BACKGROUND: Water exchange colonoscopy has been reported to reduce examination discomfort and to provide salvage cleansing in unsedated or minimally sedated patients. The prolonged insertion time and perceived difficulty of insertion associated with water exchange have been cited as a barrier to its widespread use. AIM: To assess the feasibility of learning and using the water exchange method of colonoscopy in a U.S. community practice setting. SETTING: Quality improvement program in nonacademic community endoscopy centers...

The growing popularity of water immersion is supported by its long history as an adjunct to air insufflation; after facilitating colonoscope passage, the infused water is conveniently removed during withdrawal. Water exchange, a modification of water immersion to minimize discomfort in scheduled unsedated patients in the U.S. is new. Even though it may be superior in reducing pain and increasing adenoma detection, the paradigm shift to complete exclusion of air during insertion necessitates removal of infused water containing residual feces, a step often perceived as laborious and time-consuming...

BACKGROUND & AIMS: Colonoscopy plays an important and central role in current colorectal cancer screening and prevention programs, but it is an imperfect tool. Adjunct techniques may help improve the performance of colonoscopy to increase the detection of polyps with neoplastic potential. This study investigates the novel approach of combined water-exchange and cap-assisted colonoscopy (WCC) and its impact on adenoma detection. METHODS: A single-center single-colonoscopist consecutive group observational study to compare WCC with conventional air insufflation colonoscopy was performed...

PURPOSE: Chromoendoscopy with dye spray and the water method both increase adenoma detection. HYPOTHESIS: Adding indigocarmine to the water method will enhance further the effectiveness of the latter in adenoma detection. METHODS: Screening colonoscopy was performed with the water method (control) or with 0.008% indigocarmine added (study) by two endoscopists. Randomization was based on computer-generated codes contained in blocks of pre-arranged opaque sealed envelopes...

BACKGROUND: The methods for preventing post-polypectomy bleeding (PPB) are not standardised and there are groups that use hemoclips for this purpose. OBJECTIVE: To study whether the use of hemoclips reduces PPB complications. MATERIALS AND METHODS: Prospective, randomised study of patients with pedunculated polyps larger than 10 mm. The patients were included in two groups (hemoclip before polypectomy -HC- and standard polypectomy -SP-). This study has been registered with the trial registration number NCT01565993...

The pathologic potential of gastric inlet patches is now being recognized. A recent adult study has shown the effectiveness of argon plasma coagulation in ablating the patch and the associated symptoms. There are no reports of ablation in children. We report a case series of successful argon plasma coagulation of gastric inlet patches and their symptoms in 5 children.

BACKGROUND: Diverticulosis is a common finding in patients undergoing colonoscopy. The effect of colonic diverticulosis on the colorectal adenoma detection rate (ADR) and other colonoscopy quality indicators remains unclear. OBJECTIVES: To determine if colonic diverticulosis is associated with differences in (1) colorectal ADR and (2) other quality indicators and operating characteristics in patients undergoing first-time screening colonoscopy. METHODS: Retrospective cohort study conducted at an outpatient surgical center affiliated with an academic medical center...
