Filter by:Recently colonoscopy has gained importance as screening programs for colon polyp, cancer and inflammatory bowel disease in the United States and other countries. The number of colonoscopy performed has been increased year by year. To make an increased compliance with colonoscopy in both screening and clinical surveillance programs, consideration of anxiety, shame and satisfaction in examinee is regarded to be important. During colonoscopy patients wear conventional single pants where there is no hole for insertion of scope. Patients take off the conventional single pants below the buttocks and expose their buttocks and perianal area during colonoscopy. Exposing perianal and perineal area during colonoscopy can make patients feel shameful and anxious and diminish satisfaction of colonoscopy. Recently considering the factors affecting satisfaction has been regarded to be important because patient satisfaction could be one of the quality indicators for colonoscopy. To diminish shame and anxiety by exposing perianal and perineal area of patients wearing conventional single pants during colonoscopy, we developed novel double pants with a hole in inner pants. Novel double pants are composed of double fabrics from hip to thigh and single fabric under the thigh such as common pants. In the inner pants of double pants, there is a hole for insertion of scope. The hole is 25 cm wide and 15 cm long. The outer pants are same as conventional single pants. If the patients dropped outer pants below hips, only hip and perianal area are exposed through the hole (25cm*15 cm) for insertion of scope without dropping inner pants. Therefore novel double pants minimized the exposed area of hips than conventional single pants because hips are exposed only the hole of inner pants. Smaller exposed area of hips by novel double pants can minimized the shame and anxiety by diminishing exposing perianal and perineal area during colonoscopy. Therefore advantage of novel double pants is decreasing shame and anxiety and increasing satisfaction by minimizing the exposed area of perianal and perineal area compared with conventional single pants. This study is a randomized controlled study. The investigators will survey the examinees older than 20 years who performed the colonoscopy at Severance Hospital from Feb. 2012 to Jul. 2012 to compare the effect on the satisfaction, shame, and anxiety during colonoscopy between the two groups.
The investigators propose to conduct a prospective study of a widely used bowel preparation regimen (polyethylene glycol 3350 + a sports drink) on pediatric patients who undergo a colonoscopy performed by the pediatric gastroenterology service at WRAMC/WRNMMC between 1 Sep 2010 and 31 Dec 2011. This study will involve the following: determine efficacy of the cleanout, assess tolerability and acceptance of the regimen, determine an appropriate duration to complete the regimen and assess for any electrolyte changes or side effects.
In bowel preparation using split dose PEG, various adjuncts to colonic cleansing were proposed to improve colonic preparation cleansing. Prokinetics, as an adjunct, was included in a few studies. The investigators study was to show that sufficient dosage of prokinetics added to split dose of PEG improves the state of bowel preparation.
It is hypothesized that PEG 2L with citrate and simeticone plus bisacodyl will have similar bowel cleansing efficacy versus PEG 2L with ascorbate. Safety, tolerability, acceptance and compliance of the two reduced volume PEG-based bowel preparation will be also compared.
The objective of this study is to compare the safety, tolerance and efficacy of BLI800 (approved and investigational regimens) to an approved control preparation as bowel preparations prior to colonoscopy in adult patients, particularly including the elderly and those with renal and/or hepatic impairment.
An excellent bowel cleansing is mandatory to increase the diagnostic accuracy of colonoscopy. Failure to adequately cleanse the bowel for colonoscopy can lead to missed lesions, prolonged procedure duration and repeated procedures at earlier intervals. Emerging solid evidence is pointing out the need of switching from preparation the day before to regimens in which half or even more of the preparation is administered the same day of the procedure, which have extensively demonstrated to provide a significantly better cleansing, being well tolerated. Preparation can be fully administered the same day for afternoon procedures, whereas split-dose regimens fit better with morning colonoscopies. However, the ideal regimen for early morning colonoscopies is still to be elucidated. The second part of the preparation for these patients is usually recommended to be taken during sleeping time (2-3 am) on the belief that intake of fluids should be completely halted at least four hours prior to the colonoscopy procedure Sodium picosulphate is a unique orange-flavoured cleansing agent dosed as two powder sachets. Mayor advantages in comparison with current alternatives are relatively small volumes (each sachet is mixed with only 150-250 mL of water) and a more pleasant taste. It provides similar bowel cleansing than sodium phosphate and polyethylene glycol solutions administered the day before. Nonetheless, focus on split-dose regimens has been set on several polyethylene glycol (either high-volume or low-volume) regimens, but no data are available for split-dose sodium-picosulphate regarding colonoscopy in adults. The aim of the study is to evaluate the efficacy and safety of a sodium-picosulphate low-volume split-dose regimen, in which the second-half of the preparation and fluids intake are allowed until 2 hours for early morning colonoscopies and until 2-6 hours for morning colonoscopies, comparing this split-dose regimen with standard cleansing the day before with sodium picosulphate/magnesium citrate.
Colonoscopy is an important procedure for diagnosing and treating diseases of the colon. In Canada, up to 13% all colonoscopies do not examine the full colon and are therefore incomplete. Incomplete colonoscopies happen for a number of reasons but are often due to twists and turns in the colon that make the colonoscopy difficult to perform and uncomfortable for the patient. This randomized study is being done to test a new colonoscopy system called the Scope Guide that shows an exact 3-dimensional picture of how the colonoscopy is positioned in the patient's abdomen. We hypothesize that the use of the Scope Guide for colonoscopy will improve measures of colonoscopy quality including rate of complete examination, patient comfort, polyp detection rate, insertion time, amount of sedation required, and need for abdominal compression.
Purpose of study: To evaluate the efficacy of PillCam Colon2 in subjects with an incomplete standard colonoscopy Study design: 4 centers, prospective, cohort study Number of subjects: 74 subjects Subject population: Patients that are indicated for colonoscopy, who are suspected or known to suffer from colonic diseases and had an incomplete standard colonoscopy Control group: None Procedure Duration: Approximately 10-12 hours Duration of Follow up: One week follow up Duration of study: 12 months Primary objectives: Evaluation of the efficacy of PillCam Colon2 to visualize the colon segment not reached by an incomplete standard colonoscopy Evaluation of distribution of excretion of capsules over time
In colorectal cancer screening era a huge burden of medical resources has been applied to surveillance. Although the adherence to post-polipectomy recommendations is a advocated as a mainstay for quality assurance colonoscopy programs, prospective data on appropriateness of surveillance are lacking. The aim of present study was to evaluate the percentage of subjects in which timing of surveillance colonoscopy in practice agrees with that recommended by guidelines and to identify factors associated to the appropriateness of surveillance.
The investigators wish to compare the efficacy and patient tolerability of a preparation consisting of 2L Golytely (PEG + electrolytes) plus 15mg of bisacodyl vs the standard preparation of 4L Golytely. The investigators hypothesize that 2L Golytely with 15mg bisacodyl will show similar bowel cleansing efficacy while offering better tolerability.
