Filter by:This was a randomized, endoscopists' blinded comparison of bowel colonoscopy cleansing and tolerability of a prespecified low-residue diet compared with a clear liquid diet and Polyethylene Glycol bowel preparation. Outcome measures included efficacy of bowel preparation, patient preparation tolerability and side-effects.
The aim of the present study is to compare polyp detection rates of LCI with high-definition white light endoscopy (HD-WLE) in patients with Lynch syndrome in a parallel, international, multicenter, randomized controlled colonoscopy trial
This is a prospective study comparing endocuff-assisted colonoscopy to standard colonoscopy. The goal of this study is to evaluate the interest of second-generation Endocuff Vision (ECV) to improve Adenoma detection rate and / or Polyp detection rate as the Mean Number of Polyps (average number of polyps) in routine colonoscopy. This is a prospective comparative study, on 2000 patients, 1000 in each group (with and without ECV)
Background 2L polyethylene glycol plus ascorbic acid (PEGA) is known to be as effective as standard 4L polyethylene glycol for bowel preparation. However, the volume of this regimen is still large. Therefore, the present investigators evaluated the potential of 1L PEGA with prepackaged low-residue diet (PLD) for an alternative to 2L PEGA. Aim: To evaluate efficacy of 1L PEG with ascorbic acid combined with prepackaged low-residue diet as bowel preparation for colonoscopy. Methods: The subjects were randomly assigned to either groups. PEGA group received 2L PEGA split regimen. PLD group received PLD on the day preceding colonoscopy and 1L PEGA on the morning of colonoscopy. One blinded physician performed colonoscopy and evaluated the degree of bowel preparation using Boston bowel preparation score (BBPS). A questionnaire regarding tolerability and safety were also gathered.
The objective of this study is to evaluate the safety and efficacy of BLI4900 as a bowel preparation prior to colonoscopy in adult patients.
This prospective randomized controlled trial compared integrated water jet channel colonoscopy with traditional accessory channel colonoscopy in cecal insertion time among patients undergoing WE method colonoscopy.
The objective of this study is to compare the safety and efficacy of BLI4700 bowel preparation to an FDA-approved bowel preparation as 2-day, split-dose bowel preparations prior to colonoscopy in adult patients.
Patients with longstanding ulcerative colitis (inflammatory bowel disease, IBD) have increased risk of developing colorectal cancer (CRC) when compared with that of the general population. Therefore patients with longstanding colitis undergo regular screening colonoscopy at varied time intervals depending on their individual risk. This is thought to detect early mucosal (interior bowel lining) abnormalities, known as dysplasia, which can progress to CRC. Until recently, IBD surveillance has relied upon colonoscopy with multiple (at least 33) random biopsies of the bowel lining to detect dysplasia, but now international guidelines recommended a technique called chromoendoscopy. Chromoendoscopy involves applying a dye, called indigo-carmine, to the bowel lining whilst performing colonoscopy which highlights more subtle abnormalities, therefore increasing dysplasia detection rate. There is no standard international concentration of the dye spray used during chromoendoscopy. Studies have used different concentrations of indigo-carmine dye ranging from 0.1 to 0.4%. We have recently shown that 0.2% dye improves detection rates compared to high definition white light. The recent international SCENIC guidelines suggest using 0.03% indigo-carmine via a foot pump. However there are no trials comparing the two methods and no previous trials have used the 0.03%. We therefore aim to perform a randomised control trial, comparing 0.03% indigo-carmine dye versus 0.2% in detecting dysplasia in patients undergoing surveillance colonoscopy in IBD. Any lesions seen will assessed using standard endoscopic appearance but also using optical biopsy forceps to further characterise the lesion, then manage the lesion as standard guidelines. We will also take two additional rectal biopsies, which will be snap frozen in liquid nitrogen and then studied using Raman Spectroscopy, Infra Red spectroscopy and electrochemical impedance to develop optical markers to identify patients at higher risk of dysplasia.
This study compares a colonoscopy preparation composed of magnesium citrate capsules to a preparation of polyethylene glycol solution. The hypothesis is that the magnesium citrate capsules work as well and are better liked by patients due to the lack of taste.
This is a randomized controlled trial designed to assess the efficacy of a novel smartphone application as an automated reminder tool in improving the quality of bowel preparation for patients undergoing outpatient colonoscopies. The investigators will be comparing the smartphone application to traditional instructions for bowel preparation. The quality of bowel preparation will be assessed using the Ottawa and Aronchick bowel preparation scales.
