Background and study aims: Many patients with acute gastrointestinal bleeding present with anemia and frequently require red blood cell (RBC) transfusion. A restrictive transfusion strategy and a low hemoglobin (Hb) threshold for transfusion had been shown to produce acceptable outcomes in patients with acute upper gastrointestinal bleeding. However, most patients are discharged with mild anemia owing to the restricted volume of packed RBCs (pRBCs). We investigated whether discharge Hb influences the outcome in patients with acute nonvariceal upper gastrointestinal bleeding. Patients and methods: We retrospectively analyzed patients with upper gastrointestinal bleeding who had received pRBCs during hospitalization between January 2012 and January 2014. Patients with variceal bleeding, malignant lesion, stroke, or cardiovascular disease were excluded. We divided the patients into 2 groups, low (8 g/dL ≤ Hb < 10 g/dL) and high (Hb ≥ 10 [g/dL]) discharge Hb, and compared the clinical course and Hb changes between these groups. Results: A total of 102 patients met the inclusion criteria. Fifty patients were discharged with Hb levels < 10 g/dL, whereas 52 were discharged with Hb levels > 10 g/dL. Patients in the low Hb group had a lower consumption of pRBCs and shorter hospital stay than did those in the high Hb group. The Hb levels were not fully recovered at outpatient follow-up until 7 days after discharge; however, most patients showed Hb recovery at 45 days after discharge. The rate of rebleeding after discharge was not significantly different between the 2 groups. Conclusions: In patients with acute upper gastrointestinal bleeding, a discharge Hb between 8 and 10 g/dL was linked to favorable outcomes on outpatient follow-up. Most patients recovered from anemia without any critical complication within 45 days after discharge.

During endoscopy of the esophagus fluorescence images were recorded at a delay of 20 ns after pulsed laser excitation simultaneously with conventional reflected white light images. To label malignant cells (dysplasia, tumor) 5-aminolaevulinic acid was applied prior to fluorescence guided bi-opsy. In this way pre-malignant and malignant lesions were detected not seen previously during routine endoscopy.

Waldmann's disease or Primary Intestinal Lymphangiectasia (PIL) is a rare disorder of gastrointestinal tract characterized by dilated lymphatics and widened villi causing leakage of lymph into intestinal lumen. Loss of lymph leads to hypoalbuminemia, hyogammaglobulinemia and lymphopenia. Secondary lymphangiectasia occurs secondary to an elevated lymphatic pressure as in lymphoma, systemic lupus erythematosus, constrictive pericarditis, cardiac surgeries (Fontan's procedure), inflammatory bowel disease and malignancies. We, hereby present a five-year-old male child who presented with abdominal distension and poor weight gain. He had hypoalbuminemia, lymphocytopenia and hypogammaglobulinemia. Upper gastrointestinal endoscopy showed normal gastric mucosa and punctate white lesions in duodenal mucosa with biopsy confirming intestinal lymphangiectasia. Secondary causes of intestinal lymphangiectasia were ruled out. Echocardiography revealed atrial septal defect which is an uncommon association with Waldmann's disease. He was started on low fat, high protein diet and medium chain triglyceride supplementation following which he improved symptomatically. High index of suspicion, early diagnosis and appropriate dietary treatment are necessary to alleviate symptoms as well as to achieve a sustainable growth and development in these children.

TC-325 is a novel endoscopic hemostatic powder. Our aim was to describe a single-center experience with the use of TC-325 in the upper and lower gastrointestinal tract, while for the first time attempting to determine how long the powder remains on a lesion. The charts of consecutive patients receiving TC-325 therapy between July 2011 and July 2013 were reviewed retrospectively. Primary endpoints included immediate hemostasis and early rebleeding (≤ 72 hours). Overall, 60 patients received 67 treatments with TC-325: 21 for nonmalignant nonvariceal upper gastrointestinal bleeding, 19 for malignant upper gastrointestinal bleeding, 11 for lower gastrointestinal bleeding, and 16 for intra-procedural bleeding. Immediate hemostasis was achieved in 66 cases (98.5 %), with 6 cases (9.5 %) of early rebleeding. No serious adverse events were noted. No TC-325 powder was identified in the 11 patients who underwent second-look endoscopy, performed within 24 hours in 4 patients. TC-325 appears safe and effective for managing bleeding in the upper and lower gastrointestinal tract with a variety of causes. The time during which the powder remains in the gastrointestinal tract is short, with complete elimination from the gastrointestinal tract as early as within 24 hours after use. © Georg Thieme Verlag KG Stuttgart · New York.

Background Recent guidelines from NICE have proposed that open access gastroscopy is largely limited to patients with “alarm” symptoms. Aims and methods This study reviewed the outcome of all our patients with verified oesophageal or gastric carcinoma who presented with uncomplicated dyspepsia to see if endoscopic investigation is warranted in this group. All patients with histologically verified upper gastrointestinal (GI) cancers who presented over a period from 1998 to 2002 were identified. Their presenting symptoms, treatment, and outcome were analysed. Results 228 upper GI cancers (119 oesophageal, 109 gastric; mean age 72 years (29–99 years); 130 male, 82 female) were identified in 11 145 endoscopies performed. Only 14 patients (6.2%) presented without alarm symptoms; three patients were under 55 years of age and all had gastric carcinoma—one of these had chronic diarrhoea only. Eleven had dyspepsia or reflux symptoms only, and two were under surveillance for Barrett's oesophagus. Only five patients had a curative surgical resection and are still alive two—six years from diagnosis. A sixth patient had a curative operation but died of a cerebrovascular accident one year later. The remaining eight patients unfortunately had either metastatic disease or comorbidity, which precluded surgery. All of these died within two years of diagnosis, mean survival 10 months. Conclusion Only five patients with dyspepsia and no alarm symptoms had resectable upper GI malignancies over a four year period. Limiting open access gastroscopy to those with alarm features only would “miss” a small number of patients who have curable upper GI malignancy. PMID:16397081

Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common medical emergency that can be life threatening. This study evaluated predictive factors of 30-day mortality in patients with this condition. A prospective observational study was conducted at a single hospital between April 2010 and November 2012, and 336 patients with symptoms and signs of gastrointestinal bleeding were consecutively enrolled. Clinical characteristics and endoscopic findings were reviewed to identify potential factors associated with 30-day mortality. Overall, 184 patients were included in the study (men, 79.3%; mean age, 59.81 years), and 16 patients died within 30 days (8.7%). Multivariate analyses revealed that comorbidity of diabetes mellitus (DM) or metastatic malignancy, age ≥ 65 years, and hypotension (systolic pressure < 90 mmHg) during hospitalization were significant predictive factors of 30-day mortality. Comorbidity of DM or metastatic malignancy, age ≥ 65 years, and hemodynamic instability during hospitalization were predictors of 30-day mortality in patients with NVUGIB. These results will help guide the management of patients with this condition.

INTRODUCTION Upper gastrointestinal endoscopy, traditionally performed in Cuba in specialized hospitals, was decentralized to the primary health care level in 2004 to make it more patient-accessible. OBJECTIVES Describe frequency and distribution of the principal symptomatic diseases of the upper gastrointestinal tract and their relation to the main risk factors associated with each in a sample of urban adults who underwent upper gastrointestinal endoscopy in primary care facilities in Havana in selected months of 2007. METHODS A multicenter cross-sectional study was conducted, including 3556 patients seen in the primary health care network of Havana from May through November 2007. The endoscopies were performed at the 22 polyclinics (community health centers) providing this service. Diagnostic quality and accuracy were assessed by experienced gastroenterologists using a validated tool. Patients responded to a questionnaire with clinical, epidemiologic, and sociodemographic variables. Univariate and multivariate analyses (unconditional logistical regression) were used to identify associated risk factors. The significance level was set at p < 0.05 (or confidence interval excluding 1.0). RESULTS The diagnoses were: gastritis (91.6%), duodenitis (57.8%), hiatal hernia (46.5%), esophagitis (25.2%), duodenal ulcer (15.8%), gastric ulcer (6.2%) and malignant-appearing lesions (0.4%). Overall prevalence of Helicobacter pylori infection was 58.4%. The main risk factors for duodenal ulcer were H. pylori infection (OR 2.70, CI 2.17-3.36) and smoking (OR 2.08, CI 1.68-2.58); and for gastric ulcer, H. pylori (OR 1.58, CI 1.17-2.15) and age ≥60 years (OR 1.78, CI 1.28-2.47). H. pylori infection was the main risk factor for gastritis (OR 2.29, CI 1.79-2.95) and duodenitis (OR 1.58, CI 1.38-1.82); and age ≥40 years for hiatal hernia (OR 1.57, CI 1.33-1.84). External evaluation was "very good" or "good" for 99.3% of endoscopic procedures and 97.9% of reports issued. CONCLUSIONS Gastrointestinal endoscopy performed in primary care yielded high quality results and important information about prevalence of the most common diseases of the upper GI tract and associated risk factors. This study provides a reference for new research and can inform objective recommendations for community-based interventions to prevent and control these diseases. The existence of a network of universally accessible diagnostic endoscopy services at the primary care level, will contribute to conducting further research.

Objective: To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension. Methods: There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People's Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting. Results: Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients' long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%. Conclusions: Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient's short-term prognosis after portal hypertension. Surgical intervention can reduce the rates of patients with upper gastrointestinal rebleeding, improve survival, and do not increase the incidence of malignant tumors.

Vitamin K for upper gastrointestinal bleeding in people with acute or chronic liver diseases.

Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. Several treatments are used for upper gastrointestinal bleeding in people with liver diseases. One of them is vitamin K administration, but it is not known whether it benefits or harms people with acute or chronic liver disease and upper gastrointestinal bleeding. This is an update of this Cochrane review. To assess the beneficial and harmful effects of vitamin K for people with acute or chronic liver disease and upper gastrointestinal bleeding. We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), and LILACS (1982 to 25 February 2015). We sought additional randomised trials from two registries of clinical trials: the World Health Organization Clinical Trials Search Portal and the metaRegister of Controlled Trials. We looked through the reference lists of the retrieved publications and review articles. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. We considered observational studies for assessment of harms only. \\We aimed to summarise data from randomised clinical trials using Standard Cochrane methodology and assess them according to the GRADE approach. We found no randomised trials on vitamin K for upper gastrointestinal bleeding in people with liver diseases assessing benefits and harms of the intervention. We identified no quasi-randomised studies, historically controlled studies, or observational studies assessing harms. This updated review found no randomised clinical trials of vitamin K for upper gastrointestinal bleeding in people with liver diseases. The benefits and harms of vitamin K need to be tested in randomised clinical trials. Until randomised clinical trials are conducted to assess the trade-off between benefits and harms, we cannot recommend or refute the use of vitamin K for upper gastrointestinal bleeding in people with liver diseases.

Delineating Extramammary Findings at Breast MR Imaging.

Breast magnetic resonance (MR) imaging is the only breast imaging modality that consistently encompasses extramammary structures in the thorax and upper abdomen. Incidental extramammary findings on breast MR images of patients with a history of breast cancer or other malignancies are significantly more likely to be malignant and may affect staging and treatment. An understanding of the frequency, distribution, and context of extramammary findings on breast MR images and a familiarity with common and uncommon sites of breast cancer metastasis inform the differential diagnosis and prompt the appropriate diagnostic next step, to differentiate benign from malignant findings. High-yield organ systems on breast MR images, as reflected by a high positive predictive value for malignancy, are correlated with known distant sites of breast cancer metastasis in the bone, lung, liver, and lymph nodes. Staging is considered when disease involves the skin and chest wall. Unusual sites of breast cancer metastasis from invasive lobular carcinoma are discussed, including the gastrointestinal tract, peritoneum, and adrenal glands. Nonmalignant clinically important findings involving the cardiovascular and gastrointestinal systems are reviewed, and potential pitfalls in diagnosis and interpretation are highlighted. A consistently systematic diagnostic approach is emphasized for identifying extramammary abnormalities on breast MR images. All things considered, the radiologist should be able to improve diagnostic sensitivity and specificity while interpreting extramammary findings on breast MR images. © RSNA, 2017.

There is a shortage of information on the epidemiology of digestive disease in developing countries. In the belief that such information will inform public health priorities and epidemiological comparisons between different geographical regions, we analysed 2132 diagnostic upper gastrointestinal endoscopy records from 1999 to 2005 in the University Teaching Hospital, Lusaka, Zambia. In order to clarify unexpected impressions about the age distribution of cancers, a retrospective analysis of pathology records was also undertaken. No abnormality was found in 31% of procedures, and in 42% of procedures in children. In patients with gastrointestinal haemorrhage, the common findings were oesophageal varices (26%), duodenal ulcer (17%) and gastric ulcer (12%). Gastrointestinal malignancy was found in 8.8% of all diagnostic procedures, in descending order of frequency: gastric adenocarcinoma, oesophageal squamous carcinoma, Kaposi's sarcoma, oesophageal adenocarcinoma. Data from endoscopy records and pathology records strongly suggest that the incidence in adults under the age of 45 years is higher than in the USA or UK, and pathology records suggest that this effect is particularly marked for colorectal carcinoma.

A 60-year-old man complained of nausea, vomiting, decreased appetite, and a feeling of abdominal fullness in August 2013. Based on biopsy findings from an upper gastrointestinal endoscopy examination, a diagnosis of non-Hodgkin's lymphoma (NHL), diffuse large B-cell lymphoma (DLBCL), non-GC type, was made. F18-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) revealed abnormal accumulations solely in the gastric wall (SUVmax = 14.5), the left adrenal gland (SUVmax = 14.3), and the right adrenal gland (SUVmax = 8.5). The clinical stage (Ann Arbor) was IVA, the serum LDH level was within the reference range, and the International Prognostic Index (IPI) was low-intermediate. The serum soluble IL-2 receptor level was within the reference range, and there was no evidence of HIV, EB virus, or autoimmune disease. After the completion of 4 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and 2 parallel cycles of prophylactic intrathecal (I.T.), an upper gastrointestinal endoscopy and a FDG-PET/CT examination showed complete remission (CR). The patient received 8 cycles of ritsuximab therapy, 6 cycles of CHOP, and 3 cycles of I.T. The patient has maintained a CR for about 14 months. A literature search revealed that malignant lymphoma with involvement confined to the adrenal gland and gastrointestinal tract is exceedingly rare, and only 3 cases of malignant lymphoma have been reported, with involvement of the stomach in 2 cases and the duodenum in 1 case. All of the cases were diagnosed as DLBCL. The case described herein represents the third case with involvement of the stomach.

Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. People with liver disease frequently have haemostatic abnormalities such as hyperfibrinolysis. Therefore, antifibrinolytic amino acids have been proposed to be used as supplementary interventions alongside any of the primary treatments for upper gastrointestinal bleeding in people with liver diseases. This is an update of this Cochrane review. To assess the beneficial and harmful effects of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver disease. We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), LILACS (1982 to February 2015), World Health Organization Clinical Trials Search Portal (accessed 26 February 2015), and the metaRegister of Controlled Trials (accessed 26 February 2015). We scrutinised the reference lists of the retrieved publications. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. Observational studies for assessment of harms. We planned to summarise data from randomised clinical trials using standard Cochrane methodologies and assessed according to the GRADE approach. We found no randomised clinical trials assessing antifibrinolytic amino acids for treating upper gastrointestinal bleeding in people with acute or chronic liver disease. We did not identify quasi-randomised, historically controlled, or observational studies in which we could assess harms. This updated Cochrane review identified no randomised clinical trials assessing the benefits and harms of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver disease. The benefits and harms of antifibrinolytic amino acids need to be tested in randomised clinical trials. Unless randomised clinical trials are conducted to assess the trade-off between benefits and harms, we cannot recommend or refute antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver diseases.

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

Acute upper gastrointestinal bleeding (UGIB) is the most common reason that the 'on-call' gastroenterologist is consulted. Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.

Hematemesis and acute postsurgical upper gastrointestinal hemorrhage are common emergent on-call consultations for the interventional radiologist. Upper GI bleleding (UGIB) is a relatively frequent problem. The incidence and mortality vary among patient populations, but studies have shown an overall incidence ranging from 36-172 cases per 100,000 adults per year, with a mortality rate of 5%-14%. The incidence is significantly higher in men. Peptic ulcer disease is the predominant etiology, responsible for 28%-59% of UGIB. Other causes include varices, mucosal erosive disease, Mallory-Weiss syndrome, and malignancy. After assessment of hemodynamic status and airway stability with resuscitative efforts as needed, initial consultation with gastroenterology for endoscopic evaluation and treatment is well regarded as the initial therapeutic strategy. Angiography with embolization and interventional techniques directed at managing variceal hemorrhage have emerged as very capable second-line strategies for patients who have failed endoscopic therapy. In certain circumstances, the interventional radiologist may be called upon as the first line, notably for patients who have had recent surgical intervention or who have extraluminal hemorrhage. As the role of the interventional radiologist in the evaluation and treatment of UGIB continues to evolve, familiarity and knowledge of how to deal with these urgent and emergent clinical scenarios becomes paramount.

To evaluate the prevalence of upper gastrointestinal symptoms and their association with clinical and functional characteristics in elderly outpatients. The study involved 3238 outpatients ≥ 60 years consecutively enrolled by 107 general practitioners. Information on social, behavioral and demographic characteristics, function in the activities of daily living (ADL), co-morbidities and drug use were collected by a structured interview. Upper gastrointestinal symptom data were collected by the 15-items upper gastro-intestinal symptom questionnaire for the elderly, a validated diagnostic tool which includes the following five symptom clusters: (1) abdominal pain syndrome; (2) reflux syndrome; (3) indigestion syndrome; (4) bleeding; and (5) non-specific symptoms. Presence and severity of gastrointestinal symptoms were analyzed through a logistic regression model. 3100 subjects were included in the final analysis. The overall prevalence of upper gastrointestinal symptoms was 43.0%, i.e. cluster (1) 13.9%, (2) 21.9%, (3) 30.2%, (4) 1.2%, and (5) 4.5%. Upper gastrointestinal symptoms were more frequently reported by females (P < 0.0001), with high number of co-morbidities (P < 0.0001), who were taking higher number of drugs (P < 0.0001) and needed assistance in the ADL. Logistic regression analysis demonstrated that female sex (OR = 1.39, 95% CI: 1.17-1.64), disability in the ADL (OR = 1.47, 95% CI: 1.12-1.93), smoking habit (OR = 1.29, 95% CI: 1.00-1.65), and body mass index (OR = 1.06, 95% CI: 1.04-1.08), as well as the presence of upper (OR = 3.01, 95% CI: 2.52-3.60) and lower gastroenterological diseases (OR = 2.25, 95%CI: 1.70-2.97), psychiatric (OR = 1.60, 95% CI: 1.28-2.01) and respiratory diseases (OR = 1.25, 95% CI: 1.01-1.54) were significantly associated with the presence of upper gastrointestinal symptoms. Functional and clinical characteristics are associated with upper gastrointestinal symptoms. A multidimensional comprehensive evaluation may be useful when approaching upper gastrointestinal symptoms in older subjects.

[Non-Helicobacter pylori, Non-nonsteroidal Anti-inflammatory Drug Peptic Ulcer Disease].

PubMed

Chang, Young Woon

2016-06-25

Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

Changes in upper gastrointestinal physiology with age.

PubMed

Newton, J L

2004-12-01

Diseases of the upper gastrointestinal tract such as peptic ulceration and gastric cancer become more common and more severe with advancing age. In the normal stomach and duodenum, there is a balance between mucosal protective mechanisms and endogenous (gastric acid and pepsin) and exogenous aggressive factors. The high incidence of gastrointestinal pathology seen in older age groups is not related to increase in the secretion of endogenous aggressive factors. Recent work suggests that gastrointestinal mucosal protective mechanisms are impaired with age. The roles in the gastrointestinal tract of molecules that have been implicated in mucosal repair, such as trefoil peptides and matrix components, are beginning to be elucidated and their study in older people is essential to ensure appropriate, efficient, cost-effective management of gastric pathology in the elderly. Strategies to improve the management of upper gastrointestinal diseases in older people will reduce mortality and improve quality of life.

To evaluate the prognostic factors, including risk scores (Glasgow-Blatchford score and AIMS65) in patients with acute upper or lower gastrointestinal bleeding. The medical records of patients who had undergone emergency gastrointestinal endoscopy for suspected gastrointestinal bleeding during the past 5 years were retrospectively analyzed. A total of 232 endoscopies (130 esophagogastroduodenoscopies, 102 colonoscopies) for 192 patients met the inclusion criteria. Median age was 66 years, and 64% of patients were males. Endoscopy identified causes for bleeding in 173 patients (post-endoscopic interventions for neoplastic lesions in 36 cases, colonic diverticula in 34, gastroduodenal ulcers in 29, gastric erosions in 15, vascular ectasia in 14, post-biopsy bleeding in 13, malignant tumors in 10, inflammatory conditions in nine, esophagogastric varices in five, Mallory-Weiss tears in four, nasalbleeding in three, and injury by swallowed blister pack in one), whereas the source of bleeding remained obscure in 19 patients. Blood transfusion was given in 97 patients (51%), and 97 (51%) underwent endoscopic hemostasis. During the follow-up period, 49 patients (26%) experienced rebleeding, seven of whom were treated by interventional radiology. Thirty-nine patients (20%) died as a result of various diseases. The probabilities of overall survival (OS) after 3 and 5 years were 71% and 67%, respectively. Cox multivariate analysis revealed blood transfusion, co-existing malignancy, absence of endoscopic hemostasis, and high AIMS65 score to be independent prognostic factors for poor OS. The AIMS65 score is useful for predicting the prognosis of patients with acute gastrointestinal bleeding. © 2013 The Authors. Digestive Endoscopy © 2013 Japan Gastroenterological Endoscopy Society.

Background and Objectives: After the widespread application of minimally invasive surgery for benign diseases and given its proven safety and efficacy, minimally invasive surgery for gastrointestinal cancer has gained substantial attention in the past several years. Despite the large number of publications on the topic and level I evidence to support its use in colon cancer, minimally invasive surgery for most gastrointestinal malignancies is still underused. Methods: We explore some of the challenges that face the fusion of minimally invasive surgery technology in the management of gastrointestinal malignancies and propose solutions that may help increase the utilization in the future. These solutions are based on extensive literature review, observation of current trends and practices in this field, and discussion made with experts in the field. Results: We propose 4 different solutions to increase the use of minimally invasive surgery in the treatment of gastrointestinal malignancies: collaboration between surgical oncologists/hepatopancreatobiliary surgeons and minimally invasive surgeons at the same institution; a single surgeon performing 2 fellowships in surgical oncology/hepatopancreatobiliary surgery and minimally invasive surgery; establishing centers of excellence in minimally invasive gastrointestinal cancer management; and finally, using robotic technology to help with complex laparoscopic skills. Conclusions: Multiple studies have confirmed the utility of minimally invasive surgery techniques in dealing with patients with gastrointestinal malignancies. However, training continues to be the most important challenge that faces the use of minimally invasive surgery in the management of gastrointestinal malignancy; implementation of our proposed solutions may help increase the rate of adoption in the future.

Upper gastrointestinal bleeding - state of the art.

PubMed

Szura, Mirosław; Pasternak, Artur

2014-01-01

Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

Bidirectional endoscopy (BE) is often used to assess patients for the reason of anemia or to screen asymptomatic population for malignancy. Limited clinical data favors to perform first the upper gastrointestinal system endoscopy, but its effect to the duration of colonoscopy is yet to be determined. The aim of this retrospective study is to evaluate the effect of upper gastrointestinal system endoscopy on the time to achieve cecal intubation during colonoscopy in patients undergoing BE. Patients of four endoscopists at similar experience levels were retrospectively identified and categorized into the upper gastrointestinal system endoscopy before colonoscopy group (group 1) or the colonoscopy only group (group 2). The demographics, clinical data and the time to achieve cecal intubation for each patient were analyzed. The mean time to achieve cecal intubation in the first group that included 319 cases was 8.4 ± 0.93 minutes and the mean time in the second group that included 1672 cases was 8.56 ± 1.16 minutes. There was no statistically significant difference between the groups. There was also no significant difference between the Group 1 and Group 2 when compared according to which of the four endoscopists performed the procedures. Performing the upper gastrointestinal system endoscopy prior to colonoscopy did not affect the time to achieve cecal intubation. Considering that performing the upper gastrointestinal system endoscopy prior to the colonoscopy is more advantageous in terms of patient comfort and analgesic requirement, beginning to BE with it seems more favorable.

Gastroduodenal tuberculosis is a rare location of abdominal tuberculosis. It usually occurs secondary to pulmonary tuberculosis. We report a case of a 63-year-old woman admitted to the referral center for symptoms of upper gastrointestinal obstruction caused by ulcerohypertrophic antroduodenal tuberculosis. The lesion was misdiagnosed as malignancy at endoscopy. Even at surgery, the lesion was considered gastric cancer and imposed an oncologic resection. The diagnosis was established in the presence of giant-cell granulomas with caseating necrosis in the surgical resected specimens. In our case, the rare gastroduodenal location of abdominal tuberculosis occurred as primary tuberculosis, in the absence of other identifiable locations.

Diet and Upper Gastrointestinal Malignancies

PubMed Central

Abnet, Christian C.; Corley, Douglas A.; Freedman, Neal D.; Kamangar, Farin

2015-01-01

Diet is believed to modulate cancer risk and this relationship has been widely studied in the gastrointestinal tract. Observational epidemiologic studies have provided most of the evidence for the effects of diet on cancer risk, because clinical trials to determine nutritional exposures are often impossible, impractical, or unaffordable. Although a few foods or nutrients are thought to protect against specific types of cancer, it seems clear that the strength and even direction of dietary associations (increasing or decreasing risk) is organ site- and even histology-specific, along the gastrointestinal tract. Although some hypotheses are supported by a substantial body of observational data (drinking hot maté contributes to esophageal cancer), there is not much data to support others. We discuss some highly touted hypotheses and draw interim conclusions about what is known, and what could be done to improve the level of evidence. The complex nature of diet and its associations can be productively investigated with disease-specific studies. However, public health recommendations for normal-risk individuals regarding diet and gastrointestinal cancer should probably emphasize the importance of eating for overall health, rather than eating specific foods to reduce risk for specific cancers.

Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and peptic ulcer are considered as the major factors for upper gastrointestinal system bleeding. The objective of the study was to determine the sociodemographic and etiologic factors, management and outcome of patients with non-variceal upper gastrointestinal system bleeding in Turkey. Patients who admitted to hospitals with upper gastrointestinal system bleeding and in whom upper gastrointestinal endoscopy was performed were enrolled in this retrospective study. The detailed data of medical history, comorbid diseases, medications, admission to intensive care units, Helicobacter pylori infection, blood transfusion, upper gastrointestinal endoscopy, and treatment outcome were documented. The most frequent causes of bleeding (%) were duodenal ulcer (49.4), gastric ulcer (22.8), erosion (9.6), and cancer (2.2) among 1,711 lesions in endoscopic appearances of 1,339 patients from six centers. Seven hundred and four patients were evaluated for Helicobacter pylori infection and the test was positive in 45.6% of those patients. Comorbid diseases were present in 59.2% of the patients. The percentage of patients using acetylsalicylic acid and/or other non-steroidal anti-inflammatory drug was 54.3%. Bleeding was stopped with medical therapy in 66.9%. Only 3.7% of the patients underwent emergency surgery, and a 1.1% mortality rate was determined. Patients with upper gastrointestinal system bleeding were significantly older, more likely to be male, and more likely to use non-steroidal anti-inflammatory drugs. Though most of the patients were using gastro-protective agents, duodenal and gastric ulcers were the contributing factors in more than 70% of the upper gastrointestinal bleeding. The extensive use of non-steroidal anti-inflammatory drug is a hazardous health issue considering the use of these drugs in half of the patients.

The enormous increase in theoretical knowledge and technical possibilities in general surgery has led to differentiation and subspecialization. Gastrointestinal surgery is now recognized as a distinguished area of specific interest within the field of general surgery. It covers the surgical diagnosis and treatment of benign and malignant diseases of the digestive tract, including liver and pancreas. Most gastrointestinal diseases require a multidisciplinary approach in which the gastroenterologist and the gastrointestinal surgeon are key figures. This Journal is planning a series of articles highlighting the recent developments and current state of the art of gastrointestinal surgery, with special emphasis on the close connection with gastroenterology.

Excess Long-Term Mortality following Non-Variceal Upper Gastrointestinal Bleeding: A Population-Based Cohort Study

Crooks, Colin John; Card, Timothy Richard; West, Joe

2013-01-01

Background It is unclear whether an upper gastrointestinal bleed is an isolated gastrointestinal event or an indicator of a deterioration in a patient's overall health status. Therefore, we investigated the excess causes of death in individuals after a non-variceal bleed compared with deaths in a matched sample of the general population. Methods and Findings Linked longitudinal data from the English Hospital Episodes Statistics (HES) data, General Practice Research Database (GPRD), and Office of National Statistics death register were used to define a cohort of non-variceal bleeds between 1997 and 2010. Controls were matched at the start of the study by age, sex, practice, and year. The excess risk of each cause of death in the 5 years subsequent to a bleed was then calculated whilst adjusting for competing risks using cumulative incidence functions. 16,355 patients with a non-variceal upper gastrointestinal bleed were matched to 81,523 controls. The total 5-year risk of death due to gastrointestinal causes (malignant or non-malignant) ranged from 3.6% (≤50 years, 95% CI 3.0%–4.3%) to 15.2% (≥80 years, 14.2%–16.3%), representing an excess over controls of between 3.6% (3.0%–4.2%) and 13.4% (12.4%–14.5%), respectively. In contrast the total 5-year risk of death due to non-gastrointestinal causes ranged from 4.1% (≤50 years, 3.4%–4.8%) to 46.6% (≥80 years, 45.2%–48.1%), representing an excess over controls of between 3.8% (3.1%–4.5%) and 19.0% (17.5%–20.6%), respectively. The main limitation of this study was potential misclassification of the exposure and outcome; however, we sought to minimise this by using information derived across multiple linked datasets. Conclusions Deaths from all causes were increased following an upper gastrointestinal bleed compared to matched controls, and over half the excess risk of death was due to seemingly unrelated co-morbidity. A non-variceal bleed may therefore warrant a careful assessment of co-morbid illness seemingly unrelated to the bleed. Please see later in the article for the Editors' Summary PMID:23637580

AIM: To evaluate the prevalence of upper gastrointestinal symptoms and their association with clinical and functional characteristics in elderly outpatients. METHODS: The study involved 3238 outpatients ≥ 60 years consecutively enrolled by 107 general practitioners. Information on social, behavioral and demographic characteristics, function in the activities of daily living (ADL), co-morbidities and drug use were collected by a structured interview. Upper gastrointestinal symptom data were collected by the 15-items upper gastro-intestinal symptom questionnaire for the elderly, a validated diagnostic tool which includes the following five symptom clusters: (1) abdominal pain syndrome; (2) reflux syndrome; (3) indigestion syndrome; (4) bleeding; and (5) non-specific symptoms. Presence and severity of gastrointestinal symptoms were analyzed through a logistic regression model. RESULTS: 3100 subjects were included in the final analysis. The overall prevalence of upper gastrointestinal symptoms was 43.0%, i.e. cluster (1) 13.9%, (2) 21.9%, (3) 30.2%, (4) 1.2%, and (5) 4.5%. Upper gastrointestinal symptoms were more frequently reported by females (P < 0.0001), with high number of co-morbidities (P < 0.0001), who were taking higher number of drugs (P < 0.0001) and needed assistance in the ADL. Logistic regression analysis demonstrated that female sex (OR = 1.39, 95% CI: 1.17-1.64), disability in the ADL (OR = 1.47, 95% CI: 1.12-1.93), smoking habit (OR = 1.29, 95% CI: 1.00-1.65), and body mass index (OR = 1.06, 95% CI: 1.04-1.08), as well as the presence of upper (OR = 3.01, 95% CI: 2.52-3.60) and lower gastroenterological diseases (OR = 2.25, 95%CI: 1.70-2.97), psychiatric (OR = 1.60, 95% CI: 1.28-2.01) and respiratory diseases (OR = 1.25, 95% CI: 1.01-1.54) were significantly associated with the presence of upper gastrointestinal symptoms. CONCLUSION: Functional and clinical characteristics are associated with upper gastrointestinal symptoms. A multidimensional comprehensive evaluation may be useful when approaching upper gastrointestinal symptoms in older subjects. PMID:21799648

Merkel cell cancer is an aggressive cutaneous malignancy of neuroendocrine cell lineage which carries a poor prognosis. It usually affects elderly Caucasians and presents as a firm, painless, nodular lesion on the sun exposed areas of the body. Though it is highly metastatic, metastasis to the gastrointestinal tract is rarely reported. We describe a case of gastric metastasis from merkel cell cancer presenting with upper gastrointestinal bleeding. To our knowledge, only 8 such cases have been reported in English literature so far.

A 62-year-old man with a chief complaint of dysphagia visited our hospital. Enhanced computed tomography showed the tumor near the duodenal wall and lymphadenopathy in the left supraclavicular fossa and para-aortic lymph node. Upper gastrointestinal endoscopy showed an ulcer accompanied with a fistula in the anterior wall of duodenal bulb, suggesting that the tumor penetrated into duodenal wall. Biopsy from the lymph node in the left supraclavicular fossa indicated diffuse large B-cell lymphoma. Although chemotherapy was planned, massive arterial bleeding occurred from the part of duodenal penetration. Endoscopic hemostasis was unsuccessfully performed. Therefore, we performed transcathether arterial embolization for hemostasis. After the procedure, the patient received six cycles of chemotherapy, and he achieved complete response. He has been alive 5 years without recurrence. There were many cases of gastrointestinal bleeding from primary gastrointestinal lymphomas, while there were few cases with nodal involvement by malignant lymphoma resulting in bleeding from gastrointestinal tract. We herein report a case of duodenal bleeding by nodal involvement of diffuse large B-cell lymphoma with review of literature.

Malignancy, weight loss, and the small intestinal mucosa

PubMed Central

Barry, R. E.

1974-01-01

The mucosal architecture and mucosal dynamics of the small bowel have been studied in patients with malignant disease not of the gastrointestinal tract but associated with severe weight loss. Mucosal changes in malignant disease are demonstrated by stereomicroscopy, mucosal architectural measurement, and decreased lactose utilization. Measurement of the epithelial DNA loss rate indicates, in association with mucosal measurement, that the architectural changes are caused by a hypoplasia of the epithelium. Similar findings are demonstrated in patients with profound weight loss due to other non-malignant wasting diseases. Although mucosal changes undoubtedly occur in malignant disease, the changes are not specific for malignancy and the concept of `cancer enteropathy' is not tenable. It is suggested that mucosal changes are the effect of and not the cause of cachexia. ImagesFig 1 PMID:4430474

The objectives of this study were to define the utility of esophagogastroduodenoscopy in the diagnosis and management of patients presenting with dysphagia and to determine the relative incidence of the various causes of dysphagia in Sudan. This is a prospective, cross-sectional, descriptive, hospital-based study carried out at the endoscopy unit of Soba University Hospital, Khartoum, Sudan. All patients complaining of dysphagia underwent upper gastrointestinal endoscopy with therapeutic intervention when necessary. A total of 114 patients were enrolled in the study, with a mean age of 47 years SD +/- 19 and a male to female ratio of 1 : 1.04. A benign condition was diagnosed in 56% of the cases; this included esophageal strictures in 21% of the cases and achalasia in 14%. Malignant causes were mainly due to esophageal cancer (40.4%) and cancer of the stomach cardia (3.5%). Therapeutic intervention was attempted in 83% of the cases. Risk factors predictive of a malignant etiology were age over 40 years (P < 0.000), dysphagia lasting between 1 month and 1 year (P < 0.000), and weight loss (P < 0.000). A barium study was performed in 35 cases (31%) prior to endoscopic examination and proved to be inaccurate in three cases (8.6%). Upper gastrointestinal endoscopy in our African setting is an accurate and useful investigation in the diagnosis and management of patients presenting with dysphagia. Patients over the age of 40 years presenting with dysphagia and weight loss are more likely to have a neoplastic disease and should be referred for urgent endoscopy.

It focuses on gastroesophageal reflux disease and other esophageal motor disorders for the esophagus and on gastroparesis and accelerated gastric emptying for the stomach. It also describes differences in upper GI motility signs and symptoms during each female hormonal stage (ie, menstrual cycle, pregnancy, perimenopause, menopause) for both healthy participants and those suffering from one of the aforementioned upper GI dysmotility conditions. More research still needs to be conducted to better understand sex differences in upper GI motility. Copyright © 2016 Elsevier Inc. All rights reserved.

Abstract Rationale: Only a few cases of putative lung adenocarcinoma presenting as carcinoma of unknown primary site (CUP) with epidermal growth factor receptor (EGFR) mutation have been reported, and the efficacy of EGFR-tyrosine kinase inhibitors (TKIs) for these cases is unclear. Patient concerns and diagnoses: A 67-year-old man complained of paresis of the right lower extremity, dysarthria, and memory disturbance. Computed tomography and magnetic resonance imaging showed multiple brain tumors with brain edema and swelling of the left supraclavicular, mediastinal, and upper abdominal lymph nodes. Moreover, a metastatic duodenal tumor was detected via upper gastrointestinal endoscopy examination. The biopsy specimen of the lesion was examined and was diagnosed as adenocarcinoma with CK7 and TTF-1 positivity. Finally, the case was diagnosed as EGFR mutation-positive putative lung adenocarcinoma presenting as CUP. Interventions and outcomes: Oral erlotinib, an EGFR-TKI, was administered at 150 mg daily. Five weeks later, the brain lesions and several swollen lymph nodes showed marked improvement, and the symptoms of the patient also improved. Three months later, the duodenal lesion was undetected on upper gastrointestinal endoscopy. After an 8-month follow-up, the patient was well with no disease progression. Lessons: Putative lung adenocarcinoma presenting as CUP may have EGFR mutation, and EGFR-TKI therapy may be effective for such malignancy. PMID:29443782

Impact of acid suppressants on lower gastrointestinal bleeding remains unclear in low-dose aspirin users; we aimed to investigate this relationship. Retrospective cohort study of low-dose aspirin users who underwent coronary angiography for ischaemic heart disease in our institution between October 2005 and December 2006; patients were evaluated for upper or lower gastrointestinal bleedings within 3 years post-angiography. 538 patients were enrolled (males, 74.4%; mean age 67.4±10.6 years). Risk for upper gastrointestinal bleeding decreased with concomitant use of statins (HR, 0.37; 95% CI, 0.15-0.89), calcium channel blockers (HR, 0.29; 95% CI, 0.10-0.85), and histamine-2 receptor antagonists (HR, 0.26; 95% CI, 0.08-0.89). Concomitant use of proton pump inhibitors tended to decrease risk of upper gastrointestinal bleeding (HR, 0.27; 95% CI, 0.06-1.18). Risk for lower gastrointestinal bleeding increased with both concomitant use of warfarin (HR, 15.68; 95% CI, 4.43-55.53) and proton pump inhibitors (HR, 6.55; 95% CI, 2.01-21.32), but not with histamine-2 receptor antagonists. Hyperuricemia lowered risk for lower gastrointestinal bleeding (HR, 0.12; 95% CI, 0.02-0.88). In low-dose aspirin users, concomitant use of proton pump inhibitors increased lower gastrointestinal bleeding risk, independent from effects on upper gastrointestinal bleeding.

Von Recklinghausen disease is a syndrome characterized by a wide phenotypic variability giving rise to both, cutaneous and visceral benign and malignant neoplasms. The first include cutaneous neurofibromas, subcutaneous and plexiform neurofibromas. The latter can undergo malignant transformation and/or determine elephantiasis neuromatosa. Visceral tumors may include malignant peripheral nerve sheet tumors, gastrointestinal stromal tumors, cerebral gliomas and abdominal neurofibromas. In the present study, the authors discuss the clinical and biomolecular characterization of a cohort of 20 families with a diagnosis of type 1 neurofibromatosis. Clinically, the cohort includes three probands with elephantiasis neuromatosa and a peculiarly high incidence of breast and gastrointestinal cancer. Among the 14 NF1 mutations documented, 10 encoding for a truncated protein have been associated to particularly aggressive clinical phenotypes including elephantiasis neuromatosa, malignant peripheral nerve sheet tumors, breast cancer, gastrointestinal stromal tumors. This effect on protein synthesis, rather than the type of NF1 mutation, is the key to the explanation of the genotype-phenotype correlations in the context of neurofibromatosis type 1.

An international working party at the World Congress of Gastroenterology held in Vienna, Austria from September 6 to 11, 1998 defined a classification for Crohn's disease based on patient age at diagnosis (eg, less than 40 years of age, 40 years of age or older), disease location (eg, terminal ileum, colon, ileocolon or upper gastrointestinal tract) and behaviour (eg, stricturing, penetrating). Disease location in the upper gastrointestinal tract was defined by disease being present proximal to the terminal ileum, regardless of terminal ileal or colon involvement. A 20-year, single clinician database of 877 patients from a university campus hospital was used, and comprised 492 women (56.1%) and 385 men (43.9%). Of these patients, 740 (84.4%) were diagnosed before age 40 years and 137 (15.6%) were diagnosed by 40 years of age or older. Disease was located in the terminal ileum alone in 222 patients (25.3%), colon alone in 238 patients (27.2%) and ileocolon in 304 patients (34.6%). Another 113 patients (13.1%) had disease in the upper gastrointestinal tract, usually with disease also in the terminal ileum (23 patients), colon (12 patients) or ileocolon (71 patients). Only seven of 877 patients had disease located in the upper gastrointestinal tract alone with no distal disease. Disease behaviour could be classified as nonstricturing and nonpenetrating in 256 patients (29.2%), stricturing in 294 patients (33.6%) and penetrating in 327 patients (37.2%). Of the 877 patients with Crohn's disease, 837 were white, 38 were Asian and two were black. In this tertiary care setting of a single clinician practice in a Canadian teaching hospital at the University of British Columbia, Crohn's disease predominantly affects women, and young adults with a high rate of stricturing and penetrating complications.

Background Patients with malignant tumours of the upper gastrointestinal tract tumours exhibit important alarm symptoms such as dysphagia that warrant clinical investigations. An endoscopic examination of the upper gastrointestinal tract will be required in most cases. This study evaluates the diagnostic potential of index endoscopy in a random population of patients with dysphagia. Methods This is a retrospective analysis of prospectively collected data over 10 years. Patients with previous endoscopic evaluation or upper gastrointestinal pathology were excluded from the study. Data was analysed to see the number and frequency of abnormal findings in upper gastrointestinal tract, and their significance in relation to the presenting symptoms. Results Total number of index endoscopies was 13, 881. 913 patients were included in the study including 465 males (age range: 17–92 years, median: 55 years) and 448 females (age range: 18–100, median: 59 years), with male to female ratio of 1.04: 1. Oesophagus was abnormal in 678 cases (74%) and biopsies were taken in 428 patients (47%). Superficial oesophagitis, Barrett's oesophagus, oesophageal cancer, and oesophageal ulcer were main histological findings. Age more than 50 years and weight loss were significant predictors of oesophageal cancer (p < 0.0001). Male gender, heartburn, epigastric pain, weight loss and vomiting were significantly related to Barrett's oesophagus. A total of 486 gastric and 56 duodenal biopsies were also taken. There were 20 cases of gastric adenocarcinoma. Conclusion OGD is an effective initial investigation to assess patients with dysphagia, especially males above the age of 50 years. Patients may be started on treatment or referred for further investigations, for example, a barium meal in the absence of any anatomical abnormality. PMID:18034883

Measurements of tissue Zn in humans with upper gastrointestinal disease could provide information about underlying pathophysiology but these data have never been obtained. With recent endoscopic methods they obtained 2-6 mg pinch mucosal biopsies of epithelium and lamina propria from proximal (P), middle (M) and distal (D) areas of esophagus under direct vision through a flexible 1 cm endoscope in 35 subjects without gastrointestinal disease (N) and in 35 patients with the following endoscopically proven gastrointestinal pathology: 12 with esophagitis (E), 14 with duodenal ulcer disease (DU) and 9 with gastritis (G). Samples were dried, weighed, digested with HNO/sub 3/,more » dried, resuspended in 3% HNO/sub 3/ and Zn estimated by flame atomic absorption spectrophotometry. Esophageal Zn in N decreased progressively as biopsies extended from P to D (P, 108 +/- 29 ..mu..g/g dry weight, Mean +/- SEM; M, 158 +/- 23; D, 134 +/- 16) but this pattern was generally reversed in patients, with D consistently demonstrating Zn elevated 50-120% above normal. The greatest increase was in G in whom Zn in D was more than twice normal (DU, 290 +/- 76, p < 0.01). These are the first Zn levels obtained from esophagus in living human subjects and indicate (1) a specific pattern of Zn distribution in normal esophagus and (2) a significantly altered pattern in D in several diseases of the upper gastrointestinal tract.« less

Upper non-variceal gastrointestinal bleeding - review the effectiveness of endoscopic hemostasis methods

PubMed Central

Szura, Mirosław; Pasternak, Artur

2015-01-01

Upper non-variceal gastrointestinal bleeding is a condition that requires immediate medical intervention and has a high associated mortality rate (exceeding 10%). The vast majority of upper gastrointestinal bleeding cases are due to peptic ulcers. Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and aspirin are the main risk factors for peptic ulcer disease. Endoscopic therapy has generally been recommended as the first-line treatment for upper gastrointestinal bleeding as it has been shown to reduce recurrent bleeding, the need for surgery and mortality. Early endoscopy (within 24 h of hospital admission) has a greater impact than delayed endoscopy on the length of hospital stay and requirement for blood transfusion. This paper aims to review and compare the efficacy of the types of endoscopic hemostasis most commonly used to control non-variceal gastrointestinal bleeding by pooling data from the literature.

There exists a complex interplay between asthma and gastroesophageal reflux disease. Both these diseases are known to aggravate each other and amelioration of one is necessary for the control of the other. There is a paucity of studies in Indian population on this subject. To evaluate the clinical features and the endoscopic findings of the upper gastrointestinal tract in patients with bronchial asthma. Study was conducted at KMC group of hospitals, Mangalore in the Department of chest medicine in association with Department of gastroenterology. Subjects included 50 cases of bronchial asthma and controls were 58 non asthmatic patients with allergic rhinitis and chronic urticaria. All patients were queried about presence or absence of symptoms of upper gastro intestinal tract disorders by gastro oesophageal reflux disease (GERD) questionnaire and all the included patients underwent upper gastro intestinal endoscopy. The study showed that symptoms of gastroesophageal reflux were significantly more in asthmatics (52%) as compared to the controls (28%). The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or endoscopic evidence of upper gastrointestinal disorder and gastroesophageal reflux disease was found in significantly higher proportion of the asthmatics as compared to the controls. Clinically silent gastroesophageal reflux disease was however seen in both control and asthmatic groups equally with a lower prevalence.

Diagnosis and Treatment of Gastrointestinal Disorders in Patients With Primary Immunodeficiency

PubMed Central

AGARWAL, SHRADHA; MAYER, LLOYD

2013-01-01

Gastrointestinal disorders such as chronic or acute diarrhea, malabsorption, abdominal pain, and inflammatory bowel diseases can indicate immune deficiency. The gastrointestinal tract is the largest lymphoid organ in the body, so it is not surprising that intestinal diseases are common among immunodeficient patients. Gastroenterologists therefore must be able to diagnose and treat patients with primary immunodeficiency. Immune-related gastrointestinal diseases can be classified as those that develop primarily via autoimmunity, infection, an inflammatory response, or malignancy. Immunodeficient and immunocompetent patients with gastrointestinal diseases present with similar symptoms. However, intestinal biopsy specimens from immunodeficient patients often have distinct histologic features, and these patients often fail to respond to conventional therapies. Therefore, early recognition of symptoms and referral to an immunologist for a basic immune evaluation is required to select appropriate treatments. Therapies for primary immunodeficiency comprise immunoglobulin replacement, antibiotics, and, in severe cases, bone marrow transplantation. Treatment of immunodeficient patients with concomitant gastrointestinal disease can be challenging, and therapy with immunomodulators often is required for severe disease. This review aims to guide gastroenterologists in the diagnosis and treatment of patients with primary immunodeficiency. PMID:23501398

2012-08-01

As seven out of every ten patients with upper gastrointestinal malignancies (UGIM) are not eligible for curative treatment, life after diagnosis is characterised by a rapid deterioration and uncertainty. To accommodate these issues, we established a telephone hotline. In a two-year period, all patients evaluated for UGIM were given the hotline phone number. The hotline was staffed by either a nurse or a secretary, and subsequently the specialist in charge of the patient would return the call. All calls were registered in a prospective database. The following data were recorded: diagnosis, time from call to return call, problem and solution to the problem. A total of 477 patients were included, and 172 (36%) patients used the Hotline a total of 254 times. Of the 254 calls, 210 (83%) were returned the same day. A total of 104 (41%) calls were made due to elaborative questions and 89% of these were solved over the phone. Dysphagia was the problem in 51 cases which gave rise to an endoscopy in 86% of cases. Pain was the problem in 35. Overall, of the 254 calls, 152 (60%) problems were solved over the phone. Furthermore, 75 calls triggered a hospital visit and 27 calls led to the patient being referred for further examinations. The establishment of a telephone hotline was feasible and it was used by some patients. Most of the callers only made one call. Nearly all calls (96%) were returned the day after the initial call, at the latest. The problem pattern did not differ between disease groups apart from dysphagia in oesophageal cancer. We found that the hotline was an effective and inexpensive part of overall patient management. not relevant. not relevant.

Safety and Effectiveness of Mycophenolate in Systemic Sclerosis. A Systematic Review

PubMed Central

2015-01-01

Background Mycophenolate is increasingly being used in the rheumatic diseases. Its main adverse effects are gastrointestinal, myelosuppression, and infection. These may limit use in systemic sclerosis (SSc) since gastrointestinal involvement is common. The objective of this study is to evaluate gastrointestinal adverse events of mycophenolate in SSc. Secondarily we evaluated other adverse events, and the effectiveness of mycophenolate in skin and lung disease. Methods A literature search of Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL (inception-2013) was performed. Studies reporting use of mycophenolate in SSc patients, adverse events, modified Rodnan skin score (MRSS), forced vital capacity (FVC), or diffusing capacity of carbon monoxide (DLCO) were included. The primary outcome was gastrointestinal events occurring after the initiation of mycophenolate. Secondary safety outcomes included myelosuppression, infection, malignancy, and death after the initiation of mycophenolate. Results 617 citations were identified and 21 studies were included. 487 patients were exposed to mycophenolate. The mean disease duration ranged between 0.8-14.1 years. There were 18 deaths and 90 non-lethal adverse events. The non-lethal adverse events included 43 (47.7%) gastrointestinal events, 34 (26%) infections, 6 (5%) cytopenias and 2 (2%) malignancies. The most common gastrointestinal events included diarrhea (n=18 (14%)), nausea (n=12 (9%)), and abdominal pain (n=3 (2%)). The rate of discontinuation ranged between 8%-40%. Seven observational studies reported improvement or stabilization in FVC, and 5 studies report stabilization or improvement in MRSS. Conclusion Mycophenolate-associated gastrointestinal adverse events are common in SSc, but not severe enough to preclude its use. Observational data suggests mycophenolate may be effective in improving or stabilizing interstitial lung disease, and skin involvement. PMID:25933090

Fistulae between the colon and upper gastrointestinal tract are distressing and uncommon complications of malignancies involving this region. We report a case of a middle-aged man with a locally advanced and metastatic distal transverse colon malignancy who presented with a duodenocolic fistula proximal to the primary tumor and underwent palliative surgery. A 50-year-old Sri Lankan man presented to our hospital with a history of feculent vomiting of 1 week's duration preceded by worsening constipation and abdominal fullness of 2 months' duration. He also complained of anorexia and significant weight loss over the previous month. His physical examination was unremarkable except for his wasted appearance. Flexible sigmoidoscopy done at his local hospital had not revealed any abnormality in the left colon. Gastroduodenoscopy did not reveal fecal matter or any mucosal abnormalities in the stomach or duodenum. An abdominal contrast-enhanced computed tomographic scan showed a mid-to-distal transverse colonic tumor with a duodenocolic fistula proximal to the primary lesion. At laparotomy, he was found to have an unresectable, locally advanced mid transverse colon tumor with diffuse peritoneal and mesenteric deposits and mild ascites. Palliative end ileostomy and gastrojejunostomy were performed before closure. Histology from the malignant deposits revealed a well-differentiated adenocarcinoma. He made an uneventful recovery with good symptomatic relief. Malignant gastric or duodenocolic fistulae are uncommon complications of locally advanced colonic malignancies with direct invasion to the stomach or duodenum. Although the characteristic clinical presentation of feculent vomiting suggests the diagnosis, cross-sectional imaging is confirmative in addition to staging the disease. Management is guided by disease stage, nutritional status, and the general condition of the patient and ranges from extensive bowel resection including the fistula to palliative options.

Aspirin and omeprazole for secondary prevention of cardiovascular disease in patients at risk for aspirin-associated gastric ulcers.

García-Rayado, Guillermo; Sostres, Carlos; Lanas, Angel

2017-08-01

Cardiovascular disease is the most important cause of morbidity and mortality in the world and low-dose aspirin is considered the cornerstone of the cardiovascular disease prevention. However, low-dose aspirin use is associated with gastrointestinal adverse effects in the whole gastrointestinal tract. In this setting, co-therapy with a proton pump inhibitor is the most accepted strategy to reduce aspirin related upper gastrointestinal damage. In addition, some adverse effects have been described with proton pump inhibitors long term use. Areas covered: Low-dose aspirin related beneficial and adverse effects in cardiovascular system and gastrointestinal tract are reviewed. In addition, this manuscript summarizes current data on upper gastrointestinal damage prevention and adverse events with proton pump inhibition. Finally, we discuss the benefit/risk ratio of proton pump inhibitor use in patients at risk of gastrointestinal damage taking low-dose aspirin. Expert commentary: Nowadays, with the current available evidence, the combination of low-dose aspirin with proton pump inhibitor is the most effective therapy for cardiovascular prevention in patients at high gastrointestinal risk. However, further studies are needed to discover new effective strategies with less related adverse events.

Administrative healthcare databases are useful to investigate the epidemiology, health outcomes, quality indicators and healthcare utilisation concerning peptic ulcers and gastrointestinal bleeding, but the databases need to be validated in order to be a reliable source for research. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases, 9th Revision and 10th version (ICD-9 and ICD-10) codes for peptic ulcer and upper gastrointestinal bleeding diagnoses. MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched, using appropriate search strategies. We will include validation studies that used administrative data to identify peptic ulcer disease and upper gastrointestinal bleeding diagnoses or studies that evaluated the validity of peptic ulcer and upper gastrointestinal bleeding codes in administrative data. The following inclusion criteria will be used: (a) the presence of a reference standard case definition for the diseases of interest; (b) the presence of at least one test measure (eg, sensitivity, etc) and (c) the use of an administrative database as a source of data. Pairs of reviewers will independently abstract data using standardised forms and will evaluate quality using the checklist of the Standards for Reporting of Diagnostic Accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) 2015 statement. Ethics approval is not required given that this is a protocol for a systematic review. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide for researchers validating administrative healthcare databases to determine appropriate case definitions for peptic ulcer disease and upper gastrointestinal bleeding, as well as to perform outcome research using administrative healthcare databases of these conditions.

Conventional endoscopy for self-expandable metallic stent (SEMS) placement may be technically limited in long and tortuous strictures. Therefore, we analyzed the feasibility, safety and usefulness of ultrathin endoscopy (UTE)-guided SEMS placement. This study involved 24 patients with upper gastrointestinal obstruction and unsuccessful initial attempts to place SEMS using conventional endoscopy. After completely passing a UTE across the stricture, the UTE was withdrawn, leaving a guidewire placed via the working channel. Through-the-scope SEMS placement was done using a conventional endoscope inserted along the guidewire. The primary endpoints were assessed by technical/clinical success and stent patency duration. Stents were successfully placed at target locations in all but one case with a long tortuous stricture, with 95.8% (23/24) technical success. One week after stent placement, mean gastricoutlet obstruction score improved significantly from baseline (1.74 ± 0.62 and 0.33 ± 0.48, respectively; P < 0.001). Stent migration, restenosis, and fracture occurred in four (17.4%), six (26.1%), and one (4.3%) of 23 stents, respectively. Median stent patency duration was 79 days. Mean stent patency was significantly longer in patients who received palliative chemotherapy than in those who did not (122.9 ± 11.0 and 38.3 ± 4.6, respectively; P < 0.001). UTE guidance SEMS delivery can be a feasible and safe rescue treatment method for malignant upper gastrointestinal obstruction in cases of failed attempts to place SEMS using conventional endoscopy. Our result warrants a further study to define the efficacy of this method in difficult SEMS placement cases. © 2013 The Authors.

In adults, most intussusceptions develop from a lesion, usually a benign or malignant neoplasm, and can occur at any site in the gastrointestinal tract. Intussusception in the proximal gastrointestinal tract is uncommon, and gastro-gastric intussusception is extremely rare. We present a case of gastro-gastric intussusception secondary to a primary gastric lymphoma. An 82-year-old female patient presented with acute onset chest pain and vomiting. Abdominal CT revealed a gastro-gastric intussusception. We performed upper gastrointestinal endoscopy, revealing a large gastric mass invaginated into the gastric lumen and distorting the distal stomach. Uncomplicated gastric reposition was achieved with endoscopy of the distal stomach. Histological evaluation of the gastric mass revealed a diffuse large B cell lymphoma that was treated with chemotherapy.

Rare cause of upper gastrointestinal bleeding owing to hepatic cancer invasion: a case report.

Upper gastrointestinal bleeding refers to bleeding that arises from the gastrointestinal tract proximal to the ligament of Treitz. The primary reason for gastrointestinal bleeding associated with hepatocellular carcinoma is rupture of a varicose vein owing to pericardial hypotension. We report a rare case of gastrointestinal bleeding with hepatocellular carcinoma in a patient who presented with recurrent gastrointestinal bleeding. The initial diagnosis was gastric cancer with metastasis to the multiple lymph nodes of the lesser curvature. The patient underwent exploratory laparotomy, which identified two lesions in the gastric wall. Total gastrectomy and hepatic local excision was then performed. Pathological results indicated that the hepatocellular carcinoma had invaded the stomach directly, which was confirmed immunohistochemically. The patient is alive with a disease-free survival of 1 year since the surgery. Hepatocellular carcinoma with gastric invasion should be considered as a rare cause of upper gastrointestinal bleeding in hepatocellular carcinoma patients, especially with lesions located in the left lateral hepatic lobe. Surgery is the best solution.

Nutritional support in patients with gastrointestinal fistula.

Gastrointestinal fistulas (GIFs) arise as a complication of the surgical treatment of a number of malignant and non-malignant diseases. Fluid loss and electrolyte and nutritional imbalance are related to increased morbidity and mortality in these patients. A multidisciplinary approach under the leadership of the surgeon is essential for successful therapy. Because complication rates are higher in malnourished patients with fistulas, enteral or total parenteral nutritional (TPN) support should be initiated after the patient has been stabilized with respect to fluid loss, acid-base, and sepsis. Pharmacotherapy with somatostatin and octreotide has been shown to reduce fistula output and shorten closure time.

Palliative management of malignant upper urinary tract obstruction

Malignancies of the genitourinary tract are diagnosed with increased frequency compared to the past. Currently prostate and bladder cancer account for the majority of urological malignancies. While for prostate cancer recent developments in the management of local and metastatic disease are likely to lead the majority of patients to either cure from the disease or to longer survival time, for bladder cancer advanced disease will unfortunately lead to death within months. However, the common clinical scenario in both prostate and bladder cancer includes, in high incidence, upper urinary tract obstruction in the advanced stages of these malignancies. This coupled with the fact that average life expectancy in the western world is increasing, will result in a significant patient population with either advanced, non-curable disease or with problems related to the received therapeutic surgical or medical interventions. There is no doubt that in both circumstances the room and role of palliation therapy is increasing. The care of patients with advanced urologic malignancies requires a multi-disciplinary effort from physicians of many specialties under the guiding role of the treating urologist. This review focuses on currently available palliative therapeutic options for upper urinary tract obstruction in the setting of patients with advanced malignancies of the urinary tract, as recently significant advancements have been witnessed in this field.

Nodular lymphoid hyperplasia of the gastrointestinal tract is characterized by the presence of innumerable small discrete nodules involving a variable segment of the gastrointestinal tract. The association between nodular lymphoid hyperplasia and other benign and malignant diseases has been clearly described, with an increased risk of gastrointestinal tumours, namely gastrointestinal lymphoma. However, the association with extraintestinal lymphoma seems extremely rare. The authors present a clinical case of a patient with nodular lymphoid hyperplasia of the small and large intestine that subsequently developed an extraintestinal lymphoma (diffuse large B-cell lymphoma).

A 70-year-old man presented with complaints of difficult urination, perineal pain and lassitude. An enlarged, hard and nodular prostate was palpable on digital rectal examination. Needle biopsy of the prostate was performed, which revealed diffuse large B-cell non-Hodgkin's lymphoma by immunohistochemical studies. Right internal and external iliac nodes were swollen on computed tomographic scan (CT) of the pelvis. No abnormal finding was seen on abdominal CT, upper gastrointestinal fiberscopy and bone marrow histology. Therefore, the disease was classified into the clinical stage II according to Ann Arbor's criteria. The patient achieved complete response (CR) to five cycles of combination chemotherapy, CHOP, and survives more than two years without recurrence. Primary malignant lymphoma of the prostate is a rare prostatic malignancy. Only 22 Japanese cases with primary prostatic lymphoma have been reported to our knowledge. In 23 cases including ours the majority of the patients were older than 60 years, and their histopathology was mostly diffuse lymphoma, which belongs to intermediate grade of non-Hodjkin's lymphoma according to the Working Formulation's Classification. Nineteen out of 23 cases (83%) were divided into localized stage i.e. stage I or II. In these reports, three of five cases treated with either radical prostatectomy or radiotherapy alone resulted in death or progressive disease. On the other hand, 11 out of 16 cases (69%) who received chemotherapy alone or with other therapy obtained CR. Primary lymphoma of prostate has previously been considered to have a poor prognosis. Our results, however, suggest that patients with this malignancy respond well to combined chemotherapy, and could possibly be cured when the disease is confined to the localized stage.

Evaluation and treatment of iron deficiency anemia: a gastroenterological perspective.

PubMed

Zhu, Amy; Kaneshiro, Marc; Kaunitz, Jonathan D

2010-03-01

A substantial volume of the consultations requested of gastroenterologists are directed towards the evaluation of anemia. Since iron deficiency anemia often arises from bleeding gastrointestinal lesions, many of which are malignant, establishment of a firm diagnosis usually obligates an endoscopic evaluation. Although the laboratory tests used to make the diagnosis have not changed in many decades, their interpretation has, and this is possibly due to the availability of extensive testing in key populations. We provide data supporting the use of the serum ferritin as the sole useful measure of iron stores, setting the lower limit at 100 microg/l for some populations in order to increase the sensitivity of the test. Trends of the commonly obtained red cell indices, mean corpuscular volume, and the red cell distribution width can provide valuable diagnostic information. Once the diagnosis is established, upper and lower gastrointestinal endoscopy is usually indicated. Nevertheless, in many cases a gastrointestinal source is not found after routine evaluation. Additional studies, including repeat upper and lower endoscopy and often investigation of the small intestine may thus be required. Although oral iron is inexpensive and usually effective, there are many gastrointestinal conditions that warrant treatment of iron deficiency with intravenous iron.

The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. Conclusion The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or endoscopic evidence of upper gastrointestinal disorder and gastroesophageal reflux disease was found in significantly higher proportion of the asthmatics as compared to the controls. Clinically silent gastroesophageal reflux disease was however seen in both control and asthmatic groups equally with a lower prevalence. PMID:26557556

To report a rare case of periorbital emphysema concurrent with cervicofacial and mediastinal emphysema in an elderly woman who underwent upper gastrointestinal endoscopy for chronic liver disease. An elderly woman with decompensated chronic liver disease presented with features of periorbital, facial, and mediastinal emphysema, characterized with crepitant swelling over the right periorbital area, face, neck, and mediastinum after undergoing upper gastrointestinal endoscopy. There was no history of trauma or Valsalva maneuver. Ocular findings were stable with no evidence of orbital compartmental syndrome. Urgent computed tomography scans of the orbit and chest were performed, and emergency systemic treatment with nasogastric decompression and antibiotics was initiated. However, she suddenly collapsed and succumbed despite all resuscitative efforts. Our case demonstrates that periorbital emphysema can occur following procedures such as upper gastrointestinal endoscopy, in the eyes without history of local trauma. This complication should be suspected especially if there is associated cervicofacial and mediastinal emphysema. Subcutaneous emphysema is usually self-resolving; however, extension of air into deeper planes can cause dangerous complications such as blindness due to orbital emphysema or mortality due to mediastinal emphysema. Hence, prompt diagnosis and urgent intervention are crucial to avoid vision and life threatening complications.

