Esophagectomy — Oesophageal Resection Surgery

An esophagectomy is a complex operative intervention designed to resect diseased segments of the oesophagus—the muscular conduit transporting food and liquids from the pharynx to the stomach. The surgeon removes the primary tumour with clear microscopic margins, resects regional lymph node basins (lymphadenectomy), and reconstructs the digestive continuity, most commonly by mobilising and reshaping the stomach into an internal gastric tube pulled up into the chest or neck.

The procedure can be performed via open surgery (such as Ivor Lewis or McKeown approaches) using incisions in the abdomen, chest, or neck, or through minimally invasive and robotic-assisted techniques. Surgical approach depends on tumour location, stage, and the patient's individual anatomy.

For patients with resectable oesophageal cancer, an esophagectomy offers the best opportunity for long-term disease control or cure. Because it significantly alters gastrointestinal anatomy, understanding the procedure helps patients prepare for substantial recovery phases, temporary feeding tubes, and permanent dietary adaptations such as eating smaller, more frequent meals. Pathological assessment of the resected tissue also provides crucial information regarding clear margins and nodal involvement, informing subsequent surveillance or adjuvant treatment plans.

Before deciding on an esophagectomy, teams confirm diagnosis and stage through upper endoscopy (gastroscopy) with biopsy, endoscopic ultrasound (EUS) to assess wall invasion depth, and high-resolution CT or PET-CT scans to ensure absence of distant metastases. Comprehensive cardiopulmonary exercise testing and nutritional assessments are also performed to evaluate whether the patient can safely tolerate this major operation.

Esophagectomy is primarily performed for oesophageal cancers, including adenocarcinoma (frequently located at the gastro-oesophageal junction and linked to Barrett's oesophagus) and squamous cell carcinoma (often found in the middle or upper sections). It is also utilised for severe Barrett's oesophagus with high-grade dysplasia that cannot be resolved with endoscopic therapies.

Esophagectomy is frequently integrated into multimodal treatment plans rather than performed alone. Patients with locally advanced disease commonly undergo neoadjuvant chemoradiation (such as the CROSS regimen) or perioperative chemotherapy prior to surgery to shrink the tumour and eradicate micrometastases. Post-surgical pathology results determine whether further adjuvant therapies, including targeted immunotherapy, are necessary to reduce the risk of cancer recurrence.
