Abstract
The sphincter of Oddi is a delicate neuromuscular structure located at the junction of the biliary-pancreatic system and the duodenum. Sphincter of Oddi Dysfunction (SOD) can result in various clinical manifestations, including biliary-type pain and recurrent idiopathic pancreatitis. The management of SOD has been challenging. With the publication of the landmark Evaluating Predictors and Interventions in Sphincter of Oddi Dysfunction (EPISOD) trial and the Rome IV consensus, our clinical practice in the treatment of SOD has changed significantly in recent years. Currently, the management of type II SOD remains controversial and there is a lack of non-invasive therapy options, particularly for patients not responding to endoscopic treatment. In this mini review, we aimed to discuss the current knowledge on the treatment of biliary SOD.

Risk stratification of gallbladder masses by machine learning-based ultrasound radiomics models: a prospective and multi-institutional study. Eur Radiol 2023; 33:8899-8911. [PMID: 37470825 DOI: 10.1007/s00330-023-09891-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 03/23/2023] [Accepted: 04/26/2023] [Indexed: 07/21/2023]
Abstract
OBJECTIVE This study aimed to evaluate the diagnostic performance of machine learning (ML)-based ultrasound (US) radiomics models for risk stratification of gallbladder (GB) masses. METHODS We prospectively examined 640 pathologically confirmed GB masses obtained from 640 patients between August 2019 and October 2022 at four institutions. Radiomics features were extracted from grayscale US images and germane features were selected. Subsequently, 11 ML algorithms were separately used with the selected features to construct optimum US radiomics models for risk stratification of the GB masses. Furthermore, we compared the diagnostic performance of these models with the conventional US and contrast-enhanced US (CEUS) models. RESULTS The optimal XGBoost-based US radiomics model for discriminating neoplastic from non-neoplastic GB lesions showed higher diagnostic performance in terms of areas under the curves (AUCs) than the conventional US model (0.822-0.853 vs. 0.642-0.706, p < 0.05) and potentially decreased unnecessary cholecystectomy rate in a speculative comparison with performing cholecystectomy for lesions sized over 10 mm (2.7-13.8% vs. 53.6-64.9%, p < 0.05) in the validation and test sets. The AUCs of the XGBoost-based US radiomics model for discriminating carcinomas from benign GB lesions were higher than the conventional US model (0.904-0.979 vs. 0.706-0.766, p < 0.05). The XGBoost-US radiomics model performed better than the CEUS model in discriminating GB carcinomas (AUC: 0.995 vs. 0.902, p = 0.011). CONCLUSIONS The proposed ML-based US radiomics models possess the potential capacity for risk stratification of GB masses and may reduce the unnecessary cholecystectomy rate and use of CEUS. CLINICAL RELEVANCE STATEMENT The machine learning-based ultrasound radiomics models have potential for risk stratification of gallbladder masses and may potentially reduce unnecessary cholecystectomies. KEY POINTS • The XGBoost-based US radiomics models are useful for the risk stratification of GB masses. • The XGBoost-based US radiomics model is superior to the conventional US model for discriminating neoplastic from non-neoplastic GB lesions and may potentially decrease unnecessary cholecystectomy rate for lesions sized over 10 mm in comparison with the current consensus guideline. • The XGBoost-based US radiomics model could overmatch CEUS model in discriminating GB carcinomas from benign GB lesions.