To determine the prognostic risk factors of gastrointestinal bleeding in emergency department cases. The trial was a retrospective single-center study involving 600 patients over 18-years-old and carried out with approval by the Institutional Ethics Committee. Patient data included demographic characteristics, symptoms at admission, past medical history, vital signs, laboratory results, endoscopy and colonoscopy results, length of hospital stay, need of intensive care unit (ICU) admission, and mortality. Mortality rate was the principal endpoint of the study, while duration of hospital stay, required interventional treatment, and admission to the ICU were secondary endpoints. The mean age of patients was 61.92-years-old. Among the 600 total patients, 363 (60.5%) underwent upper gastrointestinal endoscopy and the most frequent diagnoses were duodenal ulcer (19.2%) and gastric ulcer (12.8%). One-hundred-and-fifteen (19.2%) patients required endoscopic treatment, 20 (3.3%) required surgical treatment, and 5 (0.8%) required angiographic embolization. The mean length of hospital stay was 5.21 ± 5.85 d. The mortality rate was 6.3%. The ICU admission rate was 5.3%. Patients with syncope, higher blood glucose levels, and coronary artery disease had significantly higher ICU admission rates (P = 0.029, P = 0.043, and P = 0.002, respectively). Patients with low thrombocyte levels, high creatinine, high international normalized ratio, and high serum transaminase levels had significantly longer hospital stay (P = 0.02, P = 0.001, P = 0.019, and P = 0.005, respectively). Patients who died had significantly higher serum blood urea nitrogen and creatinine levels (P = 0.016 and P = 0.038), and significantly lower mean blood pressure and oxygen saturation (P = 0.004 and P = 0.049). Malignancy and low Glasgow coma scale (GCS) were independent predictive factors of mortality. Prognostic factors for gastrointestinal bleeding in emergency room cases are malignancy, hypotension on admission, low GCS, and impaired kidney function.

Cardioprotective aspirin users and their excess risk of upper gastrointestinal complications.

To balance the cardiovascular benefits from low-dose aspirin against the gastrointestinal harm caused, studies have considered the coronary heart disease risk for each individual but not their gastrointestinal risk profile. We characterized the gastrointestinal risk profile of low-dose aspirin users in real clinical practice, and estimated the excess risk of upper gastrointestinal complications attributable to aspirin among patients with different gastrointestinal risk profiles. To characterize aspirin users in terms of major gastrointestinal risk factors (i.e., advanced age, male sex, prior ulcer history and use of non-steroidal anti-inflammatory drugs), we used The General Practice Research Database in the United Kingdom and the Base de Datos para la Investigación Farmacoepidemiológica en Atención Primaria in Spain. To estimate the baseline risk of upper gastrointestinal complications according to major gastrointestinal risk factors and the excess risk attributable to aspirin within levels of these factors, we used previously published meta-analyses on both absolute and relative risks of upper gastrointestinal complications. Over 60% of aspirin users are above 60 years of age, 4 to 6% have a recent history of peptic ulcers and over 13% use other non-steroidal anti-inflammatory drugs. The estimated average excess risk of upper gastrointestinal complications attributable to aspirin is around 5 extra cases per 1,000 aspirin users per year. However, the excess risk varies in parallel to the underlying gastrointestinal risk and might be above 10 extra cases per 1,000 person-years in over 10% of aspirin users. In addition to the cardiovascular risk, the underlying gastrointestinal risk factors have to be considered when balancing harms and benefits of aspirin use for an individual patient. The gastrointestinal harms may offset the cardiovascular benefits in certain groups of patients where the gastrointestinal risk is high and the cardiovascular risk is low.

Experimental evidence from the past years highlights a key role for the intestinal microbiota in inflammatory and malignant gastrointestinal diseases. Diet exhibits a strong impact on microbial composition and provides risk for developing colorectal carcinoma (CRC). Large metagenomic studies in human CRC associated microbiome signatures with the colorectal adenoma-carcinoma sequence, suggesting a fundamental role of the intestinal microbiota in the evolution of gastrointestinal malignancy. Basic science established a critical function for the intestinal microbiota in promoting tumorigenesis. Further studies are needed to decipher the mechanisms of tumor promotion and microbial co-evolution in CRC, which may be exploited therapeutically in the future. Copyright © 2018 Elsevier Inc.

Sleep specialists usually do not pay much attention to the upper airway in patients who snore, because they can make the diagnosis of sleep-disordered breathing without performing nasopharyngeal endoscopy if they have the Epworth Sleepiness Scale scores and the results of polysomnography. The purpose of this study was to determine the prevalence of benign and malignant tumors and cysts in the upper airway in patients who snore. A retrospective multicenter trial was performed in 4 sleep laboratories. Adult male and female patients whose chief complaint on their first visit was witnessed snoring were enrolled in this study. All of the patients were evaluated by otolaryngologists using nasopharyngeal endoscopy to detect organic diseases in the upper airway. Among 2,923 patients, 2 patients had malignant tumors, 5 had benign tumors, and 2 had cysts in the upper airway. The prevalence of upper airway benign and malignant tumors and cysts among adult male and female patients was 0.24%. Routine detailed nasopharyngeal endoscopy should be carried out in each institution so as not to overlook organic diseases in the upper airway among patients who snore.

Gastrointestinal lymphomas represent up to 10% of gastrointestinal malignancies and about one third of non-Hodgkin lymphomas. The most prominent histologies are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma. However, the gastrointestinal tract can be the site of rarer lymphoma subtypes as a primary or secondary localization. Due to their rarity and the multifaceted histology, an endoscopic classification has not been validated yet. This review aims to analyze the endoscopic presentation of rare gastrointestinal lymphomas from disease diagnosis to follow-up, according to the involved site and lymphoma subtype. Existing, new and emerging endoscopic technologies have been examined. In particular, we investigated the diagnostic, prognostic and follow-up endoscopic features of T-cell and natural killer lymphomas, lymphomatous polyposis and mantle cell lymphoma, follicular lymphoma, plasma cell related disease, gastrointestinal lymphomas in immunodeficiency and Hodgkin’s lymphoma of the gastrointestinal tract. Contrarily to more frequent gastrointestinal lymphomas, data about rare lymphomas are mostly extracted from case series and case reports. Due to the data paucity, a synergism between gastroenterologists and hematologists is required in order to better manage the disease. Indeed, clinical and prognostic features are different from nodal and extranodal or the bone marrow (in case of plasma cell disease) counterpart. Therefore, the approach should be based on the knowledge of the peculiar behavior and natural history of disease. PMID:26265987

Summary Weekly bisphosphonates are the primary agents used to treat osteoporosis. Although these agents are generally well tolerated, serious gastrointestinal adverse events, including hospitalization for gastrointestinal bleed, may arise. We compared the gastrointestinal safety between weekly alendronate and weekly risedronate and found no important difference between new users of these agents. Introduction Weekly bisphosphonates are the primary agents prescribed for osteoporosis. We examined the comparative gastrointestinal safety between weekly bisphosphonates. Methods We studied new users of weekly alendronate and weekly risedronate from June 2002 to August 2005 among enrollees in a state-wide pharmaceutical benefit program for seniors. Our primary outcome was hospitalization for upper gastrointestinal bleed. Secondary outcomes included outpatient diagnoses for upper gastrointestinal disease, symptoms, endoscopic procedures, use of gastroprotective agents, and switching between therapies. We used Cox proportional hazard models to compare outcomes between agents within 120 days of treatment initiation, adjusting for propensity score quintiles. We also examined composite safety outcomes and stratified results by age and prior gastrointestinal history. Results A total of 10,420 new users were studied, mean age=79 years (SD, 6.9), and 95% women. We observed 31 hospitalizations for upper gastrointestinal bleed (0.91 per 100 person-years) within 120 days of treatment initiation. Adjusting for covariates, there was no difference in hospitalization for upper gastrointestinal bleed among those treated with risedronate compared with alendronate (HR, 1.12; 95%CI, 0.55 to 2.28). Risedronate switching rates were lower; otherwise, no differences were observed for secondary or composite outcomes. Conclusions We found no important difference in gastrointestinal safety between weekly oral bisphosphonates. PMID:19266138

Because the effect of physician supply on utilization remains controversial, literature based on non-Medicare populations is sparse, and a physician supply expansion is under way, the potential for physician-induced demand across diverse populations is important to understand. A substantial proportion of gastrointestinal endoscopies may be inappropriate. The authors analyzed the impact of physician supply, practice patterns, and clinical history on esophagogastroduodenoscopy (EGD, defined as discretionary) among patients hospitalized with lower gastrointestinal bleeding (LGIB). Among 34,344 patients hospitalized for LGIB from 2004 to 2009, 43.1% and 21.3% had a colonoscopy or EGD, respectively, during the index hospitalization or within 6 months after. Linking to the Dartmouth Atlas via patients' hospital referral region, gastroenterologist density and hospital care intensity (HCI) index were ascertained. Adjusting for age, gender, comorbidities, and race/education indicators, the association of gastroenterologist density, HCI index, and history of upper gastrointestinal disease with EGD was estimated using logistic regression. EGD was not associated with gastroenterologist density or HCI index, but was associated with a history of upper gastrointestinal disease (OR 2.30; 95% CI 2.17-2.43), peptic ulcer disease (OR 4.82; 95% CI 4.26-5.45), and liver disease (OR 1.34; 95% CI 1.18-1.54). Among patients hospitalized with LGIB, large variation in gastroenterologist density did not predict EGD, but relevant clinical history did, with association strengths commensurate with risk for upper gastrointestinal bleeding. In the scenario studied, no evidence was found that specialty physician supply increases will result in more discretionary care within commercially insured populations.

A Fibreoptic endoscopic study of upper gastrointestinal bleeding at Bugando Medical Centre in northwestern Tanzania: A retrospective review of 240 cases

Background Upper gastrointestinal (GI) bleeding is recognized as a common and potentially life-threatening abdominal emergency that needs a prompt assessment and aggressive emergency treatment. A retrospective study was undertaken at Bugando Medical Centre in northwestern Tanzania between March 2010 and September 2011 to describe our own experiences with fibreoptic upper GI endoscopy in the management of patients with upper gastrointestinal bleeding in our setting and compare our results with those from other centers in the world. Findings A total of 240 patients representing 18.7% of all patients (i.e. 1292) who had fibreoptic upper GI endoscopy during the study period were studied. Males outnumbered female by a ratio of 2.1:1. Their median age was 37 years and most of patients (60.0%) were aged 40 years and below. The vast majority of the patients (80.4%) presented with haematemesis alone followed by malaena alone in 9.2% of cases. The use of non-steroidal anti-inflammatory drugs, alcohol and smoking prior to the onset of bleeding was recorded in 7.9%, 51.7% and 38.3% of cases respectively. Previous history of peptic ulcer disease was reported in 22(9.2%) patients. Nine (3.8%) patients were HIV positive. The source of bleeding was accurately identified in 97.7% of patients. Diagnostic accuracy was greater within the first 24 h of the bleeding onset, and in the presence of haematemesis. Oesophageal varices were the most frequent cause of upper GI bleeding (51.3%) followed by peptic ulcers in 25.0% of cases. The majority of patients (60.8%) were treated conservatively. Endoscopic and surgical treatments were performed in 30.8% and 5.8% of cases respectively. 140 (58.3%) patients received blood transfusion. The median length of hospitalization was 8 days and it was significantly longer in patients who underwent surgical treatment and those with higher Rockall scores (P < 0.001). Rebleeding was reported in 3.3% of the patients. The overall mortality rate of 11.7% was significantly higher in patients with variceal bleeding, shock, hepatic decompensation, HIV infection, comorbidities, malignancy, age > 60 years and in patients with higher Rockall scores and those who underwent surgery (P < 0.001). Conclusion Oesophageal varices are the commonest cause of upper gastrointestinal bleeding in our environment and it is associated with high morbidity and mortality. The diagnostic accuracy of fibreoptic endoscopy was related to the time interval between the onset of bleeding and endoscopy. Therefore, it is recommended that early endoscopy should be performed within 24 h of the onset of bleeding. PMID:22537571

Transplantation results in a 5-time elevated risk for a variety of malignancies (Kaposi sarcoma, skin, liver, lung, gastrointestinal cancer). A patient's risk for malignancies could be of particular interest for the follow-up programs of patients and risk adaption after kidney transplantation. The aim of this study was to identify independent risk factors for de novo malignancies in women after renal transplantation. This is a multicenter transversal study, conducted at the Medical University of Vienna and Hospital Rudolfstiftung, Vienna, Austria. We included female kidney graft recipients who were transplanted between 1980 and 2012 and followed-up at our institutions (N = 280). Clinical data of patients were extracted from hospital charts and electronic patient files. Patients were interviewed using a standardized questionnaire regarding their medical history, history of transplantation, and malignant diseases. Detailed information about present and past immunosuppressive regimens, rejection episodes and therapies, renal graft function, and information about primary disease was obtained. Diagnostic work-up and/or surgical exploration was performed if any presence of malignancy was suspected during routine follow-up. Histological specimens were obtained from all patients. the presence of de novo malignancy after kidney transplantation. Two hundred sixty-two women were included for statistical analysis. Median (interquartile range) follow-up period after transplantation was 101.1 (27.3-190.7) months. Thirty-two patients (12.2%) developed a malignancy: dermatologic malignancies (5.7%), breast cancer (3.4%), cervical cancer (0.8%), lung cancer (0.4%), gastrointestinal malignancies (1.5%), vulvar cancer (0.4%), and unclassified malignancies (1.9%). Median (interquartile range) time to malignancy after transplantation was 185.9 (92.0-257.6) months. Cumulative cancer rates were 4.9% (1 year), 14.4% (3 years), 16.4% (5 years), and 21.8% (10 years). Second transplantations were identified as independent risk factor for development of malignancy after transplantation. Long-term risk of developing a malignancy after kidney transplantation is high, which might justify a follow-up of more than 10 years.

Very few data are available about Zn in gastrointestinal fluids in humans. To obtain data in one such fluid Zn was measured in plasma and gastric fluid, obtained by direct visual aspiration through an endoscope placed into the gastric fundus, in 36 subjects with normal gastrointestinal mucosa (N) and in 36 patients with the following upper gastrointestinal pathology confirmed by endoscopy: 13 with esophagitis (E), 9 with gastritis (G) and 14 with duodenal ulcer disease (DU). Plasma and gastric fluid Zn were estimated by flame atomic absorption spectrophotometry. Mean plasma Zn was significantly lower than normal in patients with Emore » (N, 87 +/- 2 ..mu..g/dl, M +/- SEM; E, 75 +/- 4, p < 0.01) but plasma values were similar to normal in the other patient groups (G, 89 +/- 4; DU, 87 +/- 2). Mean gastric fluid zinc in G was significantly higher than in normal subjects (G, 664 +/- 159 ..mu..g/L; N, 360 +/- 43, p < 0.02) but not significantly different from normal in patients with DU or E (DU, 402 +/- 76; E, 307 +/- 55). Mean gastric fluid Zn in women with DU was approximately 45% higher than in men with DU, although it was 17% lower in normal women than in normal men. Compared to other normal tissues gastric fluid Zn is about 1/3 that in serum and about 3 times that in saliva. These results indicate that Zn in plasma and gastric fluid is altered in some upper gastrointestinal diseases.« less

To retrospectively evaluate the incidence, predictive factors, and interventional management of food impaction after expandable metallic stent placement in patients with obstruction of the esophagus or upper gastrointestinal tract caused by benign or malignant disease. Between March 1993 and March 2010, 1,360 patients (1,029 men, 331 women; age range, 21-89 y; mean age, 61 y) underwent fluoroscopically guided stent placement for dysphagia caused by esophageal or gastrointestinal tract strictures. Five types of covered expandable metal stents were used, including four types of esophageal stents (types A-D) and one type of gastroduodenal stent (type E), with types A, B, C, D, and E stents used in 180, 60, 90, 432, and 598 patients, respectively. Multivariate analysis was performed to evaluate factors predictive of food impaction. Food impaction occurred in 41 of 1,360 patients (3.0%). The food impaction rates for types A, B, C, D, and E stents were 0.6%, 1.7%, 1.1%, 3.2%, and 4.0%, respectively. Multivariate analysis showed that stent length was an independent predictor of food impaction (odds ratio, 0.839; P = .012). Of the 41 patients with food impaction, 23 underwent endoscopic management, 12 underwent fluoroscopically guided management, and six did not require management because impacted food spontaneously passed through the stent. The overall food impaction rate was 3.0%, with multiple logistic regression analysis showing that shorter stent length was the only significant predictor of food impaction. Food impaction can be managed by endoscopic or fluoroscopically guided removal or placement of a second stent. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

Protons pump inhibitor treatment and lower gastrointestinal bleeding: Balancing risks and benefits.

PubMed

Lué, Alberto; Lanas, Angel

2016-12-28

Proton pump inhibitors (PPIs) represent a milestone in the treatment of acid-related diseases, and are the mainstay in preventing upper gastrointestinal bleeding in high-risk patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin. However, this beneficial effect does not extend to the lower gastrointestinal tract. PPIs do not prevent NSAID or aspirin-associated lower gastrointestinal bleeding (LGB). PPIs may increase both small bowel injury related to NSAIDs and low-dose aspirin treatment and the risk of LGB. Recent studies suggested that altering intestinal microbiota by PPIs may be involved in the pathogenesis of NSAID-enteropathy. An increase in LGB hospitalization rates may occur more frequently in older patients with more comorbidities and are associated with high hospital resource utilization, longer hospitalization, and increased mortality. Preventive strategies for NSAID and aspirin-associated gastrointestinal bleeding should be directed toward preventing both upper and lower gastrointestinal damage. Future research should be directed toward identifying patients at low-risk for gastrointestinal events associated with the use of NSAIDs or aspirin to avoid inappropriate PPI prescribing. Alternatively, the efficacy of new pharmacologic strategies should be evaluated in high-risk groups, with the aim of reducing the risk of both upper and lower gastrointestinal bleeding in these patients.

This is a retrospective analysis of interventional embolisation performed with catheter angiography in 29 patients with upper gastrointestinal bleeding in the setting of a secondary care hospital. From April 2007 to February 2013, 29 patients with upper gastrointestinal bleeding underwent endovascular diagnostics and treatment. The diagnosis was established by endoscopy, computed tomography or clinically based on a significant decrease in hemoglobin. Transcatheter arterial embolisation was performed with coils, liquid embolic agents, and particles. The technical and clinical outcomes were assessed by postinterventional endoscopy, hemoglobin concentrations, number of necessary transfusions, or surgical interventions, as well as by post-interventional mortality within 28 days after the procedure. Selective angiographic embolisation in upper gastrointestinal bleeding was primarily successful technically and clinically in 22 of 29 patients. In 4/29 cases an angiographic reintervention was performed, which was successful in 3 cases. In 3 cases of primarily technically unsuccessful procedures reintervention was not attempted. No catheterisation-related complications were recorded. Peri-interventional mortality was 31%, but only 2 of these patients died due to uncontrolled massive bleeding, whereas the lethal outcome in the other 7 patients was due to their underlying diseases. Transcatheter arterial embolisation is an effective and rapid method in the management of upper gastrointestinal bleeding. Radiological endovascular interventions may considerably contribute to reduced mortality in GI bleeding by avoiding a potential surgical procedure following unsuccessful endoscopic treatment. The study underlines the importance of the combination of interventional endoscopy with interventional radiology in secondary care hospitals for patient outcome in complex and complicated upper gastrointestinal bleeding situations. © Georg Thieme Verlag KG Stuttgart · New York.

Nuclear factor kappa B role in inflammation associated gastrointestinal malignancies

Nuclear factor kappa B (NF-κB) has an established role in the regulation of innate immunity and inflammation. NF-κB is also involved in critical mechanisms connecting inflammation and cancer development. Recent investigations suggest that the NF-κB signaling cascade may be the central mediator of gastrointestinal malignancies including esophageal, gastric and colorectal cancers. This review will explore NF-κB’s function in inflammation-associated gastrointestinal malignancies, highlighting its oncogenic contribution to each step of carcinogenesis. NF-κB’s role in the inflammation-to-carcinoma sequence in gastrointestinal malignancies warrants stronger emphasis upon targeting this pathway in achieving greater therapeutic efficacy.

Study of the immune system mechanisms in chronic catarrhal gingivitis in children with gastrointestinal pathology was performed in 102 children (49 with chronic gastritis and duodenitis and 53 with no signs of gastrointestinal pathology). Forty-eight children with healthy periodontium constituted control group. Generalized chronic catarrhal gingivitis in children with gastroduodenal pathology is characterized by intense humoral response by simultaneous T-cell immunity suppression. Detection of high serum titers of circulating immune complexes in patients with chronic catarrhal gingivitis suggests a role of immune response in the pathogenesis of periodontal disease increases with concomitant diseases of the upper gastrointestinal tract.

Gastrointestinal stromal tumor (GIST) is a rare cancer in gastrointestinal carcinomas and has been widely known as a curable disease among all the digestive tumors. However, early detection of malignant potential in patients with GIST has still been a huge challenge all around the world. CT, MRI, and F-18 FDG PET are all considered as good tests for diagnosing malignant GIST efficiently, but no recommended suggestions presents which test among the 3 is the prior one in detecting the malignant potential of GIST. We perform this study to assess the accuracy between CT, MRI, and F-18 FDG PET through network meta-analysis method, and to rank these tests. PubMed, EMBASE.com, CNKI, and CBM databases will be searched without search date and language restrictions. We will include diagnostic tests which assessed the accuracy of CT, MRI, and F-18 FDG PET in detecting the malignant potential of GIST. The risk of bias in each study will be independently assessed as low, moderate, or high using criteria adapted from Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). Meta-analysis will be performed using STATA 12.0 and R 3.4.1 software. The competing diagnostic tests will be ranked by a superiority index. This study is ongoing, and will be submitted to a peer-reviewed journal for publication. This study will provide a comprehensive evidence summary of CT, MRI, and F-18 FDG PET in detecting the malignant potential of GIST.

To study hospital mortality associated with upper gastrointestinal hemorrhages due to variceal bleeding in the department of hepatology and gastroenterology at the Lome Campus University Hospital. This retrospective cross-sectional and analytic study examined the 55 patients admitted for variceal bleeding on upper endoscopies during the 3-year period from January 1, 2008, through December 31, 2010. These patients accounted for 4.1% of all hospitalizations during the study period in the department. Their average age was 35 years, and their sex-ratio 4. A history of chronic liver disease was found in 65.5%. Liver cirrhosis was the principal cause of the esophageal varices, complicated by hepatocellular carcinoma in 30.9% of them. The mortality rate was 25.5% and was not related to the cause of portal hypertension. All the patients with a recurrence of bleeding died. Mortality was associated with jaundice. Blood transfusion did not significantly improve the prognosis. the mortality rate among patients with upper gastrointestinal hemorrhage linked to variceal bleeding is high in our unit. The prevention of hepatitis virus B is important because it is the main cause of chronic liver disease causing portal hypertension in our department.

Dysphagia results from impeded transport of liquids, solids, or both from the pharynx to the stomach. Among the malignant lesions, carcinoma of oesophagus is the commonest cause. Our objective was to find out the frequency of different endoscopic lesions and outcome of the endoscopic therapeutic interventions in patients presenting with dysphagia. This descriptive study was conducted at Department of Gastroenterology, Military Hospital Rawalpindi from June 2008 to May 2009. Patients of dysphagia after their consent were interviewed about the symptoms. Relevant biochemical investigations were done. Barium swallow and upper Gastrointestinal (GI) Endoscopy were carried out. Benign strictures were dilated with Savary Gilliard Dilators. Malignant strictures were further evaluated to decide treatment plan. In patients considered to have oesophageal dysmotility, pressure manometery was done before specific therapy. Seventy nine patients were enrolled. Twenty-five had malignant strictures, out of those commonest was adenocarcinoma 14 (56%). Twenty-nine had benign strictures the commonest being Gastro-oesophageal Reflux Disease (GERD) related peptic stricture 9 (31%). Fifteen had oesophageal dysmotility, and achalasia was present in 10 out of them. After evaluation 12 out of 25 patients with malignant strictures were considered fit for surgery. Self-expanding metal stents (SEMS) were passed in 5. All benign strictures were dilated with Savary-Gillard dilators. Pneumatic balloon dilation was done in patients of achalasia. The commonest malignant lesion resulting in dysphagia was adenocarcinoma while in benign it was GERD related peptic stricture. Achalasia was most frequent in oesophageal motility disorders. Standard of treatment for early oesophageal malignancy is surgical resection. SEMS is a reliable way to allay dysphagia in inoperable cases. Savary Gillard dilatation in benign, and pneumatic balloon achalasia dilatations are effective ways of treatment.

Systematic analyses of gender effects in gastrointestinal malignancies are currently lacking, partly because sex and gender have not been used as stratification criteria in major studies on the topic. It is, however, indisputable that gastrointestinal tumours differ in risk factors, incidence and prognosis between the genders. This review summarises the most important findings on differences related to biological sex and sociocultural gender and discusses anatomic specifics with immediate significance for surgical interventions. Epidemiological differences in upper gastrointestinal malignancies are most prominent in regard to histological subtypes, directly affecting diagnostics, therapy, and prognosis. Women have a better prognosis in many of these tumour subtypes. For colorectal carcinoma, sex hormones, specifically oestrogens, appear to play a distinct role in tumourigenesis. Histopathological analysis of the expression of oestrogen receptor beta (ERβ) in the tumour tissue has attracted interest since it was shown that women with low ERβ expression have a better prognosis than men with comparable ERβ status. Data on the higher incidence of right-sided colon carcinoma and non-polypoid neoplasms in women could lead to improved screening programmes. Men and women cite differing reasons for avoidance of screening colonoscopies, thus gender specific approaches could improve colon cancer prevention programmes. Data on differing bioavailability of 5-fluorouracil between the genders are useful to minimise adverse effects of chemotherapy and should be accounted for in dosage. Further systematic analysis of gender effects on gastrointestinal tumours is warranted and would be a substantial step towards personalised oncological surgery.

Non-specific gastrointestinal features: Could it be Fabry disease?

Non-specific gastrointestinal symptoms, including pain, diarrhoea, nausea, and vomiting, can be the first symptoms of Fabry disease. They may suggest more common disorders, e.g. irritable bowel syndrome or inflammatory bowel disease. The confounding clinical presentation and rarity of Fabry disease often cause long diagnostic delays and multiple misdiagnoses. Therefore, specialists involved in the clinical evaluation of non-specific upper and lower gastrointestinal symptoms should recognize Fabry disease as a possible cause of the symptoms, and should consider Fabry disease as a possible differential diagnosis. When symptoms or family history suggest Fabry disease, in men, low alpha-galactosidase A enzyme levels, and in women, specific Fabry mutations confirm the diagnosis. In addition to symptomatic treatments, disease-specific enzyme replacement therapy with recombinant human alpha-galactosidase A enzyme or chaperone therapy (migalastat) in patients with amenable mutations can improve the disease, including gastrointestinal symptoms, and should be initiated as early as possible after Fabry disease has been confirmed; starting enzyme replacement therapy at as young an age as possible after diagnosis improves long-term clinical outcomes. Improved diagnostic tools, such as a modified gastrointestinal symptom rating scale, may facilitate diagnosing Fabry disease in patients with gastrointestinal symptoms of unknown cause and thus assure timely initiation of disease-specific treatment.

Gastric polyps are usually found incidentally during upper gastrointestinal endoscopic examinations. These polyps are generally benign, with hyperplasia being the most common. While gastric polyps are often asymptomatic, they can cause gastric outlet obstruction. A 64 years-old female patient presented to our polyclinic with a history of approximately 2 months of weakness, occasional early nausea, vomiting after meals and epigastric pain. A polypoid lesion of approximately 25mm in diameter was detected in the antral area of the stomach, which prolapsed through the pylorus into the duodenal bulbus, and subsequently caused gastric outlet obstruction, as revealed by upper gastrointestinal endoscopy of the patient. The polyp was retrieved from the pyloric canal into the stomach with the aid of a tripod, and snare polypectomy was performed. Currently, widespread use of endoscopy has led to an increase in the frequency of detecting hyperplastic polyps. While most gastric polyps are asymptomatic, they can cause iron deficiency anemia, acute pancreatitis and more commonly, gastric outlet obstruction because of their antral location. Although there are no precise principles in the treatment of asymptomatic polyps, polyps >5mm should be removed due to the possibility of malignant transformation. According to the medical evidence, polypectomy is required for gastric hyperplastic polyps because of the risks of complication and malignancy. These cases can be successfully treated endoscopically.

Background Childhood cancer survivors develop gastrointestinal malignancies more frequently and at a younger age than the general population, but risk factors for their development have not been well characterized. Objective To determine the risk and associated risk factors for gastrointestinal subsequent malignant neoplasms (SMN) in childhood cancer survivors. Design Retrospective cohort study. Setting The Childhood Cancer Survivor Study, a multi-center study of childhood cancer survivors diagnosed between 1970 and 1986. Patients 14,358 survivors of a malignancy diagnosed at < 21 years who had survived for 5 or more years from initial diagnosis. Measurements Standardized incidence ratios (SIR) for gastrointestinal SMN were calculated using age-specific population data. Multivariate Cox regression models identified associations between risk factors and gastrointestinal SMN development. Results At median follow-up of 22.8 years (range: 5.5-30.2), 45 gastrointestinal malignancies were identified. Gastrointestinal SMN risk was 4.6-fold higher in childhood cancer survivors than the general population (95% confidence interval [CI]: 3.5-6.1). Colorectal cancer SIR was 4.2 (95% CI: 2.8-6.3). The highest gastrointestinal SMN risk was associated with abdominal radiation (SIR=11.2, 95% CI: 7.6-16.4). However, survivors not exposed to radiation had a significantly increased risk (SIR=2.4, 95% CI-1.4-3.9). In addition to abdominal radiation, high dose procarbazine (RR=3.2, 95% CI 1.1-9.4) and platinum drugs (RR 7.6, 95% CI: 2.3-25.5) independently increased the gastrointestinal SMN risk. Limitations This cohort has not yet attained an age at which gastrointestinal malignancy risk is greatest. Conclusions Childhood cancer survivors, particularly those exposed to abdominal radiation, are at increased risk for gastrointestinal SMN. These findings suggest that surveillance of at-risk childhood cancer survivors should commence at a younger age than recommended for the general population. PMID:22665813

An 88-year-old woman on long-term intravitreal bevacizumab presented with acute gastrointestinal hemorrhage. She was stabilized and underwent nonrevealing upper endoscopy. She continued to require intermittent blood transfusions, and resulting computed tomography of the abdomen revealed an aortoduodenal fistula. The patient was undergoing treatment for her macular degeneration with intravitreal bevacizumab, an angiogenesis inhibitor frequently used to treat solid organ malignancies. Systemic administration has been associated with serious adverse events, including gastrointestinal hemorrhage, perforation, and fistula formation. Intravitreal bevacizumab has been used off-label to treat macular degeneration, but data on the safety of this therapy are limited. Given her lack of other risk factors, the authors postulate a potential association between intravitreal bevacizumab and aortoduodenal fistula formation in this patient.

Duodenal bulb adenocarcinoma is an extremely rare malignancy in the alimentary tract which has a low incidence rate and nonspecific symptoms. It is difficult to diagnose early, and the misdiagnosis rate is high. CT, MRI, upper gastrointestinal endoscopy, and other advanced imaging modalities should be combined to make a comprehensive evaluation. The diagnostic confirmation of this tumor type mainly depends on the pathological examination. The combination of surgery with other treatment modalities is effective. A review of reports on duodenal bulb adenocarcinoma with chemotherapy revealed 6 cases since 1990. However, there are few reports on neoadjuvant chemotherapy for the disease. In this report, preoperative S-1 in combination with oxaliplatin neoadjuvant chemotherapy achieved a complete pathological response in the treatment of duodenal bulb adenocarcinoma. Neoadjuvant chemotherapy shows a better clinical efficacy in the treatment of duodenal bulb adenocarcinoma, but its value needs to be further verified. © 2017 S. Karger AG, Basel.

[Late complications of liver cirrhosis - management of gastrointestinal bleeding in the presence of portal hypertension].

PubMed

Hejda, Václav

Cirrhosis is the end stage of progressive development of different liver diseases and is associated with significant morbidity and mortality rates. Cirrhosis is associated with a number of potential complications, in particular with development of portal hypertension. Portal hypertension with the production of ascites, hepatic and gastric varices bleeding in the upper part of the gastrointestinal tract, presents the breakpoint in the natural course of cirrhosis, and it is associated with a considerably worse prognosis of patients, with a dramatically increased risk of mortality. A major progress was reached during the past 10-20 years in diagnosing liver cirrhosis (including non-invasive methods), in primary prevention of the initial episode of upper gastrointestinal bleeding and in the therapy of acute bleeding due to modern pharmacotherapy, with regard to expanding possibilities of therapeutic endoscopy and relatively new options for management of acute bleeding (esophageal stents, TIPS and suchlike). However acute upper gastrointestinal bleeding associated with portal hypertension still presents a considerable risk of premature death (15-20 %). Early diagnosing and causal treatment of numerous liver diseases may lead to slowing or regression of fibrosis and cirrhosis and possibly even of the degree of portal hypertension and thereby also the risk of bleeding.Key words: cirrhosis - esophageal varices - treatment of bleeding - portal hypertension.

Sentinel lymph node biopsy in gastrointestinal malignancies-where do we stand?

Sentinel lymph nodes (SLNs) are the nodes in direct communication with the primary tumor and are therefore the first group of nodes to be involved in lymphatic metastasis. Though the role of SLN biopsy is well established in cancers of the breast and melanoma, its role in gastrointestinal malignancies is still evolving and controversial. In this paper, the literature is reviewed with respect to the status of SLN biopsy in gastrointestinal malignancies.

Gastrointestinal metastasis to the breast.

Although primary breast cancer is common, metastatic disease to the breast, especially primary gastrointestinal cancer, is rare. Routine pathologic examination may be helpful in determining the true diagnosis, but can be misleading. To determine whether a signet ring carcinoma was a primary malignancy of the gastrointestinal tract metastatic to the breast or vice versa, histochemical analysis was performed for Her-2/NEU, gross cystic disease fluid protein-15, estrogen receptor, progesterone, carcinoembryonic antigen, cytokeratin 7, and cytokeratin 20. Positive staining for carcinoembryonic antigen and cytokeratin 20 (and negative staining for the breast cancer antigens), and the clinical criteria favors the diagnosis of gastrointestinal carcinoma metastatic to the mammary gland. Because the prognosis of therapy for metastatic cancer to the breast differs from that of primary breast cancer, it is imperative that the correct diagnosis be established. Immunohistochemistry for carcinoembryonic antigen and cytokeratin 20 are particularly useful. Metastatic gastrointestinal carcinoma to the breast is a rare lesion but needs to be at least included in the differential diagnosis of breast masses, especially in patients with a history of gastrointestinal cancer.

Defining disease with laser precision: laser capture microdissection in gastroenterology.

Laser capture microdissection (LCM) is an efficient and precise method for obtaining pure cell populations or specific cells of interest from a given tissue sample. LCM has been applied to animal and human gastroenterology research in analyzing the protein, DNA, and RNA from all organs of the gastrointestinal system. There are numerous potential applications for this technology in gastroenterology research, including malignancies of the esophagus, stomach, colon, biliary tract, and liver. This technology can also be used to study gastrointestinal infections, inflammatory bowel disease, pancreatitis, motility, malabsorption, and radiation enteropathy. LCM has multiple advantages when compared with conventional methods of microdissection, and this technology can be exploited to identify precursors to disease, diagnostic biomarkers, and therapeutic interventions.

Correspondence is an important source of documentation for studying health and, therefore, the gastrointestinal symptoms of diseases. We studied the gastrointestinal disease described in the Monumenta Borgia collection, which contains documents from the 16th century, mainly letters about Francis Borgia, the last great figure of a family originally from Valencia and with universal significance. Of the 2769 documents examined, 1231 (44.5%) contained some health-related descriptions and 42 items were related to gastrointestinal disease, representing 7.5% of the specific diseases of natural causes. The most frequently mentioned organ in the whole human body was the stomach, with 20 references. The most frequent references were to symptoms related to the upper gastrointestinal tract, with 18 references, and the lower gastrointestinal tract, with 16. The comments made on health related to gastrointestinal disease usually reflect the typical galenism of the medicine of the times. The disorders attributed to the stomach are described in varied terminology and include an acute episode of gastrointestinal bleeding. The most frequently mentioned symptoms and processes are diarrhea, flatulence, hernias, and, among those attributed to the lower gastrointestinal tract, lower gastrointestinal hemorrhages. Also mentioned are hemorrhoids and intestinal colic. Although little mention is made of the liver and spleen, there are various allusions that Francis Borgia was affected by disease or pathogenic alterations in this area. However, the postmortem examination of his corpse, refuted the existence of these anomalies. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

Update on HER2 testing for breast and upper gastrointestinal tract cancers.

PubMed

Ross, Jeffrey S

2011-06-01

With the regulatory approvals in Europe and the USA of trastuzumab-based anti-HER2 targeted therapy for upper gastrointestinal cancers in 2010, HER2 testing has now become universal for newly diagnosed cases of both breast cancer and adenocarcinomas of esophagus, stomach and gastroesophageal origin. In the 12 years or more since the approval of trastuzumab for breast cancer, general refinements in approaches to HER2 testing, including a greater understanding of the implications of preanalytic factors impacting the test results and the application of standardization of reporting of HER2 test results, have taken place. There has also been continuing development in breast cancer with the introduction of new HER2 tests, including non-FISH tests, dimerization assays, phosphorylated HER2 receptor tests, mRNA-based tests, HER2 gene sequencing tests and the application of HER2 testing to circulating tumor cells. Most recently, the introduction of HER2 testing for upper gastrointentinal malignancies has emphasized the need for performing and interpreting slide-based assays in a manner unique to these specimens and not to apply the breast cancer testing protocols to esophageal and gastric adenocarcinomas.

We report a rare case of a collision between a gastric cancer and a malignant lymphoma with a wide systemic metastasis, combined with esophagus cancer, stomach cancer and malignant lymphoma. A 73-year-old man complained of gross hematuria and swelling of the right testis. Magnetic resonance imaging (MRI) revealed that both testes were swollen with unequal contrast and there were numerous tumors in the retroperitoneal space and pelvis. He was diagnosed with malignant diffuse large B cell lymphoma by immunostaining from the extirpated right testis. He received six cycles of R-CHOP therapy. After the second cycle, partial remission was recognized, but the tumors spread again by the fourth cycle. Thereafter, we performed MTX-HOPE therapy as a salvage therapy for four cycles. During this chemotherapy, he felt epigastralgia; esophagus cancer (squamous cell carcinoma) and stomach cancer (highly-differentiated adenocarcinoma) were found by upper endoscopy. However, the gastrointestinal cancer was inoperable, since the malignant lymphoma was progressive. His general status had been exacerbated, and he died about one year after he was diagnosed with malignant lymphoma. Pathological examination revealed that the adenocarcinoma had partly collided with the malignant lymphoma.

A survey of the incidence of monocyte esterase deficiency in 4000 inpatients (including 808 with malignant neoplastic disease) and 474 normal controls was performed using an automated esterase method. A highly significant excess of patients with malignant disease and the deficiency was evident when compared with normal controls or all other patients. Within the group of patients with malignant disease the demonstrable excess occurred in B chronic lymphocytic leukaemia, non-Hodgkin's and Hodgkin's lymphoma, and carcinoma of the gastrointestinal tract. There was also a significant excess of patients with the deficiency attending the renal unit, both among patients who had had renal transplants and those who had not. A familial incidence of monocyte esterase deficiency was found in 19 (35%) of first degree relatives of those patients in whom family studies were done. It is suggested that the reason for the increased prevalence of the anomaly in these disorders might be that the diminution of esterase activity has a role in their development. PMID:2341564

Laparoscopic upper urinary tract surgery for benign and malignant conditions. Does aetiology have an effect on health-related quality of life?

We present health-related quality of life (HRQoL) data on a cohort of patients undergoing upper urinary tract laparoscopy for a variety of benign and malignant conditions. The Short Form 8 (SF-8) Health Survey is a validated HRQoL questionnaire that calculates scores for physical (PCS8) and mental (MCS8) components of health. It was administered prospectively to 58 patients. Radical nephrectomy or nephroureterectomy was carried out for upper tract malignancy (n = 21). Laparoscopy for benign disease (n = 37) included simple nephrectomy for giant hydronephrosis and small non-functioning kidneys, de-roofing of renal cysts and pyeloplasty. Data were collected before and 6 weeks after surgery. The mean pre- and postsurgery scores were 45.99; 47.43 and 43.93; 51.54 for PCS8 and MCS8 respectively. With regard to the PCS8 score, there was no significant difference before or after surgery (p = 0.585) or when analysing the benign (p = 0.343) or malignant (p = 0.509) groups individually. The MCS8 score, however, showed a significant increase after surgery (p < 0.0001). This remained significant when analysing just the benign (p < 0.0009) or the malignant (p < 0.0003) groups but neither group was more significant than the other (p = 0.750). Laparoscopic upper urinary tract surgery significantly improves mental and does not appear to reduce physical HRQoL in patients regardless of aetiology, 4 weeks following surgery. Interestingly, those operated on for malignant conditions do not have a greater improvement in mental health when compared with benign disease.

[Gastrointestinal bleeding].

Lanas, Ángel

2015-09-01

In the Digestive Disease Week in 2015 there have been some new contributions in the field of gastrointestinal bleeding that deserve to be highlighted. Treatment of celecoxib with a proton pump inhibitor is safer than treatment with nonselective NSAID and a proton pump inhibitor in high risk gastrointestinal and cardiovascular patients who mostly also take acetylsalicylic acid. Several studies confirm the need to restart the antiplatelet or anticoagulant therapy at an early stage after a gastrointestinal hemorrhage. The need for urgent endoscopy before 6-12 h after the onset of upper gastrointestinal bleeding episode may be beneficial in patients with hemodynamic instability and high risk for comorbidity. It is confirmed that in Western but not in Japanese populations, gastrointestinal bleeding episodes admitted to hospital during weekend days are associated with a worse prognosis associated with delays in the clinical management of the events. The strategy of a restrictive policy on blood transfusions during an upper GI bleeding event has been challenged. Several studies have shown the benefit of identifying the bleeding vessel in non varicose underlying gastric lesions by Doppler ultrasound which allows direct endoscopic therapy in the patient with upper GI bleeding. Finally, it has been reported that lower gastrointestinal bleeding diverticula band ligation or hemoclipping are both safe and have the same long-term outcomes.

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidence of bariatric operations and coherently possible complications after such procedures, which modify patient's anatomy and physiology.

To investigate the structure of dyspeptic symptoms and determine the association between dyspeptic symptoms and endoscopic findings in patients referred for upper gastrointestinal endoscopy by family physicians in a country with a high prevalence of Helicobacter pylori infection. Consecutive outpatients (n=172; median 36 years, range 18-75; 85 male; 87 female) were referred to upper gastrointestinal endoscopy. Patient history was recorded prior to upper gastrointestinal endoscopy using the computer-aided Glasgow Diagnostic System for Dyspepsia (GLADYS). Family physicians used open access endoscopy with a short waiting list. Two biopsies, both from the antrum and the corpus, were taken for histological assessment. Out of the 172 patients studied, 81% (n=139) were H. pylori positive, 65% (n=112) were younger than 45 years. The incidence of peptic ulcer was 44% (n=75). Upper abdominal pain was the predominant complaint in 73% (n=126) of the patients, as well as the most frequent overall complaint. Hunger pain, night pain, periodical nature of symptoms, and history over 2 years were of independent value in differentiating between peptic ulcer and functional dyspepsia. The symptoms of gastroesophageal reflux disease and irritable bowel syndrome predominated in the minority of patients (11% and 5% respectively) but accompanied other complaints in almost 2/3 of the patients. In 32 out of 75 patients with peptic ulcer, the symptoms of irritable bowel syndrome and in 29 cases the presence of frequent heartburn and regurgitation were noted. Classical symptoms are valuable in predicting the diagnosis of peptic ulcer. Heartburn and acid regurgitation are present in both gastroesophageal reflux disease and peptic ulcer. Irritable bowel syndrome is common in patients with peptic ulcer.

Purpose Since the effect of physician supply on utilization remains controversial, literature based on non-Medicare populations is sparse, and a physician supply expansion is underway, the potential for physician-induced demand across diverse populations is important to understand. A substantial proportion of gastrointestinal endoscopies may be inappropriate. The authors analyzed the impact of physician supply, practice patterns, and clinical history on esophagogastroduodenoscopy (EGD, defined as discretionary) among patients hospitalized with lower gastrointestinal bleeding (LGIB). Method Among 34,344 patients hospitalized for LGIB from 2004–2009, 43.1% and 21.3% had a colonoscopy or EGD, respectively, during the index hospitalization or within 6 months after. Linking to the Dartmouth Atlas via patients’ hospital referral region, gastroenterologist density and hospital care intensity (HCI) index were ascertained. Adjusting for age, gender, comorbidities, and race/education indicators, the association of gastroenterologist density, HCI index, and history of upper GI disease with EGD was estimated using logistic regression. Results EGD was not associated with gastroenterologist density or HCI index, but was associated with a history of any upper gastrointestinal disease (OR 2.30, 95% CI) 2.17–2.43), peptic ulcer disease (OR 4.82, 95% CI 4.26–5.45), and liver disease (OR 1.34, 95% CI 1.18–1.54). Conclusions Among patients hospitalized with LGIB, large variation in gastroenterologist density did not predict EGD, but relevant clinical history did, with association strengths commensurate with risk for upper gastrointestinal bleeding. In the scenario studied, the authors found no evidence that specialty physician supply increases will result in more discretionary care within commercially insured populations. PMID:28441679

The association between selective serotonin receptor inhibitors (SSRIs) and risk of upper gastrointestinal bleeding remains controversial. Previous studies have generally evaluated the issue for approximately 3 months, even though the SSRI-mediated inhibition of platelet serotonin concentrations occurs within 7-14 days. The authors explored the risk of upper gastrointestinal bleeding after short-term SSRI exposure by a case-crossover design. The records of psychiatric inpatients with upper gastrointestinal bleeding were retrieved from the Taiwan National Health Insurance Database (1998-2009). Rates of antidepressant use were compared for case and control periods with time windows of 7, 14, and 28 days. The adjusted self-matched odds ratios from a conditional logistic regression model were used to determine the association between SSRI use and upper gastrointestinal bleeding. A total of 5,377 patients with upper gastrointestinal bleeding were enrolled. The adjusted odds ratio for the risk of upper gastrointestinal bleeding after SSRI exposure was 1.67 (95% CI=1.23-2.26) for the 7-day window, 1.84 (95% CI=1.42-2.40) for the 14-day window, and 1.67 (95% CI=1.34-2.08) for the 28-day window. SSRIs with high and intermediate, but not low, affinity for serotonin transporter were associated with upper gastrointestinal bleeding. An elevated risk of upper gastrointestinal bleeding after SSRI exposure was seen in male but not female patients. Short-term SSRI use (7-28 days) is significantly associated with upper gastrointestinal bleeding. Gender differences may exist in the relationship between SSRI use and upper gastrointestinal bleeding. Physicians should carefully monitor signs of upper gastrointestinal bleeding even after short-term exposure to SSRIs, as is done with nonsteroidal anti-inflammatory drugs and aspirin.

"Exercise-induced gastrointestinal syndrome" refers to disturbances of gastrointestinal integrity and function that are common features of strenuous exercise. To systematically review the literature to establish the impact of acute exercise on markers of gastrointestinal integrity and function in healthy populations and those with chronic gastrointestinal conditions. Search literature using five databases (PubMed, EBSCO, Web of Science, SPORTSdiscus, and Ovid Medline) to review publications that focused on the impact of acute exercise on markers of gastrointestinal injury, permeability, endotoxaemia, motility and malabsorption in healthy populations and populations with gastrointestinal diseases/disorders. As exercise intensity and duration increases, there is considerable evidence for increases in indices of intestinal injury, permeability and endotoxaemia, together with impairment of gastric emptying, slowing of small intestinal transit and malabsorption. The addition of heat stress and running mode appears to exacerbate these markers of gastrointestinal disturbance. Exercise stress of ≥2 hours at 60% VO 2max appears to be the threshold whereby significant gastrointestinal perturbations manifest, irrespective of fitness status. Gastrointestinal symptoms, referable to upper- and lower-gastrointestinal tract, are common and a limiting factor in prolonged strenuous exercise. While there is evidence for health benefits of moderate exercise in patients with inflammatory bowel disease or functional gastrointestinal disorders, the safety of more strenuous exercise has not been established. Strenuous exercise has a major reversible impact on gastrointestinal integrity and function of healthy populations. The safety and health implications of prolonged strenuous exercise in patients with chronic gastrointestinal diseases/disorders, while hypothetically worrying, has not been elucidated and requires further investigation. © 2017 John Wiley & Sons Ltd.

Acute upper gastrointestinal (GI) bleeding is a common medical emergency. A common risk factor of upper GI bleeding is cirrhosis of liver, which can lead to variceal haemorrhage. 30-40% of cirrhotic patients who bleed may have non-variceal upper GI bleeding and it is frequently caused by peptic ulcers, portal gastropathy, Mallory-Weiss tear, and gastroduodenal erosions. The objective of this study was to determine the frequency of upper gastrointestinal endoscopic findings among patients presenting with upper gastrointestinal bleeding with liver cirrhosis. This descriptive cross-sectional study was carried out in Gastroenterology & Hepatology Department of Ayub Teaching Hospital, Abbottabad from February 2012 to June 2013. 252 patients diagnosed with cirrhosis, presenting with upper GI bleed, age 50 years of either gender, and were included in the study. Non-probability consecutive sampling was used, Endoscopy was performed on each patient and the findings documented. The mean age was 57.84 +/- 6.29 years. There were 158 (62.7%) males and 94 (37.3%) females. The most common endoscopic finding was oesophageal varices (92.9%, n=234) followed by portal hypertensive gastropathy (38.9%, n=98) with almost equal distribution among males and females. Gastric varices were found in 33.3% of patients (n=84). Among other non-variceal lesions, peptic ulcer disease was seen in 26 patients (10.3%) while gastric erosions were found in 8 patients (3.2%). In patients with acute upper GI bleeding and liver cirrhosis, the most common endoscopic finding is oesophageal varices, with a substantially higher value in our part of the country, apart from other non-variceal causes.

Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR. A history of upper gastrointestinal bleeding (P<0.001) and lower serum albumin (P=0.004) were independently associated with higher upper gastrointestinal bleeding risk. In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding. The risk is higher in patients with previous upper gastrointestinal bleeding history and low serum albumin. Copyright © 2014 by the American Society of Nephrology.

Defining disease with laser precision: laser capture microdissection in gastroenterology

PubMed Central

Blatt, Richard; Srinivasan, Shanthi

2013-01-01

Laser capture microdissection (LCM) is an efficient and precise method for obtaining pure cell populations or specific cells of interest from a given tissue sample. LCM has been applied to animal and human gastroenterology research in analyzing the protein, DNA and RNA from all organs of the gastrointestinal system. There are numerous potential applications for this technology in gastroenterology research including malignancies of the esophagus, stomach, colon, biliary tract and liver. This technology can also be used to study gastrointestinal infections, inflammatory bowel disease, pancreatitis, motility, malabsorption and radiation enteropathy. LCM has multiple advantages when compared to conventional methods of microdissection, and this technology can be exploited to identify precursors to disease, diagnostic biomarkers, and therapeutic interventions.

Small cell undifferentiated carcinoma (SmCC) of the gastrointestinal tract (GIT) is a rare and highly aggressive malignancy. To date, fewer than 1,000 cases have been reported, with an estimated prevalence of 0.1% to 1% of all gastrointestinal (GI) tumors. Data on the disease are scarce due to its rarity and the fact that most authors have focused on one site within the GIT. In light of the limited data and its perceived similarity to SmCC of the lung, the disease has usually been treated as the latter. Nevertheless, recent clinicopathologic and molecular data imply several differences between the two entities, questioning the extent to which extrapolations from one to the other can be made. We review the available data on GI SmCC with emphasis on outlining its clinicopathologic features and the recommended treatment approach.

To determine the risk factors, causes, and outcome of clinically important upper gastrointestinal bleeding that occurs in severely burned patients. The charts of all patients admitted to the burn intensive care unit were analyzed retrospectively over a 4-year period (from January 2006 to December 2009). Cases consisted of burned patients who developed upper gastrointestinal bleeding more than 24 hours after admission to the burn intensive care unit. Controls were a set of patients, in the burn intensive care unit, without upper gastrointestinal bleeding matched with cases for age and gender. Cases and controls were compared with respect to the risk factors of upper gastrointestinal bleeding and outcomes. During the study period, clinically important upper gastrointestinal bleeding occurred in 20 patients out of all 964 patients. The most common cause of upper gastrointestinal bleeding was duodenal ulcer (11 of 20 cases, 55%). In the multivariate analysis, mechanical ventilation (p = 0.044) and coagulopathy (p = 0.035) were found to be the independent predictors of upper gastrointestinal bleeding in severely burned patients. Upper gastrointestinal hemorrhage tends to occur more frequently after having prolonged mechanical ventilation and coagulopathy.

Intraperitoneal chemotherapy together with cytoreductive surgery is the standard of care for a number of peritoneal surface malignancies. However, this approach fails to maintain the complete response and disease recurs due to microscopic residual disease. Although safer than systemic chemotherapy regimens, locoregional treatment with chemotherapeutics can induce toxicity which is a major concern affecting the patient’s treatment protocol and outcome. For an enhanced treatment efficacy, efforts should be made to maximize cytotoxic effects of chemotherapeutic agents on tumor cells while minimizing their toxic effects on host cells. Bromelain and N-acetylcysteine are two natural agents with good safety profiles shown to have anti-cancer effects. However, their interaction with chemotherapeutics is unknown. In this study, we investigated if these agents have the potential to sensitize in vitro gastrointestinal cancer models to cisplatin, paclitaxel, 5-fluorouracil, and vincristine. The drug-drug interaction was also analyzed. Our findings suggest that combination of bromelain and N-acetylcysteine with chemotherapeutic agents could give rise to an improved chemotherapeutic index in therapeutic approaches to peritoneal surface malignancies of gastrointestinal origin so that maximum benefits could result from less toxic and more patient-friendly doses. This represents a potentially efficacious strategy for the enhancement of microscopic cytoreduction and is a promising area for future research. PMID:27186409

Stress and the gut: pathophysiology, clinical consequences, diagnostic approach and treatment options.

Stress, which is defined as an acute threat to homeostasis, shows both short- and long-term effects on the functions of the gastrointestinal tract. Exposure to stress results in alterations of the brain-gut interactions ("brain-gut axis") ultimately leading to the development of a broad array of gastrointestinal disorders including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and other functional gastrointestinal diseases, food antigen-related adverse responses, peptic ulcer and gastroesophageal reflux disease (GERD). The major effects of stress on gut physiology include: 1) alterations in gastrointestinal motility; 2) increase in visceral perception; 3) changes in gastrointestinal secretion; 4) increase in intestinal permeability; 5) negative effects on regenerative capacity of gastrointestinal mucosa and mucosal blood flow; and 6) negative effects on intestinal microbiota. Mast cells (MC) are important effectors of brain-gut axis that translate the stress signals into the release of a wide range of neurotransmitters and proinflammatory cytokines, which may profoundly affect the gastrointestinal physiology. IBS represents the most important gastrointestinal disorder in humans, and is characterized by chronic or recurrent pain associated with altered bowel motility. The diagnostic testing for IBS patients include routine blood tests, stool tests, celiac disease serology, abdominal sonography, breath testing to rule out carbohydrate (lactose, fructose, etc.) intolerance and small intestinal bacterial overgrowth. Colonoscopy is recommended if alarming symptoms are present or to obtain colonic biopsies especially in patients with diarrhoea predominant IBS. The management of IBS is based on a multifactorial approach and includes pharmacotherapy targeted against the predominant symptom, behavioural and psychological treatment, dietary alterations, education, reassurance and effective patient-physician relationship. When evaluating for the stress-induced condition in the upper GI tract, the diagnostic testing includes mainly blood tests and gastroscopy to rule out GERD and peptic ulcer disease. The therapy for these conditions is mainly based on the inhibition of gastric acid by proton pump inhibitors and eradication of Helicobacter pylori-infection. Additionally, melatonin an important mediator of brain gut axis has been shown to exhibit important protective effects against stress-induced lesions in the gastrointestinal tract. Finally, probiotics may profoundly affect the brain-gut interactions ("microbiome-gut-brain axis") and attenuate the development of stress-induced disorders in both the upper and lower gastrointestinal tract. Further studies on the brain-gut axis are needed to open new therapeutic avenues in the future.

Totally implantable venous access devices (ports) are widely used, especially for cancer chemotherapy. Although their use has been associated with upper extremity deep venous thrombosis, the risk factors of upper extremity deep venous thrombosis in patients with a port are not studied adequately. The Healthcare Cost and Utilization Project's Florida State Ambulatory Surgery and Services Database was queried between 2007 and 2011 for patients who underwent outpatient port insertion, identified by Current Procedural Terminology code. Patients were followed in the State Ambulatory Surgery and Services Database, State Inpatient Database, and State Emergency Department Database for upper extremity deep venous thrombosis occurrence. The cohort was divided into a test cohort and a validation cohort based on the year of port placement. A multivariable logistic regression model was developed to identify risk factors for upper extremity deep venous thrombosis in patients with a port. The model then was tested on the validation cohort. Of the 51,049 patients in the derivation cohort, 926 (1.81%) developed an upper extremity deep venous thrombosis. On multivariate analysis, independently significant predictors of upper extremity deep venous thrombosis included age <65 years (odds ratio = 1.22), Elixhauser score of 1 to 2 compared with zero (odds ratio = 1.17), end-stage renal disease (versus no kidney disease; odds ratio = 2.63), history of any deep venous thrombosis (odds ratio = 1.77), all-cause 30-day revisit (odds ratio = 2.36), African American race (versus white; odds ratio = 1.86), and other nonwhite races (odds ratio = 1.35). Additionally, compared with genitourinary malignancies, patients with gastrointestinal (odds ratio = 1.55), metastatic (odds ratio = 1.76), and lung cancers (odds ratio = 1.68) had greater risks of developing an upper extremity deep venous thrombosis. This study identified major risk factors of upper extremity deep venous thrombosis. Further studies are needed to evaluate the appropriateness of thromboprophylaxis in patients at greater risk of upper extremity deep venous thrombosis. Copyright © 2017 Elsevier Inc.

The impact of proton pump inhibitors on the human gastrointestinal microbiome

PubMed Central

Freedberg, Daniel E.; Lebwohl, Benjamin; Abrams, Julian A.

2014-01-01

Potent gastric acid suppression using proton pump inhibitors (PPIs) is common in clinical practice yet may have important effects on human health that are mediated through changes in the gastrointestinal microbiome. Acting through pH-dependent or pH-independent mechanisms, PPIs have the potential to alter the normal microbiota throughout the human gastrointestinal lumen. In the esophagus, PPIs change the normal bacterial milieu to decrease distal esophageal exposure to inflammatory Gram-negative bacteria which may lower the risk of Barrett's esophagus. In the stomach, PPIs alter the abundance and location of gastric Helicobacter pylori and other bacteria, which has implications for peptic ulcer disease and gastric malignancy. In the small bowel, PPIs cause polymicrobial small bowel bacterial overgrowth and have been associated with the diagnosis of celiac disease. In the colon, PPIs associate with incident but not recurrent Clostridium difficile infection, putatively through alterations in commensal colonic anaerobes. Our understanding of the effect of gastric acid suppression on the human gastrointestinal microbiome is incomplete but is rapidly advancing. PMID:25439276

Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major post-operative complications in an international cohort and to present a meta-analysis of all available prospective data. This prospective, multi-centre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma, or formation of stoma. The primary endpoint was 30-day major complications (Clavien-Dindo grades III-V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis (IPMA) was used to analyse pooled results. This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese versus normal weight patients (13.0% versus 16.2%, respectively), but this did not reach statistical significance (p=0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. IPMA demonstrated that obese patients undergoing surgery for malignancy were at increased risk of major complications (odds ratio 2.10, 95% confidence interval 1.49-2.96, p<0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46-0.75, p<0.001), compared to normal weight patients. In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease.

To investigate whether omeprazole has improved morbidity-mortality among patients with upper gastrointestinal bleeding of non-variceal origin in comparison with ranitidine. Prospective, randomized and open study. We study 519 consecutive patients admitted to our Service between June 1991 and January 1993 for upper gastrointestinal bleeding of peptic origin, dividing the patients into two randomized groups that were homogeneous in terms of age, sex, previous history of gastric disease and upper gastrointestinal bleeding, intake of non-steroidal antiinflammatory drugs, and the severity of bleeding on admittance. Thus, Group A consisted of 252 patients treated immediately upon arrival at the emergency ward with 50 mg intravenous ranitidine, followed by a further 50 mg every 6 hours. Group B in turn consisted of 267 patients initially given a bolus dose of 80 mg omeprazole intravenously, followed by an additional 40 mg every 8 hours for 48 hours. Forty mg were subsequently administered every 12 hours until hospital discharge. Endoscopy was performed in all cases within the first 24 hours following admittance, those patients with active upper gastrointestinal bleeding resulted from Forrest-type ulcer of subjected to endoscopic sclerotherapy were excluded. Duodenal ulcer was the most common cause of bleeding, followed by gastric ulcer and acute lesions of the mucosa. Emphasis should be placed on the high incidence of previous non-steroidal antiinflammatory drug intake in our series (54.5%). We encountered no statistically significant differences between the two groups on comparing bleeding stigmata, transfusion requirements, recurrences, emergency surgery, the duration of hospital stay, and mortality. Both drugs were found to possess a similar efficacy in treating upper gastrointestinal bleeding of peptic origin.

Upper gastrointestinal (GI) diseases are common, but there is a paucity of data describing variations by ethnic group and so a lack of understanding of potential health inequalities. We studied the incidence of specific upper GI hospitalization and death by ethnicity in Scotland. Using the Scottish Health and Ethnicity Linkage Study, linking NHS hospitalizations and mortality to the Scottish Census 2001, we explored ethnic differences in incidence (2001-10) of oesophagitis, peptic ulcer disease, gallstone disease and pancreatitis. Relative Risks (RRs) and 95% confidence intervals were calculated using Poisson regression, multiplied by 100, stratified by sex and adjusted for age, country of birth (COB) and socio-economic position. The White Scottish population (100) was the reference population. Ethnic variations varied by outcome and sex, e.g. adjusted RRs (95% confidence intervals) for oesophagitis were comparatively higher in Bangladeshi women (209; 124-352) and lower in Chinese men (65; 51-84) and women (69; 55-88). For peptic ulcer disease, RRs were higher in Chinese men (171; 131-223). Pakistani women had higher RRs for gallstone disease (129; 112-148) and pancreatitis (147; 109-199). The risks of upper GI diseases were lower in Other White British and Other White [e.g. for peptic ulcer disease in men, respectively (74; 64-85) and (81; 69-94)]. Risks of common upper GI diseases were comparatively lower in most White ethnic groups in Scotland. In non-White groups, however, risk varied by disease and ethnic group. These results require consideration in health policy, service planning and future research. © The Author 2015.

Primary gastrointestinal lymphoma

Gastrointestinal tract is the most common extranodal site involved by lymphoma with the majority being non-Hodgkin type. Although lymphoma can involve any part of the gastrointestinal tract, the most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and primary gastrointestinal tract lymphoma is relatively rare. Gastrointestinal lymphomas are usually not clinically specific and indistinguishable from other benign and malignant conditions. Diffuse large B-cell lymphoma is the most common pathological type of gastrointestinal lymphoma in essentially all sites of the gastrointestinal tract, although recently the frequency of other forms has also increased in certain regions of the world. Although some radiological features such as bulky lymph nodes and maintenance of fat plane are more suggestive of lymphoma, they are not specific, thus mandating histopathological analysis for its definitive diagnosis. There has been a tremendous leap in the diagnosis, staging and management of gastrointestinal lymphoma in the last two decades attributed to a better insight into its etiology and molecular aspect as well as the knowledge about its critical signaling pathways.

2013-06-01

Upper gastrointestinal endoscopies are primarily performed to observe the pathologies of the esophagus, stomach, and duodenum. However, when an endoscope is pushed into the esophagus or stomach by the physician, the organs behave similar to a balloon being gradually inflated. Consequently, their shapes and depth-of-field of images change continually, preventing thorough examination of the inflammation or anabrosis position, which delays the curing period. In this study, a 2.9-mm image-capturing module and a convoluted mechanism was incorporated into the tube like a standard 10- mm upper gastrointestinal endoscope. The scale-invariant feature transform (SIFT) algorithm was adopted to implement disease feature extraction on a koala doll. Following feature extraction, the smoothly varying affine stitching (SVAS) method was employed to resolve stitching distortion problems. Subsequently, the real-time splice software developed in this study was embedded in an upper gastrointestinal endoscope to obtain a panoramic view of stomach inflammation in the captured images. The results showed that the 2.9-mm image-capturing module can provide approximately 50 verified images in one spin cycle, a viewing angle of 120° can be attained, and less than 10% distortion can be achieved in each image. Therefore, these methods can solve the problems encountered when using a standard 10-mm upper gastrointestinal endoscope with a single camera, such as image distortion, and partial inflammation displays. The results also showed that the SIFT algorithm provides the highest correct matching rate, and the SVAS method can be employed to resolve the parallax problems caused by stitching together images of different flat surfaces.

