Introduction
Colonoscopy is considered the gold standard for colorectal cancer screening. Panoramic colonoscopy offers better visualization to decrease the adenoma miss rate.

Aim
To assess the influence of 330° panoramic view colonoscopy on adenoma and polyp detection rate, cecal intubation time, and examiner’s comfort.

Material and methods
The study enrolled 421 patients aged 18–80 years who were eligible for colonoscopy screening. Patients with prior abdominal surgery, inflammatory bowel disease or after colorectal resections were excluded from the study. Patients were randomized to either standard frontal view (SFV) (Olympus Evis Exera III 190 CF-HQ190L) or the panoramic view colonoscopy (PVC) (FUSE CDVL slim c38). The study was approved by the local bioethics committee and registered at ClinicalTrial.gov (NCT02929381).

Results
There were 214 patients examined with SFV and 207 with PVC. The mean age of patients was 64 ±12.26 years. The two groups were comparable. The median cecal intubation time was 234 s with SFV vs. 311 s with PVC (p < 0.001). There were no significant differences in CIR or withdrawal time. PVC made it possible to discover more diverticula in the ascending colon (p = 0.009). PDR with SFV was 34.6% and 40.1% with PVC (p = 0.242). A higher number of polyps was found in the transverse colon in the PVC group (p = 0.006). ADR and advanced ADR (aADR) in both groups were similar (26.4% vs. 27.1% and 14, 2% vs. 13.9%).

Conclusions
Colonoscopy with wide-angle endoscopes lasts longer and allows for the detection of more polyps and diverticula without affecting ADR and aADR. Our study did not reveal the superiority of wide-angle colonoscopy in colorectal cancer screening
