Filter by:The success of colonoscopy is closely related to the quality of colonic preparation. However, data regarding colonoscopy preparations in the elderly (65 years older) are scarce. Split-dosage cathartic bowel preparation are currently suggested, whereas supporting evidence is lacking in this particular group of patients. Moreover, patient tolerability is a key factor for success of bowel preparation in the aged people. The purpose of this study is to compare the bowel cleansing efficacy and patient compliance of following bowel preparation methods prior to elective outpatient colonoscopy in the elderly: (1) standard preparation of 4 liters (L) PEG-3350 solution on the night before colonoscopy, (2) split-dose of 4L PEG-3350 solution, and (3) split-dose of reduced volume [2L] PEG-3350 containing ascorbic acid solution.
The purpose of this study is to determine residual gastric volume and residual gastric pH in patients undergoing combined EGD and colonoscopy comparing the standard single dose prep with the split dose bowel preparation and same day bowel preparations.
The purpose o this study is to evaluate the safety, tolerance and efficacy of BLI800 as a bowel preparation prior to colonoscopy in pediatric patients.
- Cold forceps polypectomy and hot biopsy forceps electrocauterization (HBF) are still widely used methods for endoscopic resection of diminutive colorectal polyps (DCPs)(polyps smaller than 5 mm). Jumbo forceps may be more effective in the removal of DCPs because of their larger size. - This was a prospective study of consecutive patients undergoing colonoscopy and found to have at least one diminutive polyp. One experienced endoscopist removed DCPs using either jumbo or hot biopsy forceps. - Aim was to evaluate the histological quality and adequacy of the DCPs resected using jumbo forceps in comparison with HBF.
After written consent for participating in clinical research studies, all clinical studies conducted to in the one day. The investigators will ask and record about bowel cleansing state in all patients who performed colonoscopy. There is no additional cost and the expected complications. Based on answer, the investigators will develop a prediction model for inadequate bowel preparation and prove validation. This model can take the additional measures to subjects predicting improper cleansing. It can contribute to improve the accuracy of the test and reduce the discomfort due to re-performing colonoscopy after re-preparation, as well as cost savings due to reduced frequency of re-colonoscopy Ultimately, it will be able to bring a improvement of the quality of management
The purpose of colonoscopy (colon examination with flexible tube and a camera) is to find early precancerous growth in the colon (polyps) and remove them before they turn into cancer. The doctor performing the procedure will first advance the colonoscope to the end of the colon (cecum) and then he will examine the colon for polyps while he is withdrawing the colonoscope. The period of time that the doctor spent examining the colon called "withdrawal time". Usually doctors will spend at least 6 minutes examining the colon after he reached the cecum. The investigators are proposing that dedicating half of the withdrawal time during colonoscopy in examining the right side of the colon, will increase the detection of polyps in the right side of the colon.
The purpose of this study is to determine whether the pattern of flavoring and drinking of laxatives for colonoscopy can improve the experience of patients when they are undergoing bowel preparation for the test. Investigators hypothesize that patients will have a better experience if patients taste the bowel preparation laxative with and without flavoring and then decide how they want to drink the rest of the laxative since taste preferences vary widely from person to person.
This study aims to compare a standard approach to bowel preparation for colonoscopy (using sodium picosulphate/magnesium citrate or 4lPEG) to an individualized approach where patients are assigned a specific regimen of either sodium picosulphate/magnesium citrate or 4lPEG depending on patient-related factors. The study aims to compare patient-related outcomes such as comfort levels during bowel cleansing and physician-related outcomes such as bowel prep quality in the two study groups.
The purpose of this study is to compare the efficacy of a low-volume bowel preparation versus a high-volume bowel preparation for bowel cleansing on hospitalized patients undergoing colonoscopies.
To access the efficacy of adding diphenhydramine as adjunct to improve sedation and to reduce the amount of standard sedatives used during colonoscopy in patients on chronic opioids.
