Gastrectomy is a surgical procedure to remove all or part of the stomach. The specific procedures involved depend on whether a partial or total gastrectomy is performed. Partial Gastrectomy: 1. Incision: An incision is made in the abdomen to access the stomach. 2. Tumor/Disease Identification: The diseased or cancerous part of the stomach is identified. 3. Resection: The affected portion of the stomach is surgically removed. 4. Reconstruction: The remaining parts of the digestive tract (usually the small intestine) are reconnected to the remaining stomach or directly to the esophagus to allow for the passage of food. This is often a Billroth I (stomach to duodenum) or Billroth II (stomach to jejunum) reconstruction. Total Gastrectomy: 1. Incision: Similar abdominal incision. 2. Stomach Removal: The entire stomach is removed. 3. Reconstruction: The esophagus is then directly connected to the small intestine (usually the jejunum) to create a new pathway for food to travel from the esophagus to the intestines. This is typically an esophagojejunostomy. In both procedures, surgeons aim to remove all diseased tissue while preserving as much healthy digestive function as possible. What's next?
