ObjectiveTo explore the clinical application effect of water and gas injection painless enteroscope. MethodsA total of 180 subjects accorded with the indications of painless enteroscope with or without clinical intestinal symptoms were selected and divided into group A (conducted water and gas injection painless enteroscope), group B (conducted water injection painless enteroscope) or group C (conducted gas injection painless enteroscope), with 60 cases in each group. The access and withdrawal time of the endoscope, intestinal cleanliness score, detection rate of intestinal adenoma, and abdominal discomfort after examination were compared between the three groups. ResultsThe access time of endoscope exhibited a tendency of group A ＜group B ＜group C (P＜0.05); the withdrawal time of endoscope of the group A or group C was shorter than that of group B (P＜0.05), but with no significant difference between the group A and group C (P＞0.05); Boston score of intestinal cleanliness and detection rate of intestinal adenoma were higher, but abdominal discomfort after examination was less in group A or group B than in group C (all P＜0.05), with no significant difference between the group A and group B (P＞0.05). ConclusionWater and gas injection painless enteroscope can effectively solve various kinds of disadvantages caused by simple water or gas injection painless enteroscope, reduce the anesthesia risk and the adverse reactions after examination, and increase the detection rate of intestinal adenomas, thus it is of good application prospect.
