Tc-99m labeled RBC scintigraphy is commonly employed in the evaluation of acute gastrointestinal bleeding. On Tc-99m RBC studies gastrointestinal bleeding is seen as an initial focus of increased radiotracer activity that on subsequent images increases in intensity and changes position in a pattern that conforms to segments of bowel. We report a case of a patient with multiple episodes of hemat...

BACKGROUND AND STUDY AIMS The small intestine is a potential origin of bleeding in patients with unexplained gastrointestinal tract hemorrhage or iron-deficiency anemia. Most reports on the investigation of these patients describe the use of upper tract enteroscopy. The diagnostic yield of combined upper and lower enteroscopy has not been widely assessed and remains to be clarified. The aim of ...

The recently introduced new oral anticoagulants (nOAC) carry a higher gastrointestinal bleeding risk compared to traditional antithrombotic therapy. Current diagnostic coagulation tests are not accurate enough to determine the level of coagulopathy. Besides that, the lack of a specific antidote leaves the endoscopist unsure how to achieve hemostasis during gastrointestinal hemorrhage. In this b...

Vascular malformations of the small bowel are uncommon, yet remain a cause of gastrointestinal bleeding in up to 5% of patients with gastrointestinal hemorrhage. The diagnosis of these lesions is suspected in patients with a gastrointestinal source of blood loss with a negative upper endoscopy and colonoscopy. Enteroscopy remains the mainstay in diagnosing these lesions. Therapeutic options inc...

Acute massive hemorrhage from CD occurred in 3.0% in our institution. Forty CD patients with massive hemorrhage were reported in last 20 years in Japan. The ratio of male to female was 7.0. Ninety percent of them complicated the small intestinal CD. Massive bleeding was seen mostly in the ileum (82.5%) and next was in the colon (12.5%). However massive gastrointestinal hemorrhage is not often c...

Lower gastrointestinal bleeding is a common disease among elderly patients. The common sources of lower gastrointestinal bleeding include vascular disease, Crohn's disease, neoplasms, inflammatory bowel disease, hemorrhoids, and ischemic colitis. Lower gastrointestinal bleeding arising from the appendix is an extremely rare condition. We report a case of appendiceal hemorrhage in a young male. ...

Excessive bleeding is a major concern during the administration of thrombolytic therapy. Although the great majority of these events occur at sites of vascular interruption, major gastrointestinal, retroperitoneal, genitourinary, and central nervous system hemorrhage are known to occur. We present a patient who developed spontaneous pulmonary hemorrhage during thrombolytic therapy. Lack of reco...

Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. Hemorrhage occurs through mucosal erosion from an abnormally dilated submucosal artery. Although Dieulafoy's lesion is usually located in the stomach, it may occur anywhere in the gastrointestinal tract. We report here on a case of jejunal Dieulafoy's lesion presenting as a mass and short segment stricture on CT and enterocly...

INTRODUCTION Testicular neoplasms metastasizing to the retroperitoneum rarely involve the upper gastrointestinal tract. Gastrointestinal tract metastases usually present with complications including intestinal obstruction, gastrointestinal hemorrhage, and rarely ulceration of the bowel mucosa. CASE PRESENTATION We describe an unusual case of duodenal perforation as the presenting manifestatio...
