Repeated Forward-View Examination Improves Detection of Missed Polyps in the Right-Sided Colon

Aims Right colon polyps can be missed especially when they are located on the backs of haustral folds. The aim of this study was to analyze the efficacy of an additional observation using white light imaging (WLI) for detecting polyps.

Methods We enrolled patients undergoing colonoscopy from June to October 2020 in our endoscopy unit. All colonoscopies were perfomed by the same endoscopist. Patients were divided into 2 groups. In all patients, the cecum and ascending colon were observed with white light imaging (WLI) first. In Groupe 2, the colonoscope was inserted again, and the cecum and ascending colon were observed for an additional one minute. Polyps detection rate (PDR) was examined in both groups.

Results One hundred and twelve patients were included in our study. The mean age was 56.2 years [18,83]. The sex ratio was 1.43. The most frequent indications for colonoscopy were transit disorders such as constipation and diarrhea in 17,8 %, digestive bleeding in 13,4 % and iron deficiency anemia in 10,7 % of cases. The mean Boston score was 6/9. Groupe 1 included 52 patients and groupe 2 included 59 patients. The average withdrawel time was 12 minutes. In the first group, PDR was 17,3 %. In the second group, PDR was 44 %. (p=0,002). No severe adverse events occured during the repeated forward-view withdrawal.

Conclusions According to our results, the repeated forward-view examination in the right colon significantly imporves polyps detection rate with no additional side effects.
