RESUMEN
Background: Gastrointestinal bleeding (GIB) is common in left ventricular assist devices (LVADs) patients, but the optimal screening approach before LVAD implantation is still unclear. The aim of the study was to describe our experience with pre- and post-LVAD implantation endoscopic screening and subsequent GI bleeding in this cohort. Methods: A retrospective review was conducted among all patients who underwent LVAD implantation at Saint Luke's Hospital, between 2010 and 2020. The data were reviewed to determine the yield and safety of endoscopic procedures performed within 1 month before LVAD placement and the incidence of GIB within 1 year after implantation. Results: A total of 167 LVAD patients met the inclusion criteria, and 23 underwent pre-implantation endoscopic evaluation. Angiodysplasia had a significantly higher odds ratio (OR) of 9.41 (95% confidence interval (CI): 2.01 - 44.09) in post-LVAD endoscopy, while there was no significant difference in bleeding from other sources such as peptic ulcer disease or diverticular bleeding. There was no difference in the incidence of GIB in patients who underwent endoscopic evaluation pre-LVAD compared to post-LVAD GIB (32.6% vs. 39.1%, P = 0.64). Endoscopy was well-tolerated in this cohort, and argon plasma coagulation was the most commonly used intervention to achieve hemostasis. Conclusions: According to our results, we recommend against routine pre-LVAD endoscopic screening. Instead, we suggest an individualized approach, where decisions are made on a case-by-case basis.
RESUMEN
Background: There are conflicting data on the frequency and variability of endoscopic retrograde cholangiopancreatography (ERCP) outcomes in patients with cirrhosis. Our aim was to systematically review the literature on the incidence of post-ERCP adverse events in cirrhotic patients and to examine the differences across continents. Methods: We searched PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases to identify studies reporting adverse events after ERCP in patients with cirrhosis from conception to September 30, 2022. The random effects model was used to calculate odds ratios (ORs), mean differences (MDs), and confidence intervals (CIs). A P value < 0.05 was considered statistically significant. Heterogeneity was assessed using the Cochrane Q-statistic (I2). Results: Twenty-one studies that included 2,576 cirrhotic patients and 3,729 individual ERCPs were analyzed. The pooled overall rate of adverse events after ERCP in patients with cirrhosis was 16.98% (95% CI: 13.06-21.29%, P < 0.001, I2 = 86.55%). ERCPs performed in Asia had the highest ERCP adverse events with an overall complication rate of 19.90%, while the lowest overall adverse events were in North America at 13.04%. The pooled post-ERCP bleeding, pancreatitis, cholangitis and perforation were 5.10% (95% CI: 3.33-7.19%, P < 0.001, I2 = 76.79%), 3.21% (95% CI: 2.20-5.36%, P = 0.03, I2 = 42.25%), 3.02% (95% CI: 1.19-5.52%, P < 0.001, I2 = 87.11%), and 0.12% (95% CI: 0.00 - 0.45, P = 0.26, I2 = 15.76%), respectively. The pooled post-ERCP mortality rate was 0.22% (95% CI: 0.00-0.85%, P = 0.01, I2 = 51.86%). Conclusions: This meta-analysis shows that the overall complication rates after ERCP, bleeding, pancreatitis, and cholangitis are high in patients with cirrhosis. Because cirrhotic patients are more likely to have post-ERCP complications, with significant cross-continent variations, the risks and benefits of ERCP in this patient population should be carefully considered.
RESUMEN
BACKGROUND: Survey studies have found an increased prevalence of migraine in patients with inï¬ammatory bowel disease (IBD). However, the clinical characteristics of migraines in this population are unknown. We conducted a retrospective medical record review study to characterize migraines in the IBD population. METHODS: Six hundred seventy-five migraine patients (280 with IBD, 395 without IBD) who were evaluated at Mayo Clinic Rochester, Mayo Clinic Arizona, or Mayo Clinic Florida between July 2009 and March 2021 were included. Patients with ICD codes for migraine and either Crohn's disease (CD) or ulcerative colitis (UC) were selected. Electronic health care records were reviewed. Patients conï¬rmed to have IBD and migraine were included. Demographic, IBD, and migraine characteristics were collected. Statistical analysis was completed using SAS. RESULTS: Patients with IBD were less often male (8.6% vs 21.3%, P < .001) and had a higher Charlson Comorbidity Index (>2: 24.6% vs 15.7%, P = .003); 54.6% had CD and 39.3% had UC. Patients with IBD had migraine with aura and without aura more frequently ( OR 2.20, P < .001 and OR 2.79, P < .001, respectively) than non-IBD patients. Additionally, those with IBD less commonly had chronic migraine (OR 0.23, P < .001) and less commonly had chronic migraine or treatment for migraine (ORs 0.23-0.55, P ≤ .002). CONCLUSIONS: Migraine with and without aura have increased prevalence in IBD patients. Further study of this topic will be helpful to clarify the prevalence of migraine, establish this population's response to treatment, and better understand the reason(s) for a low rate of treatment.