Recurrence of common bile duct stones after choledocholithotomy in elderly patients: risk factor analysis and clinical prediction model development. Front Med (Lausanne) 2023; 10:1239902. [PMID: 37937139 PMCID: PMC10626465 DOI: 10.3389/fmed.2023.1239902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 10/11/2023] [Indexed: 11/09/2023] Open
Abstract
Background The reasons for the recurrence of common bile duct stones (CBDS) in elderly patients after choledocholithotomy are still unclear. This study aims to establish a prediction model for CBDS recurrence by identifying risk factors. Methods We conducted a retrospective analysis of 1804 elderly patients aged 65 years and above who were diagnosed to have CBDS and were admitted to Nanjing First Hospital between January 1, 2010, and January 1, 2021. According to inclusion and exclusion criteria, 706 patients were selected for the final analysis. The patients were assigned to two groups according to the presence or absence of CBDS recurrence, and their clinical data were then statistically analyzed. Subsequently, a prediction model and nomogram were developed, evaluating effectiveness using the concordance index (C-index). Results Of the 706 elderly patients, 62 patients experienced CBDS recurrence after surgery, resulting in a recurrence rate of 8.8%. The multivariate Cox analysis showed that prior history of cholecystectomy (hazard ratio [HR] = 1.931, 95% confidence interval [CI]: 1.051-3.547, p = 0.034), white blood cell (WBC) count ≥11.0 × 109/L (HR = 2.923, 95% CI: 1.723-4.957, p < 0.001), preoperative total bilirubin (TBIL) level ≥ 36.5 mmol/L (HR = 2.172, 95% CI: 1.296-3.639, p = 0.003), number of stones ≥2 (HR = 2.093, 95% CI: 1.592-5.294, p = 0.001), maximum stone diameter ≥ 0.85 cm (HR = 1.940, 95% CI: 1.090-3.452, p = 0.024), and T-tube drainage (HR = 2.718, 95% CI: 1.230-6.010, p = 0.013) were independent risk factors of CBDS recurrence in elderly patients after choledocholithotomy. A postoperative CBDS recurrence prediction model was constructed with a C-index value of 0.758 (95% CI: 0.698-0.818) and internal validation value of 0.758 (95% CI: 0.641-0.875). Conclusion A history of cholecystectomy, WBC count ≥11.0 × 109/L, preoperative TBIL level ≥ 36.5 mmol/L, number of stones ≥2, maximum stone diameter ≥ 0.85 cm, and T-tube drainage are the independent risk factors of CBDS recurrence after choledocholithotomy in elderly patients. Our developed prediction model for CBDS recurrence has good predictive ability and can help predict the prognosis of patients with CBDS.

Abstract
BACKGROUND Post-cholecystectomy syndrome (PCS) refers to persistent or new abdominal symptoms after cholecystectomy. As there are very few reports on PCS in pediatric patients, we aimed to examine whether it was a frequent finding and which symptoms the affected children experienced. METHOD This is a retrospective cross sectional study of pediatric patients, who underwent cholecystectomy during 2003-2019 at Oslo University Hospital. The PedsQL™ gastrointestinal symptoms scale questionnaire and a self-designed questionnaire exploring satisfaction after surgery and current medical conditions were mailed to all eligible patients. Patient/parental consent and approval from the local data protection officer (19/09054) were obtained. RESULTS Questionnaires were sent to 82 patients of whom 44 (54%) answered. There were no significant demographic differences between the responders and the non responders. We identified 16 (36.7%) patients to have PCS. The most common symptoms were diarrhea (25%), bloating (16%), and heartburn/reflux (16%). Overweight was more common in patients with PCS (31%) than in patients without PCS (4%) (p = 0.014). Altogether 34/44 (77.3%) patients were satisfied with the result of the cholecystectomy; 92,6% of patients without PCS and 56.6% of those with PCS (p = 0.012). CONCLUSION PCS is not uncommon in pediatric patients, and they report a wide range of gastrointestinal symptoms. We identified overweight as a potential risk factor for developing PCS. Nonetheless, most patients got total relief of abdominal pain and were satisfied with outcome after cholecystectomy. LEVEL OF EVIDENCE Level 3.

Abstract
PURPOSE Chronic, abdominal pain remains a problem in a subset of patients after cholecystectomy. The cause is often obscure but central sensitization may be an important component and could theoretically be mediated by spinal PGE2, which is regulated by several cytokines. The aim of the study was to examine cerebrospinal fluid (CSF) of participants with post cholecystectomy syndrome and healthy volunteers for signs of PGE2 and cytokine mediated central sensitization. PATIENTS AND METHODS In phase 1 of the study, 83 subjects were included for DNA analysis, eight of these subjects with post cholecystectomy syndrome. We examined the SNPs rs5275, rs16944 and rs1800795 from the Cox-2, IL-1β and IL-6 genes respectively. In phase 2 of the study, we examined concentrations of PGE2-metabolite (PGEM), IL-1β and IL-6 in CSF and plasma from 6 patients with post cholecystectomy syndrome and visceral hyperalgesia and 11 pain free volunteers. RESULTS We found a significant difference in distribution of the rs5275 SNP of the Cox-2 enzyme (CT-genotype=88% in pain group, 45% in pain free group, TT-genotype=0 in pain group, 41% in pain free group, p=0.05) but not in the other SNPs. PGEM, but not IL-6, was significantly elevated in CSF of the pain group (3.6 pg/mL, sd=1.9 vs 2.1 pg/mL, p=0.03), IL-1β was undetectable. CONCLUSION We found elevated PGEM levels in CSF of patients with post cholecystectomy syndrome and visceral hyperalgesia, suggesting a central, possibly inflammatory component to the pain, and overrepresentation of the CT-genotype in the rs5275 SNP in the Cox2 gene, suggesting overexpression of Cox2 as a possible cause for elevated PGEM levels.