Gastric lipoma presenting as a giant bulging mass in an oligosymptomatic patient: a case report

PubMed Central

2012-01-01

Introduction Lipomas of the gastrointestinal tract are a rare condition. Only 5% are of gastric origin, and this corresponds to 2% to 3% of all benign tumors of the stomach and less than 1% of all gastric neoplasms. It is our purpose to report an unusual presentation of a giant gastric lipoma in an oligosymptomatic patient and highlight the importance of discussing differential diagnosis in this situation. A review of the literature has shown that this is one of the largest gastric lipomas described. Case presentation We describe a rare case of a benign gastric tumor with uncommon features in a 63-year-old Caucasian woman. She was admitted with abdominal discomfort, nausea, and upper abdominal fullness after eating. The lesion was suspicious of malignancy because of its dimension and central contrast enhancement on computed tomography. Conventional upper digestive endoscopy revealed a large bulging mass in the gastric posterior wall and three ulcerated areas. In this procedure, a technical limitation due to the location of the mass in the submucosa prevented an adequate biopsy from being obtained. The fragments obtained from the ulcers revealed nothing but necrotic mucosa. Our patient underwent a subtotal gastrectomy and D1 lymphadenectomy with a Roux-en-Y reconstruction. Macroscopic findings revealed a 12 × 8 × 6cm mass with a volume of 576cm3, and the histological pattern demonstrated well-differentiated mature adipose tissue surrounded by a fibrous capsule, confirming the diagnosis of gastric submucosal lipoma. Conclusions Gastric lipoma is a rare benign disease that eventually simulates a malignant tumor. PMID:23006791

Atraumatic infections due to Clostridium septicum are known to be associated with immunosuppression or even malignancy. In this case report, we present a patient with severe Clostridium septicum infection related to advanced colon cancer that had not previously been diagnosed. The case demonstrates the strong association between Clostridium septicum infections and malignancy, particularly in the presence of other predisposing diseases such as diabetes mellitus. It strongly suggests excluding malignant neoplasms, especially of the gastrointestinal tract, when severe Clostridium septicum infections occur. Moreover, if patients with known colorectal or other malignancy develop septicaemia or spontaneous gas gangrene, clinicians should be aware of Clostridium septicum as one of the main causative agents, as early diagnosis and aggressive treatment are important to improve prognosis.

Gastrointestinal stromal tumors are the most frequent non-epithelial digestive tumors, being classified in the group of primitive mesenchymal tumors of the digestive tract. These tumors have a non predictable evolution and where stratified regarding the risk for malignant behavior in 4 categories: very low risk, low risk, intermediate risk and high risk. We performed a retrospective non randomised study including the patients with gastrointestinal stromal tumors treated in the Department of General Surgery and Liver Transplantation of Fundeni Clinical Institute in the period January 2002 - June 2007, to define the epidemiological, clinico-paraclinical, histological and especially evolutive features of the gastrointestinal stromal tumors from this group, with a special regard to the risk factors for their malignant behavior. The most important risk factors in gastrointestinal stromal tumors are the tumor size and the mitotic index, based on them being realised the classification of Fletcher in the 4 risk categories mentioned above. In our group all the local advanced or metastatic gastrointestinal stromal tumors, regardless of their location, were classified in the group of high risk for the malignant behavior. The gastric location and the epithelioid type were positive prognostic factors, and the complete resection of the tumor, an other important positive prognostic feature, was possible in about 80% of the cases, probably because the gastrointestinal stromal tumors in our study were diagnosed in less advanced evolutive situations, only about one third being metastatic and about 14% being locally advanced at the time of diagnose. The association with other neoplasias was in our cases insignificant, only 5% of the patients presenting concomitant malignant digestive tumors and 7.6% intraabdominal benign tumors. Gastrointestinal stromal tumors remain a challenge for the medical staff, regarding their diagnose and therapeutical management, the stratification of the risk for their malignant behavior being essential for the evolution of these patients.

Helicobacter pylori is a known contributor to ulcerogenesis and nonvariceal acute upper gastrointestinal hemorrhage. Its incidence in operatively managed patients with upper gastrointestinal hemorrhage is ill defined. Patients undergoing surgery for upper gastrointestinal hemorrhage secondary to gastroduodenal ulceration between 1993 and 1998 at the University of Tennessee were retrospectively reviewed. Factors examined included age, nonsteroidal drug use, endoscopic intervention, urgency of operation, and H. pylori status confirmed by histologic examination. Forty-two patients had surgery with three excluded because of a lack of histologic evaluation. The site of bleeding was gastric in 23 and duodenal in 14. H. pylori infection was present in nine (39.1%) gastric and 11 (68.7%) duodenal ulcers. The incidence of H. pylori infection was reduced in those over 60 years of age (28.6%). Endoscopy was performed in all patients, but only two had biopsies for assessment of H. pylori. Operative morbidity was 17.9% and mortality was 5.1%. No patient had rebleeding following surgery. The incidence of H. pylori in this population is less than that reported in uncomplicated ulcer disease. Those older than 60 tended to be H. pylori negative. Endoscopic assessment for H. pylori was infrequent. Traditional indications for surgical intervention in ulcer hemorrhage should not be altered based on H. pylori status.

Sixty-four patients with primary fallopian tube cancer treated at Roswell Park Memorial Institute from 1964 to 1987 underwent retrospective clinicopathologic review. In 40 patients fallopian tube cancer was the only primary, but in 24 patients primary fallopian tube cancer was part of a multifocal upper genital tract malignancy. Of the 40 patients with unifocal fallopian disease, the median survival was 28 months. Only 15% of patients were alive and disease free with follow-up ranging from 22 to 141 months (median, 90.5 months). Survival was not associated with stage of disease, tumor histology, grade, or depth of invasion in this series. Fourteen patients who received cisplatin-based chemotherapy were evaluable for response. Three patients (21%) responded; two complete and one partial. Twelve patients without clinical evidence of disease underwent second-look procedures, ten laparotomy and two laparoscopy. Four of ten second-look laparotomies were negative. Secondary debulking was done in three of four patients with gross disease, one of which had a negative third-look laparotomy. Negative laparotomy, second-look or third-look, was associated with improved survival (P = 0.016). One of the two laparoscopies was negative, but the patient recurred. In the remaining 24 patients cancer of the fallopian tube was part of a multifocal upper genital tract malignancy. In 12 patients tubal disease was invasive, and in 12, it was in situ. Separate primaries occurred in the ovaries (n = 20); uterus (n = 7); and cervix (n = 2). This represents 1.3% of ovarian malignancies treated at Roswell Park Memorial Institute during the study period. Fallopian tube cancer seems as virulent as ovarian cancer with few long-term survivors. It is frequently associated with other sites of upper genital tract malignancy. Second-look laparotomy is an important predictor of survival. Second-look laparoscopy may be useful if positive.

Diagnosis of focal disease, the theory that the human oral microbial (HOM) could affect the onset and development of systemic diseases, was very popular in the past, but the lack of scientific evidence has led to the abandonment of this idea. Interestingly, increasing evidence over the past 3 or so decades suggests that HOM can indeed serve as a reservoir for systemic dissemination of pathogenic bacteria and their toxins in distant body sites, favouring the developments of malignant tumours. Malignant tumours are complex communities of oncogenically transformed cells with aberrant genomes, associated non-neoplastic cells including immune and stromal cells, and sometimes HOM, including bacteria and viruses. Recent data suggest that HOM and periodontal disease play an active role in the pathogenesis of colorectal cancer, in fact HOM has been found within the colorectal cancer microenvironment, and the composition of the HOM was different from that of adjacent non-neoplastic tissue. An association of fusobacterium nucleatum with the colonic mucosa of colorectal cancer has been proven. Several questions thus arise. Is periodontal disease a risk factor for colorectal carcinoma? Given the connectivity of the digestive tract, could fusubacterium nucleatum or other HOM be involved in additional gastrointestinal disorders? Furthermore, based on the "mobility" of Fusubacterium nucleatum and the omnipresence of cadherins, could this organism be involved in cancers beyond the gastrointestinal tract? Answers to these questions will shed new lights on the role of the HOM in onset of diseases.

Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidence of bariatric operations and coherently possible complications after such procedures, which modify patient’s anatomy and physiology.

Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta. Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6%) patients who were proved to have cirrhosis were the subject of the present study. From all cirrhotic portal hypertensive patients, 415 (75.5%) bled from variceal sources (esophageal and gastric) while 135 (24.5%) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding. Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.

Gastrointestinal mucositis is one of the most prevalent side effects of chemotherapy. Methotrexate is a pro-oxidant compound that depletes dihydrofolate pools and is widely used in the treatment of leukemia and other malignancies. Through its effects on normal tissues with high rates of proliferation, methotrexate treatment leads to gastrointestinal mucositis. In rats, methotrexate-induced gastrointestinal mucositis is histologically characterized by crypt loss, callus fusion and atrophy, capillary dilatation, and infiltration of mixed inflammatory cells. The water-soluble dietary fiber sodium alginate (AL-Na) is derived from seaweed and has demonstrated muco-protective and hemostatic effects on upper gastrointestinal ulcers. In the present study, we evaluated the effects of AL-Na on methotrexate-induced small intestinal mucositis in rats. Animals were subcutaneously administered methotrexate at a dosage of 2.5 mg/kg once daily for 3 d. Rats were treated with single oral doses of AL-Na 30 min before and 6 h after methotrexate administration. On the 4th day, small intestines were removed and weighed. Subsequently, tissues were stained with hematoxylin-eosin and bromodeoxyuridine. AL-Na significantly prevented methotrexate-induced small intestinal mucositis. Moreover, AL-Na prevented decreases in red blood cell numbers, hemoglobin levels, and hematocrit levels. These results suggest the potential of AL-Na as a therapy for methotrexate-induced small intestinal mucositis.

Self-expandable metal stents (SEMSs) can be used for the palliation of malignant obstruction in the upper gastrointestinal tract. This study assessed the feasibility and efficacy of endoscopically inserted SEMSs for the palliation of malignant obstruction in the stomach and duodenum. Between January 2011 and April 2014, 220 patients with gastric or duodenal obstruction due to malignancy underwent endoscopic SEMS insertion at Asan Medical Center. The associations of technical/clinical outcomes and complications with the type of stent and site of obstruction were analyzed. The 220 patients included 125 men (56.8 %) and 95 women (43.2 %); median patient age was 63 years. Fully covered, partially covered, and uncovered SEMSs were inserted into 16, 77, and 120 patients, respectively. Obstructions were located in the gastric outlet, including the duodenal bulb, in 106 patients, and in the duodenal second and third portions in 114 patients. Technical success was achieved in 213 of 220 patients (96.8 %) and clinical success in 184 of 213 (86.4 %). Clinical success rates were similar to the type of stent, but were significantly greater for gastric outlet (95/104, 91.3 %) than for duodenal (89/109, 81.7 %) obstructions (p = 0.039). Stent migration was observed in 20 patients (9.1 %) and stent obstruction in 51 (23.2 %). Rates of stent migration were significantly higher for fully covered (6/16, 37.5 %) than for partially covered (7/77, 9.1 %) and uncovered (7/120, 5.8 %) SEMSs (p < 0.001) and were significantly higher for gastric outlet (16/104, 15.4 %) than for duodenal (4/109, 1.2 %) obstructions (p = 0.003). Rates of stent obstruction were similar for fully covered (2/16, 12.5 %), partially covered (17/77, 22.1 %), and uncovered (32/120, 26.7 %) SEMSs (p = 0.409) and in patients with gastric outlet (26/104, 25.0 %) and duodenal (25/109, 22.9 %) obstruction (p = 0.724). SEMS selection for malignant obstruction of the upper gastrointestinal tract depends on the site of obstruction.

Behçet's disease (BD) is a multisystemic disorder that involves vessels of all sizes. Superior vena cava (SVC) thrombosis is a rare complication that can lead to the development of various collateral pathways. A 31-year-old man presented with SVC syndrome. He had a history of recurrent genital aphthosis. Computed tomography revealed extensive thrombosis of the right internal jugular, axillary, and subclavian veins with collateral circulation. The patient was diagnosed with BD, and he was started on anticoagulation and immunosuppressive therapy. One week later, he presented with haematemesis. Upper gastrointestinal endoscopy disclosed varices in the upper third of the oesophagus with stigmata of recent bleeding. Portal hypertension was ruled out. Anticoagulation therapy was discontinued. He was discharged on immunosuppressive therapy. Bleeding from downhill oesophageal varices should be suspected in any patient presenting with upper gastrointestinal bleeding and a history of SVC syndrome due to BD.

Laboratory screening markers in gastroenterology--state of the art.

PubMed

Kocna, Petr; Vanickova, Zdislava; Zima, Tomas

2013-06-01

Screening tests for gastrointestinal diseases acceptable for population with a high sensitivity and high specificity can now be offered by clinical laboratories. This paper summarizes major recent advances in this area of laboratory medicine. Relevant articles published within the last 5 years in the NLM (National Library of Medicine) PubMed - Medline database covering the three gastrointestinal diseases - colorectal cancer, coeliac disease, and atrophic gastritis were included for this overview. In Europe, colorectal cancer (CRCA) is the second most frequent malignant disease. Quantitative immunochemical analysis of the stool for haemoglobin provides the best screening test to date, with both sensitivity and specificity approaching 95%. Even though coeliac disease (CD) affects approximately 1% of the general population, it remains largely unrecognised. Recommended methods for screening currently involve the detection of IgA and IgG antibodies against tissue transglutaminase and deamidated gliadin peptide. Evaluations of screening are now discussed for other diseases of the gastrointestinal tract - such as chronic atrophic gastritis (CAG), and inflammatory bowel disease (IBD). Detection of infection by Helicobacter pylori and stomach-specific plasmatic biomarkers, especially pepsinogen I/II ratio, could help with the prevention of gastric carcinomas. The use of faecal calprotectin as a screening test could substantially reduce the number of invasive methods necessary for the diagnostic work-up of patients with IBD. Screening tests for CRCA and CD have been used worldwide for many years. Screening strategies for gastrointestinal diseases are suggested in the text, based on recent basic science, clinical papers as well as our own experience.

Patients with cancer are at high risk for thrombotic events, which are known collectively as Trousseau's syndrome. Herein, we report a 66-year-old male patient who was diagnosed with terminal stage gastric cancer and liver metastasis and who had an initial clinical presentation of upper gastrointestinal bleeding. Acute ischemia of the left lower leg that resulted in gangrenous changes occurred during admission. Subsequent angiography of the left lower limb was then performed. This procedure revealed arterial thrombosis of the left common iliac artery with extension to the external iliac artery, the left common iliac artery, the posterior tibial artery, and the peroneal artery, which were occluded by thrombi. Aspiration of the thrombi demonstrated that these were not tumor thrombi. The interesting aspect of our case was that the disease it presented as arterial thrombotic events, which may correlate with gastric adenocarcinoma. In summary, we suggested that the unexplained thrombotic events might be one of the initial presentations of occult malignancy and that thromboprophylaxis should always be considered.

The development of gastric dysplasia and neoplasia in patients with pernicious anaemia has been evaluated in a prospective clinical and endoscopic follow up study. After initial screening of 80 patients between 1978 and 1980, one patient underwent total gastrectomy for a gastric malignancy and 12 were kept under surveillance and underwent endoscopy at a mean interval of 14 months. In the remaining 67 patients further investigation was attempted six to seven years after the initial investigation. The continuous follow up study identified carcinoids in one patient and an adenoma with severe dysplasia in a further patient. The grade and site of mucosal dysplasia differed from one investigation to the next, but no overall progression was observed. Of the 79 patients, eight had died by the time of the reinvestigation, two of unknown cause and six of causes unrelated to pernicious anaemia. In 38 of the remaining 71 patients, clinical data only were available, with no evidence of new gastric malignancy. In 27 patients it was possible to perform an upper gastrointestinal endoscopy, when no change in the degree of dysplasia was detected. In six patients no follow up information was obtainable. In conclusion, patients with pernicious anaemia should be investigated by upper gastrointestinal endoscopy soon after diagnosis. Polyps should be removed wherever possible. In the presence of severe mucosal dysplasia or polyps that are not removed, frequent reinvestigation should be performed, provided the patient is eligible for gastric surgery. In the remaining patients, follow up endoscopies at about five year intervals would seem sufficient. PMID:2083855

The objective of this study is to evaluate the gastric emptying in patients with systemic lupus erythematosus (SLE) with gastrointestinal involvement using three-dimensional (3D) ultrasonography. The gastric emptying times at 25% (T1), 50% (T2), and 75% (T3) of SLE patients with gastrointestinal involvement (n = 40) and healthy controls (n = 80) were evaluated and compared. In addition, the correlations among the gastric wall thickness, SLE disease activity index (SLEDAI), and upper gastrointestinal symptoms were calculated. The gastric wall thickness was correlated with the SLEDAI (r = 0.928, p < 0.001) and the upper gastrointestinal symptom index (r = 0.848, p < 0.001). The emptying times T1, T2, and T3 of the SLE patients were 17.08 ± 2.65 min (mean ± standard deviation), 39.85 ± 6.54 min, and 83.58 ± 7.12 min, respectively. For healthy controls, they were 19.65 ± 5.39 min, 41.08 ± 7.51 min, and 70.34 ± 8.03 min. The T1 of the SLE patients was shorter (p < 0.01), while the T3 was longer (p < 0.001). Moreover, T3 in the SLE group had the best correlation with the upper gastrointestinal symptom index (r = 0.553, p < 0.001). T1 in the SLE group was anti-correlated with early satiety (r = -0.366, p < 0.05). Combining the emptying times T1 and T3, as well as the gastric wall thickness, the SLEDAI and the upper gastrointestinal symptoms index can provide accurate clinical diagnosis of SLE with gastric involvement.

Complications of gastro-oesophageal reflux disease.

2013-06-01

Gastro-oesophageal reflux disease (GORD) is on the rise with more than 20% of the western population reporting symptoms and is the most common gastrointestinal disorder in the United States. This increase in GORD is not exactly clear but has been attributed to the increasing prevalence of obesity, changing diet, and perhaps the decreasing prevalence of H. pylori infection. Complications of GORD could be either benign or malignant. Benign complications include erosive oesophagitis, bleeding and peptic strictures. Premalignant and malignant lesions include Barrett's metaplasia, and oesophageal cancer. Management of both the benign and malignant complications can be challenging. With the use of proton-pump inhibitors, peptic strictures (i.e., strictures related to reflux) have significantly declined. Several aspects of Barrett's management remain controversial including the stage in the disease process which needs to be intervened, type of the intervention and surveillance of these lesions to prevent development of high grade dysplasia and oesophageal adenocarcinoma.

Background and study aims Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene, characterized by the presence of more than 100 adenomatous polyps in the colorectum. The upper gastrointestinal tract is an extracolonic site for malignancy in patients with FAP. The frequency of death in Japanese patients with FAP because of gastric cancer is 2.8 % and that because of colon cancer is 60.6 %. Few studies have reported upper gastrointestinal diseases in patients with FAP. In the present study, we investigated the clinical outcomes of patients with FAP diagnosed with gastric neoplasms. Patients and methods We enrolled 80 patients with FAP who underwent esophagogastroduodenoscopy from October 1997 to December 2011. We investigated patient characteristics, endoscopic findings of gastric lesions, treatment outcomes, and long-term courses. Results Fundic gland polyposis was observed in 51 patients (64 %) and gastric neoplasms in 22 patients (28 %), including 20 with non-invasive and 2 with invasive neoplasm. Of the 26 neoplasms, 11 were treated by endoscopic resection (ER) and 4 by surgical resection. Metachronous gastric neoplasms were observed in 7 patients (15 lesions) and treated by ER, except for in 1 patient. No patients died of gastric lesions during a median follow-up period of 6.5 years (range, 0 – 14). Conclusion Because gastric lesions including gastric cancers in patients with FAP did not cause any deaths, they can be considered to have favorable prognoses. Early detection of gastric neoplasms through an appropriate follow-up interval may have contributed to these good outcomes. PMID:28271094

Upper Gastrointestinal Involvement in Crohn Disease: Histopathologic and Endoscopic Findings.

2015-11-01

Studies describing the prevalence of upper gastrointestinal (GI) Crohn disease (CD) and its histopathologic changes have been inconsistent as a result of different definitions used for upper GI involvement, diverse populations, and varying indications for endoscopy. We reviewed the literature describing endoscopic findings and histologic lesions in gastric and duodenal mucosa of patients with established CD. PubMed, EMBASE, and the Cochrane Library were searched for gastroduodenal biopsy findings in patients with CD from 1970 to 2014. We included all retrospective and prospective studies in adults. We calculated the prevalence of the most common endoscopic and histopathological findings among patients with overall CD and upper GI CD. Of the 385 articles identified, 20 eligible studies were included. A total of 2511 patients had CD and 815 had upper GI CD. In the CD group, the most common histopathological finding was nonspecific gastric inflammation in 32% of patients, followed by gastric granuloma in 7.9%. Focal gastritis was prevalent in 30.9% of patients. In the upper GI CD group, gastric inflammation was present in 84% of patients, followed by duodenal inflammation in 28.2% and gastric granuloma in 23.2%. The most common gastric endoscopic finding in patients with CD was erythema in 5.9%, followed by erosions in 3.7%. Duodenal endoscopic findings included ulcers and erythema in 5.3% and 3.0% of patients, respectively. We found a prevalence of 34% for CD involving the upper GI tract across these 20 studies. Routine upper endoscopy with biopsies of the upper GI tract in the diagnostic workup of patients with CD can correctly classify the distribution and extent of the disease.

Etiological and Endoscopic Profile of Middle Aged and Elderly Patients with Upper Gastrointestinal Bleeding in a Tertiary Care Hospital in North India: A Retrospective Analysis.

Upper gastrointestinal (GI) bleeding is a common medical emergency associated with significant morbidity and mortality. The clinical presentation depends on the amount and location of hemorrhage and the endoscopic profile varies according to different etiology. At present, there are limited epidemiological data on upper GI bleed and associated mortality from India, especially in the middle and elderly age group, which has a higher incidence and mortality from this disease. This study aims to study the clinical and endoscopic profile of middle aged and elderly patients suffering from upper GI bleed to know the etiology of the disease and outcome of the intervention. Out of a total of 1790 patients who presented to the hospital from May 2015 to August 2017 with upper GI bleed, and underwent upper GI endoscopy, data of 1270 patients, aged 40 years and above, was compiled and analyzed retrospectively. All the patients included in the study were above 40 years of age. Majority of the patients were males, with a male to female ratio of 1.6:1. The most common causes of upper GI bleed in these patients were portal hypertension-related (esophageal, gastric and duodenal varices, portal hypertensive gastropathy, and gastric antral vascular ectasia GAVE), seen in 53.62% of patients, followed by peptic ulcer disease (gastric and duodenal ulcers) seen in 17.56% of patients. Gastric erosions/gastritis accounted for 15.20%, and duodenal erosions were seen in 5.8% of upper GI bleeds. The in-hospital mortality rate in our study population was 5.83%. The present study reported portal hypertension as the most common cause of upper GI bleeding, while the most common endoscopic lesions reported were esophageal varices, followed by gastric erosion/gastritis, and duodenal ulcer.

Although gastrointestinal tract bleeding can occur at any age, most studies trying to establish causes or risk factors for its development have been conducted in adults. The aim of this study was to determine risk factors in children admitted in a pediatric intensive care unit. A retrospective case-control study was conducted. Children who developed upper gastrointestinal bleeding children during their stay at the intensive care unit were considered the cases. Variables were obtained from medical records including age, sex, nutritional status, mechanical ventilation, use of nasogastric tube, development of complications, presence of coagulopathy, use of prophylaxis for upper gastrointestinal tract bleeding, fasting and use of steroids. Using a multivariate analysis, risk factors were identified, with odds ratios (OR) and 95 % confidence intervals (95 % CI) calculations. Out of 165 patients, 58 had upper gastrointestinal bleeding (35 %). Risk factors identified were prolonged clotting times (OR = 3.35), thrombocytopenia (OR = 2.39), development of sepsis (OR = 6.74) or pneumonia (OR = 4.37). Prophylaxis for upper gastrointestinal bleeding was not a protective factor. Upper gastrointestinal bleeding frequency in children hospitalized in an intensive care unit was high. Identifying risk factors should help to reduce upper gastrointestinal bleeding frequency.

Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features.Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated.In total, 70.2% of patients were female, median age 55 years (range 17-83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age <55 years (OR 1.6 [CI:1-2.5]), absence of smoking habit (OR 2.2 [CI:1.2-4]), and absence of anemia (OR 3.1 [CI:1.5-6.4]) were independent factors associated to dyspepsia.Autoimmune gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age <55 years (OR 1.6 [CI:1–2.5]), absence of smoking habit (OR 2.2 [CI:1.2–4]), and absence of anemia (OR 3.1 [CI:1.5–6.4]) were independent factors associated to dyspepsia. Autoimmune gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia.

From 1983 to 1994 Phase II and III clinical studies at Henry Ford Hospital demonstrated complete or partial responses in 46 of 47 patients treated with hematoporphyrin-derivative photodynamic therapy (HPD-PDT) for a variety of benign and malignant upper aerodigestive tract disease: (1) superficial `condemned mucosa' or `field cancerization' of the oral cavity; (2) stage III/IV head and neck cancer; (3) mucocutaneous AIDS-related Kaposi's sarcoma of the upper aerodigestive tract; (4) recurrent laryngotracheal papillomatosis; (5) severe dysplasia/adenocarcinoma in situ in Barrett's esophagus; (6) partial or completely obstructing terminal esophageal cancer. HPD-PDT produced complete responses in 19 patients (follow up 6 months to 8 years) with `field cancerization' (CIS, T1) of the oral cavity and larynx (6), adenocarcinoma in situ in Barrett's esophagus (2), mucocutaneous Kaposi's sarcoma (9), obstructing esophageal carcinoma (1), and stage IV squamous cell carcinoma of the nasopharynx (1). PDT treatment protocols, results, complications, and application as adjunct or primary oncologic therapy for head and neck disease are reviewed.

Gastro-oesophageal reflux disease (GORD) is the pathological reflux of gastric contents into the oesophagus. The oesophagus and the upper respiratory tract have a common origin from the foregut. There is increasing evidence for multiple associations of GORD with the upper respiratory tract. To study the presence of and association of upper respiratory symptoms (URS) with GORD. Seventy adults scoring ≥12.5 on a previously validated GORD symptom score (GORD patients) and 70 healthy controls who had infrequent GORD symptoms or no upper gastro-intestinal complaints completed a pre-tested URS questionnaire on the frequency of 14 URS in 5 categories (laryngeal, nasal, pharyngeal, sinusal and aural). All GORD patients underwent upper gastro-intestinal endoscopy. The calculated URS score was correlated against the GORD symptom score and endoscopy findings. URS scores and individual symptom scores were higher in GORD patients compared to controls (mean ± SE, 4.7 ± 4.0; 1.9 ± 2.3). Individuals with higher GORD symptom scores reported more frequent URS. Pharyngeal symptoms had the highest correlation with the GORD symptom score (r=0.507, p<0.001). The presence of oeso-phagitis did not seem to influence the frequency of reporting URS. Upper respiratory symptoms are common in individuals with GORD symptoms though there appears to be no association with oesophageal mucosal damage.

Inflammatory bowel disease (IBD) is characterized by recurrent or chronic inflammation of the gastrointestinal tract, which results in increased risk of developing cancer. Anorectal malignant melanoma is often misdiagnosed as either hemorrhoids or benign anorectal conditions in inflammatory bowel disease. Therefore, the overall prognosis and survival of IBD are poor. To date, the best treatment strategy remains controversial. Only early diagnosis and complete excision yield survival benefit. Here, we report a 64-year-old woman with ulcerative colitis, who was found to have anal malignant melanoma on routine colonoscopy. The lesion was confined to the mucosa with no distant metastasis. She underwent complete trans-anal excision. There was no recurrence at the four-year follow-up. Physicians should be aware of increased risk of cancer development in IBD patients and remember the importance of meticulous inspection of the anal canal.

To investigate the self-evaluation of upper gastrointestinal symptoms in Chinese patients. To observe the role of patients' characters, such as sex, age, education background, and clinic visits, which might affect the self-understanding of patients. The nationwide cross-sectional questionnaire was administered to 3000 patients with upper gastrointestinal symptoms at 50 hospitals across 9 provinces in China. Questionnaire items covered four basic patients' characters and five major upper gastrointestinal symptoms. A total of 2799 questionnaires (response rate: 93.3%) were analyzed. Only 35.29% patients could precisely understand the definition of dyspepsia. The misunderstanding of lower-gastroenterology discomforts is the major reason leading to low accuracy rate of dyspepsia. The accuracy rate of early satiety and postprandial fullness is 37.7% and 52.27% separately; they are most interrelated and easily confused concepts to each other. The accuracy rate of heartburn is 30.02%, while the location of burning sensation is the key aspect for misunderstanding of heartburn. The self-understanding of symptoms in patients was decreased with increasing age, and enhanced with higher education background and time of clinic visits. Gender is not the independent factor. Based on the low accuracy rate of self-understanding of patients, this survey suggests that the gastroenterologists should re-evaluate the symptoms of patients during the clinical inquiry. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Primary small-bowel malignancy: update in tumor biology, markers, and management strategies.

Primary small-bowel malignancies (SBM) are rare tumors but their incidence is rising. An estimated 9160 new cases and 1210 deaths due to SBM may occur in the USA in 2014. We review advances made in tumor biology, immunohistochemistry, and discuss treatment strategies for these malignancies. Relevant articles from PubMed/Medline and Embase searches were collected using the phrases "small-bowel adenocarcinoma, gastrointestinal carcinoids, gastrointestinal stromal tumors, small-bowel leiomyosarcoma, and small-bowel lymphoma". Advances in imaging techniques such as wireless capsule endoscopy, CT and MRI enterography, and endoscopy (balloon enteroscopy) along with discovery of molecular markers such as c-kit and PDGFRA for GIST tumors have improved our ability to diagnose, localize, and treat these patients. Early detection and surgical resection offers the best chance for long-term survival in all tumors except bowel lymphoma where chemotherapy plays the main role. Adjuvant therapy with imatinib has improved overall survival for GIST tumors, somatostatin analogs have improved symptoms and also inhibited tumor growth and stabilized metastatic disease in carcinoid disease, but chemotherapy has not improved survival for adenocarcinoma. Recent advances in molecular characterization holds promise in novel targeted therapies. Currently ongoing trials are exploring efficacy of targeted therapies and role of adjuvant therapy for adenocarcinoma and results are awaited. Early detection and aggressive surgical therapy for all localized tumors and lymph node sampling particularly for adenocarcinoma remains the main treatment modality.

Role of microRNA-7 in digestive system malignancy.

There are several malignancies of the digestive system (including gastric, pancreatic and colorectal cancers, and hepatocellular carcinoma), which are the most common types of cancer and a major cause of death worldwide. MicroRNA (miR)-7 is abundant in the pancreas, playing an important role in pancreatic development and endocrine function. Expression of miR-7 is downregulated in digestive system malignancies compared with normal tissue. Although there are contrasting results for miR-7 expression, almost all research reveals that miR-7 is a tumor suppressor, by targeting various genes in specific pathways. Moreover, miR-7 can target different genes simultaneously in different malignancies of the digestive system. By acting on many cytokines, miR-7 is also involved in many gastrointestinal inflammatory diseases as a significant carcinogenic factor. Consequently, miR-7 might be a biomarker or therapeutic target gene in digestive system malignancies.

[Gastrointestinal bleeding in the elderly].

Glaser, J

2014-08-01

Peptic ulcer disease is a common cause of gastrointestinal bleeding, independent of the patient's age. With advancing age, an increase of lower gastrointestinal bleeding (diverticula, angiodysplasia) has been observed. The administration of non-steroidal anti-inflammatory drugs and aspirin is an important risk factor for upper and lower gastrointestinal bleeding, thus in patients aged 65 years and more a concomitant therapy with proton pump inhibitors is recommended in order to prevent ulcer bleeding. Even in very old individuals endoscopy should be used for the diagnosis of gastrointestinal bleeding, providing the opportunity for definite endoscopic bleeding therapy. In elderly patients with comorbidities and recurrent bleeding after endoscopic therapy or continuous blood loss, surgery or transarterial embolisation should be considered in good time.

SUMMARY Diagnosis of focal disease, the theory that the human oral microbial (HOM) could affect the onset and development of systemic diseases, was very popular in the past, but the lack of scientific evidence has led to the abandonment of this idea. Interestingly, increasing evidence over the past 3 or so decades suggests that HOM can indeed serve as a reservoir for systemic dissemination of pathogenic bacteria and their toxins in distant body sites, favouring the developments of malignant tumours. Malignant tumours are complex communities of oncogenically transformed cells with aberrant genomes, associated non-neoplastic cells including immune and stromal cells, and sometimes HOM, including bacteria and viruses. Recent data suggest that HOM and periodontal disease play an active role in the pathogenesis of colorectal cancer, in fact HOM has been found within the colorectal cancer microenvironment, and the composition of the HOM was different from that of adjacent non-neoplastic tissue. An association of fusobacterium nucleatum with the colonic mucosa of colorectal cancer has been proven. Several questions thus arise. Is periodontal disease a risk factor for colorectal carcinoma? Given the connectivity of the digestive tract, could fusubacterium nucleatum or other HOM be involved in additional gastrointestinal disorders? Furthermore, based on the “mobility” of Fusubacterium nucleatum and the omnipresence of cadherins, could this organism be involved in cancers beyond the gastrointestinal tract? Answers to these questions will shed new lights on the role of the HOM in onset of diseases. PMID:29285324

Familial adenomatous polyposis is associated with a high incidence of malignancies in the upper gastrointestinal tract (particularly ampullary adenocarcinomas). However, few reports have described a correlation between familial adenomatous polyposis and gallbladder neoplasms. We present a case of a 60-year-old woman with familial adenomatous polyposis who presented with an elevated mass in the neck of the gallbladder (measuring 16 mm × 8 mm in diameter) and multiple small cholecystic polyps. She had undergone a total colectomy for ascending colon cancer associated with familial adenomatous polyposis 22 years previously. The patient underwent laparoscopic cholecystectomy under a preoperative diagnosis of multifocal gallbladder polyps. Pathologic examination of the resected gallbladder revealed more than 70 adenomatous lesions, a feature consistent with adenoma of the gallbladder. This case suggests a requirement for long-term surveillance of the biliary system in addition to the gastrointestinal tract in patients with familial adenomatous polyposis.

Background Transnasal endoscopy (TNE) is performed with an ultrathin scope via the nasal passages and is increasingly used. This review covers the technical characteristics, tolerability, safety and acceptability of TNE and also diagnostic accuracy, use as a screening tool and therapeutic applications. It includes practical advice from an ear, nose, throat (ENT) specialist to optimise TNE practice, identify ENT pathology and manage complications. Methods A Medline search was performed using the terms “transnasal”, “ultrathin”, “small calibre”, “endoscopy”, “EGD” to identify relevant literature. Results There is increasing evidence that TNE is better tolerated than standard endoscopy as measured using visual analogue scales, and the main area of discomfort is nasal during insertion of the TN endoscope, which seems remediable with adequate topical anaesthesia. The diagnostic yield has been found to be similar for detection of Barrett's oesophagus, gastric cancer and GORD-associated diseases. There are some potential issues regarding the accuracy of TNE in detecting small early gastric malignant lesions, especially those in the proximal stomach. TNE is feasible and safe in a primary care population and is ideal for screening for upper gastrointestinal pathology. It has an advantage as a diagnostic tool in the elderly and those with multiple comorbidities due to fewer adverse effects on the cardiovascular system. It has significant advantages for therapeutic procedures, especially negotiating upper oesophageal strictures and insertion of nasoenteric feeding tubes. Conclusions TNE is well tolerated and a valuable diagnostic tool. Further evidence is required to establish its accuracy for the diagnosis of early and small gastric malignancies. There is an emerging role for TNE in therapeutic endoscopy, which needs further study. PMID:28839865

- Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. - To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. - Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. - Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. - Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

The incidence of gastrointestinal disorders among patients with chronic kidney disease (CKD) is high, despite the lack of a good correlation between endoscopic findings and symptoms. Many services thus perform upper gastrointestinal (UGI) endoscopy on kidney transplant candidates. This study aims to describe the alterations seen on the upper endoscopies of 96 kidney-transplant candidates seen from 2014 to 2015. Ninety-six CKD patients underwent upper endoscopic examination as part of the preparation to receive kidney grafts. The data collected from the patients' medical records were charted on Microsoft Office Excel 2016 and presented descriptively. Mean values, medians, interquartile ranges and 95% confidence intervals of the clinic and epidemiological variables were calculated. Possible associations between endoscopic findings and infection by H. pylori were studied. Males accounted for 54.17% of the 96 patients included in the study. Median age and time on dialysis were 50 years and 50 months, respectively. The most frequent upper endoscopy finding was enanthematous pangastritis (57.30%), followed by erosive esophagitis (30.20%). Gastric intestinal metaplasia and peptic ulcer were found in 8.33% and 7.30% of the patients, respectively. H. pylori tests were positive in 49 patients, and H. pylori infection was correlated only with non-erosive esophagitis (P = 0.046). Abnormal upper endoscopy findings were detected in all studied patients. This study suggested that upper endoscopy is a valid procedure for kidney transplant candidates. However, prospective studies are needed to shed more light on this matter.

Gastrointestinal stromal tumor is a rare pathology. GISTs account for 0.3-1% of all tumors of the gastrointestinal tract. At the same time, this type of cancer is the most common, malignant, non-epithelial tumor of the gastrointestinal tube. Over 90% of GISTs are found in the stomach and small intestine. This cancer usually develops without characteristic clinical symptoms and is diagnosed incidentally. This clinical situation, in which the first symptom of a GIST-pattern tumor includes a fully-symptomatic, non-complicated umbilical hernia, is an unprecedented anomaly. This work presents a case report of a 77-year old female patient undergoing elective surgery, in which the contents of the hernial sac included a stromal tumor. Disseminated, multi-focal progression of the disease was found intraoperatively. Postoperative histopathology and immunohistochemistry revealed a gastrointestinal stromal tumor GIST of the spindle cell type, showing a CD-117, CD-34, SMA expression with possible starting point in the small intestine.

Coeliac disease: review of diagnosis and management.

Walker, Marjorie M; Ludvigsson, Jonas F; Sanders, David S

2017-08-21

Coeliac disease is an immune-mediated systemic disease triggered by exposure to gluten, and manifested by small intestinal enteropathy and gastrointestinal and extra-intestinal symptoms. Recent guidelines recommend a concerted use of clear definitions of the disease. In Australia, the most recent estimated prevalence is 1.2% in adult men (1:86) and 1.9% in adult women (1:52). Active case finding is appropriate to diagnose coeliac disease in high risk groups. Diagnosis of coeliac disease is important to prevent nutritional deficiency and long term risk of gastrointestinal malignancy. The diagnosis of coeliac disease depends on clinico-pathological correlation: history, presence of antitransglutaminase antibodies, and characteristic histological features on duodenal biopsy (when the patient is on a gluten-containing diet). Human leucocyte antigen class II haplotypes DQ2 or DQ8 are found in nearly all patients with coeliac disease, but are highly prevalent in the general population at large (56% in Australia) and testing can only exclude coeliac disease for individuals with non-permissive haplotypes. Adhering to a gluten free diet allows duodenal mucosal healing and alleviates symptoms. Patients should be followed up with a yearly review of dietary adherence and a health check. Non-coeliac gluten or wheat protein sensitivity is a syndrome characterised by both gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten and possibly other wheat proteins in people who do not have coeliac disease or wheat allergy recognised by diagnostic tests.

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

Update on imaging of Peutz-Jeghers syndrome

2014-01-01

Peutz-Jeghers syndrome (PJS) is a rare, autosomal dominant disease linked to a mutation of the STK 11 gene and is characterized by the development of benign hamartomatous polyps in the gastrointestinal tract in association with a hyperpigmentation on the lips and oral mucosa. Patients affected by PJS have an increased risk of developing gastrointestinal and extra-digestive cancer. Malignancy most commonly occurs in the small-bowel. Extra-intestinal malignancies are mostly breast cancer and gynecological tumors or, to a lesser extent, pancreatic cancer. These polyps are also at risk of acute gastrointestinal bleeding, intussusception and bowel obstruction. Recent guidelines recommend regular small-bowel surveillance to reduce these risks associated with PJS. Small-bowel surveillance allows for the detection of large polyps and the further referral of selected PJS patients for endoscopic enteroscopy or surgery. Video capsule endoscopy, double balloon pushed enteroscopy, multidetector computed tomography and magnetic resonance enteroclysis or enterography, all of which are relatively new techniques, have an important role in the management of patients suffering from PJS. This review illustrates the pathological, clinical and imaging features of small-bowel abnormalities as well as the role and performance of the most recent imaging modalities for the detection and follow-up of PJS patients.

2014-04-28

Invasive micropapillary carcinoma (IMPC) is a rare histological type of tumor, first described in invasive ductal breast cancer, than in malignancies in other organs such as lungs, urinary bladder, ovaries or salivary glands. Recent literature data shows that this histological lesion has also been found in cancers of the gastrointestinal system. The micropapillary components are clusters of neoplastic cells that closely adhere to each other and are located in distinct empty spaces. Moreover, clusters of neoplastic cells do not have a fibrous-vascular core. The IMPC cells show reverse polarity resulting in typical ''inside-out'' structures that determines secretary properties, disturbs adhesion and conditions grade of malignancy in gastrointestinal (GI) tract. Invasive micropapillary carcinoma in this location is associated with metastases to local lymph nodes and lymphovascular invasion. IMPC can be a prognostic factor for patients with cancers of the stomach, pancreas and with colorectal cancer since it is related with disease-free and overall survival. The purpose of this review is to present the characterization of invasive micropapillary carcinoma in colon, rectum, stomach and others site of GI tract, and to determine the immunohistological indentification of IMPC in those localization.

Objective The incidence of the upper gastrointestinal tumor has increased rapidly during recent decades. The relationship between local water pollution and the tumor is still not much clear, so this study was conducted to further investigate the local water pollution and its influence on the malignant cell transformation. Prevalence of human papillomavirus (HPV) in local esophageal cancer (EC) patients was also analyzed in Shenqiu County for the first time. Methods Two-step cell transformation was used to study different sources of water in the malignant cell transformation, and the existence of 3-methylcholanthrene (3-MC) in water was analyzed from the river and shallow and deep wells. HPV DNA in tissue samples of EC patients was detected by polymerase chain reaction (PCR) and HPV diagnostic kit. Results The river water has higher cytotoxicity than the shallow well water and induced significant cell malignant transformation, while deep well water has not shown the malignant cell transformation. In Huaihe River water, the 3-MC concentration was found higher than shallow and deep wells. An HPV infection rate was found high in patients with esophageal cancer. Conclusion Long-term consumption of polluted water can induce malignant cell transformation, and the presence of HPV may be an important cause of cancer. PMID:29853858

The goals of the study were to determine the relationship of upper gastrointestinal symptoms with nutritional status and to assess their association with performance status in patients with advanced cancer. We studied 143 patients (50 F, 93 M, mean age 68 +/- 11 years, mean body mass index 22.39 +/- 4.3 kg/m(2)). Assessed symptoms were the following: anorexia, nausea, vomiting, dysphagia for solids, dysphagia for liquids, xerostomia, hypogeusia, dysgeusia, hiccup and chewing disturbances. We determined anthropometric parameters, daily energy intake and serum albumin, prealbumin and transferrin. The most common upper gastrointestinal symptoms were xerostomia (73%), anorexia (49%) and chewing disturbances (40%). Fifty-four percent of patients had weight loss greater than 10%. Seventy-three patients (51%) had daily energy intake lower than their resting energy expenditure. Mean serum prealbumin, albumin and transferrin were below normal range. Mean Eastern Cooperative Oncology Group performance status scale was 3.1 +/- 0.49. Symptoms were often strongly correlated, and usually, patients experienced at least three upper gastrointestinal symptoms at the same time. Anorexia, nausea and vomiting were the symptoms mostly correlated with other symptoms. A correlation was found between vomiting and hiccup. Energy intake (EI) was the nutritional parameter mostly affected by upper gastrointestinal symptoms; moreover, EI is the most predictive factor of upper gastrointestinal symptoms, particularly xerostomia, anorexia and dysphagia for solids. Upper gastrointestinal symptoms are linked to nutritional parameters: In particular, energy intake represents the most predictive variable of symptom occurrence. The performance status is not affected by upper gastrointestinal symptoms. A rigorous nutritional assessment and the managing of upper gastrointestinal symptoms are crucial in patients with advanced cancer.

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has become increasingly popular for the diagnosis and staging of gastrointestinal diseases and peri-gastrointestinal lesions. The application of FNA/Brush has dramatically expanded the clinical utility of EUS. To evaluate the diagnostic accuracy, study the spectrum of lesions encountered in EUS-FNAC/brush cytology of gastrointestinal and peri-gastrointestinal lesions. Total of 124 patients during the period from August 2015 to November 2016 was included in the study. Routine staining was done. A total of 124 cases were studied with 86% (107 cases) being satisfactory for evaluation. M:F ratio was 1:1.03, mean age of 50.5 years. The most common site was common bile duct (CBD) (37%) followed by lymph node (21%), pancreas (17.7%), esophagus (17%), stomach (3.5%), liver (1.8%), gallbladder (1%), and spleen (1%). In total, 53.4% lesions were benign, in 6.5% atypical cells were seen, 12.1% were suspicious for malignancy, and 28% cases were positive for malignancy. Follow-up was available in 102 cases with cyto-histopathological concordance rate of 90%. EUS-FNA/Brush is a reliable, sensitive, specific and minimally invasive way to establish a diagnosis. It can be utilized as a pre-operative procedure for the management of many intra-abdominal lesions and prevent unnecessary invasive procedures. © 2018 Wiley Periodicals, Inc.

Lactase is an enzyme involved in the hydrolysis of lactose. Deficiency of the enzyme (hypolactasia) may be determined genetically or arise secondarily to disease of small intestine. Under this condition, lactose enters the colon where it is fermented by intestinal microflora and turns to gases and short-chain fatty acids, causing gastrointestinal symptoms known as lactose intolerance (LI). To investigate the incidence of lactose malabsorption (LM), LI and the coexistence of these two conditions in children with upper gastrointestinal tract diseases (UGTD), malabsorption syndrome, inflammatory bowel disease (IBD) and functional gastrointestinal disorders (FGID). Hydrogen breath test (HBT) was conducted in 387 pediatric patients in years 2010-2013. Two hundred thirty two children with gastrointestinal tract diseases were selected and assigned to groups - UGTD, malabsorption syndrome, IBD or FGID. For each group the frequency of LM, frequency and severity of LI and the frequency of their co-occurrence were calculated. Lactose malabsorption was observed in 37.08% of patients with gastrointestinal diseases. Positive HBT result was the most common in children with malabsorption syndrome (52.50%) and less common in UGTD (30.85%), especially in ulcer disease (23.53%). Symptoms after lactose ingestion affected 36.64% of the subjects, and were more specific to lactose malabsorbers than to lactose absorbers (72.10% vs. 15.75%). The higher frequency of LI was noted in children with FGID, especially in irritable bowel syndrome (IBS) (65.22%). The lowest incidence of symptoms was obtained in children with UGTD, especially in those with ulcer disease (27.44%). The incidence of LM with LI was noted in 27.16% of all patients and was the highest in IBS (47.83%) and the lowest in ulcer disease (15.78%). Lactose malabsorption is a common problem in children with gastrointestinal diseases, especially in children with bowel diseases. Lactose intolerance is related to LM, but does not affect all malabsorbers.

To evaluate the accuracy of disease codes and free text in identifying upper gastrointestinal bleeding (UGIB) from electronic health-care records (EHRs). We conducted a validation study in four European electronic health-care record (EHR) databases such as Integrated Primary Care Information (IPCI), Health Search/CSD Patient Database (HSD), ARS, and Aarhus, in which we identified UGIB cases using free text or disease codes: (1) International Classification of Disease (ICD)-9 (HSD, ARS); (2) ICD-10 (Aarhus); and (3) International Classification of Primary Care (ICPC) (IPCI). From each database, we randomly selected and manually reviewed 200 cases to calculate positive predictive values (PPVs). We employed different case definitions to assess the effect of outcome misclassification on estimation of risk of drug-related UGIB. PPV was 22% [95% confidence interval (CI): 16, 28] and 21% (95% CI: 16, 28) in IPCI for free text and ICPC codes, respectively. PPV was 91% (95% CI: 86, 95) for ICD-9 codes and 47% (95% CI: 35, 59) for free text in HSD. PPV for ICD-9 codes in ARS was 72% (95% CI: 65, 78) and 77% (95% CI: 69, 83) for ICD-10 codes (Aarhus). More specific definitions did not have significant impact on risk estimation of drug-related UGIB, except for wider CIs. ICD-9-CM and ICD-10 disease codes have good PPV in identifying UGIB from EHR; less granular terminology (ICPC) may require additional strategies. Use of more specific UGIB definitions affects precision, but not magnitude, of risk estimates. Copyright © 2014 Elsevier Inc. All rights reserved.

Upper gastrointestinal bleeding implies significant clinical and economic repercussions. The correct establishment of the latest therapies for the upper gastrointestinal bleeding is associated with reduced in-hospital mortality. The use of clinical pathways for the upper gastrointestinal bleeding is associated with shorter hospital stay and lower hospital costs. The primary objective is the development of a clinical care pathway for the management of patients with upper gastrointestinal bleeding, to be used in tertiary hospital. It was conducted an extensive literature review on the management of upper gastrointestinal bleeding, contained in the primary and secondary information sources. The result is a clinical care pathway for the upper gastrointestinal bleeding in patients with evidence of recent bleeding, diagnosed by melena or hematemesis in the last 12 hours, who are admitted in the emergency rooms and intensive care units of tertiary hospitals. In this compact and understandable pathway, it is well demonstrated the management since the admission, with definition of the inclusion and exclusion criteria, passing through the initial clinical treatment, posterior guidance for endoscopic therapy, and referral to rescue therapies in cases of persistent or rebleeding. It was also included the care that must be taken before hospital discharge for all patients who recover from an episode of bleeding. The introduction of a clinical care pathway for patients with upper gastrointestinal bleeding may contribute to standardization of medical practices, decrease in waiting time for medications and services, length of hospital stay and costs.

To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

In several organ systems the transitional zone between different types of epithelia is a hotspot for pre-neoplastic metaplasia and malignancy1–3. However, the cell-of-origin for the metaplastic epithelium and subsequent malignancy, remains obscure1–3. In the case of Barrett’s oesophagus (BE), intestinal metaplasia occurs at the gastro-oesophageal junction, where stratified squamous epithelium transitions into simple columnar cells4. Based on different experimental models, several alternative cell types have been proposed as the source of the metaplasia, but in all cases the evidence is inconclusive and no model completely mimics BE with the presence of intestinal goblet cells5–8. Here, we describe a novel transitional columnar epithelium with distinct basal progenitor cells (p63+ KRT5+ KRT7+) in the squamous-columnar junction (SCJ) in the upper gastrointestinal tract of the mouse. We use multiple models and lineage tracing strategies to show that this unique SCJ basal cell population serves as a source of progenitors for the transitional epithelium. Moreover, upon ectopic expression of CDX2 these transitional basal progenitors differentiate into intestinal-like epithelium including goblet cells, thus reproducing Barrett’s metaplasia. A similar transitional columnar epithelium is present at the transitional zones of other mouse tissues, including the anorectal junction, and, importantly, at the gastro-oesophageal junction in the human gut. Acid reflux-induced oesophagitis and the multilayered epithelium (MLE) believed to be a precursor of BE are both characterized by the expansion of the transitional basal progenitor cells. Taken together our findings reveal the presence of a previously unidentified transitional zone in the epithelium of the upper gastrointestinal tract and provide evidence that the p63+ KRT7+ basal cells in this zone are the cell-of-origin for MLE and BE.

Foreign body ingestion is a relatively common occurrence, which may lead to morbidity and mortality. The aim of the present study was to report the experience of management of upper gastrointestinal foreign bodies by endoscopy in a large center. All patients who presented at the Department of Gastroenterology at Nanfang Hospital (Guangzhou, China) with complaints regarding upper gastrointestinal (GI) foreign body ingestion from December 1987 to December 2013. Hospital medical charts and endoscopic records were examined to evaluate etiology, treatment, and outcomes for these patients. A total of 846 patients were enrolled in the present study, from which foreign bodies were detected in 737 (87.1%) patients via X-ray or endoscopy. The objects most frequently ingested were bones (n=395, 53.6%). The detected foreign bodies were predominantly located in the cervical esophagus (n=325, 44.1%). Endoscopic foreign body extraction was successful in 92.5% of cases, whereas surgery was required in 6 patients. The most frequently used endoscopic accessory devices were retrieval forceps (n=480, 65.1%). The complication rate was 6.9%, including mucosal laceration (n=10) and others, all of which were managed conservatively. Associated GI diseases were reported in 74 (10.0%) patients, including postesophagectomy (n=34) and others. In conclusion, the endoscopic procedure was safe and effective for the removal of foreign bodies from the upper gastrointestinal tract, with a high success rate and low complication rate.

With proton pump inhibitors and current sophisticated endoscopic techniques, the number of patients requiring surgical intervention for upper gastrointestinal bleeding has decreased considerably while trans-arterial embolization is being used more often. There are few direct comparisons between the effectiveness of surgery and embolization. A retrospective study of patients from two Australian teaching hospitals who had surgery or trans-arterial embolization (n = 103) for severe upper gastrointestinal haemorrhage between 2004 and 2012 was carried out. Patient demographics, co-morbidities, disease pathology, length of stay, complications, and overall clinical outcome and mortality were compared. There were 65 men and 38 women. The median age was 70 (range 36-95) years. Patients requiring emergency surgical intervention (n = 79) or trans-arterial embolization (n = 24) were compared. The rate of re-bleeding after embolization (42%) was significantly higher compared with the surgery group (19%) (P = 0.02). The requirement for further intervention (either surgery or embolization) was also higher in the embolization group (33%) compared with the surgery group (13%) (P = 0.03). There was no statistical difference in mortality between the embolization group (5/24, 20.8%) and the surgical group (13/79, 16.5%) (P = 0.75). Emergency surgery and embolization are required in 2.6% of patients with upper gastrointestinal bleeding. Both techniques have high mortalities reflecting the age, co-morbidities and severity of bleeding in this patient group. © 2014 Royal Australasian College of Surgeons.

Treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin is associated with increased risk of upper gastrointestinal bleeding. There is little evidence on the risk of lower gastrointestinal bleeding with NSAIDs, antiplatelet agents (APAs), or anticoagulants. We aimed to quantify the relative risk (RR) of upper and lower gastrointestinal bleeding associated with use of NSAIDs, APAs, or anticoagulants. We performed a case-control study that used data collected from consecutive patients hospitalized for gastrointestinal bleeding (563 upper, mean age, 63.6 ± 16.7 years and 415 lower, mean age, 70.8 ± 13.8 years), confirmed by endoscopy or other diagnostic procedures. Unhospitalized patients were used as controls (n = 1008) and matched for age, hospital, and month of admission. Drug use was considered current when taken within 7 days or less before hospitalization. RRs and 95% confidence intervals (CIs) were estimated by unconditional logistic regression analysis. Use of anticoagulants, low-dose aspirin, and other drugs (non-aspirin-APA, 82.3% thienopiridines) was associated with upper and lower gastrointestinal bleeding; the risk was 2-fold higher for anticoagulants (RR, 4.2; 95% CI, 2.9-6.2) than for low-dose aspirin (RR, 2.1; 95% CI, 1.4-3.3) or other non-aspirin-APA drugs (RR, 2.0; 95% CI, 1.6-2.6). NSAID use was also associated with increased risk of gastrointestinal bleeding and greater for upper (RR, 2.6; 95% CI, 2.0-3.5) than lower gastrointestinal bleeding (RR, 1.4; 95% CI, 1.0-1.9). Use of proton pump inhibitors was associated with reduced risk of upper, but not lower, gastrointestinal bleeding. Anticoagulants, low-dose aspirin, NSAIDs, and other non-aspirin-APA drugs are associated with increased risk of upper and lower gastrointestinal bleeding. Use of anticoagulants appears to be the strongest risk factor for gastrointestinal bleeding. Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.

Gastric adenocarcinoma concurrent with paravertebral plasmacytoma: A case report

2016-01-01

Here, we report the case of a 77-year-old male patient who was revealed to have an unsuspected case of gastric adenocarcinoma with paravertebral plasmacytoma following biopsy. Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases. PMID:27446469

Acute lymphoblastic leukemia and lymphoma in the context of constitutional mismatch repair deficiency syndrome.

Ripperger, Tim; Schlegelberger, Brigitte

2016-03-01

Constitutional mismatch repair deficiency (CMMRD) syndrome is one of the rare diseases associated with a high risk of cancer. Causative mutations are found in DNA mismatch repair genes PMS2, MSH6, MSH2 or MLH1 that are well known in the context of Lynch syndrome. CMMRD follows an autosomal recessive inheritance trait and is characterized by childhood brain tumors and hematological malignancies as well as gastrointestinal cancer in the second and third decades of life. There is a high risk of multiple cancers, occurring synchronously and metachronously. In general, the prognosis is poor. About one third of CMMRD patients develop hematological malignancies as primary (sometimes the only) malignancy or as secondary neoplasm. T-cell non-Hodgkin lymphomas, mainly of mediastinal origin, are the most frequent hematological malignancies. Besides malignant diseases, non-neoplastic features are frequently observed, e.g. café-au-lait spots sometimes resembling neurofibromatosis type I, hypopigmented skin lesions, numerous adenomatous polyps, multiple pilomatricomas, or impaired immunoglobulin class switch recombination. Within the present review, we summarize previously published CMMRD patients with at least one hematological malignancy, provide an overview of steps necessary to substantiate the diagnosis of CMMRD, and refer to the recent most relevant literature.

Transcatheter arterial embolization (TAE) is a therapeutic option for endoscopically unmanageable upper gastrointestinal (GI) bleeding. We aimed to assess the efficacy and clinical outcomes of TAE for acute non-variceal upper GI bleeding and to identify predictors of recurrent bleeding within 30 days. Visceral angiography was performed in 66 patients (42 men, 24 women; mean age, 60.3 ± 12.7 years) who experienced acute non-variceal upper GI bleeding that failed to be controlled by endoscopy during a 7-year period. Clinical information was reviewed retrospectively. Outcomes included technical success rates, complications, and 30-day rebleeding and mortality rates. TAE was feasible in 59 patients. The technical success rate was 98%. Rebleeding within 30 days was observed in 47% after an initial TAE and was managed with re-embolization in 8, by endoscopic intervention in 5, by surgery in 2, and by conservative care in 12 patients. The 30-day overall mortality rate was 42.4%. In the case of initial endoscopic hemostasis failure (n = 34), 31 patients underwent angiographic embolization, which was successful in 30 patients (96.8%). Rebleeding occurred in 15 patients (50%), mainly because of malignancy. Two factors were independent predictors of rebleeding within 30 days by multivariate analysis: coagulopathy (odds ratio [OR] = 4.37; 95% confidence interval [CI]: 1.25-15.29; p = 0.021) and embolization in ≥2 territories (OR = 4.93; 95% CI: 1.43-17.04; p = 0.012). Catheterization-related complications included hepatic artery dissection and splenic embolization. TAE controlled acute non-variceal upper GI bleeding effectively. TAE may be considered when endoscopic therapy is unavailable or unsuccessful. Correction of coagulopathy before TAE is recommended.

Present guidelines are conflicting for patients at high risk of both cardiovascular and gastrointestinal events who continue to require non-steroidal anti-inflammatory drugs (NSAIDs). We hypothesised that a cyclooxygenase-2-selective NSAID plus proton-pump inhibitor is superior to a non-selective NSAID plus proton-pump inhibitor for prevention of recurrent ulcer bleeding in concomitant users of aspirin with previous ulcer bleeding. For this industry-independent, double-blind, double-dummy, randomised trial done in one academic hospital in Hong Kong, we screened patients with arthritis and cardiothrombotic diseases who were presenting with upper gastrointestinal bleeding, were on NSAIDs, and require concomitant aspirin. After ulcer healing, an independent staff member randomly assigned (1:1) patients who were negative for Helicobacter pylori with a computer-generated list of random numbers to receive oral administrations of either celecoxib 100 mg twice per day plus esomeprazole 20 mg once per day or naproxen 500 mg twice per day plus esomeprazole 20 mg once per day for 18 months. All patients resumed aspirin 80 mg once per day. Both patients and investigators were masked to their treatments. The primary endpoint was recurrent upper gastrointestinal bleeding within 18 months. The primary endpoint and secondary safety endpoints were analysed in the modified intention-to-treat population. This study was registered with ClinicalTrials.gov, number NCT00153660. Between May 24, 2005, and Nov 28, 2012, we enrolled 514 patients, assigning 257 patients to each study group, all of whom were included in the intention-to-treat population. Recurrent upper gastrointestinal bleeding occurred in 14 patients in the celecoxib group (nine gastric ulcers and five duodenal ulcers) and 31 patients in the naproxen group (25 gastric ulcers, three duodenal ulcers, one gastric ulcer and duodenal ulcer, and two bleeding erosions). The cumulative incidence of recurrent bleeding in 18 months was 5·6% (95% CI 3·3-9·2) in the celecoxib group and 12·3% (8·8-17·1) in the naproxen group (p=0·008; crude hazard ratio 0·44, 95% CI 0·23-0·82; p=0·010). Excluding patients who reached study endpoints, 21 (8%) patients in the celecoxib group and 17 (7%) patients in the naproxen group had adverse events leading to discontinuation of treatment. No treatment-related deaths occurred during the study. In patients at high risk of both cardiovascular and gastrointestinal events who require concomitant aspirin and NSAID, celecoxib plus proton-pump inhibitor is the preferred treatment to reduce the risk of recurrent upper gastrointestinal bleeding. Naproxen should be avoided despite its perceived cardiovascular safety. The Research Grant Council of Hong Kong. Copyright © 2017 Elsevier Ltd. All rights reserved.

Evaluations of upper gastrointestinal toxicity from ketamine abuse are uncommon. This study investigated the clinical pattern of upper gastrointestinal symptoms in patients inhaling ketamine. In a cross-sectional study of 611 consecutive patients who were seeking treatment for ketamine uropathy in a tertiary hospital setting between August 2008 and June 2016, their clinical pattern of upper gastrointestinal symptoms was evaluated and compared with a control population of 804 non-users. A total of 168 (27.5%) patients abusing ketamine (mean age 26.3 years, 58.9% female) reported the presence of upper gastrointestinal symptoms. These symptoms were significantly more prevalent in patients inhaling ketamine than in those who were not (27.5% vs 5.2%, P < 0.001). Their mean duration of ketamine abuse before symptom presentation was 5.0 ± 3.1 years. The presenting symptoms included epigastric pain (n = 155, 25.4%), recurrent vomiting (n = 48, 7.9%), anemia (n = 36, 5.9%) and gastrointestinal bleeding (n = 20, 3.3%). Uropathy symptoms were preceded by upper gastrointestinal symptoms for 4.4 ± 3.0 years in 141 (83.9%) patients. Logistic regression showed that elder age (odds ratio [OR] 1.06, P = 0.04), active abuser status (OR 1.60, P = 0.04) and longer duration of ketamine abuse (OR 1.00, P = 0.04) were independent factors associated with upper gastrointestinal toxicity. Although epigastric symptoms are unusual in the young population, upper gastrointestinal toxicity was highly prevalent in those inhaling ketamine. Enquiries about ketamine abuse are recommended when assessing young patients with epigastric symptoms. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Psoriasis is a common chronic inflammatory disease of the skin that is increasingly being recognized as a systemic inflammatory disorder. Psoriatic arthritis is a well-known comorbidity of psoriasis. A rapidly expanding body of literature in various populations and settings supports additional associations between psoriasis and cardiometabolic disease, gastrointestinal disease, kidney disease, malignancies, infections, and mood disorders. The pathogenesis of comorbid disease in psoriasis patients remains unknown; however, shared inflammatory pathways, cellular mediators, genetic susceptibility, and common risk factors are hypothesized to be contributing elements. As additional psoriasis comorbidities continue to emerge, education of healthcare providers is essential to ensuring comprehensive medical care for patients with psoriasis. PMID:28212759

Gene therapy and gastrointestinal cancer: concepts and clinical facts.