BACKGROUND: Incidentalomas, defined as incidental findings on imaging, are a growing concern. Our aim was to determine the impact and outcomes of extrahepatic incidentalomas on liver transplantation. METHODS: Patients at a large liver transplant center, who had an initial MRI for hepatocellular carcinoma screening between January 2004 and March 2020 were identified. Clinical data were collected retrospectively. Survival analysis, utilizing Kaplan Meier estimates and Cox proportional hazards regression analysis, was utilized to determine factors associated with liver transplantation. RESULTS: 720 patients were included. NASH (24.9%), HCV (22.1%) and alcohol (20.6%) were the most common causes of cirrhosis. 79.7% of patients had an extrahepatic incidentaloma. Older age and having received a liver transplant by the end of the study were associated with an incidentaloma. MELD was not associated with the presence of an incidentaloma. On univariate Cox proportional hazards regression, male sex, history of moderate alcohol use, smoking history, MELD, and incidentalomas were predictors of liver transplantation. On multivariate analysis, only MELD and the presence of an incidentaloma were found to be significant. Discovery of an incidentaloma was associated with a 30% increase in the risk of liver transplantation. Median time to transplantation did not differ based on the presence on an incidentaloma. Patients with cirrhosis from alcohol or HCV had a significantly shorter median time to transplantation than those with NASH. Renal and pancreatic lesions comprised 91% of all incidentalomas. CONCLUSIONS: In this single-center retrospective study, extrahepatic incidentalomas were common in patients with cirrhosis. The finding of an incidentaloma was associated with a higher risk of liver transplantation despite a similar median time to transplantation if no incidentaloma was discovered.

BACKGROUND: Sclerosing mesenteritis is a rare condition characterized by chronic inflammation and fibrotic changes of the mesentery. AIMS: To determine the long-term management and outcomes of patients with sclerosing mesenteritis. METHODS: Patients with biopsy-proven sclerosing mesenteritis at the Mayo Clinic between January 2006 and December 2016 were identified. Clinical data were collected retrospectively. RESULTS: One hundred and three patients were identified, median age 68.0 years (range 35.0-85.3). Most patients were symptomatic (87.4%) at presentation. Patients received no treatment (52.4%), medical therapy (42.7%) or surgery (4.9%) on initial diagnosis. The most common initial regimens were prednisone plus tamoxifen (41.9%), prednisone alone (23.3%), and prednisone plus colchicine (11.6%) with 55.6%, 57.2%, and 60% of patients improving, respectively, p = 0.85 for a difference in response rates. At least half of the patients responded to prednisone plus tamoxifen, prednisone plus colchicine, or prednisone alone at 6.0, 7.2, and 8.4 months, respectively. At a median follow-up of 45.6 months (95% CI 24.1-69.7), 65.4% of patients were receiving medical therapy. Of those receiving tamoxifen-based, steroid-based, or steroid-sparing regimens, 100%, 87.5%, and 77.8% had improved by their last follow-up appointment respectively, p = 0.15. CONCLUSION: Prednisone plus colchicine has a similar efficacy to prednisone plus tamoxifen for the initial and long-term treatment of sclerosing mesenteritis. The majority of patients were initiated on medical therapy over the long term with most reporting symptomatic improvement within a year. Death from SM was rare.

OBJECTIVES: Patients with microscopic colitis may have subtle macroscopic findings on colonoscopy such as erythema, edema, or altered vascular pattern; however, radiographic abnormalities on cross-sectional imaging have not been investigated. We aimed at identifying the abdominopelvic radiographic abnormalities in patients with microscopic colitis, as well as possible correlation with endoscopic findings and the need for extended duration of treatment. MATERIALS AND METHODS: This was a retrospective study of patients with biopsy-proven microscopic colitis at two tertiary centers between 1 January 2010 and 30 April 2020. Patients underwent computed tomography scan or magnetic resonance imaging within 30 days of a diagnostic flexible sigmoidoscopy or colonoscopy. Patients with colon ischemia and other causes of colitis were excluded. Radiographic abnormalities from imaging reports included bowel wall thickening, mucosal hyperenhancement and mesenteric fat stranding. Univariate and multivariable logistic regression models were used to identify predictors of radiographic abnormalities. RESULTS: 498 patients with microscopic colitis underwent abdominopelvic cross-sectional imaging within 30 days of flexible sigmoidoscopy/colonoscopy. Lymphocytic colitis was diagnosed in 54.6% of patients, and collagenous colitis in 45.4%. Endoscopic and radiographic abnormalities were identified in 16.1% and 12.4% of patients, respectively. Radiographic abnormalities were associated with the need for budesonide therapy (p = .029) and budesonide therapy long-term (p = .0028). Budesonide therapy long-term (p = .047) was associated with radiographic abnormalities in multivariate analysis. CONCLUSIONS: Radiographic abnormalities may be present on abdominopelvic cross-sectional imaging in a minority of patients with biopsy-proven microscopic colitis, suggesting cross-sectional imaging has low clinical value in the evaluation and treatment of this disease.

