Abdominal discomfort is of the most important patient interest when in an unsedated colonoscopy examination. Water method for colonoscopy examination has been studied widely and evidence showed effectiveness in reducing discomfort and increase cecal intubation time and increasing cecal intubation rates in unsedated patients. Our previous studies showed that water immersion method reduced the VAS score, accelerated the intubation time significantly without different changing cecal intubation rate. Previous right-sided vs. left-sided starting position colonoscopy study in sedated patients with air insufflation colonoscopy method showed that right-sided starting position improved the abdominal discomfort score and faster cecal intubation time. We want postulate that the right-sided starting position can also maximize the water method advantages in lowering the discomfort score, faster cecal intubation time and higher cecal intubation rates, and it will improve patient acceptance of water unsedated colonoscopy and willingness to repeat.