PubMed

Hauses, M; Schackert, H K

1999-10-01

Principles of the treatment of gastrointestinal cancer with gene therapy evolved from the advent of techniques in molecular biology, from increasing insights into the molecular basis of tumorigenesis and from the need to develop more efficient treatment modalities. Any gene therapy approach has to take two major tasks into consideration: the therapeutic gene has to be delivered into the target cell population with high efficiency, specificity and safety, and has to act in a way that provides a benefit to the patient. Data on 22 clinical trials on malignancies of the gastrointestinal tract are available. They utilize a variety of gene-delivery methods and target cell populations, and there is considerable variety among their strategies. Gene transfer is performed by injection of naked plasmid DNA and by use of DNA-liposome complexes and viral vectors. In some cases, the gene transfer is carried out ex vivo and the patients receive genetically modified cells, whereas other approaches deliver the vector to the target cell population in vivo. The theoretical concepts of gene therapy can be divided into three groups. One approach makes use of suicide genes comprising bacterial or viral genes that convert a nontoxic prodrug into a highly cytotoxic chemotherapeutic agent at the tumor site. This approach aims at higher therapeutic specificity and fewer side effects than with the systemic delivery of cytotoxic agents. The second strategy makes an attempt to invoke the immune system to destroy malignant cells. Different strategies, such as immunization with genetically modified tumor cells or transfer of new genes to T cells, are considered to have clinical benefits. The major advantage of these immunotherapeutic approaches is the systemic effect both on the primary tumor and on metastases. The third strategy evolved from the insight that cancer is a genetic disease caused by activation of oncogenes or inactivation of tumor-suppressor genes. Compensation of genetic defects by the downregulation of activated oncogenes or the restoration of tumor-suppressor-gene functions may be able to revert the malignant phenotype of cancer cells. Of the 22 gene-therapy trials, 17 trials focus on immunotherapy. Only two trials make use of suicide genes and, in three trials, a functional copy of the p53 tumor-suppressor gene was reintroduced into malignant cells. Modalities for gene transfer and the strategies underlying gene therapy will be discussed in the context of gastrointestinal malignancies and the potential benefits for patients.

An association between Helicobacter pylori and upper respiratory tract disease: Fact or fiction?

PubMed Central

Kariya, Shin; Okano, Mitsuhiro; Nishizaki, Kazunori

Helicobacter pylori (H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions. PMID:24587622

Physiology and pathophysiology of apoptosis in epithelial cells of the liver, pancreas, and intestine.

Cell death of gastrointestinal epithelial cells occurs by a process referred to as apoptosis. In this review, we succinctly define apoptosis and summarize the role of apoptosis in the physiology and pathophysiology of epithelial cells in the liver, pancreas, and small and large intestine. The physiological mediators regulating apoptosis in gastrointestinal epithelial cells, when known, are discussed. Selected pathophysiological consequences of excessive apoptosis and inhibition of apoptosis are used to illustrate the significance of apoptosis in disease processes. These examples demonstrate that excessive apoptosis may result in epithelial cell atrophy, injury, and dysfunction, whereas inhibition of apoptosis results in hyperplasia and promotes malignant transformation. The specific cellular mechanisms responsible for dysregulation of epithelial cell apoptosis during pathophysiological disturbances are emphasized. Potential future areas of physiological research regarding apoptosis in gastrointestinal epithelia are highlighted when appropriate.

We herein report a rare case of a massive upper gastrointestinal (GI) bleeding, caused by high-grade diffuse B-cell lymphoma of the duodenum, secondary to immunoproliferative small intestinal disease (IPSID) and treated with an emergency partial pancreatoduodenectomy. A 42-year-old man was admitted to our hospital because of hematemesis. Upper GI endoscopy was unrevealing because of the copious bleeding. Initially, the patient underwent conservative treatment, thus resulting in the temporary cessation of the bleeding. Later, the hemorrhage massively relapsed. An urgent abdominal ultrasound raised the suspicion of a large, possibly bleeding, neoplasm of the duodenum, which was finally confirmed by abdominal computed tomography. The patient underwent an emergency laparotomy, during which a partial pancreatoduodenectomy was performed (Whipple procedure). Histologically, the tumor was a high-grade B-cell lymphoma of the duodenum. The nearby small intestinal mucosa was suggestive of IPSID. A massive upper GI hemorrhage from a high-grade B-cell non-Hodgkin lymphoma of the duodenum, which develops secondary to IPSID, is a very rare clinical demonstration of this disease. Our case is one of the few reports in the English literature, for which the Whipple procedure has been performed as a curative treatment.

2014-12-01

We have recognized a unique clinical syndrome in patients with upper gastrointestinal bleeding who are found to have severe esophagitis. We aimed to more clearly describe the clinical entity of upper gastrointestinal bleeding in patients with severe esophagitis. We conducted a retrospective matched case-control study designed to investigate clinical features in patients with carefully defined upper gastrointestinal bleeding and severe esophagitis. Patient data were captured prospectively via a Gastrointestinal Bleeding Healthcare Registry, which collects data on all patients admitted with gastrointestinal bleeding. Patients with endoscopically documented esophagitis (cases) were matched with randomly selected controls that had upper gastrointestinal bleeding caused by other lesions. Epidemiologic features in patients with esophagitis were similar to those with other causes of upper gastrointestinal bleeding. However, hematemesis was more common in patients with esophagitis 86% (102/119) than in controls 55% (196/357) (p < 0.0001), while melena was less common in patients with esophagitis 38% (45/119) than in controls 68% (244/357) (p < 0.0001). Additionally, the more severe the esophagitis, the more frequent was melena. Patients with esophagitis had less abnormal vital signs, lesser decreases in hematocrit, and lesser increases in BUN. Both pre- and postRockall scores were lower in patients with esophagitis compared with controls (p = 0.01, and p < 0.0001, respectively). Length of hospital stay (p = 0.002), rebleeding rate at 42 days (p = 0.0007), and mortality were less in patients with esophagitis than controls. Finally, analysis of patients with esophagitis and cirrhosis suggested that this group of patients had more severe bleeding than those without cirrhosis. We have described a unique clinical syndrome in patients with upper gastrointestinal bleeding who have erosive esophagitis. This syndrome is manifest by typical clinical features and is associated with favorable outcomes.

Cases of primary gastric adenocarcinoma with metastasis to the breast are extremely rare. Till now, only 38 cases have been reported in PubMed since 1908. We herein reported a race case of gastric adenocarcinoma with metastasis to the right breast. Breast biopsy showed invasive signet-ring cell breast carcinoma in the right breast. She was given a TEC regimen (docetaxel 75 mg/m(2), epirubicin 75 mg/m(2), and cyclophosphamide 600 mg/m(2) every 3 weeks) for one cycle but showed no objective response. Upper gastrointestinal endoscopy demonstrated an ulcerative mass in the gastric body. Biopsy demonstrated low-grade gastric adenocarcinoma with signet-ring features. In immunohistochemistry, mammary malignant cells were positive for cytokeratin 7, cytokeratin 20, villin, and ErbB2/HER2, but negative for gross cystic disease fluid protein-15, estrogen receptor, and progesterone receptor. The diagnosis of metastatic poorly differentiated signet-ring cell adenocarcinoma of the right breast identical to gastric primary was confirmed finally. Gastric cancer with metastasis to the breast can be diagnosed by clinical history, histological findings, and immunohistochemical markers.

Imaging of non-neoplastic duodenal diseases. A pictorial review with emphasis on MDCT.

A wide spectrum of abnormalities can affect the duodenum, ranging from congenital anomalies to traumatic and inflammatory entities. The location of the duodenum and its close relationship with other organs make it easy to miss or misinterpret duodenal abnormalities on cross-sectional imaging. Endoscopy has largely supplanted fluoroscopy for the assessment of the duodenal lumen. Cross-sectional imaging modalities, especially multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI), enable comprehensive assessment of the duodenum and surrounding viscera. Although overlapping imaging findings can make it difficult to differentiate between some lesions, characteristic features may suggest a specific diagnosis in some cases. Familiarity with pathologic conditions that can affect the duodenum and with the optimal MDCT and MRI techniques for studying them can help ensure diagnostic accuracy in duodenal diseases. The goal of this pictorial review is to illustrate the most common non-malignant duodenal processes. Special emphasis is placed on MDCT features and their endoscopic correlation as well as on avoiding the most common pitfalls in the evaluation of the duodenum. • Cross-sectional imaging modalities enable comprehensive assessment of duodenum diseases. • Causes of duodenal obstruction include intraluminal masses, inflammation and hematomas. • Distinguishing between tumour and groove pancreatitis can be challenging by cross-sectional imaging. • Infectious diseases of the duodenum are difficult to diagnose, as the findings are not specific. • The most common cause of nonvariceal upper gastrointestinal bleeding is peptic ulcer disease.

Diagnosis and management of upper gastrointestinal bleeding in children.

PubMed

Owensby, Susan; Taylor, Kellee; Wilkins, Thad

2015-01-01

Upper gastrointestinal bleeding is an uncommon but potentially serious, life-threatening condition in children. Rapid assessment, stabilization, and resuscitation should precede all diagnostic modalities in unstable children. The diagnostic approach includes history, examination, laboratory evaluation, endoscopic procedures, and imaging studies. The clinician needs to determine carefully whether any blood or possible blood reported by a child or adult represents true upper gastrointestinal bleeding because most children with true upper gastrointestinal bleeding require admission to a pediatric intensive care unit. After the diagnosis is established, the physician should start a proton pump inhibitor or histamine 2 receptor antagonist in children with upper gastrointestinal bleeding. Consideration should also be given to the initiation of vasoactive drugs in all children in whom variceal bleeding is suspected. An endoscopy should be performed once the child is hemodynamically stable. © Copyright 2015 by the American Board of Family Medicine.

The predictive scale for mortality risk in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) proposed by Italy's PNED (Progetto Nazionale Emorragia Digestiva) group has not been validated in Latin America since its original publication. To compare the PNED system and the Rockall score as mortality predictors in patients hospitalized for NVUGIB. A multicenter, prospective, cross-sectional, analytic study was conducted that recruited patients diagnosed with nonvariceal upper gastrointestinal bleeding within the time frame of 2011 to 2015. Six Mexican hospital centers participated in the study. The Rockall and PNED system scores were calculated, classifying the patients as having mild, moderate, or severe disease. The association between mortality and risk was determined through the chi-square test and relative risk (RR) calculation. Statistical significance was set at a P<.05. Information on 198 patients was collected. Only 8 patients (4%) died from causes directly associated with bleeding. According to the Rockall score, 46 patients had severe disease (23.2%), 5 of whom died, with a RR of 5.5 (CI 1.35-22.02, P=.006). In relation to the PNED, only 8 patients had severe disease (4%), 5 of whom died, with a RR of 38.7 (CI 11.4-137.3, P=.001). The PNED system was more selective for classifying a case as severe, but it had a greater predictive capacity for mortality, compared with the Rockall score.

Gastrointestinal stromal tumors are the most common mesenchymal tumors of the gastrointestinal tract and occur rarely in the duodenum. Splenic angiosarcoma is an aggressive neoplasm with an extremely poor prognosis. We report a case of a 70-year-old man hospitalized for abdominal pain in the upper quadrants, dyspepsia and nausea, previously treated for Hodgkin lymphoma 30 years ago. Abdominal CT showed a solid nodular lesion in the third portion of the duodenum, the presence of retropancreatic, aortic and caval lymph nodes, and four nodular splenic masses. (111)In-octreotide scintigraphy revealed pathological tissue accumulation in the duodenal region, and in the retropancreatic, retroduodenal, aortic and caval lymph nodes, suggesting a nonfunctioning neuroendocrine peripancreatic tumor. At exploratory laparotomy, an exophytic soft tumor was found originating from the third portion of the duodenum. Pancreas-preserving duodenectomy with duodenojejunostomy, splenectomy and lymphnodectomy of retropancreatic aortic and caval lymph nodes were performed. Pathological evaluation and immunohistochemical studies showed the presence of a duodenal gastrointestinal stromal tumor with low mitotic activity and a well-differentiated angiosarcoma localized to the spleen and invading lymph nodes. We speculated that the angiosarcoma and duodenal gastrointestinal stromal tumors of this patient were due to the treatment of Hodgkin lymphoma with radiotherapy 30 years ago. Pancreas-preserving segmental duodenectomy can be used to treat non-malignant neoplasms of the duodenum and avoid extensive surgery. Splenectomy is the treatment of choice for localized angiosarcomas but a strict follow-up is mandatory because of the possibility of recurrence.

Rebleeding and mortality rates remain high in patients with nonvariceal upper gastrointestinal bleeding. To identify clinical and endoscopic risk factors for rebleeding and mortality in patients with nonvariceal upper gastrointestinal bleeding. This study was performed in patients with nonvariceal upper gastrointestinal bleeding who underwent upper endoscopic procedures between July 2006 and February 2013. Clinical and endoscopic characteristics were compared among patients with and without rebleeding and mortality. Logistic regression analysis was performed to determine independent risk factors for rebleeding and mortality. After excluding 64 patients, data for 689 patients with nonvariceal upper gastrointestinal bleeding were analyzed. Peptic ulcer (62.6 %) was by far the most common source of bleeding. Endoscopic intervention was performed within 24 h in 99.0 % of patients, and successful endoscopic hemostasis was possible in 80.7 % of patients. The 30-day rebleeding rate was 13.1 % (n = 93). Unsuccessful endoscopic hemostasis was found to be the only independent risk factor for rebleeding (odds ratio 79.6; 95 % confidence interval 37.8-167.6; p = 0.000). The overall 30-day mortality rate was 3.2 % (n = 23). Unsuccessful endoscopic hemostasis (odds ratio 4.9; 95 % confidence interval 1.7-13.9; p = 0.003) was also associated with increased 30-day mortality in patients with nonvariceal upper gastrointestinal bleeding. Successful endoscopic hemostasis is an independent protective factor for both rebleeding and mortality in patients with nonvariceal upper gastrointestinal bleeding.

AIM: To assess the practically usefulness and diagnostic yield of this new method in a group of patients with suspected small bowel lesions. METHODS: Capsule endoscopic (CE) examination by using M2A capsule endoscope TM (Given Imaging, Yoqneam, Israel) was performed in thirty nine patients (26 males, 13 females) with suspected small intestinal lesions. The composing of the patients was as follows: obscure gastrointestinal bleeding in twenty three patients, known Crohn’s disease in 6 patients, in whom CE was used to evaluate the severity and extension of the diseases, chronic diarrhea in 8 patients, abdominal pain in one patient and malignancy in one patient with unknown origin. RESULTS: In two patients CE failed. Different abnormalities were revealed in 26 patients overall. Detection rate of abnormalities was highest among patients with obscure gastrointestinal bleeding and the source of bleeding was demonstrated in 17 of 23 patients with obscure bleeding (73.9%). Entero-Behcet was diagnosed in two patients by CE as a source of obscure gastrointestinal bleeding. In 6 patients with known Crohn's disease, CE revealed better evaluation of the disease extension. In 3 of 8 (37.5%) patients with chronic diarrhea; CE revealed some mucosal abnormalities as the cause of chronic diarrhea. In a patient with unexplained abdominal pain and in a cancer patient with unknown origin, CE examination was normal. CONCLUSION: In our relatively small series, we found that capsule endoscopy is a useful diagnostic tool particularly in diagnosis of obscure gastrointestinal bleeding, chronic diarrhea and in estimating the extension of Crohn’s disease.

Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies. To characterize patients with nonvariceal upper gastrointestinal bleeding related to antithrombotics and their management, and to determine clinical predictors of adverse outcomes. Retrospective cohort of adults who underwent upper gastrointestinal endoscopy after nonvariceal upper gastrointestinal bleeding from 2010 to 2012. The outcomes were compared between patients exposed and not exposed to antithrombotics. Five hundred and forty-eight patients with nonvariceal upper gastrointestinal bleeding (67% men; mean age 66.5 ± 16.4 years) were included, of which 43% received antithrombotics. Most patients had comorbidities. Peptic ulcer was the main diagnosis and endoscopic therapy was performed in 46% of cases. The 30-day mortality rate was 7.7% (n = 42), and 36% were bleeding-related. The recurrence rate was 9% and 14% of patients with initial endoscopic treatment needed endoscopic retreatment. There were no significant differences between the exposed and non-exposed groups in most outcomes. Co-morbidities, hemodynamic instability, high Rockall score, low hemoglobin (7.76 ± 2.72 g/dL) and higher international normalized ratio (1.63 ± 1.13) were associated significantly with mortality in a univariate analysis. Adverse outcomes were not associated with antithrombotic use. The management of nonvariceal upper gastrointestinal bleeding constitutes a challenge to clinical performance optimization and clinical cooperation.

AIM: To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). METHODS: This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. RESULTS: A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. CONCLUSION: Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

2012-01-01

Intensivists are regularly confronted with the question of gastrointestinal bleeding. To date, the latest international recommendations regarding prevention and treatment for gastrointestinal bleeding lack a specific approach to the critically ill patients. We present recommendations for management by the intensivist of gastrointestinal bleeding in adults and children, developed with the GRADE system by an experts group of the French-Language Society of Intensive Care (Société de Réanimation de Langue Française (SRLF), with the participation of the French Language Group of Paediatric Intensive Care and Emergencies (GFRUP), the French Society of Emergency Medicine (SFMU), the French Society of Gastroenterology (SNFGE), and the French Society of Digestive Endoscopy (SFED). The recommendations cover five fields of application: management of gastrointestinal bleeding before endoscopic diagnosis, treatment of upper gastrointestinal bleeding unrelated to portal hypertension, treatment of upper gastrointestinal bleeding related to portal hypertension, management of presumed lower gastrointestinal bleeding, and prevention of upper gastrointestinal bleeding in intensive care.

Gastrointestinal stromal tumors (GISTs) are rare malignancies but the most common mesenchymal tumors of the digestive tract. Recent advances in diagnostic imaging and an increasing incidence will confront us more frequently with stromal tumors. This single center study aimed to characterize GIST patients in terms of tumor location, clinical presentation, metastasis formation, as well as associated secondary malignancies. In a retrospective study, 104 patients with a histologically confirmed diagnosis of GIST, collected between 1993 and 2011, were characterized for several clinical features. The most common GIST location was the stomach (67.6%) followed by the small intestine (16.2%). Gastrointestinal bleeding (55.8%) and abdominal pain (38.5%) were the most frequently reported symptoms whereas about one-third of patients remained clinically asymptomatic (31.6%); 14.4% of patients had either synchronous or metachronous metastases and there was a significant prevalence also in the low risk group. The proportion of secondary malignant associated neoplasms was 31% in our GIST cohort, among which gastrointestinal, genitourinary tumors, and breast cancer were the most prevalent. There was a considerable risk for metastasis formation and the development of secondary neoplasias that should encourage discussion about the appropriate surveillance strategy after surgery for GIST. © 2018 S.

Malignant glioma is the most common primary malignant brain tumor that displays high vascularity, making vascular endothelial growth factor receptors become promising targets. This study was conducted to evaluate the efficacy and safety of apatinib, a new potent oral small-molecule tyrosine kinase inhibitor targeted vascular endothelial growth factor receptor 2, combined with irinotecan, in patients with recurrent malignant glioma. Ten patients with recurrent malignant glioma who were experiencing relapse after treatment of temozolomide were enrolled in this study. They received oral apatinib (500 mg qd) in conjunction with irinotecan (340 mg/m or 125 mg/m depending on use of enzyme-inducing antiepileptic drugs) for 6 cycles. After that the patients continued to take apatinib as maintenance. Dosage adjustment occurred in only 3 (30.0%) patients. Among the 10 patients, 9 were available for the efficacy evaluation. There were 5 with partial response, 2 with stable disease and 2 with progressive disease. The objective response rate and the disease control rate (DCR) were 55% (5/9) and 78% (7/9), respectively. The median progress free survival time was 8.3 months. As for safety analysis, the most 3 common adverse events were gastrointestinal reaction (31.8%), hypertension (22.7%), and myelosuppression (18.0%). Apatinib combined with irinotecan seems to be a promising therapeutic option for recurrent malignant glioma patients. Perspective clinical studies with adequate sample size are required to validate our results. NCT02848794 /Ahead-BG306.

Esophageal cancer ranks among the most aggressive malignant diseases. The limited improvements in treatment outcomes provided by conventional therapies have prompted us to seek innovative strategies for treating this cancer. More than 100 trillion microorganisms inhabit the human intestinal tract and play a crucial role in health and disease conditions, including cancer. The human intestinal microbiome is thought to influence tumor development and progression in the gastrointestinal tract by various mechanisms. For example, Fusobacterium nucleatum , which primarily inhabits the oral cavity and causes periodontal disease, might contribute to aggressive tumor behavior through activation of chemokines such as CCL20 in esophageal cancer tissue. Composition of the intestinal microbiota is influenced by diet, lifestyle, antibiotics, and pro- and prebiotics. Therefore, by better understanding how the bacterial microbiota contributes to esophageal carcinogenesis, we might develop novel cancer prevention and treatment strategies through targeting the gastrointestinal microflora. This review discusses the current knowledge, available data and information on the relationship of microbiota with esophagitis, Barrett's esophagus, esophageal adenocarcinoma and squamous cell carcinoma.

Chlamydia muridarum with Mutations in Chromosomal Genes tc0237 and/or tc0668 Is Deficient in Colonizing the Mouse Gastrointestinal Tract

ABSTRACT Chlamydiae colonize the gastrointestinal tracts of both animals and humans. However, their medical significance remains unknown. We have previously shown that wild-type Chlamydia muridarum spreads to and establishes stable colonization of the gastrointestinal tract following intravaginal inoculation. In the present study, we found that C. muridarum with mutations in chromosomal genes tc0237 and/or tc0668 was defective in spreading to the mouse gastrointestinal tract, which correlated with its attenuated pathogenicity in the upper genital tract. This correlation was more consistent than that of chlamydial pathogenicity with ascending infection in the genital tract, since attenuated C. muridarum spread significantly less to the gastrointestinal tract but maintained robust ascending infection of the upper genital tract. Transcervical inoculation further confirmed the correlation between C. muridarum spreading to the gastrointestinal tract and its pathogenicity in the upper genital tract. Finally, defective spreading of C. muridarum mutants was due to their inability to colonize the gastrointestinal tract since intragastric inoculation did not rescue the mutants' colonization. Thus, promoting C. muridarum colonization of the gastrointestinal tract may represent a primary function of the TC0237 and TC0668 proteins. Correlation of chlamydial colonization of the gastrointestinal tract with chlamydial pathogenicity in the upper genital tract suggests a potential role for gastrointestinal chlamydiae in genital tract pathogenicity.

2017-09-01

Exclusive enteral nutrition is effective in pediatric Crohn disease but challenging as maintenance therapy. There is interest in food-based therapies such as the specific carbohydrate diet (SCD) but paucity of data on efficacy and effect on mucosal healing, an evolving target of IBD therapy. We conducted a retrospective review of the mucosal healing effect of the SCD in pediatric Crohn disease (CD). The endoscopic findings for children younger than 18 years with CD treated exclusively with the SCD or modified SCD (mSCD; SCD + addition of "illegal foods") were reviewed before and after the diet. Ileocolonoscopic examinations were scored according to the Simple Endoscopic Score for CD and findings on upper endoscopy were described. Seven subjects were identified, all on mSCD. The average age at starting the SCD was 11 ± 3.4 years and median duration of SCD/mSCD therapy was 26 months. All subjects reported no active symptoms before repeat endoscopic evaluation on mSCD, the majority had consistently normal C-reactive protein, albumin and hematocrit assessments, and mildly elevated fecal calprotectin (>50 μg/g, median 201, range 65-312) at any point within 3 months before the repeat endoscopy. One patient showed complete ileocolonic healing but persistent upper gastrointestinal tract ulceration. Complete macroscopic mucosal healing of both the ileocolon and upper gastrointestinal tract was not seen in any patient.

Upper gastrointestinal bleeding (UGIB) is a complication with a high mortality rate in critically ill patients presenting with cirrhosis. Today, there exist few accurate scoring models specifically designed for mortality risk assessment in critically ill cirrhotic patients with upper gastrointestinal bleeding (CICGIB). Our aim was to develop and evaluate a novel nomogram-based model specific for CICGIB. Overall, 540 consecutive CICGIB patients were enrolled. On the basis of Cox regression analyses, the nomogram was constructed to estimate the probability of 30-day, 90-day, 270-day, and 1-year survival. An upper gastrointestinal bleeding-chronic liver failure-sequential organ failure assessment (UGIB-CLIF-SOFA) score was derived from the nomogram. Performance assessment and internal validation of the model were performed using Harrell's concordance index (C-index), calibration plot, and bootstrap sample procedures. UGIB-CLIF-SOFA was also compared with other prognostic models, such as CLIF-SOFA and model for end-stage liver disease, using C-indices. Eight independent factors derived from Cox analysis (including bilirubin, creatinine, international normalized ratio, sodium, albumin, mean artery pressure, vasopressin used, and hematocrit decrease>10%) were assembled into the nomogram and the UGIB-CLIF-SOFA score. The calibration plots showed optimal agreement between nomogram prediction and actual observation. The C-index of the nomogram using bootstrap (0.729; 95% confidence interval: 0.689-0.766) was higher than that of the other models for predicting survival of CICGIB. We have developed and internally validated a novel nomogram and an easy-to-use scoring system that accurately predicts the mortality probability of CICGIB on the basis of eight easy-to-obtain parameters. External validation is now warranted in future clinical studies.

The purpose of this study was to determine the prevalence of upper gastrointestinal tract lesions in children with human immunodeficiency virus (HIV) infection who undergo endoscopy of the upper gastrointestinal tract and to identify important clinical predictors of abnormal endoscopic results. All HIV-infected children who underwent endoscopy and were followed at Children's Hospital, Boston, from January 1985 to August 1994 were studied. The main outcome measure was endoscopic results, which were categorized into observational, histologic, and microbiologic findings. Potential predictors included height, weight, nutritional interventions, HIV disease stage, CD4 T-lymphocyte count, medications, active infections, and indications for endoscopy. Forty-three endoscopies in unique patients are reported. Most children had advanced HIV infection (67% acquired immunodeficiency syndrome, mean CD4 T-lymphocyte count z score = -2.71, weight z score = -2.04). An abnormal endoscopic finding was discovered in 93% of children and confirmed by histologic, microbiologic, or a combination of these studies in 72% of children. Thirty-five percent of children had an opportunistic pathogen identified endoscopically; 65% of these pathogens were previously undiagnosed. Observational findings often were poor indicators of histologic and microbiologic abnormalities. Independent predictors of abnormal histologic findings include younger age at endoscopy (odds ratio (OR) = 1.16 per year, 95% confidence interval (CI) (1.02, 1.33)) and guaiac-negative stools (OR = 16.7, 95% CI (1.92, 142.9)). Independent predictors of finding a pathogen at the time of endoscopy include a greater number of indications for endoscopy (OR = 2.6 per indication, 95% CI (1.3, 5.3)) and diagnosis of acquired immunodeficiency syndrome (OR = 16.4, 95% CI (1.3, 213)). No other gastrointestinal, nutritional, or immunologic parameters were significantly predictive of endoscopic outcomes. Medical management was changed in 70% of children because of the endoscopic findings. Endoscopy is a useful tool to direct therapy against peptic and infectious disorders of the upper gastrointestinal tract in children with HIV infection. Specific gastrointestinal symptoms are not useful predictors of abnormal results.

A growing body of evidence in the international literature suggests that the prevalence of psychiatric morbidity including suicide is high among physicians. In addition, data published by Hungarian researchers in the early 1990-ies showed high prevalence of somatic morbidity in this population. Based on these data, it is hypothesised that the prevalence of psychiatric and somatic morbidity is higher among physicians in Hungary compared to the white collar population. To assess the psychiatric and somatic health status of physicians as well as the prevalence of role conflict among female physicians in Hungary using a representative sample. Data for this epidemiological study were collected from 407 physicians using questionnaires. 1752 white collar female and male workers from a representative survey (Hungarostudy 2002) served as controls. It is found that the prevalence of chronic somatic morbidity among both female and male physicians was significantly higher than that in the respective control groups. The prevalence of malignancies, diabetes, renal impairment, hypertension, myocardial infarction and cardiovascular diseases, and gastrointestinal ulcers was higher among male physicians compared to control. Female physicians exhibited higher prevalence of malignant diseases, hypertension, myocardial infarction, bronchial asthma, other pulmonary and cardiovascular diseases, allergies, gastrointestinal diseases including ulcer, ophthalmologic and gynaecological disorders compared with the normative population. This study is the first in Hungary to report a significantly higher prevalence of maternal reproductive morbidity including miscarriage, therapeutic termination of pregnancy, high-risk pregnancy among female physicians compared to women in the control group. Correlation analyses confirmed a significant relationship between high prevalence of morbidity and long working hours (> 8 hours), severe anxiety and stress, and role conflict.

Acute esophageal necrosis (AEN), also called “black esophagus,” is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. The patients are usually older and are critically ill with shared comorbidities, which include atherosclerotic cardiovascular disease, diabetes mellitus, hypertension, chronic renal insufficiency, and malnutrition. Alcoholism and substance abuse could be seen in younger patients. Patients usually have systemic hypotension along with upper abdominal pain in the background of clinical presentation of hematemesis and melena. The endoscopic findings confirm the diagnosis and biopsy is not always necessary unless clinically indicated in atypical presentations. Herein we present two cases with distinct clinical presentation and discuss the endoscopic findings along with a review of the published literature on the management of AEN. PMID:27642529

Intensive laboratory, preclinical and clinical studies have identified and validated molecular targets in cancers, leading to a shift toward the development of novel, rationally designed and specific therapeutic agents. However, gastrointestinal cancers continue to have a poor prognosis, largely due to drug resistance. Here, we discuss the current understanding of DNA synthesis inhibitors and their mechanisms of action for the treatment of gastrointestinal malignancies. Conventional agents, including DNA synthesis inhibitors such as fluoropyrimidines and platinum analogs, remain the most effective therapeutics and are the standards against which new drugs are compared. Novel DNA synthesis inhibitors for the treatment of gastrointestinal malignancies include a combination of the antimetabolite TAS-102, which consists of trifluorothymidine with a thymidine phosphorylase inhibitor, and a novel micellar formulation of cisplatin NC-6004 that uses a nanotechnology-based drug delivery system. The challenges of translational cancer research using DNA synthesis inhibitors include the identification of drugs that are specific to tumor cells to reduce toxicity and increase antitumor efficacy, biomarkers to predict pharmacological responses to chemotherapeutic drugs, identification of ways to overcome drug resistance and development of novel combination therapies with DNA synthesis inhibitors and other cancer therapies, such as targeted molecular therapeutics. Here, we discuss the current understanding of DNA synthesis inhibitors and their mechanisms of action for the treatment of gastrointestinal malignancies.

Necrotizing fasciitis is a devastating soft tissue infection affecting fascias and subcutaneous soft tissues. Literature reviews have identified several related risk factors, including malignancy, alcoholism, malnutrition, diabetes, male gender and old age. There are only scanty case reports in the literature describing its rare association with colorectal malignancy. All published cases are attributed to bowel perforation resulting in necrotizing fasciitis over the perineal region. Isolated upper or lower limb diseases are rarely identified. Simultaneous upper and lower limb infection in colorectal cancer patients has never been described in the literature. We report an unusual case of multi-limb necrotizing fasciitis in a patient with underlying non-perforated rectal carcinoma. PMID:16937546

Long non-coding RNAs (lncRNAs) are recently discovered RNA transcripts that are aberrantly expressed in many tumor types. Numerous studies have suggested that lncRNAs can be utilized for cancer diagnosis and prognosis. LSINCT5 (long stress-induced non-coding transcript 5) is dramatically upregulated in breast and ovarian cancer and affects cellular proliferation. However, the expression pattern of LSINCT5 in gastrointestinal cancer and the association between aberrant expression of LSINCT5 in gastrointestinal cancer and malignancy, metastasis, or prognosis remain unknown. LSINCT5 expression was detected in gastrointestinal cancer and paired adjacent normal tissue samples or cell lines using reverse transcription quantitative PCR (RT-qPCR). We also investigated the potential relationship between tumor LSINCT5 levels and clinicopathological features of gastrointestinal cancer. Finally, we assessed whether LSINCT5 influences in vitro cell proliferation. The expression of LSINCT5 is significantly upregulated in gastrointestinal cancer tissues and cell lines relative to their normal counterparts. In addition, increased LSINCT5 expression was correlated with a larger tumor size, deeper tumor depth, and advanced clinical stage. Kaplan-Meier analysis indicated that gastric cancer (GC) and colorectal cancer (CRC) patients with higher LSINCT5 expression levels have worse disease-free survival (DFS) and disease-specific survival (DSS) rates. Moreover, multivariate analysis revealed that increased expression of LSINCT5 is an independent predictor of DFS and DSS rates in GC patients. The ectopic expression of LSINCT5 in gastrointestinal cancer cell lines resulted in an increase in cellular proliferation; conversely, knock down of LSINCT5 significantly inhibited proliferation. These results suggest that LSINCT5 may represent a novel prognostic indicator and a target for gene therapy in gastrointestinal cancer.

Acute lower gastrointestinal bleeding accounts for approximately 20% of all acute gastrointestinal hemorrhages, and they are the most common urgent cases in gastroenterology. The aim of this study was to determine the most common etiology, efficacy in diagnostics and therapy, and the outcome in patients with acute lower gastrointestinal bleeding. Data were collected from the medical records of 86 patients who had been hospitalized for acute lower gastrointestinal bleeding in 2009 at the Ward of Gastroenterology and Hepatology, Clinical Centre of Vojvodina. The average age of the patients was 70.4 years (ranging from 37 to 88), and the largest number of patients 41/86 (47.7%) were between the ages 71 and 80. Colon diverticulosis was the most common cause of bleeding, and it occurred in 21 patients from the study sample (24.4%), and the other causes were malignant tumors (12/86, i.e. 13.9%), polyps (10/86, i.e. 11.6%), anorectal diseases (7/86, i.e. 8.3%/0) and colitis (8/86, i.e. 9.3%). No diagnostic procedures were performed in 15 patients (17.4%) due to their poor medical condition and comorbidities. The total mortality rate was 6/86 (6.9%), and the largest number of deaths occurred (5/86 i.e. 5.8%) due to a multisystem organ failure and underlying diseases which were not associated with acute lower gastrointestinal bleeding. Uncontrolled bleeding was the cause of death in only 1 patient (1.2%). Acute lower gastrointestinal bleeding is most commonly found in the older population, whose age, comorbidities, and ongoing therapy have impact on bleeding lesions, diagnostic and therapeutic modalities and the outcomes of bleeding. Endoscopic procedures are still the gold standard in diagnostics.

Lower deep venous thrombosis (DVT) is one of the major complications of patients with tumors or patients undergoing major surgery. Electrical acupoint stimulation, an established technique of traditional Chinese medicine (TCM), can be well combined with Western medicine to reduce the incidence of postoperative DVT, especially in elderly patients. The objectives of this study were to assess the efficiency of electrical acupoint stimulation in the prevention of postsurgery DVT in elderly patients with gastrointestinal malignant tumors and to validate an effective and safe nursing approach that integrates TCM and Western medicine. A total of 120 patients (none aged <60 years) who underwent malignant gastrointestinal tumor surgery between July 2005 and May 2007 were randomly divided into 3 groups: routine nursing group (group C1), graduated compression stockings group (group C2), and electrical acupoint stimulation group (group T). Hemorheological parameters (blood viscosity, etc) were measured and compared before and after surgery. Compared with groups C1 and C2, group T showed a significant difference in blood viscosity and blood flow velocity (P < .05). However, there were no statistical differences among groups C1, C2, and T in other hemorheological parameters. By speeding up the blood flow in patients' lower limbs, electrical acupoint stimulation showed a great potential to prevent symptomless DVT in elderly patients after malignant gastrointestinal tumor surgery. Western medical care combined with TCM can reduce the occurrence of lower DVT in elderly patients suffering from gastrointestinal cancer. This approach may help nurses to plan effective care for elderly patients.

Angiosarcoma of the face is a vascular tumor with poor local control and short median survival despite standard treatment. Bevacizumab is a humanized monoclonal antibody to vascular endothelial growth factor (VEGF), which can inhibit tumor growth. It is synergistic with radiotherapy in gastrointestinal malignancies. Given the vascular nature of angiosarcoma and the need for better treatment of this disease, we investigated the concurrent use of bevacizumab with preoperative radiotherapy for head and neck angiosarcoma. Two patients diagnosed with angiosarcoma of the nose were treated preoperatively with bevacizumab (5-10 mg/kg) and concurrent radiotherapy (50 Gy), followed by resection of the tumor bed. Both patients had a complete pathologic response with no residual disease. Neither has developed recurrence, with follow-up of 8.5 months and 2.1 years. The neoadjuvant combination of bevacizumab and radiation therapy is promising and should be further studied in the setting of vascular malignancies.

Imatinib mesylate has become the treatment of choice for gastrointestinal stromal tumors (GISTs) and has made a revolutionary impact on survival rates. Bone marrow necrosis is a very rare adverse event in malignant GIST. Bone metastases are also rarely encountered in the setting of this disease. The authors report on a patient with malignant GIST who developed a bone lesion, mimicking spinal metastasis on both MR imaging and FDG-PET/CT. Corpectomy and anterior fusion was performed, but the pathology report was consistent with bone marrow necrosis. Radiological and clinical similarities made the distinction between metastasis and bone marrow necrosis challenging for the treating physicians. Instead of radical surgical excision, more conservative methods such as percutaneous or endoscopic bone biopsies may be more useful for pathological confirmation, even though investigations such as MR imaging and FDG-PET/CT indicate metastatic disease.

Background Symptom-based surveys suggest that the prevalence of gastrointestinal diseases is lower in China than in Western countries. The aim of this study was to validate a methodology for the epidemiological investigation of gastrointestinal symptoms and endoscopic findings in China. Methods A randomized, stratified, multi-stage sampling methodology was used to select 18 000 adults aged 18-80 years from Shanghai, Beijing, Xi'an, Wuhan and Guangzhou. Participants from Shanghai were invited to provide blood samples and undergo upper gastrointestinal endoscopy. All participants completed Chinese versions of the Reflux Disease Questionnaire (RDQ) and the modified Rome II questionnaire; 20% were also invited to complete the 36-item Short Form Health Survey (SF-36) and Epworth Sleepiness Scale (ESS). The psychometric properties of the questionnaires were evaluated statistically. Results The study was completed by 16 091 individuals (response rate: 89.4%), with 3219 (89.4% of those invited) completing the SF-36 and ESS. All 3153 participants in Shanghai provided blood samples and 1030 (32.7%) underwent endoscopy. Cronbach's alpha coefficients were 0.89, 0.89, 0.80 and 0.91, respectively, for the RDQ, modified Rome II questionnaire, ESS and SF-36, supporting internal consistency. Factor analysis supported construct validity of all questionnaire dimensions except SF-36 psychosocial dimensions. Conclusion This population-based study has great potential to characterize the relationship between gastrointestinal symptoms and endoscopic findings in China. PMID:19925662

One of the promising methods for early diagnosis of malignant diseases of the respiratory organs and the gastrointestinal tract (GIT) is now considered a fluorescence method. Application autofluorescence phenomenon in endoscopy allows to obtain a fluorescent image of the mucosa, which shows the difference in the intensity of the autofluorescence of healthy and the affected tissue in the green and red regions of the spectrum. The result of the work is to determine on the basis of scientific research and prototyping capabilities of creating fluorescence video endoscope and the development of fluorescent light (illuminator FLU) for videoendoscopy complex. The solution of this problem is based on the method of studying biological objects in lifetime condition.

The value of using heparin as a pharmacologic intervention to induce a positive scintiscan was studied in a patient with chronic occult gastrointestinal bleeding. When all standard diagnostic tests (upper and lower gastrointestinal series, upper and lower endoscopy, and conventional noninterventional Tc-99m RBC imaging) fail to detect and localize gastrointestinal bleeding in a patient who has definite clinical evidence (guaiac positive stool and dropping hemoglobin, hematocrit) of chronic occult gastrointestinal oozing, heparin may be used (with proper precaution) as a last resort to aid in the scintigraphic detection and localization of chronic occult gastrointestinal bleeding.

A perivascular epithelioid cell neoplasm (PEComa) in the chest is rare, let alone in the mediastinum and lung. A 63-year-old man was admitted to our hospital with chest pain for more than 2 months and was found to have an opacity in his mediastinum and lung for 3 weeks. Enhanced chest computed tomography (CT) revealed a mass in both the left upper lobe and central anterior mediastinum. To identify the disease, a CT-guided percutaneous transthoracic needle biopsy of the upper left lung lesions was performed. The pathology result was consistent with epithelioid angiomyolipoma/PEComa. After a standard preparation for surgery, the neoplasms in the mediastinum and left lung were resected. The operative findings revealed extensive mediastinal tumor invasion in parts adjacent to the pericardium, including the mediastinal pleura, left pulmonary artery and vein, and phrenic nerve. The left lung tumor had invaded the lung membranes. The final pathologic diagnosis was malignant epithelioid angioleiomyoma in the left upper lung and mediastinum. Later, the mediastinal tumor recurred. The radiography of this case resembles left upper lobe lung cancer with mediastinal lymph node metastasis. Because this tumor lacks fat, the enhanced CT indicated that it was malignant but failed to identify it as a perivascular epithelioid cell neoplasm.This case reminds clinicians that, although most PEComa are benign, some can be malignant. As the radiology indicated, chest PEComas lack fat, which makes their preoperative diagnosis difficult. Therefore, needle biopsy is valuable for a definitive diagnosis.

Raman spectroscopy is an optical vibrational technology capable of probing biomolecular changes of tissue associated with cancer transformation. This study aimed to characterize in vivo Raman spectroscopic properties of tissues belonging to different anatomical regions in the upper gastrointestinal (GI) tract and explore the implications for early detection of neoplastic lesions during clinical gastroscopy. A novel fiber-optic Raman endoscopy technique was utilized for real-time in vivo tissue Raman measurements of normal esophageal (distal, middle, and proximal), gastric (antrum, body, and cardia) as well as cancerous esophagous and gastric tissues from 107 patients who underwent endoscopic examinations. The non-negativity-constrained least squares minimization coupled with a reference database of Raman active biochemicals (i.e., actin, histones, collagen, DNA, and triolein) was employed for semiquantitative biomolecular modeling of tissue constituents in the upper GI. A total of 1189 in vivo Raman spectra were acquired from different locations in the upper GI. The Raman spectra among the distal, middle, and proximal sites of the esophagus showed no significant interanatomical variability. The interanatomical variability of Raman spectra among normal gastric tissue (antrum, body, and cardia) was subtle compared to cancerous tissue transformation, whereas biomolecular modeling revealed significant differences between the two organs, particularly in the gastroesophageal junction associated with proteins, DNA, and lipids. Cancerous tissues can be identified across interanatomical regions with accuracies of 89.3% [sensitivity of 92.6% (162/175) specificity of 88.6% (665/751)], and of 94.7% [sensitivity of 90.9% (30/33) specificity of 93.9% (216/230)] in the gastric and esophagus, respectively, using partial least squares-discriminant analysis together with the leave-one tissue site-out, cross validation. This work demonstrates that Raman endoscopy technique has promising clinical potential for real-time, in vivo diagnosis and detection of malignancies in the upper GI at the molecular level.

Video assisted thoracoscopic and open chest surgery in diagnosis and treatment of malignant pleural diseases

PubMed Central

Waller, David A.

2017-01-01

Parenchymal cancers of lung, breast, gastrointestinal tract and ovaries as well as lymphomas and mesotheliomas are among the most common cancer types causing malignant effusions, though almost all tumour types have been reported to cause a malignant effusion. The prognosis heavily depends on patients’ response to systemic therapy however, regardless of the causing pathology and histopathologic form, malignant pleural disease is normally associated with a poor prognosis. To date, there are not sufficient data to allow accurate predictions of survival that would facilitate decision making for managing patients with malignant pleural diseases. Interventions are directed towards drainage of the effusion and, when appropriate, concurrent or subsequent pleurodesis or establishing long-term drainage to prevent re-accumulation. The rate of re-accumulation of the pleural effusion, the patient's prognosis, and the severity of the patient’s symptoms should guide the subsequent choice of therapy. In contemporary medicine, not many cancers have managed to generate as intense debates concerning treatment, as malignant pleural mesothelioma. The relative advantages of surgery, radiation, chemotherapy and any combination of the three are continuously reassessed and reconsidered, even though not always based on scientific evidence. The aim of surgery in mesothelioma may be prolongation of life, in addition to palliation of symptoms. Longer recovery periods from more extensive surgical procedures could be justified, in carefully selected patients. Surgical options include: Video assisted thoracoscopic (VATS) pleurodesis, VATS partial pleurectomy (VATS PP)—both parietal and visceral; open pleurectomy decortication (PD)—with an extended option (EPD) and extrapleural pneumonectomy (EPP). Current evidence implies that EPD can be performed reliably in specialised centres with good results, both in terms of mortality and survival; however, no operation has yet been shown to be beneficial in a prospective randomized controlled clinical trial.

Upper gastrointestinal bleeding is a major cause of hospitalization and the most prevalent emergency worldwide, with a mortality rate of up to 14%. In Peru, there have not been any studies on the use of the Glasgow-Blatchford Scoring System to predict mortality in upper gastrointestinal bleeding. The aim of this study is to perform an external validation of the Glasgow-Blatchford Scoring System and to establish the best cutoff for predicting mortality in upper gastrointestinal bleeding in a hospital of Lima, Peru. This was a longitudinal, retrospective, analytical validation study, with data from patients with a clinical and endoscopic diagnosis of upper gastrointestinal bleeding treated at the Gastrointestinal Hemorrhage Unit of the Hospital Nacional Edgardo Rebagliati Martins between June 2012 and December 2013. We calculated the area under the curve for the receiver operating characteristic of the Glasgow-Blatchford Scoring System to predict mortality with a 95% confidence interval. A total of 339 records were analyzed. 57.5% were male and the mean age (standard deviation) was 67.0 (15.7) years. The median of the Glasgow-Blatchford Scoring System obtained in the population was 12. The ROC analysis for death gave an area under the curve of 0.59 (95% CI 0.5-0.7). Stratifying by type of upper gastrointestinal bleeding resulted in an area under the curve of 0.66 (95% CI 0.53-0.78) for non-variceal type. In this population, the Glasgow-Blatchford Scoring System has no diagnostic validity for predicting mortality.

While ovarian mature cystic teratomas are benign ovarian germ-cell tumors and the most common type of all ovarian tumors, the formation of fistulas into surrounding organs such as the bladder and the intestinal tract is extremely rare. This report documents a case of ovarian mature cystic teratoma with a rectal fistula, thought to be caused by local inflammation. A pelvic mass was diagnosed as an ovarian mature cystic teratoma of approximately 10 cm in diameter on transvaginal ultrasound and magnetic resonance examinations. Endoscopic examination of the lower gastrointestinal tract to investigate diarrhea revealed an ulcerative lesion with hair in the rectal wall adjacent to the ovarian cyst, and formation of a fistula from the ovarian teratoma into the rectum was suspected. Laparotomy revealed extensive inflammatory adhesions between a left ovarian tumor and the rectum. Left salpingo-oophorectomy and upper anterior resection of the rectum were performed. The final pathological diagnosis was ovarian mature cystic teratoma with no malignant findings, together with severe rectal inflammation and fistula formation with no structural disorders such as diverticulitis of the colon or malignant signs. The formation of fistulas and invasion into the neighboring organs are extremely rare complications for ovarian mature cystic teratomas. The invasion of malignant cells into neighboring organs due to malignant transformation of the tumor is reported as the cause of fistula formation into the neighboring organs. A review of 17 cases including the present case revealed that fistula formation due to malignant transformation comprised only 4 cases (23.5 %), with inflammation as the actual cause in the majority of cases (13 cases, 76.5 %). Although malignancy is the first consideration when fistula formation is observed between ovarian tumors and surrounding organs, in mature cystic teratoma, local inflammation is more likely than malignant transformation.

OBJECTIVE: The authors report on indications and results of local excision of tumors of the ampulla of Vater. SUMMARY BACKGROUND DATA: Local excision of ampullary tumors has been performed for nearly a century but remains controversial. The use of this procedure for benign conditions is clear, but its place, if any, in the management of ampullary malignancy is debated. METHODS: The presentation, evaluation, and treatment of 26 patients who underwent local resection of ampullary tumors between January 1987 and November 1994 are reviewed. RESULTS: There were 16 men and 10 women, with a median age of 58 years. Eighteen patients had adenomas, whereas 8 patients had adenocarcinomas. Patients presented predominantly with jaundice (50%), pain (35%), and pancreatitis (27%) and were evaluated with endoscopic retrograde cholangiopancreatography and biopsy. All patients with benign lesions had accurate preoperative biopsies. Two of eight patients shown intraoperatively to have malignant lesions had preoperative biopsies read as benign. There were no deaths. Postoperative complications included two wound infections and one episode each of cholangitis, lower gastrointestinal bleeding, and adhesive gastrointestinal obstruction. All patients had prompt resolution of jaundice if present before surgery, and the mean postoperative stay was 7.5 days. Six of eight patients with malignant lesions have had recurrent disease. CONCLUSIONS: Local excision of malignant ampullary tumors is effective palliative therapy when the patient is unfit for the Whipple procedure. Ampullary resection usually is curative for patients with benign lesions without a polyposis syndrome. In this series, intraoperative frozen section routinely was accurate. Images Figure 4.

In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning. To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis. A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non-surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease. A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13-2.10)) whereas age >/=40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70-0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21-0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32-7.89)). A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North-South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres.

Postoperative, iatrogenic or spontaneous upper gastrointestinal defects result in significant morbidity and mortality of the patients. In the last few years, endoscopic vacuum therapy (EVT) has been recognized as a new promising method for repairing upper gastrointestinal defects of different etiology. However, probably due to insufficient data and no commercially available system for EVT of the upper gastrointestinal tract, until the end of 2014, covering of esophageal defects with self-expanding metal stents (SEMS) were still the mainstay of endoscopic therapy. The aim of this article is to review the data available about EVT for various upper gastrointestinal defects. A selective literature search was conducted in Medline and PubMed (2007-2016), taking into account all the published case series and case reports reporting on the use of EVT in the management of upper gastrointestinal defects. EVT works through intracorporal application of negative pressure at the defect zone with an electronic controlled vacuum device along a polyurethane sponge drainage. This results in closure of the esophageal defect and internal drainage of the septic focus, simultaneously. Compared to stenting, EVT enables regular viewing of wound conditions with control of the septic focus and adjustment of therapy. Moreover, endoscopical negative pressure is applicable in all esophageal regions (cricopharygeal, tubular, gastroesophageal junction) and in anastomotic anatomic variants. EVT can be used solely as a definite treatment or as a complimentary therapy combined with operative revision. In total, there are published data of more than 200 patients with upper gastrointestinal defects treated with EVT, showing succes rates from 70-100%. The available data indicate that EVT is feasible, safe and effective with good short-term and long-term clinical outcomes in the damage control of upper GI-tract leaks. Still, a prospective multi-center study has to be conducted to proof the definite benefit of EVT for patients with esophageal defects.

Abstract Background: Malignant glioma is the most common primary malignant brain tumor that displays high vascularity, making vascular endothelial growth factor receptors become promising targets. This study was conducted to evaluate the efficacy and safety of apatinib, a new potent oral small-molecule tyrosine kinase inhibitor targeted vascular endothelial growth factor receptor 2, combined with irinotecan, in patients with recurrent malignant glioma. Methods: Ten patients with recurrent malignant glioma who were experiencing relapse after treatment of temozolomide were enrolled in this study. They received oral apatinib (500 mg qd) in conjunction with irinotecan (340 mg/m2 or 125 mg/m2 depending on use of enzyme-inducing antiepileptic drugs) for 6 cycles. After that the patients continued to take apatinib as maintenance. Dosage adjustment occurred in only 3 (30.0%) patients. Results: Among the 10 patients, 9 were available for the efficacy evaluation. There were 5 with partial response, 2 with stable disease and 2 with progressive disease. The objective response rate and the disease control rate (DCR) were 55% (5/9) and 78% (7/9), respectively. The median progress free survival time was 8.3 months. As for safety analysis, the most 3 common adverse events were gastrointestinal reaction (31.8%), hypertension (22.7%), and myelosuppression (18.0%). Conclusion: Apatinib combined with irinotecan seems to be a promising therapeutic option for recurrent malignant glioma patients. Perspective clinical studies with adequate sample size are required to validate our results. Trial Registration: NCT02848794 /Ahead–BG306. PMID:29245310

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. The most common computed tomographic appearance of heterotopic pancreas is that of a small oval intramural mass with microlobulated margins and an endoluminal growth pattern. The attenuation and enhancement characteristics of these lesions parallel their histologic composition. Acinus-dominant lesions demonstrate avid homogeneous enhancement after intravenous contrast material administration, whereas duct-dominant lesions are hypovascular and heterogeneous. At magnetic resonance imaging, the heterotopic pancreas is isointense to the orthotopic pancreas, with characteristic T1 hyperintensity and early avid enhancement after intravenous gadolinium-based contrast material administration. Heterotopic pancreatic tissue has a rudimentary ductal system in which an orifice is sometimes visible at imaging as a central umbilication of the lesion. Complications of heterotopic pancreas include pancreatitis, pseudocyst formation, malignant degeneration, gastrointestinal bleeding, bowel obstruction, and intussusception. Certain complications may be erroneously diagnosed as malignancy. Paraduodenal pancreatitis is thought to be due to cystic degeneration of heterotopic pancreatic tissue in the medial wall of the duodenum. Recognizing the characteristic imaging features of heterotopic pancreas aids in differentiating it from cancer and thus in avoiding unnecessary surgery. © RSNA, 2017.

Stem cells in gastrointestinal cancers: The road less travelled

PubMed Central

Mikhail, Sameh; Zeidan, Amer

2014-01-01

Cancer stem cells (CSC) are thought to be malignant cells that have the capacity to initiate and maintain tumor growth and survival. Studies have described CSC in various gastrointestinal neoplasms such as colon, pancreas and liver and gastroesophageal tumors. The mechanism by which CSC develop remains unclear. Several studies have explored the role of dysregulation of the Wnt/β-catenin, transformation growth factor-beta and hedhog pathways in generation of CSC. In this review, we discuss the various molecular abnormalities that may be related to formation of CSC in gastrointestinal malignancies, strategies to identify CSC and therapeutic strategies that are based on these concepts. Identification and targeting CSC is an intriguing area and may provide a new therapeutic option for patients with cancer including gastrointestinal malignancies. Although great progress has been made, many issues need to be addressed. Precise targeting of CSC will require precise isolation and characterization of those cells. This field is also evolving but further research is needed to identify markers that are specific for CSC. Although the application of this field has not entered the clinic yet, there continues to be significant optimism about its potential utility in overcoming cancer resistance and curing patients with cancer.

Peritoneal surface malignancies (PSM) are a clinical entity with an unfavourable prognosis. They comprise peritoneal carcinomatosis, pseudomyxoma peritonei, and primitive tumors of the peritoneum. Because the treatment of PSM presents unique and challenging problems to the cancer clinician, many new approaches have been attempted in recent years. In the current and next issues of World Journal of Gastrointestinal Oncology, some international groups of researchers discuss the most important and innovative aspects of PSM treatment, with particular accuracy for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. In conclusion, because this new approach to PSM has a reputation for being based more on common sense than on experimental data, I hope that highlighting this topic can make a contribution to the treatment of this group of diseases.

To assess the prevalence of dental caries, periodontal diseases, oral pre-malignant and malignant lesions in relation to socioeconomic factors among the municipal employees of Mysore city. The study was cross sectional in nature. All the available employees (1187) during the study period were considered. World Health Organization (WHO) Oral Health Assessment form (1997) and a preformed questionnaire were used to collect the required data. Modified Kuppuswamy scale with readjustment of the per capita income to suit the present levels was used for classifying the individuals into different socioeconomic status (SES) categories. Data were collected by a single, trained and calibrated examiner (dentist) using mouth mirror and community periodontal index (CPI) probe under natural daylight. Data analysis was done using SPSS windows version 10. Quantitative data were analyzed using one-way analysis of variance (ANOVA) with Tukey's post hoc test and qualitative data were analyzed using chi-square or contingency coefficient. The age range of the study population was 19-57 years (mean 40.74 years, standard deviation 9.17). The prevalence of dental caries in the upper SES category was lesser (43.3%) compared to that in lower SES category (78.6%). 16.4% of the subjects in the upper category had a CPI score of 0 (healthy periodontium) and none of the subjects in the lower middle, upper lower and lower SES category had this score. The prevalence of oral pre-malignant and malignant lesions was higher in lower SES category (17.9%) than in upper class (0%). There was an inverse relationship between oral health status and SES. The overall treatment need was more in the lower class people than in the upper class.

[Nonsteroidal Anti-inflammatory Drug and Aspirin-induced Peptic Ulcer Disease].

PubMed

Shim, Young Kwang; Kim, Nayoung

Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

This observational, retrospective cohort study assessed outcomes of the current management strategies for nonvariceal upper gastrointestinal bleeding in several European countries (Belgium, Greece, Italy, Norway, Portugal, Spain, and Turkey) (NCT00797641; ENERGIB). Turkey contributed 23 sites to this study. Adult patients (≥18 years old) consecutively admitted to hospital and who underwent endoscopy for overt non-variceal upper gastrointestinal bleeding (hematemesis, melena or hematochezia, with other clinical/laboratory evidence of acute upper GI blood loss) were included in the study. Data were collected from patient medical records regarding bleeding continuation, re-bleeding, pharmacological treatment, surgery, and mortality during a 30-day follow-up period. A total of 423 patients (67.4% men; mean age: 57.8 ± 18.9 years) were enrolled in the Turkish study centers, of whom 96.2% were admitted to hospital with acute non-variceal upper gastrointestinal bleeding. At admission, the most common symptom was melena (76.1%); 28.6% of patients were taking aspirin, 19.9% were on non-steroidal anti-inflammatory drugs, and 7.3% were on proton pump inhibitors. The most common diagnoses were duodenal (45.2%) and gastric (27.7%) ulcers and gastritis/gastric erosions (26.2%). Patients were most often managed in general medical wards (45.4%). A gastrointestinal team was in charge of treatment in 64.8% of cases. Therapeutic procedures were performed in 32.4% of patients during endoscopy. After the endoscopy, most patients (94.6%) received proton pump inhibitors. Mean (SD) hospital stay was 5.36 ± 4.91 days. The cumulative proportions of continued bleeding/re-bleeding, complications and mortality within 30 days of the non-variceal upper gastrointestinal bleeding episode were 9.0%, 5.7% and 2.8%, respectively. In the Turkish sub-group of patients, the significant risk factors for bleeding continuation or re-bleeding were age >65 years, presentation with hematemesis or shock/syncope, and the diagnosis of duodenal ulcer. The risk of clinical complications after non-variceal upper gastrointestinal bleeding was higher in female patients older than 65 years, in patients with comorbidities, and in patients presenting with shock/syncope, and also according to time to endoscopy. The use of aspirin, non-steroidal anti-inflammatory drugs or warfarin at baseline was negatively associated with the development of bleeding or clinical complications. The risk of death within 30 days after non-variceal upper gastrointestinal bleeding was significantly higher in patients older than 65 years and in those receiving transfusions other than intravenous fluid or red blood cells within 12 hours of presentation. According to the survey results, non-variceal upper gastrointestinal bleeding in Turkey varies from that in other European countries in a number of aspects. These differences could be associated with a younger population and Helicobacter pylori incidence. Despite the diminishing need for surgical intervention and mortality rates for non-variceal upper gastrointestinal bleeding, as is the case in other European countries, non-variceal upper gastrointestinal bleeding remains a serious problem.

The incidence of Crohn's disease has been increasing in Western communities, but there are no published studies which have examined this change in children in Australia. The centralization of pediatric gastroenterology services in Victoria provides an opportunity to examine these changes within one state. We undertook a retrospective study over a 31-year period of all children aged 16 years or less initially diagnosed with Crohn's disease at either the Royal Children's Hospital, or Monash Medical Center, Melbourne, Victoria. We identified 351 patients who met the diagnostic criteria between 1971 and 2001. The incidence of Crohn's disease in children aged 16 years or less rose from 0.128 to 2.0 per 100,000 per year over the three decades (r = 0.964, P < 0.01). There was a disproportionate over-representation of children from an urban background (incidence rate ratio 1.66, 95% CI 1.28-2.16). Children currently being diagnosed had on average a lower erythrocyte sedimentation rate (ESR) and higher albumin than in previous decades. The use of flexible endoscopy has increased markedly (1970s: 60%; 1990s: 96%, P < 0.05) and the proportion of children recognized at diagnosis with upper gastrointestinal and colonic involvement has increased significantly. There has been a significant increase in the incidence of Crohn's disease in Victorian children. The pattern of disease has also changed with colonic disease now more frequent, and inflammatory indices less abnormal. The increased use of endoscopy has established the frequent involvement of the upper gastrointestinal tract.

Background and study aims: Gastrointestinal bleeding in children and adolescents accounts for up to 20 % of referrals to gastroenterologists. Detailed management guidelines exist for gastrointestinal bleeding in adults, but they do not encompass children and adolescents. The aim of this study was to assess gastrointestinal bleeding in pediatric patients and to determine an investigative management algorithm accounting for the specifics of children and adolescents. Patients and methods: Pediatric patients with gastrointestinal bleeding admitted to our endoscopy unit from 2001 to 2009 (n = 154) were identified. Retrospective statistical and neural network analysis was used to assess outcome and to determine an investigative management algorithm. Results: The source of bleeding could be identified in 81 % (n = 124/154). Gastrointestinal bleeding was predominantly lower gastrointestinal bleeding (66 %, n = 101); upper gastrointestinal bleeding was much less common (14 %, n = 21). Hematochezia was observed in 94 % of the patients with lower gastrointestinal bleeding (n = 95 of 101). Hematemesis (67 %, n = 14 of 21) and melena (48 %, n = 10 of 21) were associated with upper gastrointestinal bleeding. The sensitivity and specificity of a neural network to predict lower gastrointestinal bleeding were 98 % and 63.6 %, respectively and to predict upper gastrointestinal bleeding were 75 % and 96 % respectively. The sensitivity and specifity of hematochezia alone to predict lower gastrointestinal bleeding were 94.2 % and 85.7 %, respectively. The sensitivity and specificity for hematemesis and melena to predict upper gastrointestinal bleeding were 82.6 % and 94 %, respectively. We then developed an investigative management algorithm based on the presence of hematochezia and hematemesis or melena. Conclusions: Hematochezia should prompt colonoscopy and hematemesis or melena should prompt esophagogastroduodenoscopy. If no source of bleeding is found, additional procedures are often non-diagnostic. PMID:27652293

Amongst all cancer subtypes, gastrointestinal tumours are responsible for most cancer-related deaths. In most of the cases, the limitation of the prognosis of patients with malignant gastrointestinal tumours can be attributed to delayed diagnosis of the disease. In the last decade, secondary prevention strategies, in particular tumour screenings, have been identified to significantly improve the identification of patients with early-stage disease, leading to more effective therapeutic interventions. Therefore, new screening methods and further innovative treatment approaches may lead to an increase in progression-free and overall survival rates. Exosomes are small microvesicles with a size of 50-150 nm. They are formed in the endosomal system of many different cell types, where they are packed with nucleotides and proteins from the parental cell. After their release into the extracellular space, exosomes can deliver their cargo into recipient cells. By this mechanism, tumour cells can recruit and manipulate the adjacent and systemic microenvironment in order to support invasion and dissemination. Cancer-derived exosomes in the blood may provide detailed information about the tumour biology of each individual patient. Moreover, tumour-derived exosomes can be used as targetable factors and drug delivery agents in clinical practice. In this review, we summarise new aspects about novel implications in the diagnosis and treatment of gastrointestinal cancer and show how circulating exosomes have come into the spotlight of research as a high potential source of 'liquid biopsies'.

Metastases in the stomach are rare. The increased use of esophagogastroduodenoscopy (EGD), associated with better treatment results for malignancies, requires them to be acknowledged. The aim of this study was to describe a series of cases of metastasis to the stomach, their primary sites, clinical and endoscopic features, treatment, and results. Twenty cases were diagnosed between December 1999 and January 2004. Their analysis included symptomatology, macroscopic presentation, time from diagnosis of the primary tumor to the detection of the gastric metastasis, treatment approach, and survival. The primary sites were the esophagus, skin, lung, cervix, breast, sigmoid colon, and testis. The symptom most frequently requiring EGD was upper gastrointestinal bleeding. Ten patients showed concomitant metastases to other organs. The mean time between diagnosis of the primary tumor and diagnosis of gastric metastasis was 16 months (range, 0 to 56 months). Only seven patients were given some form of treatment after diagnosis of the gastric metastasis. The median survival was 4.75 months. Overall survival during the first year was 20% and survival was nil at 2 years. Gastric metastasis marks advanced disease and the prognosis is poor. New advances in diagnosis and treatment are required for better results.

