Abstract

BACKGROUND

Diagnostic accuracy of double-contrast barium enema (DCBE) depends upon the barium sulfate coating efficiency in the colon.

OBJECTIVE

To evaluate effects of three laxatives on barium sulfate coating efficiency in the large intestine, sigmoid colon, and hepatic flexure in DCBE.

METHODS

This retrospective study included patients receiving DCBE after pre-procedure cleansing with Dulcolax with castor oil (DC), Klean-Prep (KP), or Fleet . Patients' DCBE images were reviewed.

RESULTS

Among 373 cases of DCBE, 151 received DC, 147 received KP, and 75 received Fleet. For DCBE, the optimal extent of barium sulfate residue coated on the wall of the large intestine is less than one-fourth of bowel wall width; the DC group had a higher percentage of less than one-fourth of bowel wall than that of the KP or Fleet group (both p < 0.0167). DC, KP and Fleet have comparable barium sulfate coating efficiency in the sigmoid colon. However, in the hepatic flexure, the DC group had a higher percentage of barium sulfate coating without interruption than that of the KP or Fleet groups (both p < 0.0167).

CONCLUSION

DC has a better barium sulfate coating efficiency in the hepatic flexure compared with KP and Fleet.

摘要

背景

双对比钡灌肠（DCBE）的诊断准确性取决于结肠内硫酸钡的涂层效率。

目的

评估三种泻药对 DCBE 中大肠、乙状结肠和肝曲钡剂涂层效率的影响。

方法

本回顾性研究纳入了接受 Dulcolax 加蓖麻油（DC）、Klean-Prep（KP）或 Fleet 进行肠道准备后行 DCBE 的患者。对患者的 DCBE 图像进行了回顾性分析。

结果

在 373 例 DCBE 中，151 例接受 DC，147 例接受 KP，75 例接受 Fleet。对于 DCBE，硫酸钡在肠壁上的最佳涂层残留量小于肠壁宽度的四分之一；DC 组小于四分之一肠壁的比例高于 KP 或 Fleet 组（均 p < 0.0167）。DC、KP 和 Fleet 在乙状结肠的硫酸钡涂层效率相当。然而，在肝曲，DC 组无中断硫酸钡涂层的比例高于 KP 或 Fleet 组（均 p < 0.0167）。