INTRODUCTION AND OBJECTIVES: The goal of this study was to assess lifestyle habits and physician counseling of patients with hereditary hemochromatosis (HH), and determine the prevalence of direct-to-consumer (DTC) genetic testing. MATERIALS AND METHODS: A 52-question survey was created to collect information on lifestyle habits and physician counseling among patients with HH, and the use of DTC genetic testing of patients referred to a clinic for evaluation of HH. A multivariate logistic regression model was applied to identify predictors of DTC genetic testing use. RESULTS: The survey was e-mailed to 379 patients, of which 101 responded (26.6%). Among patients with HH, 37% reported alcohol use more than once weekly and 50% reported red meat consumption. The use of a vitamin C supplement was reported by 38.9% of participants. Among patients with living children and siblings, physicians failed to recommend HH screening 15.3% and 21.2% of the time respectively. Thirty-one patients reported DTC genetic testing, of which 46.7% (14/31) reported their DTC genetic test screened for HH. Six (19%) of those patients were prompted to see a specialist in HH based on the results. CONCLUSIONS: Among patients with HH, lifestyle habits that may impact iron stores are common, but not all receive appropriate counseling. Direct-to-consumer genetic testing is common, and physicians should be aware of its limitations when patients seek further evaluation for HH based on their test results.

BACKGROUND: Magnetic resonance elastography (MRE) is a non-invasive test used to assess liver stiffness and fibrosis in chronic liver disease, which includes systemic iron overload. However, iron deposition by itself is associated with technical failure of MRE of the liver which necessitates the use of invasive liver biopsy as an alternative monitoring method for these patients. T2*-weighted magnetic resonance imaging (T2*) is a reliable modality to asses for hepatic as well as total body iron overload. Therefore, we aimed to determine a cutoff value on the T2* reading at which MRE would no longer provide accurate stiffness measurements in patients with iron overload. METHODS: Ninety-five patients with iron overload who underwent MRE at our institution, between 2010 and 2017 were reviewed retrospectively. We compared T2* values between patients with adequate elastography (N=63) versus those with non-diagnostic elastography (N=32). We additionally examined the ability of T2* to predict the likelihood of non-diagnostic elastography by estimating area under the ROC curve (AUC). RESULTS: T2* was significantly different between patients with and without an adequate elastography (P<0.0001) and predicted occurrence of non-diagnostic elastography with an AUC of 0.95. All patients with a non-diagnostic elastography had a T2* value below 20 milliseconds (ms), and correspondingly 55% of the patients with a T2* value below 20 ms had a non-diagnostic elastography. The subgroups of patients with a T2* value ≤10, ≤8, and ≤6 ms, had a higher likelihood of non-diagnostic elastography (87%, 92%, and 95%, respectively). CONCLUSIONS: T2* can be used to accurately predict which patients are most likely to have a non-diagnostic elastography reading. T2* of 20 ms or lower reflects a higher likelihood of non-diagnostic elastography.
