Brief summary
This study aims to compare the efficiency of two common procedures for the removal of colorectal polyps. Who is it for? You may be eligible to join this study if: - You are aged 18 years or above, - Are undergoing elective colonoscopy, - And have at least one colorectal polyp of size 9mm or less. Study details: Participants in this study will be randomly allocated (by chance) to one of two groups. Participants in one group will undergo conventional cold snare polypectomy. This involves inserting the polyp removal device (i.e. the snare) into the colonoscope channel for removing your polyp. Then removing the snare out of the colonoscope channel prior to retrieving your polyp. Participants in the other group will undergo snare-within-the-scope-channel (SWITCH) cold snare polypectomy. This involves leaving the polyp removal device (i.e. the snare) in the scope channel prior to and after removing your polyp, and during retrieval of your polyp. Participants will not know which group they are in until after the study is completed. Procedure time will be measured in all participants and compared across groups. This will enable us to determine which of the two procedures is more efficient.
Interventions
Interventional Procedure (Arm 1): Snare-WithIn-The-scope-CHannel (SWITCH) Cold Snare Polypectomy
In this arm, all polyps encountered during colonoscopy will be removed by SWITCH cold polypectomy technique. This involved advancement of the snare which is already in the scope channel, transecting the polyp (i.e. polypectomy), then partially withdrawing the snare into the channel (without removing the snare from the scope channel) prior to suctioning the polyp for retrieval. All further polyps enc
Interventional Procedure (Arm 1): Snare-WithIn-The-scope-CHannel (SWITCH) Cold Snare Polypectomy In this arm, all polyps encountered during colonoscopy will be removed by SWITCH cold polypectomy technique. This involved advancement of the snare which is already in the scope channel, transecting the polyp (i.e. polypectomy), then partially withdrawing the snare into the channel (without removing the snare from the scope channel) prior to suctioning the polyp for retrieval. All further polyps encountered in the same patient will be removed by the same technique. All procedures will be performed by 2 consultant gastroenterologists with expertise in therapeutic colonoscopy. The procedure duration is similar to any standard colonoscopy and is allocated half an hour slot in the weekday elective endoscopy list. Duration can vary depending on number of polyps encountered.
