Brief Summary:
The goal of this trial is to evaluate whether water exchange colonoscopy and CO2-insufflation colonoscopy with an abdominal compression device Maxbelt me3 type Nippon Sigmax Co Tokyo Japan can achieve a significantly lower proportion of patients requiring manual abdominal pressure during colonoscopic insertion compared with CO2 insufflation alone
Detailed Description:
This will be a three-arm multicenter parallel randomized controlled trial RCT designed to compare the frequency of ancillary manual assistance abdominal pressure andor position change between CO2-insufflation colonoscopy with Maxbelt intervention group CO2-insufflation colonoscopy with sham device sham control group and water exchange WE colonoscopy WE group Enrolled patients will be randomized in a 111 ratio to either the intervention sham control or WE group This will be a comparison of three different methods CO2 with interventional device CO2 with sham device WE to see which one is better at decreasing the need for manual assistance by endoscopy staff during colonoscopic insertion
This study will be conducted in two hospitals in Taiwan Evergreen General Hospital at Taoyuan and E-Da Dachange Hospital at Kaohsiung The Sepulveda Ambulatory Care Center VAGLAHS UCLA in the USA will be a non-recruiting participating site This planned RCT will span 30 months from June 2024 to November 2026 including 3 months for the initial setup and 3 months for the final analysis The study site possesses state-of-the-art colonoscopy equipment setups and the investigators are WE colonoscopy research experts
Patients aged 45-75 yo at average risk of colorectal cancer who are willing to participate will sign an informed consent before starting the colonoscopy procedure Separate parallel randomization will be set up at each site stratified by investigator and type of colonoscopy screening surveillance or positive fecal immunochemical test result Mode of sedation will include conscious sedation fentanyl plus midazolam or full sedation propofol with fentanyl plus midazolam Randomization will be carried out by computer-generated sequences using a block design four participants per block
CO2 with interventional device group The Maxbelt will be applied around the circumference of the lower abdomen just below the umbilicus based on patients abdominal circumference Five sizes of Maxbelt will be employed in this study XS-size for 55-65 cm circumference S-size for 65-75 cm circumference M-size for 75-85 cm circumference L-size for 85-95 cm circumference and XL-size for 95-105 cm circumference Once applied participants will be asked to assess and confirm that the belt is fastened tightly but not uncomfortably
CO2 with sham device group A two-size larger Maxbelt with loose fitting will be used as a sham device L-size will be used for 55-71 cm circumference XL-size will be used for 72-88 cm circumference and 2 XL-size will be used for 89-105 cm circumference
WE group The air pump will be turned off during the insertion phase of colonoscopy while the colon is irrigated with warm-to-touch distilled water or half normal saline using a flushing pump The WE approach involves the simultaneous infusion of water to facilitate luminal expansion and suction of unclean water during insertion
