Surgery for stomach cancer and GISTs - the right resection, in the right order.

Subtotal or total gastrectomy for gastric cancer, wedge or segmental resection for GIST, and neoadjuvant chemotherapy or imatinib timed by an upper GI cancer MDT. A named consultant upper GI surgeon, HDU on hand, and dietetics from day one.

The problem

The right operation and the right order - decided by an upper GI cancer MDT.

Stomach cancer surgery lives or dies on volume and MDT discipline. This is where volume matters, and where neoadjuvant timing matters as much as the surgery itself.

  • MDT decides staging and order

    FLOT before surgery for many gastric adenocarcinomas is now the standard - but only if MDT agrees the tumour is resectable and the patient is fit.

  • GISTs are not gastric cancer

    GISTs need clear margins and no lymphadenectomy. Confusing the two operations is a real risk in low-volume centres.

  • Nutrition, from the first appointment

    Weight loss, sarcopenia and low albumin drive complications. Prehab and dietetic input start on referral, not after surgery.

When it helps

When surgery is the right step for stomach cancer or a GIST.

The situations we see most, plus the red flag that means an emergency, not a routine referral.

  • Localised gastric adenocarcinoma

    T1b–T3, N0–N+ gastric cancer without distant metastases - resectable after neoadjuvant chemotherapy in most cases.

  • Gastric GIST above 2 cm or high-risk

    Symptomatic or growing GIST, or above 2 cm on staging endoscopy - wedge resection with clear margins.

  • Gastro-oesophageal junction tumour

    Siewert II–III GEJ tumours - extended gastrectomy or oesophago-gastrectomy after MDT review.

  • Early gastric cancer (T1a)

    Very early cancers can be treated by endoscopic submucosal dissection (ESD) - decided by MDT.

  • Recurrent GIST after imatinib

    Isolated recurrence in a good responder - resection after MDT review, alongside targeted therapy.

  • Neuroendocrine tumour of the stomach

    Type 1–2 usually endoscopically managed; type 3 needs formal gastric resection.

  • Hereditary diffuse gastric cancer (CDH1)

    Prophylactic total gastrectomy in confirmed CDH1 mutation carriers - a specialist pathway.

  • Red flag: obstruction, perforation or upper GI bleed

    Gastric outlet obstruction, perforation or significant upper GI bleeding is an emergency - A&E, not a routine referral.

Procedure options

Extent depends on the tumour and its biology.

Adenocarcinoma, GIST and neuroendocrine tumour each have their own operations - matched to biology and stage.

  • Subtotal gastrectomy with D2 lymphadenectomy

    The workhorse for antral and distal gastric cancers. Preserves gastric fundus and cardia - better long-term nutrition.

  • Total gastrectomy with Roux-en-Y

    For proximal, diffuse-type or Siewert III tumours. Full stomach removed, jejunum reconstructed to oesophagus.

  • Extended gastrectomy for GEJ tumour

    Trans-hiatal or thoraco-abdominal approach for Siewert II tumours - extends resection into the distal oesophagus.

  • Laparoscopic gastrectomy

    Small ports, faster recovery. Suitable for most subtotals and selected totals in high-volume hands.

  • Robotic-assisted gastrectomy

    Better dexterity for lymphadenectomy around the coeliac axis; outcomes comparable to laparoscopic in high-volume centres.

  • Wedge resection for gastric GIST

    Clear-margin resection, no lymphadenectomy. Small ports where possible.

  • Endoscopic submucosal dissection (ESD)

    For T1a early gastric cancers and small GISTs - done endoscopically, in high-volume upper GI cancer centres.

  • Palliative bypass or stenting

    Where the tumour is not resectable - endoscopic stenting or gastrojejunostomy to maintain nutrition.

Safety and recovery

What to expect afterwards - honestly.

Stomach cancer surgery is a major operation. The things worth planning are the MDT timing, the prehab, the nutrition plan, and the adjuvant therapy that follows.

  • General anaesthetic and enhanced recovery

    GA, epidural or TAP block, DVT prophylaxis, early chest care. HDU 24–48 hours for total gastrectomy.

  • Anastomotic leak - the feared complication

    Leak rates 3–8 percent depending on operation. Early detection with CRP, chest x-ray and drain fluid amylase where relevant.

  • Bleeding, pancreatic injury and chyle leak

    Major upper abdominal surgery - real risks that a high-volume team manages routinely.

  • Cardiac and respiratory complications

    Chest infection, atrial fibrillation and DVT/PE are the main post-op medical risks. Chest physio starts day one.

  • Nutrition and weight loss

    Every patient loses 10–15 percent of body weight after total gastrectomy. Long-term dietetic support and vitamin replacement are non-negotiable.

  • Dumping syndrome and reflux

    Early and late dumping, and biliary reflux, are common after gastrectomy. Diet strategy and, occasionally, medication.

  • Vitamin B12 and iron

    Lifelong B12 injections and iron supplementation after total gastrectomy. Regular blood monitoring for the first year.

  • Adjuvant FLOT or imatinib

    Adjuvant FLOT for gastric adenocarcinoma; adjuvant imatinib for three years for high-risk GIST. Started 6–8 weeks after surgery.

  • Red flags after surgery

    Fever, chest pain, breathlessness, ongoing vomiting, spreading redness or worsening abdominal pain - same-day team, or A&E.

Frequently asked

Everything we get asked about stomach cancer and GIST surgery.

Quick answers on chemotherapy timing, extent, GISTs, nutrition and cost.

  • Do I need chemotherapy before surgery, or straight to theatre?

    Most resectable gastric adenocarcinomas now receive four cycles of neoadjuvant FLOT chemotherapy before surgery and four cycles after - the FLOT4-AIO trial changed practice worldwide. Very early cancers (T1a) sometimes go straight to endoscopic dissection. Small, low-risk GISTs may go straight to wedge resection; larger or high-risk GISTs may benefit from neoadjuvant imatinib.

  • Total or subtotal gastrectomy - how do we decide?

    It depends on tumour location and type. Antral and distal cancers often permit a subtotal gastrectomy, which preserves some stomach and better long-term nutrition. Proximal, diffuse-type or hereditary (CDH1) tumours need a total gastrectomy. The decision is made at MDT after staging.

  • How is a GIST different from stomach cancer?

    GISTs (gastrointestinal stromal tumours) arise from a different cell line (interstitial cells of Cajal) and behave differently. They respond to targeted therapy (imatinib), rarely need lymphadenectomy, and can be cured by a clear-margin wedge resection. Confusing the two operations is a real risk in low-volume centres.

  • How much does private stomach cancer surgery cost in the UK?

    Subtotal gastrectomy £28,000–£42,000, total gastrectomy £34,000–£50,000, robotic £38,000–£55,000, extended gastrectomy for GEJ £40,000–£60,000, and GIST wedge £12,000–£18,000. Neoadjuvant and adjuvant chemotherapy are quoted separately.

  • How long is recovery?

    Subtotal gastrectomy: home at 5–8 nights, back to office work at 6–8 weeks. Total gastrectomy: home at 7–10 nights, back to work at 8–12 weeks, nutritional adjustment over 6–12 months. GIST wedge: home at 2–4 nights, back to work at 3–4 weeks.

  • Will I need to change how I eat?

    After total gastrectomy, yes - permanently. Small, frequent meals, protein-first, careful timing of fluids and sweet foods, lifelong B12 injections and iron. A specialist dietitian supports you for 12 months. After subtotal gastrectomy or GIST wedge, most people return to a normal diet within 6–12 weeks.
