Phospholipid and glycerolipid metabolism as potential diagnostic biomarkers for acute pancreatitis.

BACKGROUND: Acute pancreatitis (AP) is characterized as a systemic inflammatory condition posing challenges in diagnosis and prognosis assessment. Lipid metabolism abnormalities, especially triacylglycerol (TAG) levels, have been reported, indicating their potential as biomarkers in acute pancreatitis. However, the performance of the TAG cycle, including phospholipid and glycerolipid metabolism, in AP patients has not yet been reported. METHODS: This study enrolled 91 patients with acute biliary pancreatitis (ABP), 27 with hyperlipidaemic acute pancreatitis (HLAP), and 58 healthy controls (HCs), and their plasma phospholipid and glycerolipid levels were analyzed through liquid chromatography‒mass spectrometry. The phospholipid and glycerolipid contents of plasma collected from AP patients on the first, third, and seventh days of hospitalization were also measured. An orthogonal partial least squares discriminant analysis model served to differentiate the ABP, HLAP and HC groups, and potentially diagnostic lipids were evaluated via receiver operating characteristic curves in both the test and validation sets. Correlations between clinical data and lipids were conducted using Spearman's method. Clustering via the 'mfuzz' R package and the Kruskal‒Wallis H test were conducted to monitor changes during hospitalization. RESULTS: Compared with those in HCs, the levels of phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidic acid (PA) were lower in AP patients, whereas the levels of phosphatidylinositol (PI) and phosphatidylglycerol (PG) showed the opposite trend. Interestingly, TAG levels were positively correlated with white blood cell counts in ABP patients, and TAGs containing 44-55 carbon atoms were highly correlated with plasma TAG levels in HLAP patients. Phospholipid levels exhibited an inverse correlation with AP markers, in contrast to glycerolipids, which demonstrated a positive correlation with these markers. Additionally, PE (O-16:0/20:4) and PE (18:0/22:6) emerged as potential biomarkers because of their ability to distinguish ABP and HLAP patients from HCs, showing area under the curve (AUC) values of 0.932 and 0.962, respectively. PG (16:0/18:2), PG (16:0/20:4), PE (P-16:0/20:2), PE (P-18:2/18:2), PE (P-18:1/20:3), PE (P-18:1/20:4), PE (O-16:0/20:4), and TAG (56:6/FA18:0) were significantly changed in ABP patients who improved. For HLAP patients, PC (18:0/20:3), TAG (48:3/FA18:1), PE (P-18:0/16:0), and TAG (48:4/FA18:2) showed different trends in patients with improvement and deterioration, which might be used for prognosis. CONCLUSIONS: Phospholipids and glycerolipids were found to be potential biomarkers in acute pancreatitis, which offers new diagnostic and therapeutic insights into this disease.

Association between serum triglyceride level and severity of acute biliary pancreatitis.

BACKGROUND: Acute biliary pancreatitis (ABP) is the most common type of acute pancreatitis. However, the effect of serum triglyceride (TG) levels on the severity of ABP remains unclear. The aim of this study was to assess the correlation between serum TG levels and the severity of ABP. METHODS: Data from 526 ABP patients was analyzed in this study. The patients were divided into normal and elevated groups according to the TG level measured within 24 h after admission, and the elevated group was further divided into mild, moderate, and severe elevated groups. The demographic data and clinical outcomes of each group were compared. RESULTS: Of the 526 ABP patients, 394 were in the normal TG group and 132 were in the elevated TG group (36 mild, 57 moderate, and 39 severe). The elevated group was younger (51.5 ± 12.9 vs. 58.9 ± 13.9), predominantly male (66.7% vs. 45.2%), had more history of diabetes (22.7% vs. 12.4%) and hyperlipidemia (19.7% vs. 0.8%), and developed systemic inflammatory response syndrome (SIRS) (25.8% vs. 15.5%), persistent organ failure (POF) (11.4% vs. 2.8%), and local complications (62.9% vs. 42.1%) more frequently compared to the normal group (P < 0.05). The incidence of SIRS, POF, acute peripancreatic fluid collection (APFC), and acute necrotic collection (ANC) increased with increasing TG levels (Ptrend < 0.05). In multivariate analysis, TG was independently associated with POF, APFC, and ANC in increments of 100 mg/dl (P < 0.05), and there was a linear relationship between TG levels and POF, APFC, and ANC (non-linear P > 0.05, P overall <0.05). In addition, nonalcoholic fatty liver disease is not a risk factor for POF, ANC, and APFC in ABP patients. CONCLUSIONS: Elevated serum TG levels were independently associated with more severe ABP. The incidence of POF, APFC, and ANC in ABP patients increased with the increase of TG levels, with a linear relationship.