RESUMEN
Early detection improves hepatocellular carcinoma (HCC) outcomes, but better noninvasive surveillance tools are needed. We aimed to identify and validate methylated DNA markers (MDMs) for HCC detection. Reduced representation bisulfite sequencing was performed on DNA extracted from 18 HCC and 35 control tissues. Candidate MDMs were confirmed by quantitative methylation-specific PCR in DNA from independent tissues (74 HCC, 29 controls). A phase I plasma pilot incorporated quantitative allele-specific real-time target and signal amplification assays on independent plasma-extracted DNA from 21 HCC cases and 30 controls with cirrhosis. A phase II plasma study was then performed in 95 HCC cases, 51 controls with cirrhosis, and 98 healthy controls using target enrichment long-probe quantitative amplified signal (TELQAS) assays. Recursive partitioning identified best MDM combinations. The entire MDM panel was statistically cross-validated by randomly splitting the data 2:1 for training and testing. Random forest (rForest) regression models performed on the training set predicted disease status in the testing set; median areas under the receiver operating characteristics curve (AUCs; and 95% confidence interval [CI]) were reported after 500 iterations. In phase II, a six-marker MDM panel (homeobox A1 [HOXA1], empty spiracles homeobox 1 [EMX1], AK055957, endothelin-converting enzyme 1 [ECE1], phosphofructokinase [PFKP], and C-type lectin domain containing 11A [CLEC11A]) normalized by beta-1,3-galactosyltransferase 6 (B3GALT6) level yielded a best-fit AUC of 0.96 (95% CI, 0.93-0.99) with HCC sensitivity of 95% (88%-98%) at specificity of 92% (86%-96%). The panel detected 3 of 4 (75%) stage 0, 39 of 42 (93%) stage A, 13 of 14 (93%) stage B, 28 of 28 (100%) stage C, and 7 of 7 (100%) stage D HCCs. The AUC value for alpha-fetoprotein (AFP) was 0.80 (0.74-0.87) compared to 0.94 (0.9-0.97) for the cross-validated MDM panel (P < 0.0001). Conclusion: MDMs identified in this study proved to accurately detect HCC by plasma testing. Further optimization and clinical testing of this promising approach are indicated.

Hepatic portal venous gas (HPVG) is a rare radiological sign that usually signifies an acute intra-abdominal process, most commonly bowel ischemia and sepsis. Few reports described an association with underlying gastric pathologies. We report a 60-year-old patient who presented with melena and chills and was discovered to have a gastric ulcer that appeared to have penetrated into a mesenteric varix. This, in turn, likely caused development of HPVG associated with fungemia. Treatment with a proton pump inhibitor and bowel rest was sufficient to resolve symptoms and the HPVG.
RESUMEN
Xanthogranulomatous pyelonephritis (XGP) is a rare histological subset of pyelonephritis characterized by being a chronic destructive granulomatous inflammation of the renal parenchyma. XGP is classified according to the extent of disease into two entities: within the renal cortex (focal or segmental XGP) or diffuse spread with pelvic communication (diffuse XGP). Although rare, XGP can have fatal complications including perinephric, psoas abscess, nephro-cutaneous fistula and reno-colic fistula. Only few studies have reported XGP complicated with psaos abcess and reno-colic fistula. Our aim is to add to the literature and share our experience with a case of extensive XGP eroding into the psoas muscle and ascending colon leading to severe sepsis that was successfully managed. We report a 56-year-old woman who was found to have XGP complicated by psoas abscess and reno-colic fistula managed by antibiotics, nephrostomy, and subsequent nephrectomy and partial colectomy.
RESUMEN
UNLABELLED: Whether aspirin use is protective against cholangiocarcinoma (CCA) remains unclear. We determined the association between aspirin use and other risk factors for each CCA subtype individually. In a hospital-based case-control study, 2395 CCA cases (1169 intrahepatic, 995 perihilar, and 231 distal) seen at the Mayo Clinic, Rochester, MN, from 2000 through 2014 were enrolled. Controls selected from the Mayo Clinic Biobank were matched two to one with cases by age, sex, race, and residence (n = 4769). Associations between aspirin use, other risk factors, and CCA risk were determined. Aspirin was used by 591 (24.7%) CCA cases and 2129 (44.6%) controls. There was a significant inverse association of aspirin use with all CCA subtypes, with adjusted odds ratios (AORs) of 0.35 (95% confidence interval [CI], 0.29-0.42), 0.34 (95% CI 0.27-0.42), and 0.29 (95% CI 0.19-0.44) for intrahepatic, perihilar, and distal CCA, respectively (P < 0.001 for all). Primary sclerosing cholangitis was more strongly associated with perihilar (AOR = 453, 95% CI 104-999) than intrahepatic (AOR = 93.4, 95% CI 27.1-322) or distal (AOR = 34.0, 95% CI 3.6-323) CCA, whereas diabetes was more associated with distal (AOR = 4.2, 95% CI 2.5-7.0) than perihilar (AOR = 2.9, 95% CI 2.2-3.8) or intrahepatic (AOR = 2.5, 95% CI 2.0-3.2) CCA. Cirrhosis not related to primary sclerosing cholangitis was associated with both intrahepatic and perihilar CCA, with similar AORs of 14. Isolated inflammatory bowel disease without primary sclerosing cholangitis was not associated with any CCA subtype. CONCLUSIONS: Aspirin use was significantly associated with a 2.7-fold to 3.6-fold decreased risk for the three CCA subtypes; our study demonstrates that individual risk factors confer risk of different CCA subtypes to different extents.
