Ectopic Opening of the Bile Duct Into the Duodenal Bulb: Complications of Biliary Drainage.

Ectopic opening of the common bile duct is a rare anatomic variant that is associated with increased risk of complications such as cholangitis, peptic ulcer disease, and even cholangiocarcinoma. Ectopic opening of the common bile duct into the duodenal bulb is a rare form of ectopic opening of the common bile duct accounting for 0.1%-2.7% of cases of anomalous biliary drainage. Identification of such pathology is important because of its varied presentation and considerable operative and procedural implications. We report a rare case of duodenal bulb opening of the common bile duct in a patient who presented with cholangitis.

Diagnosis and Management of Lemmel Syndrome: An Unusual Presentation and Literature Review.

Lemmel syndrome is a rare clinical entity characterized by the presence of a periampullary duodenal diverticulum resulting in compression and dilatation of the pancreatic and common bile ducts, accompanied by obstructive jaundice. Gastric outlet obstruction is not a known complication of this syndrome, and there are no standardized approaches to its treatment. We present the first case of Lemmel syndrome presenting as gastric outlet obstruction and provide the results of a systematic literature review.

Atypical Manifestation of DRESS Syndrome.

The differential for liver transaminases over 1000 units/liter typically includes liver ischemia, acute viral hepatitis, acetaminophen toxicity, and autoimmune hepatitis. Prompt evaluation is imperative as these etiologies can lead to fulminant liver failure. We present a case of transaminases over 1000 units/liter from an atypical etiology. A 52-year-old male, previously treated with allopurinol for an acute gout flare, presented with persistent fevers. Given that he had taken a "high-risk medication" 2-6 weeks before presentation, subsequently presented with fever, rash, renal impairment, elevated liver enzymes in the thousands, and peripheral eosinophilia, DRESS syndrome secondary to allopurinol was diagnosed.

Pelvic Gastrointestinal Stromal Tumor With Pulmonary Metastasis.

Extragastrointestinal stromal tumors (EGISTs) comprise a small portion of gastrointestinal stromal tumors. Metastasis normally occurs to nearby organs. However, metastasis to the lungs is uncommon in EGISTs. Furthermore, recurrence of the EGIST in a new location years later has not been documented. We present this case to highlight this behavior of EGISTs in hopes to better understand this rare type of neoplasm.

Metabolic Pancreatitis: Pancreatic Steatosis, Hypertriglyceridemia, and Associated Chronic Pancreatitis in 3 Patients with Metabolic Syndrome.

Obesity, insulin resistance, and metabolic syndrome continue to increase in prevalence. Hypertriglyceridemia is commonly associated and represents a valuable marker of metabolic syndrome. An increase in subcutaneous fat deposition places patients at risk for visceral adipose deposition in sites such as the liver, heart, and pancreas. Pancreatic steatosis in the setting of metabolic syndrome is a rapidly emerging entity whose clinical spectrum remains to be defined. Hypertriglyceridemia is an accepted cause of acute pancreatitis but its role in chronic pancreatic injury remains to be explored. We present 3 patients with chronic abdominal pain and pancreatic steatosis in the setting of underlying metabolic syndrome with hypertriglyceridemia. These cases were identified in one endoscopic ultrasonographer's practice over a 12-month period. Each patient had documented hypertriglyceridemia but no history of acute hypertriglyceride-induced pancreatitis. A history of significant alcohol exposure was carefully excluded. Each patient underwent endoscopic ultrasonography (EUS) which proved critical in delineating the spectrum of chronic pancreatic injury. Each of our patients had EUS documentation of pancreatic steatosis and sufficient criteria to establish a diagnosis of chronic pancreatitis. Intraductal pancreatic calculi were identified in all 3 patients. Our series suggests that in the setting of metabolic syndrome, chronic hypertriglyceridemia and pancreatic steatosis may be associated with chronic pancreatitis. We hypothesize that hypertriglyceridemia may provide a pathogenic role in the development of chronic pancreatic microinjury. In addition, each of our patients had EUS-documented pancreatic ductal lithiasis. To our review, these are novel findings which have yet to be reported. We believe that with an enhanced awareness, it is likely that the entity of metabolic syndrome with features of pancreatic steatosis and hypertriglyceridemia with their associated manifestations of chronic pancreatitis, including ductal lithiasis, will be widely appreciated.

Effect of the Diagnosis of Inflammatory Bowel Disease on Risk-Adjusted Mortality in Hospitalized Patients with Acute Myocardial Infarction, Congestive Heart Failure and Pneumonia.

INTRODUCTION: Measurement of mortality in patients with acute myocardial infarction (AMI), congestive heart failure (CHF) and pneumonia (PN) is a high priority since these are common reasons for hospitalization. However, mortality in patients with inflammatory bowel disease (IBD) that are hospitalized for these common medical conditions is unknown. METHODS: A retrospective review of the 2005-2011 National Inpatient Sample (NIS), (approximately a 20% sample of discharges from community hospitals) was performed. A dataset for all patients with ICD-9-CM codes for primary diagnosis of acute myocardial infarction, pneumonia or congestive heart failure with a co-diagnosis of IBD, Crohn's disease (CD) or ulcerative colitis (UC). 1:3 propensity score matching between patients with co-diagnosed disease vs. controls was performed. Continuous variables were compared between IBD and controls. Categorical variables were reported as frequency (percentage) and analyzed by Chi-square tests or Fisher's exact test for co-diagnosed disease vs. control comparisons. Propensity scores were computed through multivariable logistic regression accounting for demographic and hospital factors. In-hospital mortality between the groups was compared. RESULTS: Patients with IBD, CD and UC had improved survival after AMI compared to controls. 94/2280 (4.1%) of patients with IBD and AMI died, compared to 251/5460 (5.5%) of controls, p = 0.01. This represents a 25% improved survival in IBD patients that were hospitalized with AMI. There was a 34% improved survival in patients with CD and AMI. There was a trend toward worsening survival in patients with IBD and CHF. Patients with CD and PN had improved survival compared to controls. 87/3362 (2.59%) patients with CD and PN died, compared to 428/10076 (4.25%) of controls, p < .0001. This represents a 39% improved survival in patients with CD that are hospitalized for PN. CONCLUSION: IBD confers a survival benefit for patients hospitalized with AMI. A diagnosis of CD benefits survival in patients that are hospitalized with PN.
