Efficacy of a gastroscope for cecal intubation during colonoscopy in patients with severe sigmoid adhesion

Background: Cecal intubation during colonoscopy is difficult to achieve in patients with severe sigmoid adhesions. This retrospective observational study assessed the efficacy of using a gastroscope for colonoscopy in patients with severe sigmoid adhesions. Furthermore, the ability of computed tomography (CT) to predict the possibility of cecal intubation using a gastroscope was examined. Methods: A total of 1,626 patients who underwent colonoscopy for total colon observation by one endoscopist were enrolled. Cecal intubation rate and other procedure-related outcomes were evaluated. We also investigated whether identification of the sigmoid colon pathway by CT was involved in cecal intubation rate using a gastroscope. Results: Of the enrolled patients, cecal intubation by colonoscope was not feasible in 19 patients (1.2%) because of severe sigmoid adhesions. Cecal intubation was possible in 13 patients (68.4%) using a gastroscope, and the cecal intubation rate of peritoneal carcinomatosis (0%, p
