BACKGROUND: Gallbladder cancer is a rare but aggressive malignancy that is often diagnosed at an advanced stage and is associated with poor outcomes. PURPOSE: To develop a radiomics model to discriminate between benign and malignant gallbladder lesions using enhanced computed tomography (CT) imaging. MATERIAL AND METHODS: All patients had a preoperative contrast-enhanced CT scan, which was independently analyzed by two radiologists. Regions of interest were manually delineated on portal venous phase images, and radiomics features were extracted. Feature selection was performed using mRMR and LASSO methods. The patients were randomly divided into training and test groups at a ratio of 7:3. Clinical and radiomics parameters were identified in the training group, three models were constructed, and the models' prediction accuracy and ability were evaluated using AUC and calibration curves. RESULTS: In the training group, the AUCs of the clinical model and radiomics model were 0.914 and 0.968, and that of the nomogram model was 0.980, respectively. There were statistically significant differences in diagnostic accuracy between nomograms and radiomics features (P <0.05). There was no significant difference in diagnostic accuracy between the nomograms and clinical features (P >0.05) or between the clinical features and radiomics features (P >0.05). In the testing group, the AUC of the clinical model and radiomics model were 0.904 and 0.941, and that of the nomogram model was 0.948, respectively. There was no significant difference in diagnostic accuracy between the three groups (P >0.05). CONCLUSION: It was suggested that radiomics analysis using enhanced CT imaging can effectively discriminate between benign and malignant gallbladder lesions.

Endoscopic Gallbladder Drainage: A Comprehensive Review on Indications, Techniques, and Future Perspectives.

In recent years, therapeutic endoscopy has become a fundamental tool in the management of gallbladder diseases in light of its minimal invasiveness, high clinical efficacy, and good safety profile. Both endoscopic transpapillary gallbladder drainage (TGBD) and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD) provide effective internal drainage in patients with acute cholecystitis unfit for cholecystectomy, avoiding the drawbacks of external percutaneous gallbladder drainage (PGBD). The availability of dedicated lumen-apposing metal stents (LAMS) for EUS-guided transluminal interventions contributed to the expansion of endoscopic therapies for acute cholecystitis, making endoscopic gallbladder drainage easier, faster, and hence more widely available. Moreover, EUS-GBD with LAMS opened the possibility of several cholecystoscopy-guided interventions, such as gallstone lithotripsy and clearance. Finally, EUS-GBD has also been proposed as a rescue drainage modality in malignant biliary obstruction after failure of standard techniques, with encouraging results. In this review, we will describe the TBGD and EUS-GBD techniques, and we will discuss the available data on clinical efficacy in different settings in comparison with PGBD. Finally, we will comment on the future perspectives of EUS-GBD, discussing the areas of uncertainty in which new data are more strongly awaited.

Pathologic significance of peribiliary capillary plexus in gallbladder neoplasm.

AIMS: Significance of peribiliary capillary plexus (PCP) in gallbladder neoplasms remains unclear. Aims are to characterize high-grade biliary intraepithelial neoplasm (BilIN), pyloric gland adenoma (PGA), and intracholecystic papillary neoplasm (ICPN), precursors of gallbladder carcinoma, and to differentiate invasive carcinoma from pseudo-invasive lesions in gallbladder walls, referring to PCP. MATERIALS AND METHODS: High-grade BilIN (38 cases), PGA (5 cases), and ICPN (25 cases) were examined using capillary immunostaining. Non-neoplastic gallbladders were used as controls. RESULTS: In non-neoplastic gallbladders, a single layer of regularly dotted capillaries (PCP) was located beneath lining epithelia and around non-neoplastic glands (NNGs), including Rokitansky-Aschoff sinus (RAS), presenting a two-layer of lining epithelia and PCP. Intra-luminal components of all cases of high-grade BilIN and PGA and one-third of ICPNs presented a two-layer pattern. In the remaining ICPNs, capillaries were irregular and sparse in intraluminal neoplastic components presenting irregular and complicated lesions. Neoplastic glands in gallbladder walls of high-grade BilIN and ICPN were classifiable into 2 types: glands that were underlain by densely dotted capillaries and those that were not, with the latter suggestive of invasive carcinoma, while the former suggestive of non-invasive neoplasms involving NNGs intraepithelially and/or showing an expanding growth into gallbladder wall (pseudo-invasion). CONCLUSION: A two-layer pattern of lining epithelia and underlining capillaries were preserved in all cases of high-grade BilIN and PGA and one-third of ICPN cases. Presence or absence of dotted capillaries around neoplastic glands may be able to be added as a new pathologic feature to differentiate invasive carcinomas from pseudo-invasion in gallbladder wall.

