Association of calcific rotator cuff tendinopathy with nephrolithiasis and/or cholelithiasis: A case-control study.

This study aimed to examine the association between calcific rotator cuff tendinopathy (RCT) and nephrolithiasis and/or cholelithiasis. A case-control study was conducted on patients diagnosed with RCT between June 2016 and June 2022. RCT was confirmed by ultrasound, and patients were divided into 2 groups: calcific RCT (case) and non-calcific RCT (control). Data were collected retrospectively from electronic medical records and completed by phone calls, looking for a history of nephrolithiasis and/or cholelithiasis; based on clinical features or incidental findings on abdominal and pelvic imaging. A total of 210 patients with RCT were included. Among the 95 cases of calcific RCT, 43 had a history of lithiasis (45.3%) against 23 (20%) from the non-calcific RCT group (P < .001); 21 patients suffered from nephrolithiasis (22.1%) and 26 had cholelithiasis (27.4%) versus 10 (8.7%) (P = .006) and 16 (13.9%) (P = .015) in the non-calcific RCT group, respectively. Logistic regression showed that the independent predictors of calcific RCT included a history of nephrolithiasis (OR, 4.38; 95% CI: 1.61-11.92, P = .004) and a history of cholelithiasis (OR, 3.83; 95% CI: 1.64-8.94, P = .002). In patients with calcific RCT, the occurrence of lithiasis was significantly associated in the bivariate analysis with higher age, body mass index, fasting blood sugar, and HbA1c (all with P < .05), but only with the presence of another site of calcific tendinopathy than the shoulder (OR, 3.11; 95% CI: 1.12-8.65, P = .03) in the multivariate analysis. Nephrolithiasis and/or cholelithiasis are associated with calcific RCT, and their presence predicts calcific RCT at least 3 times. Further research is required to determine the common risk factors and preventive measures against lithogenesis in patients with calcific RCT, nephrolithiasis, and cholelithiasis.

Cholelithiasis in a goat associated with chronic fascioliosis in Bangladesh: A case report and review of literatures.

The objective of the present study was to describe a very rare case of gallstone (cholelithiasis) in a goat associated with chronic fasciolosis. During a routine slaughterhouse-based survey, a two-and-half-year-old female Black Bengal Goat was found to be affected with severe chronic fascioliosis characterized by the massive damage in the liver. Through systemic dissection of liver, we isolated 94 adult Fasciola spp., and by PCR, we confirmed the fluke as Fasciola gigantica. The gallbladder of the goat was oedematous. On opening the gallbladder, we recovered 255 stones of variable sizes. Stones were whitish in colour and friable, and some of the fragile stones were attached to the wall of the gallbladder. To the authors' knowledge, this is the first report of the cholelithiasis in a goat associated with F. gigantica.

Disasters that develop in the liver due to hydatid cyst: a case report.

Hilar cavernous transformation is the formation of venous structures rich in collateral around the portal vein. Portal vein thrombosis is a rare entity. Although there are many reasons for its etiology, few cases have been reported secondary to hydatid cysts in the liver. Here, we present a 24-year-old patient with complaints of abdominal pain and swelling. Her CT and MRI scans show cholelithiasis with portal vein thrombosis and hilar cavernous transformation due to giant hydatid cyst compression in the lateral liver sector.

La transformación cavernosa hiliar es la formación de estructuras venosas ricas en colaterales alrededor de la vena porta. La trombosis de la vena porta es una afección poco frecuente. Aunque existen muchas razones en su etiología, se han descrito pocos casos secundarios a quiste hidatídico en el hígado. Aquí se presenta el caso de una paciente de 24 años con quejas de dolor abdominal e hinchazón. La tomografía computarizada y la resonancia magnética mostraron colelitiasis con trombosis de la vena porta y transformación cavernosa hiliar por compresión del quiste hidatídico gigante en el sector lateral del hígado.

The association between intakes of dietary trace minerals and gallstone disease: A cross-sectional study from National Health and Nutrition Examination Survey 2017 to 2018.

