Esophageal / stomach cancer surgery
Stomach and Esophageal cancers are the lower in incidence but accord nevertheless. Patients diagnosed with stomach cancer often first notice a general discomfort in the stomach, loss of appetite, weight loss and vomiting. Patients diagnosed with oesophagal cancer start with concerns about difficulty or pain during swallowing, weight loss, or a cough and hoarseness.
Diagnosis of the stomach and oesophageal cancers are done by screening. Screening is generally done with a procedure called an upper endoscopy. While the patient is anaesthetized, the doctor inserts a flexible tube with a miniature camera down the oesophagus, viewing all areas of the upper part gastrointestinal (GI) tract: the oesophagus, the stomach and the duodenum, the first section of the small intestine. If cancer is revealed, the next test is for levels of advancement and may include Endoscopic ultrasound examination, CT or PET Scan, Bronchoscopy and Laparoscopy.
Treatment of both these types on cancer may be a combination of
- Radiation and
Surgery may be necessary to remove cancerous tissue, as well as nearby noncancerous tissue. The most common operation for stomach cancer is called gastrectomy. If part of the stomach is removed, it is called a subtotal or partial gastrectomy. If the entire stomach is removed, it is called a total gastrectomy.
Esophageal cancer surgery may be of two types. In one type of surgery, part of the Esophageal and nearby lymph nodes are removed, and the remaining portion of the oesophagus is reconnected to the stomach. In the other surgery, part of the Esophageal, nearby lymph nodes, and the top of the stomach are removed. The remaining portion of the Esophageal is then reconnected to the stomach.
Radiation therapy is the use of high-energy radiation to kill cancer cells and to shrink tumours. Chemotherapy is the use of anticancer drugs to treat cancerous cells. In most cases, chemotherapy works by interfering with the cancer cell’s ability to grow or reproduce.
Peroral Endoscopic Myotomy (POEM) is the latest innovation where the doctors carry out treatment for some common conditions known as Achalasia Cardia where the muscles of the food pipe become tighter, leading to difficulties in swallowing, which helps in reducing the duration of stay in hospital, reducing the costs and is less invasive. About 10-15 cases of this nature have been done in the last one year. This technology can be used to remove early tumours of the gastrointestinal tract.
