Effect of Abdominal Compression on Total Single-Balloon Enteroscopy Rate: A Randomized Controlled Trial

To evaluate whether abdominal compression significantly increased the total enteroscopy rate in single-balloon enteroscopy (SBE). Consecutive patients who underwent SBE at 2 hospitals were prospectively included between June 1, 2020, and September 30, 2021. They were randomly divided into an abdominal compression group and a non–abdominal compression group with use of sealed envelopes generated by a computer. Total enteroscopy rates were compared between the groups. The study included 200 patients. The total enteroscopy rates were 73% and 16% in the abdominal compression and non–abdominal compression groups, respectively (relative risk, 13.55; 95% CI, 6.79 to 27.00; P