Association between neutrophil to high-density lipoprotein cholesterol ratio and disease severity in patients with acute biliary pancreatitis.

BACKGROUND: The neutrophil to high-density lipoprotein cholesterol ratio (NHR) is independently associated with the severity of various diseases. However, its association with acute biliary pancreatitis (ABP) remains unknown. METHODS: This study included 1335 eligible patients diagnosed with ABP from April 2016 to December 2022. Patients were divided into low- and high-NHR level groups using an optimal cut-off value determined utilizing Youden's index. Multivariate logistic regression analysis was used to investigate the correlation between NHR and ABP severity. Multivariate analysis-based limited restricted cubic spline (RCS) method was used to evaluate the nonlinear relationship between NHR and the risk of developing moderate or severe ABP. RESULTS: In this study, multivariate logistic regression analysis indicated an independent association between NHR and ABP severity (p < .001). The RCS analysis showed a linear correlation between NHR and the risk of developing moderate or severe ABP (P for non-linearity > 0.05), and increased NHR was found to be independently associated with a more severe form of the disease. CONCLUSIONS: Our study suggests that NHR is a simple and practical independent indicator of disease severity, serving as a potential novel predictor for patients with ABP.

This study is the first to report on the independent association between the neutrophil to high-density lipoprotein cholesterol ratio (NHR) and acute biliary pancreatitis (ABP) severity.The restricted cubic spline analysis showed a linear correlation between NHR and the risk of developing moderate or severe ABP.Increased NHR levels are independently associated with a more severe degree of the disease.

Performance of European and American Societies of Gastrointestinal Endoscopy Guidelines for Prediction of Choledocholithiasis in Patients with Acute Biliary Pancreatitis.

Background and Objectives: Up to one-third of patients with acute biliary pancreatitis also present with choledocholithiasis. Guidelines from the European Society of Gastrointestinal Endoscopy (ESGE) and the American Society for Gastrointestinal Endoscopy (ASGE) for investigating suspected choledocholithiasis suggest endoscopic retrograde cholangiopancreatography in patients with high-likelihood (ESGE)/high-probability (ASGE) predictors and endoscopic ultrasound in those with intermediate-likelihood (ESGE)/intermediate-probability (ASGE) predictors. Although both guidelines are similar, they are not identical. Furthermore, these algorithms were mainly developed from cohorts of patients without pancreatitis and are therefore poorly validated in a subset of patients with acute pancreatitis. We aimed to assess the performance of the ESGE and ASGE algorithms for the prediction of choledocholithiasis in patients with acute biliary pancreatitis. Materials and Methods: This was a retrospective analysis of 86 consecutive patients admitted to a tertiary referral centre in the year 2020 due to acute biliary pancreatitis. Results: Choledocholithiasis was confirmed in 29/86 (33.7%) of patients (13 with endoscopic retrograde cholangiopancreatography and 16 with endoscopic ultrasound). All 10/10 (100%) ESGE high-likelihood and 14/19 (73.7%) ASGE high-probability patients had choledocholithiasis. Only 19/71 (26.8%) patients with ESGE intermediate likelihood and 15/67 (22.4%) with ASGE intermediate probability had choledocholithiasis. Only 8/13 (61.5%) patients with the ASGE high-probability predictor of dilated common bile duct plus bilirubin > 68.4 µmol/mL had choledocholithiasis. Since this predictor is not considered high likelihood by ESGE, this resulted in a superior specificity of the European compared to the American guideline (100% vs. 91.2%). Following the American instead of the European guidelines would have resulted in five unnecessary endoscopic retrograde cholangiopancreatographies and five unnecessary endoscopic ultrasound examinations. Conclusions: This retrospective analysis suggests that the European guidelines may perform better than the American guidelines at predicting choledocholithiasis in the setting of acute pancreatitis. This was because dilated common bile duct plus bilirubin > 68.4 µmol/mL was not a reliable predictor for persistent bile duct stones.

Clinical characteristics of three distinct types of pancreatitis with overlapping etiologies: A ten-year retrospective cohort study.

