Stomach (Gastric) Cancer — Gastric Cancer Operations

Subtotal or total gastrectomy with oncologic lymphadenectomy — open, laparoscopic, or robotic access.

Gastrectomy removes the tumor with safe margins and clears the relevant nodal stations (commonly D2 principles in Eastern/Western guideline-informed practice). Distal tumors may allow subtotal gastrectomy; proximal or diffuse disease more often needs total gastrectomy with esophagojejunostomy. Reconstruction (often Roux-en-Y) restores continuity. Approach choice never excuses incomplete oncology. Staging laparoscopy and cytology, when indicated, can change the plan before major resection.

Figure labels (English)

  • Resection options
  • Reconstruction

Who may be a candidate?

  • Resectable gastric adenocarcinoma after appropriate staging
  • Completion surgery after neoadjuvant therapy when planned
  • Selected emergency resections for bleeding/obstruction (intent may be palliative)

Possible advantages

  • Cornerstone of cure for localized disease
  • Subtotal preservation of some reservoir when oncologically safe
  • Minimally invasive options in experienced centers for selected cases

Limits & realistic expectations

  • Total gastrectomy changes lifelong nutrition/vitamin needs
  • Anastomotic leak and duodenal stump risks require vigilant aftercare
  • Extensive carcinomatosis is not solved by bigger resections

Step-by-step overview

  1. 1

    Clarify the clinical question

    What diagnosis is being confirmed and what decision follows?

  2. 2

    Choose first-line tests

    Start with the test that answers the leading question safely.

  3. 3

    Stage if needed

    Add imaging or endoscopy when results would change management.

  4. 4

    Name limitations

    No test replaces exam; false reassurance is a risk.

  5. 5

    Link to next step

    Diagnosis should point to observation, medical care, or procedure.

Key points

  • Technique vs indication

    Key note inside

    A named technique is only useful when anatomy and disease biology fit. Conversion to another approach can be a safety decision, not a failure. Discuss timing, alternatives, and follow-up with your surgical team before you finalize a plan.

Frequently asked questions

  • Who is a candidate for gastrectomy?

    Candidacy depends on confirmed diagnosis, anatomy, fitness for anesthesia, and whether the expected benefit outweighs procedural risk.

  • What are common recovery themes?

    Early walking, pain control, diet advancement, and temporary activity limits are typical; exact timelines are individualized.

  • What warning signs after surgery need urgent review?

    Fever, worsening pain, wound problems, vomiting with inability to pass stool or gas, shortness of breath, or heavy bleeding.
