RESUMO
BACKGROUND AND AIMS: Various methods have been reported as aids to cecal intubation. This study aimed to prospectively investigate whether an abdominal obstetric binder (AOB) used during pregnancy and attached to the patients' abdomen during colonoscopy could facilitate effective colonoscopic insertion. METHODS: This was a prospective study of 451 consecutive outpatient colonoscopies performed by a single experienced endoscopist. The recruited patients were randomly separated into two groups that received colonoscopy either with (Group A) or without an AOB attached (Group B). The cecal intubation time, cecal intubation length of the colonoscope, use of manual pressure, position change of each patient, and the number of patients with abdominal distension were collected for comparison. RESULTS: A total of 451 patients (224 in Group A and 227 in Group B) were ultimately included in this study. In Group A, cecal intubation time and cecal intubation length of colonoscope (CIL) were significantly reduced (P < 0.001). The patients had significantly fewer position changes and manual pressure in Group A (P < 0.001). Significantly less abdominal distension was reported by patients in Group A (P < 0.001). CONCLUSIONS: During colonoscopy, the application of an AOB provided a significantly faster and more effective colonoscope insertion.