BACKGROUND: Hypertriglyceridemia (HTG) is frequently observed in non-HTG-induced acute pancreatitis (AP), such as in the early stage of acute biliary pancreatitis (ABP). There is overlap in the etiologies of ABP, HTG-AP, and biliary-hypertriglyceridemia acute pancreatitis (BHAP), which may be perplexing for clinicians. METHODS: We retrospectively analyzed 394 AP patients. The patients were divided into three groups based on etiology. We analyzed the differences among the three groups of patients in terms of general information, laboratory parameters, and prognosis. RESULTS: The mean age of patients in the ABP group was significantly higher than that in the HTG-AP and BHAP groups (p < 0.001). Females made up a greater percentage of the ABP group, whereas males made up the majority in the HTG-AP and BHAP groups. The ABP group had the highest PCT, AMS, LPS, ALT, AST, GGT, TBIL, DBIL, APACHE II, and BISAP scores. TG and BMI were highest in the HTG-AP group. AST and GGT levels were substantially greater in BHAP patients than those in HTG-AP. The BHAP group had the greatest incidence of organ failure, systemic complications, and local complications. CONCLUSION: ABP usually develops in people aged 50-59 years. HTG-AP primarily affects people aged 30-39 years. However, the peak incidence age of BHAP falls between the two aforementioned age groups (40-49 years). We also found that patients with BHAP seem to be in an intermediate state in terms of some biochemical markers and demographic characteristics. Furthermore, BHAP may have the worst clinical outcomes compared with HTG-AP and ABP.

Acute pancreatitis: It can be the first sign of silent gallstones.

Objectives: The management of asymptomatic cholelithiasis is controversial. Silent gallstones are generally assumed to cause complications after at least one episode of biliary colic. The ratio of those silent stones that had initially caused, -or were diagnosed as the etiological agent of- acute pancreatitis has not been reported in the literature yet. Our study was designed to investigate the ratio of asymptomatic cholelithiasis in acute biliary pancreatitis cases. Material and Methods: One hundred and seventy-one patients of 305 cases, who were followed up with the diagnosis of acute biliary pancreatitis, were identified retrospectively. Demographic specifications, laboratory findings and clinical progressions of the patients were inspected. Clinical histories were detailed by phone calls. Gallstones were radiologically detected in 85 out of 171 cases. Those patients were divided as symptomatic and asymptomatic. Clinical findings and follow-ups were evaluated by "Chi-square" test. Results: In the study group, 80% of the patients were asymptomatic (n= 68) and 16.47% of the patients (n= 14) had complicated pancreatitis. Regarding the severity of the clinical course, being symptomatic or not was not identified as a significant factor (p= 0.108). In regard of creating symptoms, the size of the stone was not significant (p= 0.561) and obtained no prediction about the clinical severity of the pancreatitis (p= 0.728). Conclusion: Asymptomatic cholelithiasis patients had a major percentage in acute biliary pancreatitis cases. The "wait and see" approach should be re-evaluated for silent gallstones in prospective trials.

Effect of Frailty on the Management of Suspected Choledocholithiasis.

INTRODUCTION: The American Society for Gastrointestinal Endoscopy and The Society of American Gastrointestinal and Endoscopic Surgeons (ASGE-SAGES) guidelines for managing choledocholithiasis (CDL) omit patient-specific factors like frailty. We evaluated how frail patients with CDL undergoing same-admission cholecystectomy were managed within ASGE-SAGES guidelines. METHODS: We analyzed patients undergoing same-admission cholecystectomy for CDL and/or acute biliary pancreatitis (ABP) from 2016 to 2019 at 12 US academic medical centers. Patients were grouped by Charlson comorbidity index into non-frail (NF), moderately frail (MF), and severely frail (SF). ASGE-SAGES guidelines stratified likelihood of CDL and were used to compare actual to suggested management. Rate of guideline deviation was our primary outcome. Secondary outcomes included rates of surgical site infections (SSIs), biliary leaks, and 30-day surgical readmissions. Rates are presented as NF, MF, and SF. RESULTS: Among 844 patients, 43.3% (n = 365) were NF, 25.4% (n = 214) were MF, and 31.4% (n = 265) were SF. Frail patients were older (33y vs 56.7y vs 73.5y, P < .0001) and more likely to have ABP (32.6% vs 47.7% vs 43.8%, P = .0005). As frailty increased, guideline deviation increased (41.1% vs 43.5% vs 53.6%, P < .006). Severe frailty was predictive of guideline deviation compared to MF (aOR 1.47, 95% CI 1.02-2.12, P = .04) and NF (aOR 1.46, 95% CI 1.01-2.12, P = .04). There was no difference in SSIs (P = .2), biliary leaks (P = .7), or 30-day surgical readmission (P = .7). CONCLUSION: Frail patients with common bile duct stones had more management deviating from guidelines yet no difference in complications. Future guidelines should consider including frailty to optimize detection and management of CDL in this population.

