Oesophageal Cancer Surgery

What is Oesophageal Cancer Surgery?

Oesophageal cancer surgery is a procedure performed to remove cancerous tissue from the oesophagus, the muscular tube that carries food from the mouth to the stomach. The primary goal of surgery is to completely remove the tumour along with nearby lymph nodes to prevent the cancer from spreading and to improve the chances of long-term survival.

Who is Suitable for Oesophageal Cancer Surgery?

Not every patient with oesophageal cancer will benefit from surgery. Doctors carefully assess each individual to determine whether surgery is the most appropriate treatment option.

Patients who are most suitable for oesophageal cancer surgery typically include those whose cancer:

• Is confined to the oesophagus or nearby lymph nodes: Surgery is most effective when the tumour has not spread to distant organs such as the liver, lungs, or bones.
• Is diagnosed at an early or locally advanced stage: Patients with stage I, II, or selected stage III cancers may benefit from surgery as part of their treatment plan.
• Can be completely removed: Imaging tests such as CT scans, PET scans, and endoscopic ultrasound help surgeons determine whether the tumour can be safely removed.
• Have adequate physical health: Because oesophageal surgery is a major surgery, patients need to be healthy enough to tolerate the procedure and recovery process.
• Have good lung and heart function: Pre-operative testing evaluates whether the body can handle anaesthesia and the demands of surgery.
• Can benefit from combined treatments: Many patients receive chemotherapy or chemoradiotherapy before surgery to improve surgical outcomes.

Age alone does not automatically exclude someone from surgery. Many older patients can still undergo oesophageal cancer surgery if they are otherwise healthy and medically fit. Conversely, some younger patients with serious medical conditions may not be suitable candidates.

Benefits of Oesophageal Cancer Surgery

When oesophageal cancer is detected early or has not spread extensively, surgery can provide significant benefits.

• Potential for cancer cure: Removing the tumour completely offers the best chance of eliminating the disease.
• Improved long-term survival: Patients whose cancer is successfully removed may live significantly longer compared with those treated with non-surgical therapies alone.
• Removal of affected lymph nodes: Surgery allows doctors to remove and analyse nearby lymph nodes to assess whether cancer has spread.
• Accurate cancer staging: Examining the removed tissue helps determine the exact stage of the cancer and guides further treatment decisions.
• Relief of swallowing difficulties: Some patients experience severe difficulty swallowing due to tumour obstruction. Removing the tumour may restore the ability to eat and drink more comfortably.
• Better outcomes with combined treatments: Surgery combined with chemotherapy or radiotherapy can significantly improve survival rates in suitable patients.

Advances in surgical techniques, anaesthesia, and postoperative care have improved outcomes and reduced complication rates in recent years. Specialised centres with experienced oesophageal surgeons generally achieve the best results.

Types of Oesophageal Cancer Surgery

Several different surgical techniques can be used to treat oesophageal cancer. The choice of procedure depends on the tumour’s location, stage, and the patient’s overall health.

• Ivor Lewis Oesophagectomy: This is one of the most commonly performed procedures. The surgeon removes the diseased part of the oesophagus through incisions in the abdomen and chest, then reconnects the stomach to the remaining oesophagus.
• Transhiatal Oesophagectomy: The oesophagus is removed through incisions in the abdomen and neck without opening the chest. This approach may be used for cancers located in the lower oesophagus.
• Three-Stage (McKeown) Oesophagectomy: This technique involves incisions in the abdomen, chest, and neck. It allows surgeons to remove more of the oesophagus and create the connection in the neck.
• Minimally Invasive Oesophagectomy (MIE): Surgeons use laparoscopic or robotic instruments through small incisions. This method may reduce pain, complications, and hospital stay while achieving the same cancer-removal outcomes.
• Endoscopic Resection: For very early cancers, surgeons may remove abnormal tissue through an endoscope inserted through the mouth without major surgery.

Alternative Options to Oesophageal Cancer Surgery

Surgery is not always the most appropriate treatment for oesophageal cancer. In some cases, alternative treatments may be recommended instead of surgery or in addition to it.

• Chemotherapy: Anti-cancer drugs may be used to shrink tumours, slow cancer growth, or treat cancer that has spread.
• Radiotherapy: High-energy radiation can destroy cancer cells and reduce tumour size.
• Chemoradiotherapy: A combination of chemotherapy and radiotherapy may be used as a primary treatment for some patients who cannot undergo surgery.
• Endoscopic therapies: Procedures such as endoscopic mucosal resection or radiofrequency ablation may treat very early cancers without removing the oesophagus.
• Oesophageal stenting: A metal or plastic tube may be placed in the oesophagus to keep it open and improve swallowing in patients with advanced cancer.
• Palliative care treatments: In advanced cases, treatment may focus on symptom relief, improving swallowing, and maintaining quality of life.

Preparation Before an Oesophageal Cancer Surgery

Before surgery, patients undergo a series of medical assessments to ensure they are fit for the procedure and to help the surgical team plan the most effective treatment.

Doctors usually begin with detailed imaging and diagnostic tests. These may include CT scans, PET scans, endoscopy, and endoscopic ultrasound to determine the size, location, and stage of the cancer. These tests help confirm whether the tumour can be safely removed and whether other treatments are needed before surgery.

Many patients receive neoadjuvant therapy, which means chemotherapy or combined chemotherapy and radiotherapy before surgery. This treatment aims to shrink the tumour, improve the likelihood of complete removal, and increase long-term survival.

An anaesthetist and surgical team also assess patients to evaluate heart and lung function. Because oesophageal surgery affects breathing and digestion, doctors may order lung function tests, blood tests, and cardiac assessments.

