Oesophagectomy is typically performed to treat esophageal cancer. Stomach cancer is frequently treated with a gastrectomy. There are two different types of operations: open gastrectomy, which involves making a huge cut in your stomach or chest, and keyhole surgery (laparoscopic gastrectomy), which involves making multiple smaller cuts and using specialised devices. A colectomy is a form of surgery used to treat conditions of the colon, including diverticulitis, inflammatory disease, and cancer.
