01Core principlesThe concepts and mechanisms needed to understand the subject.
Resection combines clearance with reconstruction. Ivor Lewis oesophagectomy has abdominal and thoracic phases and creates the oesophagogastric anastomosis in the chest; McKeown has thoracic, abdominal and cervical phases and creates it in the neck. Both commonly use a narrow gastric tube whose blood supply depends largely on the preserved right gastroepiploic pedicle. Gastrectomy extent follows tumour position and a clear proximal margin, with reconstruction restoring intestinal continuity.
Technical choices serve oncological and physiological goals. NICE says curative resections belong in a specialist surgical unit and must be performed by specialist oesophago-gastric surgeons; it supports two-field nodal dissection for oesophagectomy and consideration of D2 dissection for gastrectomy. D2 denotes defined regional stations beyond D1, not indiscriminate para-aortic clearance. Current gastric surgical guidance supports D2 for cT2–T4 or cT1 node-positive disease while preserving the spleen in suitable proximal cancers without greater-curvature involvement.
After surgery, tachycardia, atrial arrhythmia, oxygen need or confusion can herald an anastomotic or conduit leak. Contrast CT assesses mediastinal or pleural gas, fluid and effusions; experienced endoscopy can inspect mucosal viability but may enlarge a defect and is selected with the operating team. Source control combines drainage with endoscopic stent or vacuum treatment in selected contained leaks, or operation when contamination, tissue failure or instability demands it. Follow-up then continues for swallowing and nutrition without scheduling scans solely to detect recurrence in an otherwise well patient with no residual disease.
Key points
- Ivor Lewis oesophagectomy uses abdominal and right-thoracic phases with an intrathoracic anastomosis; McKeown adds a cervical phase and places the anastomosis in the neck. Tumour level, nodal field, prior therapy, physiology and specialist expertise determine the choice.
- The gastric conduit is usually perfused through the right gastroepiploic arcade; identifying and protecting that pedicle and checking the tube for viability are explicit reconstruction steps.
- Subtotal gastrectomy preserves function when a clear proximal margin is oncologically achievable; total gastrectomy is required for diffuse, proximal or extensive disease.
- D2 gastrectomy removes the operation-specific regional nodal stations beyond D1 for staging and local control. It is not routine para-aortic clearance; preserve uninvolved pancreas and, in appropriate proximal cancers without greater-curvature involvement, the spleen.
- Enhanced recovery combines prehabilitation, lung expansion, early mobilisation, analgesia, thrombosis prevention and planned enteral nutrition.
- Continue nutrition and symptom follow-up, but NICE advises against routine clinical or radiological surveillance solely to detect recurrence in an asymptomatic person with no residual disease; provide recurrence information and rapid MDT access if symptoms develop.
02Mechanisms and patternsImportant relationships and how to distinguish them.
Thoracic access, pain and recurrent laryngeal nerve dysfunction increase atelectasis, pneumonia and aspiration risk.
Tachycardia, fever, sepsis, neck discharge or enteric chest drainage can precede obvious radiological contrast leak.
Venous congestion or arterial insufficiency causes mucosal necrosis and failure of the reconstruction.
Vagal disruption and pyloric dysfunction can produce early satiety, regurgitation and aspiration after oesophagectomy.
Rapid small-bowel delivery, loss of reservoir and reduced intrinsic factor cause dumping, weight loss and micronutrient deficiency.
03Interpreting evidenceInformation, measurements and their limitations.
Consider the information, its meaning and its limitations before deciding what follows.
- 01
Preoperative cardiopulmonary assessment - Why
- Estimate whether radical resection and recovery are realistic.
- Interpretation and limitations
- Integrate performance status, frailty, pulmonary function and exercise capacity rather than using chronological age alone.
- 02
Nutritional assessment - Why
- Identify malnutrition, sarcopenia and refeeding risk before treatment.
- Interpretation and limitations
- Route and timing should support therapy without compromising conduit formation or causing avoidable aspiration.
- 03
Operative pathology - Why
- Determine margins, regression, depth and lymph-node yield.
- Interpretation and limitations
- Final stage directs prognosis and postoperative systemic treatment discussions.
- 04
CT for postoperative deterioration - Why
- Look for anastomotic leak, conduit compromise and undrained collections.
