Gastrectomy requires coordinated care from various medical specialists and departments to ensure comprehensive treatment and optimal outcomes for patients.

• Surgeons: General surgeons or surgical oncologists are the primary specialists who perform gastrectomy. These surgeons have specialised training in abdominal surgery and oncology, enabling them to skillfully remove all or part of the stomach while minimising risks and preserving surrounding organs and tissues. They are responsible for planning the surgical approach, performing the operation with precision, and ensuring proper postoperative care.
  
• Surgical Oncologists: For cases involving stomach cancer, surgical oncologists play a crucial role in determining the extent of the cancer and planning the surgical approach accordingly. They work closely with other oncology specialists to develop a comprehensive treatment plan that may include surgery, chemotherapy, and radiation therapy.
• Gastroenterologists: Gastroenterologists may be involved in the initial diagnosis of stomach conditions that require gastrectomy, such as severe ulcers, gastrointestinal stromal tumours (GISTs), or other non-cancerous lesions. They perform diagnostic procedures like gastroscopy (endoscopy) to visualise and biopsy suspicious areas in the stomach lining
• Oncologists: Medical oncologists collaborate with surgical oncologists to determine the need for adjuvant therapy (chemotherapy or targeted therapy) before or after gastrectomy, particularly for cases of stomach cancer. They oversee systemic treatments aimed at eliminating residual cancer cells and reducing the risk of cancer recurrence.

The collaborative efforts of these medical professionals and departments are essential in providing comprehensive care to patients undergoing gastrectomy.
