Aims In March 2020, COVID-19 has been declared as a pandemic, resulting in modulation
of endoscopic activity and enhancement of personal protective equipment (PPE) when
performing colonoscopy. Recently, it has been shown that such PPE interferes with
visual and auditory perception. Our aim was to evaluate if PPE may negatively impact
colonoscopy quality.
Methods Cross-sectional retrospective study comparing colonoscopy quality indicators between
elective outpatient non-therapeutic colonoscopies performed between April and May
2019 and 2020 (lockdown period). We included patients aged > 50 years old and excluded
patients with inflammatory bowel disease, history of colon surgery or cancer (CRC).
300 colonoscopies were randomly and evenly selected from the two groups. Cecal intubation
rate (CIR), adenoma detection rate (ADR), mean number of polyps, adenomas and serrated
sessile lesions (SSL) per colonoscopy were assessed and compared.
Results Groups were similar regarding gender, mean age and exam indication. Indications for
colonoscopy were classified as screening (25 % vs 22 %), diagnosis (41 % vs 48 %)
and post-polypectomy surveillance (33 % vs 29 %). There was no significant difference
in CIR (90 % vs 88 %), adequate bowel preparation (70.5 % vs 70.6 %, p = 0.970) and
procedure duration. Polyp, adenoma and SSL detection rates were similar in both groups
(66.7 % vs 66.7 %, p = 0.999; 57.4 % vs 51.4 %, p = 0.609; 5.5 % vs 9.5 %, p 0.173).
There was no difference in the mean number of polyps and adenomas. For polyps < 5
mm the mean number was lower in 2020 (1.59 vs 1.09, p = 0,028). There was no difference
in high-risk patients (19.3 % vs 21.1 % (p = 0.143) and CRC (4.7 % vs 2 %, p = 0.335).
The ADR difference remained non-significant, after adjusting (multivariate analysis)
for bowel preparation, intubation detection rate, endoscopist and exam duration.
Conclusions In our study, the use of PPE did not influence key performance measures of colonoscopy
quality.
