BACKGROUND/AIMS: Optimal small bowel (SB) preparation for video capsule endoscopy (VCE) is controversial. Our study aimed to support the use of a specified volume of 4 liters of clear liquids for bowel preparation for VCE.
A retrospective review of 284 patients who underwent SB preparation with 2 liters of polyethylene glycol (PEG) and 284 patients who had 4 liters of clear liquid preparation. We analyzed image quality, endoscopic findings, completion rate, and transit times.
The 4-liter clear liquid group had significantly higher mean image quality scores when compared to the PEG group (2.908±0.77 to 2.669±0.64, p<0.0001), as well as more studies with adequate preparation (72% to 64%, p=0.0214). Although the PEG group had more endoscopic findings on VCE (40% to 23%, p<0.0001), there was a significant difference in the indications for the procedure between the groups. There was no difference in the capsule completion rate or SB transit time.
Our data demonstrate significantly higher mean image quality scores when using a specified volume of 4 liters of clear liquid compared to 2 liters of PEG. This study supports the growing evidence of the effectiveness of a 4-liter clear liquid SB preparation as opposed to PEG for VCE.
背景/目的：视频胶囊内镜检查（VCE）的最佳小肠（SB）准备方法存在争议。我们的研究旨在支持使用特定体积为4升的清亮液体进行VCE的肠道准备。
回顾性分析284例接受2升聚乙二醇（PEG）进行SB准备的患者和284例接受4升清亮液体制备的患者。我们分析了图像质量、内镜检查结果、完成率和传输时间。
与PEG组相比，4升清亮液体组的平均图像质量得分显著更高（2.908±0.77对2.669±0.64，p<0.0001），且准备充分的研究更多（72%对64%，p=0.0214）。虽然PEG组在VCE上有更多的内镜检查发现（40%对23%，p<0.0001），但两组之间的检查适应证存在显著差异。胶囊完成率或SB传输时间没有差异。
我们的数据表明，与2升PEG相比，使用特定体积为4升的清亮液体时平均图像质量得分显著更高。这项研究支持越来越多的证据表明，与PEG相比，4升清亮液体SB准备用于VCE是有效的。
