Abstract:
BACKGROUND AND AIMS: The goal of this study was to examine whether certain variables are associated with insertion time during colonoscopy. METHODS: A total of 703 consecutive subjects underwent colonoscopy by a single endoscopist from April of 1998 to August of 1998. The insertion time during colonoscopy was checked and the factors that may affect insertion time were analyzed. RESULTS: The indications for colonoscopy were bowel habit change (34.8%), the diagnosis of and follow up for colonic neoplastic disease (31.6%), abdominal pain (22.8%), thin stool caliber (19.2%), hematochezia (16.1%), routine examination (10.7%), inflammatory bowel disease (9.4%), tenesmus (8.8%) and a family history of colonic disease (3.1%). Of 703 subjects, complete colonoscopy was possible in 678 (96.4%). Reasons for incomplete insertion included inadequate bowel cleaning (n=11), pain (n=6), a history of operations (n=3), and others (n=5). Therefore, the adjusted completion rate was 97.9% (678/692). The mean insertion time in complete colonoscopy was 7.07 4.26 min (range; 2~35 min). Multivariable analysis revealed that inadequacy of bowel preparation was significantly associated with prolonged (>10 min) insertion time (p=0.005), whereas the history of colorectal resection was inversely associated with prolonged insertion time (p=0.010). CONCLUSIONS: Among the factors affecting insertion time during colonoscopy, cleanness of the bowels is the only correctable factor.