Values of different biochemical indices and clinical scoring systems for the assessment of acute biliary pancreatitis in a Chinese population.

OBJECTIVE: To investigate values of biochemical indices and clinical scoring systems for the assessment of acute biliary pancreatitis (ABP). METHODS: Clinical characteristics, laboratory values including procalcitonin (PCT), and radiologic examinations of all ABP patients with mild acute pancreatitis (MAP), moderately severe acute pancreatitis (MSAP), or severe acute pancreatitis (SAP) were recorded within 48 hours after the onset of acute pancreatitis. Scores of the Accuracy of Acute Physiology and Chronic Health Evaluation (APACHE) II, Bedside Index of Severity in Acute Pancreatitis (BISAP), Computed Tomography Severity Index (CTSI), Ranson, Japanese Severity Score (JSS), Pancreatitis Outcome Prediction (POP) Score and Systemic Inflammatory Response Syndrome (SIRS) score were then calculated. The area under the curve (AUC) of the Receiver Operating Characteristic (ROC) curve was used to analyze the predictive values of biochemical indexes and scoring systems for ABP severity and organ failure. RESULTS: The percentage of patients over 60 in the SAP group was higher than in the MAP and MSAP groups. PCT had the highest value for predicting SAP (AUC = 0.84, P < 0.001) and organ failure (AUC = 0.87, P < 0.001). The AUCs of APACHE II, BISAP, JSS and SIRS for predicting severity were 0.87, 0.83, 0.82, and 0.81, respectively (all P < 0.001). As for organ failure, the AUCs were 0.87, 0.85, 0.84, and 0.82, respectively (all P < 0.001). CONCLUSIONS: PCT has a high value for predicting ABP severity and organ failure. Among the clinical scoring systems, BISAP and SIRS are more suitable for early assessment of AP; while APACHE II and JSS are more suitable for monitoring disease progression after thorough examination.

Predictive model of persistent choledocholithiasis in patients with acute biliary pancreatitis / Modelo predictivo de coledocolitiasis persistente en pacientes con pancreatitis aguda biliar

Background: Choledocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP. Methods: This retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013–2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC. Results: Patients underwent MRCP (n=145, 71.1), MRCP and ERCP (n=44, 21.56%), EUS and ERCP (n=1, 0.49%), or ERCP (n=14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p<0.001; OR=27; 95% CI: 5.8–185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72h (p=0.008; OR=3.4; 95% CI: 1.5–8.9); and biliary sludge in the gallbladder (p=0.008; OR=0.03; 95% CI: 0.001–0.3). Conclusions: The predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results. Conclusions: The predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.(AU)

Antecedentes: La coledocolitiasis que provoca una pancreatitis aguda biliar (PAB) puede migrar al duodeno o persistir en el conducto biliar común (CBC). Desarrollamos un modelo para predecir la coledocolitiasis persistente (CP) en pacientes con PAB. Métodos: Este estudio de cohortes retrospectivo incluyó a 204 pacientes, edad ≥ 18 años (edad media: 73 años, 65,7% mujeres), ingresados por PAB entre los años 2013 y 2018, a los que se les realizó al menos una colangiopancreatografía por resonancia magnética (CPRM), una ultrasonografía endoscópica (USE) o una colangiopancreatografía retrógrada endoscópica (CPRE). Se compararon variables epidemiológicas, analíticas, de imagen y endoscópicas entre pacientes con y sin CP. Se realizaron análisis de regresión logística multivariante para desarrollar un modelo predictivo de CP. Resultados: Los pacientes se sometieron a CPRM (n=145, 71,1%), CPRM y CPRE (n=44, 21,56%), USE y CPRE (n=1, 0,49%) o CPRE (n=14, 6,86%). Se detectó CP en 49 pacientes (24%). La CP se asoció fuertemente con la dilatación del colédoco, detectada en la ecografía de urgencias (p <0,001; OR=27; IC del 95%: 5,8-185,5), aumento de los niveles sanguíneos de gamma glutamil transpeptidasa, detectados a las 72h (p=0,008; OR=3,4, IC del 95%: 1,5-8,9), y barro biliar en la vesícula (p=0,008; OR=0,03; IC del 95%: 0,001-0,3). El modelo predictivo alcanzó un área bajo la curva validada de 0,858 para la detección de CP en pacientes con PAB. Se desarrolló un nomograma basado en los resultados del modelo. Conclusiones: El modelo predictivo fue altamente efectivo en la detección de CP en pacientes con PAB. Por lo tanto, este modelo podría ser útil en la práctica clínica.(AU)