Hif-1α expression targets the TMA/Fmo3/TMAO axis to participate in gallbladder cholesterol stone formation in individuals living in plateau regions.

The incidence of gallbladder cholesterol stones (GCS) increases rapidly among people living in high-altitude hypoxic environments compared to those in normoxic areas. Upregulation of hepatic hypoxia inducible factor 1α (Hif-1α) plays a key role in the formation of GCS. High plasma trimethylamine-N-oxide (TMAO) levels are positively correlated with the occurrence of GCS. We hypothesized that HIF-1α may upregulate TMAO levels by promoting the transcription of flavin-containing monooxygenase 3 (Fmo3), which eventually leads to GCS formation. Our study shows that in women, high plasma total cholesterol and apolipoprotein B were positively correlated with cholecystolithiasis and hypoxia. Hif-1α binds to the Fmo3 promoter and promotes Fmo3 expression. Hypoxia and lithogenic diet induce the expression of Hif-1α, Fmo3, TMAO and cholesterol tube transporters in the livers of mice, disturb the proportion of bile and plasma components, and induce the formation of GCS. In cell experiments, silencing Hif-1α downregulates the expression of Fmo3, TMAO and cholesterol tube transporters. In a mouse model of hypoxic cholecystolithiasis, silencing Hif-1α downregulates the expression of related genes, restores the proportion of bile and plasma lipid components, and reduces the formation of GCS. Our study shows that Hif-1α binds to the promoter region of Fmo3 and promotes Fmo3 transcription. Thus, it mediates the transcriptional activation of the TMA/Fmo3/TMAO pathway, upregulates the expression of ATP-binding cassettes (Abc) g5 and g8, and participates in the regulation of the occurrence of GCS in the plateau region.

The value of CT radiomics combined with deep transfer learning in predicting the nature of gallbladder polypoid lesions.

BACKGROUND: Computed tomography (CT) radiomics combined with deep transfer learning was used to identify cholesterol and adenomatous gallbladder polyps that have not been well evaluated before surgery. PURPOSE: To investigate the potential of various machine learning models, incorporating radiomics and deep transfer learning, in predicting the nature of cholesterol and adenomatous gallbladder polyps. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and imaging data from 100 patients with cholesterol or adenomatous polyps confirmed by surgery and pathology at our hospital between September 2015 and February 2023. Preoperative contrast-enhanced CT radiomics combined with deep learning features were utilized, and t-tests and least absolute shrinkage and selection operator (LASSO) cross-validation were employed for feature selection. Subsequently, 11 machine learning algorithms were utilized to construct prediction models, and the area under the ROC curve (AUC), accuracy, and F1 measure were used to assess model performance, which was validated in a validation group. RESULTS: The Logistic algorithm demonstrated the most effective prediction in identifying polyp properties based on 10 radiomics combined with deep learning features, achieving the highest AUC (0.85 in the validation group, 95% confidence interval = 0.68-1.0). In addition, the accuracy (0.83 in the validation group) and F1 measure (0.76 in the validation group) also indicated strong performance. CONCLUSION: The machine learning radiomics combined with deep learning model based on enhanced CT proves valuable in predicting the characteristics of cholesterol and adenomatous gallbladder polyps. This approach provides a more reliable basis for preoperative diagnosis and treatment of these conditions.

The results suggest an association between metaplasia, dysplasia and gallbladder cancer in the study population. Additional research is recommended to define the possible causality between metaplasia, dysplasia, and gallbladder cancer in a more heterogeneous population.

Gallbladder carcinoid in a cat.

Carcinoids are rare tumors that originate from neuroendocrine system cells. There has apparently only been 1 report in the veterinary medical literature of a cat with a gallbladder carcinoid, with no long-term follow-up information available from that case. Furthermore, apparently only 9 dogs with gallbladder carcinoids have been reported, again with no long-term follow-up. This case report describes the clinical presentation, surgical appearance, histopathologic and immunohistochemical findings, postoperative adjuvant chemotherapy treatment, and long-term outcome of a domestic longhair cat with a gallbladder carcinoid. The diagnosis of a gallbladder carcinoid in the present case was based on histologic and immunohistochemical findings. Clinical signs of a gallbladder carcinoid are nonspecific and ultrasonographic findings may not be definitive; however, it should be considered as a potential differential diagnosis in cats with lesions of the gallbladder or in the region of the gallbladder. The prognosis is poor, with a potentially high metastatic rate. In the present case, metastasis occurred 7 mo postoperatively despite adjuvant therapy, and the survival time was only 10 mo from the time of diagnosis. Key clinical message: This case report describes the clinical presentation, surgical appearance, histopathologic and immunohistochemical findings, postoperative adjuvant treatment, and long-term outcome of a cat with a gallbladder carcinoid, which should be considered as a potential differential diagnosis in cats with lesions of the gallbladder or in the region of the gallbladder.

