Description
Ying-Ju Chao and colleagues tested in 2026 whether flushing the colon with water during colonoscopy finds more precancerous growths in everyday practice. Trials had already favoured the water exchange technique over the usual air inflation, yet busy real-world clinics might see different results. The team studied outpatient procedures at a high-volume Taiwanese centre.
After matching, each group held well over two thousand procedures. Water exchange lifted the adenoma detection rate by fourteen percentage points, with the biggest gain in the right side of the colon, and it also found more large adenomas and serrated lesions. Bowel cleanliness improved as well. The trade-off was time, with procedures lasting several minutes longer, mostly during insertion. Endoscopy units gain practical evidence for weighing detection gains against slower throughput.
