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
Clarify the clinical question
What diagnosis is being confirmed and what decision follows?
- 2
Choose first-line tests
Start with the test that answers the leading question safely.
- 3
Stage if needed
Add imaging or endoscopy when results would change management.
- 4
Name limitations
No test replaces exam; false reassurance is a risk.
- 5
Link to next step
Diagnosis should point to observation, medical care, or procedure.

Technique vs indication
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.
