Gastrectomy
Removing part (subtotal) or all (total) of the stomach for stomach cancer, with the bowel joined to what remains.
Curative surgery for localised gastric cancer, combined with D2 lymphadenectomy and perioperative FLOT chemotherapy in the West or adjuvant chemotherapy in East Asia, where screening finds earlier disease and endoscopic resection cures many mucosal tumours. Laparoscopic and robotic approaches are standard in Korea and Japan (KLASS, JCOG trials). Consequences include small-meal eating, dumping, vitamin B12 deficiency and weight loss, hence the drive to avoid palliative gastrectomy in metastatic disease.