- Interpretation and limitations
- Absence of visible oral contrast extravasation does not exclude a contained leak; interpret gas, fluid and physiology together.
- 05
Endoscopic conduit assessment - Why
- Inspect mucosal perfusion and anastomosis when it can guide therapy.
- Interpretation and limitations
- Experienced teams can diagnose ischaemia and deliver vacuum or stent treatment, but unstable free contamination may still require surgery.
04Applied reasoningWorked examples connecting principles to decisions.
01Worked case: operation choiceMatch resection to location and prove clearanceA fit 57-year-old completes preoperative chemotherapy for a distal gastric adenocarcinoma; restaging and laparoscopy show no metastasis and the proximal stomach is endoscopically clear.+
- 1The specialist oesophago-gastric surgical unit reviews restaging, nutritional reserve and tumour position and selects subtotal rather than total gastrectomy because an adequate proximal margin is achievable.
- 2The specialist team performs subtotal gastrectomy with D2 lymph-node dissection and Roux-en-Y reconstruction, preserving the proximal reservoir without compromising the planned nodal field.
- 3Final pathology reports an R0 resection with a clear proximal margin and complete node count, so the postoperative oncology discussion uses the pathological response rather than the preoperative scan alone.
- 4Verify functional recovery as well as cancer clearance: before discharge the patient tolerates six small oral intakes, mobilises independently and has a documented dietetic, B12/haematinic and oncology follow-up plan.
02Worked case: postoperative leakDiagnose the defect and control contaminationOn day four after Ivor Lewis oesophagectomy, a patient develops new atrial fibrillation, fever and increasing oxygen requirement.+
- 1Stop oral intake, begin sepsis resuscitation and involve the operating upper-GI, critical-care, radiology and endoscopy teams immediately.
- 2Urgent contrast CT shows perianastomotic mediastinal gas and a loculated right pleural collection; a chest drain returns turbid fluid and improves oxygenation.
- 3Careful specialist endoscopy finds a contained anastomotic defect with viable gastric conduit, so a covered stent is placed and enteral nutrition is delivered by the established jejunal route while drainage continues.
- 4Verify source control: fever and vasopressor need resolve, drain output falls, interval imaging shows collection collapse and a later contrast study confirms sealing before oral intake resumes.
03Worked case: recovery ownershipExtend care beyond dischargeA patient loses weight and coughs at night six weeks after oesophagectomy.+
- 1Assess swallowing, aspiration, conduit emptying, anastomotic narrowing and recurrence rather than recommending generic supplements alone.
- 2Use dietetic review, endoscopy or contrast imaging according to the suspected mechanism.
- 3Treat a demonstrated stricture, reflux or delayed emptying and adjust meal structure.
- 4Recheck weight, intake and respiratory symptoms after the intervention.
05Checking understandingVerify the reasoning, revisit uncertainties and apply feedback.
- Use daily respiratory, mobility, pain and fluid goals during the early postoperative period.
- Escalate unexplained tachycardia, arrhythmia, fever or oxygen requirement for leak assessment.
- Track drain output and character together with inflammatory markers and imaging.
- Record final stage, margins, node yield and response to neoadjuvant treatment at MDT review.
- Continue weight, swallowing, dumping, bowel and micronutrient review. In an asymptomatic patient with no residual disease, do not add clinic visits or imaging solely to detect recurrence; give symptom information and rapid specialist MDT access.
06Special situationsVariants, exceptions and circumstances that change the usual approach.
Reconstruction determines later symptoms
A technically clear cancer resection can still leave aspiration, dumping or delayed emptying if the conduit performs poorly.
Tachycardia is a leak sign
It may appear before abdominal guarding or obvious wound discharge after major upper-GI surgery.
Subtotal is functional only when oncological
Preserving stomach benefits eating only if a safe cancer margin and lymphadenectomy remain possible.
Final pathology resets prognosis
Clinical and radiological stage must yield to the resection specimen for postoperative planning.
07Common pitfallsFrequent interpretation and management errors.
- 01
Using age alone to deny or mandate major resection.
- 02
Ignoring new arrhythmia as an isolated cardiac event after oesophagectomy.
- 03
Advancing oral intake during suspected conduit leak.
- 04
Discharging without lifelong nutritional and symptom follow-up.