The gallstone disease is becoming increasingly prevalent worldwide. Dietary trace minerals have been proven to be closely related to many metabolic diseases, and this study aims to explore the association between intakes of dietary trace minerals (copper, iron, selenium, and zinc) and gallstone disease (GSD). Using the National Health and Nutrition Examination Survey (NHANES) from 2017 to 2018, intakes of dietary trace minerals and GSD data were obtained through a 24-hour recall and diagnostic questionnaire, respectively. Weighted logistic regression models were used to identify the association between intakes of dietary trace minerals and the prevalence of GSD, and the results were presented as odds ratios (OR) and 95% confidence intervals (95% CI). A total of 4077 participants were included in the final analysis, of which 456 participants had GSD and 3621 participants serving as the control group. No significant associations between GSD and intakes of dietary trace minerals (iron, selenium, and zinc) were found. However, after adjusting for all covariates, significant association was demonstrated between dietary copper (Cu) intake and GSD (OR = 0.66, 95% CI = 0.45-0.98). After conducting a weighted quantile logistic regression, a significant negative correlation was also found between dietary Cu intake and highest GSD quartile (Q4) (OR = 0.45, 95% CI = 0.26-0.80). Following the research outlined above, no association was found between intakes of dietary trace minerals (iron, selenium, and zinc) and GSD; however, a linear negative association was identified between dietary Cu intake and GSD.

Investigating the influence of the gut microbiome on cholelithiasis: unveiling insights through sequencing and predictive modeling.

BACKGROUND: Cholelithiasis is one of the most common disorders of hepatobiliary system. Gut bacteria may be involved in the process of gallstone formation and are, therefore considered as potential targets for cholelithiasis prediction. OBJECTIVE: To reveal the correlation between cholelithiasis and gut bacteria. METHODS: Stool samples were collected from 100 cholelithiasis and 250 healthy individuals from Huzhou Central Hospital; The 16S rRNA of gut bacteria in the stool samples was sequenced using the third-generation Pacbio sequencing platform; Mothur v.1.21.1 was used to analyze the diversity of gut bacteria; Wilcoxon rank-sum test and linear discriminant analysis of effect sizes (LEfSe) were used to analyze differences in gut bacteria between patients suffering from cholelithiasis and healthy individuals; Chord diagram and Plot-related heat maps were used to analyze the correlation between cholelithiasis and gut bacteria; six machine algorithms were used to construct models to predict cholelithiasis. RESULTS: There were differences in the abundance of gut bacteria between cholelithiasis and healthy individuals, but there were no differences in their community diversity. Increased abundance of Costridia, Escherichia flexneri, and Klebsiella pneumonae were found in cholelithiasis, while Bacteroidia, Phocaeicola, and Phocaeicola vulgatus were more abundant in healthy individuals. The top four bacteria that were most closely associated with cholelithiasis were Escherichia flexneri, Escherichia dysenteriae, Streptococcus salivarius, and Phocaeicola vulgatus. The cholelithiasis model based on CatBoost algorithm had the best prediction effect (sensitivity: 90.48%, specificity: 88.32%, and AUC: 0.962). CONCLUSION: The identification of characteristic gut bacteria may provide new predictive targets for gallstone screening. As being screened by the predictive model, people at high risk of cholelithiasis can determine the need for further testing, thus enabling early warning of cholelithiasis.

[New Progress in Longitudinal Research on the Risk Factors for Cholelithiasis]. / åŸºäºŽçºµå‘ç ”ç©¶çš„èƒ†å›Šç»“çŸ³å‘ç— é£Žé™©å› ç´ ç ”ç©¶æ–°è¿›å±•.

Cholelithiasis is a common disease of the digestive system. The risk factors for cholelithiasis have been reported and summarized many times in the published literature, which primarily focused on cross-sectional studies. Due to the inherent limitations of the study design, the reported findings still need to be validated in additional longitudinal studies. Moreover, a number of new risk factors for cholelithiasis have been identified in recent years, such as bariatric surgery, hepatitis B virus infection, hepatitis C virus infection, kidney stones, colectomy, osteoporosis, etc. These new findings have not yet been included in published reviews. Herein, we reviewed the 101 cholelithiasis-associated risk factors identified through research based on longitudinal investigations, including cohort studies, randomized controlled trials, and nested case control studies. The risk factors associated with the pathogenesis of cholelithiasis were categorized as unmodifiable and modifiable factors. The unmodifiable factors consist of age, sex, race, and family history, while the modifiable factors include 37 biological environmental factors, 25 socioenvironmental factors, and 35 physiochemical environmental factors. This study provides thorough and comprehensive ideas for research concerning the pathogenesis of cholelithiasis, supplying the basis for identifying high-risk groups and formulating relevant prevention strategies.

