Endocuff-Assisted versus Cap-Assisted Colonoscopy Performed by Trainees: A Retrospective Study

Abstract

Background/Aims: The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The efficacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the efficacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the efficacy between EAC and CAC in trainees. Methods: This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups. Results: The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group. Conclusions: Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees. Clin

Endocuff-assisted versus Cap-assisted Colonoscopy in Increasing Adenoma Detection Rate. A Meta-analysis

“…This finding supports the evidence of a higher detection with endocuff for smaller lesions, which are more likely to be missed in particular by non-expert endoscopists, and a greater overall number of polyps diagnosed as compared to capassisted colonoscopy. This aspect suggests a higher anticipated magnitude of benefit particularly for low-performing endoscopists (lower baseline ADR), as suggested by recent retrospective reports [25], whereas the improvement might be only marginal in expert operators. Third, the procedural characteristics do not seem to be influenced by the use of a specific add-on device over the other as both cecal intubation rate and insertion time were comparable in the two groups.…”

Endocuff‐assisted colonoscopy versus cap‐assisted colonoscopy for adenoma detection rate: A meta‐analysis of randomized controlled trials

“…Those comparing EAC with standard colonoscopy have shown a more consistent improvement in ADR than those of CAC. A recent published retrospective study also suggested that EAC exhibited increased ADR compared with CAC when performed by trainees 29 . In our meta‐analysis, only one study included trainees, which may reduce the ADR difference between the two groups.…”

Therefore, further evidence and more clinical trials are still need to compare ADR between EAC and CAC.…”
