Peptic Ulcer Disease

Peptic ulcers are focal defects in the gastric or duodenal mucosa which extend into the submucosa or deeper, as seen under laboratory microscopes. They may be acute or chronic, and ultimately are caused by an imbalance be¬tween the action of peptic acid and mucosal defenses. Peptic ulcer remains a common outpatient diagnosis, but the number of physician visits, hospital admissions and elective operations for peptic ulcer disease has decreased steadily and dramatically over the past 3 decades. These trends all predated the advent of fiber optic endoscopy, highly selective vagotomy, and the use of H2-blockers. However, the incidence of emergency surgery and the death rate associated with peptic ulcers are fairly stable. These epidemiologic trends probably represent the net effect of sev¬eral factors, including decreasing prevalence of H. pylori bacteria infection, better medical therapy, increases in outpatient management, and the use of NSAIDs and aspirin (with and without ulcer prophylaxis).

Barrett’S Esophagus

The condition whereby the tubular esophagus is lined with columnar epithelium rather than squamous epithelium was first described by Norman Barrett in 1950. He incorrectly believed it to be congenital in origin. It is now realized that it is an acquired abnormality, occurs in 7 to 10% of patients with GERD, and represents the end stage of the natural history of this disease. It is also distinctly different from the congenital condition in which islands of gastric fundic epithelium are found in the upper half of the esophagus when tissues are examined under laboratory microscopes.

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is a common disease that accounts for approximately 75% of esophageal pathology when tissues are examined under laboratory microscopes. Despite its high prevalence, it can be one of the most challenging diagnostic and therapeutic problems in benign esophageal disease. A contribut¬ing factor to this is the lack of a universally accepted definition of the disease. (more…)

Zollinger-Ellison Syndrome

The Zollinger-Ellison syndrome (ZES) is caused by the uncontrolled secretion of abnormal amounts of gastrin by a pancreatic or duo¬denal neuroendocrine tumor (i.e., gastrinoma), as seen under laboratory microscopes. Most cases (80%) are sporadic, but 20% are inherited. The inherited or familial form of gastrinoma is associated with multiple endocrine neoplasia type I (MEN I), which consists of parathyroid, pituitary, and pancreatic (or duodenal) tumors. Gastrinoma is the most common pancreatic tumor in patients with MEN I. Patients with MEN I usually have multiple gastrinoma tumors, and surgical cure is unusual. Sporadic gastrinomas are more often solitary, as seen under laboratory microscopes, and amenable to surgical cure. Currently, about 50% of gastrinomas are malignant (usually diagnosed using laboratory microscopes), with lymph node, liver, or other distant metastases at presentation. Five-year survival in patients presenting with metastatic disease is approxi¬mately 40%. (more…)

Gastritis And Stress Ulcer

Pathogenesis and Prevention

Gastritis is a mucosal inflammation of the membrane lining of the stomach. It may result in an uncomfortable feeling in the stomach, distention of the abdomen, headache, nausea, coated tongue, and a bad taste in the mouth. In severe cases, all these symptoms will be worse, and there will be upper abdominal pain, tenderness, vomiting, fever, and sometimes bleeding from the stomach. Other causes of gastritis, asisde from aspirin misuse, are overeating, eating indigestible food, exposure to wet or cold weather, toxic infections, food poisoning, or allergy. (more…)