A 73-year-old man was referred to our hospital for further examination of a depressed lesion in the stomach found by cancer screening gastroscopy. A barium upper gastrointestinal series showed an area of irregular mucosa measuring 15 mm on the anterior wall of the gastric body. Esophagogastroduodenoscopy revealed a 15 mm depressed lesion on the anterior wall of the lower gastric body. We suspected an undifferentiated adenocarcinoma from the appearance and took some biopsies. However, histology of the specimens revealed amyloidal deposits in the submucosal layer without malignant findings. Congo red staining was positive for amyloidal protein and green birefringence was observed under polarized light microscopy. Congo red staining with prior potassium permanganate incubation confirmed the light chain (AL) amyloid type. There were no amyloid deposits in the colon or duodenum. Computed tomography of the chest, abdomen, and pelvis showed no remarkable findings. Thus, this case was diagnosed as a localized gastric amyloidosis characterized by AL type amyloid deposition in the mucosal or submucosal layer. As the clinical outcome of gastric AL amyloidosis seems favorable, this case is scheduled for periodic examination to recognize potential disease progression and has been stable for 2 years.

Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding. A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery. Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.

Nonuremic calciphylaxis precipitated by teriparatide [rhPTH(1-34)] therapy in the setting of chronic warfarin and glucocorticoid treatment.

Calciphylaxis occurs rarely in the absence of end stage renal disease. Predisposing factors for nonuremic calciphylaxis (NUC) include hyperparathyroidism, coagulopathies, connective tissue disease, liver disease, glucocorticoid use, and malignancy. Warfarin can facilitate vascular calcification by reducing vitamin K-dependent carboxylation of matrix-Gla proteins. An 86-year-old Caucasian woman with a history of polymyalgia rheumatica, two spontaneous deep venous thromboses (DVTs) and multiple fractures was treated with calcium, vitamin D, prednisone, and warfarin. The patient's low bone density was treated initially with estrogen, then oral bisphosphonate, which was discontinued due to upper gastrointestinal symptoms. Nasal calcitonin was initiated. After 10 years of calcitonin treatment, she was changed to teriparatide. Two months after initiating teriparatide, she developed lower extremity edema and painful erythematous nodular lesions on her calves bilaterally, that progressed to necrotic ulcers despite antibiotic therapy. Biopsy of the lesions showed calcification in the media of small blood vessels and subcutaneous fat with fat necrosis, consistent with calciphylaxis. Teriparatide was discontinued. Aggressive wound care, antibiotics, and intravenous zoledronic acid were initiated. With cessation of teriparatide therapy and intensive wound care, the patient's lesions resolved over 8 months. We report the first case of NUC precipitated by teriparatide therapy. Our patient had multiple underlying predisposing factors including a connective tissue disorder, glucocorticoid therapy, warfarin use, and possible underlying coagulopathy given her history of multiple DVTs. In such patients, alternative osteoporosis therapies may be preferred.

Gastro-entero anastomosis with flexible endoscope with the help of rare-earth magnets on biosynthetic model made of the gastrointestinal tract of slaughtered pigs Numerous malignant diseases may cause gastric outlet obstruction. The surgical gastrointestinal bypass, besides the fact that it requires narcosis, is also associated with high risks for patients with poor general condition. Endoscopic insertion of self-expandable metal stent is less invasive, but often causes complications. In the last years some studies examined a new minimal invasive technique, in which magnets are used to create gastroenteric anastomosis. A biosynthetic model was developed from combined synthetic materials with biogenic specimens taken from slaughtered domestic pigs. The procedure was performed with endoscopic and fluoroscopic guidance. To increase X-ray contrast differences the model was put into physiological saline solution. Two rare-earth magnets (Br: 2500 Gauss, D: 10 mm) with central hole were inserted with the help of a guiding wire and duodenal probe. The first magnet was placed in the first jejunal loop; the second one was placed in the stomach. The gastric magnet was maneuvered using the endoscope. When the magnets reached the right position, the guiding wires were removed to let the magnets stick together. The pressure between the magnets will result in a sterile inflammation on the living tissue which develops adhesion between the bowels, and 7-10 days later anastomosis will develop as a result of the necrosis. The biosynthetic model could be used for training endoscopy without sacrificing animals. In the end of the procedure the magnets stuck together across gastric and jejunal walls in all ten cases successfully. By practice the period necessary for the procedure could be decreased from 40 to 20 minutes. The technique could be made with standard upper endoscope and instruments, and after practice on living animals it could potentially be a useful solution for complaints of gastric outlet obstruction.

Gastrointestinal symptoms are very frequent in myotonic dystrophy but largely unrecognized. They can be the revealing factors of the disease. We report 2 cases of 10 and 17-year-old children with persistent encopresis starting at the age of 3 and 5 years in spite of laxative treatment. Neurological examination and anorectal manometry provided the diagnosis of myotonic dystrophy. Procainamide treatment was introduced and the digestive symptoms improved. Any child with encopresis should have complete evaluation to rule out the diagnosis of myotonic dystrophy and physicians should look for upper and/or lower gastrointestinal symptoms in every patient with myotonic dystrophy.

Marked epidemiological changes in upper gastrointestinal diseases and Helicobacter pylori infection have taken place in the Asian Pacific region. In particular, differences with respect to race in the multiracial Asian population in Malaysia have been important and interesting. A time trend study of upper gastrointestinal disease and H. pylori infection in three time periods: 1989-1990, 1999-2000 and 2009-2010 spanning a period of 20 years was carried out. Consecutive first time gastroscopies carried out on patients attending the University of Malaya Medical Center were studied. Diagnoses and H. pylori infection status were carefully recorded. A steady decline in prevalence of duodenal ulcer (DU) and gastric ulcer (GU) from 21.1% to 9.5% to 5.0% and from 11.9% to 9.4% to 9.9% while an increase in erosive oesophagitis (EO) from 2.0% to 8.4% to 9.5% (chi-square for trend; P < 0.001) for the periods 1989-1990, 1999-200 and 2009-2010 were observed. The overall prevalence of H. pylori had also decreased from 51.7% to 30.3% to 11.1% for the same periods of time. The proportion of H. pylori positive ulcers had also decreased: DU (90.1%-69.8%-28.9%) and GU (86.6-56.8%-18.9%) (P < 0.001). This was observed in Malays, Chinese and Indians but the difference over time was most marked in Malays. There was a steady decline in the proportion of patients with gastric and oesophageal cancers. Peptic ulcers have declined significantly over a 20-year period together with a decline in H. pylori infection. In contrast, a steady increase in erosive oesophagitis was observed. Gastric and oesophageal squamous cell cancers have declined to low levels. © 2016 John Wiley & Sons Ltd.

Gall bladder carcinoma accounts for 98% of all the gall bladder malignancies and it is the sixth most common malignancy of the gastrointestinal tract worldwide. The incidence of incidental gall bladder carcinoma which is diagnosed during or after a laparoscopic cholecystectomy is reported to be around 0.19-3.3% in the literature. This study was aimed at detecting the incidence of gall bladder carcinomas which were diagnosed incidentally during or after laparoscopic cholecystectomies which were done for gall stone disease and cholecystitis. We analyzed the medical records of patients with symptomatic gallstone disease and acute or chronic cholecystitis, who underwent laparoscopic cholecystectomies at the Hakeem Abdul Hameed Centenary Hospital during the period from January 2007 to June 2012. A total of 622 laparoscopic cholecystectomies were performed at our institute during the study period of five and a half years. In 6 (0.96%) cases, incidental carcinomas of the gallbladder were discovered. A laparoscopic cholecystectomy which is performed for benign gall bladder disease rarely results in a diagnosis of unexpected gallbladder cancer. The microscopic examination of the specimens, with special attention to the depth of invasion, range of the mucosal spread and the lymphovascular involvement, is critical in diagnosing the incidental malignancies as well as for the subsequent management of the cases.

Helicobacter pylori (Hp) infection is mainly acquired during childhood; it is recognised as a cause of gastritis and peptic ulcer and it has been classified as a group A carcinogen by World Health Organization. The exact mode of transmission is as yet, not known. Aim of our study has been to identify risk factors associated with Helicobacter pylori infection in a preschool and school population and to confirm if Hp antigen in faeces is useful as screening in epidemiological studies. We interviewed, with questionnaire, 400 children (203 male; age range 3-10 years; mean age 6 years) of 3 different schools and stool samples were collected of all children too. 35 of 400 (8%) children underwent to upper gastrointestinal endoscopy because of a suspect of upper gastrointestinal disease. stool were collected from 400 school children and 35 of them shown positivity of Hp antigen test. A questionnaire about presence of nausea, vomit, recurrent abdominal pain, family size, parent's occupations and education, use of antibiotics, country of birth of child and parents, personal hygiene, breast feeding, presence of the animals was completed. 35 children with positive Hp stool antigen test and a suspicious of upper gastrointestinal disease (recurrent abdominal pain, diurnal or nocturnal abdominal pain, nausea, vomiting, iron deficiency) underwent to esophagogastroduodenoscopy (EGDS) that demonstrated antral gastritis and positive histology and urease rapid test. the results of this study suggest that risk factors for Hp infection are low socioeconomics factors, hygiene and living conditions and that Hp antigen in faeces is useful as screening test.

Patients with upper gastrointestinal bleeding (UGIB) require an early, tailored approach best guided by knowledge of the bleeding lesion, especially a variceal versus a nonvariceal source. To identify, by investigating a large national registry, variables that would be predictive of a variceal origin of UGIB using clinical parameters before endoscopic evaluation. A retrospective study was conducted in 21 Canadian hospitals during the period from January 2004 until the end of May 2005. Consecutive charts for hospitalized patients with a primary or secondary discharge diagnosis of UGIB were reviewed. Data regarding demographics, including historical, physical examination, initial laboratory investigations, endoscopic and pharmacological therapies administered, as well as clinical outcomes, were collected. Multivariable logistic regression modelling was performed to identify clinical predictors of a variceal source of bleeding. The patient population included 2020 patients (mean [± SD] age 66.3±16.4 years; 38.4% female). Overall, 215 (10.6%) were found to be bleeding from upper gastrointestinal varices. Among 26 patient characteristics, variables predicting a variceal source of bleeding included history of liver disease (OR 6.36 [95% CI 3.59 to 11.3]), excessive alcohol use (OR 2.28 [95% CI 1.37 to 3.77]), hematemesis (OR 2.65 [95% CI 1.61 to 4.36]), hematochezia (OR 3.02 [95% CI 1.46 to 6.22]) and stigmata of chronic liver disease (OR 2.49 [95% CI 1.46 to 4.25]). Patients treated with antithrombotic therapy were more likely to experience other causes of hemorrhage (OR 0.44 [95% CI 0.35 to 0.78]). Presenting historical and physical examination data, and initial laboratory tests carry significant predictive ability in discriminating variceal versus nonvariceal sources of bleeding.

Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the role of surgery in metastatic disease of the thyroid. Isolated thyroidectomy has been proposed as a local disease control option to palliate and prevent the potential morbidity of tumor extension related to the airway. Here, we present a case of a patient with breast cancer metastases to the thyroid gland and discuss the role of thyroidectomy in the context of the current literature. A 62-year-old Afro-Caribbean woman was diagnosed as having bilateral breast carcinoma in 2004, for which she underwent bilateral mastectomy. The pathology revealed multifocal disease on the right, T2N0(0/20)M0 grade 1 and 2 invasive ductal carcinoma, and on the left side, T3N1(2/18)M0 grade 1 invasive ductal carcinoma. Surgery was followed by adjuvant chemotherapy and regional radiotherapy. The disease was under control on hormonal therapy until 2016, when she developed cervical lymphadenopathy. The fine-needle aspiration cytology of the thyroid was reported as papillary thyroid cancer; and the fine-needle biopsy of the left lateral nodal disease was more suggestive of breast malignancy. She underwent a total thyroidectomy and a clearance of the central compartment lymph nodes and a biopsy of the lateral nodal disease. The histopathological analysis was consistent with metastatic breast cancer in the thyroid and lymph nodes with no evidence of a primary thyroid malignancy. A past history of a malignancy elsewhere should raise the index of suspicion of metastatic disease in patients presenting with thyroid lumps with or without cervical lymphadenopathy. Detection of metastases to the thyroid generally indicates poor prognosis, obviating the need of surgery in an already compromised patient. An empirical thyroidectomy should be considered in select patients for local disease control.

Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. From 133 patients (84 men) Rockall classification was possible in 126: 76 score ≥5, 50 score <5. One persistent bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall <5 patients started oral diet sooner than Rockall ≥5. Patients that underwent endoscopic therapy were refed earlier than those without endotherapy. Most feeding records are missing. Data reveals delayed refeeding, especially in patients with low-risk lesions who should have been fed immediately. Nonvariceal upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.

Gastroesophageal variceal hemorrhage is a lethal complication of portal hypertension. Liver cirrhosis is often the principal cause of the portal hypertensive state. Malignant tumors coexist with portal hypertension in some cases. Non-small-cell lung cancer (NSCLC) is likely to become metastatic. Liver is a frequent site of cancer metastasis, but diffuse hepatic sinusoidal metastasis is uncommon as a metastatic form of NSCLC. This report describes a patient with gastroesophageal variceal hemorrhage owing to a metastatic liver tumor of NSCLC. The patient, a male smoker with stage IV NSCLC, was free of any hepatitis viral infection and had no alcohol addiction. Liver dysfunction and liver disease had never been pointed out in his medical history. His tumor harbored an L858R epidermal growth factor receptor mutation. Gefitinib was initiated but had to be ceased because of interstitial lung disease. Sequential steroid therapy was effective and bevacizumab-containing chemotherapy was commenced. Both chemotherapy regimens produced favorable effects against the metastatic liver tumor, eliciting atrophic change regardless of the chemotherapy-free interval. One day the patient was admitted to our hospital because of black stool and hypotension. Upper gastrointestinal endoscopy revealed a beaded appearance of the gastroesophageal varix with bloody gastric contents. The portal hypertension might have been caused by changes in portal vein hemodynamics induced by the conformational changes underlying the favorable response of the liver tumor to molecular targeted chemotherapy and notable regression.

Guidelines for the management of iron deficiency anaemia.

PubMed

Goddard, Andrew F; James, Martin W; McIntyre, Alistair S; Scott, Brian B

2011-10-01

Iron deficiency anaemia (IDA) occurs in 2-5% of adult men and postmenopausal women in the developed world and is a common cause of referral to gastroenterologists. Gastrointestinal (GI) blood loss from colonic cancer or gastric cancer, and malabsorption in coeliac disease are the most important causes that need to be sought. DEFINING IRON DEFICIENCY ANAEMIA: The lower limit of the normal range for the laboratory performing the test should be used to define anaemia (B). Any level of anaemia should be investigated in the presence of iron deficiency (B). The lower the haemoglobin the more likely there is to be serious underlying pathology and the more urgent is the need for investigation (B). Red cell indices provide a sensitive indication of iron deficiency in the absence of chronic disease or haemoglobinopathy (A). Haemoglobin electrophoresis is recommended when microcytosis and hypochromia are present in patients of appropriate ethnic background to prevent unnecessary GI investigation (C). Serum ferritin is the most powerful test for iron deficiency (A). Upper and lower GI investigations should be considered in all postmenopausal female and all male patients where IDA has been confirmed unless there is a history of significant overt non-GI blood loss (A). All patients should be screened for coeliac disease (B). If oesophagogastroduodenoscopy (OGD) is performed as the initial GI investigation, only the presence of advanced gastric cancer or coeliac disease should deter lower GI investigation (B). In patients aged >50 or with marked anaemia or a significant family history of colorectal carcinoma, lower GI investigation should still be considered even if coeliac disease is found (B). Colonoscopy has advantages over CT colography for investigation of the lower GI tract in IDA, but either is acceptable (B). Either is preferable to barium enema, which is useful if they are not available. Further direct visualisation of the small bowel is not necessary unless there are symptoms suggestive of small bowel disease, or if the haemoglobin cannot be restored or maintained with iron therapy (B). In patients with recurrent IDA and normal OGD and colonoscopy results, Helicobacter pylori should be eradicated if present. (C). Faecal occult blood testing is of no benefit in the investigation of IDA (B). All premenopausal women with IDA should be screened for coeliac disease, but other upper and lower GI investigation should be reserved for those aged 50 years or older, those with symptoms suggesting gastrointestinal disease, and those with a strong family history of colorectal cancer (B). Upper and lower GI investigation of IDA in post-gastrectomy patients is recommended in those over 50 years of age (B). In patients with iron deficiency without anaemia, endoscopic investigation rarely detects malignancy. Such investigation should be considered in patients aged >50 after discussing the risk and potential benefit with them (C). Only postmenopausal women and men aged >50 years should have GI investigation of iron deficiency without anaemia (C). Rectal examination is seldom contributory, and, in the absence of symptoms such as rectal bleeding and tenesmus, may be postponed until colonoscopy. Urine testing for blood is important in the examination of patients with IDA (B). All patients should have iron supplementation both to correct anaemia and replenish body stores (B). Parenteral iron can be used when oral preparations are not tolerated (C). Blood transfusions should be reserved for patients with or at risk of cardiovascular instability due to the degree of their anaemia (C).

Lymphoma is a common malignancy observed in companion animals. This type of naturally occurring neoplasia has been uncommonly reported in great apes. Diffuse large B-cell lymphoma was diagnosed in an 8-yr-old captive orangutan (Pongo pygmaeus) with gastrointestinal disease by histologic and immunohistochemical methodologies. The orangutan was treated with three cycles of combination chemotherapy (intravenous Rituxan, cyclophosphamide, doxorubicin, and vincristine). The primate has been in good health and exhibiting normal behaviors for more than 15 mo following treatment.

Non-variceal upper gastrointestinal bleeding remains an important emergency condition, leading to significant morbidity and mortality. As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages. These include pre-endoscopy risk stratification scores, blood and platelet transfusion, use of proton pump inhibitors; during endoscopy new haemostasis techniques (haemostatic powder spray and over-the-scope clips); and post-endoscopy management by second-look endoscopy and medication strategies. Emerging techniques, including capsule endoscopy and Doppler endoscopic probe in assessing adequacy of endoscopic therapy, and the pre-emptive use of angiographic embolisation, are attracting new attention. An emerging problem is the increasing use of dual antiplatelet agents and direct oral anticoagulants in patients with cardiac and cerebrovascular diseases. Guidelines on the discontinuation and then resumption of these agents in patients presenting with NVUGIB are very much needed. The Asia-Pacific Working Group examined recent evidence and recommends practical management guidelines in this updated consensus statement. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal system. These types of tumors originate from any part of the tract as well as from the intestine, colon, omentum, mesentery or retroperitoneum. GIST is a rare tumor compared to other types of tumors, accounting for less than 1% of all gastrointestinal tumors. A 56-year-old male patient was hospitalized due to an upper gastrointestinal hemorrhage and the start of abdominal pain on the same day. In the upper gastrointestinal endoscopy that was performed, a solitary mass was found in the second section of the duodenum and a blood vessel (Forrest type 2a) was seen. The extent and location of the mass was detected by abdominal tomography. After hemodynamic recovery, a Whipple procedure was performed without any complications. A subsequent histopathological examination detected a c-kit-positive (CD117) pancreatic GIST with high mitotic index. The most effective treatment method for GISTs is surgical resection. In patients with a head of pancreatic GIST, the Whipple procedure can be used more safely and effectively.

The aim of the study is to examine the importance of Rockall scoring system in long-term setting to estimate re-bleeding and mortality rate due to upper gastrointestinal bleeding. A total of 321 patients who had been treated for upper gastrointestinal bleeding were recruited to the study. Patients' demographic and clinical data, the amount of blood transfusion, endoscopy results, and Rockall scores were retrieved from patients' charts. The re-bleeding, morbidity, and mortality rates were noted after 3 years of follow-up with telephone. Re-bleeding rate was statistically significantly higher in Rockall 4 group compared to Rockall 0 group. Mortality rate was also statistically significantly higher in Rockall 4 group. Rockall risk scoring system is a valuable tool to predict re-bleeding and mortality rates for patients with upper gastrointestinal bleeding in long-term setting.

Over the past three decades, transcatheter arterial embolization has become the first-line therapy for the management of acute nonvariceal upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the treatment of bleeding for a variety of indications. Transcatheter arterial embolization is a fast, safe, and effective minimally invasive alternative to surgery, when endoscopic treatment fails to control acute bleeding from the upper gastrointestinal tract. This article describes the role of arterial embolization in the management of acute nonvariceal upper gastrointestinal bleeding and summarizes the literature evidence on the outcomes of endovascular therapy in such a setting.

Selecting patients appropriately for upper endoscopy (EGD) is crucial for efficient use of endoscopy. The objective of this study was to compare different clinical strategies and statistical methods to select patients for EGD, namely appropriateness guidelines, age and/or alarm features, and multivariate and artificial neural network (ANN) models. A nationwide, multicenter, prospective study was undertaken in which consecutive patients referred for EGD during a 1-month period were enrolled. Before EGD, the endoscopist assessed referral appropriateness according to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines, also collecting clinical and demographic variables. Outcomes of the study were detection of relevant findings and new diagnosis of malignancy at EGD. The accuracy of the following clinical strategies and predictive rules was compared: (i) ASGE appropriateness guidelines (indicated vs. not indicated), (ii) simplified rule (>or=45 years or alarm features vs. <45 years without alarm features), (iii) logistic regression model, and (iv) ANN models. A total of 8,252 patients were enrolled in 57 centers. Overall, 3,803 (46%) relevant findings and 132 (1.6%) new malignancies were detected. Sensitivity, specificity, and area under the receiver-operating characteristic curve (AUC) of the simplified rule were similar to that of the ASGE guidelines for both relevant findings (82%/26%/0.55 vs. 88%/27%/0.52) and cancer (97%/22%/0.58 vs. 98%/20%/0.58). Both logistic regression and ANN models seemed to be substantially more accurate in predicting new cases of malignancy, with an AUC of 0.82 and 0.87, respectively. A simple predictive rule based on age and alarm features is similarly effective to the more complex ASGE guidelines in selecting patients for EGD. Regression and ANN models may be useful in identifying a relatively small subgroup of patients at higher risk of cancer.

Every gastrointestinal bleeding is an immediate threat to life, requiring close supervision in a hospital setting and making it mandatory to perform verification and endoscopic intervention. In some cases of a dynamic course, in order to make up deficiencies, it is necessary to use blood and blood products. One of the causes of bleeding located proximally to the ligament of Treitz is damage to the mucous membrane and deeper layers of the gastroesophageal junction, called Mallory-Weiss syndrome. The aim of the study was retrospective analysis of a selected group of patients with symptomatic upper gastrointestinal bleeding in the course of Mallory-Weiss syndrome, identification of typical characteristics of this disease entity in the studied population as well as demonstration of the effectiveness of endoscopic treatment using argon plasma coagulation (APC). The analysis included 2120 gastroscopy results, with 111 (5.24%) examinations conducted due to symptomatic gastrointestinal bleeding. In the studied group, endoscopic diagnosis of Mallory-Weiss syndrome was made in 22 patients (1.04%). The studied disease entity was the cause of upper gastrointestinal bleeding in 19.82% of cases. Although this condition is usually characterised by a mild and self-limiting course, 59.09% of patients in the studied group required therapeutic endoscopic intervention due to active bleeding. In 54.55%, argon plasma coagulation was successfully used to control the source of bleeding. Early gastroscopy, which remains both a diagnostic and therapeutic intervention, guarantees effective control of the clinical course of Mallory-Weiss syndrome. Endoscopic argon plasma coagulation is an effective way to treat bleeding, used in endoscopic monotherapy or in combination with other procedures.

Background & Aims Proton-pump inhibitors (PPIs) might reduce the risk of serious warfarin-related upper gastrointestinal bleeding, but the evidence of their efficacy for this indication is limited. A gastroprotective effect of PPIs would be particularly important for patients who take warfarin with antiplatelet drugs or nonselective non-steroidal anti-inflammatory drugs (NSAIDs), which further increase the risk of gastrointestinal bleeding. Methods This retrospective cohort study of patients beginning warfarin treatment in Tennessee Medicaid and the 5% National Medicare Sample identified 97,430 new episodes of warfarin treatment with 75,720 person-years of follow up. The study endpoints were hospitalizations for upper gastrointestinal bleeding potentially preventable by PPIs and for bleeding at other sites. Results Patients who took warfarin without PPI co-therapy had 119 hospitalizations for upper gastrointestinal bleeding per 10,000 person-years of treatment. The risk decreased by 24% among patients who received PPI co-therapy (adjusted hazard ratio [HR], 0.76; 95% CI, 0.63–0.91). There was no significant reduction in the risk of other gastrointestinal bleeding hospitalizations (HR, 1.07; 95% CI, 0.94–1.22) or non-gastrointestinal bleeding hospitalizations (HR, 0.98; 95% CI, 0.84–1.15) in this group. Among patients concurrently using antiplatelet drugs or NSAIDs, those without PPI co-therapy had 284 upper gastrointestinal bleeding hospitalizations per 10,000 person-years of warfarin treatment. The risk decreased by 45% (HR, 0.55; 95% CI, 0.39–0.77) with PPI co-therapy. PPI co-therapy had no significant protective effect for warfarin patients not using antiplatelet drugs or NSAIDs (HR, 0.86; 95% CI, 0.70-1.06). Findings were similar in both study populations. Conclusions In an analysis of patients beginning warfarin treatment in Tennessee Medicaid and the 5% National Medicare Sample, PPI co-therapy was associated with reduced risk of warfarin-related upper gastrointestinal bleeding; the greatest reduction occurred in patients also taking antiplatelet drugs or NSAIDs.

A gastroprotective effect of PPIs would be particularly important for patients who take warfarin with antiplatelet drugs or nonselective nonsteroidal anti-inflammatory drugs (NSAIDs), which further increase the risk of gastrointestinal bleeding. This retrospective cohort study of patients beginning warfarin treatment in Tennessee Medicaid and the 5% National Medicare Sample identified 97,430 new episodes of warfarin treatment with 75,720 person-years of follow-up. The study end points were hospitalizations for upper gastrointestinal bleeding potentially preventable by PPIs and for bleeding at other sites. Patients who took warfarin without PPI co-therapy had 119 hospitalizations for upper gastrointestinal bleeding per 10,000 person-years of treatment. The risk decreased by 24% among patients who received PPI co-therapy (adjusted hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.63-0.91). There was no significant reduction in the risk of other gastrointestinal bleeding hospitalizations (HR, 1.07; 95% CI, 0.94-1.22) or non-gastrointestinal bleeding hospitalizations (HR, 0.98; 95% CI, 0.84-1.15) in this group. Among patients concurrently using antiplatelet drugs or NSAIDs, those without PPI co-therapy had 284 upper gastrointestinal bleeding hospitalizations per 10,000 person-years of warfarin treatment. The risk decreased by 45% (HR, 0.55; 95% CI, 0.39-0.77) with PPI co-therapy. PPI co-therapy had no significant protective effect for warfarin patients not using antiplatelet drugs or NSAIDs (HR, 0.86; 95% CI, 0.70-1.06). Findings were similar in both study populations. In an analysis of patients beginning warfarin treatment in Tennessee Medicaid and the 5% National Medicare Sample, PPI co-therapy was associated with reduced risk of warfarin-related upper gastrointestinal bleeding; the greatest reduction occurred in patients also taking antiplatelet drugs or NSAIDs.

Gastrointestinal cancer is a group of tumors that affect multiple sites of the digestive system, including the stomach, liver, colon and pancreas. These cancers are very aggressive and rapidly metastasize, thus identifying effective targets is crucial for treatment. Galectin-1 (Gal-1) belongs to a family of glycan-binding proteins, or lectins, with the ability to cross-link specific glycoconjugates. A variety of biological activities have been attributed to Gal-1 at different steps of tumor progression. Herein, we summarize the current literature regarding the roles of Gal-1 in gastrointestinal malignancies. Accumulating evidence shows that Gal-1 is drastically up-regulated in human gastric cancer, hepatocellular carcinoma, colorectal cancer and pancreatic ductal adenocarcinoma tissues, both in tumor epithelial and tumor-associated stromal cells. Moreover, Gal-1 makes a crucial contribution to the pathogenesis of gastrointestinal malignancies, favoring tumor development, aggressiveness, metastasis, immunosuppression and angiogenesis. We also highlight that alterations in Gal-1-specific glycoepitopes may be relevant for gastrointestinal cancer progression. Despite the findings obtained so far, further functional studies are still required. Elucidating the precise molecular mechanisms modulated by Gal-1 underlying gastrointestinal tumor progression, might lead to the development of novel Gal-1-based diagnostic methods and/or therapies.

Background In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning. Aims To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis. Methods A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non‐surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease. Results A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13–2.10)) whereas age ⩾40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70–0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21–0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32–7.89)). Conclusions A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North‐South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres. PMID:16361306

We are reporting the first-to our knowledge-case of duodenal Plexiform Fibromyxoma causing obscure upper gastrointestinal bleeding. Plexiform fibromyxoma triggered recurrent upper gastrointestinal bleeding episodes in a 63-year-old man who remained undiagnosed, despite multiple hospitalizations, extensive diagnostic workups and surgical interventions (including gastrectomies), for almost 17 years. During hospitalization for the last bleeding episode, an upper gastrointestinal endoscopy revealed an intestinal hemorrhagic nodule. The lesion was deemed unresectable by endoscopic means. An abdominal computerized tomography disclosed no further lesions and surgery was decided. The lesion at operation was found near the edge of the duodenal stump and treated with pancreas-preserving duodenectomy (1st and 2nd portion). Postoperative recovery was mainly uneventful and a 20-month follow-up finds the patient in good health with no need for blood transfusions.Plexiform fibromyxomas stand for a rare and widely unknown mesenchymal entity. Despite the fact that they closely resemble other gastrointestinal tumors, they distinctly vary in clinical management as well as the histopathology. Clinical awareness and further research are compulsory to elucidate its clinical course and prognosis.

Background: Symptomatically ‘silent’ gastro-oesophageal reflux disease (GORD) may be underdiagnosed. Objective: To determine the prevalence of untreated GORD without heartburn and/or regurgitation in primary care. Methods: Patients were included if they had frequent upper gastrointestinal symptoms and had not taken a proton pump inhibitor in the previous 2 months (Diamond study: NCT00291746). GORD was diagnosed based on the presence of reflux oesophagitis, pathological oesophageal acid exposure, and/or a positive symptom–acid association probability. Patients completed the Reflux Disease Questionnaire (RDQ) and were interviewed by physicians using a prespecified symptom checklist. Results: GORD was diagnosed in 197 of 336 patients investigated. Heartburn and/or regurgitation were reported in 84.3% of patients with GORD during the physician interviews and in 93.4% of patients with GORD when using the RDQ. Of patients with heartburn and/or regurgitation not identified at physician interview, 58.1% (18/31) reported them at a ‘troublesome’ frequency and severity on the RDQ. Nine patients with GORD did not report heartburn or regurgitation either at interview or on the RDQ. Conclusions: Structured patient-completed questionnaires may help to identify patients with GORD not identified during physician interview. In a small proportion of consulting patients, heartburn and regurgitation may not be present in those with GORD. PMID:25360300

Risk of incident or recurrent malignancies among patients with rheumatoid arthritis exposed to biologic therapy in the German biologics register RABBIT

PubMed Central

2010-01-01

Introduction We used the data of the German biologics register RABBIT, a nationwide prospective cohort study, to investigate the risk of new or recurrent malignancy in patients with rheumatoid arthritis (RA) receiving biologics compared to conventional disease modifying anti-rheumatic drugs (DMARDs). Methods The analysis was based on patients with RA enrolled in RABBIT at the start of a biologic or conventional DMARD therapy between 01 May 2001 and 31 December 2006. Incidences of first or recurrent malignancies were analysed separately. A nested case-control design was used to investigate the risk of developing a first malignancy. Matching criteria were: age, gender, follow-up time, disease activity score based on 28 joint counts (DAS28) at study entry, smoking status, and selected chronic co-morbid conditions (obstructive or other lung disease, kidney, liver or gastrointestinal disease, psoriasis). Results A prior malignancy was reported in 122 out of 5,120 patients. Fifty-eight of these patients had received anti-TNFα agents, 9 anakinra, and 55 conventional DMARDs at study entry. In 14 patients (ever exposed to anti-TNFα: eight, to anakinra: one) 15 recurrent cancers were observed. The average time period since the onset of the first malignancy was nine years. Crude recurrence rates per 1,000 patient-years (pyrs) were 45.5 for patients exposed to anti-TNFα agents, 32.3 for anakinra patients and 31.4 for patients exposed to DMARDs only (Incidence rate ratio anti-TNFα vs. DMARD = 1.4, P = 0.6.). In patients without prior cancer, 74 patients (70% female, mean age: 61.3) developed a first malignancy during the observation. This corresponds to an incidence rate (IR) of 6.0/1,000 pyrs. Forty-four of these patients were ever exposed to anti-TNFα treatment (IR = 5.1/1,000 pyrs). In a nested case-control study comparing cancer patients to cancer-free controls, 44 of the cancer patients and 44 of the cancer-free controls were ever exposed to anti-TNFα agents (P = 1.0). Conclusions No significant differences in the overall incidence of malignancies in patients exposed or unexposed to anti-TNFα or anakinra treatment were found. The same applied to the risk of recurrent malignancies. However, in particular this last finding needs further validation in larger data sets. PMID:20064207

A 58-year-old Japanese male patient visited our hospital for evaluation of an elastic hard mass, measuring 80 x 50 mm, in the right axillary area. Incisional biopsy for suspected malignancy was performed, and histopathologic examination by hematoxylin-eosin (H&E) staining yielded a diagnosis of poorly differentiated adenocarcinoma metastatic from an unknown primary. As the tumor was immunohistochemically positive for both ER and PgR, metastatic breast cancer was strongly suspected. Ultrasonography, CT, and MRI revealed no evidence of tumors in the bilateral mammary glands. Detailed examination of the head and neck region, lung, and upper and lower gastrointestinal tract also revealed no evidence of a primary tumor. After chemotherapy, the patient underwent tumor resection with axillary lymph node dissection. On the basis of the histological features of H&E-stained specimens and immunohistochemistry of the resected tumor, this case was diagnosed as breast cancer of unknown origin in a male. The tumor could have been an axillary lymph node metastasis from an occult breast carcinoma, or primary cancer arising in an accessory mammary gland.

The impact of genomic profiling on the outcomes of patients with advanced gastrointestinal (GI) malignancies remains unknown. The primary objectives of the study were to investigate the clinical benefit of genomic-guided therapy, defined as complete response (CR), partial response (PR), or stable disease (SD) at 3 months, and its impact on progression-free survival (PFS) in patients with advanced GI malignancies. Clinical and genomic data of all consecutive GI tumor samples from April, 2013 to April, 2016 sequenced by FoundationOne were obtained and analyzed. A total of 101 samples from 97 patients were analyzed. Ninety-eight samples from 95 patients could be amplified making this approach feasible in 97% of the samples. After removing duplicates, 95 samples from 95 patients were included in the further analysis. Median time from specimen collection to reporting was 11 days. Genomic alteration-guided treatment recommendations were considered new and clinically relevant in 38% (36/95) of the patients. Rapid decline in functional status was noted in 25% (9/36) of these patients who could therefore not receive genomic-guided therapy. Genomic-guided therapy was utilized in 13 patients (13.7%) and 7 patients (7.4%) experienced clinical benefit (6 PR and 1 SD). Among these seven patients, median PFS was 10 months with some ongoing durable responses. Genomic profiling-guided therapy can lead to clinical benefit in a subset of patients with advanced GI malignancies. Attempting genomic profiling earlier in the course of treatment prior to functional decline may allow more patients to benefit from these therapies. © 2016 The Authors.

In the management of hematological malignancies, chemotherapy-induced mucositis is an increasingly recognized problem, leading to potentially severe clinical complications, treatment delays, increased costs and impairment of patient's quality of life. Many forms of cytotoxic treatments given in this setting may induce several degrees of mucositis. In particular, conditioning therapy with hematopoietic stem cell transplantation (HSCT) induces a disruption of the mucosal barrier function throughout the entire gastrointestinal tract facilitating the spreading of bacteria and endotoxin with subsequent increased risk of septicemia and, in the allogeneic setting, a worsening of Graft Versus Host Disease (GVHD). To review the role of palifermin and of other existing and potential treatments for chemotherapy-induced mucositis in the context of current knowledge of pathobiology in the setting of hematological malignancies. We searched for palifermin and mucositis of any region of the gastrointestinal tract using Medline; the abstract books of the most important hematological and oncological meetings were also reviewed. The pathobiology of mucositis is complex, and agents that target mechanisms to prevent mucositis or accelerate healing are highly required. In this regard, palifermin (recombinant human keratinocyte growth factor) has been demonstrated to reduce the severity and the duration of oral mucositis and to significantly improve several treatment outcomes in patients submitted to autologous HSCT; data are insufficient to recommend its use in the non-autologous HSCT settings, although interesting properties of this agent deserves other investigations in order to explore other possible indications.

Gastro-oesophageal reflux and dyspepsia are felt to be separate upper gastrointestinal (GI) conditions. We aimed to measure the degree of overlap between them, and assess whether endoscopic findings differed. Demographic, symptom, upper GI endoscopy and histology data were collected from consecutive adults in secondary care. Patients were categorised according to whether they reported gastro-oesophageal reflux alone, dyspepsia alone or both, and patient demographics and endoscopic findings were compared. Of 1167 patients, 97 (8.3%) had gastro-oesophageal reflux alone, 571 (48.9%) dyspepsia alone, and 499 (42.8%) overlap. Patients with overlap symptoms were more likely to smoke, compared with those with gastro-oesophageal reflux alone, or dyspepsia alone (p = .009), but there were no other differences. Patients with gastro-oesophageal reflux alone or overlap had a higher prevalence of erosive oesophagitis (18.6% and 15.4% respectively, p < .001), but this was still the commonest diagnosis among those with dyspepsia alone (7.2%). No significant differences were seen in prevalence of other endoscopic findings. Gastro-oesophageal reflux and dyspepsia symptoms commonly overlap. There were minimal differences in demographics or spectrum of underlying organic disease between various symptom groups, suggesting that restrictive classifications according to predominant symptom may not be clinically useful.

Non-steroidal anti-inflammatory drug related upper gastrointestinal bleeding: types of drug use and patient profiles in real clinical practice.

The best available evidence regarding non-steroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) bleeding comes from randomized controlled trials including patients who use NSAIDs to manage chronic rheumatic diseases; however, patients with varying background profiles commonly take NSAIDs for many other reasons, often without prescription, and such usage has not been well studied. To define the characteristics of patients hospitalized for upper GI bleeding in clinical practice, we conducted a case-control study among patients with endoscopy-proven major upper GI bleeding due to gastroduodenal peptic lesions and control subjects. We used adjusted logistic regression models to estimate bleeding risks. Data analysis was performed using SPSS 22.0. Our analysis included 3785 cases and 6540 controls, including 1270 cases (33.55%) and 834 controls (12.75%) reporting recent use (<30 days) of NSAIDs including high-dose acetylsalicylic acid (ASA). NSAID use was associated with increased risk of upper GI bleeding, with an adjusted relative risk of 4.86 (95% CI, 4.32-5.46). Acute musculoskeletal pain (36.1%), chronic osteoarthritis (13.5%), and headache (13.6%) were the most common reasons for NSAID use. Among cases, only 17.31% took NSAIDs and 6.38% took high dose ASA due to chronic osteoarthritis. Demographic characteristics significantly differed between subjects with chronic vs. acute musculoskeletal pain. Proton pump inhibitor use was significantly higher in patients who used NSAIDs due to chronic osteoarthritis compared to patients with acute musculoskeletal pain. NSAID (65.15%) or high-dose ASA use (65.83%) preceding upper GI bleeding was most often short-term. In over half of cases (63.62%), the upper GI bleeding event was not preceded by dyspeptic warning symptoms. The majority of patients hospitalized due to NSAID-related upper GI bleeding reported short-term NSAID use for reasons other than chronic rheumatic disease. These findings suggest that current prevention strategies may not reach a wide population of short-term NSAID users.

Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding. Copyright © 2014 Elsevier Inc. All rights reserved.

Henoch-Schönlein purpura (HSP) is the most common vascular disease of childhood. It is a multisystem disease most commonly affecting the skin,joints, gastrointestinal tract, and kidneys, but other organs may be affected, too. Gastrointestinal involvement occurs in approximately 65-90% of patients, ranging from mild symptoms such as abdominal pain, nausea, and vomiting, to more severe manifestations such as gastrointestinal bleeding and intussusception. In most cases, HSP spontaneously resolves without treatment. The use of corticosteroids is controversial and usually reserved for severe systemic manifestations. Some authors suggest that the abdominal pain and gastrointestinal hemorrhage of HSP may respond to steroids, with some suggesting that there is a benefit in their use and describing a regimen. This is a case report of HSP in a fourteen-year-old boy with abdominal pain and hematemesis. Upper endoscopy showed an edematous and erythematous change in the body of the stomach and purpuric lesions in the duodenum, while multiple erosions were found in the antral area. Parenteral corticosteroid therapy with gastric acid secretion inhibitor administration led to regression of gastrointestinal symptoms on the seventh day, with relapses on the fourth and sixth day. Peroral administration of corticosteroids and gradual decrease of daily doses started on the eighth day of abdominal symptoms. New purpuric skin rashes appeared during six weeks. Corticosteroid therapy with gastric acid secretion inhibitors showed a positive effect in our patient with a severe form of HSP accompanied by abdominal pain and gastrointestinal hemorrhage.

To investigate the clinical manifestations, diagnosis and treatment of gastric stromal tumors. 31 patients with gastric stromal tumors treated from 1993, 1 - 2001, 9 were analyzed retrospectively. All cases were diagnosed by pathological and immunohistochemistry examinations. According to Levin's standard combining with Hurliman's and Goldbum's methods, the patients were classified. There are no significant difference between male and female patients. 50 - 60 years old patients have high incidence. The distribution of gastric tromal tumors is fundus > body > antrum. Diagnosis of this condition is sometimes difficult and treatment is often delayed because patients usually present with nonspecific abdominal symptoms. The main manifestations of gastric stromal tumors are upper gastrointestinal hemorrhage 61.3% (19/31), 7 patients with acute hemorrhage and 12 with chronic hemorrhage. Most of them were malignant. Abdominal malaises and/or distention 32.3% (10/31) and abdominal pain 22.6% (7/31). Gastroscopy, ultrasound gastroscopy, computed tomography, B type ultrasound and upper gastrointestinal X-ray series are helpful to diagnosis. But the final diagnosis is decided by pathological and immunohistochemistry examinations. Gastric stromal tumors exhibit consistent immunohistochemical expressions of CD(117) and/or CD(34). The operative treatment is thought of the first choice. Effect of the chemotherapy isn't satisfied. There is no standard chemotherapy for gastric stromal tumors. Gastric stromal tumor is a kind of separated submucosal tumor which is different from leiomyoma, leiomyosarcoma and neurogenic tumors. Pathological and immunohistochemistry inspectations are very important to make clear diagnosis. Early diagnosis and rational treatment are the keys to improve the prognosis.

Bleeding of the upper gastrointestinal tract is the main symptom of a variety of possible conditions and still results in considerable mortality. Endoscopy is the first diagnostic modality, enabling rapid therapeutic intervention. In case of intractable or relapsing bleeding, surgery is often inevitable. However, emergency operations result in significantly higher mortality rates. Therefore the option of early elective surgical intervention should be considered for patients at increased risk of relapsing bleeding. If bleeding is symptomatic due to a complex underlying condition such as hemosuccus pancreaticus or hemobilia, angiography is now recognized as the definitive investigation. Angiographic hemostasis can be achieved in most cases. Due to the underlying condition, surgical management still remains the mainstay in treating these patients. This paper reviews surgical strategy in handling upper gastrointestinal bleeding.

Water utilities continue to be interested in implementing syndromic surveillance for the enhanced detection of waterborne disease outbreaks. The authors evaluated the ability of sales of over-the-counter diarrheal remedies available from the National Retail Data Monitor to predict endemic and epidemic gastrointestinal disease in the San Francisco Bay Area. Time series models were fit to weekly diarrheal remedy sales and diarrheal illness case counts. Cross-correlations between the pre-whitened residual series were calculated. Diarrheal remedy sales model residuals were regressed on the number of weekly outbreaks and outbreak-associated cases. Diarrheal remedy sales models were used to auto-forecast one week-ahead sales. The sensitivity and specificity of signals, generated by observed diarrheal remedy sales exceeding the upper 95% forecast confidence interval, in predicting weekly outbreaks were calculated. No significant correlations were identified between weekly diarrheal remedy sales and diarrhea illness case counts, outbreak counts, or the number of outbreak-associated cases. Signals generated by forecasting with the diarrheal remedy sales model did not coincide with outbreak weeks more reliably than signals chosen randomly. This work does not support the implementation of syndromic surveillance for gastrointestinal disease with data available though the National Retail Data Monitor.

The clinical importance of Crohn's disease (CD)-specific lesions in the upper gastrointestinal tract (upper GIT) has not been sufficiently established. The aim of this case-control study is to investigate the characteristic findings of CD in the upper GIT. In 2740 patients who underwent gastroduodenoscopy at Asahikawa Medical University between April 2011 and December 2012, 81 CD patients, 81 gender- and age-matched non-IBD patients, and 66 ulcerative colitis (UC) patients were investigated in the present study. (1) The diagnostic ability and odds ratio of each endoscopic finding (a bamboo joint-like appearance in the cardia, erosions, and/or ulcers in the antrum, notched signs, and erosions and/or ulcers in the duodenum) were compared between the CD and non-IBD patients or UC patients. (2) The interobserver agreement of the diagnosis based on the endoscopic findings was evaluated by 3 experienced and 3 less-experienced endoscopists. The incidence of detecting a bamboo joint-like appearance, notched signs, and erosions and/or ulcers in the duodenum was significantly higher in the CD patients than in the non-IBD and UC patients. In addition, the diagnostic ability and odds ratio of a bamboo joint-like appearance for CD were higher than those for the other findings. Kendall's coefficients of concordance in the group of experienced and less-experienced endoscopists were relatively high for a bamboo joint-like appearance (0.748 and 0.692, respectively). A cardiac bamboo joint-like appearance is a useful finding for identifying high-risk groups of CD patients using only gastroduodenoscopy.

It is difficult to assess risk in normotensive patients with upper gastrointestinal bleeding. The aim of this study was to evaluate whether the initial lactate value can predict the in-hospital occurrence of hypotension in stable patients with acute nonvariceal upper gastrointestinal bleeding. Retrospective, observational, single-center study. Emergency department of a tertiary-care, university-affiliated hospital during a 5-year period. Medical records of 3,489 patients with acute upper gastrointestinal bleeding who were normotensive at presentation to the emergency department. We analyzed the ability of point-of-care testing of lactate at emergency department admission to predict hypotension development (defined as systolic blood pressure <90 mm Hg) within 24 hours after emergency department admission. None. Of the 1,003 patients with acute nonvariceal upper gastrointestinal bleeding, 157 patients experienced hypotension within 24 hours. Lactate was independently associated with hypotension development (odds ratio, 1.6; 95% CI, 1.4-1.7), and the risk of hypotension significantly increased as the lactate increased from 2.5-4.9 mmol/L (odds ratio, 2.2) to 5.0-7.4 mmol/L (odds ratio, 4.0) and to greater than or equal to 7.5 mmol/L (odds ratio, 39.2) (p<0.001). Lactate elevation (≥2.5 mmol/L) was associated with 90% specificity and an 84% negative predictive value for hypotension development. When the lactate levels were greater than 5.0 mmol/L, the specificity and negative predictive value increased to 98% and 87%, respectively. Point-of-care testing of lactate can predict in-hospital occurrence of hypotension in stable patients with acute nonvariceal upper gastrointestinal bleeding. However, subsequently, prospective validate research will be required to clarify this.

Purpose To identify the characteristics and evaluate the long-term outcomes of endovascular treatment of Budd-Chiari syndrome with upper gastrointestinal hemorrhage. Methods Forty-seven consecutive Budd-Chiari syndrome patients with upper gastrointestinal hemorrhage were referred for the treatment with percutaneous transluminal balloon angioplasty, and subsequently underwent follow-up. Data were retrospectively collected and follow-up observations were performed at 1, 2, 2-5, and 5-8 years postoperatively. Results Cirrhosis was presented in 16 patients, and splenoportography reviewed obvious varices in 18 patients. Percutaneous transluminal balloon angioplasty was technically successful in all patients. Major procedure-related complications occurred in 3 of the 47 patients (6.38%). The cumulative 1, 2, 2-5, and 5-8 year primary patency rates were 100% (46/46), 93.2% (41/44), 90.9% (40/44), and 86.4% (19/22), respectively. The cumulative 1, 2, 2-5, and 5-8 year secondary patency rates were 100% (47/47), 100% (44/44), 100% (44/44), and 95.5% (21/22), respectively. Mean and median duration of primary patency was 65.17 ± 3.78 and 69.0 ± 5.69 months, respectively. No upper gastrointestinal hemorrhage recurred during follow-ups. The mean survival time was 66.97 ± 3.61 months and the median survival time was 69.0 ± 4.10 months. Conclusion PTBA was an effective treatment that can prevent recurrence of the life-threatening complications and ensured long-term satisfactory clinical outcomes for Budd-Chiari syndrome patients with upper gastrointestinal hemorrhage. Percutaneous transhepatic variceal embolization was not recommended for all Budd-Chiari syndrome patients with upper gastrointestinal hemorrhage.

Multiple scoring systems have been developed to predict outcomes in patients with upper gastrointestinal bleeding. We determined how well these and a newly established scoring model predict the need for therapeutic intervention, excluding transfusion, in Japanese patients with upper gastrointestinal bleeding. We reviewed data from 212 consecutive patients with upper gastrointestinal bleeding. Patients requiring endoscopic intervention, operation, or interventional radiology were allocated to the therapeutic intervention group. Firstly, we compared areas under the curve for the Glasgow-Blatchford, Clinical Rockall, and AIMS65 scores. Secondly, the scores and factors likely associated with upper gastrointestinal bleeding were analyzed with a logistic regression analysis to form a new scoring model. Thirdly, the new model and the existing model were investigated to evaluate their usefulness. Therapeutic intervention was required in 109 patients (51.4%). The Glasgow-Blatchford score was superior to both the Clinical Rockall and AIMS65 scores for predicting therapeutic intervention need (area under the curve, 0.75 [95% confidence interval, 0.69-0.81] vs 0.53 [0.46-0.61] and 0.52 [0.44-0.60], respectively). Multivariate logistic regression analysis retained seven significant predictors in the model: systolic blood pressure <100 mmHg, syncope, hematemesis, hemoglobin <10 g/dL, blood urea nitrogen ≥22.4 mg/dL, estimated glomerular filtration rate ≤ 60 mL/min per 1.73 m 2 , and antiplatelet medication. Based on these variables, we established a new scoring model with superior discrimination to those of existing scoring systems (area under the curve, 0.85 [0.80-0.90]). We developed a superior scoring model for identifying therapeutic intervention need in Japanese patients with upper gastrointestinal bleeding. © 2016 Japan Gastroenterological Endoscopy Society.

Bleeding with the artificial heart: Gastrointestinal hemorrhage in CF-LVAD patients.

Continuous-flow left ventricular assist devices (CF-LVADs) have significantly improved outcomes for patients with end-stage heart failure when used as a bridge to cardiac transplantation or, more recently, as destination therapy. However, its implantations carries a risk of complications including infection, device malfunction, arrhythmias, right ventricular failure, thromboembolic disease, postoperative and nonsurgical bleeding. A significant number of left ventricular assist devices (LVAD) recipients may experience recurrent gastrointestinal hemorrhage, mainly due to combination of antiplatelet and vitamin K antagonist therapy, activation of fibrinolytic pathway, acquired von Willebrand factor deficiency, and tendency to develop small intestinal angiodysplasias due to increased rotary speed of the pump. Gastrointestinal bleeding in LVAD patients remains a source of increased morbidity including the need for blood transfusions, extended hospital stays, multiple readmissions, and overall mortality. Management of gastrointestinal bleeding in LVAD patients involves multidisciplinary approach in stabilizing the patients, addressing risk factors and performing structured endoluminal evaluation with focus on upper gastrointestinal tract including jejunum to find and eradicate culprit lesion. Medical and procedural intervention is largely successful and universal bleeding cessation occurs in transplanted patients.

Particle Radiation Therapy for Gastrointestinal Malignancies

Meyer, Jeffrey J.; Willett, Christopher G.

2007-01-01

Treatment-related toxicity is common in the radiotherapeutic management of cancers of the gastrointestinal tract. These toxicities can diminish treatment efficacy by necessitating treatment breaks, limiting the radiation dose that can be delivered, and hindering concomitant use of chemotherapy and targeted drug agents. Many efforts have focused on widening the gap between the likelihood of tumor control and the likelihood of toxicities associated with radiation. Use of particles that exhibit a Bragg peak phenomenon in their interactions with tissue, such as protons, heavier ions like carbon ions, and pions, is one means of concentrating radiation dose in tumors and away from normal tissues. Neutron beams have also been used in the treatment of gastrointestinal cancers in an effort to take advantage of their potent biologic effects. This report reviews basic particle radiation physics and biology, as well as the clinical experience with protons, heavier ions, pions, and neutrons in the treatment of various gastrointestinal malignancies. Potential future directions in clinical research with particle therapy are discussed. PMID:19360149

Acute gastrointestinal bleeding (GIB) can lead to significant morbidity and mortality without appropriate treatment. There are numerous causes of acute GIB including but not limited to infection, vascular anomalies, inflammatory diseases, trauma, and malignancy. The diagnostic and therapeutic approach of GIB depends on its location, severity, and etiology. The role of interventional radiology becomes vital in patients whose GIB remains resistant to medical and endoscopic treatment. Radiology offers diagnostic imaging studies and endovascular therapeutic interventions that can be performed promptly and effectively with successful outcomes. Computed tomography angiography and nuclear scintigraphy can localize the source of bleeding and provide essential information for the interventional radiologist to guide therapeutic management with endovascular angiography and transcatheter embolization. This review article provides insight into the essential role of Interventional Radiology in the management of acute GIB. PMID:24778770

The main object of this work was to determine the role and place of esophagogastroduodenoscopy (EGDS) in the diagnostic diseases upper portion of the gastrointestinal tract. We analysed endoscopic pictures of patients, which have HIV and active form of tuberculosis (T. B.). 141 patients with HIV/T. B., who are on the treatment in Tubercular hospital No 11 of Moscow, were examined during 2008 year. About 86% of patients (121 of 141) had a positive endoscopic picture of gastroesophageal reflux disease (GERB). About 69.5% of patients had a mycotic lesion of esophagus: 52 patients (17.8%) had a mycotic lesion of esophagus, which was visually discovered by EGDS; mycotic lesion of esophagus was confirmed by method of polymerase chain reaction (PCR (at 46 patients (51.7%)). The smear for identification micobacteria of tuberculosis was taken from 52 patients (from group 89 patients) with negative endoscopic picture of a mycotic lesion by method PCR additionally. The results have shown, that 23 patients have a positive reaction (43.4%). A diagnostic bronchoscopy was made to examed group. 20 patients from 141 with HIV (14.9%) had a positive result PCR of mycotic lesion. It shows that a defeat of candidosis take place not only in the gastrointestinal tract, but also in the bronchial tree. EGDS+ PCR+ histology is the basis method of the diagnostic diseases upper portion of the gastrointestinal tract. This research established that almost 70% of patients with HIV/T. B. have mycotic lesion of esophagus and 86%--defeat of GERB. That's why, we recommend to include proton- pump inhibitors and antimycotic preparations in the scheme of patient's treatment.

Hemospray is a new endoscopic haemostatic powder that can be used in the management of upper gastrointestinal bleedings. To assess the efficacy and safety of Hemospray as monotherapy for the treatment of acute upper gastrointestinal bleeding due to cancer. The endoscopy databases of 3 Italian Endoscopic Units were reviewed retrospectively and 15 patients (8 males; mean age 74 years) were included in this study. Immediate haemostasis was achieved in 93% of cases. Among the successful cases, 3 re-bled, one case treated with Hemospray and injection had a good outcome, while 2 cases died both re-treated with Hemospray, injection and thermal therapy. No complications related to Hemospray occurred. Finally, 80% of patients had a good clinical outcome at 30days and 50% at six months. Hemospray may be considered an effective and safe method for the endoscopic management of acute neoplastic upper gastrointestinal bleedings.

1999-01-01

Objective To examine the association between selective serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding. Design Population based case-control study. Setting General practices included in the UK general practice research database. Subjects 1651 incident cases of upper gastrointestinal bleeding and 248 cases of ulcer perforation among patients aged 40 to 79 years between April 1993 and September 1997, and 10 000 controls matched for age, sex, and year that the case was identified. Interventions Review of computer profiles for all potential cases, and an internal validation study to confirm the accuracy of the diagnosis on the basis of the computerised information. Main outcome measures Current use of selective serotonin reuptake inhibitors or other antidepressants within 30 days before the index date. Results Current exposure to selective serotonin reuptake inhibitors was identified in 3.1% (52 of 1651) of patients with upper gastrointestinal bleeding but only 1.0% (95 of 10 000) of controls, giving an adjusted rate ratio of 3.0 (95% confidence interval 2.1 to 4.4). This effect measure was not modified by sex, age, dose, or treatment duration. A crude incidence of 1 case per 8000 prescriptions was estimated. A small association was found with non-selective serotonin reuptake inhibitors (relative risk 1.4, 1.1 to 1.9) but not with antidepressants lacking this inhibitory effect. None of the groups of antidepressants was associated with ulcer perforation. The concurrent use of selective serotonin reuptake inhibitors with non-steroidal anti-inflammatory drugs increased the risk of upper gastrointestinal bleeding beyond the sum of their independent effects (15.6, 6.6 to 36.6). A smaller interaction was also found between selective serotonin reuptake inhibitors and low dose aspirin (7.2, 3.1 to 17.1). Conclusions Selective serotonin reuptake inhibitors increase the risk of upper gastrointestinal bleeding. The absolute effect is, however, moderate and about equivalent to low dose ibuprofen. The concurrent use of non-steroidal anti-inflammatory drugs or aspirin with selective serotonin reuptake inhibitors greatly increases the risk of upper gastrointestinal bleeding. PMID:10531103

Refractory gastro-oesophageal reflux disease: diagnosis and management.

PubMed

Liu, Julia J; Saltzman, John R

2009-10-01

Refractory gastro-oesophageal reflux disease (GORD) is described when reflux symptoms have not responded to 4-8 weeks of proton pump inhibitor therapy and occurs in a heterogeneous mixture of patients. The causes of refractory GORD include inadequate acid suppression, non-acid gastro-oesophageal reflux, and non-reflux causes of GORD symptoms including achalasia, gastroparesis and functional heartburn. Upper gastrointestinal tract endoscopy should initially be performed to identify the presence of oesophagitis, and exclude other diagnoses including eosinophilic oesophagitis and peptic ulcer disease. Patients with refractory symptoms but with a normal upper endoscopy are more difficult to diagnose and may require ambulatory pH monitoring, impedance testing, oesophageal motility tests and gastric emptying scans. The primary goal of treatment is symptom reduction and eventual elimination, which can be achieved with proper identification of the underlying cause of the symptoms.

Background: Gall bladder carcinoma accounts for 98% of all the gall bladder malignancies and it is the sixth most common malignancy of the gastrointestinal tract worldwide. The incidence of incidental gall bladder carcinoma which is diagnosed during or after a laparoscopic cholecystectomy is reported to be around 0.19-3.3% in the literature. Aim: This study was aimed at detecting the incidence of gall bladder carcinomas which were diagnosed incidentally during or after laparoscopic cholecystectomies which were done for gall stone disease and cholecystitis. Materials and Methods: We analyzed the medical records of patients with symptomatic gallstone disease and acute or chronic cholecystitis, who underwent laparoscopic cholecystectomies at the Hakeem Abdul Hameed Centenary Hospital during the period from January 2007 to June 2012. Results: A total of 622 laparoscopic cholecystectomies were performed at our institute during the study period of five and a half years. In 6 (0.96%) cases, incidental carcinomas of the gallbladder were discovered. Conclusion: A laparoscopic cholecystectomy which is performed for benign gall bladder disease rarely results in a diagnosis of unexpected gallbladder cancer. The microscopic examination of the specimens, with special attention to the depth of invasion, range of the mucosal spread and the lymphovascular involvement, is critical in diagnosing the incidental malignancies as well as for the subsequent management of the cases.

Peritoneal tumour dissemination is still considered as a terminal disease. For the last two decades, cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy (HIPEC) has been popularised by Paul Sugarbaker almost doubling survival in selected patients compared with systemic chemotherapy alone. Nowadays, this particular treatment protocol is available in comprehensive cancer centres with reasonable mortality and morbidity. However, patient selection is still challenging. In general, CRS and HIPEC is indicated in primary peritoneal tumours such as mesothelioma and pseudomyxoma peritonei as well as in peritoneal metastases derived from gastrointestinal malignancies and ovarian cancers. Since systemic tumour spread is uncommon in patients with peritoneal metastases, peritoneal tumour dissemination was defined as localised disease within the "compartment abdomen". However, CRS and HIPEC are only beneficial as long as complete cytoreduction is achieved (CC-0 or CC-1). Histopathological parameters, the Sugarbaker peritoneal carcinomatosis index (PCI) and general condition of the patient have been established as patient selection criteria. In primary peritoneal cancers, individual tumour biology is the predominant criterium for patient selection as opposed to intraabdominal tumour load in peritoneal metastases derived from gastrointestinal cancers. In gastric cancer, CRS and HIPEC should be restricted to synchronous limited disease because of its biological aggressiveness. In patients with free floating cancer cells without macroscopic signs of peritoneal spread, however, CRS and HIPEC following preoperative "neoadjuvant" chemotherapy preserves chances for cure. So far, there is no general recommendation for CRS and HIPEC by clinical practice guidelines. In the recent S3 guideline for treatment of colorectal cancer, however, CRS and HIPEC have been included as possible treatment options. Georg Thieme Verlag KG Stuttgart · New York.

Since the middle of the last century, North America and occidental countries have reported variations in the frequency of gastrointestinal neoplasms. Several environmental factors, mainly nutritional and dietary exposure, as well as habits have contributed to these changes. We have documented these changes in Mexico during the last 35 years. To define the epidemiologic changes of gastrointestinal neoplasms during the last three decades in our population. We summarized the evidence of an observational study, registering the frequency of different gastrointestinal malignancies from four institutions of socioeconomically different populations in Mexico City during 35 years. The Mexican National Academy of Medicine supported this effort. During this period, two nutritional surveys took place, letting us define the relationship between dietary changes and cancer occurrence. Replacement of gastric cancer by colorectal cancer as the leading gastrointestinal malignancy. Relationship between cancer and diet changes. Increase of esophageal adenocarcinoma in relation to epidermoid carcinoma secondary to gastroesophageal reflux and Barrett's esophagus rising incidence. Gall bladder cancer had a high frequency in one institution, probably related to genetic and racial factors. This epidemiologic data should lead us to implement sanitary measures for the prevention, early diagnosis, and appropriate treatment of gastrointestinal neoplasms.

Upper gastrointestinal bleeding (UGIB) is a common emergency gastrointestinal problem which has substantial mortality and health care resources use. The nationwide basic information on UGIB is not available in Thailand. To identify the hospitalized incidence, outcomes and hospitalization cost of patients who presented with UGIB in Thailand. Information on illness of in-patients from hospitals nationwide was retrieved from three major health schemes database in fiscal year 2010. The hospitalized incidence rate of UGIB was 166.3 admissions per 100,000 populations and the hospitalized incidence rate of non-variceal upper gastrointestinal bleeding (NVUGIB) and variceal bleeding were 152.9 and 13.5 admissions per 100,000 populations respectively. Endoscopic procedure was undertaken in 27.6% of NVUGIB admissions and 80.7% of variceal bleeding admissions. The in-hospital mortality rate, hospitalization cost and length of stay were higher in variceal bleeding patients compared with NVUGIB patients. UGIB is an important emergency gastrointestinal problem which has significant mortality and substantial health care resources consumption.

