Comparing Colon Capsule Endoscopy To Colonoscopy; A Symptomatic Patient’s Perspective

Abstract

Introduction:Colon Capsule Endoscopy (CCE) has proven efficacy in a variety of gastrointestinal diseases. Few studies have assessed patient-reported outcomes and preference between colonoscopy and CCE.Aims:To identify comfort scores and patient preferences between CCE and colonoscopy.Methods:Patients from our centre who had both a CCE and colonoscopy within a 12-month period were identified. We performed over-the-phone interviews focused on satisfaction, comfort, and overall preference with a 10-point Likert scale. Electronic records were reviewed; reported Modified-Gloucester-Comfort-Scale (GCS) score, sedation, bowel preparation and endoscopist grade were documented. Data was compared between procedures. A Fishers exact test was used to compare proportions and a Student t-test was used to compare means, a p < 0.05 was considered significant.Results:In all, 40 patients were identified, 57.5% (23/40) were female and the mean age was 48 years (24 – 78). All patients were referred for investigation of lower gastrointestinal symptoms as part of an ongoing study (1).There was a significance difference in mean comfort (9.2 vs 6.7, p<0.0001, 95% CI -3.51 to -1.44) but not satisfaction (8.3 vs 7.7, p=0.2, 95% CI -1.48 to 0.33) between CCE and colonoscopy. Main cause of dissatisfaction with CCE was bowel preparation and for colonoscopy was discomfort. Age and gender were not found to be variables. The correlation between GCS and patient reported values was weak (R = -0.28).Overall, 77.5% (31/40) of patients would prefer a CCE if they required further bowel investigation. Of these, 77.4% (24/31) preferred a CCE despite the potential need for follow-up colonoscopy.Conclusions:CCE has a high satisfaction rating (8.3 vs 7.7) and has a higher patient reported comfort rating (9.2 vs 6.7) than colonoscopy. Studies have confirmed CCE and colonoscopy have equivalent diagnostic yields. The majority of patients in our cohort prefer CCE to colonoscopy. CCE should be considered as an alternative to colonoscopy in selected individuals.

Possibilities of capsule endoscopy in colorectal cancer screening

“…Капсульная эндоскопия, по данным литературы, имеет высокую точность в обнаружении эпителиальных новообразований толстой кишки и колоректального рака, поэтому при выборе метода обследования толстого кишечника следует учитывать предпочтения пациента [6]. При опросе пациентов, которым в течение года были выполнены капсульная и обычная колоноскопия, получено, что 31 (77,5%) пациентов предпочли бы капсульное исследование, если бы им требовалось дальнейшее наблюдение кишечника [7]. Стоит отметить удобство применения капсульной эндоскопии для скрининга колоректального рака в отдаленных регионах, так как этап подготовки и процесс исследования не требует присутствия врача-эндоскописта и может быть проведен средним медицинским персоналом, либо участковым терапевтом.…”

Artificial Intelligence to Improve Polyp Detection and Screening Time in Colon Capsule Endoscopy

“…Among those alternatives, CCE has proven to be one of the most safe and effective tools, with an accuracy very similar to that of traditional colonoscopies 12 . It is less invasive for the patient 13 , it does not cause discomfort during the procedure (only minimal discomfort before the procedure due to required bowel preparation 13 ) and no anesthesia is needed. However, the reading of CCE is time-consuming and requires qualified medical personnel [14][15][16] .…”
