概要 | OBJECTIVES:In patients with ulcerative colitis (UC), colonoscopy is an essential procedure for evaluating mucosal damage, and treatment outcomes. A new flexible ultrathin colonoscope (PCF-PQ260) has been developed to pass through tortuous and narrow lesions of the colon readily and cause minimum patient discomfort. The objective of this study was to evaluate the comfort and performance of this new type scope in UC patients, who were to undergo colonoscopy for estimation of mucosal inflammation, basically without sedation.METHODS:In a prospective, single centerMETHODS:setting, among 107 UC patients who were to undergo colonoscopy, 84 eligible cases were randomly assigned to the new ultrathin flexible colonoscope, PCF-PQ260 (n=42) or to a conventional colonoscope, PCF-Q260A (n=42). The main outcome measure was patients' pain level determined by using a visual analogue scale (VAS) with 0=none, and 100=extremely painful. Other outcomes were cecal intubation time, the rate of complete intubation (to reach the cecum) and the rate of procedural complications.RESULTS:The VAS score was significantly lower in the new scope group as compared with the conventional scope group; new scope group vs conventional scope group, mean ± SD, median (range): 19.3±16.9, 14 (0-62) vs 32.0±21.6, 31.8 (0-100, P=0.005). However, cecal intubation rate (97.6%) and time (4min) were similar in the two groups. There was no procedure related serious complication in either group.CONCLUSIONS:The findings of this study indicated that the flexible ultrathin colonoscope, PCF-PQ260 has significantly better tolerability in UC patients as compared to a conventional colonoscope. |
