A Case of Idiopathic Non-Cirrhotic Portal Hypertension in a Patient With a Left Ventricular Assist Device.

Idiopathic non-cirrhotic portal hypertension is a rare diagnosis caused by an unknown etiology with elevated intrahepatic portal pressures in the absence of underlying liver disease. We present a unique case of a 57-year-old male with a left ventricular assist device and preserved right ventricular function that was found to have an elevated hepatic venous pressure gradient and sequelae of portal hypertension without underlying liver disease. There is limited treatment available as management is primarily aimed toward preventing complications of the disease. This case highlights the need for further investigative research of this disease entity and its pathogenesis.

Racial Disparities in Clinical Presentation and Survival Times Among Young-Onset Colorectal Adenocarcinoma.

BACKGROUND: Recently published data indicate increasing incidence of colorectal adenocarcinoma (CRC) in young-onset (<50 years) patients. AIMS: This study examines racial disparities in presentation and survival times among non-Hispanic Blacks (NHB) and Hispanics compared with non-Hispanic Whites (NHW). METHODS: A retrospective single-center cohort study was conducted from 2004 through 2014 using 96 patient medical charts with a diagnosis of young-onset CRC. Age, gender, primary site, and histological stage at the time of diagnosis were assessed for survival probabilities by racial group over a minimum follow-up period of 5 years. RESULTS: Among subjects with CRC diagnosis before 50 years of age, the majority of subjects were between 40 and 50 years, with CRC presentation occurring among this age group for 51 (79.7%) of NHW, 18 (81.8%) of NHB, and 5 (50.0%) of Hispanics. The majority of all patients presented with advanced stages of CRC (31.3% with stage III and 27.1% with stage IV). NHB exhibited statistically significantly worse survival compared to NHW (adjusted hazard ratio for death = 2.09; 95% confidence interval 1.14-3.84; P = 0.02). A possible trend of worse survival was identified for Hispanics compared to NHW, but this group was low in numbers and results were not statistically significant. CONCLUSION: Disparities between racial groups among young-onset CRC cases were identified in overall survival and reflect growing concern in rising incidence and differentiated care management.

Mirrizi Syndrome and Markedly Elevated Levels of Carbohydrate Antigen 19-9 in the Absence of Malignant Disease.

Elevated carbohydrate antigen 19-9 (CA19-9) beyond 1000 U/L occurs in nonneoplastic conditions which is causing questioning of the use of CA19-9 as a marker for screening. We report a case where a 51-year-old male with Mirrizi Syndrome (MS) presented with markedly increased CA19-9 level (4,618 U/mL). MS is a rare complication characterized by compression of the common bile or hepatic duct caused by an impacted gallstone in the cystic duct or neck of the gallbladder. Biliary epithelial cells secrete CA19-9: it is hypothesized that increased proliferation of such cells caused by inflammation leads to increased secretion. CA19-9 should not be used as a diagnostic tool, but rather for surveillance.

Racial Disparities in Colorectal Carcinoma Incidence, Severity and Survival Times Over 10 Years: A Retrospective Single Center Study.

BACKGROUND: Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in the United States. Although studies have been performed on malignancy behavior in African Americans and Caucasians, scant data are present on other minority racial groups. METHODS: A retrospective single center study was performed where 1,860 patient charts with a diagnosis of CRC from January 1, 2004 to December 31, 2014 were reviewed. Data collected on each patient included age, gender, ethnicity, primary site and histological stage at the time of diagnosis. Survival time over the course of 5 years was documented for patients from January 1, 2004 to December 31, 2009. Comparisons were made amongst different racial groups for the above mentioned factors. RESULTS: Study population consisted of 27.09% African Americans, 65.61% Caucasians, 3.86% Hispanics, 0.54% South Asians, 1.03% Arabs, 0.54% Asians and 0.22% American Indians. Mean age of CRC presentation was found to be significantly different (P < 0.05) between the three largest racial groups: 71 years for Caucasians, 69 years for African Americans, and 61 years for Hispanics. African Americans (27.09%) and Hispanics (28.79%) presented predominantly at stage IV in comparison to other racial groups. Caucasians presented predominantly at stage III (24.84%). The rectum was the most common site of CRC across all racial groups with the exception of Asians, where sigmoid colon was the predominant site (30%). Adenocarcinoma remained the predominant cancer type in all groups. Hispanics had relatively higher incidence rate of carcinoid tumor (12.68%). Survival time analysis showed that Caucasians tend to have better survival probability over 5 years after initial diagnosis as compared to African Americans and Hispanic (P < 0.05). CONCLUSION: There is lack of studies performed on minority racial groups in North America. Our study highlighted some important clinical differences of CRC presentation in different racial groups which are not well studied and can be used to formulate future multi-center studies to assess disease behavior.

Markedly Elevated Liver Enzymes in Choledocholithiasis in the absence of Hepatocellular Disease: Case Series and Literature Review.

Liver enzyme levels are commonly obtained in the evaluation of many conditions. Elevated alanine transaminase and aspartate transaminase have traditionally been considered a "hepatocellular" pattern concerning for ischemic, viral, or toxic hepatitis. Elevations in these levels pose a diagnostic dilemma in patients without a clinical picture consistent with liver disease. On the other hand, elevated alkaline phosphatase historically represents a "cholestatic" pattern concerning for gallbladder and biliary tract disease. Often, patients present with a "mixed" picture of elevation in all 3 liver enzymes, further confounding the clinical scenario. We present 4 cases of women with severe upper abdominal pain and markedly elevated transaminases. Three of the patients had accompanying jaundice. A higher rise in enzyme levels was seen in those who had greater bile duct dilation. All patients saw a rapid decrease in transaminases after biliary decompression, along with a fall in alkaline phosphatase and total bilirubin levels. No evidence of liver disease was found, nor were there any signs of hepatocellular disease on imaging. The patients were ultimately found to have choledocholithiasis on endoscopic retrograde cholangiopancreatography with no hepatocellular disease. Furthermore, our cases show that severe abdominal pain in the setting of elevated liver enzymes is likely associated with biliary disease rather than a primary hepatic process. Recognition of this rare pattern of markedly elevated transaminases in isolated biliary disease can aid in avoiding unnecessary evaluation of primary hepatic disease and invasive surgical interventions such as liver biopsy.

Guideline on the management of anticoagulation and antiplatelet therapy for endoscopic procedures.

This is one of a series of statements discussing the practice of gastrointestinal endoscopy in common clinical situations. It is intended to aid endoscopists in determining the appropriate use of endoscopic procedures in conjunction with anticoagulation and/or antiplatelet therapy. Guidelines for the appropriate practice of endoscopy are based on critical review of the available data and expert consensus. Controlled clinical studies would be beneficial to clarify some aspects of this statement and revision might be necessary as new data appear. Clinical consideration may justify a course of action at variance from these specific recommendations.
