Surgical removal of all or part of the stomach; it is usually done to stop hemorrhage from an ulcer or to remove a chronic ulcer or cancer.
A partial gastrectomy is the removal of part of the stomach, and a total gastrectomy is the removal of the entire stomach. A partial removal is most commonly performed to treat non- cancerous stomach or duodenal ulcers, as well as stomach cancer that is low in the stomach near the duodenum. A total gastrectomy is required in some cases of stomach cancer and when ulcers that fail to respond to nonsurgical treatment bleed uncontrollably or perforate the stomach wall. The advent of new medical treatments for ulcer disease has made gastrectomy for ulcers far less common.
A surgical operation in which the whole or a part of the stomach is removed. Total gastrectomy, in which the esophagus is joined to the duodenum, is usually performed for stomach cancer but occasionally for the Zollinger-Ellison syndrome. In partial (or subtotal) gastrectomy the upper third or half of the stomach is joined to the duodenum or small intestine (gastroenterostomy): an operation usually carried out in severe cases of peptic ulcers. After gastrectomy capacity for food is reduced, sometimes leading to weight loss. Other complications of gastrectomy include ‘dumping syndrome, anemia, and ‘malabsorption.
A major operation to remove the whole or part of the stomach. Total gastrectomy is a rarely performed operation, usually for cancer of the stomach; the oesphagus is then connected to the duodenum. Partial gastrectomy is sometimes still done if a patient with a peptic ulcer has failed to respond to treatment with H,-blocking drugs along with antibiotics to combat Helicobacter pylor. Partial gastrectomy is usually accompanied by vagotomy, which involves cutting the vagus nerve controlling acid secretion in the stomach.
Total gastrectomy refers to the surgical removal of the entire stomach, often performed as a treatment for certain types of stomach cancer. Partial gastrectomy, on the other hand, involves excising only a portion of the stomach. This used to be a common procedure for treating peptic ulcers, which are ulcers in the stomach or duodenum. However, it has been largely supplanted by pharmacological treatments.
Following a gastrectomy, an individual may encounter sensations of fullness and discomfort post meals. There could be several post-surgical complications such as regurgitation or vomiting of bile that might cause inflammation in the stomach or esophagus; diarrhea; and dumping syndrome, which is characterized by symptoms like sweating, nausea, dizziness, and weakness post meals, due to food exiting the stomach too rapidly. Another potential complication is malabsorption, signifying a diminished capacity to absorb nutrients, possibly leading to conditions like anemia or osteoporosis, which is characterized by a loss of bone density. After undergoing a total gastrectomy, patients are unable to absorb vitamin B12 and require lifelong vitamin injections.