The role and timing of endoscopic retrograde cholangiopancreatography in acute biliary pancreatitis without cholangitis: A nationwide analysis.

BACKGROUND/PURPOSE: The role and optimal timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis without cholangitis (ABPwoC) remains unclear. Using a large national database, we aimed to examine hospitalization outcomes of patients with ABPwoC as a function of the performance and timing of ERCP. METHODS: This was a retrospective study of adult patients with ABPwoC utilizing the National Inpatient Sample from 2016-2017. Patients who underwent inpatient ERCP were stratified into performance: within 24, 24-48, 48-72, and >72 h of hospital admission. The primary outcome was all-cause inpatient mortality as a function of the performance and timing of ERCP; secondary outcomes, including healthcare utilization, were assessed. Multivariate modeling was used to adjust for potential confounders. Statistical analyses were conducted using STATA, version 16.0. RESULTS: Of the 70 030 patients with ABPwoC, 31.37% underwent inpatient ERCP. Performance (aOR: 0.6, p < .05), but not timing (aOR: 0.98, p = .9), of inpatient ERCP was associated with significantly lower all-cause inpatient mortality. Urgent ERCP (within 24 h) was associated with shorter hospital length of stay, lower charges and cost, and less need for pancreatic drainage procedures, while ERCP within 72 h was associated with less frequent intensive care unit admission (all p < .05). DISCUSSION: Based on this large, nationwide analysis, inpatient ERCP for ABPwoC is associated with lower all-cause mortality. ERCP within 24 and 72 h, though not associated with lower mortality, are associated with multiple improved clinical outcomes, including lower healthcare charges and costs.

Predictive model of persistent choledocholithiasis in patients with acute biliary pancreatitis.

BACKGROUND: Choledocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP. METHODS: This retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013-2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC. RESULTS: Patients underwent MRCP (n=145, 71.1), MRCP and ERCP (n=44, 21.56%), EUS and ERCP (n=1, 0.49%), or ERCP (n=14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p<0.001; OR=27; 95% CI: 5.8-185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72h (p=0.008; OR=3.4; 95% CI: 1.5-8.9); and biliary sludge in the gallbladder (p=0.008; OR=0.03; 95% CI: 0.001-0.3). CONCLUSIONS: The predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results. CONCLUSIONS: The predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.

Benign biliary strictures associated with acute biliary pancreatitis.

BACKGROUND AND AIMS: There are limited data about the benign biliary strictures (BBS) which can develop during the clinical course of acute biliary pancreatitis (ABP) due to compression of the common bile duct (CBD) by edematous and inflamed pancreatic tissue. We aimed to determine the incidence of BBS due to ABP and its clinical course after endoscopic management. METHODS: The study was retrospectively conducted among patients with ABP who were admitted to a single tertiary reference center during 3 years. BBS-ABP was defined as distal narrowing of the CBD with proximal dilatation and delayed drainage of the contrast into the duodenum. Endoscopic treatment was performed by inserting a single 7F or 10F plastic stent which was exchanged every 3 months until stricture resolution. Patients were followed for 1 year after stricture resolution. RESULTS: Seven hundred and twenty-one patients had ABP during the study period. Among them, 257 (35.6%) patients underwent ERCP and 26 patients (3.6%) had CBD stricture due to ABP. A 7 Fr plastic stent was inserted in 18 patients and 10 Fr in 8 patients. The stricture was completely resolved at 3 months in 66.7%, at 6 months 23.8% and at 9 months (9.5%) of the patients. There was no procedure-related complications other than asymptomatic stent migration in 4 (19%) patients. None of the patients had recurrent biliary stricture during the 1 year stent-free follow-up period. CONCLUSION: BBS-ABP is a frequently seen clinical entity. In most patients, the stricture improves within 3 months and temporary endoscopic stenting prevents the patients from the consequences of the obstruction during this period.

