Effect of squatting toilet behavior on gastric transit time and complete examination rate of small bowel during capsule endoscopy

Abstract

Objective To study the effect of squatting toilet behavior on gastric transport time (GTT) and complete examination rate of small bowel (CER) during capsule endoscopy. Methods A total of 122 patients who underwent capsule endoscopy at the Second Affiliated Hospital of Chongqing Medical University from January to December 2019 were recruited and randomly divided into test group (n=63) and control group (n=59). The patients of the test group were asked to take squatting posture for toileting after swallowing the capsule, while those of the control group were asked to take sitting in defecation if needed. GTT, small bowel transit time (SBTT), CER and diagnostic yield (DY) were compared between the 2 groups. Results There were no significant differences in gender, age and conditions during hospitalization between the test group and the control group. The test group obtained obviously higher CER (92.06% vs 79.66%, P=0.048) and shorter GTT (26.7 vs 45.6 min, P=0.027) when compared with the control group. No statistical differences were seen in SBTT and DY between the 2 groups. Conclusion Squatting posture for toileting of patients accepted capsule endoscopy can reduce the transit time of capsules in the stomach and increase the CER.
