Difficult Colonoscopy and Personality Traits

The cecal intubation time (CIT) refers to the time required for the tip of the colonoscope to reach the cecum from passing through the anus. A prolonged CIT is considered a marker of difficulty in colonoscopy. CIT greater than 10 minutes is considered a difficult colonoscopy. Studies have identified factors that influence CIT, including age, gender, body mass index (BMI), waist circumference, bowel preparation, prior abdominal surgery, etc. Personality traits have been found to be associated with the onset of many diseases, such as hypertension and A-type personality, depression and neurotic personality. According to the Big Five personality theory, personality can be decomposed into five dimensions: openness (O), conscientiousness (C), extraversion (E), agreeableness (A), and neuroticism (N). There is a lack of research on the association between personality traits and colonoscopy insertion time, and the purpose of this study is to investigate whether personality, BMI, age, gender, anxiety and depression index, metabolic diseases, and abdominal pelvic surgery history lead to prolonged colonoscopy insertion time and difficult colonoscopy, and to identify significant variables as predictors by using machine learning methods to build a clinical diagnostic model to predict colonoscopy insertion time and identify difficult colonoscopy patients.
