Abstract

Background: Caecal intubation is an important measure of the quality of colonoscopy. Information on the effect of the time of colonoscopy on caecal intubation rate (CIR) is scarce. This study aimed to compare the CIR between morning and afternoon colonoscopies at the University College Hospital, Ibadan, Nigeria.

Methods: A descriptive study of consenting patients referred for colonoscopy at the endoscopy unit of the University College Hospital, Ibadan, from January 2016 to March 2017. Bowel preparation consisted of liquid diet and Epsom salt. Pre-medications were intravenous Midazolam 2.5-5 mg and Pentazocine 15-30 mg in titrated doses. Colonoscopy was performed using Olympus Exera III Videocolonoscope (CF HQ190L, Olympus UK). Morning procedures were those carried out between 8.30 am and 12.00 noon, while those after 12.00 noon were classified as afternoon procedures. Caecal intubation was considered successful when the medial wall of the caecum was visualized.

Results: Total of 177 colonoscopies were performed with 115 (65%) performed in the morning and 62 (35%) in the afternoon. In the morning, median age was 60 yrs, while in the afternoon, it was 61 yrs. Males (60.9% vs 58.1%) predominated in the morning, whereas females predominated in the afternoon (41.9% vs 39.1%), (p=0.72). In the morning, 100 (87%) patients had good/satisfactory bowel preparation, but 52 (83.9%) patients in the afternoon.(p=0.57). CIR was higher in the morning (90.4%), compared to afternoon (88.7%) (p=0.72).

Conclusion: There was no statistically significant difference between CIR in the morning and afternoon procedures.
