Dumping syndrome is a condition that can develop after surgery to remove all or part of your stomach or after surgery to bypass your stomach to help you lose weight. Also called rapid gastric emptying, dumping syndrome occurs when food, especially sugar, moves from your stomach into your small bowel too quickly.

Changes might include eating smaller meals and limiting high-sugar foods. In more-serious cases o

An ileostomy is an opening in the belly (abdominal wall) that’s made during surgery. The end of the ileum (the lowest part of the small intestine) is brought through this opening to form a stoma, usually on the lower right side of the abdomen. A Wound Ostomy Continence nurse (WOCN or WOC nurse) or the surgeon will figure out the best location for your stoma. (A WOC nurse is a specially trained registered nurse who takes care of and teaches ostomy patients. This nurse may also be called an ostomy nurse.)

This animated video is an informative video that provides information regarding Upper Gastro-intestinal Endoscopy. An upper GI endoscopy procedure allows your doctor to view the mucus lining of the upper portion of your gastro-intestinal tract. This includes your oesophagus, stomach and duodenum. Upper endoscopy is used to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, bleeding, or difficulty in swallowing. The procedure is performed using an endoscope which is a long thin flexible tube a light and a tiny video camera attached to the end. The camera transmits the image to a monitor. Uncomplicated upper endoscopy takes 10-20 minutes, your doctor will gently insert the endoscope through your mouth and then slowly and carefully move it down your oesophagus until it reaches your stomach. An endoscopy for stomach may also be necessary in some cases.

Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.
