BACKGROUND Small bowel tumors comprise 25% of gastrointestinal (GI) neoplasms, of which only between 0.2 and 1% correspond to gastrointestinal stromal tumors (GIST). GI bleeding is the most common presentation of GIST, being responsible in 1% of the cases. This type of neoplasm can also be the origin of an intussusception, which is an infrequent process during adult age, representing only 5% of...

Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are al...

Introduction: Lipomas of the intestinal tract are rare, but they present as the third most common cause of intestinal neoplasms. Most intestinal lipomas are asymptomatic. However, they may present with bleeding, obstruction, intussusception, or abdominal pain. Spontaneous expulsion of an intestinal lipoma is extremely rare and has never been reported in the postoperative period. Case Descriptio...

The small intestine is an uncommon site of gastro-intestinal (GI) bleeding; however it is the commonest cause of obscure GI bleeding. It may require multiple blood transfusions, diagnostic procedures and repeated hospitalizations. Angiodysplasia is the commonest cause of obscure GI bleeding, particularly in the elderly. Inflammatory lesions and tumours are the usual causes of small intestinal b...

Physical exercise has been related with both beneficial effects on the gastrointestinal tract as with adverse effects on the latter. Gastrointestinal bleeding is one of these. In general, gastrointestinal bleeding is transient and mild. However, some cases caused by intestinal ischemia can sometimes be more serious due to the amount of bleeding and the presence of mucosal lesions. We present th...

Tuberculosis (TB) and HIV are considered pandemic by the World Health Organization (WHO). It has been reported that HIV infection is one of the major risk factors for the development of TB, increasing the incidence by up to 1,000 times, but it often has an atypical presentation. The incidence of extrapulmonary TB is increasing, largely among HIV patients. The diagnosis of intestinal TB is a cha...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to treat a number of conditions, and proton pump inhibitors (PPIs) are often used to prevent NSAID-induced gastric mucosal damage; however, the effects of NSAIDs on intestinal motility are poorly understood. The purpose of the present study is to determine the effects of a prototypical NSAID, indomethacin, either alone or in conjunct...

BACKGROUND AND AIMS There are limited data concerning the clinical outcome of patients with obscure gastrointestinal bleeding (OGIB) after double-balloon endoscopy (DBE). The aim of the present study was to evaluate the long-term outcome of patients with OGIB after DBE. PATIENTS AND METHODS Eighty-seven consecutive patients with OGIB (47 men and 40 women; mean age 65.3 years) underwent DBE be...

Small bowel metastases due to lung cancer are extremely rare and predominantly cause intestinal obstruction, perforation gastrointestinal bleeding. We report the case of a 51-year-old man diagnosed with pulmonary sarcomatoid carcinoma which an ileal mass was subsequently removed found be compatible localization carcinoma.
