Filter by: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.
The objectives of this Phase I study is to evaluate the safety and effectiveness of the endoscopic endodontic equipment device for root canal assistance treatment as well as to evaluate the ease of use of this device, by a surgeon experienced in endodontic treatment, in a true clinical setting.
Natural orifice translumenal endoscopic surgery (NOTES) has revolutionized the concept of minimally invasive surgery. NOTES is currently performed through transgastric or transvaginal approaches. The transvaginal approach is technically easier, but is only available to women. A transrectal approach has been proposed as a potential alternative to transvaginal NOTES for men. Fortunately, the technology to facilitate transrectal access and closure for NOTES has been in use for over twenty years, in the form of transanal endoscopic microsurgery (TEM) platforms. We hypothesize that transrectal NOTES appendectomy is feasible in humans using a flexible endoscope and a TEM platform to assist with transrectal access and closure. After a pre-clinical study involving 5 cadavers, we will perform a clinical study of 10 transrectal NOTES appendectomies in patients already scheduled to undergo laparoscopic total proctocolectomy or total abdominal colectomy. The tissues involved in the NOTES procedure will be removed as part of the patient's originally scheduled operation, reducing the risk of morbidity as a result of an inadequate transrectal closure or appendiceal stump leak. We will measure operative times, complication rates, peritoneal contamination, and assess the integrity of the rectotomy closures. We hope to show that transrectal NOTES appendectomy is clinically feasible in humans using a TEM platform.
The purpose of the study is to test the effect of a bowel preparation and boosts regimen on PillCam® procedure, colon cleanliness and capsule excretion time.
The purpose of this study was to assess the safety and efficacy of CNS 7056 as a procedural sedative at three dose levels compared to midazolam during a diagnostic upper GI endoscopy.
Refinements in laparoscopic surgery, coupled with advancements in therapeutic flexible endoscopy, have set the stage for surgery to move to even less invasive techniques to treat conditions in the GI tract and peritoneal cavity. Natural orifice translumenal endoscopic surgery (NOTES) offers a means of reducing and ultimately eliminating the need for abdominal incisions to gain access to the peritoneal cavity. In NOTES, a flexible endoscope and accessory instruments are inserted through a natural body orifice and passed through the wall of an organ to reach the abdominal cavity. By reducing or eliminating the need for abdominal incisions, NOTES may provide a least invasive surgical option that can reduce pain, recovery time, complications, and systemic inflammatory response when compared to a laparoscopic surgical approach. In this study, we propose to use the NOTES technique to eliminate the need for a 1.5-2.5 cm umbilical incision. Hypothesis 1: We hypothesize that a combined endoscopic and laparoscopic approach will be able to eliminate a 1.5 to 2.5 cm infraumbilical incision when performing a laparoscopic cholecystectomy. Hypothesis 2: Closure of the gastrotomy will be facilitated with the Ethicon TAS system.
Parents need understandable information in order to make appropriate choices for their child's health care. This is especially true when making decisions about invasive medical procedures. Parents need to understand what will happen, the risks involved, how these risks will be managed and what other options they have before they can decide what is best for their child. The present proposal involves the creation of a novel patient decision aid about the gastro endoscopy procedure, called a "scope." The purpose of the aid is to provide parents with information so they are able to discuss the options with their child's health care providers.
The main purposes of this study are to compare clinical outcomes of two groups of patients with similar medical conditions (one with non-variceal upper gastrointestinal (UGI) lesions such as ulcers and another group with varices or portal hypertensive lesions) who are treated either with current standard visually guided endoscopic treatment according to stigmata of hemorrhage or with endoscopic Doppler endoscopic ultrasound probe (DEP) monitoring of blood flow in the lesion.
There remains debate regarding whether small bowel cleansing is required prior to video capsule endoscopy, and if so, which method is best. This study prospectively tests cleansing with no preparation, preparation with picosalax, and preparation with polyethylene glycol.
Recent studies indicate that infusing 300 milliliters of water (in lieu of air) into the rectum and left colon through the colonoscope as it is being inserted during a colonoscopy examination can allow easier endoscope advancement. This method may prevent stretching of the colon, and ultimately reduce pain induced during colonoscopy. Improvements in patient comfort and cooperation, may increase the efficiency and success rate of complete colonoscopy. The purpose of the study is to test the efficacy of the water immersion technique in patients colonoscopy.