Carcinoïde de la vésicule biliaire chez un chat. Les carcinoïdes sont des tumeurs rares qui prennent leur origine des cellules du système neuroendocrinien. Dans la littérature médicale vétérinaire il n'y aurait qu'un seul cas rapporté d'un chat avec un carcinoïde de la vésicule biliaire, sans aucune information de suivi à long terme disponible pour ce chat. Également, il y aurait 9 cas rapportés de chiens avec des carcinoïdes de la vésicule biliaire, mais encore là aucun suivi à long terme. Le cas présenté ici décrit la présentation clinique, l'apparence chirurgicale, les trouvailles histopathologiques et immunohistochimiques, le traitement post-opératoire par chimiothérapie adjuvante, et le devenir à long terme d'un chat domestique à poil court avec un carcinoïde de la vésicule biliaire. Dans le cas présent, le diagnostic de carcinoïde de la vésicule biliaire était basé sur les trouvailles histologiques et immunohistochimiques. Les signes cliniques d'un carcinoïde de la vésicule biliaire sont non-spécifiques et les trouvailles échographiques pourraient ne pas être concluantes; toutefois, il devrait être considéré comme un diagnostic différentiel possible chez des chats avec des lésions à la vésicule biliaire ou dans la région de la vésicule biliaire. Le pronostic est mauvais, avec un risque élevé de métastases. Dans le cas présent, des métastases sont apparues 7 mo post-chirurgie malgré une chimiothérapie adjuvante, et le temps de survie a été de 10 mo à compter du moment du diagnostic.Message clinique clé:Ce rapport de cas décrit la présentation clinique, l'apparence chirurgicale, les trouvaille histologiques et immunohistochimiques, la thérapie adjuvante postopératoire, et le résultat à long-terme pour un chat avec un carcinoïde de la vésicule biliaire, qui devrait être considéré comme un diagnostic différentiel potentiel chez les chats avec des lésions à la vésicule biliaire ou dans la région de la vésicule biliaire.(Traduit par Dr Serge Messier).

Preoperative diagnostic criteria for scleroatrophic gallbladder: A systematic review protocol.

BACKGROUND: Although scleroatrophic gallbladder is a rare condition, it presents significant clinical challenges in diagnosis and management. More agreement is needed on this disorder's diagnostic criteria and optimal management approach. We will conduct a systematic review to summarise the scleroatrophic gallbladder's preoperative diagnostic criteria, including imaging modalities. METHODS: A systematic review will be undertaken using the PRISMA guidelines. The protocol has been registered in PROSPERO (CRD42024503701). We will search in Medline (via PubMed), Embase, SCOPUS, the Cochrane Library, and Web of Science to find original studies reporting about scleroatrophic gallbladder or synonymous. Two reviewers will independently screen the titles and abstracts following the eligibility criteria. We will include all types of studies that describe any diagnostic criteria or tools. After retrieving the full text of the selected studies, we will conduct a standardised data extraction. Finally, a narrative synthesis will be performed. The quality of the identified studies will be assessed using the Quality Assessment of Diagnostic Accuracy Studies- 2 tool. DISCUSSION: This systematic review will provide information on the preoperative diagnostic criteria of the scleroatrophic gallbladder and the value of imaging studies in its diagnosis. In addition, this work will aid doctors in the decision-making process for diagnosing scleroatrophic gallbladder and propose treatment approaches to this condition. SYSTEMATIC REVIEW REGISTRATION: The protocol has been registered in PROSPERO (CRD42024503701).

Analysis of the sonographic predictors of difficult laparoscopic cholecystectomy in symptomatic cholelithiasis.

