Peptic vs Gastric Ulcer
Peptic ulcerincludes all ulcers occurring in thestomachandduodenum. Gastric ulcer is a type of peptic ulcer. There are two types of peptic ulcer. They are gastric ulcer and duodenal ulcer. There is much confusion in the proper usage of the terms peptic, gastric and duodenal ulcers. Duodenal ulcers are more commonly known as peptic ulcers. Gastric ulcers are called by the same name usually. There are certain similarities between the two entities. Gastric and peptic ulcers present the same, with upper abdominal burning pain,indigestion,胸痛, sweating. They can present as black, tarry stools due to bleeding from an ulcer. Both conditions are associated withstress, irregular dietary habits, excessive secretion of gastric juices, and Helicobacter pylori. Upper gastrointestinalendoscopyto visualize the alimentary canal up to the second part of the duodenum is the investigation of choice in both conditions. A small piece of the ulcer edge may be removed to examine under the microscope, to excludecancers. Helicobacter pylori are associated with thechronic gastritis. Helicobacter pylori eradication treatment, antacids, and proton pump inhibitors are the available treatment options.
胃溃疡may occur due to excessive secretion of gastric juices combined with irregular dietary habits. There are three main meals of the day with two small snacks after breakfast and after lunch. Human body is conditioned to this regular regimen and gastric juices flow like clockwork at meal times even if nothing is in the stomach. Gastric juices help digest food. Secretion of gastric juices occurs in three phases. Cephalic phase starts when we feel hungry and when we see food. When we start eating the gastric phase starts and when food enters the small bowel the intestinal phase starts. When there is nothing in the stomach for the acidic stomach juices to act upon, the mucosal lining becomes its target. There are many protective mechanisms in the stomach to protect it against the highly acidic secretions. There is a thickmucuslayer overlying the gastric lining cells. The acidity drops along the thickness of the mucus layer from highly acidic stomach cavity to a neutralpH在胃内衬细胞上。有许多缓冲液可以停用任何流浪酸。当有长期存在的饥饿或不规则/不足的食物摄入量时，这些保护机制就会失败。没有这种保护，酸会破坏胃衬细胞，溃疡可能是最终结果。胃溃疡通常发生在较小和更大的曲率和胃的幽门区域。由于胃酸性不断刺激，这些溃疡很难治疗。食物也可能会回流食管with chronic gastritis. With prolonged gastritis, the lining of the lower esophagus may change into a pre-cancer state. This is calledBarette’s esophagus.
Duodenal ulcer, more commonly known as peptic ulcer, can occur anywhere in the duodenum but are more common down to the second part of the duodenum. Duodenal ulcers are also due to failure of the protective mechanisms of the duodenal lining. In the duodenum, there is additional irritation due to pancreatic juices. Once the protective mechanisms fail, the protein digesting enzymes in the pancreatic juice damage the duodenal lining. Helicobacter pylori play a major role in duodenal ulcers, as well. Well known life threatening complication of duodenal ulcers is torrential bleeding from the eroded gastro-duodenal artery.
胃溃疡和消化性溃疡有什么区别？
•胃溃疡发生在the stomach while peptic ulcer occurs in the duodenum.
•胃溃疡疼痛在饭前更多，而十二指肠溃疡疼痛在饭后更多。
