When is surgery considered?
Surgery may be considered when the cancer can be removed and the person is fit enough for the operation. Some very early cancers can be treated endoscopically. When disease has spread, medicines and symptom control may take priority. The discussion should clarify whether an operation aims to treat the cancer or relieve bleeding or obstruction.
Diagnosis and staging
Endoscopy with biopsy usually establishes the diagnosis. Imaging assesses local and distant spread; endoscopic ultrasound or staging laparoscopy may be useful in selected cases. Anaemia, weight loss and ability to eat are assessed alongside tumour findings. Previous images and pathology material can be as helpful as the written reports.
Treatment sequence and alternatives
A multidisciplinary team considers whether treatment should begin with surgery or cancer medicines. Endoscopic treatment applies only to carefully selected superficial tumours. If removal is not possible, a stent or bypass may help food pass. Each option should be discussed in terms of its purpose, burden and likely effect on eating.
What does the operation involve?
Part or all of the stomach may be removed, together with the relevant lymph nodes. The digestive tract is then reconnected. Removing neighbouring organs is not routine; the spleen does not automatically need removal. The choice of an open or minimally invasive approach depends on the disease and safe completion of surgery.
Risks and preparation
Possible complications include bleeding, infection, blood clots, chest problems and leakage from a new join. Nutrition, anaemia, smoking and other illnesses influence preparation. Medicines, including blood thinners, need an individual plan. Pain relief, breathing exercises and assisted mobilisation are discussed before the operation rather than left until discharge.
Rebuilding an eating routine
Eating is restarted according to the operation and recovery. Smaller, more frequent meals and adequate protein and fluid may help, with a dietitian adapting the plan. Rapid food transit can cause sweating, dizziness or diarrhoea after meals. Total gastrectomy requires a vitamin B12 replacement plan and monitoring for other nutritional deficiencies.
Pathology and longer-term follow-up
Final pathology refines the assessment of tumour depth, lymph nodes and surgical margins, helping guide further treatment. Follow-up also considers weight, blood counts, nutritional deficiencies, swallowing and daily function. Ongoing difficulty eating deserves attention even when cancer investigations are reassuring; support should address symptoms as well as surveillance.
When to seek urgent help
Seek urgent assessment for worsening abdominal or chest pain with fever, breathlessness, fainting, vomiting blood or black stools. Inability to drink, repeated vomiting or markedly reduced urine also needs prompt advice. Discharge instructions should identify whom to contact and where to attend when help is needed outside usual hours.
