Tolerance Of Colonoscopy Without Anesthesia: Any Predictive Factors?

Aims Tolerance of the colonoscopy is a determining factor of quality, especially since it is most often performed without anesthesia. The aim of our work was to assess the tolerance of colonoscopy in patients who presented to the endoscopy room and to determine the associated factors in order to better select the true candidates for colonoscopy under sedation.

Methods A prospective study was conducted, including consecutive patients consulting for endoscopy (July 2019-January 2020). Colonoscopy was performed without anesthesia. Tolerance was assessed by the visual analogue scale (VAS). Poor tolerance was estimated at VAS ≥ 7/10. In addition to patient‘s demographic characteristics, medical and surgical history, body mass index, indication for colonoscopy and quality of preparation assessed by Boston score were collected. For patients with irritable bowel syndrome, Francis score was calculated.

Results We collected 152 patients (median age: 60y.(28-89);74 females). The colonoscopy was performed to explore a transit disorder (constipation or diarrhea) in 50 % of cases. The average Boston score was 6/9 (3-9). The mean tolerance assessed by the VAS was 5/10 (2-10). One hundred and four patients (69 %) had well to moderate tolerability. Poor tolerability was associated with the following factors: history of abdominal-pelvic surgery (p = 0.006; OR = 2; 95 % CI (1-4)), diverticular disease (p = 0.02; OR = 3; 95 % CI (1-10)) and a Francis score of 245 (p = 0.027; OR = 8; 95 % CI (1-84)). Furthermore, no correlation was found between poor tolerance and the following factors: diabetes (p = 0.24), sex (p = 0.5), age (p = 0.09) and body mass index (p = 0.9).

Conclusions tolerance during live colonoscopy depended on a history of abdominal-pelvic surgery, diverticular disease and presence of irritable bowel syndrome with a high Francis score. Large scale taking into account these factors would better rationalize the indication of anesthesia during colonoscopy.