Therapeutic Potential of Danyankang Capsule in High-Fat Diet-Induced Cholelithiasis and Its Impact on Liver FXR Signaling and Gut Microbiota.

Cholelithiasis, commonly known as gallstones, represents a prevalent hepatobiliary disorder. This study aimed to elucidate the therapeutic role and mechanism of Danyankang capsulein treating cholelithiasis induced by a high-fat diet in C57BL/6 mice. The therapeutical potential of Danyankang was assessed through biochemical analyses, histopathological examinations, protein detection, and 16S rDNA sequencing. A high-fat diet resulted in cholelithiasis manifestation in mice, with discernable abnormal serum biochemical indices and disrupted biliary cholesterol homeostasis. Danyankang treatment notably ameliorated liver inflammation symptoms and rectified serum and liver biochemical abnormalities. Concurrently, it addressed biliary imbalances. Elevated expressions of toll-like receptor 4 (TLR4), nuclear factor-kappaB (NF-κB)/pNF-κB, HMGCR, CYP7A1, and CYP8B1 observed at the inception of cholelithiasis, were notably reduced upon Danyankang administration. Furthermore, 16S rDNA analysis revealed a decline in species number and diversity of the intestinal flora in cholelithiasis-treated mice, while the decline was reversed with Danyankang treatment. Danyankang capsules reduced the abundance of Verrucomicrobiota and increased the abundance of Actinobacteriota and Proteobacteria. In conclusion, the present study demonstrates that Danyankang exerts potent therapeutic efficacy against high-fat diet-induced cholelithiasis. This beneficial outcome is potentially linked to the inhibition of the TLR4/pNF-κB and SHP/CYP7A1/CYP8B1 signaling pathways, as well as the enhancement of intestinal flora species abundance.

Endoscopic features of low-phospholipid-associated cholelithiasis syndrome: A retrospective cohort study.

BACKGROUND AND OBJECTIVE: LPAC (low phospholipid-associated cholelithiasis) syndrome is a rare genetic form of cholelithiasis. ERCP (endoscopic retrograde cholangiopancreatography) is often used to remove gallstones in the bile duct. No published data is available on the role of ERCP in LPAC syndrome. PATIENTS AND METHODS: In this retrospective cohort study, we included patients diagnosed with LPAC syndrome in a single tertiary referral center between 2009 and 2021. Our aim was to assess the frequency, indications, modalities, results, and complications of ERCP, as well as predictive factors for ERCP, in LPAC syndrome. Independent factors associated with ERCP occurrence were identified using a multivariable Cox regression analysis. RESULTS: ERCP was required in 31.2 % of the 269 patients included for analysis. Among patients who required ERCPs, 78.6 % had the procedure before diagnosis (i.e., starting UDCA). Most common indications were choledocholithiasis (53.6 %) and acute cholangitis (29.5 %). Post ERCP pancreatitis, perforation and bleeding rates were 7.2 %, 2.6 %, and 1.3 %, respectively. Age and history of cholelithiasis in first-degree relatives were associated with a higher risk of ERCP (Hazard-ratio [HR]=1.30 [95 %confidence-interval [CI] 1.04-1.62] and HR=1.88 [95 %CI 1.15-3.07] respectively). Female gender and UDCA intake ≥ 1 year were associated with a lower risk of ERCP (HR=0.49 [95 %CI 0.29-0.82] and HR=0.44 [95 %CI 0.22-0.90] respectively). Median follow-up was 10.8 years. CONCLUSION: One-third of patients with LPAC syndrome undergo sphincterotomy. However, most procedures are performed before diagnosis and UDCA is associated with a lower risk of endoscopic procedure. Earlier diagnosis and treatment with UDCA may further reduce the need for ERCP in patients with LPAC syndrome.

