Stomach polyps are growths that develop on the lining of the stomach and are often discovered during a gastroscopy performed to investigate digestive symptoms or as part of a medical evaluation. Although many stomach polyps are benign and do not cause problems, some may need to be removed to reduce the risk of complications or to allow further examination under a microscope. Gastroscopy is both a diagnostic and therapeutic procedure, enabling doctors to identify abnormalities within the upper digestive tract and remove selected polyps during the same session when appropriate. 

If you are looking for a gastroscopy clinic Singapore, the team at Andrea’s Digestive Clinic offers gastroscopy and the assessment of stomach conditions. In this article, we explain how stomach polyps are diagnosed during gastroscopy, when polypectomy may be recommended and what you can expect before, during and after the procedure.

What Are Stomach Polyps and Why Do They Develop?

Stomach polyps are abnormal growths that form on the inner lining of the stomach. Most are small, cause no symptoms and are discovered incidentally during a gastroscopy performed for unrelated digestive concerns. While the majority are non-cancerous, certain types have the potential to develop abnormal or cancerous changes over time, making accurate diagnosis important.

Several factors may contribute to the development of stomach polyps. Chronic inflammation of the stomach lining, such as that caused by Helicobacter pylori infection, can increase the risk of some types of polyps. Long-term use of proton pump inhibitors (PPIs), which are commonly prescribed to reduce stomach acid, has also been associated with the formation of fundic gland polyps. Less commonly, inherited conditions such as familial adenomatous polyposis (FAP) may lead to multiple stomach polyps and increase the risk of gastrointestinal cancers.

Because stomach polyps rarely cause noticeable symptoms, many people are unaware they have them. Larger polyps or those that bleed may occasionally cause abdominal discomfort, nausea, anaemia or signs of gastrointestinal bleeding. Identifying the type and characteristics of a stomach polyp is an important step in determining whether it can be monitored or whether removal through a polypectomy is recommended.

How a Gastroscopy Helps Diagnose Stomach Polyps

Gastroscopy is the primary procedure used to diagnose stomach polyps. During the examination, a thin, flexible tube with a camera is gently passed through the mouth into the oesophagus, stomach and first part of the small intestine, allowing the doctor to examine the lining in detail. If a polyp is found, its size, shape, location and surface appearance are carefully assessed to help determine its likely type and whether it appears suspicious. 

Photographs may be taken to document the findings, and one or more tissue samples (biopsies) can be collected for laboratory analysis. The biopsy results help confirm the nature of the polyp and guide decisions on whether monitoring, further investigation or removal through polypectomy is the most appropriate next step.

When Is Polypectomy Recommended?

Not every stomach polyp needs to be removed, and the decision to perform a polypectomy depends on several factors. The doctor will consider the polyp’s size, appearance and location, as well as whether it is causing symptoms such as bleeding or contributing to anaemia. Biopsy results are also important, as some types of polyps carry a higher risk of developing precancerous or cancerous changes than others. 

Larger polyps or those with suspicious features are generally more likely to be recommended for removal. In many cases, removing the polyp not only treats the abnormal growth but also allows the entire tissue to be examined under a microscope, providing a more definitive diagnosis and helping determine whether any further treatment or follow-up is required.

How Stomach Polyps Are Removed During Gastroscopy

Many stomach polyps can be removed during the same gastroscopy in which they are detected, avoiding the need for a separate procedure. The removal technique depends on the size, shape and characteristics of the polyp. Smaller polyps are often removed using a cold snare, while larger polyps may require a hot snare that uses electrical current to remove the tissue and reduce bleeding. 

For selected larger or flatter lesions, endoscopic mucosal resection (EMR) may be performed to remove the polyp more completely. Throughout the procedure, the doctor carefully monitors for bleeding and can use specialised endoscopic techniques to control it if necessary. The removed tissue is then sent to a laboratory for detailed examination to confirm the diagnosis.

Recovery After Gastroscopy With Polypectomy

After a gastroscopy with polypectomy, most patients are monitored for a short period while the effects of sedation wear off before going home on the same day. It is common to experience mild bloating, a sore throat or slight discomfort, but these symptoms usually resolve quickly. Your doctor will advise when you can resume eating and drinking, as well as any temporary dietary or activity restrictions based on the procedure performed. 

The results of the laboratory analysis are typically discussed during a follow-up appointment to determine whether additional treatment or surveillance is needed. Although complications are uncommon, seek prompt medical attention if you develop severe abdominal pain, persistent vomiting, fever, difficulty swallowing or significant bleeding after the procedure.

Conclusion

Stomach polyps are often found incidentally during a gastroscopy and many are harmless. However, some require closer evaluation or removal depending on their size, type and appearance. Gastroscopy allows doctors to diagnose stomach polyps accurately and, when appropriate, perform a polypectomy during the same procedure, reducing the need for additional treatment.
