Bezoar is a mass formed by indigested materials. They are a rare cause of intestinal obstruction. They are most frequently located in stomach. Incidence of bezoar located in duodenum is very rare. We report a case of 47-year-old male patient who suffered from gastric outlet obstruction due to a bezoar located in duodenum.

Breast cancer metastasizes to the gastrointestinal (GI) tract are exceedingly rare. The low incidence and vague presentation of GI metastasizes often cause delay in diagnosis and treatment. Here, we present a case of metastatic breast cancer causing gastric outlet obstruction and rectal obstruction.

BACKGROUND & AIMS Secretory diarrhea is caused by inhibition of intestinal active sodium absorption and stimulation of active chloride secretion. The resulting increase in fecal sodium salts causes an isotonic increase in fecal water output. Abnormalities in potassium transport are not known to be a cause of secretory diarrhea. The aim of our report is to describe a patient with secretory diarr...

BACKGROUND Stent palliation is the gold standard for gastric/duodenal cancer outlet obstruction. When stenting is impossible, feeding may be achieved through a gastrojejunostomy (PEG-J), but displacement of jejunal tube is frequent due to manipulation for feeding and drainage. Gastric outlet obstruction results on increased gastroesophageal reflux or extra-tube leakage. In order to reduce the j...

OBJECTIVES To develop a noninvasive method to measure urinary flow rate in the mouse. This could be useful for the study of bladder outlet obstruction, as well as processes affecting detrusor function in the awake animal. Genetically engineered mice can improve our understanding of a variety of human bladder diseases. METHODS A metabolic cage without a fecal separation screen was placed above...

Studies were undertaken to assess expression of inducible cyclooxygenase (COX)-2 in bladder during fetal development and COX-1 and COX-2 expression after outlet obstruction. Bladder tissue or bladder progenitor tissue was harvested from CD-1 murine embryos at embryonic days 11.5( E11.5), E14.5, E17.5, E20.5 (newborn), and from adult. Bladder obstruction was created in adult female mice by ligat...

ABSENCE of the pulmonic valve is a rare congenital lesion which is usually associated with tetralogy of Fallot." 2 We have recently observed a patient in whom this anomaly coexisted with "double-outlet right ventricle." This case is reported because a review of the literature has failed to reveal a similar case and because certain difficulties inherent in the differentiation of double-outlet ri...

TO THE EDITOR: In addition to motor signs, patients with Parkinson’s disease (PD) suffer from a variable degree of autonomic impairment. Constipation is one of the most common autonomic dysfunctions observed in PD and may precede the onset of motor signs by many years (1). Chronic constipation, defined as the occurrence of less than three bowel movements per week accompanied by straining at sto...
