Sedated gastroscopy improves detection of gastric polyps

Area of Science:

• Gastroenterology
• Endoscopy
• Oncology

Background:

• Improving the detection rate of gastric polyps (GPs) is crucial for early diagnosis and management.
• Gastroscopy is a primary tool for GP detection, but current rates are suboptimal.

Purpose of the Study:

• To evaluate the impact of sedation on the detection rate of gastric polyps during gastroscopy.
• To compare GP detection rates between sedated and unsedated gastroscopy procedures.

Main Methods:

• Retrospective analysis of endoscopic records from 6,195 patients diagnosed with GPs.
• Comparison of GP detection rates between patients undergoing unsedated versus sedated gastroscopy.

Main Results:

• The GP detection rate was significantly higher in the sedated group (5.11%) compared to the unsedated group (3.12%).
• Sedation improved detection rates across different sexes, age groups (≥20 years), and for various polyp locations and sizes.
• Gastric fundus gland and hyperplastic polyps were the most common pathologic types.

Conclusions:

• Sedation during gastroscopy can significantly enhance the detection rate of gastric polyps.
• Inhibition of gastric muscle cramping through sedation appears to contribute to improved diagnostic yield.
