Dieulafoy lesion is a vascular anomaly predominantly found in the stomach, which represents a rare cause of gastrointestinal bleeding and life-threatening haemorrhages in pediatric age with few cases reported in the literature. We experienced a 7-year-old previously healthy boy with hematemesis endoscopically diagnosed and successfully treated for a Dieulafoy lesion in the stomach. This case re...

A 66-year-old man presented with fatigue and acute upper gastrointestinal bleeding (hemoglobin 92g/L). He had melena but no signs of hematemesis. Upper gastrointestinal endoscopy revealed a 35×15-mm large polypoid lesion with multiple ulcerations in the second part of the duodenum (●" Fig.1). No biopsy samples were taken due to the risk of bleeding. The diagnosis was unclear and the patient und...

Upper gastrointestinal bleeding secondary to ulcer disease is common and results in substantial patient morbidity and medical expense. After initial resuscitation to stabilize the patient, carefully performed endoscopy provides an accurate diagnosis and identifies high-risk ulcer patients who are likely to rebleed with medical therapy alone and will benefit most from endoscopic hemostasis. For ...

Gastrointestinal disturbances like anorexia, nausea, vomiting, abdominal discomfort and diarrhoea are known adverse effects of rifampicin. We report an upper gastrointestinal bleeding due to haemorrhagic gastric erosions after ingestion of rifampicin for pulmonary tuberculosis. The cause and effect relationship between development of haemorrhagic gastric erosions and rifampicin administration w...

Various strategies can be used in the diagnosis of upper gastrointestinal tract bleeding. This study investigates the relevance of anamnestic and clinical findings for the diagnosis of the bleeding source. The authors introduced a computer-aided diagnostic system using Bayes’ theorem and compared it with clinicians’ predictions using anamnestic and clinical findings only. There was no differenc...

Gastrointestinal stromal tumors (GIST) are rare neoplasms that mostly affect patients over the age of 50, with no gender predilection1,2. The diagnosis of GIST is made by means of immunohistochemistry testing for CD117 (c-kit), and combination treatment with surgical intervention and adjuvant chemotherapy has produced good outcomes3. We report a case of gastric GIST diagnosed after an episode o...

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 manageme...

A 74-year-old man with a left-ventricular assist device (LVAD) as destination therapy for end-stage ischemic cardiomyopathy presented with acute upper gastrointestinal bleeding. Other symptoms included chronic early satiety, intermittent nausea, and non-specific abdominal discomfort since LVAD implantation 3 years ago. An actively bleeding duodenal arteriovenous malformation was successfully tr...

AIM To investigate the feasibility of a single-use endoscopy as an alternative procedure to nasogastric lavage in patients with acute gastrointestinal (GI) bleeding. METHODS Patients who presented with hematemesis, melena or hematochezia were enrolled in this study. EG scan™ and conventional esophagogastroduodenoscopy (EGD) were subsequently performed. Active bleeding was defined as blood in ...
