BACKGROUND Flexible sigmoidoscopy is indicated for colorectal cancer screening. The decision about who needs total colonoscopy based on distal findings is still controversial because of the uncertainty of the associations between distal and proximal findings. AIM The purpose of the study was to characterize distal findings in patients with total colonoscopy, to investigate its importance as m...
BACKGROUND/AIMS There is lack of consensus on the optimal time allotted for colonoscopy, which increases patient wait times. Our aim was to identify and quantify the individual pre-procedural factors that determine the total procedure time (TPT) of colonoscopy. METHODS This retrospective study involved 4,494 subjects, undergoing outpatient colonoscopy. Effects of age, sex, body mass index, ab...
Bowel preparation methods for total colonoscopy in children generally involve whole gut irrigation with electrolyte lavage solutions, which in most children will require hospitalisation for nasogastric tube administration. The aim of the study was to determine the efficacy of oral bisacodyl combined with a single phosphate enema as a bowel preparation regimen in children. In an open prospective...
AIM To assess the prevalence and location of advanced neoplasia in patients undergoing colonoscopy, and to compare the yield per indication. METHODS In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland), data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neop...
CONTEXT Conventional colonoscopy is the best available method for detection of colorectal cancer; however, it is invasive and not without risk. Computed tomographic colonography (CTC), also known as virtual colonoscopy, has been reported to be reasonably accurate in the diagnosis of colorectal neoplasia in studies performed at expert centers. OBJECTIVE To assess the accuracy of CTC in a large...
PURPOSE To prospectively assess and compare perceptions of and preferences for computed tomographic (CT) colonography, colonoscopy, and double-contrast barium enema examination (DCBE) by asymptomatic patients undergoing colorectal cancer screening. MATERIALS AND METHODS A total of 696 asymptomatic patients at higher-than-average risk undergoing colorectal cancer screening were consecutively r...
We can supplement the clinical value of an optical colonoscopy procedure if we can continuously co-align corresponding virtual colonoscopy (from preoperative X-ray CT exam) and optical colonoscopy images. In this work, we demonstrate a computer vision algorithm based on optical flow to compute egomotion from live colonoscopy video, which is then used to navigate and visualize the corresponding ...
Background: Diagnosis and treating patients with chronic diarrhea are challenging due to broad differential diagnoses. An adequate examination leads a specific diagnosis appropriate management. Colonoscopy biopsy is indicated establish etiologies. No previous data demonstrated the colonoscopy histology findings in at Dr. Hasan Sadikin Bandung General Hospital, main referral hospital West Java. ...
Objective: To compare the outcome of consumption a single versus split-dose polyethylene glycol electrolyte solution in patients undergoing colonoscopy morning. Methodology: A randomised controlled trial was conducted at Department Gastroenterology, Sir Ganga Ram Hospital, Lahore, from April to July 2021. total 274 colonoscopy, who fulfilled selection criteria were included through "non-probabi...
GOALS To test the hypothesis that the use of a low-residue breakfast (LRB) the day prior to colonoscopy was not inferior to consuming clear fluids alone (CFD) in patients undergoing outpatient colonoscopy with a polyethylene glycol (PEG) bowel preparation. BACKGROUND Optimal colon cleansing is essential for complete visualisation of the mucosa during colonoscopy. Few studies have examined the...