The clinical significance of body mass index in the early evaluation of acute biliary pancreatitis.

Objective: Obesity has increased across the globe in recent years and is considered an established risk factor for many diseases. The main objective was to investigate the early assessment value of Body Mass Index (BMI) in the prediction of severity in acute biliary pancreatitis (ABP) and by using BMI to evaluate the severity of ABP. Methods: The retrospective analysis was designed to assess the relationship between Body Mass Index and the severity of acute pancreatitis in Beijing Jishuitan Hospital from January 2019 to December 2021. The SPSS 24.0 software was used for statistical analysis, Logistic Regression, and ROC curve for the factors affecting the severity of acute biliary pancreatitis. Results: A total of 259 ABP patients were analyzed in our study. The BMI was significantly correlated with the Ranson scoring and MCTSI scoring (p = 0.000, 0.000). The difference in BMI in different severity of ABP patients was statistically significant (p = 0.000). The Logistic Regression analyses confirmed that BMI was an independent risk factor for the severity of ABP (p = 0.035). Combined detection of BMI, WBC, serum calcium, and SAMY in prognosis of the severity of acute pancreatitis positive rate is higher than single positive rate. Conclusion: The BMI gradually increased with the severity of acute pancreatitis and was an independent risk factor for the condition. Combined detection of BMI and medical tests can effectively improve acute pancreatitis patients' clinical diagnostic accuracy and early treatment, and help to reduce complications.

Outcomes of delayed versus early endoscopic intervention for acute biliary pancreatitis with non-severe acute cholangitis.

BACKGROUND: Despite previous studies on endoscopic interventions in patients with acute biliary pancreatitis (ABP), the optimal time to perform endoscopic retrograde cholangiopancreatography (ERCP) for ABP with non-severe acute cholangitis (AC) remains controversial. METHODS: We performed a retrospective cohort analysis of patients with concurrent ABP and non-severe AC. The patients were divided into two groups: those who underwent ERCP ≤ 72 h after admission (early ERCP group) and those who underwent ERCP > 72 h after admission (delayed ERCP group). The primary outcomes were the technical success rate and ERCP-related complications. RESULTS: The study involved 164 patients (early ERCP, n = 70; delayed ERCP, n = 94) who were treated from 1 December 2 to 2016 to 12 December 2021. The patients' baseline characteristics were not significantly different between the two groups. The technical success rate of ERCP was similar between the two groups (94.29% vs. 97.87%, p = 0.43). Morbidity was also similar between the two groups (p = 0.83). There was no significant difference in the total hospital stay (p = 0.13). However, the early ERCP group had a longer post-ERCP hospital stay (p < 0.001). CONCLUSION: This retrospective analysis showed that delayed ERCP performed > 72 h after admission has economic and safety outcomes similar to those of early ERCP for patients with concurrent ABP and non-severe AC.

Prognostic Significance of the Red Cell Distribution Width/Albumin Ratio in the Prediction of the Severity of Acute Biliary Pancreatitis: A Preliminary Report.

Objective Acute pancreatitis (AP) is a common inflammatory disease that should be considered in the etiology of patients presenting to the emergency department with abdominal pain. AP manifests with a clinical picture that can lead to organ failure and even death; therefore, early diagnosis and treatment are essential. In this study, we aimed to evaluate the red cell distribution width (RDW)/albumin ratio (RAR), which, we consider, can be used to determine the clinical course of acute biliary pancreatitis (ABP). Material and method The study included 166 patients with ABP. The patient's demographic information, blood values at the time of the first presentation to the emergency department, and radiological results were recorded by screening them retrospectively. Using the Atlanta criteria, the cases were classified into mild, moderately severe, and severe AP groups (MAP, MSAP, and SAP, respectively) and compared. Results Of the patients, 121 (72.9%) patients had MAP, 40 (24.1%) had MSAP, and five (3%) had SAP. There was no statistically significant difference between the three groups regarding gender and age. The SAP group had significantly higher median values for the length of hospital stay [19 (4-31) days], white blood cell (WBC) count [20.4 x109/L (9.1-23.3 x109/L)], and creatinine (Cre) [1.4 mg/dL (0.7-3.4 mg/dL)] (p<0.001, p=0.003, and p=0.014, respectively). The RDW and albumin values of all the groups were within normal ranges. RAR was higher in the SAP group but did not statistically significantly different between the groups. In the receiver operating characteristic (ROC) analysis of RAR, the area under the curve (AUC) value was determined as 0.75, sensitivity as 80%, specificity as 70.2%, and positive likelihood ratio as 2.1 (p=0.05). Conclusion It is considered that RAR may be a helpful method in determining the course of ABP attacks, but there is a need for studies with a larger series, including all pancreatitis cases.

