Randomized Controlled Trial Comparative StudyAdministration of olive oil followed by a low volume of polyethylene glycol-electrolyte lavage solution improves patient satisfaction with right-side colonic cleansing over administration of the conventional volume of polyethylene glycol-electrolyte lavage solution for colonoscopy preparation.
Proper bowel cleansing before colonoscopy is essential for satisfactory evaluation of the colon. The required consumption of a large volume of salty-tasting liquid, 4 L of polyethylene glycol-electrolyte lavage solution (PEG-ELS), is the primary limitation to achieving this goal. ⋯ Pretreatment with olive oil before administration of a low volume of PEG-ELS enhances both patient satisfaction and the quality of right-side colonic cleansing over the administration of the conventional volume of PEG-ELS for colonoscopy preparation. Although the magnesium hydroxide regimen (Prep 2) was the preferred regimen in this study, its colonic cleansing effectiveness was not as great as those of the other regimens. Based on our results, the olive oil regimen is recommended, especially for patients who are not able to consume large volumes of liquids, such as the elderly, and those who are suspected of having subtle right-side colonic lesions.

Comparative StudyHigher hospital volume is associated with lower mortality in acute nonvariceal upper-GI hemorrhage.
Acute nonvariceal upper-GI hemorrhage (NVUGIH) is associated with significant morbidity and mortality. ⋯ Higher hospital volume is associated with lower mortality and with higher rates of endoscopy and endoscopic intervention in patients with NVUGIH.
