Gastric Polypectomy During Gastroscopy: What Patients Need to Know and How to Prepare Properly
Stomach and duodenal polyps are a common finding during gastroscopy. In most cases, they are benign, but they still require removal to prevent possible complications or malignant transformation. That is why polypectomy is performed — a modern endoscopic procedure that allows polyps to be removed without surgical incisions or hospitalization.
In this article, we will explain:
- what polypectomy is;
- when it is performed;
- how to prepare properly for gastroscopy with possible polyp removal;
- what to expect after the procedure.
What Is Polypectomy?
Polypectomy is an endoscopic procedure used to remove polyps from the lining of the stomach or duodenum. It is performed during gastroscopy using special instruments such as snares or biopsy forceps.
Advantages of polypectomy:
- painless or minimally uncomfortable;
- does not require surgery;
- takes only 10–30 minutes;
- allows immediate histological examination of the removed polyp.
When Is Polypectomy Recommended?
Polypectomy is usually advised in the following situations:
- polyps are detected during gastroscopy;
- the polyp increases in size over time;
- there is suspicion of precancerous changes;
- symptoms are present (pain, nausea, anemia, bleeding).
In many cases, the doctor can remove the polyp immediately during diagnostic gastroscopy — provided the patient is properly prepared.
Preparation for Gastroscopy with Polypectomy: Step by Step
Polypectomy is usually advised in the following situations:
- 3–5 Days Before the Procedure
- Avoid alcohol.
- Do not eat fatty, fried, or spicy foods.
- After consulting your doctor, stop taking blood-thinning medications (aspirin, warfarin, etc.).
⚠️ Important: Never discontinue medication on your own — only under medical supervision.
- 24 Hours Before Gastroscopy
- Have a light lunch before 2:00–4:00 PM.
- In the evening, consume only clear liquids (water, weak tea).
- Avoid dairy products, coffee, and juices with pulp.
- On the Day of the Procedure
- Do not eat or drink for at least 6–8 hours before gastroscopy.
- Do not smoke.
- Do not chew gum.
- Arrive fasting.
If sedation (“medical sleep”) is planned, it is recommended to:
- come with a companion;
- avoid driving after the procedure.
How Is Polypectomy Performed?
- The patient receives local anesthesia or sedation.
- The doctor inserts the gastroscope through the mouth.
- The polyp is removed using a special endoscopic instrument.
- If needed, coagulation is performed to prevent bleeding.
- The removed tissue is sent for histological analysis.
Most patients feel no pain — only mild discomfort.
After Polypectomy: Recommendations
After the procedure, you may experience:
- mild sore throat;
- bloating;
- weakness (especially after sedation).
Recommendations:
- do not eat for 2–4 hours after the procedure;
- avoid hot or rough foods for 1–2 days;
- avoid hot or rough foods for 1–2 days;
- follow your doctor’s instructions carefully.
Histology results are usually available within 7–14 days.
Is Polypectomy Safe?
Yes. Polypectomy is considered a safe and routine procedure in modern endoscopy. Complications are rare and are usually related to underlying medical conditions or failure to follow post-procedure recommendations.
Conclusion
Polypectomy during gastroscopy is a modern, effective, and safe method for removing polyps without surgery. Proper preparation improves diagnostic accuracy and allows treatment to be completed in a single visit.
If gastroscopy has been recommended, do not delay the examination. Early detection and removal of polyps helps protect your health and prevent serious complications.