Association between sarcopenia-related markers and cholelithiasis: A prospective and Mendelian randomization study.

Cholelithiasis is a common digestive disease that drives a myriad of adverse complications. The correlation between sarcopenia and various digestive disorders has been extensively researched, whereas its association with cholelithiasis remains unreported. We aimed to investigate the association through prospective and Mendelian randomization (MR) analyses and establish a quantitative score reflecting the impact of sarcopenia-related markers on cholelithiasis. The prospective study involved 448 627 participants from the UK Biobank. Cox proportional hazard models were employed to investigate the correlation between sarcopenia-related markers and cholelithiasis. To quantitatively assess cholelithiasis risk, the SARCHO score was derived from a multivariable Cox model. Bidirectional two-sample MR analysis was conducted to validate the causal association. A total of 16 738 individuals developed cholelithiasis during a median follow-up of 12 years. Hazard ratios (HRs) of cholelithiasis decreased stepwise over skeletal muscle index tertiles (highest tertile: reference; middle tertile: 1.23, p < .001; lowest tertile: 1.33, p < .001). The tertiles of grip strength showed a similar pattern. Individuals with slow walking pace had a higher risk of cholelithiasis compared to those with normal walking pace (HR 1.23; p < .001). Our SARCHO score better quantifies the risk of cholelithiasis. MR analysis showed a causal relationship between muscle mass and cholelithiasis (OR 0.81; p < .001). No causal effect of cholelithiasis on lean mass was observed. Prospective and MR analyses have consistently demonstrated an increased risk of cholelithiasis in individuals with decreased muscle mass. Additionally, SARCHO score further quantified the cholelithiasis occurrence risk. These findings provide compelling evidence for muscle strengthening in preventing cholelithiasis.

TyG index is positively associated with HOMA-IR in cholelithiasis patients with insulin resistance: Based on a retrospective observational study.

BACKGROUND/OBJECTIVE: Cholelithiasis is a common disease but pose significant global health and financial burdens. Mechanisms of the disease are associated with insulin resistance (IR), obesity, metabolic syndrome, and type 2 diabetes. Insulin resistance is commonly observed in cholelithiasis patients. More recently, the triglyceride-glucose (TyG) index has been proposed as an alternative marker of insulin resistance. In our study we aimed to understand whether the TyG index is correlated with HOMA-IR in cholelithiasis patients. And also we aimed the predict a cutoff value for determining insulin resistance in cholelithiasis patients. METHODS: A total of 184 cholelithiasis patients were matched in terms of age, gender, and BMI. They were divided into two groups based on their Homa IR levels (IR and Non-IR group). This study was a retrospective, observational study and clinical data was obtained from electronic medical records. Cutoff value for Tyg index was established through ROC Analysis. Binary Logistic Regression was used to identify factors affecting insulin resistance. RESULTS: A significant cutoff value was found for the TyG index in determining the presence of insulin resistance. Having a TyG index of ≥8.71 indicates the presence of insulin resistance. The sensitivity was 68.48%, the specificity was 58.70%. Binary Logistic Regression analyses showed that an increase in Tyg Index, waist circumference and waist-to-height ratio values increases the risk of insulin resistance by 2.705 (p = 0.001), 1.032 (p = 0.029), and 334.057 (p = 0.012) times respectively. CONCLUSION: Our study indicated that TyG index is positively correlated with HOMA-IR. TyG index was found as a risk factor for insulin resistance.

Independent association of general and central adiposity with risk of gallstone disease: observational and genetic analyses.