BACKGROUND: Laparoscopic cholecystectomy (LC) is one of the most common laparoscopic procedures performed by young surgeons nowadays. Sometimes, LC could be challenging, especially for junior surgeons leading to serious complications. Therefore, this study aims to investigate the preoperative ultrasonographic features that could predict difficult LC. METHODS: In this prospective study, patients (n = 204) who underwent LC for symptomatic cholelithiasis from January 2020 to August 2022 were included. Preoperative parameters, including the ultrasonographic findings, were evaluated for their ability to predict difficult LC. RESULTS: The difficulty of LC was evaluated using two intraoperative scores. Among the ultrasonic parameters that were assessed preoperatively, thickened gallbladder (GB) wall, contracted GB, and impacted stone in the GB neck were associated with difficult LC. However, an impacted stone in the GB neck was the only independent predictor of difficult LC according to both difficulty scores in the multivariate analysis (odds ratio [OR] = 7.56, p = .001; OR = 8.42, p = .001). CONCLUSIONS: The impacted stone in the GB neck is an ultrasonographic sign of difficult LC. It should alert the surgeon for a more appropriate preoperative preparation, and the patient should be informed about the increased risk of complications, including conversion to open cholecystectomy.

The Efficacy of Chaihu-Guizhi-Ganjiang Decoction on Chronic Non-Atrophic Gastritis with Gallbladder Heat and Spleen Cold Syndrome and Its Metabolomic Analysis: An Observational Controlled Before-After Clinical Trial.

Purpose: The aim of this study was to verify the effectiveness and explore the mechanism of Chaihu-Guizhi-Ganjiang decoction (CGGD) in the treatment of chronic non-atrophic gastritis (CNAG) with gallbladder heat and spleen cold syndrome (GHSC) by metabolomics based on UHPLC-Q-TOF/MS. Patients and Methods: An observational controlled before-after study was conducted to verify the effectiveness of CGGD in the treatment of CNAG with GHSC from January to June 2023, enrolling 27 patients, who took CGGD for 28 days. 30 healthy volunteers were enrolled as the controls. The efficacy was evaluated by comparing the traditional Chinese medicine (TCM) syndrome and CNAG scores, and clinical parameters before and after treatment. The plasma levels of hormones related to gastrointestinal function were collected by ELISA. The mechanisms of CGGD in the treatment of CNAG with GHSC were explored using a metabolomic approach based on UHPLC-Q-TOF/MS. Results: Patients treated with CGGD experienced a statistically significant improvement in TCM syndrome and CNAG scores (p < 0.01). CGGD treatment evoked the concentration alteration of 15 biomarkers, which were enriched in the glycerophospholipid metabolism, and branched-chain amino acids biosynthesis pathways. Moreover, CGGD treatment attenuated the abnormalities of the gastrointestinal hormone levels and significantly increased the pepsinogen level. Conclusion: It was the first time that this clinical trial presented detailed data on the clinical parameters that demonstrated the effectiveness of CGGD in the treatment of CNAG with GHSC patients. This study also provided supportive evidence that CNAG with GHSC patients were associated with disturbed branched-chain amino acid metabolism and glycerophospholipid levels, suggesting that CNAG treatment based on TCM syndrome scores was reasonable and also provided a potential pharmacological mechanism of action of CGGD.

Application of Data Mining Technology in the Screening for Gallbladder Stones: A Cross-Sectional Retrospective Study of Chinese Adults.

PURPOSE: The purpose of this study was to use data mining methods to establish a simple and reliable predictive model based on the risk factors related to gallbladder stones (GS) to assist in their diagnosis and reduce medical costs. MATERIALS AND METHODS: This was a retrospective cross-sectional study. A total of 4215 participants underwent annual health examinations between January 2019 and December 2019 at the Physical Examination Center of Shengjing Hospital Affiliated to China Medical University. After rigorous data screening, the records of 2105 medical examiners were included for the construction of J48, multilayer perceptron (MLP), Bayes Net, and Naïve Bayes algorithms. A ten-fold cross-validation method was used to verify the recognition model and determine the best classification algorithm for GS. RESULTS: The performance of these models was evaluated using metrics of accuracy, precision, recall, F-measure, and area under the receiver operating characteristic curve. Comparison of the F-measure for each algorithm revealed that the F-measure values for MLP and J48 (0.867 and 0.858, respectively) were not statistically significantly different (p>0.05), although they were significantly higher than the F-measure values for Bayes Net and Naïve Bayes (0.824 and 0.831, respectively; p<0.05). CONCLUSION: The results of this study showed that MLP and J48 algorithms are effective at screening individuals for the risk of GS. The key attributes of data mining can further promote the prevention of GS through targeted community intervention, improve the outcome of GS, and reduce the burden on the medical system.