A nomogram for clinical estimation of acute biliary pancreatitis risk among patients with symptomatic gallstones: A retrospective case-control study.

Background/Purpose: Currently, there are no effective tools to accurately assess acute biliary pancreatitis (ABP) risk in patients with gallstones. This study aimed to develop an ABP risk nomogram in patients with symptomatic gallstones. Methods: We conducted a retrospective nested case-control study and data on 816 conservatively treated patients with symptomatic gallstones admitted to The First Affiliated Hospital of Harbin Medical University between January 6, 2007 and January 22, 2016 were retrospectively collected. We conducted a propensity-score matched (PSM) analysis based on follow-up time in a ratio of 1:4 between ABP group (n=65) and non-ABP group (n=260). These matched patients were randomly divided into study cohort (n=229) and validation cohort (n=96) according to a ratio of 7:3. In the study cohort, independent risk factors for ABP occurrence identified using Cox regression were included in nomogram. Nomogram performance and discrimination were assessed using the concordance index (C-index), area under the curve (AUC), calibration curve, decision curve analysis (DCA) and clinical impact curve (CIC). The model was also validated in the validation cohort. Results: Nomogram was based on 7 independent risk factors: age, diabetes history, gallbladder wall thickness, gallstone diameter, coexisting common bile duct (CBD) stones, direct bilirubin (DBIL), and white blood cell count (WBC). The C-index of nomogram was 0.888, and the 10-year AUCs of nomogram was 0.955. In the validation cohort, nomogram still had good discrimination (C-index, 0.857; 10-year AUC, 0.814). The calibration curve showed good homogeneity between the prediction by nomogram and the actual observation. DCA and CIC demonstrated that nomogram was clinically useful. Conclusions: The ABP risk nomogram incorporating 7 features is useful to predict ABP risk in symptomatic gallstone patients.

Acute Biliary Pancreatitis Management during the Coronavirus Disease 2019 Pandemic.

(1) Objective: We aimed to analyze and describe the management of acute biliary pancreatitis (ABP) during the coronavirus disease 2019 (COVID-19) pandemic. (2) Methods: This was a retrospective cohort study among patients with ABP during a control period (16 March 2019 to 15 March 2020; period 1) and a COVID-19 period (16 March 2020 to 15 March 2021; period 2). (3) Results: We included 89 patients with ABP, being 58 in period 1 and 31 in period 2. The mean patient age was 62.75 ± 16.59 years, and 51 (57.3%) patients were women. The Quick Sequential Organ Failure Assessment score for sepsis and World Society of Emergency Surgery Sepsis Severity Score were significantly higher among patients in period 2. Twenty-two patients (37.9%) in period 1 and six (19.3%) in period 2 underwent cholecystectomy. There were no significant differences in surgical interventions between the two periods. The hospital mortality rate was 3.4 and 19.3% in period 1 and period 2, respectively. Mortality was significantly higher in period 2. Conclusion: During the COVID-19 pandemic, we observed a significant reduction in the number of patients with ABP but increased severity and mortality. Multicenter studies with more patients are needed to obtain additional evidence regarding ABP management during the COVID-19 pandemic.

Abscess of ligamentum teres hepatis post-endoscopic retrograde cholangiopancreatography: A case report and a literature review.

