A 28-year-old Caucasian man was admitted in our unit for acute massive rectal bleeding. Past medical and family history was unremarkable. Hemoglobin was 7.6 g/dL. Blood transfusions were required. Computed tomography and gastrointestinal endoscopy were negative for active bleeding. When patient's hemoglobin was normalized and stable, a video capsule endoscopy was performed. Video relieved the presence of multiple digiunal and ileal angiodysplastic lesions. A double endoscopic argon plasma coagulation procedure was planned on general anaesthesia...

This paper deals with the segmentation of angiodysplasias in wireless capsule endoscopy images. These lesions are the cause of almost 10% of all gastrointestinal bleeding episodes, and its detection using the available software presents low sensitivity. This work proposes an automatic selection of a ROI using an image segmentation module based on the MAP approach where an accelerated version of the EM algorithm is used to iteratively estimate the model parameters. Spatial context is modeled in the prior probability density function using Markov Random Fields...

BACKGROUND: For proper evaluation of capsule endoscopy (CE), a complete examination is necessary. AIM: We evaluated risk factors of an incomplete CE with focus on patient hospitalization. METHODS: We retrospectively evaluated 161 consecutive patients who underwent CE between 01.07.2013 and 13.03.2016. Main indications were active bleeding, iron deficiency anemia (IDA), inflammatory bowel disease (IBD), abdominal pain, and familial adenomatous polyposis (FAP)...

BACKGROUND: Capsule Endoscopy (CE) has become the first-line tool to identify an underlying etiology for Obscure Gastrointestinal Bleeding (OGIB) in the small bowel (SB). This study aims to investigate the long-term outcome of patients with a negative CE. METHODS: Retrospective review of standardized application forms of all patients who underwent CE for OGIB at the Ghent University Hospital between 2002 and 2013. Follow-up data on patients with a negative CE result (n=263) were collected by contacting the referring physician...

BACKGROUND AND OBJECTIVES: Red blood cell (RBC) transfusion may be justified in iron deficiency anaemia (IDA) when an increase in oxygen delivery is needed, as sometimes occurs in subjects with haemoglobin <8·0 mg/dL, serious comorbidities or at risk of cardiovascular instability. Earlier investigations showed that some patients with severe IDA requiring transfusion had lower than expected post-transfusion haemoglobin levels with poorer clinical outcomes than other patients. After hypothesizing that haemoglobin responses to transfusion were different and that the underlying gastrointestinal (GI) disorders causing IDA could be a confounder explaining this association, these responses were analysed in a prospective cohort of IDA adults referred for outpatient GI investigation...

BACKGROUND/AIMS: Videocapsule endoscopy (VCE) and double-balloon endoscopy (DBE) allow deep exploration in patients with suspected small bowel pathology. VCE is often performed as an initial small bowel examination to explore whether an intervention by DBE is indicated and to determine insertion route. The study aim was to evaluate the correlation between DBE and VCE in patients with obscure or overt bleeding or anemia, as well as intervention frequency, and complications. METHODS: Retrospective observational study...

BACKGROUND: Anemia is defined as hemoglobin below the cutoff of normal in studies examining the gastrointestinal (GI) tract in iron-deficiency anemia (IDA). Although the risk of GI cancer (GIC) increases as hemoglobin decreases, guidelines do not usually recommend hemoglobin thresholds for IDA investigation. METHODS: To elucidate whether underlying GI disorders explain the different hemoglobin values and clinical outcomes observed initially in IDA patients referred for GI workup, we prospectively investigated the diagnostic yield of a thorough GI examination in consecutive IDA adults with predefined hemoglobin <9g/dL and no extraintestinal bleeding...

BACKGROUND & AIM: Iron deficiency anemia (IDA) is associated with celiac disease (CD). Although gluten-free diet (GFD) is an efficient treatment for CD, IDA remains an occasional finding during follow-up and correlates to inadequate gluten exclusion. Little is known regarding persistent IDA despite effective GFD. We aimed to evaluate the role of small bowel capsule endoscopy (SBCE) in this setting. METHODS: We prospectively included consecutive patients undergoing GFD for ≥24 months with persistent concomitant IDA...

