Factors that predict incomplete colonoscopy: thinner is not always better

Abstract OBJECTIVE: The aim of this study was to determine whether anatomic factors such as body mass index (BMI) impacts the success rate of cecal intubation during colonoscopy. METHODS: We retrospectively reviewed the cecal intubation rate of 2000 colonoscopies performed at our institution from March 1997 to March 1999. The analysis sample was composed of charts for all incomplete procedures and a sample (23%) of complete examinations that were randomly selected. Data collected included age, gender, height, weight, bowel habits, abdominal surgery, psychiatric medication use, the presence of diverticular disease, amount of sedation administered, and location and reason for halting the examination. Patients were divided by BMI: thin (BMI ≤22.1), average weight (BMI >22.1–25.0), overweight (BMI = 25.1–29.9), and obese (BMI >30). RESULTS: Colonoscopies in women had a lower adjusted completion rate (94.8%) than in men (98.2%) (p CONCLUSIONS: Women with a low BMI (especially

Anatomic location of significant colorectal neoplasia in male patients who smoke

Purpose: There is little data regarding anatomic distribution of significant adenomatous polyps (>1 cm) in smokers. Our aim was to determine if there is an association between smoking and the anatomic location of significant polyps.