Abscess of the ligamentum teres hepatis has been described in the medical literature as an extremely rare clinical entity, which often presents a diagnostic dilemma. A 68-year-old man was hospitalized for upper abdominal pain and obstructive jaundice. The patient presented with low-grade intermittent fever. Laboratory investigations showed a white blood cell count of 32.38 × 109/L, a C-reactive protein level of 247.86 mg/L, abnormal liver enzyme and bilirubin levels, and elevated serum levels of amylase and lipase. He was first diagnosed with acute biliary pancreatitis. A computational tomography scan and magnetic resonance cholangiopancreatography revealed obstructive choledocholithiasis and cholecystolithiasis. The patient received preoperative antibiotics and symptomatic treatments for 5 days, followed by endoscopic retrograde cholangiopancreatography and a subsequent duodenal papilla incision to extract pigment and cholesterol gallstones. The patient recovered and was discharged on the fifth day after surgery. However, 10 days later, the patient was readmitted for the recurrence of acute calculous cholecystitis. Laboratory tests showed increases in total and direct bilirubin, γ-glutamyltransferase, and alkaline phosphatase, but not inflammatory parameters. After the patient's nutritional status improved on the 11th day after admission, a laparoscopic cholecystectomy was performed. Intraoperative exploration revealed extensive abdominal adhesions; a thickened edematous gallbladder wall; and an unexpected abscess of the ligamentum teres hepatis. Pus aspiration was performed laparoscopically after laparoscopic cholecystectomy, and to ensure elimination of the abscess, ultrasound-guided pus aspiration was also performed 1 week later. Fortunately, the patient made an uneventful recovery and was discharged with a drain tube on the 16th day after surgery. Doppler ultrasound indicated that the abscess had completely disappeared 2 weeks after discharge. This case highlights an unusual presentation of a ligamentum teres hepatis abscess caused by obstructive cholangitis but that appeared after the choledocholithiasis was resolved. However, the mechanism of abscess formation remained uncertain.

[The role of polymorphic variants rs11546155 and rs6119534 of the GGT7 gene and risk factors in the development of acute pancreatitis].

Glutathione is an antioxidant with powerful restorative and detoxifying properties, a progressive decrease in its reserves in erythrocytes and pancreas observed in pancreatic necrosis indicates a lack of functioning of the system for maintaining the level of glutathione in cells and the use of its endogenous reserve. The study of the role of glutathione metabolism enzyme genes in the risk of acute pancreatitis in this regard is especially relevant. The aim of the study was to evaluate the joint contribution of the rs11546155 and rs6119534 polymorphic loci of the GGT7 gene and some risk factors to the development of acute pancreatitis (AP). Material and methods. Molecular genetic analysis of DNA samples of 506 unrelated patients with acute pancreatitis and 524 unrelated individuals of Russian nationality without gastrointestinal diseases, isolated by the standard method of phenol-chloroform extraction, was carried out. The average age of patients was 48.9±13.1 years, healthy persons - 47.8±12.1 years. The diagnosis was established using Clinical guidelines developed by the working group of the Russian Society of Surgeons. All patients signed informed consent to participate in the study. Genotyping was performed using iPLEX technology by time-of-flight mass spectrometry. Associations of gene alleles and genotypes with the risk of acute pancreatitis were assessed by the χ2 criterion and the odds ratio with 95% confidence intervals. Statistical analysis was performed using the SNPStats and Statistica 10.0 programs (Stat-Soft, USA). Results. We have identified an association of the C/T (rs6119534) GGT7 genotype with an increased risk of AP, both in men and women. When analyzing the effect of polymorphic loci on the development of the polymorphic locus rs6119534 of the GGT7 C>T gene with an increased risk of developing acute alcoholic (AAlcP) and biliary pancreatitis (ABP), it was found that the C/T rs6119534 genotype of the GGT7 gene was more common both among patients with AAlcP and ABP, and the G/G GGT7 genotype (rs11546155) was found only among ABP patients. An analysis of the combined influence of polymorphic loci and environmental factors showed that the frequency of drinking alcohol more than 2 times a week and eating fat more than 89 grams per day increased the risk AAlcP in carriers of C/T-T/T rs6119534 of the GGT7 gene. As for ABP, non-smoking carriers of the G/A-A/A GGT7 (rs11546155) genotypes had a reduced risk of the disease, while the consumption of fats over 89 g/day and fresh vegetables and fruits below 27 g/day increased the risk in carriers of genotypes C/T-T/T and C/T rs6119534 of the GGT7 gene, respectively. Conclusion. Polymorphic loci rs6119534 and rs11546155 of the GGT7 gene, when exposed to certain risk factors, increase the risk of acute pancreatitis.
