The polyp detection rate (PDR) is defined as the percentage of colonoscopies in which one or more polyps are detected, and has been shown to be highly correlated with the adenoma detection rate. The aim of the present study was to evaluate the PDR at the Endoscopy Unit of the Kasr Al-Ainy Hospital, Cairo University, Egypt, through the i-SCAN, Endocuff, and underwater colonoscopy techniques.
The study was conducted on 100 Egyptian subjects over 50 years of age. Their polyp detection rate was measured through 4 different colonoscopic techniques. An equal number of patients were divided into 4 groups: i-SCAN, Endocuff, underwater colonoscopy, and controls. The control group was examined using standard white light colonoscopy. The colonoscopy evaluation included the type of agent utilized for bowel preparation, preparation grade, and colonoscopy withdrawal time.
The general PDR was 48%. The i-SCAN technique had the highest rate (56%), followed by the underwater (52%) and the Endocuff (48%) techniques.
The i-SCAN and underwater colonoscopy techniques produced higher PDR than the Endocuff-assisted and standard techniques, but with no statistical significance.
息肉检出率（PDR）定义为在结肠镜检查中发现一个或多个息肉的百分比，并且已经证明与腺瘤检出率高度相关。本研究的目的是通过 i-SCAN、Endocuff 和水下结肠镜技术评估埃及开罗大学 Kasr Al-Ainy 医院内镜科的 PDR。
该研究纳入了 100 名 50 岁以上的埃及患者。通过 4 种不同的结肠镜技术测量他们的息肉检出率。将等量的患者分为 4 组：i-SCAN、Endocuff、水下结肠镜和对照组。对照组采用标准白光结肠镜检查。结肠镜检查评估包括用于肠道准备的药物类型、准备等级和结肠镜退镜时间。
总体 PDR 为 48%。i-SCAN 技术的检出率最高（56%），其次是水下（52%）和 Endocuff（48%）技术。
i-SCAN 和水下结肠镜技术比 Endocuff 辅助和标准技术产生更高的 PDR，但无统计学意义。
