Gastrectomies are surgeries to remove part or all of the stomach. Gastrectomies are used to treat conditions such as stomach cancer.

Laparoscopic subtotal or total gastrectomy is a minimally invasive surgical procedure performed to treat stomach cancer. This advanced technique involves removing part or all of the stomach, depending on the extent of the cancer. The small bowel is anastomosed to healthy remnant stomach or oesophagus in the abdomen or chest to allow patients to be able to eat. The aim of the surgery is to eliminate cancerous tissue within the stomach.

The procedure is typically recommended for patients with stomach cancer, where cancerous cells are primarily confined to the stomach and have not spread extensively to other organs. The goal is to remove the affected tissue and restore normal digestive function.

During laparoscopic gastrectomy, the surgeon makes several small incisions in the abdomen. A thin, flexible tube with a camera (laparoscope) is inserted through one of the incisions, allowing the surgeon to view the surgical area on a screen. Specialised instruments are used to remove the necessary portion of the stomach, after which the remaining parts are reconnected to maintain digestive continuity.
