Gastrectomy (from ancient Greek γαστήρ - stomach and ἐκτομή - “removal”, literally “removal of the stomach”), or wide resection of the stomach - a surgical operation to remove a large or even the entire stomach along with 75% or more of the stomach; as a rule, it is carried out as a stage in the treatment of malignant neoplasms of the stomach and esophagus. Transthoracic - south of the main trunk in the abdomen. This approach to surgery allows for a less invasive procedure for some types of stomach cancer. These include gastrectomy or subtotal gastrectomy or distal subtotal (arm) cutting. Other surgeries to remove carcinoma are gastrectomy (for one-stage treatment) and gastrectomy combined with complete radiation therapy.