Patients can also help prepare themselves for surgery by improving their general health.

• Stop smoking: Smoking increases surgical risks and slows healing.
• Improve nutrition: Maintaining adequate nutrition helps the body recover after major surgery.
• Stay physically active: Gentle exercise, such as walking, may improve lung function and overall fitness.
• Follow fasting instructions: Patients are usually asked not to eat or drink for several hours before surgery.
• Review medications: Some medications, such as blood thinners, may need to be temporarily stopped.

Doctors and nurses will also explain the procedure, possible risks, and recovery expectations. Patients will have the opportunity to ask questions and give informed consent before surgery.

Oesophageal Cancer Surgery Procedure

Oesophageal cancer surgery is usually performed under general anaesthesia, meaning the patient is asleep and feels no pain during the operation. The procedure is complex and may take several hours to complete.

The most common procedure is an oesophagectomy, where part or all of the diseased oesophagus is removed along with nearby lymph nodes. Removing lymph nodes allows doctors to check whether cancer has spread and helps reduce the risk of recurrence.

Depending on the tumour’s location, the surgeon may operate through the abdomen, chest, or neck. In some cases, the procedure involves two or three surgical stages, each with a different incision.

After removing the cancerous portion of the oesophagus, the digestive tract must be reconstructed so food can continue to pass from the mouth to the stomach. The most common reconstruction method involves reshaping the stomach into a narrow tube and bringing it upward to connect with the remaining oesophagus. This technique is often referred to as a gastric pull-up.

Some surgeons operate using minimally invasive techniques, which involve small incisions and specialised laparoscopic or robotic instruments. These techniques may reduce pain, blood loss, and recovery time compared with traditional open surgery.

At the end of the procedure, temporary tubes may be placed to assist recovery. These may include a feeding tube, chest drains to remove fluid from around the lungs, and intravenous lines for medications and fluids.

What to Expect After an Oesophageal Cancer Surgery?

Recovery after oesophageal cancer surgery takes time, and patients are closely monitored in hospital during the initial recovery period.

Most patients spend a short time in an intensive care or high-dependency unit after surgery. This allows doctors and nurses to monitor breathing, heart function, and pain levels.

Patients are usually encouraged to begin gentle movement and breathing exercises soon after surgery. These exercises help reduce the risk of complications such as pneumonia or blood clots.

Eating normally is not possible immediately after surgery. Initially, nutrition may be provided through a feeding tube placed during the operation. As healing progresses, patients gradually begin drinking liquids, then soft foods, and eventually small,, regular meals.

Patients may notice some changes in how they eat and digest food after surgery. Because the stomach has been reshaped and moved higher into the chest, patients often need to eat smaller, more frequent meals.

Common recovery expectations include:

• Hospital stay: Usually between one and two weeks, depending on recovery.
• Dietary adjustments: Smaller, more frequent meals may be needed long term.
• Fatigue: Recovery from major surgery may take several weeks to months.
• Follow-up care: Regular appointments are needed to monitor healing and check for cancer recurrence.

Physiotherapy, dietitian support, and oncology follow-up are often part of the recovery process.

Oesophageal Cancer Surgery Prognosis

When the cancer is detected early and completely removed, surgery can offer a realistic chance of long-term survival or cure. Patients with early-stage disease generally have significantly better outcomes than those diagnosed at later stages.

Prognosis is influenced by factors such as:

• Cancer stage at diagnosis: Early cancers have higher survival rates.
• Lymph node involvement: Cancer spread to lymph nodes may reduce survival.
• Tumour type: Some cancer types respond better to treatment than others.
• Overall patient health: Patients in good physical condition often recover more successfully.
• Response to chemotherapy or radiotherapy: Tumours that respond well to treatment before surgery often have better outcomes.

Many patients receive additional treatments such as chemotherapy or immunotherapy after surgery to reduce the risk of recurrence.

Regular follow-up appointments, scans, and endoscopic examinations are used to monitor recovery and detect any signs of cancer returning.

Oesophageal Cancer Surgery Risks

Like all major operations, oesophageal cancer surgery carries potential risks and complications. Advances in surgical techniques and specialised centres have significantly improved safety, but complications can still occur.

Possible risks include:

• Infection: Surgical wounds or chest infections may occur during recovery.
• Bleeding: Although uncommon, bleeding may occur during or after surgery.
• Anastomotic leak: Leakage from the connection between the oesophagus and stomach can occur and may require additional treatment.
• Breathing complications: Pneumonia or lung problems can develop after chest surgery.
• Swallowing difficulties: Some patients experience temporary or long-term swallowing issues.
• Nutritional challenges: Changes in digestion may require dietary adjustments.

Doctors carefully monitor patients after surgery to detect and treat complications early.

What if Oesophageal Cancer Surgery is Delayed?

Delaying oesophageal cancer surgery may allow the tumour to grow or spread, which can reduce the chances of successful treatment.

Oesophageal cancers can become more advanced over time, potentially spreading to nearby lymph nodes or distant organs such as the liver or lungs. When cancer spreads, surgery may no longer be able to remove all of the disease.

Delays may lead to:

• Tumour progression: The cancer may grow deeper into the oesophageal wall.
• Spread to lymph nodes: Cancer cells may travel through the lymphatic system.
• Metastasis: Cancer may spread to other organs.
• Worsening swallowing problems: Tumours may block the oesophagus and make eating difficult.
• Reduced treatment options: Advanced cancers may require non-surgical treatments instead.

For these reasons, early diagnosis and timely treatment are important. If surgery cannot be performed immediately, doctors may recommend chemotherapy or radiotherapy to control the cancer until surgery becomes possible.
