Factors Predict Difficult Colonoscopy Before the Procedure: Prospective Registry Study

In this study, the investigators aim to evaluate the relationship between cecal intubation time during colonoscopies and factors such as the patient's age, body mass index, history of constipation, Wexner constipation score, antidepressant use, and previous abdominal surgery. The objective is to assess factors that may predict longer cecal intubation times, especially in difficult colonoscopies. Prior to the procedure, informed consent will be obtained from patients scheduled for colonoscopy in the surgical endoscopy unit, and relevant information will be recorded. During the procedure, data will be collected, including cecal intubation time, if ileal intubation is performed, and the total procedure time.