Abstract
Studies have suggested that adults with gallbladder disease have increased risk of type 2 diabetes. This prospective cohort study assessed the risk of type 2 diabetes in postmenopausal women with gallbladder disease. Data from women enrolled in the Women's Health Initiative from 1993 to 2005, aged 50-79 years (mean = 63.2; standard deviation, 7.2), were analyzed. Cox proportional hazards regression models were used to estimate the risk of type 2 diabetes associated with gallbladder disease. There were 8,896 new cases of type 2 diabetes after 1,025,486 person-years of follow-up. Gallbladder disease was significantly associated with type 2 diabetes (hazard ratio = 1.52; 95% confidence interval (CI): 1.38,1.67). The observed risk of type 2 diabetes in women with both gallbladder disease and central obesity was 37% higher than expected (relative excess risk due to interaction = 0.37, 95% CI: 0.11,0.63) on the additive scale. The hazard ratios for type 2 diabetes associated with gallbladder disease were 1.25 (95% CI: 1.19,1.32) and 1.48 (95% CI: 1.34,1.63) in women with and without central obesity, respectively, on the multiplicative scale. Results of this study support further studies to determine whether interventions in older women with gallbladder disease would reduce type 2 diabetes risk, especially among those with central obesity. Future research should examine the pathophysiological basis of the association between gallbladder disease and type 2 diabetes.

Evaluating the efficacy of endoscopic sphincterotomy on biliary-type sphincter of Oddi dysfunction: A retrospective clinical trial. World J Clin Cases 2021; 9:9835-9846. [PMID: 34877322 PMCID: PMC8610902 DOI: 10.12998/wjcc.v9.i32.9835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 07/18/2021] [Accepted: 09/01/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Although endoscopic sphincterotomy (EST) has a positive therapeutic effect on biliary-type sphincter of Oddi dysfunction (SOD), some patients still have little relief after EST, which implies that other functional abdominal pain may also be present with biliary-type SOD and interfere with the diagnosis and treatment of it.
AIM To retrospectively assess EST as a treatment for biliary-type SOD and analyze the importance of functional gastrointestinal disorder (FGID) in guiding endoscopic treatment of SOD.
METHODS Clinical data of 79 patients with biliary-type SOD (type I and type II) treated with EST at Affiliated Hospital of Guizhou Medical University from January 2014 to January 2019 were retrospectively collected to evaluate the clinical therapeutic effect of EST. The significance of relationship between FGID and biliary-type SOD was analyzed.
RESULTS Seventy-nine patients with biliary-type SOD received EST, including 29 type 1 patients and 50 type 2 patients. The verbal rating scale-5 (VRS-5) scores before EST were all 3 or 4 points, and the scores decreased after EST; the difference was statistically significant (P < 0.05). After EST, the serum indexes of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and total bilirubin in biliary-type SOD were significantly lower than before (P < 0.05). After EST, 67 (84.8%) and 8 (10.1%) of the 79 patients with biliary-type SOD had obviously effective (VRS-5 = 0 points) and effective treatment (VRS-5 = 1-2 points), with an overall effectiveness rate of 94.9% (75/79). There was no difference in VRS-5 scores between biliary-type SOD patients with or without FGID before EST (P > 0.05). Of 12 biliary-type SOD (with FGID) patients, 11 had abdominal pain after EST; of 67 biliary-type SOD (without FGID) patients, 0 had abdominal pain after EST. The difference was statistically significant (P <0.05). The 11 biliary-type SOD (with FGID) patients with recurrence of symptoms, the recurrence time was about half a year after the EST, and the symptoms were significantly relieved after regular medical treatment. There were 4 cases of post-endoscopic retrograde cholangiopancreatography pancreatitis (5.1%), and no cholangitis, bleeding or perforation occurred. Patients were followed up for 1 year to 5 years after EST, with an average follow-up time of 2.34 years, and there were no long-term adverse events such as sphincter of Oddi restenosis or cholangitis caused by intestinal bile reflux during the follow-up.
CONCLUSION EST is a safe and effective treatment for SOD. For patients with type I and II SOD combined with FGID, single EST or medical treatment has limited efficacy. It is recommended that EST and medicine be combined to improve the cure rate of such patients.