Protein arginine methyltransferase 1 (PRMT1) is involved in multiple cellular functions including proliferation and differentiation. Although PRMT1 is expressed in vascular endothelial cells (ECs), which are responsible for angiogenesis during embryonic development, its role has remained elusive. In this study, we generated endothelial-specific prmt1-knockout (Prmt1-ECKO) mice, and found that they died before embryonic day 15. The superficial temporal arteries in these embryos were poorly perfused with blood, and whole-mount 3D imaging revealed dilated and segmentalized luminal structures in Prmt1-ECKO fetuses in comparison with those of controls...

REVIEW
Christian S Jackson, Richard Strong
Gastrointestinal angiodysplasia (GIAD) are red flat arborized lesions that are found throughout the entire gastrointestinal tract. GIAD can vary in size and have a range of presentation from occult to life-threatening bleeding. The typical presentation is intermittent bleeding in the setting of iron deficiency anemia. Endoscopy is the primary means of diagnosis and endoscopic therapy is noted to be initially effective. However, rebleeding can be as high as 40% to 50% in patients with small bowel GIAD. This review describes the pathophysiology for the development of GIAD and the current roles of endoscopic, medical, and surgical therapy in its treatment...

INTRODUCTION: Gastrointestinal angiodysplasias are defined as vascular dilations that communicate capillaries and veins in the walls of the digestive tract. The clinical presentation of these lesions varies from chronic occult bleeding to severe gastrointestinal hemorrhage. AIM: The primary aim of our study was to analyze lesion location, the efficacy of therapeutic endoscopy with argon plasma coagulation, and the factors associated with rebleeding in patients with gastrointestinal angiodysplasias...

BACKGROUND & AIMS: Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is controversial. METHODS: Herein, we report the case of a 65-year-old female patient with a 'double Osler syndrome' consisting of hereditary haemorrhagic telangiectasia (HHT) and type I hereditary angioedema diagnosed at the age of 25 and 22 years respectively...

Klippel-Trenaunay syndrome is the most frequent systemic venous angiodysplasia. It is characterized by cutaneous capillary malformations - naevus flammeus, excessive growth of soft and bone tissue, venous and lymphatic malformations. Investigative methods include: clinical examinations, venography as the evidence of dysplastic changes of superficial and / or deep venous system, the Moyne obstruction and venous insufficiency perforator. Treatment is conservative, related to that of chronic venous disease. The surgery is aimed at removing the varices and insufficient perforators (Fig...

Biliary angiodysplasia is extremely rare. Our background search revealed only a few case reports in the English literature. We present a case of angiodysplasia of the proximal common bile duct in a patient with subacute upper gastrointestinal bleeding and symptomatic anemia. A standard esophagogastroduodenoscopy with subsequent dedicated duodenoscopy revealed blood-stained bile draining from the major ampulla orifice. A contrast-enhanced magnetic resonance cholangiopancreatography was unrevealing for any pancreaticobiliary pathology...

Patients with a left ventricular assist device (LVAD) have increased risk of gastrointestinal (GI) bleeding. They are prone to develop angiodysplasia of the small intestine, and have a higher risk of bleeding as these patients are all required to be on permanent therapeutic anticoagulation. Here we report a case of a critically ill 55-year-old male on pressors and inotropes with an LVAD, who successfully underwent an antegrade double balloon enteroscopy (DBE).

BACKGROUND: Inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease are diseases with impaired epithelial barrier function. We aimed to investigate whether mutated prostasin and thus, reduced colonic epithelial sodium channel activity predisposes to develop an experimentally dextran sodium sulfate (DSS)-induced colitis. METHODS: Wildtype, heterozygous (fr/+), and homozygous (fr/fr) prostasin-mutant rats were treated 7 days with DSS followed by 7 days of recovery and analyzed with respect to histology, clinicopathological parameters, inflammatory marker mRNA transcript expression, and sodium transporter protein expression...

INTRODUCTION: Gastrointestinal angiodysplasias are an important cause of difficult-to-manage bleeding, especially in older patients. Endoscopic coagulation of angiodysplasias is the mainstay of treatment, but may be difficult for small bowel angiodysplasias because of the inability to reach them for endoscopic intervention. Some patients are red blood cell (RBC) transfusion dependent due to frequent rebleeding despite endoscopic treatment. In small cohort studies, octreotide appears to decrease the number of bleeding episodes in patients with RBC transfusion dependency due to gastrointestinal angiodysplasias...
