South Korea: WingCap-assisted colonoscopy was more tolerable and effective than normal colonoscopy in improving adenoma detection rate (ADR) and adenoma per colonoscopy (APC), says a new study published in the journal Gastrointestinal Endoscopy.

Cap-assisted colonoscopy first appeared in Japan in the 1990s, and its use for diagnostic colonoscopy has gradually gained acceptance since then, aided by technical advancements and new devices demonstrating incremental value with respect to adenoma yield, a defined surrogate for colorectal cancer-related mortality.

WingCap is a unique distal connection device for a colonoscopy that combines a cap with a previously used mucosal exposure device, such as Endocuff or AmplifEye. As a result, Seung Wook Hong and colleagues undertook this study to see if WingCap-assisted colonoscopy may enhance adenoma detection rate and adenoma per colonoscopy while also shortening caecal intubation time compared to normal colonoscopy.

A randomized, single-center prospective, controlled study for outpatients aged 18 years was done for colonoscopy. The key result was ADR disparities with the help of WingCap. Secondary outcomes included APC and other quality measures during colonoscopies, such as caecal intubation and withdrawal times.

The key findings of this study were as follows:

1. A total of 537 individuals were randomly assigned to either WingCap-assisted or traditional colonoscopy.

2. Their average age was 59.3 years, and 48.5% of them were male.

3. The WingCap group had considerably greater ADR than the control group.

4. WingCap produced higher APC than the norm, particularly for non-pedunculated and small adenoma.

5. WingCap considerably boosted ADR and APC for novice endoscopists while having a little effect on expert endoscopists.

6. Caecal intubation and removal times did not differ between the two arms. WingCap was not related to any major adverse events.

In conclusion, the WingCap colonoscopy equipment proved successful in lowering ADRs and APC rates while avoiding significant side effects.