Abstract
Background Laparoscopic cholecystectomy (LC) is regarded as the criterion standard for gallstone therapy, but post-cholecystectomy syndrome (PCS) is a common complication. This study aimed to analyze and identify differences in gut microbiome in PCS patients. Material/Methods This study involved 8 PCS patients (RS1), 8 asymptomatic PCS patients (RS2), and 8 healthy individuals (RS3). Genomic DNA of gut microbiome was extracted and amplified with CTAB method. PCR products were sequenced with Illumina High-Through Sequencing. Sequencing data were analyzed with QIIME software. Effective sequence of bacterial 16S-rRNA gene was clustered into OTUs using UPARSE software. Species annotations were evaluated using Mothur software. QIIME software was used to conduct complexity analysis and calculate UniFrac distances. R software was used to generate PCoA plots. Results Bacterial 16S-rDNA gene sequences showed that the effective species annotative data were more than 97%. According to Ternary plot, Firmicutes and Bacteroidetes had similar abundance and contents among the 3 groups. Contents of Proteobacteria in RS1 were higher compared to RS2 and RS3. Bacterial genomic DNAs samples were clustered together in the same group; however, distances were relative far between different groups. RS1 illustrated significantly higher abundance of Proteobacteria colonies compared to healthy people (p<0.05), and illustrated higher abundance of Verrucomicrobia and lower abundance of Bacteroidetes and Firmicutes, but without significant differences (p>0.05). Conclusions Gut microbiome of PCS patients was dominated by Proteobacteria in feces and contained little Firmicutes and Bacteroidetes. The enhanced abundance of Proteobacteria might be the highly pathogenic risk factor for chronic abdominal pain and diarrhea in PCS patients.

Abstract
Sphincter of Oddi dysfunction (SOD) is a clinical syndrome referring to the loss of normal physiological function of the sphincter of Oddi with upper abdominal pain from the gallbladder and pancreas, postprandial abdominal bloating, elevation of liver or pancreatic enzymes, common bile duct dilation, pancreatitis and so on. SOD is more common in patients after cholecystectomy. Although the established criteria for diagnosing and treating SOD have been applied in clinical practice, its diagnosis and treatment have long been a controversial topic since the best diagnostic and treatment methods are still unconfirmed, partly because of its natural course, disease treatment process, and long-term follow-up outcomes that have not been determined in large controlled studies. This article briefly reviews the latest research of SOD and comprehensively analyzes the current status and existing problems in the diagnosis and treatment of SOD, with an aim to provide appropriate advice for clinicians to diagnose and treat this disease.

Harinstein L, Wu E, Brinker A. Postmarketing cases of eluxadoline-associated pancreatitis in patients with or without a gallbladder. Aliment Pharmacol Ther 2018; 47:809-815. [PMID: 29349789 DOI: 10.1111/apt.14504] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 11/27/2017] [Accepted: 12/16/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Cases of pancreatitis were identified in the eluxadoline clinical development program, reflected in initial product labelling, and the subject of postmarketing reports. AIM To analyse postmarketing cases of eluxadoline-associated pancreatitis. METHODS We retrospectively analysed all US adverse event reports of pancreatitis associated with eluxadoline reported to the FDA Adverse Event Reporting System (FAERS) database from May 27, 2015 through February 15, 2017. RESULTS The analysis included 119 cases of pancreatitis associated with eluxadoline; one resulted in death and 75 in hospitalisation. Sixty-seven cases reported the presence (n = 12) or absence (n = 55) of the patient's gallbladder. The eluxadoline dose received in the 55 cases of patients without gallbladders was 75 mg (n = 43), 100 mg (n = 5), or not reported (n = 7). Of the 119 cases, 37 reported the patient did not abuse alcohol and 82 did not report the alcohol abuse status. The single fatal case occurred in a patient without a gallbladder who received eluxadoline 75 mg and did not abuse alcohol. Forty-seven cases reported development of pancreatitis within the first or second dose of eluxadoline initiation. The median time to onset for the development of pancreatitis (n = 83) was 1 day, ranging from 1 to 56 days of continued use of eluxadoline. CONCLUSION The FAERS cases suggest that patients with or without a gallbladder receiving eluxadoline are at risk for the development of pancreatitis. However, patients without a gallbladder, despite receiving the recommended lower dose of eluxadoline 75 mg and screening for alcohol abuse, appear to be overrepresented among patients who developed eluxadoline-associated pancreatitis.
