Comparación de 2 tipos de preparación intestinal para la realización de colonoscopia en un hospital de tercer nivel

Abstract

Background

Colonoscopy is the method to evaluate the colon. The preparation with polyethylene glycol (PEG) is used for colonic cleansing. However, tolerability and side effects are common.

Objetive

To compare effectiveness through Boston Bowel Preparation Scale (BBPS) and Harefield Cleasing Scale (HCS), and tolerability with the visual analog scale in 2 types of colonic preparation: group 1 = PEG 4 liters (4L PEG) and group 2 = 30 ml olive (OL) plus PEG in 2 liters of water (30 OL + 2L PEG).

Methodology

Clinical, prospective, randomized, single-center trial. The subjects were randomized into 2 groups: 4L PEG, and 30 OL + 2L PEG. Preparation tolerance was evaluated with visual analog scale and preparation quality with the BBPS and HCS.

Results

Forty two patients were included. Twenty two (52.38%) were included with 4L PEG, and 20 (47.62%), with 30 OL + 2L PEG. 22 (52.38%) were men and 20 (47.62%) were women. The most frequent answer was partial tolerance in 18 (42.9%) and 23 (54.76%) patients, respectively, without statistical significance. The comparison in both preparations, 4L PEG had an average score of 6.04 points, and 30 OL + 2L PEG 6.65 points by BBPS (P = .9). HCS was successful in 35 patients (83.3%).

Conclusions

The administration of 30 OL + 2L PEG has similar cleansing results compared with the standard bowel preparation, which may be an alternative used in patients who are intolerable to high doses of liquids.
