RESUMO
In this study, we investigated the relationship between the cecal intubation time (CIT) and the form and method used for passing through the sigmoid/descending colon junction (SDJ) and the hepatic flexure using an endoscopic position detection unit (UPD), with reference to various factors [age, sex, body mass index (BMI), history of abdominal and pelvic surgery, and diverticulum]. A total of 152 patients underwent colonoscopy with UPD. The mean age was 66.9â ±â 12.4 years, and the male to female ratio was 3.6:1. The average CIT time was 14.3â ±â 8.2â min. Age, number of experienced endoscopies, history of abdominal and pelvic surgery, BMI, and diverticulum were associated with prolonged CIT; SDJ passage pattern was straight: 8.6â ±â 5.0, alpha loop: 11.8â ±â 5.6, puzzle ring-like loop: 20.2â ±â 5.0, reverse alpha loop: 22.4â ±â 9.7, and other loop: 24.7â ±â 10.5. The hepatic flexure passing method was in the following order: right rotation maneuver: 12.6â ±â 6.6, push maneuver: 15.1â ±â 5.9, and right rotation with positional change maneuver: 20.5â ±â 7.2. In conclusion, colonoscopy with UPD revealed an association between CIT and SDJ passage pattern and hepatic flexure passing method.