BACKGROUND Surgical site infections (SSIs) remain a major source of morbidity and cost after resection of intra-abdominal malignancies. Negative-pressure wound therapy (NPWT) has been reported to significantly reduce SSIs when applied to the closed laparotomy incision. This article reports the results of a randomized clinical trial examining the effect of NPWT on SSI rates in surgical oncology patients with increased risk for infectious complications. STUDY DESIGN From 2012 to 2016, two hundred and sixty-five patients who underwent open resection of intra-abdominal neoplasms were stratified into 3 groups: gastrointestinal (n = 57), pancreas (n = 73), or peritoneal surface (n = 135) malignancy. They were randomized to receive NPWT or standard surgical dressing (SSD) applied to the incision from postoperative days 1 through 4. Primary outcomes of combined incisional (superficial and deep) SSI rates were assessed up to 30 days after surgery. RESULTS There were no significant differences in superficial SSIs (12.8% vs 12.9%; p > 0.99) or deep SSI (3.0% vs 3.0%; p > 0.99) rates between the SSD and NPWT groups, respectively. When stratified by type of surgery, there were still no differences in combined incisional SSI rates for gastrointestinal (25% vs 24%; p > 0.99), pancreas (22% vs 22%; p > 0.99), and peritoneal surface malignancy (9% vs 9%; p > 0.99) patients. When performing univariate and multivariate logistic regression analysis of demographic and operative factors for the development of combined incisional SSI, the only independent predictors were preoperative albumin (p = 0.0031) and type of operation (p = 0.018). CONCLUSIONS Use of NPWT did not significantly reduce incisional SSI rates in patients having open resection of gastrointestinal, pancreatic, or peritoneal surface malignancies. Based on these results, at this time NPWT cannot be recommended as a therapeutic intervention to decrease infectious complications in these patient populations. PMID:28088597

The Rockall risk scoring system uses clinical criteria and endoscopy to identify patients at risk of adverse outcomes after acute upper gastrointestinal haemorrhage. A clinical Rockall score obtained using only the clinical criteria may be able to predict outcome without endoscopy. To validate the clinical Rockall Score in predicting outcome after acute non-variceal upper gastrointestinal haemorrhage. A retrospective observational study of consecutive patients who were admitted with non-variceal acute upper gastrointestinal haemorrhage was undertaken. Medical records were abstracted using a standardised form. 102 cases were identified (51 men and 51 women; mean age 59 years). 38 (37%) patients considered to be at low risk of adverse outcomes (clinical Rockall Score 0) had no adverse outcomes and did not require transfusion. Patients with a clinical Rockall Score of 1-3 had no adverse outcomes, although 13 of 45 (29%) patients required blood transfusions. Clinical Rockall Scores >3 (n = 19) were associated with adverse outcomes (rebleeding in 4 (21%), surgery in 1 (5%) and death in 2 (10%)). The clinical Rockall Score without endoscopy may be a useful prognostic indicator in this cohort of patients with acute non-variceal upper gastrointestinal haemorrhage. This score may reduce the need for urgent endoscopy in low-risk patients, which can instead be carried out on a more elective outpatient basis.

Malignant phaeochromocytomas are rare and highly aggressive tumours. This retrospective study evaluated the outcome of combined chemotherapy with cyclophosphamide, vincristine and dacarbazine (also known as CVD regimen). Patients with histologically and radiologically confirmed malignant phaeochromocytoma who were treated with the CVD regimen for progressive disease were retrospectively identified from chart review. Treatment cycles were usually repeated at 21-day intervals, with cyclophosphamide (750 mg/m(2) ), vincristine (1·4 mg/m(2) ) and dacarbazine (600 mg/m(2) ) on day 1, and dacarbazine only (600 mg/m(2) ) on day 2. The main outcome measures were best response during treatment and progression-free survival. Eight patients (4 males; median age 55·5 (range 31-77) years) with progressive disease underwent a median of 6 (range 3-11) cycles. Best treatment responses were as follows: partial response, n = 2 (25%); stable disease, n = 3 (38%); and progressive disease, n = 3 (38%). The median progression-free survival was 5·4 (range 2·5-26·8) months. After the initial administration of 6 cycles, two patients received a second course of chemotherapy with another 6 cycles after new progressive disease had been detected. Subsequently, these patients were progression-free for another 6·0 and 6·4 months. Mild gastrointestinal symptoms and fatigue were the most common adverse events. Although objective tumour response rates were lower than previously reported in small series, the CVD regimen allowed disease stabilization for a substantial period of time and may therefore be considered as a treatment option in advanced stages. To improve disease outcome, however, new therapeutic approaches and larger multicentre studies are needed. © 2014 John Wiley & Sons Ltd.

Malignant pheochromocytoma is a rare disorder. We describe the case of a 41-year-old female with disseminated metastatic pheochromocytoma who was admitted for ongoing palliative and supportive care within an inpatient palliative care unit. Predominant symptoms included severe gastrointestinal pseudo-obstruction and orthostatic hypotension Pseudo-obstruction management included percutaneous enterogastric and percutaneous enterojejunostomy tubes for gastric decompression and delivery of nutrition, respectively. Debilitating symptoms of orthostatic hypotension were mitigated with judicious fluid balance and appropriate use of adrenergic blocking agents. The potential for metoclopramide to worsen symptoms also was a significant component of management. The case presents rare features of this unusual disease and is unique for its setting within the confines of a palliative care unit. Crown Copyright © 2012. Published by Elsevier Inc.

To obtain prospective outcomes data on patients (pts) undergoing palliative operative or endoscopic procedures for malignant bowel obstruction due to recurrent ovarian cancer. An institutional study was conducted from July 2002 to July 2003 to prospectively identify pts who underwent an operative or endoscopic procedure to palliate the symptoms of advanced cancer. This report focuses on pts with malignant bowel obstruction due to recurrent ovarian cancer. Procedures performed with an upper or lower gastrointestinal (GI) endoscope were considered "endoscopic." All other cases were classified as "operative." Following the procedure, the presence or absence of symptoms was determined and followed over time. All pts were followed until death. Palliative interventions were performed on 74 gynecologic oncology pts during the study period, of which 26 (35%) were for malignant GI obstruction due to recurrent ovarian cancer. The site of obstruction was small bowel in 14 (54%) cases and large bowel in 12 (46%) cases. Palliative procedures were operative in 14 (54%) pts and endoscopic in the other 12 (46%). Overall, symptomatic improvement or resolution within 30 days was achieved in 23 (88%) of 26 patients, with 1 (4%) postprocedure mortality. At 60 days, 10 (71%) of 14 pts who underwent operative procedures and 6 (50%) of 12 pts who had endoscopic procedures had symptom control. Median survival from the time of the palliative procedure was 191 days (range, 33-902) for those undergoing an operative procedure and 78 days (range, 18-284) for those undergoing an endoscopic procedure. Patients with malignant bowel obstructions due to recurrent ovarian cancer have a high likelihood of experiencing relief of symptoms with palliative procedures. Although recurrence of symptoms is common, durable palliation and extended survival are possible, especially in those patients selected for operative intervention.

The epithelial cell adhesion molecule (EpCAM) is overexpressed in a wide variety of tumor types, including peritoneal carcinomatosis (PC) from gastrointestinal and gynecological malignancies. To develop a chimeric antigen receptor T (CART) cell therapy approach to treat patients with end-stage PC, we constructed third generation CARs specific to EpCAM using the 4D5MOC-B single chain variable fragment. CART cells were generated with lentiviral transduction and exhibited specific in vitro killing activity against EpCAM-positive human ovarian and colorectal cancer cells. A single intraperitoneal injection of the CART cells eradicated established ovarian xenografts and resulted in significantly prolonged animal survival. Since EpCAM is also expressed on normal epithelium, anti-EpCAM CART cells were generated by mRNA electroporation that display a controlled cytolytic activity with a limited CAR expression duration. Multiple repeated infusions of these RNA CAR-modified T cells delayed disease progression in immunodeficient mice bearing well-established peritoneal ovarian and colorectal xenografts. Thus, our study demonstrates the effectiveness of using anti-EpCAM CAR-expressing T cells for local treatment of PC in mice. The possibility of using this approach for clinical treatment of EpCAM-positive gastrointestinal and gynecological malignancies warrants further validation. PMID:28088790

The mortality experience of 1074 white men who retired from a United States asbestos company during the period 1941-67 and who were exposed to asbestos working as production and maintenance employees for the company is reported to the end of 1980 when 88% of this cohort was known to be dead. As noted in earlier reports the mortality for respiratory and gastrointestinal cancer was raised. A more detailed examination of causes of death shows that the excess in gastrointestinal cancer was largely due to a statistically significant excess in stomach cancer. A statistically significant excess was also noted for kidney cancer, cancer of the eye, and non-malignant respiratory disease. Eight deaths from malignant mesothelioma were observed, two of which were peritoneal. Asbestos exposures for these mesothelioma cases were low relative to other members of the cohort. Continuing follow up of this cohort shows a dose response relation for respiratory cancer that has become increasingly linear. Standardised mortality ratios peaked 10 to 15 years after retirement and were relatively constant at around 250 in each five year interval starting in 1950. This excess might have been detected as early as 1960 but certainly by 1965. The mortality experience of this cohort reflects the ultimate effects of asbestos since nearly all of the cohort has now died. PMID:3606968

To investigate the preventive effects of low-dose proton-pump inhibitors (PPIs) for upper gastrointestinal bleeding (UGIB) in end-stage renal disease. This was a retrospective cohort study that reviewed 544 patients with end-stage renal disease who started dialysis at our center between 2005 and 2013. We examined the incidence of UGIB in 175 patients treated with low-dose PPIs and 369 patients not treated with PPIs (control group). During the study period, 41 patients developed UGIB, a rate of 14.4/1000 person-years. The mean time between the start of dialysis and UGIB events was 26.3 ± 29.6 mo. Bleeding occurred in only two patients in the PPI group (2.5/1000 person-years) and in 39 patients in the control group (19.2/1000 person-years). Kaplan-Meier analysis of cumulative non-bleeding survival showed that the probability of UGIB was significantly lower in the PPI group than in the control group (log-rank test, P < 0.001). Univariate analysis showed that coronary artery disease, PPI use, anti-coagulation, and anti-platelet therapy were associated with UGIB. After adjustments for the potential factors influencing risk of UGIB, PPI use was shown to be significantly beneficial in reducing UGIB compared to the control group (HR = 13.7, 95%CI: 1.8-101.6; P = 0.011). The use of low-dose PPIs in patients with end-stage renal disease is associated with a low frequency of UGIB.

Perforation peritonitis is the most common surgical emergency encountered by the surgeons all over the world as well in Pakistan. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counter part. This study was conducted at Dow University of health sciences and Civil Hospital Karachi (DUHS & CHK) Pakistan, designed to highlight the spectrum of perforation peritonitis in the East and to improve its outcome. A prospective study includes three hundred consecutive patients of perforation peritonitis studied in terms of clinical presentations, Causes, site of perforation, surgical treatment, post operative complications and mortality, at (DUHS&CHK) Pakistan, from 1st September 2005 - 1st March 2008, over a period of two and half years. All patients were resuscitated underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled. The most common cause of perforation peritonitis noticed in our series was acid peptic disease 45%, perforated duodenal ulcer (43.6%) and gastric ulcer 1.3%. followed by small bowel tuberculosis (21%) and typhoid (17%). large bowel perforation due to tuberculosis 5%, malignancy 2.6% and volvulus 0.3%. Perforation due to acute appendicitis (5%). Highest number of perforations has seen in the duodenum 43.6%, ileum37.6%, and colon 8%, appendix 5%, jejunum 3.3%, and stomach 2.3%. Overall mortality was (10.6%). The spectrum of perforation peritonitis in Pakistan continuously differs from western country. Highest number of perforations noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. Most common cause of perforation peritonitis is perforated duodenal ulcer, followed by small bowel tuberculosis and typhoid perforation. Majority of the large bowel perforations are also tubercular. Malignant perforations are least common in our setup.

Alpha-fetoprotein-producing esophageal adenocarcinoma: a mimicker of hepatocellular carcinoma.

2017-02-01

Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transaminitis and AFP was 2524 ng/mL. Computed tomography of the abdomen revealed abnormal thickening of the esophagus and multiple metastatic masses throughout the liver. Biopsy of one of the masses revealed adenocarcinoma of gastrointestinal origin. Subsequent upper endoscopy revealed an esophageal mass with biopsy notable for ulcerated dysplastic glandular mucosa with likely underlying malignancy. The patient underwent palliative esophageal stent placement but died two months later. Elevated AFP levels are an unusual occurrence in EAC. Prognosis is poor given its advanced presenting stage and high metastatic potential. Most cases are unsuccessfully treated with surgery and chemotherapy. Serial measurement of serum AFP may be useful for monitoring clinical status and treatment response. Clinicians should consider AFP-producing EAC in their differential diagnosis in the work-up of a liver mass in the setting of elevated AFP or liver function impairment, especially in the absence of chronic liver disease.

Omega loop gastric bypass is a successful bariatric surgery with numerous favorable circumstances as being basic, effective on weight reduction and treatment of obesity associated metabolic disorder, the short expectation to learn and adapt, and the simplicity of correction and inversion. However, there are arguments about the possibility of biliary reflux and/or the potential danger of gastroesophageal malignancy after the procedure. Fifty patients experiencing morbid obesity with body mass index >40 or >35 kg/m 2 with two related comorbidities, for example, diabetes type II, hypertension, or dyslipidemia, underwent omega loop gastric bypass with a follow-up period up to 18 months, investigating for any symptom of reflux infection by upper gastrointestinal tract endoscopy and pH metry. Reflux esophagitis (a gastroesophageal reflux disease) was detected in 3 patients (6%); 2 cases (4%) showed (Grade A) acidic reflux esophagitis at 6 and 12 months postoperatively. Just 1 case (2%) had experienced gastroesophageal biliary reflux esophagitis (Grade A) at 12 months. No metaplasia or dysplasia was detected in the endoscopic biopsies. Omega loop gastric bypass is a safe and effective bariatric procedure with low incidence of postoperative biliary reflux, metaplasia, or dysplasia at the esophagogastric junction, confirmed 18 months after the operation.

Results from studies conducted in the late 1980s and early 1990 s showed that gastrointestinal symptoms were common among the general population. Meanwhile, lifestyle habits have changed and important treatment options have been introduced. This might have influenced symptom prevalence. This study aimed to describe the current prevalence of upper and lower gastrointestinal symptoms within the general population. For this purpose, a demographically representative sample of the Dutch population within the city of Nijmegen and surrounding areas was selected after careful comparison with demographic figures from a government demographic database. Participants were invited to fill in a valid self-report questionnaire about gastrointestinal symptoms and prevalence figures were calculated. A total of 5000 questionnaires was sent and 1616 (32%) were returned. Of these, 839 (52%) subjects reported having had upper (43%) or lower (38%) gastrointestinal symptoms in the past four weeks. The most prevalent individual symptoms reported were flatulence (47%), abdominal rumbling (40%), bloating (37%), alternating solid and loose stools (31%), belching (25%) and postprandial fullness (25%). People who smoked or used a proton pump inhibitor had an increased risk for reporting upper as well as lower gastrointestinal symptoms (OR 1.99; 95% CI 1.56 to 2.55, and OR 1.37; 95% CI 1.01 to 1.75, respectively for smoking; and OR 3.17; 95% CI 2.17 to 4.72, and OR 2.14; 95% CI 1.49 to 3.08, respectively for PPIs). Both upper and lower gastrointestinal symptoms are very common in a representative sample of a general Western population.

We report a case of a 56-year-old woman with a history of allogenic bone marrow transplantation for two years, complaining with dysphagia and weight loss. Upper endoscopy revealed esophageal stenosis and extensive mucosa sloughing. Biopsies confirmed the diagnosis of graft-vs-host disease (GVHD). Balloon dilation, corticosteroids and cyclosporin resulted in marked clinical improvement. Gastrointestinal tract is involved in the majority of patients with chronic GVHD. Esophageal manifestations are rare and include vesiculobullous disease, ulceration, esophageal webs, casts or strictures. Sloughing esophagitis along with severe stenosis requiring endoscopic dilation has never been reported in this context.

High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-line therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safely during pregnancy or for patients wishing to conceive, with the exception that male patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation.

HAART toxicity masquerading as a surgical abdomen

2015-01-01

Introduction Intussusception is a rare disease in adults and poses a challenge to identify and manage. In adults, surgical resection is the preferred treatment since half are due to malignancy. This case reveals an association between highly active antiretroviral therapy (HAART) and intussusception. Presentation of case A 44 year-old female with history of HIV on highly active antiretroviral therapy (HAART) presented with 3 month history of epigastric pain, nausea, emesis, weight loss, and lactic acidosis. CT of abdomen showed two small bowel intussusceptions and pericolic fat infiltration. A diagnosis of mitochondrial toxicity secondary to HAART medication was made. HAART medication was discontinued with resolution of symptoms. Further work-up to exclude a mechanical cause for her symptoms including colonoscopy, small bowel follow through, esophagogastroduodenoscopy, and repeat CT were performed. All established an absence of malignancy and intussusception. Discussion Mitochondrial toxicity (MT) is a well-known complication of HAART. A hallmark of MT is lactic acidosis which when untreated can be fatal. Although MT is known to cause gastrointestinal symptoms, intussusception has not been previously reported. In our patient with MT, prolonged usage of HAART medication resulted in severe gastrointestinal symptoms and intussusception mimicking a surgical abdomen. Laparotomy has been recommended on adult patients with intussusceptions because of the high likelihood of identifying a pathologic lesion. The doctrine of adult intussusception is to operate for concern of malignancy. Conclusion Surgeons, gastroenterologist and internist caring for patients on HAART therapy must be aware of the possibility of MT when evaluating HIV patients for possible surgical abdomen.

Inflammatory bowel disease (IBD) is a devastating immune-mediated disease on the rise in Hispanics living in the USA. Prior observational studies comparing IBD characteristics between Hispanics and non-Hispanic whites (NHW) have yielded mixed results. We performed a meta-analysis of observational studies examining IBD phenotype in Hispanics compared to NHW. We conducted a systematic search of US-based studies comparing IBD subtype (Ulcerative Colitis: UC or Crohn's disease: CD) and phenotype (disease location and behavior) between Hispanics and NHW. We evaluated differences in age at IBD diagnosis, the presence of family history and smoking history. A random effects model was chosen "a priori." Categorical and continuous variables were analyzed using odds ratio (OR) or standard mean difference (SMD), respectively. Seven studies were included with 687 Hispanics and 1586 NHW. UC was more common in Hispanics compared to NHW (OR 2.07, CI 1.13-3.79, p = 0.02). Location of disease was similar between Hispanics and NHW except for the presence of upper gastrointestinal CD, which was less common in Hispanics (OR 0.58, CI 0.32-1.06, p = 0.07). Hispanics were less likely to smoke (OR 0.48, CI 0.26-0.89, p = 0.02) or have a family history of IBD (OR 0.35, CI 0.22-0.55, p < 0.001). CD behavior classified by Montreal classification and age at IBD diagnosis were similar between Hispanics and NHW. UC was more common among US Hispanics compared to NHW. Age at IBD diagnosis is similar for both Hispanics and NHW. For CD, disease behavior is similar, but Hispanics show a trend for less upper gastrointestinal involvement. A family history of IBD and smoking history were less common in Hispanics.

Acute nonvariceal upper gastrointestinal bleeding remains an important cause of hospital admission with an associated mortality of 2-14%. Initial patient evaluation includes rapid hemodynamic assessment, large-bore intravenous catheter insertion and volume resuscitation. A hemoglobin transfusion threshold of 7 g/dL is recommended, and packed red blood cell transfusion may be necessary to restore intravascular volume and improve tissue perfusion. Patients should be risk stratified into low- and high-risk categories, using validated prognostic scoring systems such as the Glasgow-Blatchford, AIMS65 or Rockall scores. Effective early management of acute, nonvariceal upper gastrointestinal hemorrhage is critical for improving patient outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

Acute on chronic gastrointestinal bleeding: a unique clinical entity.

Gastrointestinal bleeding is defined in temporal-spatial terms-as acute or chronic, and/or by its location in the gastrointestinal tract. Here, we define a distinct type of bleeding, which we have coined 'acute on chronic' gastrointestinal bleeding. We prospectively identified all patients who underwent endoscopic evaluation for any form of gastrointestinal bleeding at a University Hospital. Acute on chronic bleeding was defined as the presence of new symptoms or signs of acute bleeding in the setting of chronic bleeding, documented as iron deficiency anemia. Bleeding lesions were categorized using previously established criteria. We identified a total of 776, 254, and 430 patients with acute, chronic, or acute on chronic bleeding, respectively. In patients with acute on chronic gastrointestinal bleeding, lesions were most commonly identified in esophagus (28%), colon and rectum (27%), and stomach (21%) (p<0.0001 vs locations for acute or chronic bleeding). In those specifically with acute on chronic upper gastrointestinal bleeding (n=260), bleeding was most commonly due to portal hypertensive lesions, identified in 47% of subjects compared with 29% of acute and 25% of chronic bleeders, (p<0.001). In all patients with acute on chronic bleeding, 30-day mortality was less than that after acute bleeding alone (2% (10/430) vs 7% (54/776), respectively, p<0.001). Acute on chronic gastrointestinal bleeding is common, and in patients with upper gastrointestinal bleeding was most often a result of portal hypertensive upper gastrointestinal tract pathology. Reduced mortality in patients with acute on chronic gastrointestinal bleeding compared with those with acute bleeding raises the possibility of an adaptive response.

Stem cells in gastroenterology and hepatology

Cellular and tissue regeneration in the gastrointestinal tract and liver depends on stem cells with properties of longevity, self-renewal and multipotency. Progress in stem cell research and the identification of potential esophageal, gastric, intestinal, colonic, hepatic and pancreatic stem cells provides hope for the use of stem cells in regenerative medicine and treatments for disease. Embryonic stem cells and induced pluripotent stem cells have the potential to give rise to any cell type in the human body, but their therapeutic application remains challenging. The use of adult or tissue-restricted stem cells is emerging as another possible approach for the treatment of gastrointestinal diseases. The same self-renewal properties that allow stem cells to remain immortal and generate any tissue can occasionally make their proliferation difficult to control and make them susceptible to malignant transformation. This Review provides an overview of the different types of stem cell, focusing on tissue-restricted adult stem cells in the fields of gastroenterology and hepatology and summarizing the potential benefits and risks of using stems cells to treat gastroenterological and liver disorders.

The aim of this study was to investigate the relationship between gastrointestinal symptoms, nutritional balance, and performance status in patients receiving palliative care for advanced cancers originating in different sites. We studied a total of 105 patients. Upper gastrointestinal symptoms, Eastern Cooperative Oncology Group Performance Status score (ECOG-PS), dietary intakes, anthropometric measures, and some serum proteins were determined. Unintentional weight loss, alterations in anthropometric measures, and highest number of symptoms were greater in patients with lung and stomach cancer. No differences were found in ECOG-PS according to cancer site. Patients with gastric or lung cancer have most evidence of protein-calorie malnutrition and a higher prevalence of upper gastrointestinal symptoms. The performance status is not affected by tumor site. Early nutritional support should be planned for all patients with cancer, especially for patients with gastric or lung cancer.

[Effect of preoperative oral 5'-DFUR on PyNPase level in gastrointestinal malignant tumor tissues].

Pyrimidine nucleoside phosphorylase (PyNPase) exists mainly in tumor tissues.5'-deoxy-5-fluorouridine(5'-DFUR) can decrease its level in tumor tissues. However, the effect of preoperative oral 5'-DFUR on PyNPase level in the different time after administration has not been reported. This study was designed to investigate the suitable duration of preoperative chemotherapy through observing the changes of PyNPase levels in gastrointestinal malignant tumors after preoperative oral administration of 5'- DFUR in different duration. Seventy-three patients with gastrointestinal malignant tumors were divided into four groups by the duration of preoperative oral 5'-DFUR (600-1,200 mg x d(-1)): group A, three days, 27 cases; group B, one week, 22 cases; group C, two weeks, 15 cases; group D, two months, 9 cases. Meanwhile, group E, control group, had 24 inpatients with gastrointestinal malignant tumors at the same term. All the above-mentioned patients did not receive the other chemotherapy or radiotherapy. The changes of PyNPase levels in tumor tissues of different groups were tested using reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC), etc. (1)Under electron microscope, there were many irrecoverable, lethal changes in tumor cells of group C. The outlines of the tumor cells were normal under light microscope, and more fibroconnective tissues were seen only in the stroma of group D. (2)The expressing levels of PyNPase mRNA and protein production in tumor tissues reduced obviously in group A (0.79+/-0.08, 19.26+/-1.65), and decreased most obviously in group C (0.43+/-0.07,5.91+/-1.45) comparing with group E (0.95+/-0.09, 29.34+/-1.82). However, there was no significant difference between group C and group D (0.42+/-0.04, 5.36+/-1.19) for the levels of PyNPase mRNA and protein production. The correlation coefficient between the levels of PyNPase mRNA and protein in tumor tissues of different group was r=0.92(P< 0.0001). 5'-DFUR by oral administration before operation might destroy gastrointestinal malignant tumor cells. As the duration prolonged, the content of PyNPase in tumor tissues decreased progressively, being lowest level in two weeks after chemotherapy. So two-week duration might be suitable for the treatment.

Prevention of nonsteroidal anti-inflammatory drug-induced gastropathy.

2009-01-01

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for their analgesic, antipyretic, and antiinflammatory properties, and aspirin is increasingly employed in the primary and secondary prevention of cardiovascular disease and ischemic stroke. Despite undisputed therapeutic efficacy for these indications, all NSAIDs impart a considerable risk of peptic ulcer disease and upper gastrointestinal hemorrhage. A growing body of evidence supports an association between non-aspirin NSAIDs and acute coronary syndromes, and an expanding understanding of the gastroduodenal effects of aspirin, COX-2 selective agents, clopidogrel, and Helicobacter pylori synergism fuel controversies in NSAID use. In this review, we discuss risk stratification of patients taking NSAIDs and the appropriate application of proven gastro-protective strategies to decrease the incidence of gastrointestinal hemorrhage based upon an individualized assessment of risk for potential toxicities. Prevention of NSAID-related gastropathy is an important clinical issue, and therapeutic strategies for both the primary and secondary prevention of adverse events are continually evolving.

The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobin<100 g/l) with proved source of blood losses in upper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobin<100 g/l) significantly higher portions of patients are taking antiplatelet rather than anticoagulation therapy. This may be caused by greater use of these drugs in the population, but on the other hand it may reflect an association with greater risk of gastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even though they do not meet the indication for the prescription according to the guidelines.

In patients with acute nonvariceal upper gastrointestinal bleeding, rebleeding after an initial treatment is observed in 10-20% and is associated with mortality. To investigate whether the initial serum C-reactive protein level could predict the risk of rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding. This was a retrospective study using prospectively collected data for upper gastrointestinal bleeding. Initial clinical characteristics, endoscopic features, and C-reactive protein levels were compared between those with and without 30-day rebleeding. A total of 453 patients were included (mean age, 62 years; male, 70.9%). The incidence of 30-day rebleeding was 15.9%. The mean serum C-reactive protein level was significantly higher in these patients than in those without rebleeding (P<0.001). The area under the receiver operating characteristics curve with a cutoff value of 0.5mg/dL was 0.689 (P<0.001). High serum C-reactive protein level (odds ratio, 2.98; confidence interval, 1.65-5.40) was independently associated with the 30-day rebleeding risk after adjustment for the main confounding risk factors, including age, blood pressure, and initial haemoglobin level. The serum C-reactive protein was an independent risk factor for 30-day rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding, indicating a possible role as a useful screening indicator for predicting the risk of rebleeding.

Selecting patients with an urgent need for endoscopic hemostasis is difficult based only on simple parameters of presumed acute upper gastrointestinal bleeding. This study assessed easily applicable factors to predict cases in need of urgent endoscopic hemostasis due to acute upper gastrointestinal bleeding. The consecutively included patients were divided into the endoscopic hemostasis and nonendoscopic hemostasis groups. We reviewed the enrolled patients' medical records and analyzed various variables and parameters for acute upper gastrointestinal bleeding outcomes such as demographic factors, comorbidities, symptoms, signs, laboratory findings, rebleeding rate, and mortality to evaluate simple predictive factors for endoscopic treatment. A total of 613 patients were analyzed, including 329 patients in the endoscopic hemostasis and 284 patients in the non-endoscopic hemostasis groups. In the multivariate analysis, a bloody nasogastric lavage (adjusted odds ratio [AOR], 6.786; 95% confidence interval [CI], 3.990 to 11.543; p < 0.0001) and a hemoglobin level less than 8.6 g/dL (AOR, 1.768; 95% CI, 1.028 to 3.039; p = 0.039) were independent predictors for endoscopic hemostasis. Significant differences in the morbidity rates of endoscopic hemostasis were detected between the group with no predictive factors and the group with one or more predictive factors (OR, 2.677; 95% CI, 1.920 to 3.733; p < 0.0001). A bloody nasogastric lavage and hemoglobin < 8.6 g/dL were independent predictors of endoscopic hemostasis in patients with acute upper gastrointestinal bleeding.

Few studies with contradictory results have been published on the safety of pelvic radiation therapy (RT) in patients with inflammatory bowel disease (IBD). From 1989 to 2015, a single center retrospective analysis was performed including all IBD patients who received pelvic external beam radiation therapy (EBRT) or brachytherapy (BT) for a pelvic malignancy. Treatment characteristics, IBD activity and gastrointestinal (GI) toxicity were examined. Overall, 28 patients with Crohn's disease (CD) (n=13) or ulcerative colitis (n=15) were included in the present study. Median follow-up time after irradiation was 5.9 years. Regarding IBD activity, only one and two patients experienced a severe episode within and after 6 months of follow-up, respectively. Grade 3/4 acute GI toxicity occurred in 3 (11%) patients, whereas one (3.6%) patient experienced late grade 3/4 GI toxicity. Only patients with rectal IBD location (P=0.016) or low body mass index (BMI) (P=0.012) experienced more severe IBD activity within or after 6 months following RT, respectively. We report an acceptable tolerance of RT in IBD patients with pelvic malignancies. Specifically, a low risk of uncontrolled flare-up was observed.

The increase in the routine use of abdominal imaging has led to a parallel surge in the identification of polypoid lesions in the gallbladder. True gallbladder polyps (GBP) have malignant potential and surgery can prevent or treat early gallbladder cancer. In an era of constraint on health care resources, it is important to ensure that surgery is offered only to patients who have appropriate indications. The aim of this study was to assess treatment and surveillance policies for GBP among hepatobiliary and upper gastrointestinal tract surgeons in the UK in the light of published evidence. A questionnaire on the management of GBP was devised and sent to consultant surgeon members of the Association of Upper Gastrointestinal Surgeons (AUGIS) of Great Britain and Ireland with the approval of the AUGIS Committee. It included eight questions on indications for laparoscopic cholecystectomy and surveillance based on GBP (size, number, growth rate) and patient (age, comorbidities, ethnicity) characteristics. A total of 79 completed questionnaires were returned. The vast majority of surgeons (>75%) stated that they would perform surgery when a single GBP reached 10 mm in size. However, there was a lack of uniformity in the management of multiple polyps and polyp growth rate, with different surveillance protocols for patients treated conservatively. Gallbladder polyps are a relatively common finding on abdominal ultrasound scans. The survey showed considerable heterogeneity among surgeons regarding treatment and surveillance protocols. Although no randomized controlled trials exist, national guidelines would facilitate standardization, the formulation of an appropriate algorithm and appropriate use of resources. © 2012 International Hepato-Pancreato-Biliary Association.

Functional imaging gives information about physiological heterogeneity in tumours. The utility of functional imaging tests in providing predictive and prognostic information after chemoradiotherapy for both oesophageal cancer and pancreatic cancer will be reviewed. The benefit of incorporating functional imaging into radiotherapy planning is also evaluated. In cancers of the upper gastrointestinal tract, the vast majority of functional imaging studies have used (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET). Few studies in locally advanced pancreatic cancer have investigated the utility of functional imaging in risk-stratifying patients or aiding target volume definition. Certain themes from the oesophageal data emerge, including the need for a multiparametric assessment of functional images and the added value of response assessment rather than relying on single time point measures. The sensitivity and specificity of FDG-PET to predict treatment response and survival are not currently high enough to inform treatment decisions. This suggests that a multimodal, multiparametric approach may be required. FDG-PET improves target volume definition in oesophageal cancer by improving the accuracy of tumour length definition and by improving the nodal staging of patients. The ideal functional imaging test would accurately identify patients who are unlikely to achieve a pathological complete response after chemoradiotherapy and would aid the delineation of a biological target volume that could be used for treatment intensification. The current limitations of published studies prevent integrating imaging-derived parameters into decision making on an individual patient basis. These limitations should inform future trial design in oesophageal and pancreatic cancers. Copyright © 2014 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

The purpose of this study was to identify endoscopic and clinical parameters influencing the decision-making in salvage of endoscopically unmanageable, nonvariceal upper gastrointestinal hemorrhage (UGIH) and to report the outcome of selected therapy. We retrospectively retrieved all cases of surgery and arteriography for arrest of endoscopically unmanageable UGIH. Only patients with overt bleeding on endoscopy within the previous 24 h were included. Patients with preceding nonendoscopic hemostatic interventions, portal hypertension, malignancy, and transpapillar bleeding were excluded. Potential clinical and endoscopic predictors of allocation to either surgery or arteriography were tested using statistical models. Outcome and survival were regressed on themore » choice of rescue and clinical variables. Forty-six arteriographed and 51 operated patients met the inclusion criteria. Univariate analysis revealed a higher number of patients with a coagulation disorder in the catheterization group (41.4%, versus 20.4% in the laparotomy group; p = 0.044). With multivariate analysis, the identification of a bleeding peptic ulcer at endoscopy significantly steered decision-making toward surgical rescue (OR = 5.2; p = 0.021). Taking into account reinterventions, hemostasis was achieved in nearly 90% of cases in both groups. Overall therapy failure (no survivors), rebleeding within 3 days (OR = 3.7; p = 0.042), and corticosteroid use (OR = 5.2; p = 0.017) had a significant negative impact on survival. The odds of dying were not different for embolotherapy or surgery. In conclusion, decision-making was endoscopy-based, with bleeding peptic ulcer significantly directing the choice of rescue toward surgery. Unsuccessful hemostasis and corticosteroid use, but not the choice of rescue, negatively affected outcome.« less

Amplification of proto-oncogenes associated with their over-expression is one of the critical carcinogenic events identified in human cancer cells. In many cases of human gastric cancer, a proto-oncogene ERBB-2 is co-amplified with CAB1 genes physically linked to ERBB-2, and both genes are over-expressed. The amplified region containing ERBB-2 and CAB1 was named 17q12 amplicon from its chromosomal location. The syntenic region corresponding to the 17q12 amplicon is well conserved in mouse. In this study we isolated and characterized a novel mouse gene that locates telomeric to the mouse syntenic region. Northern blot analysis using the mouse cDNA and a cloned partial cDNA of human homolog disclosed a unique expression pattern of the genes. They are expressed predominantly in the gastrointestinal (GI) tract and in the skin at a lower level. Moreover, in the GI tract, the expression is highly restricted to the esophagus and stomach. Thus, we named the mouse gene Gasdermin (Gsdm). This is the first report of a mammalian gene whose expression is restricted to both upper GI tract and skin. Interestingly, in spite of its expression in normal stomach, no transcript was detected by Northern blot analysis in human gastric cancer cells. These data suggest that the loss of the expression of the human homolog is required for the carcinogenesis of gastric tissue and that the gene has an activity adverse to malignant transformation of cells.

Raman spectroscopy is a vibrational analytic technique sensitive to the changes in biomolecular composition and conformations occurring in tissue. With our most recent development of near-infrared (NIR) Raman endoscopy integrated with diagnostic algorithms, in vivo real-time Raman diagnostics has been realized under multimodal wide-field imaging (i.e., white- light reflectance (WLR), narrow-band imaging (NBI), autofluorescence imaging (AFI)) modalities. A selection of 177 patients who previously underwent Raman endoscopy (n=2510 spectra) was used to render two robust models based on partial least squares - discriminant analysis (PLS-DA) for esophageal and gastric cancer diagnosis. The Raman endoscopy technique was validated prospectively on 4 new gastric and esophageal patients for in vivo tissue diagnosis. The Raman endoscopic technique could identify esophageal cancer in vivo with a sensitivity of 88.9% (8/9) and specificity of 100.0% (11/11) and gastric cancers with a sensitivity of 77.8% (14/18) and specificity of 100.0% (13/13). This study realizes for the first time the image-guided Raman endoscopy for real-time in vivo diagnosis of malignancies in the esophagus and gastric at the biomolecular level.

OBJECTIVES Previous studies of vitamin D status in pediatric patients with inflammatory bowel disease have revealed conflicting results. We sought to report (1) the prevalence of vitamin D deficiency (serum 25-hydroxy-vitamin D concentration ≤15 ng/mL) in a large population with inflammatory bowel disease, (2) factors predisposing to this problem, and (3) its relationship to bone health and serum parathyroid hormone concentration. PATIENTS AND METHODS A total of 130 patients (8–22 years of age) with inflammatory bowel disease, 94 with Crohn disease and 36 with ulcerative colitis, had serum 25-hydroxy-vitamin D, intact parathyroid hormone, and lumbar spine bone mineral density (using dual-energy x-ray absorptiometry) measured at Children’s Hospital Boston. RESULTS The prevalence of vitamin D deficiency was 34.6%. Mean serum 25-hydroxy-vitamin D concentration was similar in patients with Crohn disease and ulcerative colitis, 52.6% lower among patients with dark skin complexion, 33.4% lower during the winter months (December 22 to March 21), and 31.5% higher among patients who were taking vitamin D supplements. Serum 25-hydroxy-vitamin D concentration was positively correlated with weight and BMI z score, disease duration, and serum albumin concentration and negatively correlated with erythrocyte sedimentation rate. Patients with Crohn disease and upper gastrointestinal tract involvement were more likely to be vitamin D deficient than those without it. Serum 25-hydroxy-vitamin concentration was not associated with lumbar spine bone mineral density z score or serum parathyroid hormone concentration. CONCLUSIONS Vitamin D deficiency is highly prevalent among pediatric patients with inflammatory bowel disease. Factors predisposing to the problem include having a dark-skin complexion, winter season, lack of vitamin D supplementation, early stage of disease, more severe disease, and upper gastrointestinal tract involvement in patients with Crohn disease. The long-term significance of hypovitaminosis D for this population is unknown at present and merits additional study. PMID:17079566

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE), endorsed by the European Society for Radiotherapy and Oncology (ESTRO), the European Society of Digestive Endoscopy (ESDO), and the European Society for Clinical Nutrition and Metabolism (ESPEN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations for malignant disease 1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliative treatment of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass (strong recommendation, high quality evidence). 2 For patients with longer life expectancy, ESGE recommends brachytherapy as a valid alternative or in addition to stenting in esophageal cancer patients with malignant dysphagia. Brachytherapy may provide a survival advantage and possibly a better quality of life compared to SEMS placement alone. (Strong recommendation, high quality evidence.) 3 ESGE recommends esophageal SEMS placement as the preferred treatment for sealing malignant tracheoesophageal or bronchoesophageal fistula (strong recommendation, low quality evidence). 4 ESGE does not recommend the use of concurrent external radiotherapy and esophageal stent treatment. SEMS placement is also not recommended as a bridge to surgery or prior to preoperative chemoradiotherapy. It is associated with a high incidence of adverse events and alternative satisfactory options such as placement of a feeding tube are available. (Strong recommendation, low quality evidence.) Main recommendations for benign disease 1 ESGE recommends against the use of self-expandable stents (SEMSs) as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and costs (strong recommendation, low quality evidence). 2 ESGE suggests consideration of temporary placement of SEMSs as therapy for refractory benign esophageal strictures (weak recommendation, moderate evidence). Stents should usually be removed at a maximum of 3 months (strong recommendation, weak quality evidence). 3 ESGE suggests that fully covered SEMSs be preferred over partially covered SEMSs for the treatment of refractory benign esophageal strictures, because of their lack of embedment and ease of removability (weak recommendation, low quality evidence). 4 For the removal of partially covered esophageal SEMSs that are embedded, ESGE recommends the stent-in-stent technique (strong recommendation, low quality evidence). 5 ESGE recommends that temporary stent placement can be considered for treating esophageal leaks, fistulas, and perforations. The optimal stenting duration remains unclear and should be individualized. (Strong recommendation, low quality evidence.) 6 ESGE recommends placement of a SEMS for the treatment of esophageal variceal bleeding refractory to medical, endoscopic, and/or radiological therapy, or as initial therapy for patients with massive esophageal variceal bleeding (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Peutz-Jeghers syndrome: Diagnostic and therapeutic approach

Peutz-Jeghers syndrome (PJS) is an inherited, autosomal dominant disorder distinguished by hamartomatous polyps in the gastrointestinal tract and pigmented mucocutaneous lesions. Prevalence of PJS is estimated from 1 in 8300 to 1 in 280 000 individuals. PJS predisposes sufferers to various malignancies (gastrointestinal, pancreatic, lung, breast, uterine, ovarian and testicular tumors). Bleeding, obstruction and intussusception are common complications in patients with PJS. Double balloon enteroscopy (DBE) allows examination and treatment of the small bowel. Polypectomy using DBE may obviate the need for repeated urgent operations and small bowel resection that leads to short bowel syndrome. Prophylaxis and polypectomy of the entire small bowel is the gold standard in PJS patients. Intraoperative enteroscopy (IOE) was the only possibility for endoscopic treatment of patients with PJS before the DBE era. Both DBE and IOE facilitate exploration and treatment of the small intestine. DBE is less invasive and more convenient for the patient. Both procedures are generally safe and useful. An overall recommendation for PJS patients includes not only gastrointestinal multiple polyp resolution, but also regular lifelong cancer screening (colonoscopy, upper endoscopy, computed tomography, magnetic resonance imaging or ultrasound of the pancreas, chest X-ray, mammography and pelvic examination with ultrasound in women, and testicular examination in men). Although the incidence of PJS is low, it is important for clinicians to recognize these disorders to prevent morbidity and mortality in these patients, and to perform presymptomatic testing in the first-degree relatives of PJS patients.

To evaluate current clinical practice for octogenarians with iron-deficiency anemia (IDA) by assessing referral patterns, diagnostic choices, clinical consequences of omission of endoscopy, and risks and benefits of IDA-related surgery. Chart review. A regional hospital-based laboratory in the Netherlands between January 2008 and December 2010. All individuals aged 80 and older with newly ascertained IDA. IDA was defined as a hemoglobin level of 11.1 g/dL or less and a ferritin level of 25 μg/L or less. Four hundred seventy-one participants were newly diagnosed with IDA during the study period (median age 85.4), 276 of whom (59%) did not undergo any diagnostic procedures for IDA. A cause of anemia was identified during the initial examination in 50% of the 205 investigated participants, including nine (4%) upper and 37 (18%) lower gastrointestinal malignancies. Another 24 malignancies were identified during follow-up, of which 16 were in the gastrointestinal tract, primarily in participants for whom the initial diagnostic examination was limited or omitted. Perioperative mortality was 15% in individuals with colon cancer. Median survival for participants with colon cancer was 2.2 years, and the survival benefit of surgery over supportive care was not apparent until 1.3 years after ascertainment of IDA. The omission of endoscopy for IDA and the omission of surgery for colon cancer occur frequently in octogenarians and seem appropriate in the presence of significant comorbidity and in cases in which there is limited life expectancy. Further research is needed to determine which baseline factors should guide decision-making to optimize treatment outcomes and quality of life. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

To describe a case of extranodal marginal zone B-cell lymphoma (EMZL) "mucosa associated lymphoid tissue (MALT)" of the orbit that presented with stage IV disease in a patient with sarcoidosis. Clinicopathologic case report. Biopsies of the lesion were performed in the operating room and the samples were submitted for pathology processing. Pathology analysis identified the lesion as an extranodal marginal zone B-cell lymphoma "mucosa associated lymphoid tissue (MALT)" via flow cytometry, histopathology, cytogenetics, and immunohistochemical staining and fluorescent in situ hybridization (FISH). The institutional review board of Howard University Hospital waived the need for IRB approval for this intraoperative finding. A 70-year-old Black woman with biopsy-proven sarcoidosis presented complaining of foreign body sensation, redness, swelling of her left upper eyelid and tearing. The patient was found to have an orbital lymphoproliferative malignancy. It is still unclear if the presence of immunosuppression or an autoimmune disease increases the risk of lymphoproliferative malignancies {6}. Malignancy should always be suspected and investigated.

Bleeding from a pancreatic pseudocyst is a severe complication after pancreatitis that can lead to a massive gastrointestinal blood loss. Pseudocyst rupture into the stomach is an unusual complication. We report the case of a 34-year-old woman with a history of alcoholism and a pancreatic pseudocyst. One year after follow-up of her pseudocyst, she arrived at the emergency room with an episode of upper gastrointestinal bleeding. An upper digestive endoscopy showed active bleeding in the subcardial fundus, which could not be endoscopically controlled. Abdominal angio-CT confirmed the diagnosis of a splenic artery pseudoaneurysm in close contact with the back wall of the stomach, as well as a likely fistulization of it. The patient was urgently operated and a distal splenopancreatectomy and fistulorrhaphy was performed. The rupture of a splenic artery pseudoaneurysm may rarely present as upper gastrointestinal bleeding. This may be lethal if not urgently treated.

Jaundice is a yellowish pigmentation of skin and mucous membranes caused by hyperbilirubinemia, which itself has various causes. Jaundice related to malignant tumors is classified as obstructive jaundice. This disease proceeds from biliary tract obstruction and liver failure by progression of intrahepatic tumors, including metastases from other malignancies. Biliary tract cancer, pancreatic head cancer, or lymph nodes metastases from other sites of cancer are mainly responsible for the obstruction of the bile duct. In patients with obstructive jaundice, biliary drainage is often required in order to give treatments such as chemotherapy. In patients with biliary drainage, various complications arise, such as cholangitis due to obstruction ofa biliary stent, and bleeding from the ulcer due to a dislodged stent to the duodenum. It is crucial to manage those complications as oncologic emergencies. Jaundice of liver failure due to hepatic metastases is often observed in patients with gastrointestinal malignancies such as gastric cancer or colorectal cancer. Although chemotherapy is the usual application for those patients, useful anti-cancer agents are limited. It is crucial to diagnose and decide the best treatments as soon as possible for patients with very advanced hepatic metastases.

Despite the establishment of effective medical therapies in peptic ulcer disease, gastric outlet obstruction remains one of the most common health problem in Tunisia. Various operations have been attempted, which may lead to postoperative morbidity. Gastrointestinal (GI) motility dysfunction is the most common complications. to determine the predictive factor of gastrointestinal motility dysfunction after gastrojejunostomy for peptic ulcer stenosis. We carried out a retrospective study to evaluate the postoperative recovery of the motility of the upper gastrointestinal tract after gastrojejunostomy for peptic ulcer stenosis. During the 9- year study, 138 patients underwent operations for ulcer peptic stenosis. Among the patients, 116 (84,1%) were treated with gastrojejunostomy. Descriptive statistics, univariate and multivariate analyses were performed. The mean age of patients was 47.85 years (range: 19- 92years) and most. Were male (84, 5 %). Ninety two (79.3%) patients had a documented history of peptic ulcer disease. The duration of symptoms ranged from 10 to 372 days (mean: 135.86 days). Eighty two (71%) patients were operated on through laparotomy. Laparoscopic procedure was performed in 29% of the patients. There was no operative mortality. Perioperative morbidity occurred in 12.4% (14 patients). Gastrointestinal motility dysfunction occurred in 12 patients (10.3%). It was treated by nasogastric aspiration and prokinetics. By univariate analysis; diabetes (0,010), cachexia (0,049), ASA class (0.05) were all statistically associated with gastrointestinal motility dysfunction in this series. Multivariate logistic regression analysis (table 2) showed that the cachexia (0,009), ASA class (0.02) were the main predictors of gastrointestinal motility dysfunction after gastrojejunostomy for peptic ulcer stenosis in the followed patients. Gastrointestinal motility dysfunction is the most common complications after gastrojejunostomy for pyloric adult stenosis. Surgery must be preceded by careful medical preparation. It is more likely to occur in patients with an ASA class 2 or greater. Those patients should be considered for other treatment options, such as endoscopic balloon dilation.

Flushing is the subjective sensation of warmth accompanied by visible cutaneous erythema occurring throughout the body with a predilection for the face, neck, pinnae, and upper trunk where the skin is thinnest and cutaneous vessels are superficially located and in greatest numbers. Flushing can be present in either a wet or dry form depending upon whether neural-mediated mechanisms are involved. Activation of the sympathetic nervous system results in wet flushing, accompanied by diaphoresis, due to concomitant stimulation of eccrine sweat glands. Wet flushing is caused by certain medications, panic disorder and paroxysmal extreme pain disorder (PEPD). Vasodilator mediated flushing due to the formation and release of a variety of biogenic amines, neuropeptides and phospholipid mediators such as histamine, serotonin and prostaglandins respectively, typically presents as dry flushing where sweating is characteristically absent. Flushing occurring with neuroendocrine tumors accompanied by gastrointestinal symptoms is generally of the dry flushing variant, which may be an important clinical clue to the differential diagnosis. A number of primary diseases of the gastrointestinal tract cause flushing, and conversely extra-intestinal conditions are associated with flushing and gastrointestinal symptoms. Gastrointestinal findings vary and include one or more of the following non-specific symptoms such as abdominal pain, nausea, vomiting, diarrhea or constipation. The purpose of this review is to provide a focused comprehensive discussion on the presentation, pathophysiology, diagnostic evaluation and management of those diseases that arise from the gastrointestinal tract or other site that may cause gastrointestinal symptoms secondarily accompanied by flushing.

Background: Previous studies suggested a relationship between aspirin use and mortality reduction. The mechanism for the effect of aspirin on cancer outcomes remains unclear. The aim of this study was to evaluate aspirin use and survival in patients with gastrointestinal tract cancer. Methods: Patients with gastrointestinal tract cancer diagnosed between 1998 and 2011 were included. The population-based Eindhoven Cancer Registry was linked to drug-dispensing data from the PHARMO Database Network. The association between aspirin use after diagnosis and overall survival was analysed using Cox regression models. Results: In total, 13 715 patients were diagnosed with gastrointestinal cancer. A total of 1008 patients were identified as aspirin users, and 8278 patients were identified as nonusers. The adjusted hazard ratio for aspirin users vs nonusers was 0.52 (95% CI 0.44–0.63). A significant association between aspirin use and survival was observed for patients with oesophageal, hepatobiliary and colorectal cancer. Conclusions: Post-diagnosis use of aspirin in patients with gastrointestinal tract malignancies is associated with increased survival in cancers with different sites of origin and biology. This adds weight to the hypothesis that the anti-cancer effects of aspirin are not tumour-site specific and may be modulated through the tumour micro-environment. PMID:28072768

Lynch syndrome and chronic inflammatory bowel disease are two important risk factors for colorectal cancer. It is unclear whether Lynch syndrome patients with inflammatory bowel disease are at sufficiently increased risk for colorectal cancer to warrant prophylactic colectomy. This study aims to identify all cases of Lynch syndrome and concurrent inflammatory bowel disease in a large familial gastrointestinal cancer registry, define incidence of colorectal cancer, and characterize mismatch repair protein gene mutation status and inflammatory bowel disease-associated colorectal cancer risk factors. We retrospectively identified and collected clinical data for all cases with confirmed diagnoses of Lynch syndrome and inflammatory bowel disease in the Familial Gastrointestinal Cancer Registry at Mount Sinai Hospital in Toronto, Canada. Twelve cases of confirmed Lynch syndrome, and concurrent inflammatory bowel disease were identified. Four cases developed colorectal cancer. An additional five cases had colectomy; one was performed for severe colitis, and four were performed for low-grade dysplasia. None of these surgical specimens contained malignancy or high-grade dysplasia. The presentation of Lynch syndrome with inflammatory bowel disease is uncommon and not well described in the literature. This small but important series of twelve cases is the largest reported to date. In this series, patients with Lynch syndrome and concurrent inflammatory bowel disease do not appear to have sufficiently increased risk for colorectal cancer to recommend prophylactic surgery. Therefore, the decision to surgery should continue to be guided by surgical indications for each disease. Further evaluation of this important area will require multi-institutional input.

OBJECTIVES: The authors compared the safety, gastrointestinal tolerance, and clinical efficacy of feeding an enteral diet containing a fish oil/medium-chain triglyceride structured lipid (FOSL-HN) versus an isonitrogenous, isocaloric formula (O-HN) in patients undergoing major abdominal surgery for upper gastrointestinal malignancies. SUMMARY BACKGROUND DATA: Previous studies suggest that feeding with n-3 fatty acids from fish oil can alter eicosanoid and cytokine production, yielding an improved immunocompetence and a reduced inflammatory response to injury. The use of n-3 fatty acids as a structured lipid can improve long-chain fatty acid absorption. METHODS: This prospective, blinded, randomized trial was conducted in 50 adult patients who were jejunally fed either FOSL-HN or O-HN for 7 days. Serum chemistries, hematology, urinalysis, gastrointestinal complications, liver and renal function, plasma and erythrocyte fatty acid analysis, urinary prostaglandins, and outcome parameters were measured at baseline and on day 7. Comparisons were made in 18 and 17 evaluable patients based a priori on the ability to reach a tube feeding rate of 40 mL/hour. RESULTS: Patients receiving FOSL-HN experienced no untoward side effects, significant incorporation of eicosapentaenoic acid into plasma and erythrocyte phospholipids, and a 50% decline in the total number of gastrointestinal complications and infections compared with patients given O-HN. The data strongly suggest improved liver and renal function during the postoperative period in the FOSL-HN group. CONCLUSION: Early enteral feeding with FOSL-HN was safe and well tolerated. Results suggest that the use of such a formula during the postoperative period may reduce the number of infections and gastrointestinal complications per patient, as well as improve renal and liver function through modulation of urinary prostaglandin levels. Additional clinical trials to fully quantify clinical benefits and optimize nutritional support with FOSL-HN should be undertaken. Images Figure 1. Figure 2. Figure 3. PMID:8604913

Endoscopic stenting is increasingly being used in the management of gastrointestinal luminal obstruction, and has become the current treatment of choice for the palliation of blockage caused by malignant or benign growths. A variety of stents have been developed to enhance the efficacy of the procedure, and improvements are ongoing. In this article, we review the history of, and recent advances in, gastrointestinal stenting. We describe the rationale behind the design as well as the resulting outcome for each stent type.

Background and study aims  Self-expandable metallic stents (SEMS) have been increasingly used in benign conditions (e. g. strictures, fistulas, leaks, and perforations). Fully covered SEMS (FSEMS) were introduced to avoid undesirable consequences of partially covered SEMS (PSEMS), but come with higher risk of stent migration. Endoscopic suturing (ES) for stent fixation has been shown to reduce migration of FSEMS. Our aim was to compare the outcomes of FSEMS with ES (FS/ES) versus PSEMS in patients with benign upper gastrointestinal conditions. Patients and methods  We retrospectively identified all patients who underwent stent placement for benign gastrointestinal conditions at seven US tertiary-care centers. Patients were divided into two groups: FSEMS with ES (FS/ES group) and PSEMS (PSEMS group). Clinical outcomes between the two groups were compared. Results  A total of 74 (FS/ES 46, PSEMS 28) patients were included. On multivariable analysis, there was no significant difference in rate of stent migration between FS/ES (43 %) and PSEMS (15 %) (adjusted odds ratio 0.56; 95 % CI 0.15 – 2.00). Clinical success was similar [68 % vs. 64 %; P  = 0.81]. Rate of adverse events (AEs) was higher in PSEMS group [13 (46 %) vs. 10 (21 %); P  = 0.03). Difficult stent removal was higher in the PSEMS group (n = 5;17 %) vs. 0 % in the FS/ES group; P  = 0.005. Conclusions  The proportion of stent migration of FS/ES and PSEMS are similar. Rates of other stent-related AEs were higher in the PSEMS group. PSEMS was associated with tissue ingrowth or overgrowth leading to difficult stent removal, and secondary stricture formation. Thus, FSEMS with ES for stent fixation may be the preferred modality over PSEMS for the treatment of benign upper gastrointestinal conditions. PMID:29404384

Tuberculosis (TB) is an infectious disease that can affect any organ system of the body. Abdominal TB can be gastrointestinal, lymph nodal, visceral or peritoneal. The gallbladder (GB) is rarely involved in abdominal TB as a primary organ. Extensive research literature on gallbladder TB is limited to case reports. There has been no review on this rare abdominal pathology. GB tuberculosis is a difficult diagnosis preoperatively. It is a rare differential among the more common gallbladder pathologies such as cholelithiasis, or a gallbladder malignancy. Typical histopathology of the resected specimen helps to establish this rare diagnosis. Subjecting every specimen to histopathological examination followed by medical treatment offers the chance of cure. Through this review, the authors attempt to provide an insight into this disease entity.

The aim of this study was to identify the ability of Glasgow-Blatchford score (GBS) and pre-endoscopic Rockall score (pre-E RS) to predict the occurrence of hypotension in patients with non-variceal upper gastrointestinal bleeding who are initially normotensive at emergency department. Retrospective observational study was conducted at Asan Medical Center emergency department (ED) in patients who presented with non-variceal upper gastrointestinal bleeding from January 1, 2011 to December 31, 2013. Study population was divided according to the development of hypotension, and demographics, comorbidities, and laboratory findings were compared. GBS and pre-E RS were estimated to predict the occurrence of hypotension. A total of 747 patients with non-variceal upper gastrointestinal bleeding were included during the study period, and 120 (16.1%) patients developed hypotension within 24 hours after ED admission. The median values GBS and pre-E RS were statistically different according to the occurrence of hypotension (8.0 vs. 10.0, 2.0 vs. 3.0, respectively; p<0.001). In the receiver operating characteristic curve analysis of hypotension development, the area under the curve of GBS and pre-E RS were 66% and 64%, respectively. The sensitivity and the specificity of GBS using optimal cut-off value were 81% and 46%, respectively, while those based on the pre-E RS were 74% and 46%, respectively. GBS and pre-E RS were both not sufficient for predicting the occurrence of hypotension in non-variceal upper gastrointestinal bleeding. Development of other scoring systems are needed.

Prebiotics as functional food ingredients preventing diet-related diseases.

This paper reviews the potential of prebiotic-containing foods in the prevention or postponement of certain diet-related diseases, such as cardiovascular diseases with hypercholesterolemia, osteoporosis, diabetes, gastrointestinal infections and gut inflammation. Also the data on prebiotics as food ingredients and their impact on food product quality are presented. Prebiotics are short chain carbohydrates that are resistant to the digestion process in the upper part of the digestive system, are not absorbed in any segment of the gastrointestinal system, and finally are selectively fermented by specific genera of colonic bacteria. The mechanisms of the beneficial impacts of prebiotics on human health are very difficult to specify directly, because their health-promoting functions are related to fermentation by intestinal microflora. The impact of prebiotics on diet-related diseases in many ways also depends on the products of their fermentation. Prebiotics as functional food ingredients also have an impact on the quality of food products, due to their textural and gelling properties. Prebiotics as food additives can be very valuable in the creation of functional food aimed at preventing or postponing many diet-related diseases. They additionally have beneficial technological properties which improve the quality of food products.

To investigate the impact of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in association with a multidisciplinary team evaluation for the detection of gastrointestinal malignancies. A cohort of 1019 patients with suspected malignant lesions adjacent to the gastrointestinal tract received EUS-FNA after a standardized multidisciplinary team evaluation (MTE) and were divided into 4 groups according to their specific malignant risk score (MRS). Patients with a MRS of 0 (without detectable risk of malignancy) received only EUS without FNA. For patients with a MRS score ranging from 1 (low risk) - through 2 (intermediate risk) - to 3 (high risk), EUS-FNA cytology of the lesion was planned for a different time and was prioritized for those patients at higher risk for cancer. The accuracy, efficiency and quality assessment for the early detection of patients with potentially curable malignant lesions were evaluated for the whole cohort and in the different classes of MRSs. The time to definitive cytological diagnosis (TDCD), accuracy, sensitivity, specificity, positive and negative predictive values, and the rate of inconclusive tests were calculated for all patients and for each MRS group. A total of 1019 patients with suspected malignant lesions were evaluated by EUS-FNA. In 515 patients of 616 with true malignant lesions the tumor was diagnosed by EUS-FNA; 421 patients with resectable lesions received early surgical treatment, and 94 patients received chemo-radiotherapy. The overall diagnostic accuracy for the 1019 lesions in which a final diagnosis was obtained by EUS-FNA was 0.95. When patients were stratified by MTE into 4 classes of MRSs, a higher rate of patients in the group with higher cancer risk (MRS-3) received early treatment and EUS-FNA showed the highest level of accuracy (1.0). TDCD was also shorter in the MRS-3 group. The number of patients who received surgical treatment or chemo-radiotherapy was significantly higher in the MRS-3 patient group (36.3% in MRS-3, 10.7% in MRS-2, and 3.5% in MRS-1). EUS-FNA can effectively detect a curable malignant lesions at an earlier time and at a higher rate in patients with a higher cancer risk that were evaluated using MTE.

Aim of the Study. To compare the effect of glossopharyngeal nerve block with topical anesthesia on the tolerance of patients to upper gastrointestinal endoscopy. Methods. We performed a clinical trial in one hundred patients undergoing upper gastrointestinal endoscopy. Subjects were randomly assigned to one of the following two groups: (1) treatment with bilateral glossopharyngeal nerve block (GFNB) and intravenous midazolam or (2) treatment with topical anesthetic (TASS) and intravenous midazolam. We evaluated sedation, tolerance to the procedure, hemodynamic stability, and adverse symptoms. Results. We studied 46 men and 54 women, from 17 to 78 years of age. The procedure was reported without discomfort in 48 patients (88%) in the GFNB group and 32 (64%) in the TAAS group; 6 patients (12%) in GFNB group and 18 (36%) in TAAS group reported the procedure as little discomfort (χ (2) = 3.95, P = 0.04). There was no difference in frequency of nausea (4% in both groups) and retching, 4% versus 8% for GFNB and TASS group, respectively (P = 0.55). Conclusions. The use of glossopharyngeal nerve block provides greater comfort and tolerance to the patient undergoing upper gastrointestinal endoscopy. It also reduces the need for sedation.

Objective: To evaluate changes in nutritional status of hospitalized patients with different diseases by subjective global assessment (SGA) and nutritional risk screening (NRS-2002). Methods: A prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014. Hospitalized patients with the following diseases were investigated: malignant tumor (2 487 cases), benign disease of the digestive system (1 358 cases), benign disease of the nervous system (1 043 cases), benign bone disease (451 cases), benign disease of the respiratory system(395 cases), cardiovascular disease (227 cases), benign thyroid and breast disease (179 cases), and endocrine disease (149 cases). Patients above the age of 18 and hospitalization time between 7-30 days were included. Physical indexes were measured, the NRS-2002 and SGA scores were recorded, the nutritional support were recorded during hospitalization and 24 hours after discharge from hospital. Measurement data between groups were analyzed using t test or Wilcoxon rank sum test, enumeration data and ranked data between groups were analyzed using chi-square test or Fisher exact test. Results: There were 6 638 cases of hospitalized patients, 3 861 cases were males and 2 777 were females, the male/female ratio was 1.4∶1.0; the median age was 60 years; the median height was 1.66 m; the median weight was 62 kg; the median body mass index (BMI)was 22.89 kg/m(2). At discharge, compared with that of admission, the body weight, BMI, grip strength, upper arm and calf circumferences of patients with malignant tumor were significantly decreased ( t =20.15-259.67, all P <0.01); the body weight and calf circumference were significantly decreased ( t =35.27, 60.40, P <0.01)of patients with digestive benign disease; the body weight of patients with benign bone diseases was decreased ( t =2.12, P =0.033); the body weight, grip strength and upper arm circumference were decreased in patients with benign thyroid and breast disease ( t =2.79-10.18, all P <0.01); nutritional risk incidence rate (from NRS-2002) of patients with malignant tumor was significantly higher(χ(2)=21.275, P =0.000); moderate malnutrition (from SGA) incidence rate was significantly higher(χ(2)=62.318, P =0.000; χ(2)=11.312, P <0.01) in patients with malignant tumor and with orthopedics diseases. Compared with that of admission, records of the patients with other diseases had no statistically difference at discharge, no more than 50% of the patients under risk of nutritional deficiency(except those with digestive benign diseases )received nutritional support, while the proportion of non-parenteral nutrition application was higher. Conclusion: The patients with malignant tumor have higher incidence rate of malnutrition on admission and at discharge. Doctors should pay more attention to the nutritional status(screening and evaluation) of patients before discharge and use appropriate and adequate nutrition support in order to prevent the weight loss and improve the life quality of patients.

Fitz-Hugh-Curtis syndrome is defined as perihepatitis associated with pelvic inflammatory disease. Chlamydia trachomatis is one of its most common aetiologies. This syndrome usually presents with right upper quadrant abdominal pain mimicking other hepatobiliary and gastrointestinal pathologies, hence, posing a diagnostic dilemma in settings with limited diagnostic tools. A 32 year old African female presented with acute right upper quadrant abdominal pain and vaginal discharge, for which she had previously received treatment in another health center with no improvement. Clinical and laboratory findings were suggestive of Fitz-Hugh-Curtis syndrome. Five days after treatment with oral doxycycline, the patient showed marked clinical improvement. Fitz-Hugh-Curtis syndrome is a common cause of right upper quadrant pain which is often under diagnosed in poor communities. Hence, it should be included as a differential diagnosis in patients presenting with right upper quadrant pain, especially in females of reproductive age.

A 65-year-old male with bilateral decreased visual acuity for 3 weeks as well as bilateral hypoacusia, vertigo, disequilibrium, headache and decreased strength in the right upper limb for 4 months. The clinical work-up revealed a bilateral panuveitis and an ischemic cerebellar stroke. The diagnosis of Whipple disease was confirmed by histopathological analysis of adenopathy. The patient was treated with cortico-antibiotic therapy with significant clinical improvement. Although rare, Whipple disease is potentially fatal if left untreated, it must be always be taken into consideration before any panuveitis of an unknown cause, even in the absence of gastrointestinal symptoms.

