Washout versus non-washout (Picolax) preparation for double-contrast barium enemas
Abstract:
A non-washout preparation using Picolax in 40 patients, compared with a standard method using washouts in 38 patients, showed no significant difference in the contamination by residual formed or semiliquid faeces, although Picolax was associated with significantly more contamination due to adherent faeces and mucus. The overall differences in contamination were most marked in the transverse colon. Picolax also affected the smooth muscle tone of the bowel wall, causing an increase in 'mucosal crinkling'.
Insights
Picolax bowel preparation showed no significant difference in residual stool contamination compared to standard washout methods. However, Picolax increased adherent feces, mucus, and mucosal changes, particularly in the transverse colon.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Medical Device Technology
Background:
- Effective bowel preparation is crucial for colonoscopy and colorectal surgery.
- Traditional bowel prep often involves washout procedures, which can be time-consuming and inconvenient.
- Picolax offers a non-washout alternative for bowel preparation.
Purpose of the Study:
- To compare the efficacy and safety of Picolax non-washout bowel preparation with standard washout methods.
- To assess the degree of fecal contamination after both preparation methods.
- To evaluate the impact of Picolax on bowel wall characteristics.
Main Methods:
- A comparative study involving 40 patients using Picolax (non-washout) and 38 patients using standard washout.
- Assessment of residual fecal contamination, including formed, semi-liquid, and adherent feces, as well as mucus.
- Evaluation of changes in bowel wall smooth muscle tone and mucosal appearance ('mucosal crinkling').
Main Results:
- No significant difference in contamination by residual formed or semi-liquid feces between Picolax and standard washout.
- Picolax was associated with significantly higher contamination from adherent feces and mucus.
- Picolax increased 'mucosal crinkling', indicating an effect on smooth muscle tone, most notably in the transverse colon.
Conclusions:
- While Picolax offers a non-washout option, it may lead to increased adherent fecal and mucus contamination.
- Picolax impacts bowel wall physiology, evidenced by increased mucosal changes.
- Further research is needed to optimize non-washout bowel preparation strategies.
