Background Nivolumab demonstrates promising efficacy for the treatment of non-small cell lung cancer and other malignancies. The clinical benefit of nivolumab, however, may be hampered by specific immune-related adverse events (irAEs), and little is known regarding nivolumab-related cholangitis. Methods A computerized search of our clinical database identified 3 metastatic non-small cell lung cancer patients with nivolumab-related cholangitis. All patients were treated with intravenous nivolumab monotherapy (3...

The biliary duct is an extremely rare site for colon cancer metastasis. It often leads to a diagnostic dilemma, since primary cholangiocarcinoma (potentially treatable with surgery) has a similar presentation. This paper highlights our experience with 5 consecutive patients who had colon malignancy with biliary metastasis, and prognosis of their disease. Five patients, with a history of primary colon cancer since 2010, were identified to have biliary metastasis. Of these, 4 (80.0%) patients were male. The median time to diagnosis of biliary metastasis from diagnosis of colon cancer was 59...

Purpose To analyze the cost effectiveness of the American Society for Gastrointestinal Endoscopy (ASGE) risk stratification guidelines versus magnetic resonance (MR) cholangiopancreatography-based treatment of patients with possible choledocholithiasis. Materials and Methods A decision-analytic model was constructed to compare cost and effectiveness of three diagnostic strategies for gallstone disease with possible choledocholithiasis: noncontrast MR cholangiopancreatography, contrast material-enhanced MR imaging/MR cholangiopancreatography, and ASGE risk stratification guidelines for diagnostic evaluation recommending endoscopy (high risk), MR cholangiopancreatography (intermediate risk), or no test (low risk)...

An adverse role for obstructive sleep apnea (OSA) in cancer epidemiology and outcomes has recently emerged from clinical and animal studies. In animals, intermittent hypoxia (IH) mimicking OSA promotes tumor malignancy both directly and via host immune alterations. We hypothesized that IH could potentiate cancer aggressiveness through activation of the cyclooxygenase-2 (COX-2) pathway and the concomitant increases in prostaglandin E2 (PGE2). The contribution of the COX-2 in IH-induced enhanced tumor malignancy was assessed using celecoxib as a COX-2 specific inhibitor in a murine model of OSA bearing Lewis lung carcinoma (LLC1) tumors...

Brunner's gland hamartoma, also called hyperplasia, adenoma, and Brunneroma, is an extremely rare benign proliferative lesion of Brunner's glands in the duodenum. While being mostly small and asymptomatic, they can result in gastrointestinal bleeding and obstruction. We report the case of a 54-year-old man presenting with melena and severe anemia requiring blood transfusion. CT scans showed a large mass of 8 cm in diameter, presumably arising in the duodenum. Endoscopic biopsies were not conclusive. As we were unable to determine the nature of the mass preoperatively and due to the severe symptoms, its size, and the uncertain malignant potential, a classic Whipple procedure was performed...

Extraskeletal osteosarcoma (ESOS) is an uncommon tumor that accounts for 1% of all soft tissue sarcomas and 4% of all osteosarcomas. Its presentation may be atypical, while pain has been described as the most common symptom. Radiological findings include a large mass in the soft-tissues with massive calcifications, but no attachment to the adjacent bone or periosteum. We present the case of a 73-year-old gentle man who presented with a palpable, tender abdominal mass and symptoms of bowel obstruction. Computer tomography images revealed a large space-occupying heterogeneous, hyper dense soft tissue mass involving the small intestine...

Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland. The most common locations of this displacement include the upper gastrointestinal tract-specifically, the stomach, duodenum, and proximal jejunum. Less common sites are the esophagus, ileum, Meckel diverticulum, biliary tree, mesentery, and spleen. Uncomplicated heterotopic pancreas is typically asymptomatic, with the lesion being discovered incidentally during an unrelated surgery, during an imaging examination, or at autopsy...

BACKGROUND: It remains unclear whether selection of treatment modality affects the survival of patients with malignant gastric outlet obstruction (GOO). We compared the effect of gastrojejunostomy (GJ) and endoscopic self-expandable metallic stent (SEMS) placement on the long-term outcomes of patients with malignant GOO caused by unresectable gastric cancer. METHOD: We conducted a retrospective study of gastric cancer patients undergoing GJ or endoscopic SEMS placement for the palliation of malignant GOO...

BACKGROUND: Endoscopic metallic stenting is widely accepted as a palliation therapy for malignant gastric outlet obstruction (GOO). However, the predictors of stent dysfunction have not been clarified. We aimed to evaluate the predictors, especially tumor ingrowth in uncovered self-expandable metallic stents (U-SEMS) and migration of covered self-expandable metallic stents (C-SEMS), which are the main causes related to the stent characteristics. METHODS: In this multicenter retrospective study, we compared patients with U-SEMS and C-SEMS in terms of clinical outcomes, and predictors of stent dysfunction...

INTRODUCTION: Pancreatic cysts are often observed incidentally on abdominal computed tomography (CT). For cysts involving intracystic nodules, malignant neoplasms such as intraductal papillary-mucinous carcinoma (IPMC) should be suspected. In contrast, cholesterol granuloma (CG) rarely occurs in the pancreas, and CG-associated autoimmune pancreatitis (AIP) has not yet been reported. To our knowledge, this is the first reported case of AIP with CG mimicking IPMC. PRESENTATION OF CASE: A 56-year-old woman underwent abdominal CT for preoperative breast cancer screening...

INTRODUCTION: Choledochal cysts are rare congenital dilations of the biliary tree that can present with non-specific symptoms such as abdominal pain, jaundice, cholelithiasis and pancreatitis. Although most commonly identified in children, they can be found in the adult population. However, because of the non-specific symptoms, this diagnosis may be difficult to make in the adult. A physician therefore must keep this diagnosis within their differential, as it may arise in an unexpected patient population who may present with a convoluted work up...

BACKGROUND: Malignant large bowel obstructions frequently require emergency surgery. Compliance with enhanced recovery after surgery programmes is significantly reduced due to non-removal of the nasogastric tube in the postoperative period. The first aim of the present study was to research factors associated with the failure of immediate nasogastric tube removal in patients who had undergone emergency surgery for malignant large bowel obstruction. The second aim was to assess the morbidity linked to nasogastric tube reinsertion...

REVIEW
Gerard Chaaya, Priya Vishnubhotla
The pulmonary veins (PVs) are the most proximal source of arterial thromboembolism. Pulmonary vein thrombosis (PVT) is a rare but potentially lethal disease; its incidence is unclear, as most of the literature includes case reports. It most commonly occurs as a complica-tion of malignancy, post lung surgery, or atrial fibrillation and can be idiopathic in some cases. Most patients with PVT are commonly asymptomatic or have nonspecific symptoms such as cough, hemoptysis, and dyspnea from pulmonary edema or infarction...

BACKGROUND: The antiplatelet effect of clopidogrel on blood loss and perioperative complications after surgical intervention remains ambiguous. The purpose of this study was to determine if patients on clopidogrel before hemiarthroplasty for femoral neck fracture are predisposed to greater surgical bleeding and perioperative complications compared with those not taking clopidogrel before surgery. METHODS: We conducted a review of our electronic medical record from 2006-2013 and identified 602 patients who underwent 623 hemiarthroplasty procedures for displaced femoral neck fracture, of which 54 cases (9%) were taking clopidogrel before hospital admission...
