Abstract
Viscous mucus of Helicobacter pylori-positive chronic gastritis disturbs endoscopic observation. We evaluated the efficacy of cleaning in the stomach using an oral intestinal lavage solution used in colonoscopy in order to develop a new cleaning method that can be observed without trouble. This research is intended for 40 cases made endoscopic observation more difficult by mucus , bile and residue in the stomach. In addition to the preparation of the oral cleaning solution [proteolytic enzyme (pronase MS) 2 hundred thousand units, sodium bicarbonate 1 g, dimethylpolysiloxane (Gascon) 4 ml with water of 50 ml], we compared and evaluated the efficacy of cleaning on the gastric body greater curvature between the group using the conventional lavage solution (dimethylpolysiloxane with water) 200 ml and the group using the oral intestinal lavage solution (PEG) 200 ml. We scored criteria of mucous in the stomach in 5 steps.
The result determined that the efficacy of before and after cleaning after 5 minutes was recognized significantly in the group using PEG higher than in the group using the conventional lavage solution.
If the thickened mucus, bile and residue disturbs endoscopic observation, we considered oral intestinal lavage solution (PEG) method can be expected as a new cleaning method in the stomach.
