Background and Objective: In order to reduce congestion one-day surgical preparation of patients to detection of colorectal abnormalities has to be developed. The purpose of this study was to comparison outcomes of quality of bowel preparation before colonoscopy between Inpatients and one day surgery patients.

Method: The research was a randomized controlled trial. All data collected from patient at Roi Et Hospital between May and June 2022. The study subjects were divided into 2 groups. Group 1 was 35 inpatients unts and group 2 was 35 patients with one-day surgery, of both 2 groups were positive for iFOBT. Descriptive statistics and Chi-square test were used for data analysis. The statistically significance was set at p < 0.05.

Results: In-patients were female 65.71%, mean age of 60.25 years, colon cleanliness good level 68.57%, colonoscopy found polyp 28.57%, hemorrhoid 5.71%, diverticulitis 17.14%, tubular adenoma 1.28%, and carcinoma 2.86% (1 patient). One-day surgery patients were female 60.00%, mean age of 59.22 years,  colon cleanliness good level 60.00%, colonoscopy found polyp 22.86 %, hemorrhoid 8.57%, diverticulitis 11.43%, tubular adenoma 5.71%. Comparing outcome of bowel preparation in colon cleanliness, colonoscopy time, and colonoscopy results of both groups were non-statistically significant (p > 0.05).

Conclusion: This study found that colon cleansing, time for colonoscopy, and colonoscopy results in both groups were not difference. Therefore, to reduce congestion, reduce days of admit, reduce the risk of nosocomial infection, saves patient and hospital cost patients who passed physical examination and can prepare themselves at home should encourage them to receive one-day surgery.