Esophagitis and its causes: Who is “guilty” when acid is found “not guilty”?

PubMed Central

Grossi, Laurino; Ciccaglione, Antonio Francesco; Marzio, Leonardo

2017-01-01

Esophagitis is mainly a consequence of gastroesophageal reflux disease, one of the most common diseases affecting the upper digestive tract. However the esophageal mucosa can also be targeted by some infectious, systemic or chemical conditions. Eosinophilic esophagitis (EoE) is an immune-mediated inflammatory disease, characterized by eosinophilic infiltration in the mucosa. Esophageal localization of Crohn’s disease is not very common, but it should always be considered in patients with inflammatory bowel disease complaining of upper digestive tract symptoms. There are also forms of infectious esophagitis (e.g., Herpes simplex virus or Candida albicans) occurring in patients with a compromised immune system, either because of specific diseases or immunosuppressive therapies. Another kind of damage to esophageal mucosa is due to drug use (including oncologic chemotherapeutic regimens and radiotherapy) or caustic ingestion, usually of alkaline liquids, with colliquative necrosis and destruction of mucosa within a few seconds. Dysphagia is a predominant symptom in EoE, while infectious, drug-induced and caustic damages usually cause chest pain and odynophagia. Endoscopy can be useful for diagnosing esophagitis, although no specific pattern can be identified. In conclusion when a patient refers upper gastrointestinal tract symptoms and the diagnosis of gastro-esophageal reflux disease is not convincing we should always carefully investigate the patient’s clinical history to consider possibilities other than the gastric refluxate.

Helicobacter pylori and non-malignant upper gastrointestinal diseases.

Vasapolli, Riccardo; Malfertheiner, Peter; Kandulski, Arne

2016-09-01

Peptic ulcer disease (PUD) has been further decreased over the last decades along with decreasing prevalence of Helicobacter pylori-associated PUD. A delayed H. pylori eradication has been associated with an increased risk of rehospitalization for complicated recurrent peptic ulcer and reemphasized the importance of eradication especially in patients with peptic ulcer bleeding (PUB). PUB associated with NSAID/aspirin intake and H. pylori revealed an additive interaction in gastric pathophysiology which favors the "test-and-treat" strategy for H. pylori in patients with specific risk factors. The H. pylori-negative and NSAID-negative "idiopathic PUD" have been increasingly observed and associated with slower healing tendency, higher risk of recurrence, and greater mortality. Helicobacter pylori-associated dyspepsia has been further investigated and finally defined by the Kyoto consensus. Helicobacter pylori eradication therapy is advised as first option in this group of patients. Only in the case of symptom persistence or recurrence after eradication therapy, dyspeptic patients should be classified as functional dyspepsia (FD). There were few new data in 2015 on the role of H. pylori infection in gastroesophageal reflux disease (GERD), and in particular Barrett's esophagus. A lower prevalence of gastric atrophy with less acid output in patients with erosive esophagitis confirmed previous findings. In patients with erosive esophagitis, no difference was observed in healing rates neither between H. pylori-positive and H. pylori-negative patients nor between patients that underwent eradication therapy compared to patients without eradication. These findings are in line with the current consensus guidelines concluding that H. pylori eradication has no effects on symptoms and does not aggravate preexisting GERD. © 2016 John Wiley & Sons Ltd.

AIM: The use of low-dose aspirin to prevent cardiovascular disease events is well established. However, the incidence and predictors of upper gastrointestinal bleeding (UGIB) with its use are unknown. We studied prospectively the incidence and outcome of peptic ulceration in low-dose aspirin users. METHODS: A total of 991 patients with coronary artery disease (CAD) on low-dose aspirin were prospectively followed-up for two years for the occurrence and clinical features of first hospitalized episode of UGIB. RESULTS: UGIB had a bimodal presentation with 45% occurring within four months of aspirin initiation and had an overall prevalence of 1.5% per year. There was no UGIB-related death. Hypertension (OR = 4.6, 95%CI 1.5 - 14.7, P = 0.009), history of peptic ulceration (OR = 3.1, 95%CI 1.1 - 9.0, P = 0.039), tertiary education (OR = 3.08, 95%CI 1.1 - 9.0, P = 0.039) and higher lean body mass (P = 0.016) were independent factors associated with UGIB. Use of nitrate did not reduce UGIB. CONCLUSION: The incidence of UGIB in patients with CAD on long-term low-dose aspirin is low, but is accompanied with significant morbidity. With prolonged use of aspirin, UGIB continues to be a problem for those with risk factors and especially in patients with a history of peptic ulcers, in which UGIB tends to occur early after aspirin therapy.

New technology has considerably advanced the diagnosis of small-bowel pathology. However, its significance in clinical algorithms has not yet been fully assessed. The aim of the present analysis was to compare the diagnostic utility and yield of video-capsule enteroscopy (VCE) to that of magnetic resonance imaging (MRI) in patients with suspected or established Crohn's disease (Group I), obscure gastrointestinal blood loss (Group II), or suspected tumors (Group III). Forty-six out of 182 patients who underwent both modalities were included: 21 in Group I, 20 in Group II, and five in Group III. Pathology was assessed in three predetermined sections of the small bowel (upper, middle, and lower). The McNemar and Wilcoxon tests were used for statistical analysis. In Group I, lesions were found by VCE in nine of the 21 patients and by MRI in six. In five patients, both modalities showed pathology. In Group II, pathological changes were detected in 11 of the 20 patients by VCE and in eight patients by MRI. In five cases, pathology was found with both modalities. In Group III, neither modality showed small-bowel pathology. For the patient groups combined, diagnostic yield was 43% with VCE and 30% with MRI. The diagnostic yield of VCE was superior to that of MRI in the upper small bowel in both Groups I and II. VCE is superior to MRI for the detection of lesions related to Crohn's disease or obscure gastrointestinal bleeding in the upper small bowel.

Therapeutic potential of TAS-102 in the treatment of gastrointestinal malignancies

Peters, Godefridus J.

Fluoropyrimidines form the mainstay in treatment of gastrointestinal malignancies. For decades 5-fluorouracil (5FU), was the major fluoropyrimidine. Currently it is usually given in a combination with leucovorin and oxaliplatin, i.e. FOLFOX, or irinotecan, i.e. FOLFIRI, or all three, i.e. FOLFIRINOX, but gradually it has been replaced by oral fluoropyrimidine prodrug formulations, such as tegafur-uracil and S-1 (both contain ftorafur), and capecitabine (Xeloda®). Novel drugs such as the antivascular endothelial growth factor antibody, bevacizumab, and the anti-epidermal growth factor receptor antibody, cetuximab, are often combined with one of these treatment options. However, when resistance emerged, no alternatives were available. TAS-102, a combination of trifluorothymidine and the thymidine phosphorylase inhibitor TPI in a 1:0.5 ratio, is a novel oral formulation, which is active in 5FU-resistant models, both in vitro and in xenograft models. In addition to inhibition of thymidylate synthase, the major mechanism of action of classical fluoropyrimidines, TAS-102’s major mechanism of action is incorporation into DNA, thereby causing DNA damage. TAS-102 also follows an alternative activation pathway via thymidine kinase, and is not a substrate for dihydropyrimidine dehydrogenase. All together this explains the efficacy in 5FU-resistant models. In early clinical studies, the twice-daily schedule (5 days on, 2 days rest) for 2 weeks every 4 weeks, led to a significant disease control rate in various malignancies. This schedule showed consistent activity in two randomized trials on fluoropyrimidine refractory colorectal cancer patients, reflected by an increase of 2–3 months in overall survival in the TAS-102 group compared with placebo. Considering the impressive preclinical potential of various combinations TAS-102 has the promise to become an alternative for 5FU-resistant cancer. PMID:26557901

Abnormal Gastroesophageal Flap Valve Is Associated With High Gastresophageal Reflux Disease Questionnaire Score and the Severity of Gastroesophageal Reflux Disease in Vietnamese Patients With Upper Gastrointestinal Symptoms.

There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76-4.88) and RE (OR, 3.41; CI 95%, 1.78-6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) ( P ＜ 0.001). Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

Probably due to caffeine-induced gastric acid secretion, negative effects of coffee upon various upper-gastrointestinal diseases have been precariously accepted, despite the inadequate epidemiological evidence. Our aim is to evaluate the effect of coffee consumption on four major acid-related diseases: gastric ulcer (GU), duodenal ulcer (DU), reflux esophagitis (RE), and non-erosive reflux disease (NERD) based on the large-scale multivariate analysis. Of the 9,517 healthy adults, GU, DU, and RE were diagnosed by endoscopy, and NERD was diagnosed by the symptoms of heartburn and regurgitation without esophageal erosion. Associations between coffee consumption and the four disorders were evaluated, together with age, gender, body mass index (BMI), Helicobacter pylori (HP) infection status, pepsinogen I/II ratio, smoking, and alcohol. We further performed meta-analysis using the random effects model to redefine the relationship between coffee intake and peptic ulcer disease. The eligible 8,013 study subjects comprised of 5,451 coffee drinkers and 2,562 non-coffee drinkers. By univariate analysis, age, BMI, pepsinogen I/II ratio, smoking, and alcohol showed significant associations with coffee consumption. By multiple logistic regression analysis, positively correlated factors with significance were HP infection, current smoking, BMI, and pepsinogen I/II ratio for GU; HP infection, pepsinogen I/II ratio, and current smoking for DU; HP non-infection, male, BMI, pepsinogen I/II ratio, smoking, age, and alcohol for RE; younger age, smoking, and female for NERD. The meta-analyses could detect any association of coffee consumption with neither GU nor DU. In conclusion, there are no significant relationship between coffee consumption and the four major acid-related upper gastrointestinal disorders.

Laparoscopic surgery for benign and malign diseases of the digestive system: indications, limitations, and evidence.

The laparoscopic technique was introduced in gastrointestinal surgery in the mid 1980s. Since then, the development of this technique has been extraordinary. Triggered by technical innovations (stapling devices or coagulation/dissecting devices), nowadays any type of gastrointestinal resection has been successfully performed laparoscopically and can be performed laparoscopically dependent on the patient's condition. This summary gives an overview over 30 years of laparoscopic surgery with focus on today's indications and evidence. Main indications remain the more common procedures, e.g., appendectomy, cholecystectomy, bariatric procedures or colorectal resections. For all these indications, the laparoscopic approach has become the gold standard with less perioperative morbidity. Regarding oncological outcome there have been several high-quality randomized controlled trials which demonstrated equivalency between laparoscopic and open colorectal resections. Less common procedures like esophagectomy, oncological gastrectomy, liver and pancreatic resections can be performed successfully as well by an experienced surgeon. However, the evidence for these special indications is poor and a general recommendation cannot be given. In conclusion, laparoscopic surgery has revolutionized the field of gastrointestinal surgery by reducing perioperative morbidity without disregarding surgical principles especially in oncological surgery.

To evaluate the frequency of different sonographic splenic disorders in dogs with different anatomic forms of malignant lymphoma. Additionally, the occurrence of the moth-eaten pattern in the parenchyma of the spleen in patients with diseases other than lymphoma should be investigated. Retrospective analysis of patient data collected from dogs histologically or cytologically diagnosed with malignant lymphoma and for which ultrasonographic images were available before the initiation of therapy. Patient data from dogs with a moth-eaten pattern within the splenic parenchyma were evaluated separately. Exclusion criterion was the administration of cytostatic agents prior to diagnosis. In 84% of 164 dogs with malignant lymphoma, an altered pattern of the spleen was diagnosed ultrasonographically. Ninety-four of these 137 patients had a moth-eaten pattern of the splenic parenchyma and 43 dogs displayed abnormalities in the form of splenomegaly, coarse echotexture or other changes of the parenchyma. When a moth-eaten pattern was diagnosed, the affected dogs suffered significantly more often from a multicentric lymphoma (95%) than from any other anatomical lymphoma form. Only one dog displayed a moth-eaten pattern of the splenic parenchyma without diagnosis of a malignant lymphoma. The positive predictive value of the moth-eaten pattern for malignant lymphoma was 99% and, in particular, for the multicentric lymphoma this was 95%. In total, 84% of the 164 dogs displayed a multicentric lymphoma, 5% a mediastinal or a cutaneous lymphoma, respectively, 4% a gastrointestinal lymphoma, and one animal had an ocular or renal lymphoma, respectively. Sonographic changes of the spleen are often diagnosed in dogs with malignant lymphoma, independent of the anatomical lymphoma form. When the moth-eaten pattern is observed, it is very likely that the affected dog suffers from a malignant lymphoma, most probably a multicentric lymphoma.

Role of vitamins in gastrointestinal diseases

PubMed Central

Masri, Omar A; Chalhoub, Jean M; Sharara, Ala I

2015-01-01

A tremendous amount of data from research was published over the past decades concerning the roles of different vitamins in various gastrointestinal diseases. For instance, most vitamins showed an inverse relationship with the risk of colorectal carcinoma as well as other malignancies like gastric and esophageal cancer in observational trials, however interventional trials failed to prove a clear beneficial preventive role. On the other hand, more solid evidence was obtained from high quality studies for a role of certain vitamins in specific entities. Examples for this include the therapeutic role of vitamin E in patients with non-alcoholic steatohepatitis, the additive role of vitamins B12 and D to the standard therapy of chronic hepatitis C virus, the role of vitamin C in reducing the risk of gallstones, the positive outcome with vitamin B12 in patients with aphthous stomatitis, and the beneficial effect of vitamin D and B1 in patients with inflammatory bowel disease. Other potential uses are yet to be elaborated, like those on celiac disease, pancreatic cancer, pancreatitis, cholestasis and other potential fields. Data from several ongoing interventional trials are expected to add to the current knowledge over the coming few years. Given that vitamin supplementation is psychologically accepted by patients as a natural compound with relative safety and low cost, their use should be encouraged in the fields where positive data are available.

Critically ill patients may develop bleeding caused by stress ulceration. Acid suppression is commonly prescribed for patients at risk of stress ulcer bleeding. Whether proton pump inhibitors are more effective than histamine 2 receptor antagonists is unclear. To determine the efficacy and safety of proton pump inhibitors vs. histamine 2 receptor antagonists for the prevention of upper gastrointestinal bleeding in the ICU. We searched Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, ACPJC, CINHAL, online trials registries (clinicaltrials.gov, ISRCTN Register, WHO ICTRP), conference proceedings databases, and reference lists of relevant articles. Randomized controlled parallel group trials comparing proton pump inhibitors to histamine 2 receptor antagonists for the prevention of upper gastrointestinal bleeding in critically ill patients, published before March 2012. Two reviewers independently applied eligibility criteria, assessed quality, and extracted data. The primary outcomes were clinically important upper gastrointestinal bleeding and overt upper gastrointestinal bleeding; secondary outcomes were nosocomial pneumonia, ICU mortality, ICU length of stay, and Clostridium difficile infection. Trial authors were contacted for additional or clarifying information. Fourteen trials enrolling a total of 1,720 patients were included. Proton pump inhibitors were more effective than histamine 2 receptor antagonists at reducing clinically important upper gastrointestinal bleeding (relative risk 0.36; 95% confidence interval 0.19-0.68; p = 0.002; I = 0%) and overt upper gastrointestinal bleeding (relative risk 0.35; 95% confidence interval 0.21-0.59; p < 0.0001; I = 15%). There were no differences between proton pump inhibitors and histamine 2 receptor antagonists in the risk of nosocomial pneumonia (relative risk 1.06; 95% confidence interval 0.73-1.52; p = 0.76; I = 0%), ICU mortality (relative risk 1.01; 95% confidence interval 0.83-1.24; p = 0.91; I = 0%), or ICU length of stay (mean difference -0.54 days; 95% confidence interval -2.20 to 1.13; p = 0.53; I = 39%). No trials reported on C. difficile infection. In critically ill patients, proton pump inhibitors seem to be more effective than histamine 2 receptor antagonists in preventing clinically important and overt upper gastrointestinal bleeding. The robustness of this conclusion is limited by the trial methodology, differences between lower and higher quality trials, sparse data, and possible publication bias. We observed no differences between drugs in the risk of pneumonia, death, or ICU length of stay.

Management of complex acute surgical pathology in austere environments necessitates rapid evaluation and resource appropriate management to avoid time-associated morbidity and potentially mortality. Obstructive upper gastrointestinal (UGI) pathologies can be particularly challenging and associated with significant morbidity. Herein, we present six patients with UGI obstructions encountered over the course of an 8-mo deployment onboard a US Navy Aircraft Carrier. Each patient presented to our medical department with signs and symptoms of obstructive UGI pathology including one gastric volvulus requiring operative management at sea, one with a new diagnosis of achalasia requiring transportation and continental United States outpatient evaluation, and four patients with food impaction requiring urgent endoscopic management. Although UGI pathology is seldom encountered at sea, definitive surgical interventions, including prompt evaluation and management of these acute pathologies, can be performed in an austere environment. We wish to call attention to these potential encounters in order that underway deployed medical units and supporting resources ashore are prepared and equipped to intervene on acute UGI obstructive pathology. © Association of Military Surgeons of the United States 2018.

Gastrointestinal stromal tumors (61ST) are an heterogeneous group of non epithelial tumors of the gastrointestinal tract. They are peculiar to extreme cellular variability and uncertain malignancy. Gist are rare tumors that arise from primitive mesenchymal cells located in all gastrointestinal tract. Till now they are object of discussion about their origin, diagnostic standards, prognostic factors, histopathological classification. They are more frequently in over 40 years old people without difference in two sex, but they can appear in the child too and in the young man suffering from HIV. The authors relate two cases of recent observation, and discuss on the biological behaviour of these rare tumors.

Immunohistochemical features of the gastrointestinal tract tumors

PubMed Central

Wong, Hannah H.

2012-01-01

Gastrointestinal tract tumors include a wide variety of vastly different tumors and on a whole are one of the most common malignancies in western countries. These tumors often present at late stages as distant metastases which are then biopsied and may be difficult to differentiate without the aid of immunohistochemical stains. With the exception of pancreatic and biliary tumors where there are no distinct immunohistochemical patterns, most gastrointestinal tumors can be differentiated by their unique immunohistochemical profile. As the size of biopsies decrease, the role of immunohistochemical stains will become even more important in determining the origin and differentiation of gastrointestinal tract tumors. PMID:22943017

Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

Malignant transformation of mediastinal mature teratoma is extremely rare and worsens the prognosis of the disease. Transformation can appear synchronously to or several years after the initial diagnosis. Clinical and radiological signs can orientate the clinician but the definitive diagnosis is obtained thanks to histology. An 11 year-old boy presented with a mediastinal mature teratoma and bone and pulmonary metastases. He received six cycles of chemotherapy combining etoposide, ifosfamide, cisplatin, followed by resection of a 16×14×9cm mediastinal mass. Karyotype analysis revealed the presence of an additional sex chromosome X (47 XXY) pathognomonic of Klinefelter's syndrome. Ten years later, sciatalgia revealed malignant transformation of a pre-existing sacral bone metastasis into gastrointestinal adenocarcinoma. The patient received four cycles of chemotherapy combining oxaliplatin, 5-fluorouracil and cetuximab. This treatment was followed by a complete resection of the sacral metastasis and completed with adjuvant irradiation of 54Gy in 30 daily fractions. Twelve months after the diagnosis of relapse, the patient remained alive without disease. To our knowledge, this is the first case of adenocarcinoma developed in bone metastases of a mediastinal mature teratoma in a boy with a Klinefelter's syndrome. We propose a review of the literature and an analysis of 20 others published cases of mediastinal teratoma with malignant transformation into adenocarcinoma.

Viral pneumonias in patients with hematologic malignancies and recipients of hematopoietic stem cell transplantation cause significant morbidity and mortality. Advances in diagnostic techniques have enabled rapid identification of respiratory viral pathogens from upper and lower respiratory tract samples. Lymphopenia, myeloablative and T-cell depleting chemotherapy, graft-versus-host disease, and other factors increase the risk of developing life-threatening viral pneumonia. Chest imaging is often nonspecific but may aid in diagnoses. Bronchoscopy with bronchoalveolar lavage is recommended in those at high risk for viral pneumonia who have new infiltrates on chest imaging. Copyright © 2016 Elsevier Inc. All rights reserved.

Cerebral gas embolism as a result of upper gastrointestinal endoscopy is a rare complication and bares a high morbidity. A patient is presented who underwent an upper endoscopy for evaluation of a gastric-mediastinal fistula after subtotal oesophagectomy and gastric tube reconstruction because of oesophageal cancer. During the procedure, cerebral gas emboli developed resulting in an acute left-sided hemiparesis. After hyperbaric oxygen therapy, the patient recovered almost completely. The aetiology and treatment is discussed based on the reviewed literature. Once cerebral gas emboli are recognized, patient outcome can be improved by hyperbaric oxygen therapy.

To discuss the application of the degree of portal systemic shunting in assessing the upper gastrointestinal bleeding in patients with hepatic schistosomiasis. Thirty-three patients with upper gastrointestinal bleeding caused by hepatic schistosomiasis (a bleeding group) and 29 schistosomiasis cirrhosis patients without bleeding (a non-bleeding group) were enrolled as investigation subjects in Jinshan Hospital. The subjects were scanned by the 128 abdominal slice spiral CT. The portal systemic shunting vessels were reconstructed by using thin slab maximum intensity projection (TSMIP) and multiplanar reconstruction (MPR). The degrees of the shunting vessels of the subjects were evaluated and compared, and the relationship between upper gastrointestinal bleeding and the degree of the shunting was analyzed. In the bleeding group, the occurrence rates of the shunting vessels were found as follows: 86.4% in left gastric varices, 68.2% in short gastric varices, 50.0% in esophageal varices, 50.0% in para-esophageal varices, 37.9% in gastric varices, 69.7% in gastric-renal varices, 51.5% in spleen-renal varices, 25.8% in abdominal wall varices, 15.2% in omentum varices, 63.6% in para-splenic varices, 34.8% in umbilical varices, 40.9% in retroperitoneal-paravertebral varices, and 36.4% in mesenteric varices. In the bleeding group, the occurrence rates and the degree of shunt were significantly higher than those in the non-bleeding group in esophageal varices, esophageal vein, left gastric vein and gastric varices (all P < 0.05). CT portal vein reconstruction can accurately display the location, degree and walking of all kinds of shunting vessels. Esophageal varices, esophageal vein, left gastric vein and gastric varices can accurately predict the risk of upper gastrointestinal bleeding in patients with hepatic schistosomiasis. The patents with higher degree of the shunting vessels have a higher risk of gastrointestinal bleeding.

2018-03-28

We aimed to determine the rate of hospital readmission within 30 days of non-variceal upper gastrointestinal hemorrhage and its impact on mortality, morbidity, and health care use in the United States. We performed a retrospective study using the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmission Database for the year 2014 (data on 14.9 million hospital stays at 2048 hospitals in 22 states). We collected data on hospital readmissions of 203,220 adults who were hospitalized for urgent non-variceal upper gastrointestinal hemorrhage and discharged. The primary outcome was rate of all-cause readmission within 30 days of discharge. Secondary outcomes were reasons for readmission, readmission mortality rate, morbidity (shock and prolonged mechanical ventilation) and resource use (length of stay and total hospitalization costs and charges). Independent risk factors for readmission were identified using Cox regression analysis. The 30-day rate of readmission was 13%. Only 18% of readmissions were due to recurrent non-variceal upper gastrointestinal bleeding. The rate of death among patients readmitted to the hospital (4.7%) was higher than that for index admissions (1.9%) (P < .01). A higher proportion of readmitted patients had morbidities requiring prolonged mechanical ventilation (1.5%) compared with index admissions (0.8%) (P < .01). A total of 133,368 hospital days was associated with readmission, and the total health care in-hospital economic burden was $30.3 million (in costs) and $108 million (in charges). Independent predictors of readmission were Medicaid insurance, higher Charlson comorbidity score, lower income, residence in a metropolitan area, hemorrhagic shock, and longer stays in the hospital. Older age, private or no insurance, upper endoscopy, and prolonged mechanical ventilation were associated with lower odds for readmission. In a retrospective study of patients hospitalized for non-variceal upper gastrointestinal hemorrhage, 13% are readmitted to the hospital within 30 days of discharge. Readmission is associated with higher mortality, morbidity, and resource use. Most readmissions are not for recurrent gastrointestinal bleeding. Copyright © 2018 AGA Institute.

1997-11-01

To assess changes in practice and outcome in acute upper gastrointestinal haemorrhage following the feedback of data, the reemphasis of national guidelines, and specific recommendations following an initial survey. A prospective, multicentre, audit cycle. Forty five hospitals from three health regions participated in two phases of the audit cycle. Phase I: 2332 patients with acute upper gastrointestinal haemorrhage; phase II: 1625 patients with upper gastrointestinal haemorrhage. Patients were evaluated with respect to management (with reference to the recommendations in the national guidelines), mortality, and length of hospital stay. Following the distribution of data from the first phase of the National Audit and the formulation of specific recommendations for improving practice, the proportion of hospitals with local guidelines or protocols for the management of upper gastrointestinal haemorrhage rose from 71% (32/45) to 91% (41/45); 12 of the 32 hospitals with guidelines during the first phase revised their guidelines following the initial survey. There was a small but significant increase in the proportion of all patients who underwent endoscopy (from 81% to 86%), the proportion who underwent endoscopy within 24 hours of admission (from 50% to 56%), and the use of central venous pressure monitoring in patients with organ failure requiring blood transfusion or those with profound shock (from 30% to 43%). There was, however, no change in the use of high dependency beds or joint medical/surgical management in high risk cases. There was no significant change in crude or risk standardised mortality (13.4% in the first phase and 14.4% in the second phase). Although many of the participating hospitals have made efforts to improve practice by producing or updating guidelines or protocols, there has been only a small demonstrable change in some areas of practice during the National Audit. The failure to detect any improvement in mortality may reflect this lack of change of practice, but may also reflect the fact that a large proportion of the deaths in this unselected study are not preventable; only a very large study could hope to demonstrate a significant change out of the context of a clinical trial.

Background/Aims Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported the usefulness of EUS-FNA/B for rectal and perirectal lesions. This study reports our expanded experience with EUS-FNA/B for rectal and perirectal lesions in terms of diagnostic accuracy and safety. We also included our new experience with EUS-FNB using the recently introduced ProCore needle. Methods From April 2009 to March 2014, EUS-FNA/B for rectal and perirectal lesions was performed in 30 consecutive patients. We evaluated EUS-FNA/B performance by comparing histological diagnoses with final results. We also investigated factors affecting diagnostic accuracy. Results Among 10 patients with SETs, EUS-FNA/B specimen results revealed a gastrointestinal stromal tumor in 4 patients and malignant lymphoma in 1 patient. The diagnostic accuracy of EUS-FNA/B was 50% for SETs (5/10). Among 20 patients with non-SET lesions, 8 patients were diagnosed with malignant disease and 7 were diagnosed with benign disease based on both EUS-FNA/B and the final results. The diagnostic accuracy of EUS-FNA/B for non-SET lesions was 75% (15/20). The size of lesions was the only factor related to diagnostic accuracy (P=0.027). Two complications of mild fever and asymptomatic pneumoperitoneum occurred after EUS-FNA/B. Conclusions The overall diagnostic accuracy of EUS-FNA/B for rectal and perirectal lesions was 67% (20/30). EUS-FNA/B is a clinically useful method for cytological and histological diagnoses of rectal and perirectal lesions. PMID:25931998

Background The sodium/iodide symporter (NIS) is a plasma membrane glycoprotein that mediates iodide (I-) transport in the thyroid, lactating breast, salivary glands, and stomach. Whereas NIS expression and regulation have been extensively investigated in healthy and neoplastic thyroid and breast tissues, little is known about NIS expression and function along the healthy and diseased gastrointestinal tract. Methods Thus, we investigated NIS expression by immunohistochemical analysis in 155 gastrointestinal tissue samples and by immunoblot analysis in 17 gastric tumors from 83 patients. Results Regarding the healthy Gl tract, we observed NIS expression exclusively in the basolateral region of the gastric mucin-producing epithelial cells. In gastritis, positive NIS staining was observed in these cells both in the presence and absence of Helicobacter pylori. Significantly, NIS expression was absent in gastric cancer, independently of its histological type. Only focal faint NIS expression was detected in the direct vicinity of gastric tumors, i.e., in the histologically intact mucosa, the expression becoming gradually stronger and linear farther away from the tumor. Barrett mucosa with junctional and fundic-type columnar metaplasia displayed positive NIS staining, whereas Barrett mucosa with intestinal metaplasia was negative. NIS staining was also absent in intestinalized gastric polyps. Conclusion That NIS expression is markedly decreased or absent in case of intestinalization or malignant transformation of the gastric mucosa suggests that NIS may prove to be a significant tumor marker in the diagnosis and prognosis of gastric malignancies and also precancerous lesions such as Barrett mucosa, thus extending the medical significance of NIS beyond thyroid disease.

Intestinal occlusion due to intussusception produced by intestinal tumors is a very rare condition. Gastrointestinal stromal tumors are also rare digestive neopasias, with an impredictable malignant behavior, which are usually growing outside the intestinal wall, being rarely the initiators of an intestinal intussusception. We present the case of a 59 years old female, admitted in our hospital to elucidate the etiology of her iron deficient anaemia, which developed an intestinal occlusion at the intestinal preparation for colonoscopy. The abdominal CT scan performed in emergency conditions highlighted occlusive intestinal tumor complicated with intestinal intussusception. We performed an emergency laparotomy that revealed intestinal occlusion due to ileo-ileal intussusception produced by an ileal tumor. The surgical intervention consisted in segmental ileal enterectomy including the tumor with latero-lateral entero-enteral anastomosis. The patient recovered without complications. The histopathological and immunohisto-chemical examinations established the diagnose of gastro-intestinal stromal tumor with high risk malignant behavior, therefore the patient was guided in the oncological department for specific treatment and oncological surveillance.

Heterotopic gastric mucosa (HGM) of the esophagus is a congenital anomaly consisting of ectopic gastric mucosa. It may be connected with disorders of the upper gastrointestinal tract, exacerbated by Helicobacter pylori. The diagnosis of HGM is confirmed via endoscopy with biopsy. Histopathology provides the definitive diagnosis by demonstrating gastric mucosa adjacent to normal esophageal mucosa. HGM located in the distal esophagus needs differentiation from Barrett's esophagus. Barrett's esophagus is a well-known premalignant injury for adenocarcinoma of the esophagus. Malignant progression of HGM occurs in a stepwise pattern, following the metaplasia-dysplasia-adenocarcinoma sequence.We present a rare case of a teenage girl with HGM located in the distal esophagus, associated with chronic gastritis and biliary duodenogastric reflux. Endoscopy combined with biopsies is a mandatory method in clinical evaluation of metaplastic and nonmetaplastic changes within HGM of the esophagus.

2015-02-01

A 21-year-old woman presented with acute onset of upper abdominal pain. A diagnosis of Peutz-Jeghers syndrome (PJS) was made based on the clinical picture of perioral pigmentation with imaging findings of transient jejunojejunal intussusceptions and small bowel polyps, and confirmed by characteristic histopathological appearances of Peutz-Jeghers polyps. PJS is a rare hereditary condition characterised by unique hamartomatous polyps, perioral mucocutaneous pigmentations, and increased susceptibility to gastrointestinal and extraintestinal neoplasms. Patients usually present with recurrent abdominal pain due to intussusception caused by polyps. Other modes of presentations include rectal bleeding and melaena. We describe the imaging findings of PJS and provide a brief review of bowel polyposis syndromes. The latter are relatively rare disorders characterised by multiple polyps in the large or small intestine, with associated risk of malignancies and other extraintestinal manifestations. Awareness of the manifestations and early diagnosis of these syndromes is crucial to prevent further complications.

Extraskeletal osteosarcoma (EOS) is a highly aggressive and rare malignant soft tissue tumor, characterized by the production of neoplastic osseous tissue without attachment to the bone or periosteum. It rarely involves the visceral organs. Only 3 cases of mesenteric EOS have been reported in English literature. Here, we describe a male patient of 40 years, who was diagnosed to have EOS arising from small bowel mesentery. This patient presented with lower gastrointestinal (GI) bleeding. Upper GI endoscopy and colonoscopy were normal. Computed tomography scan demonstrated a well defined multi-loculated mixed density mass lesion measuring about 13x7x7 cm in lower abdomen adjacent to small bowel loops with liver metastasis. Palliative en bloc resection of tumor with adjacent small bowel was performed. The histopathology revealed a telangiectatic type osteosarcoma of mesentery. Diagnosis of EOS, its management and the outcome in context of the current literature are discussed.

Aspirin is an effective analgesic and antiplatelet drug that in addition to its ability to reduce pain, inflammation and fever, appears to have efficacy in the prevention/treatment of a range of diseases including heart disease, numerous cancers and Alzheimer's. It is important to understand the bioavailability of aspirin and its major metabolite, salicylic acid, since dosage and route of administration can vary for treating differing diseases, and the major side-effects of aspirin, upper gastrointestinal ulceration and bleeding, are dose-dependent. We examined the time course for gastroduodenal uptake of aspirin and the appearance of its major metabolite salicylic acid in blood and lymph after intragastric (to simulate oral) and intraduodenal (to simulate enteric-coating) dosing in rats. Results show that after intragastric dosing, intact aspirin is absorbed primarily by the gastric mucosa and to a lesser extent by the duodenal mucosa. When aspirin is dosed intragastrically or intraduodenally, a much greater concentration of aspirin enters the lymph than the blood. In contrast, the concentration of salicylic acid was higher in blood than in lymph. Lymph levels of both aspirin and salicylic acid were sufficiently high so as to perform a pharmacologic function there, possibly as a chemopreventive agent against colon cancer and potentially the metastatic spread of non-gastrointestinal cancers.

Upper Gastrointestinal Complications and Cardiovascular/Gastrointestinal Risk Calculator in Patients with Myocardial Infarction Treated with Aspirin.

Aspirin is widely used for the prevention of cardiovascular and cerebrovascular diseases for the past few years. However, much attention has been paid to the adverse effects associated with aspirin such as gastrointestinal bleeding. How to weigh the benefits and hazards? The current study aimed to assess the feasibility of a cardiovascular/gastrointestinal risk calculator, AsaRiskCalculator, in predicting gastrointestinal events in Chinese patients with myocardial infarction (MI), determining unique risk factor(s) for gastrointestinal events to be considered in the calculator. The MI patients who visited Shapingba District People's Hospital between January 2012 and January 2016 were retrospectively reviewed. Based on gastroscopic data, the patients were divided into two groups: gastrointestinal and nongastrointestinal groups. Demographic and clinical data of the patients were then retrieved for statistical analysis. Univariate and multiple logistic regression analyses were used to identify independent risk factors for gastrointestinal events. The receiver operating characteristic (ROC) curves were used to assess the predictive value of AsaRiskCalculator for gastrointestinal events. A total of 400 MI patients meeting the eligibility criteria were analyzed, including 94 and 306 in the gastrointestinal and nongastrointestinal groups, respectively. The data showed that age, male gender, predicted gastrointestinal events, and Helicobacter pylori (HP) infection were positively correlated with gastrointestinal events. In multiple logistic regression analysis, predicted gastrointestinal events and HP infection were identified as risk factors for actual gastrointestinal events. HP infection was highly predictive in Chinese patients; the ROC curve indicated an area under the curve of 0.822 (95% confidence interval: 0.774-0.870). The best diagnostic cutoff point of predicted gastrointestinal events was 68.0‰, yielding sensitivity and specificity of 60.6% and 93.1%, respectively, for predicting gastrointestinal events in Chinese patients with MI. AsaRiskCalculator had a predictive value for gastrointestinal events in Chinese patients with MI. HP infection seemed to be an independent risk factor for gastrointestinal events caused by long-term aspirin treatment in Chinese patients with MI, and it should be included in the risk calculator adapted for Chinese patients.

Black esophagus: Acute esophageal necrosis syndrome

PubMed Central

Gurvits, Grigoriy E

2010-01-01

Acute esophageal necrosis (AEN), commonly referred to as “black esophagus”, is a rare clinical entity arising from a combination of ischemic insult seen in hemodynamic compromise and low-flow states, corrosive injury from gastric contents in the setting of esophago-gastroparesis and gastric outlet obstruction, and decreased function of mucosal barrier systems and reparative mechanisms present in malnourished and debilitated physical states. AEN may arise in the setting of multiorgan dysfunction, hypoperfusion, vasculopathy, sepsis, diabetic ketoacidosis, alcohol intoxication, gastric volvulus, traumatic transection of the thoracic aorta, thromboembolic phenomena, and malignancy. Clinical presentation is remarkable for upper gastrointestinal bleeding. Notable symptoms may include epigastric/abdominal pain, vomiting, dysphagia, fever, nausea, and syncope. Associated laboratory findings may reflect anemia and leukocytosis. The hallmark of this syndrome is the development of diffuse circumferential black mucosal discoloration in the distal esophagus that may extend proximally to involve variable length of the organ. Classic “black esophagus” abruptly stops at the gastroesophageal junction. Biopsy is recommended but not required for the diagnosis. Histologically, necrotic debris, absence of viable squamous epithelium, and necrosis of esophageal mucosa, with possible involvement of submucosa and muscularis propria, are present. Classification of the disease spectrum is best described by a staging system. Treatment is directed at correcting coexisting clinical conditions, restoring hemodynamic stability, nil-per-os restriction, supportive red blood cell transfusion, and intravenous acid suppression with proton pump inhibitors. Complications include perforation with mediastinal infection/abscess, esophageal stricture and stenosis, superinfection, and death. A high mortality of 32% seen in the setting of AEN syndrome is usually related to the underlying medical co-morbidities and diseases. PMID:20614476

cetuximab, an epidermal growth factor receptor inhibitor, is a targeted therapeutic regimen of colorectal cancers. Several common adverse effects have been found, such as cutaneous or gastrointestinal toxicity. However, according to the articles had been published, upper gastrointestinal bleeding (UGIB) is considered to be rare and its mechanism remains unclear. In this report, we presented a 42-year-old male patient with advanced recto-sigmoid cancer. After palliative operation, the patient suffered from complete upper gastrointestinal (GI) obstruction, which was induced by extensive abdominal metastasis of the tumor. Considering his poor condition, we chose the targeted drug, cetuximab, as his further treatment. But after the application of cetuximab, the UGIB immediately happened twice in this patient. UGIB, as a rare complication of cetuximab, occured to the patient. We stopped the bleeding with thrombin, hemocoagulase and somatostatin and suspended the subsequent treatment plan of cetuximab. At the same time, anti-shock treatment was given immediately. He was died of respiratory and circulatory failure caused by UGIB and advanced tumor eventually. UGIB should be considered as a rare but severe complication of cetuximab. When cetuximab is applied for patients with advanced colon tumors, more cautions should be required if the patients are accompanied by upper gastrointestinal obstruction. In addition, for those patients who suffered from UGIB recently, cetuximab should be prohibited if the Rockall score ranged > 5 points. Copyright © 2017 The Authors.

Recreational Waterborne Illnesses: Recognition, Treatment, and Prevention.

PubMed

Perkins, Allen; Trimmier, Marirose

2017-05-01

Illness after recreational water activities can be caused by a variety of agents, including bacteria, viruses, parasites, algae, and even chlorine gas. These illnesses are more common in summer. Waterborne illnesses are underreported because most recreational activity occurs in unsupervised venues or on private property, and participants tend to disperse before illness occurs. Symptoms of waterborne illness are primarily gastrointestinal, but upper respiratory and skin manifestations also occur. Gastrointestinal symptoms are usually self-limited, and supportive treatment may be all that is necessary. However, some infections can cause significant morbidity and mortality. Cryptosporidium and Giardia intestinalis are the most common cause of gastrointestinal illness and have partial chlorine resistance. Respiratory infections are typically mild and self-limited. However, if legionnaires' disease develops and is unrecognized, mortality may be as high as 10%. Cellulitis caused by Vibrio vulnificus can result in serious illness, amputation, and death. Early and appropriate antibiotic treatment is important. Chronically ill and immunocompromised persons are at high risk of infection and should be counseled accordingly.

To study the influence of esophageal cancer surgeon volume upon mortality from upper gastrointestinal emergencies. Volume-outcome relationships led to the centralization of esophageal cancer surgery. Hospital Episode Statistics data were used to identify patients admitted to hospitals within England (1997-2012). The influence of esophageal high-volume (HV) cancer surgeon status (≥5 resections per year) upon 30-day and 90-day mortality from esophageal perforation (EP), paraesophageal hernia causing obstruction or gangrene (PEH) and perforated peptic ulcer (PPU) was analyzed, independent of HV esophageal cancer center status and patient and disease-specific confounding factors. A total of 3707, 12,411, and 57,164 patients with EP, PEH, and PPU, respectively, were included. The observed 90-day mortality was 36.5%, 11.5%, and 29.0% for EP, PEH, and PPU, respectively.Management by HV cancer surgeon was independently associated with significant reductions in 30-day and 90-day mortality from EP (odds ratio, OR 0.51, 95% confidence interval, CI, 0.40-0.66), PEH (OR=0.70, 95% CI 0.53-0.91), and PPU (OR=0.85, 95% CI 0.7-0.95). Subset analysis of those patients receiving primary surgery as treatment showed no change in mortality when performed by HV cancer surgeons.However HV cancer surgeons performed surgery as primary treatment more commonly for EP (OR=2.38, 95% CI 1.87-3.04) and PEH (OR=2.12, 95% CI 1.79-2.51). Furthermore surgery was independently associated with reduced mortality for all 3 conditions. The complex elective workload of HV esophageal cancer surgeons appears to lower the threshold for surgical intervention in specific upper gastrointestinal emergencies such as EP and PEH, which in turn reduces mortality.

We report a case of severe upper gastrointestinal hemorrhage with a rare underlying cause. The patient was unconscious when he was admitted to the hospital. No chest radiogram was performed. Routine diagnostic measures, including endoscopy, failed to reveal the origin of the bleeding, which was believed to originate from the esophagus secondary to a peptic ulcer or varices. Exploratory laparotomy added no further information, but contrast-enhanced multislice computed tomography (MSCT) of the chest showed dextroposition of the widened aortic arch with a ruptured type-B dissection and a consecutive aorto-esophageal fistula (AEF). The patient died on the day of admission.

Upper gastrointestinal bleeding (UGIB) is a threatening condition leading to urgent hospitalization. This study aims to investigate etiology and outcome in UGIB patients in Iran. Medical records of GIB patients admitted to Alzahra referral hospital (in Isfahan) during 2010-2015 were retrospectively reviewed for demographic data, comorbidities, history of smoking and taking non-steroidal anti-inflammatory drugs (NSAIDs), presenting symptoms, endoscopic findings, therapeutic endoscopy, blood products' infusion, surgical intervention, rebleeding, and mortality. A total of 4747 patients were enrolled in the study (69.2% men, mean age = 55.46 ± 21.98 years). Hematemesis was the most frequent presenting symptom (63.5%). Peptic ulcer (duodenal ulcer in most cases) was seen as the main reason for UGIB (42.4%). Rebleeding (present in 16.5% of patients) was found to be more frequent in patients with older age, presenting sign of hematochezia and hypotension, history of taking NSAIDs and smoking, presence of comorbidities, history of bleeding because of UGI tract neoplasm and esophageal varices, history of needing blood products' infusion, and history of therapeutic endoscopy or surgical intervention (P < 0.005). We found that mortality (5.5% in total) was also higher in the same group of patients that were seen to have a higher tendency for rebleeding (P < 0.005). Peptic ulcers are the most common cause of UGIB. Comorbidities, hemodynamic instability, high-risk endoscopic stigmata, history of smoking and taking NSAIDs, gastric and esophageal malignancies, may be important predisposing factors for rebleeding and mortality in patients with UGIB. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Outpatient management of low-risk patients with upper gastrointestinal bleeding: can we safely extend the Glasgow Blatchford Score in clinical practice?

PubMed

Mustafa, Zia; Cameron, Allan; Clark, Elaine; Stanley, Adrian J

2015-05-01

The Glasgow Blatchford Score (GBS) is a validated prognostic score for patients presenting with upper gastrointestinal (GI) bleeding (UGIB). The score predicts the need for therapeutic intervention or death, and studies have suggested that outpatient management is safe for patients with a GBS of zero. Our aim was to assess whether we could safely extend the threshold for outpatient management to patients with GBS≤1. Following assessment of our historical data, our UGIB protocol was changed to recommend outpatient management for patients with a GBS≤1, unless required for other reasons. Data on all patients presenting with UGIB over the following 12 months were prospectively recorded, including GBS and clinical Rockall scores. Adverse outcomes were defined by a 30-day combined endpoint of death, endotherapy, interventional radiology, surgery or transfusion. Negative predictive value (NPV) of GBS≤1 for adverse outcomes in UGIB was calculated. A total of 514 patients presented with UGIB in the 12 month study period. Of the patients, 183 (35.6%) had GBS≤1 (111, GBS=0; 72, GBS=1). Of these, 88 (48.1%) were managed as outpatients, and none had an adverse outcome. Of the 95 (51.9%) patients with GBS≤1 managed as inpatients, 80 (84.2%) had comorbidities requiring inpatient care. Within this admitted group with GBS≤1, one patient required transfusion and one died from a nongastrointestinal malignancy. GBS≤1 had an NPV of 99.45% (95% confidence interval 95.53-99.97%) in predicting adverse outcomes within 30 days. GBS≤1 has a high NPV for adverse outcomes in UGIB. This suggests outpatient management of patients with UGIB and that GBS≤1 is safe in our population.

The aim of this study was to evaluate the short- and long-term safety experience of infliximab treatment in patients with Crohn's disease (CD) in clinical practice. The medical records of 297 consecutive patients with CD treated with infliximab at the Beth Israel Deaconess Medical Center were reviewed for demographic features and adverse events. The 297 patients received a total of 1794 infusions. Patients received a median of four infusions and had a median follow-up of 14.3 months. Forty-four patients (15%) experienced a serious adverse event, requiring the infusion to be stopped in 33 patients (11%). Acute infusion reactions occurred in 18 patients (6%) including respiratory problems in 10 patients (3%) and an anaphylactoid reaction in 1 patient (0.3%). Serum sickness-like disease occurred in one patient (0.3%) and three patients (1%) developed drug-induced lupus. One patient developed a probable new demyelination disorder. Eight patients (2.7%), all of whom were on concurrent immunosuppressants, developed a serious infection, one resulting in fatal sepsis. Six patients (2%) developed malignancies including two lymphomas and two skin cancers. A total of four (1.3%) deaths were observed (median age 72.5 years); two due to gastrointestinal bleeding, one due to sepsis, and one due to malignancy. While short- and long-term infliximab therapy was generally well tolerated, serious adverse events occurred in 15% of patients including drug-induced lupus, fatal sepsis, and malignancy. Concomitant immunosuppressants were significantly associated with infections and deaths, particularly among elderly patients. Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.

To evaluate the safety of dose escalated radiotherapy using a simultaneous integrated boost technique in patients with locally advanced gynecological malignancies. Thirty-nine women with locally advanced gynecological malignancies were treated with intensity modulated radiation therapy utilizing a simultaneous integrated boost (SIB) technique for gross disease in the para-aortic and/or pelvic nodal basins, sidewall extension, or residual primary disease. Women were treated to 45Gy in 1.8Gy fractions to elective nodal regions. Gross disease was simultaneously treated to 55Gy in 2.2Gy fractions (n=44 sites). An additional sequential boost of 10Gy in 2Gy fractions was delivered if deemed appropriate (n=29 sites). Acute and late toxicity, local control in the treated volumes (LC), overall survival (OS), and distant metastases (DM) were assessed. All were treated with a SIB to a dose of 55Gy. Twenty-four patients were subsequently treated with a sequential boost to a median dose of 65Gy. Median follow-up was 18months. Rates of acute>grade 2 gastrointestinal (GI), genitourinary (GU), and hematologic (heme) toxicities were 2.5%, 0%, and 30%, respectively. There were no grade 4 acute toxicities. At one year, grade 1-2 late GI toxicities were 24.5%. There were no grade 3 or 4 late GI toxicities. Rates of grade 1-2 late GU toxicities were 12.7%. There were no grade 3 or 4 late GU toxicities. Dose escalated radiotherapy using a SIB results in acceptable rates of acute toxicity. Copyright © 2014 Elsevier Inc. All rights reserved.

Upper gastrointestinal endoscopy (UGI-ES) and double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) are two major image-based methods to diagnose atrophic gastritis, which is mostly induced by Helicobacter pylori infection. However, there have been few studies directly comparing them. Atrophic gastritis was evaluated using the data of 962 healthy subjects who underwent UGI-ES and UGI-XR within 1 year. Based on UGI-ES and UGI-XR, 602 subjects did not have atrophic gastritis and 254 subjects did have it. Considering UGI-ES-based atrophic gastritis as the standard, sensitivity and specificity of UGI-XR-based atrophic gastritis were 92.0 % (254/276) and 92.8 % (602/649), respectively. The seven-grade Kimura-Takemoto classification of UGI-ES-based atrophic gastritis showed a strong and significant association with the four-grade UGI-XR-based atrophic gastritis. Sensitivity and specificity of serum anti-Helicobacter pylori IgG to detect UGI-ES/UGI-XR-based atrophic gastritis were 89.4 % (227/254) and 99.8 % (601/602), indicating that atrophic gastritis can be overlooked according to serum anti-Helicobacter pylori IgG alone.

The incidence of clinically relevant anastomotic leaks after upper gastrointestinal surgery is approximately 4% to 20%, and the associated mortality is up to 80%. Depending on the clinical presentation, the treatment options include surgery, conservative treatment with or without external drainage or endoscopic treatment. This report presents nine cases of anastomotic leaks or fistulae after surgery for upper gastrointestinal cancers that were treated by insertion of a Vicryl plug and sealing with fibrin glue. Under sedation, all nine patients underwent endoscopic lavage of the cavity at the site of anastomotic leakage. The entrance to the cavity then was filled with Vicryl mesh and sealed off with fibrin glue. After the procedure, the patients underwent endoscopy and a water-soluble contrast study for assessment of the result. Seven of the nine patients had complete healing of the anastomotic leak or fistula after one to two endoscopic treatments. In one case, the treatment failed immediately because of a large and direct tracheoesophageal fistula. Another patient experienced recurrent intrathoracic abscesses after initial technical success. Postoperative upper gastrointestinal fistulas or anastomotic leaks can be managed successfully with little morbidity by means of endoscopic insertion of Vicryl mesh with fibrin glue, thereby avoiding repetitive major surgery and its associated risks.

Upper gastrointestinal cancers contribute significantly to cancer-related morbidity and mortality in sub-Saharan Africa, but they continue to receive limited attention. The high incidence in young adults remains unexplained, and the risk factors have not been fully described. A literature search was conducted using the electronic database PubMed. Beginning from January 1980 to February 2016, all articles evaluating biomass smoke exposure with oesophageal and gastric cancer were reviewed. Over 70% of the African population relies on biomass fuel, meaning most Africans are exposed to biomass smoke throughout their lives. Cigarette smoke is an established risk factor for upper gastrointestinal cancers, and some of its carcinogenic constituents are also present in biomass smoke. We found eight case-control studies reporting associations between exposure to biomass smoke and oesophageal cancer, and two linking biomass smoke to gastric cancer. All of these papers reported significant positive associations between exposure and cancer risk. Further research is needed in order to fully define the constituents of biomass smoke, which could each have varying specific and synergistic or independent contributions to the development of upper gastrointestinal cancers. Exposure to biomass smoke is an environmental factor influencing the development of upper gastrointestinal cancers, especially in low-resource settings.

Chronic Cough: Evaluation and Management.

PubMed

Michaudet, Charlie; Malaty, John

2017-11-01

Although chronic cough in adults (cough lasting longer than eight weeks) can be caused by many etiologies, four conditions account for most cases: upper airway cough syndrome, gastroesophageal reflux disease/laryngopharyngeal reflux disease, asthma, and nonasthmatic eosinophilic bronchitis. Patients should be evaluated clinically (with spirometry, if indicated), and empiric treatment should be initiated. Other potential causes include angiotensin-converting enzyme inhibitor use, environmental triggers, tobacco use, chronic obstructive pulmonary disease, and obstructive sleep apnea. Chest radiography can rule out concerning infectious, inflammatory, and malignant thoracic conditions. Patients with refractory chronic cough may warrant referral to a pulmonologist or otolaryngologist in addition to a trial of gabapentin, pregabalin, and/or speech therapy. In children, cough is considered chronic if present for more than four weeks. In children six to 14 years of age, it is most commonly caused by asthma, protracted bacterial bronchitis, and upper airway cough syndrome. Evaluation should focus initially on these etiologies, with targeted treatment and monitoring for resolution.

Objective The co-occurrence of general medical conditions (GMCs) and major psychiatric disorders is well documented. The aim of this study was to assess the prevalence of GMCs in patients with a primary diagnosis of obsessive-compulsive disorder (OCD) and, secondly, to investigate which clinical variables are associated with the presence of a GMC. Methods Subjects with a primary diagnosis of OCD were included. Socio-demographic and clinical characteristics were collected. GMCs were classified using the ICD-10 and grouped according to the Cumulative Illness Rating Scale (CIRS) in: cardiac, vascular, hematopoietic, respiratory, ear/nose/throat, upper and lower gastrointestinal, hepatic, renal, genitourinary, musculoskeletal, neurologic, endocrine/metabolic. The association between the presence of GMCs and demographic/clinical variables of OCD was investigated. Results A total of 162 patients with OCD were included. 78 (48.1%) patients had at least one comorbid GMC. Most frequent GMCs were endocrine/metabolic diseases (25.9%), followed by upper/lower gastrointestinal (20.5%) and cardio-vascular diseases (13.6%). The presence of a GMC was significantly associated with female gender, older age, duration of untreated illness (DUI), and absence of physical activity. Conclusion Patients with OCD have high rates of comorbid GMCs. A longer DUI is associated with having at least one GMCs; this might be due to the long-lasting adoption of unhealthy lifestyles, not counterbalanced by appropriate treatment and psychoeducation.

Malignant melanoma of the vulva in childhood is a rare neoplasm. Lichen sclerosus of the vulva in childhood is also a rare disease. The association of these two rare lesions in the vulva of young girls is extremely rare. We present a 10-year-old white girl with malignant melanoma associated with lichen sclerosus of the vulva. She had dark pigmentation of both the labia minora and posterior fourchette. The inner labia majora and fourchette showed whitish, glistening areas of skin. Histologic examination found mostly an in situ lentiginous/mucosal melanoma with focal invasion to a depth of 0.44 mm in the left upper labium majus. All specimens showed evidence of lichen sclerosus. Partial vulvectomy was performed, and no metastases were detected at the time of treatment. The patient has been disease free for the 12 months after treatment. It is critical for physicians to realize that melanoma can occur in children, and although rare, can occur in the vulva. We feel that lichen sclerosus in this instance may represent a pattern of host immune response to melanoma.

Autism spectrum disorder (ASD) is often accompanied by gastrointestinal disturbances, which also may impact behavior. Alterations in autonomic nervous system functioning are also frequently observed in ASD. The relationship between these findings in ASD is not known. We examined the relationship between gastrointestinal symptomatology, examining upper and lower gastrointestinal tract symptomatology separately, and autonomic nervous system functioning, as assessed by heart rate variability and skin conductance level, in a sample of 120 individuals with ASD. Relationships with co-occurring medical and psychiatric symptoms were also examined. While the number of participants with significant upper gastrointestinal tract problems was small in this sample, 42.5% of participants met criteria for functional constipation, a disorder of the lower gastrointestinal tract. Heart rate variability, a measure of parasympathetic modulation of cardiac activity, was found to be positively associated with lower gastrointestinal tract symptomatology at baseline. This relationship was particularly strong for participants with co-occurring diagnoses of anxiety disorder and for those with a history of regressive ASD or loss of previously acquired skills. These findings suggest that autonomic function and gastrointestinal problems are intertwined in children with ASD; although it is not possible to assess causality in this data set. Future work should examine the impact of treatment of gastrointestinal problems on autonomic function and anxiety, as well as the impact of anxiety treatment on gastrointestinal problems. Clinicians should be aware that gastrointestinal problems, anxiety, and autonomic dysfunction may cluster in children with ASD and should be addressed in a multidisciplinary treatment plan.

The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdominal computed tomography demonstrated free air and ascites in the abdominal cavity. In the pelvic cavity, a radiopaque linear shadow about 35mm in diameter was shown in the small intestine, and the stricture was exposed to the abdominal cavity. Therefore, a diagnosis of perforation of the small intestine due to ingestion of a foreign body and panperitonitis was made. Emergent laparotomy was performed. The intraoperative findings revealed perforation of the small intestine with a fish bone in the jejunum. Local inflammation at the perforation site was seen, and circulated wall thickness was observed at the distal side of the jejunum. Partial resection of the jejunum and anastomosis of jejuno-jejunostomy was performed. A pathological examination and immunohistochemical study of the resected specimen resulted in a diagnosis of malignant lymphoma of follicular lymphoma Grade 1. It is very difficult to identify the existence malignancy accompanied with gastrointestinal perforation with ingestion of a foreign body. In cases suspected of involving malignancy, careful observation during surgery is needed in order to avoid missing the accompanying malignancy. Copyright © 2017 The Authors.

Testicular cancer is the most common solid malignancy affecting males between the ages of 15 and 35. The symptomatology caused by this tumor varies according to the site of metastasis. We present the case of a 26-year-old male who arrived to the emergency department with hematemesis. He had no previous medical history. On arrival, we noted enlargement of the left scrotal sac. There was also a mass in the left scrotum which provoked displacement of the penis and right testis. The serum alpha-fetoprotein level was 17,090 ng/mL, lactate dehydrogenase was 1480 U/L, and human chorionic gonadotropin was 287.4 IU/mL. Upper endoscopy revealed a type 1 isolated gastric varix, treated with cyanoacrylate. A CT scan showed extrinsic compression of the portal vein by lymphadenopathy along with splenic vein partial thrombosis, which caused left-sided portal hypertension. Neoadjuvant chemotherapy was started with etoposide and cisplatin, and seven days later the patient underwent left radical orchiectomy. A postoperative biopsy revealed a pure testicular teratoma. Noncirrhotic left portal hypertension with bleeding from an isolated gastric varix secondary to metastasic testicular cancer has not been described before. Clinicians must consider the possibility of malignancy in the differential diagnosis of a young man presenting with unexplained gastrointestinal bleeding.

We report the rare case of a 72-year-old man with double cancers (gastric adenocarcinoma and Hodgkin's lymphoma) with collision between gastric adenocarcinoma and Hodgkin's lymphoma. Abdominal computed tomography showed increased wall thickness in the fundus region of the stomach and multiple lymph node swellings in the lesser curvature, periceliac and left cardial regions. Upper gastrointestinal endoscopy showed an ulcer approximately 5 cm in diameter with a malignant appearance in the fundus region of the stomach. On histopathologic examination, two completely different tumors were recognized in the stomach. One tumor was a poorly differentiated adenocarcinoma characterized by poorly developed tubular structures associated with prominent lymphoid infiltration of the stroma. The other tumor was found to have proliferated in the wall of the stomach, with diffuse granulomatous lesions and bordering the adenocarcinoma. Large atypical lymphoid cells with prominent nucleoli and enlarged mononuclei or multinuclei were seen in the latter tumor. Hodgkin's lymphoma was also found in the swollen lesser curvature lymph nodes. As a result, gastric adenocarcinoma and metastasis of Hodgkin's lymphoma were collided in the stomach. In conclusion, this case might be helpful in exploring the occurrence mechanism of tumor collision between lymphoma and carcinoma.

Livin belongs to the family of apoptosis inhibitors. High livin expression is observed in malignancies of the gastrointestinal tract, lungs, breast, and kidneys, but it is not present in differentiated adult tissues. In some malignant processes, anti‑livin antibodies are present. The aim of the study was to evaluate the prevalence of anti‑livin antibodies in Hashimoto thyroiditis, a disease characterized by rapid and widespread thyrocyte apoptosis. The study comprised 65 women with Hashimoto thyroiditis and the control group of 40 healthy women. In the majority of the patients, clinical manifestations of hypothyroidism were observed; all patients had high levels of serum antithyroid peroxidase antibodies. A solid‑phase radioimmunoassay in livin‑coated polyethylene tubes using 125I-labeled protein A was used to determine anti-livin antibodies. Significant amounts of anti-livin antibodies were reported in 18 patients (26.8%); 3 patients (4.6%) had borderline antibody levels; while in controls only 1 patient was positive (2.5%, P <0.0001). In Hashimoto thyroiditis, an autoimmune process is more general and involves numerous autoantibodies including an antibody against apoptosis inhibitor - livin. Anti‑livin antibodies cannot serve only as a marker of malignancy because they are also present in autoimmune processes.

To report an extragastrointestinal stromal tumor (EGIST) that occurs outside the gastrointestinal tract and shows unique clinicopathologic and immunohistochemical features. In our case, we experienced multiple soft tissue tumors that originate primarily in the greater omentum, and in immunohistochemical analysis, the tumors showed features that correspond to malignant EGIST. Two large omental masses measured 15 cm x 10 cm and 5 cm × 4 cm sized and several small ovoid fragments were attached to small intestine, mesentery and peritoneum. On histologic findings, the masses were separated from small bowel serosa and had high mitotic count (115/50 HPFs). In the results of immunohistochemical stains, the tumor showed CD117 (c-kit) positive reactivity and high Ki-67 labeling index. On mutation analysis, the c-kit gene mutation was found in the juxtamembrane domain (exon 11) and it was heterozygote. Platelet-derived growth factor receptor (PDGFR) gene mutation was also found in the juxtamemembrane (exon 12) and it was polymorphism. From above findings, we proposed that there may be several mutational pathways to malignant EGIST, so further investigations could be needed to approach this unfavorable disease entity.

To determine the frequency of metastatic ovarian tumors and to identify their clinicopathologic features. A total of 150 patients with pathologically confirmed metastatic ovarian carcinoma who were treated between 1995 and 2011 at the Mexican Oncology Hospital were identified by retrospective review. Clinicopathologic data were analyzed. Metastatic ovarian carcinoma accounted for 15.7% of all ovarian malignancies. The primary sites of nongynecologic tumors were the colon (30%), stomach (16%), appendix (13%), breast (13%), pancreas (12%), biliary tract (15%), and liver (4%). Gynecologic primary sites were the uterine cervix (4%) and the uterine body (23%). Primary malignancies were detected first in 66 patients (44%) and simultaneously with ovarian metastasis in 53 patients (35.3%). An ovarian mass was the first manifestation of disease in 20.6% of the cases. The patients ranged in age from 26 to 72 years (mean, 51). Krukenberg tumors were found in 35 patients (23%). The cut surfaces of the ovaries were solid in 68 patients, solid-cystic in 38, and multicystic in 44. Metastatic ovarian carcinomas are an important group of ovarian neoplasms, constituting 15.7% of all ovarian malignancies. Most of them arise from the gastrointestinal tract.

The mortality rate of ovarian cancer remains high due to late diagnosis and recurrence. A fundamental step toward improving detection and treatment of this lethal disease is to understand its origin. A growing number of studies have revealed that ovarian cancer can develop from multiple extra-ovarian origins, including fallopian tube, gastrointestinal tract, cervix and endometriosis. However, the mechanism leading to their ovarian localization is not understood. We utilized in vitro, ex vivo, and in vivo models to recapitulate the process of extra-ovarian malignant cells migrating to the ovaries and forming tumors. We provided experimental evidence to support that ovulation, by disrupting the ovarian surface epithelium and releasing chemokines/cytokines, promotes the migration and adhesion of malignant cells to the ovary. We identified the granulosa cell-secreted SDF-1 as a main chemoattractant that recruits malignant cells towards the ovary. Our findings revealed a potential molecular mechanism of how the extra-ovarian cells can be attracted by the ovary, migrate to and form tumors in the ovary. Our data also supports the association between increased ovulation and the risk of ovarian cancer. Understanding this association will lead us to the development of more specific markers for early detection and better prevention strategies. PMID:25135607

Exogenous provision of ALA to many tissues results in the accumulation of sufficient quantities of the endogenous photosensitizer protoporphyrin IX, (PpIX), to produce a photodynamic effect. Therefore, ALA may be considered the only current PDT agent in clinical development which is a biochemical precursor of a photosensitizer. Topical ALA application, followed by exposure to activating light (ALA PDT), has been reported effective for the treatment of a variety of dermatologic diseases including cutaneous T-cell lymphoma, superficial basal cell carcinoma, Bowen's disease, and actinic (solar) keratoses, and is also being examined for treatment of acne and hirsutism. PpIX induced by ALA application also may serve as a fluorescence detection marker for photodiagnosis (PD) of malignant and pre- malignant conditions of the urinary bladder and other organs. Local internal application of ALA has also been used for selective endometrial ablation in animal model systems and is beginning to be examined in human clinical studies. Systemic, oral administration of ALA has been used for ALA PDT of superficial head and neck cancer, various gastrointestinal cancers, and the condition known as Barrett's esophagus. This brief paper reviews the current clinical and development status of ALA PDT.

