Sedated gastroscopy improves detection of gastric polyps.

The detection rate of gastric polyps (GPs) is low, improving the detection rate would be good. The present study aimed to evaluate the role of sedated gastroscopy in GP detection. The data of patients who underwent gastroscopic examination from January 2014 to December 2016 at the First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China) were retrospectively reviewed. Endoscopic records of 6,195 patients diagnosed with GPs were analyzed. The GP detection rate was 3.12 and 5.11% in the unsedated and sedated gastroscopy group, respectively (P<0.05). Also after stratification by sex, the GP detection rate was significantly higher in the sedated gastroscopy group (P<0.05). In addition, patients aged ≥20 years in the sedated gastroscopy group had a higher GP detection rate than those in the unsedated gastroscopy group (P<0.05). The incidence of cardiac, gastric fundus, gastric body and multiple-site GPs was significantly different between the two groups (P<0.05). GPs ≤0.5 and >0.5 cm were more common in the sedated gastroscopy group than in the unsedated gastroscopy group (P<0.05). The common pathologic types of GPs were gastric fundus gland (52.27%) and hyperplastic polyps (34.74%). In conclusion, the GP detection rate may be improved by inhibition of gastric muscle cramping with sedation.
