Active clinical trials for "Colonic Diseases"

The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.

The objective of this study is to confirm the sensitivity and specificity of a stool DNA test for detection of colorectal cancer and pre-cancer.

The purpose of this study is to determine: What quantity of bacteria is spilled into the abdomen during a colon resection If there is a correlation between the quantity and post-operative infection What intralumenal pressure is generated when testing the colonic anastomosis for air leak

It is hypothesized that primary care colonoscopists are able to achieve benchmarks in colonoscopy quality including cecal intubation and adenoma detection rates and serious adverse event rates. This prospective study is the first in depth analysis of the quality of colonoscopic procedures performed by primary care physicians at a provincial level in Canada. In addition, the APC Endo study is the first to directly examine both the quality of colonoscopy and patient satisfaction in the same study.

Up to now, many studies has showed that compared with air insufflation colonoscopy, water-related colonoscopy could shorten the cecal intubation time and relieve the pain of the patients,especially for training the beginners,the investigators conduct this study to preform the "air assisted" water injection colonoscopy in experienced endoscopists.

The primary objective of this study is to gather stool samples from subjects with inflammatory bowel disease (IBD) to be added to a test set of stool samples that will be utilized to help select molecular markers and determine the optimal sensitivity and specificity values for the Exact IBD-ACRN surveillance test for colorectal cancer (CRC).

Duplicated colon appendix are infrequent detected during surgical exploration. For Diagnosed cases, excision of the duplicated part is indispensable, due to risk of malignancy.

The aim of the study is to determine if more force is used during colonoscopy when patients receive monitored anesthesia with propofol versus conscious sedation. Force measurements will be performed using the colonoscopy force monitor (CFM). This device measures the magnitude and direction of force applied to the insertion tube of a standard colonoscope during colonoscopy.

Hartmann's procedure was described for the first time in 1921 as an alternative to abdominoperineal resection for the treatment of upper rectal tumours. Although Hartmann's procedure fell out of favour for rectal cancer after the introduction of restorative procedures, it remained the most common procedure in emergency setting for many years. Nowadays Hartmann's procedure is a useful procedure in selected cases e.g. severely ill patients with a high risk of anastomotic failure. However, restoring intestinal continuity for Hartmann patients is often associated with high morbidity, and about 70% will live with a permanent colostomy. Hartmann procedure' is a rapid and simple surgical technique intended to decrease perioperative morbidity and mortality. This technique is often performed by young surgeons Indeed, end colostomy may be necessary in situations where restoration of continuity is risky, either because of unfavorable local conditions or because a more definitive resection must be aborted due to hemodynamic instability. In the last decade the Hartmann's procedure has been revalued in many studies. In diverticular disease the results of DIVA arm of the LADIES trial showed that more patients in the primary anastomosis group were stoma free compared with patients in the Hartmann's procedure group. Other studies have observed no differences in major postoperative complications or postoperative mortality between patients undergoing primary anastomosis versus Hartmann's procedure. Hartmann's procedure reversals were associated with a higher risk of serious postoperative complications than were stoma reversals after primary anastomosis with ileostomy. Despite the growing evidence in favour of primary anastomosis and its inclusion as a valid treatment option for perforated diverticulitis or perforated sigmoid colon in recent clinical practice guidelines, some surgeons have been hesitant to undertake anastomosis in the setting of purulent or faecal contamination and continue to choose Hartmann's procedure to eliminate concerns about anastomotic leakage.