Background: General obesity is a well-established risk factor for gallstone disease (GSD), but whether central obesity contributes additional independent risk remains controversial. We aimed to comprehensively clarify the effect of body fat distribution on GSD. Methods: We first investigated the observational association of central adiposity, characterized by waist-to-hip ratio (WHR), with GSD risk using data from UK Biobank (N=472,050). We then explored the genetic relationship using summary statistics from the largest genome-wide association study of GSD (ncase=43,639, ncontrol=506,798) as well as WHR, with and without adjusting for body mass index (BMI) (WHR: n=697,734; WHRadjBMI: n=694,649). Results: Observational analysis demonstrated an increased risk of GSD with one unit increase in WHR (HR=1.18, 95%CI=1.14-1.21). A positive WHR-GSD genetic correlation (rg =0.41, P=1.42×10-52) was observed, driven by yet independent of BMI (WHRadjBMI: rg =0.19, P=6.89×10-16). Cross-trait meta-analysis identified four novel pleiotropic loci underlying WHR and GSD with biological mechanisms outside of BMI. Mendelian randomization confirmed a robust WHR-GSD causal relationship (OR=1.50, 95%CI=1.35-1.65) which attenuated yet remained significant after adjusting for BMI (OR=1.17, 95%CI=1.09-1.26). Furthermore, observational analysis confirmed a positive association between general obesity and GSD, corroborated by a shared genetic basis (rg =0.40, P=2.16×10-43), multiple novel pleiotropic loci (N=11) and a causal relationship (OR=1.67, 95%CI=1.56-1.78). Conclusion: Both observational and genetic analyses consistently provide evidence on an association of central obesity with an increased risk of GSD, independent of general obesity. Our work highlights the need of considering both general and central obesity in the clinical management of GSD.

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.

CLINICAL AND PATHOLOGIC FINDINGS IN IGUANIDS WITH SODIUM URATE CHOLELITHIASIS.

Four green iguanas (Iguana iguana) and one blue iguana (Cyclura lewisi) from five facilities were diagnosed with sodium urate cholelithiasis. One case was diagnosed antemortem via ultrasonography, and the iguana underwent a choledochotomy for treatment. The other four cases were identified at necropsy. Pathologic hepatic and biliary changes were present in four of the five cases at necropsy. Histologically, four iguanas had hepatic fibrosis, three had bile duct hyperplasia, and one had cholangiohepatitis and pancreaticocholedochitis. Two iguanas had pathologic renal changes. This is the first report of sodium urate cholelithiasis in reptiles. This case series highlights the potential significant clinical disease caused by sodium urate cholelithiasis and the importance of biliary system evaluation. Further investigation is recommended to explore the pathogenesis of reptilian sodium urate cholelith formation.

Mirizzi syndrome: Problems and strategies.

Mirizzi syndrome is a serious complication of gallstone disease. It is caused by the impacted stones in the gallbladder neck or cystic duct. One of the features of Mirizzi syndrome is severe inflammation or dense fibrosis at the Calot's triangle. In our clinical practice, bile duct, branches of right hepatic artery and right portal vein clinging to gallbladder infundibulum are often observed due to gallbladder infundibulum adhered to right hepatic hilum. The intraoperative damage of branches of right hepatic artery occurs more easily than that of bile duct, all of which are hidden pitfalls for surgeons. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) are the preferable tools for the diagnosis of Mirizzi syndrome. Anterograde cholecystectomy in Mirizzi syndrome is easy to damage branches of right hepatic artery and bile duct due to gallbladder infundibulum adhered to right hepatic hilum. Subtotal cholecystectomy is an easy, safe and definitive approach to Mirizzi syndrome. When combined with the application of ERCP, a laparoscopic management of Mirizzi syndrome by well-trained surgeons is feasible and safe. The objective of this review was to highlight its existing problems: (1) low preoperative diagnostic rate, (2) easy to damage bile duct and branches of right hepatic artery, and (3) high concomitant gallbladder carcinoma. Meanwhile, the review aimed to discuss the possible therapeutic strategies: (1) to enhance its preoperative recognition by imaging findings, and (2) to avoid potential pitfalls during surgery.

Effect of various dietary fructose concentrations on the gallstone formation process in mice / Efecto de diversas concentraciones de fructosa dietética en el proceso de formación de cálculos biliares en ratones

