High Definition Endoscopy With i-Scan for Small Colonic Polyp Evaluation: The HiScope Study
Colonic PolypsCurrent standard practice is to remove all colonic polyps found during colonoscopy as it has not been possible to distinguish between polyps with some malignant potential (adenomatous) and those with negligable malignant potential (non-adenomatous). Recent advances in endoscope imaging and technology have allowed endoscopists to distinguish between these two types of polyps by examining minute surface details. i-Scan is a new digital enhancement method that aims to enhance surface details and may enable similar accurate distinction between adenomatous and non-adenomatous polyps. Hypothesis: High definition white light endoscopy plus i-Scan improves diagnostic accuracy of in-vivo assessment of colonic polyps <10mm in size over high definition white light endoscopy alone.

Follow-Up Phone Calls After Colorectal Surgery
Colorectal SurgeryColorectal Neoplasms4 moreThe purpose of this study is to assess if follow-up telephone calls after colorectal surgery affects a patient's satisfaction, the outcome of their surgery, and their quality of life. In addition, readmissions, complications and emergency room visits can be tracked via these telephone calls, ensuring optimal communication between patients and the surgical office.

Influencing Factors in Patients With Colorectal and Gastric Polyps a Retrospective Study
PolypColonicThe identification of risk factors of colorectal/gastric polyp is more helpful for preventing colorectal cancer. And modifiable factors (such as high-fat diet, abnormal blood lipid, smoking, lack of exercise, obesity), and unmodifiable factors (including age, gender, race, familial adenomas, genetic)) can affect the risk of polyps. Thus early studying risk factors are the key to improving prognosis. what's more, early detection and timely treatment have important clinical significance for preventing and reducing the occurrence of gastrointestinal cancer.

Use of Accessory Device AmplifEYE During Average Risk Screening Colonoscopy to Increase Adenoma...
Colonic PolypsThe purpose of this investigator-initiated study is to determine whether the use of an accessory device called AmplifEYE can improve colonoscopy quality in patients who are undergoing average risk colorectal cancer screening. Primary end point is adenoma detection rates.

Cathartic-Free DECT Colonography for Detection of Colonic Polyps
Colonic PolypsAsses the clinical performance of dual-energy CTC for the detection of larger polyps 1 cm or larger without cathartic preparation.

The Effect of Music on Colonoscopy (MUSICOL)
Procedural AnxietyColon PolypColonoscopy is an essential tool for diagnostic evaluation for a wide range of gastrointestinal complaints and is considered the gold standard for colorectal cancer screening. This procedure is often associated with patient anxiety both prior to and during the procedure, as well as discomfort,which is managed with procedural sedation.Anticipation of an uncomfortable experience can deter patients from undergoing the procedure despite it being medically indicated. Music has a number of beneficial effects including improving senses of relaxation and well being. Use of music during colonoscopy is inconsistent and there are no society guidelines or recommendations regarding its use. The investigators hypothesize that music will improve the overall patient experience and enhance endoscopist performance.The investigators propose a randomized controlled trial to study effects of music on both the patient experience and endoscopist performance during colonoscopy. Eligible patients will be randomized to two groups: a "music group" and a "no music"control group.Patients in the music group will be asked for their preference of music to be played during their colonoscopy. For patients in the music group, this music will be played in the procedure room during the procedure, while those in the control group will have no music playing. Patient anxiety and pain will be assessed both before and after the procedure.Overall patient experience after the procedure will be assessed on a likert scale. The performance of the endoscopist will be assessed by measuring adenoma detection rate and adenomas per colonoscopy. Additional outcomes to be assessed include total procedure time and amount of sedation required.

Endoscopic Characteristics of Colonic Tumours
Colonic PolypColon CancerThe purpose is to investigate whether polyps that look different at colonoscopy, have formed via different mutations and have different risks of turning into cancer.

Evaluating the Cologuard Test for Use in Lynch Syndrome
Lynch SyndromeColorectal Cancer2 moreThis study is aiming to enroll 90 patients with genetically confirmed Lynch Syndrome (LS) from Geisinger's High Risk Colorectal Cancer Clinic (HRC). Upon enrollment in the study, a Cologuard test will be ordered and the results will be blinded until data analysis. Patients enrolled in the study will also undergo a colonoscopy as part of their routine HRC visit.
