In this article, we will discuss the general points about Gastrectomy. So, let’s get started.


  • It is defined as the removal of the whole or part of the stomach.
  • It is mostly indicated for stomach/duodenal ulcers; however, recently it is used primarily for gastric adenocarcinomas, primary gastric lymphomas or leiomyosarcomas.
  • Gastrectomy is either partial, total or sleeve.
  • Antrectomy, a limited form of gastrectomy in which the antrum(part of the stomach) is removed.
  • Gastrectomy can either be performed via open surgery or laparoscopic surgery.
  • Risks include acid reflux, diarrhea, gastric dumping syndrome, infection, internal bleeding (hemorrhage), leakage from the site of incision (operation), nausea, vomiting, stomach acid leaking into the esophagus causing scarring, narrowing or constriction (stricture), vitamin deficiency, weight loss, dyspnea, pneumonia or damage to the adjacent structures.
  • Vitamin and mineral supplementation is necessary post gastrectomy.