Background: little information is availaible on the effect of fructose on bile lipids. The first stage in the formation of gallstones corresponds tobiliary cholesterol crystallization, derived from the vesicular transporters. The aim of this study was to investigate the influence of consumingdiets with different fructose concentrations on serum lipids and their implications on gallstones formation. Methods: BALB/c mice divided into a control group as well as groups were treated with different fructose concentrations (10 %, 30 %, 50 % or70 %) for different periods (1, 2 or 5 months). Blood, liver and bile samples were obtained. In bile samples, cholesterol and phospholipids levelswere analyzed, and cholesterol transporters (vesicles and micelles) were separated by gel filtration chromatography. Results: treated animals showed: 1) increases in body weight similar to the control group; 2) a significant increase in plasma triglycerides only atvery high fructose concentrations; 3) a significant increase in total serum cholesterol in the treatment for 1 month; 4) no variations in HDL-cho-lesterol; 5) a significant increase in serum glucose only at very high fructose concentrations in the second month of treatment; 6) no differencesin the plasma alanine-aminotransferase activity; 7) a significant increase in liver triglyceride levels only at very high fructose concentrations; 8)no change in biliary lipid concentrations or in micellar and vesicular phospholipids.Conclusion: changes in plasma, liver and bile lipids were only observed at very high fructose concentrations diets. We conclude that fructoseapparently does not alter the gallstone formation process in our experimental model.(AU)

Introducción: se dispone de escasa información sobre el efecto de la fructosa sobre los lípidos biliares. La primera etapa en la formación decálculos biliares corresponde a la cristalización del colesterol biliar, derivado de los transportadores vesiculares. El objetivo de este estudio fueinvestigar la influencia del consumo de dietas con diferentes concentraciones de fructosa en los lípidos séricos y sus implicaciones en el procesode formación de cálculos biliares.Métodos: ratones BALB/c fueron tratados con diferentes concentraciones de fructosa (10 %, 30 %, 50 % o 70 %) durante diferentes períodos(1, 2 o 5 meses). Se obtuvieron muestras de sangre, hígado y bilis. En muestras de bilis se analizaron los niveles de colesterol y fosfolípidos, ylos transportadores de colesterol (vesículas y micelas) se separaron mediante cromatografía de filtración en gel.Resultados: los animales tratados mostraron: 1) aumentos en el peso corporal similares al grupo de control; 2) aumento significativo en lostriglicéridos plasmáticos sólo a concentraciones muy altas de fructosa; 3) aumento significativo del colesterol sérico total en el tratamientodurante 1 mes; 4) ninguna variación en los niveles de HDL-colesterol; 5) aumento significativo en glucosa sérica solo a concentraciones muyaltas de fructosa; 6) ninguna diferencia en la actividad de la alanina-aminotransferasa plasmática; 7) aumento significativo en los niveles detriglicéridos hepáticos sólo a concentraciones muy altas de fructosa; 8) ningún cambio en las concentraciones de lípidos biliares o en los fos-folípidos micelares y vesiculares.Conclusión: se observaron cambios en los lípidos plasmáticos, hígado y bilis sólo en dietas con concentraciones muy altas de fructosa. Con-cluimos que la fructosa aparentemente no altera el proceso de formación de cálculos biliares en nuestro modelo experimental.(AU)

Acute pancreatitis presented with diffuse ST-segment elevation: A case report and literature review.

INTRODUCTION: Although electrocardiographic changes have been previously reported in patients with acute pancreatitis, diffuse ST-segment elevation without occluded coronary arteries is rarely documented. PATIENT CONCERNS: A 45-year-old man presented to our emergency department due to persistent epigastric pain for 2 hours. However, ECG in the emergency department revealed regular sinus rhythm at 67 beats per minute, peaked T waves in lead V3-5, and upsloping ST-segment elevation in leads II, III, aVF, and V2-6. DIAGNOSIS: He was diagnosed with acute pancreatitis and presented with diffuse ST-segment elevation. INTERVENTIONS: Laboratory workup and computed tomography supported the diagnosis of acute gallstone pancreatitis and endoscopic retrograde cholangiopancreatography was performed. Coronary angiography showed patent coronary arteries finally. OUTCOMES: Endoscopic retrograde cholangiopancreatography and endoscopic papillo-sphincterotomy were performed, and the stone in the common bile duct was removed smoothly without immediate complication. Due to his relatively stable condition, he was discharged on day 7 of admission. CONCLUSION: We presented an uncommon case of acute pancreatitis demonstrating similar features of AMI. This reminds cardiologists and emergency physicians to make the judgment with more caution to avoid jumping to conclusions and providing inappropriate treatment.