To analyse the clinicopathological findings of extranasal CD56+ cytotoxic T- or NK-cell lymphomas in different organs and to compare Epstein-Barr virus (EBV)+ and EBV- lymphoma of non-blastoid cytomorphology. Fifty-one cases of cCD3+ T-cell intracellular antigen (TIA-1)+ CD56+ lymphomas of extranodal/extranasal origin were included in the study. The primary sites of the CD56+ tumours were soft tissue (n = 10), the gastrointestinal (GI) tract (n = 13), the skin (n = 15), upper aerodigestive tract excluding nasal and nasopharyngeal regions (n = 11), the testis (n = 1), and parotid gland (n = 1). TCR gene rearrangement was detected in seven of 47 cases examined (16%). EBV was positive in 39 of 51 cases (76%). The positive rate of EBV was higher in tumours of soft tissue (80%), GI tract (92%), and skin (80%), and lowest in the upper aerodigestive tract excluding the nasal and nasopharyngeal region (50%). Tumours of the soft tissue and the upper aerodigestive tract tended to present with localized disease (P = 0.002). The 2-year survival rate was lowest for tumours of the GI tract (P = 0.0256). EBV- TCR- lymphoma showed less necrosis (P = 0.0133) and a better 2-year survival rate (P = 0.0066) than EBV+ TCR- lymphoma. Patients with EBV+ TCR+ lymphomas tended to present with localized disease, more often than EBV+ TCR- lymphoma (P = 0.0186). Significant prognostic factors in all CD56+ lymphomas were the site (P = 0.0256), EBV status (P = 0.0026), necrosis with or without perforation (P = 0.0338) and the presence of pleomorphic large tumour cells (P = 0.0428). Cox's regression analysis adjusting for other pathological parameters showed EBV status to be the only independent prognostic factor (P = 0.018). Extranodal CD56+ EBV- lymphoma at extranasal sites is a clinically less aggressive malignancy and displays less necrosis than CD56+ EBV+ lymphoma. Because CD56+ EBV+ TCR+ lymphomas show similar pathological and clinical findings to CD56+ EBV+ TCR- lymphomas, nasal-type NK/T-cell lymphomas at extranasal sites should be diagnosed as such on the basis of EBV+, cytotoxic T or NK phenotype irrespective of the genotype determined by molecular study.

To determine the prevalence and characteristics of sonographically evident upper-extremity deep vein thrombosis in symptomatic Chinese patients and identify its associated risk factors. Regional hospital, Hong Kong. Data on patients undergoing upper-extremity venous sonography examinations during a 13-year period from November 1999 to October 2012 were retrieved. Variables including age, sex, history of smoking, history of lower-extremity deep vein thrombosis, major surgery within 30 days, immobilisation within 30 days, cancer (history of malignancy), associated central venous or indwelling catheter, hypertension, diabetes mellitus, sepsis within 30 days, and stroke within 30 days were tested using binary logistic regression to understand the risk factors for upper-extremity deep vein thrombosis. The presence of upper-extremity deep vein thrombosis identified. Overall, 213 patients with upper-extremity sonography were identified. Of these patients, 29 (13.6%) had upper-extremity deep vein thrombosis. The proportion of upper-extremity deep vein thrombosis using initial ultrasound was 0.26% of all deep vein thrombosis ultrasound requests. Upper limb swelling was the most common presentation seen in a total of 206 (96.7%) patients. Smoking (37.9%), history of cancer (65.5%), and hypertension (27.6%) were the more prevalent conditions among patients in the upper-extremity deep vein thrombosis-positive group. No statistically significant predictor of upper-extremity deep vein thrombosis was noted if all variables were included. After backward stepwise logistic regression, the final model was left with only age (P=0.119), female gender (P=0.114), and history of malignancy (P=0.024) as independent variables. History of malignancy remained predictive of upper-extremity deep vein thrombosis. Upper-extremity deep vein thrombosis is uncommon among symptomatic Chinese population. The most common sign is swelling and the major risk factor for upper-extremity deep vein thrombosis identified in this study is malignancy.

Esophageal involvement in Hodgkin's disease, commonly known as a belated localization of the advanced forms, has been seldom reported (3 to 5% in post-mortem series and 0.7% in clinical series). We report the case of a 61-year-old man who had an esophagus localization revealing Hodgkin's disease stage IV EBb of Ann Arbor classification. The originality of this case was represented by: the revelation mode of the esophageal involvement such as dysphagia and upper gastrointestinal bleeding; the localization at the distal third of the esophagus with contiguous involvement of the gastric fundus; the absence of mediastinal nodes showing the primitive character of the esophageal injury. This observation incites us to consider Hodgkin's disease in the list of differential diagnoses of tumoral dysphagia, even if there was no ganglionic and/or visceral localization of the disease.

Chlamydia has been detected in the gastrointestinal tracts of both animals and humans. However, the mechanism by which Chlamydia colonizes the gut remains unclear. Chlamydia muridarum is known to spread from the genital to the gastrointestinal tracts hematogenously. The C. muridarum plasmid is a key pathogenic determinant in the mouse upper genital tract although plasmid-deficient C. muridarum is still able to colonize the upper genital tract. We now report that plasmid-deficient C. muridarum exhibits significantly delayed/reduced spreading from the mouse genital to the gastrointestinal tracts. C. muridarum with or without plasmid maintained similar levels in the mouse circulatory system following intravenous inoculation but the hematogenous plasmid-deficient C. muridarum was significantly less efficient in colonizing the gastrointestinal tract. Consistently, plasmid-deficient C. muridarum failed to restore normal colonization in the gastrointestinal tract even after intragastric inoculation at a high dose. Thus, we have demonstrated a plasmid-dependent colonization of C. muridarum in the gastrointestinal tract, supporting the concept that C. muridarum may have acquired the plasmid for adaptation to the mouse gastrointestinal tract during oral-fecal transmission. Since the plasmid is more important for C. muridarum to colonize the gastrointestinal tract than to infect the genital tract, the current study has laid a foundation for further defining the host pathways targeted by the plasmid-encoded or -regulated chlamydial effectors.

Advances in gastrointestinal bleeding.

Lanas, Ángel

2016-09-01

The main innovations of the latest meeting of the Gastroenterological Association (2016) concerning upper gastrointestinal bleeding from the clinician's perspective can be summarised as follows: a) The Glasgow-Blatchford scale has the best accuracy in predicting the need for surgical intervention and hospital mortality; b) Prognostic scales for non-variceal upper gastrointestinal bleeding are also useful for lower gastrointestinal bleeding; c) Preliminary data suggest that treatment with hemospray does not seem to be superior to current standard treatment in controlling active peptic ulcer bleeding; d) Either famotidine or a proton pump inhibitor may be effective in preventing haemorrhagic recurrence in patients taking aspirin, but this finding needs to be confirmed in further studies; e) There was confirmation of the need to re-introduce antiplatelet therapy as early as possible in patients with antiplatelet-associated gastrointestinal bleeding in order to prevent cardiovascular mortality; f) Routine clinical practice suggests that gastrointestinal or cardiovascular complications with celecoxib or traditional NSAIDs are very low; g) Dabigatran is associated with an increased incidence of gastrointestinal bleeding compared with apixaban or warfarin. At least half of the episodes are located in the lower gastrointestinal tract; h) Implant devices for external ventricular circulatory support are associated with early gastrointestinal bleeding in up to one third of patients; the bleeding is often secondary to arteriovenous malformations.

Bayesian network modelling of upper gastrointestinal bleeding

NASA Astrophysics Data System (ADS)

Aisha, Nazziwa; Shohaimi, Shamarina; Adam, Mohd Bakri

2013-09-01

Bayesian networks are graphical probabilistic models that represent causal and other relationships between domain variables. In the context of medical decision making, these models have been explored to help in medical diagnosis and prognosis. In this paper, we discuss the Bayesian network formalism in building medical support systems and we learn a tree augmented naive Bayes Network (TAN) from gastrointestinal bleeding data. The accuracy of the TAN in classifying the source of gastrointestinal bleeding into upper or lower source is obtained. The TAN achieves a high classification accuracy of 86% and an area under curve of 92%. A sensitivity analysis of the model shows relatively high levels of entropy reduction for color of the stool, history of gastrointestinal bleeding, consistency and the ratio of blood urea nitrogen to creatinine. The TAN facilitates the identification of the source of GIB and requires further validation.

The potential usefulness of standardized comprehensive geriatric assessment (CGA) in evaluating treatment and follow-up of older patients with upper gastrointestinal bleeding is unknown. To evaluate the usefulness of the CGA as a 2-year mortality multidimensional prognostic index (MPI) in older patients hospitalized for upper gastrointestinal bleeding. Patients aged > or =65 years consecutively hospitalized for acute upper gastrointestinal bleeding were included. Diagnosis of bleeding was based on clinical and endoscopic features. All patients underwent a CGA that included six standardized scales, i.e., Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Short Portable Mental Status Questionnaire (SPMSQ), Mini Nutritional Assessment (MNA), Exton-Smith Score (ESS) and Comorbity Index Rating Scale (CIRS), as well as information on medication history and cohabitation, for a total of 63 items. A MPI was calculated from the integrated total scores and expressed as MPI 1 = low risk, MPI 2 = moderate risk, and MPI 3 = severe risk. The predictive value of the MPI for mortality over a 24-month follow-up was calculated. 36 elderly patients (M 16/F 20, mean age 82.8 +/- 7.9 years, range 70-101 years) were included in the study. A significant difference in mean age was observed between males and females (M 80.1 +/- 4.8 vs. F 84.9 +/- 9.3 years; p < 0.05). The causes of upper gastrointestinal bleeding were duodenal ulcer in 38.8%, gastric ulcer in 22.2%, and erosive gastritis in 16.6% of the patients, while 16.6% had gastrointestinal bleeding from unknown origin. The overall 2-year mortality rate was 30.5%. 18 patients (50%) were classified as having a low-risk MPI (mean value 0.18 +/- 0.09), 12 (33.3%) as having a moderate-risk MPI (mean value 0.48 +/- 0.08) and 6 (16.6%) as having a severe-risk MPI (mean value 0.83 +/- 0.06). Higher MPI grades were significantly associated with higher mortality (grade 1 = 12.5%, grade 2 = 41.6%, grade 3 = 83.3%; p = 0.001). Adjusting for age and sex, the prognostic efficacy of MPI for mortality was confirmed and highly significant (odds ratio 10.47, 95% CI 2.04-53.6). CGA is a useful tool for calculating a MPI that significantly predicts the risk of 2-year mortality in older patients with upper gastrointestinal bleeding. Copyright 2007 S. Karger AG, Basel.

Riga-Fede disease is a benign and uncommon mucosal disorder. This illness is an ulceration of the oral mucosa and arises from repetitive traumatic injuries. The disease is usually caused by the sharp edges of new erupted teeth. The aim of the present case report is to present Riga-Fede disease and its treatment. We reported a 11-month-old healthy female infant diagnosed as Riga-Fede disease based on clinical features. After the conservative treatment that focused on eliminating the source of trauma, total healing was observed. Riga-Fede disease is rare. This illness can be confused with malignancies. Therefore, the diagnosis and treatment of this disease are very important for physicians and patients. © 2017 Wiley Periodicals, Inc.

OBJECTIVE To evaluate a method for identifying intact and degranulated eosinophils in the small intestine of dogs with inflammatory bowel disease (IBD) by use of a monoclonal antibody (mAb) against eosinophil peroxidase (EPX). ANIMALS 11 untreated dogs with IBD, 5 dogs with IBD treated with prednisolone, and 8 control dogs with no clinical evidence of gastrointestinal tract disease and no immunosuppressive treatment. PROCEDURES 4-μm-thick sections of paraffin-embedded tissues from necropsy specimens were immunostained with EPX mAb. Stained intact and degranulated eosinophils in consecutive microscopic fields (400X magnification) of the upper (villus tips) and lower (between the muscularis mucosae and crypts) regions of the lamina propria of the jejunum were manually counted. RESULTS Compared with control and treated IBD dogs, untreated IBD dogs had a significantly higher number of degranulated eosinophils in the lower region of the lamina propria. However, no significant differences were detected in the number of intact eosinophils in this region among groups. In the upper region of the lamina propria, untreated IBD dogs had a significantly higher number of degranulated and intact eosinophils, compared with control and treated IBD dogs. Number of degranulated and intact eosinophils did not differ significantly between control and treated IBD dogs. CONCLUSIONS AND CLINICAL RELEVANCE Immunohistologic analysis with EPX mAb yielded prominent granule staining that allowed reliable morphological identification of degranulated and intact eosinophils, which may provide a strategy for quantitative and selective evaluation of eosinophils in gastrointestinal biopsy specimens and a potential method to diagnose IBD and evaluate treatment outcome.

Dose to organs at risk in the upper abdomen in patients treated with extended fields by helical tomotherapy: a dosimetric and clinical preliminary study

PubMed Central

2013-01-01

Background The aim of this work was to determine the technical feasibility and safety of extended-field radiotherapy (EF), performed by Helical TomoTherapy, in patients with positive pelvic and/or para-aortic nodes. Dosimetric data were collected and acute and sub-acute toxicities of the upper abdominal organs at risk (OAR) were evaluated. Methods Twenty-nine patients suitable for EF irradiation for local disease and/or nodal disease in the pelvic or para-aortic area were treated. The prescription dose was 50.4/54 Gy (1.7-1.8 Gy/fraction) for prophylactic lymph nodes (N-) and 60–70.5 Gy (2–2.35 Gy/fraction) for clinically evident gross disease (N+). Modulation factor (MF), pitch and field width (FW) were chosen to optimize dose distribution and treatment duration. Dose values of PTVs and OAR were analysed. The length of the treatment field, the N + and N- volumes, and treatment duration were reported. To evaluate the safety of treatment, haematological, hepatic, renal and pancreatic functions were assessed before, during and after treatment. The median follow-up time was 17.6 months (range: 6–22 months). Results The treatment was well tolerated and all patients but one completed treatment without interruption. Four of the 29 patients experienced G3 haematological acute toxicity (13.8%), but no patient experienced sub-acute grade G3 toxicity. Ten patients experienced G1 and three G2 acute gastrointestinal toxicity (nausea). No sub-acute gastrointestinal or renal toxicity was observed. Only one (3.7%) patient had a persistent slight increase of pancreatic enzymes and two (7.4%) patients a slight increase of hepatic enzymes six months after radiotherapy (G1 toxicity). Conclusions With our treatment design and dose regimen, we found that EF treatment by TomoTherapy could be safely and effectively delivered with minimal acute and sub-acute toxicities in the upper abdomen area.

Bleeding 'downhill' esophageal varices associated with benign superior vena cava obstruction: case report and literature review.

PubMed

2016-10-24

Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices. Given the alternative pathophysiology of downhill varices, they require a unique approach to management. Variceal band ligation may be used to temporize acute variceal bleeding, and should be applied on the proximal end of the varix. Relief of the underlying SVC obstruction is the cornerstone of definitive treatment of downhill varices. A young woman with a benign superior vena cava stenosis due to a tunneled internal jugular vein dialysis catheter presented with hematemesis and melena. Urgent upper endoscopy revealed multiple 'downhill' esophageal varices with stigmata of recent hemorrhage. As there was no active bleeding, no endoscopic intervention was performed. CT angiography demonstrated stenosis of the SVC surrounding the distal tip of her indwelling hemodialysis catheter. The patient underwent balloon angioplasty of the stenotic SVC segment with resolution of her bleeding and clinical stabilization. Downhill esophageal varices are a distinct entity from the more common distal esophageal varices. Endoscopic therapies have a role in temporizing active variceal bleeding, but relief of the underlying SVC obstruction is the cornerstone of treatment and should be pursued as rapidly as possible. It is unknown why benign, as opposed to malignant, causes of SVC obstruction result in bleeding from downhill varices at such a high rate, despite being a less common etiology of SVC obstruction.

Nutritional Risk Screening-2002 (NRS-2002) has been recently used to evaluate the nutritional status of patients according to the recommendation of ESPEN. In this prospective study, we aimed to find the effectiveness of NRS-2002 on preoperative patients who were candidates for elective procedure at a general surgery clinic. The NRS-2002 scores of 698 patients were recorded in first 24 hours subsequent to their admission to hospital. The patients who had NRS-2002 score of 3 or 4 were accepted, and the scores were correlated with their age and clinical diagnosis. The nutritional status was good in 655 (93.9%) patients, and 43 patients (6.1%) were malnourished. A total of 135 patients had malignant disorders, among them 37 had concomitant malnutrition. The rate of malnutrition was 28.1% in patients with malignancy. The latter rate was 1.1% in patients with benign disorders. In patients who had gastrointestinal malignancy, the malnutrition rate was 31% (35/89), and the latter ratio was 6.5% (3/46) in patients who had malignancies arising from other than the gastrointestinal system. The NRS-2002 score was changed significantly according to age and malignancies (p<0.05). NRS-2002 can be easily used to evaluate the nutritional status of patients. This system is significant in deciding on nutritional support (Tab. 2, Ref. 12). Full Text (Free, PDF) www.bmj.sk.

Altered gastric anatomy following laparoscopic sleeve gastrectomy (LSG) is likely to induce upper gastrointestinal (GI) symptoms. Published studies, however, have focused mainly on gastroesophageal reflux disease (GERD). This study aims to evaluate LSG's impact on the prevalence of upper GI symptoms and to assess the effects of time from surgery, weight loss, and proton pump inhibitor (PPI) therapy. The validated Rome III Criteria symptom questionnaire for upper GI symptoms, including quality of life items, has been self-administered to 97 patients who underwent LSG. Symptoms were analyzed either separately or altogether to classify patients in GERD or dyspepsia, subdivided in epigastric pain (EPS) and post-prandial distress (PDS) syndromes. Before LSG, 52.7% of the patients were asymptomatic, 27.0% had GERD, and 8.1% had dyspepsia (2.7% EPS, 5.4% PDS). After a median follow-up of 13 months, 91.9% of the patients complained of upper GI symptoms, the most prevalent being PDS (59.4 %). GERD prevalence did not differ before and after LSG. The only symptom strongly related to LSG was dysphagia (OR 4.7, 95% CI 1.3-20.4, p = 0.015), which was present in 19.7% of the patients and mainly associated with PDS rather than GERD. GI symptoms, however, did not have a great impact on quality of life. Time from surgery, weight loss after surgery, as well as concomitant PPI, did not influence the symptoms. After a median follow-up of 13 months, PDS-like dyspepsia, rather than GERD, was the main complaint, both poorly responding to PPI therapy. A longer follow-up will be necessary to evaluate their future persistency.

Brain metastases of gastrointestinal origin are a rare occurrence. Radiation therapy (RT) in the form of stereotactic radiosurgery (SRS) or whole brain radiation therapy (WBRT) is an effective established treatment modality in either the definitive or adjuvant setting. The aim of this study is to assess the long-term clinical outcomes of patients with gastrointestinal (GI) brain metastases treated with SRS or WBRT. In this single institutional retrospective review, we detail the outcomes of patients diagnosed with metastatic brain tumors from an adenocarcinoma gastrointestinal primary. Patients were treated using stereotactic radiosurgery or whole brain radiation therapy. Initial site control (defined as lesions visualized on imaging at time of treatment), new site control (defined as new intracranial lesions visualized on follow-up imaging), and overall survival were calculated using the Kaplan-Meier method. Thirty-three patients were treated from August 2008 to December 2015. Primary malignancy locations were as follows: 18 colon, 6 esophagus, 4 rectum, 5 other. Median total dose delivered was 25 Gy (18-35 Gy) in a median of 4 fractions for SRS and 30 Gy (10.8-40 Gy) in 10 fractions for WBRT. Crude initial site control at last radiographic follow-up was 64.3% after SRS and 41.7% after WBRT. Eleven of the 28 brain lesions (39.3%) treated with SRS had resection of the SRS-treated lesion prior to radiation therapy. Five of the twelve patients (41.7%) undergoing WBRT underwent cranial resection prior to radiation therapy. Crude new site control at last radiographic follow-up was 46.4% after SRS and 83.3% after WBRT. Kaplan-Meier analysis of overall survival did not show any statistically significant difference between WBRT and SRS (p = 0.424). Median overall survival for SRS patients was 5.2 months (0.5-57.5) and for WBRT patients 4.4 months (0-15). Kaplan-Meier analysis of new site control was significantly improved with WBRT versus SRS (p = 0.017). Total dose, treatment with WBRT, and active extracranial disease were statistically significant on multivariate analysis for new site control (p < 0.05). Survival and intracranial disease control are poor following RT for brain metastases from GI primaries. In this small series, outcomes are worse than published series for other primary malignancies metastatic to the brain and further research into methods of local control improvement is warranted. Future studies should explore the utility of dose escalation or radiosensitization in this patient population.

It has recently been proposed that gastrointestinal stromal tumors (GISTs) originate from stem cells that differentiate toward a phenotype of interstitial cells of Cajal (ICCs). Nestin is a newly identified intermediate filament protein, and is predominantly expressed in immature cells, such as neuroectodermal stem cells and skeletal muscle progenitor cells, and tumors originating from these cells. In this study, we examined, using immunohistochemistry, the nestin expression in GISTs and ICCs to clarify the origin of GISTs. Strong immunoreactivity for nestin was observed in all 18 GISTs, and its expression was confirmed by Western blot and Northern blot analyses. In contrast, three leiomyomas and a schwannoma that developed in the gastrointestinal tract showed no apparent immunoreactivity for nestin. Among 17 mesenchymal tumors (seven leiomyosarcomas, five malignant peripheral nerve sheath tumors, and five fibrosarcomas) that occurred in sites other than the gastrointestinal tract, only two malignant peripheral nerve sheath tumors were moderately immunoreactive for nestin. Furthermore, with fluorescence double immunostaining of the normal small intestine, nestin expression was demonstrated in ICCs. These results show that nestin may be a useful marker for diagnosis of GISTs, and support the current hypothesis that GISTs are tumors of stem cells that differentiate toward an ICC phenotype.

Fungal infections of the liver, most commonly caused by Candida spp., often occur in patients with hematologic malignancies treated with chemotherapy. Colonization of the gastrointestinal tract is thought to be the main origin of dissemination of Candida; mucositis and neutropenia facilitate the spread of Candida from the gastrointestinal tract to the liver. Hepatic involvement due to other fungi is a less common infectious complication in this setting. Fungal infections represent a less common cause of hepatic abscesses in non-oncohematologic population and the trend appears to be decreasing in recent years. Understanding of the etiology and epidemiology of fungal infections of the liver is indicated for an appropriate antimicrobial therapy and an overall optimal management of fungal liver infections.

A 61-year-old woman with no significant past history underwent gastric biopsies demonstrating a strongly c-kit-positive epithelioid malignancy, initially thought to represent gastrointestinal stromal tumor (GIST). Subsequent clinical and immunohistochemical evaluation proved the neoplasm to represent metastatic lobular carcinoma. This case illustrates that although c-kit is highly specific and sensitive for GIST, its expression may occur in a variety of other neoplasms, some of which morphologically resemble GIST and may present in the gastrointestinal tract as metastases. Therefore, a review of other c-kit-positive lesions is also highlighted.

Mucosa associated lymphoid tissue (MALT) lymphomas are a group of non- Hodgkin"s lymphomas of low malignancy degree. The most frequent location is the gastrointestinal tract. Its primary pulmonary presentation is unusual and heterogeneous from point of view radiological. Woman 61 years old with antecedents of vitiligo, gastric ulcus, cirrhosis by VHC, that go into the hospital by sudden disnea, thoracic paint with pleural characterises and fever of 38.5 degrees C, Her thorax radiography and thoracic TAC showed nodes that affect to different pulmonary lobes. The cytology by PAAF confirms their malignant nature. In subsequent radiological controls it was notice the nodels took away completely and returns in different pulmonary place in each recurrence. The presentation like fluctuant pulmonary nodes is exceptional in a MALT lymphoma. It was described a higher incidence of VHC infection and tumour. The evidence of chronic hepatitis by virus C disease, and local chronic inflammatory process as well as autoimmune disorders may be considerate like a factor that contribute to MALT lymphoma.

Colorectal cancer (CRC) is one of the most common human malignancies and a leading cause of cancer-related deaths in developed countries. Identifying effective preventive strategies aimed at inhibiting the development and progression of CRC is critical for reducing the incidence and mortality of this malignancy. The prevention of carcinogenesis by anti-inflammatory agents including nonsteroidal anti-inflammatory drugs (NSAIDs), selective cyclooxygenase-2 (COX-2) inhibitors, and natural products is an area of considerable interest and research. Numerous anti-inflammatory agents have been identified as potential CRC chemopreventive agents but vary in their mechanism of action. This review will discuss the molecular mechanisms being studied for the CRC chemopreventive activity of NSAIDs (i.e., aspirin, sulindac, and ibuprofen), COX-2 inhibitors (i.e., celecoxib), natural products (i.e., curcumin, resveratrol, EGCG, genistein, and baicalein), and metformin. A deeper understanding of how these anti-inflammatory agents inhibit CRC will provide insight into the development of potentially safer and more effective chemopreventive drugs.

We aim to discuss the unusual clinical presentation of this case as well as the investigation and management of duodenocolic fistulas. PRESENTATION OF CASE A 91 year old lady presented as an emergency to a general surgical service at a District General Hospital with diarrhoea, vomiting and weight loss. Computed Tomography (CT) reported a large ovarian cyst elevating the sigmoid colon into immediate proximity of the duodenum. Adenocarcinoma was confirmed on histology obtained by colonoscopy. A classic apple core lesion with fistulating tract from the sigmoid colon to the duodenum was synchronously demonstrated on barium enema. DISCUSSION Sigmoido-duodenal fistulae represent a complex manifestation of gastrointestinal pathologies. CONCLUSION Management options must be considered in the context of patient wishes, their co-morbidities, and predicted post-operative outcome. In most cases this is likely to represent a non-operative approach, however surgical resection may benefit selected cases on occasion. PMID:25460456

How to stomach an epigenetic insult: the gastric cancer epigenome.

PubMed

Padmanabhan, Nisha; Ushijima, Toshikazu; Tan, Patrick

2017-08-01

Gastric cancer is a deadly malignancy afflicting close to a million people worldwide. Patient survival is poor and largely due to late diagnosis and suboptimal therapies. Disease heterogeneity is a substantial obstacle, underscoring the need for precision treatment strategies. Studies have identified different subgroups of gastric cancer displaying not just genetic, but also distinct epigenetic hallmarks. Accumulating evidence suggests that epigenetic abnormalities in gastric cancer are not mere bystander events, but rather promote carcinogenesis through active mechanisms. Epigenetic aberrations, induced by pathogens such as Helicobacter pylori, are an early component of gastric carcinogenesis, probably preceding genetic abnormalities. This Review summarizes our current understanding of the gastric cancer epigenome, highlighting key advances in recent years in both tumours and pre-malignant lesions, made possible through targeted and genome-wide technologies. We focus on studies related to DNA methylation and histone modifications, linking these findings to potential therapeutic opportunities. Lessons learned from the gastric cancer epigenome might also prove relevant for other gastrointestinal cancers.

Upper gastrointestinal bleeding in a patient with depression receiving selective serotonin reuptake inhibitor therapy.

Serotonin plays an important role in the normal clotting phenomenon and is released by platelets. Platelets are dependent on a serotonin transporter for the uptake of serotonin, as they cannot synthesize it themselves. Selective serotonin reuptake inhibitors (SSRIs) block the uptake of serotonin into platelets and can cause problems with clotting leading to bleeding. This case report highlights the occurrence of upper gastrointestinal bleeding in the index case on initiating SSRI therapy for depression and the prompt resolution of the same on its discontinuation on two separate occasions. SSRIs may cause upper gastrointestinal (GI) bleeding. Physicians should be aware of the same and should try to rule out previous episodes of upper GI bleed or the presence of other risk factors which might predispose to it before prescribing SSRIs; they should also warn the patients about this potential side effect. Also, the presence of thalassemia trait in the index patient deserves special attention and needs to be explored to see if it might in any way contribute in potentiating this side effect of SSRIs.

A 68-year-old man presented to the emergency department with haematemesis and shock. Upper endoscopy and selective angiography could not identify the source of bleeding. He underwent selective embolisation of the gastroduodenal artery. The patient then had a period of about 24 hours with relative haemodynamic stability before having another episode of massive upper gastrointestinal bleed. A second attempt to embolise the common hepatic artery and distal coeliac axis was unsuccessful. Hence, he was urgently taken to the operating room for exploratory laparotomy. The source of bleeding could not be identified in the operating room. The patient went into cardiac arrest and expired. Autopsy revealed a fistula between proximal jejunum and a previously unknown abdominal aortic aneurysm (AAA). We present an entity that has only been described a few times in the literature while highlighting the importance of having a broad differential with upper gastrointestinal bleeding, especially when the source is not clearly evident. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Ewing's sarcoma (ES) and primitive neuroectodermal tumors (PNET) are closely related tumors. Although soft tissue ES/PNET are common in clinical practice, they are rare in the small intestine. Because of the absence of characteristic clinical symptoms, they are easily misdiagnosed as other benign or malignant diseases. Here, we present the case of a 16-year-old female who complained of anemia and interval hematochezia. Her serum test results showed only a slight elevation of CA-125 and a low level of hemoglobin. Computer tomography and magnetic resonance imaging revealed a cystic and solid mass in the lower abdominal quadrant and pelvic region, which prompted suspicion of a malignant gastrointestinal stromal tumor of the small intestine. After resection, the tumor's histology and immunohistochemistry (positive for CD99, vimentin and synaptophysin) results suggested ES/PNET. Fluorescent in situ hybridization tests proved the breakpoint rearrangement of the EWSR1 gene in chr 22.Ultrastructural analysis revealed neurosecretory and glycogen granules in the tumor cell cytoplasm. Together, these data supported the diagnosis of a rare case of localized ES/PNET in the small intestine without adjuvant chemo- or radiotherapy. To our knowledge, this is the first report from China of a primary small bowel ES/PNET in the English-language literature. In addition, on the basis of findings from previous publications and the current case, the optimal treatment for localized gastrointestinal ES/PNET is discussed.

Endoscopy is extremely useful for the diagnosis of upper gastrointestinal bleeding. At the present time, therapeutic measures are been used during the endoscopy to stop bleeding. This paper reports the experience of hospital de Talca in the endoscopic treatment of upper gastrointestinal bleeding. Thirty four patients (22 male) with bleeding not originating from esophageal or gastric varices were treated with direct absolute alcohol injection into the bleeding lesions. The procedure was successful in 31 patients. Three of the 34 patients required surgery, but only one of those successfully sclerosed (97% success). There were no complications attributable to the procedure. It is concluded that this therapeutic modality must be implemented in places were gastrointestinal endoscopy is performed.

To study the clinicopathologic characteristics of perivascular epithelioid cell tumor (PEComa), not otherwise specified (NOS) and to evaluate the diagnostic criteria for malignancy. The clinical and pathologic features of 31 cases of PEComa-NOS were reviewed. The follow-up data available were analyzed. There were a total of 24 females and 7 males. The age of the patients ranged from 13 to 66 years (mean = 40 years). The site of tumor occurrence included gynecologic organs (n = 12), intraabdominal/peritoneal soft tissue (n = 10), gastrointestinal tract (n = 4), thigh (n = 2), mediastinum (n = 1), left groin (n = 1) and urinary bladder (n = 1). None of the cases was associated with tuberous sclerosis complex. Histologic examination showed that 23 cases (74%) were clear cell sugar tumor-like, 4 cases (13%) were clear cell myomelanocytic tumor-like and 4 cases (13%) were of mixed epithelioid-spindled morphology. According to the classification system proposed by Folpe et al, 19 cases (61%) were classified as malignant, 7 cases (23%) as PEComa of uncertain malignant potential and 5 cases (16%) as benign. The expression rates of HMB45, smooth muscle actin and desmin in tested cases were 100% (31/31), 67% (14/21) and 6/18, respectively. Follow-up data (1 to 56 months) were available in 23 cases (74%). Amongst the 16 cases of malignant PEComa, 7 patients were still alive with no evidence of disease, 6 patients were alive with unresectable or recurrent/metastatic disease and 3 patients died of the disease. The local recurrence and metastasis in those 16 cases were 6 cases and 5 cases, respectively. One of the 4 patients with PEComa of uncertain malignant potential died, while the remaining 3 patients and all of the patients with benign PEComa had an uneventful clinical course. The classification system of PEComas proposed by Folpe et al. is reliable in routine practice. Correlation with the clinical and radiologic findings however is prudent when dealing with core biopsy specimens or sampling from exploration laparotomy. Owing to the histologic heterogeneity of this entity, thorough understanding of the morphologic spectrum is essential in arriving at a correct diagnosis.

Ingested foreign bodies and food bolus impaction are frequently seen in endoscopic practice. Successful foreign body and food bolus removal may depend on the method used, the choice of device, and the experience level of the endoscopist, although few papers report experience and outcome of tertiary centers. To investigate the effectiveness of our protocol designed for removal of ingested foreign bodies and food boluses. We retrospectively reviewed all patients with a diagnosis of foreign body ingestion and food bolus impaction from 1994 to 2005 identified by computer search. Patients were excluded if medical record was incomplete. The analysis included 171 patients. Foreign bodies and impacted food boluses were found in 77 and 62 patients, respectively. In 32 cases (23%), the foreign bodies passed spontaneously through the gastrointestinal tract. The overall success rate for endoscopic management was obtained in 137 patients (98.6%). Surgical removal of a foreign body was required in only 2 cases (1.4%). According to the type and location of the foreign object and food bolus we used Dormia baskets, retrieval forceps, polypectomy snares, and all sizes of Roth net. No complications relating to the endoscopic procedure were observed; 50 patients (35.2%) had an underlying esophageal disease. Endoscopic removal of upper gastrointestinal tract foreign bodies and food bolus impaction is efficacious and safe. Especially the Roth net is the best device for safe retrieval of food boluses and button disc batteries.

Bile acids have been implicated in the development of gastrointestinal malignancies. Both the specific nature of individual bile acids and their concentration appear key factors in the carcinogenic potency of bile. Using liquid chromatography mass spectrometry (LC-MS) we performed quantitative profiling of bile extracted directly from the common bile duct in 30 patients (15 patients with pancreatic cancer and 15 patients with benign disease). Separation and detection of bile acids was performed using a 1.7μm particle size reversed-phase C 18 LC column at a flow rate of 200μL/min with negative electrospray ionization MS. A significant difference (p=0.018) was seen in the concentration of unconjugated cholic acid in the malignant group (0.643mmol/L) compared to the benign group (0.022mmol/L), with an overall significant difference (p=0.04) seen in the level of total unconjugated bile acids in the malignant group (1.816mmol/L) compared to the benign group (0.069mmol/L). This finding may offer the possibility of both understanding the biology of cancer development in the pancreas, as well as offering a potential diagnostic avenue to explore. However, a larger study is necessary to confirm the alterations in bile acid profiles reported here and explore factors such as diet and microbial populations on the bile acid profiles of these patient groups.

Gastrocolic fistula has been associated with a variety of diseases. Causative factors are most commonly gastric/colonic cancers and benign gastric ulcers. Treatment modalities may change according to etiology. In this study, we present our cases with gastrocolic fistula and the treatment modalities utilized for this uncommon complication. The records of the patients with gastrocolic fistula between November 1996 and June 2006 were retrospectively analyzed. Six patients with a mean age of 57.5 were determined. Of these, four had malignancy and two had gastric ulcer. The predominant symptoms were diarrhea and vomiting, weight loss, and abdominal pain. Diagnostic studies included barium enema, endoscopy, barium meal, colonoscopy, and computed tomography. After preoperative nutritional support, en-bloc resection of the involved gastrocolic region (4), simple excision (1), and wedge resection of the gastric part and closure of the colonic wall (1) were performed. One patient died of respiratory disorders and there was only one recurrence. In our series, therapeutic management for this unusual disorder included various resection procedures such as simple excision, which may result in recurrence, and wedge resection or en-bloc resection for benign cases, whereas en-bloc resection and reconstruction procedures remained the most applied management for malignant cases. En-bloc resection followed by combination of adjuvant chemotherapy results in long disease-free survival. Gastrocolic fistula should be suspected in patients with chronic diarrhea and vomiting of unknown cause with a high suspicion of gastrointestinal malignancy.

Some authors have investigated the effects of oxidative stress in some process such as undergoing laparoscopic. However, the effect of upper gastrointestinal system endoscopy process on oxidative stress is unclear. We evaluated the short-term effect of upper gastrointestinal system endoscopy process on oxidative stress. Thirty patients who underwent endoscopy process and 20 healthy controls were enrolled in the prospective study. Serum total antioxidant capacity and total oxidant status measurements were measured before and after endoscopy process. The ratio percentage of total oxidant status to total antioxidant capacity was regarded as oxidative stress index. Before endoscopy process, serum total antioxidant capacity levels were higher, while serum total oxidant status levels and oxidative stress index values were lower in patients than controls, but this difference was not statistically significant (all, p > 0.05). After endoscopy process, serum total antioxidant capacity and total oxidant status levels were significantly higher in patients than before endoscopy process (both, p < 0.05). However, oxidative stress index values were slight higher in patients but this difference was not statistically significant (p > 0.05). We observed that serum TAC and TOS levels were increased in patients who underwent endoscopy process after endoscopy process. However, short-time upper gastrointestinal system endoscopy process did not cause an important change in the oxidative stress index. Further studies enrolling a larger number of patients are required to clarify the results obtained here.

Background/Aims: To validate the AIMS65 score for predicting mortality of patients with nonvariceal upper gastrointestinal bleeding and to evaluate the effectiveness of urgent (<8 hours) endoscopic procedures in patients with high AIMS65 scores. Methods: This was a 5-year single-center, retrospective study. Nonvariceal, upper gastrointestinal bleeding was assessed by using the AIM65 and Rockall scores. Scores for mortality were assessed by calculating the area under the receiver-operating characteristic curve (AUROC). Patients with high AIMS65 scores (≥2) were allocated to either the urgent or non-urgent endoscopic procedure group. In-hospital mortality, success of endoscopic procedure, recurrence of bleeding, admission period, and dose of transfusion were compared between groups. Results: A total of 634 patients were analyzed. The AIMS65 score successfully predicted mortality (AUROC=0.943; 95% confidence interval [CI], 0.876 to 0.99) and was superior to the Rockall score (AUROC=0.856; 95% CI, 0.743 to 0.969) in predicting mortality. The group with high AIMS65 score included 200 patients. The urgent endoscopic procedure group had reduced hospitalization periods (p<0.05) Conclusions: AIMS65 score may be useful in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding. Urgent endoscopic procedures in patients with high scores may be related to reduced hospitalization periods. PMID:26668799

Acquired copper deficiency represents a rare cause of progressive myelopathy presenting with sensory ataxia and spastic gait. The time interval from neurological symptoms onset to diagnosis of myelopathy ranges from 2 months to several years in almost all cases, mimicking the clinical course of subacute combined degeneration due to vitamin B12 deficiency. A 60-year-old man, without any gastrointestinal symptoms, developed over the course of one week rapidly progressive gait imbalance, tingling and numbness in his feet and ascending lower limb weakness. Spine magnetic resonance imaging revealed hyperintensity involving cervical and dorsal posterior columns of spinal cord. Blood analysis revealed undetectable serum copper levels, low serum ceruloplasmin and positive serum Immunoglobulin A anti-tissue transglutaminase. Upper gastrointestinal endoscopy was performed revealing duodenal villous atrophy consistent with a malabsorption pattern. A gluten-free diet in association with intravenous then oral copper supplementation prompted sustained normalization of serum copper levels and progressive clinical improvement. We report a rare case of myelopathy induced by copper deficiency secondary to undiagnosed celiac disease, peculiarly presenting with a subacute onset. This case expands the neurological presentation and clinical course of myelopathy due to acquired copper deficiency. We suggest investigation of copper deficiency in patients presenting with subacute or even acute sensory ataxia and spastic gait. Detection of hypocupremia in patients without a previous history of gastric surgery should lead to diagnostic testing for celiac disease even in the absence of any obvious gastrointestinal symptoms.

care overload, aging of population, and increased chronic diseases lead to increased referrals from primary care, which may sometimes overload the health system. Thus, different interventions have been carried out attempting to improve these aspects. to assess the most frequent causes of consultation of general physicians, both in joint consultations and clinical sessions held jointly with specialist consultant in primary care, in the urban and rural setting, and the influence on referrals to first consultations of gastroenterology. a mainly training type of intervention was carried out, consisting of regular meetings in both urban and rural primary care center, to perform joint consultations and clinical sessions on patients and topics related to the specialty of gastroenterology. The intervention period (divided in two subperiods) was compared with a control period. most reasons for consultation were those corresponding to lower gastrointestinal tract, followed by liver disease and upper gastrointestinal tract. Significant differences were only found in distribution of diagnoses between the two centers in joint consultations. There was a relative (percent) decrease in referrals at the global level in both subperiods, only significant in the first (51.45 %), as well as in rural setting (45.24 %). common consultations motifs were similar in urban and rural settings, with some relevance of lower gastrointestinal tract disease. Most of them can be solved at primary care, with the help of consultant specialist. There is impact on referrals to the outpatient first consultations of gastroenterology, mainly in rural setting.

To explore the effectiveness of propeller facial artery perforator flap to repair the defect after resection of skin malignant tumor at upper lip. Between July 2012 and January 2017, 17 cases with skin malignant tumor at upper lip underwent tumor resection and the remained defect was repaired with propeller facial artery perforator flap. Among the 17 patients, 3 were male and 14 were female, with an average age of 57 years (range, 35-82 years). There were 5 cases of squamous cell carcinoma and 12 cases of basal cell carcinoma. The disease duration ranged from 4 months to 11 years with an average of 20 months. The tumor size ranged from 1.4 cm×0.3 cm to 3.1 cm×1.4 cm. The extended resection of the tumor tissue was performed according to the characters of tumor. According to the location, size, and shape of the defect and the position of facial artery perforator explored with Doppler ultrasonography, the propeller facial artery perforator flap was designed to repair the defect and partial donor site. The flap size ranged from 5 cm×2 cm to 7 cm×3 cm. The length of the perforator pedicle was 0.5-1.0 cm with an average of 0.8 cm. The defect at donor site was directly closed. Cyanosis occurred in 3 cases of the distal flap after operation, then healing after symptomatic treatment. The remaining flaps survived successfully and the wound healed by first intention. Primary healing was obtained in the donor site. All the patients were followed up 6-36 months with an average of 18 months. The shape of the patient's upper lip was good and the scar on the donor site was unconspicuous. There was no lip deformity, ala nasi deflection, facial tension, entilation dysfunction, or recurrence of tumor during follow-up. At last follow-up, the results of self-evaluation were very satisfactory in 13 cases and satisfactory in 4 cases. Based on multiple advantages of good blood supply, large rotation range, aesthetic outcome, and slight injury of the donor site, propeller facial artery perforator flap is not only an optimal choice for repairing upper lip defect after resection of skin malignant tumors, but also can achieve good functional and cosmetic effectiveness.

Dose and dose rate extrapolation factors for malignant and non-malignant health endpoints after exposure to gamma and neutron radiation.

Murine experiments were conducted at the JANUS reactor in Argonne National Laboratory from 1970 to 1992 to study the effect of acute and protracted radiation dose from gamma rays and fission neutron whole body exposure. The present study reports the reanalysis of the JANUS data on 36,718 mice, of which 16,973 mice were irradiated with neutrons, 13,638 were irradiated with gamma rays, and 6107 were controls. Mice were mostly Mus musculus, but one experiment used Peromyscus leucopus. For both types of radiation exposure, a Cox proportional hazards model was used, using age as timescale, and stratifying on sex and experiment. The optimal model was one with linear and quadratic terms in cumulative lagged dose, with adjustments to both linear and quadratic dose terms for low-dose rate irradiation (<5 mGy/h) and with adjustments to the dose for age at exposure and sex. After gamma ray exposure there is significant non-linearity (generally with upward curvature) for all tumours, lymphoreticular, respiratory, connective tissue and gastrointestinal tumours, also for all non-tumour, other non-tumour, non-malignant pulmonary and non-malignant renal diseases (p < 0.001). Associated with this the low-dose extrapolation factor, measuring the overestimation in low-dose risk resulting from linear extrapolation is significantly elevated for lymphoreticular tumours 1.16 (95% CI 1.06, 1.31), elevated also for a number of non-malignant endpoints, specifically all non-tumour diseases, 1.63 (95% CI 1.43, 2.00), non-malignant pulmonary disease, 1.70 (95% CI 1.17, 2.76) and other non-tumour diseases, 1.47 (95% CI 1.29, 1.82). However, for a rather larger group of malignant endpoints the low-dose extrapolation factor is significantly less than 1 (implying downward curvature), with central estimates generally ranging from 0.2 to 0.8, in particular for tumours of the respiratory system, vasculature, ovary, kidney/urinary bladder and testis. For neutron exposure most endpoints, malignant and non-malignant, show downward curvature in the dose response, and for most endpoints this is statistically significant (p < 0.05). Associated with this, the low-dose extrapolation factor associated with neutron exposure is generally statistically significantly less than 1 for most malignant and non-malignant endpoints, with central estimates mostly in the range 0.1-0.9. In contrast to the situation at higher dose rates, there are statistically non-significant decreases of risk per unit dose at gamma dose rates of less than or equal to 5 mGy/h for most malignant endpoints, and generally non-significant increases in risk per unit dose at gamma dose rates ≤5 mGy/h for most non-malignant endpoints. Associated with this, the dose-rate extrapolation factor, the ratio of high dose-rate to low dose-rate (≤5 mGy/h) gamma dose response slopes, for many tumour sites is in the range 1.2-2.3, albeit not statistically significantly elevated from 1, while for most non-malignant endpoints the gamma dose-rate extrapolation factor is less than 1, with most estimates in the range 0.2-0.8. After neutron exposure there are non-significant indications of lower risk per unit dose at dose rates ≤5 mGy/h compared to higher dose rates for most malignant endpoints, and for all tumours (p = 0.001), and respiratory tumours (p = 0.007) this reduction is conventionally statistically significant; for most non-malignant outcomes risks per unit dose non-significantly increase at lower dose rates. Associated with this, the neutron dose-rate extrapolation factor is less than 1 for most malignant and non-malignant endpoints, in many cases statistically significantly so, with central estimates mostly in the range 0.0-0.2.

Small intestinal tumors are rare with adenocarcinoma of the small intestine accounting for less than 2% of all gastrointestinal cancers. Primary jejunal adenocarcinoma constitutes a minute portion of small intestine adenocarcinomas. Clinically, this cancer presents at latter stages of its progression, mainly due to vague and non-specific symptoms, and the difficulty encountered in accessing the jejunum on upper endoscopy. Diagnosis of jejunal adenocarcinoma is usually inconclusive with the use of computed tomography (CT) scan, small bowel series, or upper endoscopy. Laparoscopy followed by frozen section biopsy provides a definitive diagnosis. In the past decade, balloon-assisted enteroscopy (BAE) and capsule endoscopy have become popular as useful modalities for diagnosing small bowel diseases. Wide excisional jejunectomy is the only treatment option with an estimated 5-year survival of 40-65%. Physicians are advised to suspect jejunal adenocarcinoma as a differential diagnosis in patients who present with non-specific symptoms of abdominal pain, nausea, vomiting, weight loss, anemia, gastrointestinal bleeding or signs of small bowel obstruction. We present a rare case of a 37-year-old woman with suspected bilateral ovarian masses, which was immunohistochemically confirmed as primary jejunal adenocarcinoma with bilateral ovarian metastasis.

Helicobacter pylori (H. pylori) has a big role in the relapse and pathogenesis of the upper gastrointestinal disease. Dyspepsia is characterized by uncomfortable feeling at the upper gastrointestinal area. IgA H. pylori antibody was in two-thirds of H. pylori infected patients, but about 7.2% of IgA H. Pylori antibody became the only positive result of the test between the two serology test (IgG and IgA). A cross-sectional study was conducted in 38 patients with dyspepsia. The IgA antibody test for H. pylori in the serum of dyspepsia patient conducted through the ELISA test. The hemoglobin levels, leukocytes, platelets number, and H. pylori infection via IgA antibody test on ulcer and non-ulcer dyspepsia patient had no significant difference. There was a relation between the number of platelets in the infected H. pylori patients compared to the non-infected patients. H. pylori infection in the ulcer and non-ulcer dyspepsia patient with serology method was 18%. H. pylori infection number on ulcer dyspepsia was not higher than the non-ulcer dyspepsia, all ulcer dyspepsia patients who were with H. pylori found with a lesion on the antrum.

In six cases of hyperthyroidism and two of chronic thyroiditis herein described, the initial features of the diseases were misinterpreted as attributable to other kinds of illness such as myocardial infarction, gastrointestinal malignant disease, malabsorption syndrome, psychosis, simple exophthalmos and endemic goiter. The characteristic signs and symptoms of hyperthyroidism (in six patients) and chronic thyroiditis (in two patients) were present at the outset but were not identified. Intensive questioning and alertness were required to elicit these characteristics. The symptoms improved or disappeared after the true disease was controlled. In the studies of these cases, the usefulness of a number of laboratory tests was illustrated—thyroid suppression studies, 4 to 6-hour and 24-hour radioactive iodine uptake, T3 uptake by the red cells and determinations of 24-hour urine creatine, antithyroglobulin antibody titer and long-acting thyroid stimulating hormone. The manifestations of thyroid diseases are many and varied. The term “masked hyperthyroidism” may in part be a reflection of the “masked physician” unless he uses his clinical detective abilities.

Primary malignant small bowel tumors: an atypical abdominal emergency.

Primary malignant tumors of the small bowel are uncommon in the United States. They comprise less than 1% of all gastrointestinal malignancies, with an incidence of 2200 cases per year. The clinical presentation of small bowel tumors is frequently insidious and often overlooked by physicians. The low incidence and lack of pathognomonic symptoms are the reasons that the early diagnosis of malignant small bowel tumor is uncommon. To better understand the clinical presentation, diagnostic evaluation, management, and outcome, a review of Howard University patients with primary malignant small bowel tumors between 1970 and 1990 was conducted. Our experience concurs with the reported literature and supports the conclusion that a high index of suspicion is necessary. The diagnosis of a malignant small bowel tumor should be considered in patients with vague chronic abdominal complaints. Images Figure 1 Figure 2 PMID:7752280

A 22-yr-old, captive-born, presumed female Hoffmann's two-toed sloth (Choloepus hoffmanni) presented in respiratory distress with severe dehydration and symptoms of hypotension. During treatment, dysphagia was noted and oral examination revealed enlarged palatine tonsils and mucosal plaques. Bloodwork showed a decreased sodium:potassium ratio, a low baseline cortisol, a decreased adrenocorticotropin response test, and a blunted aldosterone stimulation test. All values were compared to a healthy male Hoffmann's two-toed sloth at the same facility. Despite aggressive medical management and treatment for hypoadrenocorticism, the sloth was found deceased. Necropsy revealed abdominal effusion, multifocal plaques throughout the upper gastrointestinal tract, and testes. Histopathology showed marked adrenal cortical atrophy and intranuclear mucosal inclusions in the gastrointestinal tract; advanced molecular techniques did not uncover any viral etiologies. This is the first reported case of hypoadrenocorticism in a sloth.

Nonvariceal upper gastrointestinal hemorrhage is a frequent reason for ordinary hospital admission. In Italy the use of prognostic scores to stratify the risk has not been adequately validated: the impact on clinical management of a rating system like the Rockall score remains to be established. RING is a 'register' that has been collecting hospital discharge files from hospital gastroenterology units, giving a broad picture of the patients admitted for this pathology. We analyzed the hospital discharge files collected between 2001 and 2005 from 12 gastroenterology units, which issued more than 26,000 hospital discharge files for ordinary hospital admission and have been using the Rockall score for defining nonvariceal upper gastrointestinal hemorrhage since 2003. There were 2832 hospital discharge files with a main diagnosis of nonvariceal upper gastrointestinal hemorrhage: 1335 'before' the Rockall score was introduced, 1497 'after' the introduction. Patients' mean age was 67.7+/-16.7 years, with a male/female ratio of 1.7 and no significant changes over the years. There were no differences in the distribution of diagnoses in nonvariceal upper gastrointestinal hemorrhage patients before/after the introduction of the Rockall score, though the mean hospital stay became shorter (7.1+/-5.0 vs. 6.3+/-4.5 days), and mortality declined (2.8 vs. 2.3%), in parallel with the caselist as a whole. For 1102 ordinary hospital admission Rockall score was calculated. Diagnoses were more accurate: significantly fewer undefined causes and an increase in peptic ulcer. The mean Rockall score was 4.6+/-2.2: 17.8% low (0-2), 48.7% intermediate (3-5), and 33.5% high (>or=6). Mean hospital stay, rebleeding, and mortality were correlated with the severity of the score. The Rockall score enables the clinician to formulate a more precise diagnosis and substantially shortens the time in hospital, especially for patients at low-risk of rebleeding and death, so more resources can be dedicated to critically ill patients.

Predictors of Aggressive Inflammatory Bowel Disease

Yarur, Andres J.; Strobel, Sebastian G.; Deshpande, Amar R.

2011-01-01

Inflammatory bowel disease comprises a group of conditions characterized by idiopathic inflammation of the gastrointestinal tract. The natural course of disease can range from an indolent course with prolonged periods of remission to aggressive, incapacitating disease. Predicting which patients are more susceptible to developing severe disease is important, especially when choosing therapeutic agents and treatment strategies. This paper reviews current evidence on the main demographic, clinical, endoscopic, histologic, serologic, and genetic markers that predict aggressive inflammatory bowel disease. In ulcerative colitis, we considered disease to be aggressive when patients had a high relapse rate, need for admission and/or surgery, development of colon cancer, or extraintestinal manifestations. We defined aggressive Crohn's disease as having a high relapse rate, development of penetrating disease, need for repeat surgery, or multiple admissions for flares. In Crohn's disease, involvement of the upper gastrointestinal tract and ileum, penetrating disease, early age at diagnosis, smoking, extensive ulceration of the mucosa, high titers of serum antibodies, and mutations of the NOD2 gene are markers of aggressive disease. In ulcerative colitis, patients with more extensive involvement of the colon (pancolitis) have more symptomatology and are at higher risk for needing a colectomy and developing colon cancer. Also, plasmocytic infiltration of the colonic mucosa and crypt atrophy predict treatment failure. As with diagnosis, no single method can predict disease aggressiveness. Multiple serologic and genetic tests are being developed to refine the accuracy of prediction. Endoscopic findings can also predict the future course of disease. At present, clinical manifestations are the most useful way to make therapeutic decisions. PMID:22298958

Sister Mary Joseph nodule or node refers to a palpable nodule bulging into the umbilicus and is usually a result of a malignant cancer in the pelvis or abdomen. Traditionally it has been considered a sign of ominous prognosis. Gastrointestinal malignancies, most commonly gastric, colon and pancreatic cancer account for about 52% of the underlying sources. Gynecological cancers, most commonly ovarian and uterine cancers account for about 28% of the sources. PMID:19842232

To distinguish upper from lower gastrointestinal (GI) bleeding. Patient records between April 2011 and March 2014 were analyzed retrospectively (3296 upper endoscopy, and 1520 colonoscopy). Seventy-six patients had upper GI bleeding (Upper group) and 65 had lower GI bleeding (Lower group). Variables were compared between the groups using one-way analysis of variance. Logistic regression was performed to identify variables significantly associated with the diagnosis of upper vs lower GI bleeding. Receiver-operator characteristic (ROC) analysis was performed to determine the threshold value that could distinguish upper from lower GI bleeding. Hemoglobin (P = 0.023), total protein (P = 0.0002), and lactate dehydrogenase (P = 0.009) were significantly lower in the Upper group than in the Lower group. Blood urea nitrogen (BUN) was higher in the Upper group than in the Lower group (P = 0.0065). Logistic regression analysis revealed that BUN was most strongly associated with the diagnosis of upper vs lower GI bleeding. ROC analysis revealed a threshold BUN value of 21.0 mg/dL, with a specificity of 93.0%. The threshold BUN value for distinguishing upper from lower GI bleeding was 21.0 mg/dL.

To assess the consequences of switching aspirin dosage from 100 mg/d to 40 mg/d on cardiovascular benefit, bleeding risk and platelet aggregation in very elderly patients. Arachidonic acid induced platelet aggregation(AA-Ag) was measured in 537 patients aged 80 or older treated with aspirin (100 mg/d). In the study, 100 patients with low on-treatment platelet aggregation and at high risk of bleeding and low risk of cardiovascular events, were switched to aspirin (40 mg/d) and their platelet aggregation was measured again 7 days later.Their bleeding and upper gastrointestinal symptoms were also recorded in following 3 months. The study observed a heterogeneous distributed aspirin 100 mg/d AA-Ag (range: 0.42% to 28.78%)in the 537 very elderly patients.Aspirin 100 mg/d AA-Ag before the switch in aspirin 40 mg/d group was 5.00%±2.32% and the rate of the patients with low on-treatment platelet aggregation was 71.00%. The rates of melena or occult blood positive, other minimal bleeding,upper gastrointestinal symptoms and a history of gastrointestinal bleeding in 40 mg/d group were higher than those in 100 mg/d group. On a regimen of aspirin 40 mg/d, AA-Ag increased to 11.21%±4.95%(range: 2.12% to 28.84%) with 95.00%of the patients with AA-Ag<20% and the rate of the patients with low on-treatment platelet aggregation was 15.00%. Multiple variable analysis revealed that aspirin 40 mg/d AA-Ag was significantly influenced by aspirin 100 mg/d AA-Ag, BMI and platelet counts. The rate of gastrointestinal bleeding decreased from 12.00% to 5.00%,and upper gastrointestinal symptoms decreased from 59.00% to 21.00% after the switch in 40 mg/d group. Switching aspirin dosage from 100 mg/d to 40 mg/d reduces the bleeding events and improves upper gastrointestinal symptoms, thus inhibiting platelet aggregation effectively in very elderly patients.

The most complained gastrointestinal symptoms are chronic diarrhea, bloating and abdominal pain. Once malignancies and inflammatory bowel diseases are excluded, irritable bowel syndrome (IBS) and the so called "IBS-like disorders" should be taken into account. The relationship between IBS as defined by Rome IV criteria and these clinical conditions is sometimes obscure, since many IBS patients identify food as a possible trigger for their symptoms. Here, we discuss IBS and the most common IBS-like disorders (celiac disease, non-celiac gluten sensitivity, fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs), lactose intolerance, small intestinal bacterial overgrowth (SIBO), α-amylase/trypsin inhibitor (ATIs), nickel allergic contact mucositis), focusing on epidemiologic, clinical, diagnostic and therapeutic aspects. Given the lack of specificity of symptoms, clinical investigation will be facilitated by awareness of these disorders as well as new specific diagnostic tools.

Objective: One of the most common global disorders is related to gastrointestinal system. Functional dyspepsia (FD) defined as upper abdominal pain and discomfort in the absence of organic ailments is a prevalent disease without any confirmed medication. The purpose of this study was to find gastric disorders which might be coincidental to FD based on traditional Persian medicine (TPM). Materials and Methods: We searched the main textbooks of TPM including Al-Havi (by Rhazes), Canon of medicine (by Avicenna), ZakhireKhawrazmshahi (by Ismail Jorjani), Moalijat-e Aghili and Makhzan Al-adviya (by Mohammad Hosein AghiliShirazi), and ExirAzam (by Hakim Azam Khan). Also, we searched Pubmed, Scopus, Science Direct, Medline, scientific information database (SID), Iranmedex and Google Scholar from 1980 to 1 August 2014 for dyspepsia, gastrointestinal disease, traditional Persian medicine, and gastric dystemperaments. Results: There is no equivalent term for FD in traditional Persian medicine although similar signs and symptoms are visible in terms like simple cold dystemperament of stomach, indigestion, and digestion debility in TPM sources. Some treatments mentioned in TPM have shown promising results in the current experimental tests. Conclusion: Finding these similarities in complementary and alternative medicine (CAM) textbooks may lead to discovering new remedies for this widespread disease. PMID:27222829

Mastocytosis is a clonal neoplastic disorder of the mast cells (MC) that can be limited to the skin (cutaneous mastocytosis) or involve one or more extracutaneous organs (systemic mastocytosis). The clinical manifestations of mastocytosis are heterogeneous ranging from indolent disease with a long-term survival to a highly aggressive neoplasm with survival of about 6 mo. Although liver involvement in aggressive systemic mastocytosis (ASM) is relatively common, the development of portal hypertension with or without cirrhosis is rare. We report a case of ASM without skin involvement in a 72-year-old caucasian male who presented with non-cirrhotic portal hypertension based on clinical, analytical, imagiological and endoscopic findings. Given the hematological picture, the correct diagnosis was established based on ancillary tests for MC using bone marrow aspirates and biopsy. Extensive involvement of the liver and gastrointestinal tract was histologically documented. The disease progressed rapidly and severe pancytopenia and recurrent upper gastrointestinal bleeding became the dominant problem. This case illustrates the challenge in establishing a diagnosis of ASM especially when the clinical picture is atypical and without skin involvement. Gastroenterologists should consider infiltrative disease, particularly systemic mastocytosis, as a differential diagnosis in a clinical case of portal hypertension of unknown etiology.

Degos' disease: a distinctive pattern of disease, chiefly of lupus erythematosus, and not a specific disease per se.

Degos' disease, known confusingly as malignant strophic papularis, is an uncommon condition of unknown cause characterized by distinctive infarctive lesions in the skin, gastrointestinal tract, and central nervous system; the lesions at the two latter sites often result in death. We deem Degos' disease to be analogous to lupus erythematosus in the sense that each is fundamentally a systemic pathologic process involving several organs, among them the skin, but, moreover, we regard Degos' disease, in most instances, to be an actual manifestation of lupus erythematosus. Histopathologically, the findings in sections of tissue of skin lesions of Degos' disease are indistinguishable from those of one expression of cutaneous lupus erythematosus; immunopathologically, some patients with morphologic findings stereotypical of Degos' disease display signs characteristic of lupus erythematosus. For these reasons, we consider Degos' disease to be a distinctive pattern of disease, rather than a specific disease per se, just as are erythema multiforme, erythema nodosum, leukocytoclastic vasculitis, Sweet's syndrome, and pyoderma gangrenosum, to name but five of scores of them. The singular pattern that is designated Degos' disease usually is an expression of lupus erythematosus, but, episodically, of conditions like dermatomyositis and rheumatoid arthritis.

Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

The department of internal medicine of the military hospital of Gabon managed 92 cases of upper gastrointestinal bleeding from April 2009 to November 2011. The frequency of these hemorrhages in the department was 8.2%; they occurred most often in adults aged 30-40 years and 50-60 years, and mainly men (74%). Erosive-ulcerative lesions (65.2%) were the leading causes of hemorrhage, followed by esophageal varices (15.2%). These results underline the importance of preventive measures for the control of this bleeding.

This report describes a novel approach to endoscopically induce bleeding by removing a clot from the bleeding site during angiography for upper gastrointestinal (UGI) hemorrhage. This procedure enabled accurate identification of the bleeding site, allowing for successful targeted embolization despite a negative initial angiogram. Provocative endoscopy may be a feasible and useful option for angiography of obscure bleeding sites in patients with UGI arterial hemorrhage. Copyright © 2016 SIR. Published by Elsevier Inc.

Background The sites of origin, causes and outcomes of severe hematochezia have not been compared between cirrhotics and non-cirrhotics. In cirrhotics versus non-cirrhotics presenting with severe hematochezia, we aimed at (1) identifying the site and etiology of gastro-intestinal bleeding and independent predictors of bleeding from the upper gastrointestinal tract versus small bowel or the colon, (2) comparing 30-day clinical outcomes, and (3) proposing an algorithm for management of severe hematochezia. Methods In this cohort study from two university-based medical centers, 860 consecutive patients with severe hematochezia admitted from 1995 to 2011 were prospectively enrolled with 160 (18.6 %) cirrhotics. We studied (a) general clinical and laboratory characteristics of cirrhotics versus non-cirrhotics, (b) predictors of bleeding sites in each patient group by multiple variable regression analysis, and compared (c) 30-day outcomes, including rebleeding, surgery and deaths. Results Cirrhosis independently predicted an upper gastrointestinal source of bleeding (OR 3.47; 95 % CI 2.01–5.96) as well as history of hematemesis, melena in the past 30 days, positive nasogastric aspirate, prior upper gastrointestinal bleeding or use of aspirin or non-steroidal anti-inflammatory. The most prevalent diagnoses were esophageal varices (20 %) in cirrhotics and colon diverticular bleeding (27.1 %) in non-cirrhotics. Thirty-day rates of rebleeding, surgical interventions and deaths were 23.1 versus 15 % (P = 0.01), 14.4 versus 6.4 % (P < 0.001), and 17.5 versus 4.1 % (P < 0.001), in cirrhotics versus non-cirrhotics, respectively. Conclusions Cirrhosis predicted an upper gastrointestinal site of bleeding in patients presenting with severe hematochezia. The 30-day rates of rebleeding, surgery, and death were significantly higher in cirrhotics than in non-cirrhotics. PMID:27286877
