Filter by:This study aims to assess the effect, if any, on the adenoma detection rate of BowelScope bowel cancer screening flexible sigmoidoscopies by using the Endocuff Vision device.
A randomized controlled multicenter trial on the usefulness of intraoperative angiography with indocyanine green to assess anastomosis perfusion in patients who undergo laparoscopic rectal resection or left colectomy.
This study tests biopsy and tissue from patients who have been treated for primary rectal cancer at the Royal Marsden Hospital between 2011 and 2013, who have an mrTRG score at post-chemoradiotherapy MRI. It is a retrospective pilot study to determine the apoptotic and proliferative index count pre and post chemoradiotherapy.
3D high resolution anorectal manometry (3DHRAM) is the most precise tool to assess function and 3D topographic picture of pressures along the anal canal. Until now, it has been used only in adult population to evaluate defecatory disorders. Congenital anorectal disorders are severe conditions and may present wide spectrum of symptoms from gastrointestinal tract. The usefulness of the 3DHRAM hasn't been evaluated in children after surgery for anorectal disorders such as Hirschsprung's disease and anorectal malformations. It may help for better understanding of pathophysiology of anorectal area and allow for planning improved procedures in these patients. Moreover, the investigators study may elucidate the real usefulness of the procedure in management of disorders of gastrointestinal tract in pediatric population.
Early mobilization (i.e. initiation of out of bed activities from the day of surgery) is considered an important component of postoperative care after colorectal surgery. Having a health professional dedicated to facilitate early mobilization has the potential to enhance postoperative recovery by preventing the negative effects of prolonged bed rest (e.g. increased risk for complications, muscle loss, deconditioning and functional decline); however, the need to implement this resource-intensive approach is not evidence based. This study aims to contribute evidence about the role of facilitated early mobilization as a strategy to enhance recovery after colorectal surgery.
The purpose of this study is to establish a reliable method for detection of rectal cancer patients with aggressive tumor at risk of metastatic disease and death by functional MRI.
Ano-rectal manometry is indicative in patients with either fecal incontinence or constipation. Recently anorectal 3D- high resolution manometry has been developed. Pressure variations are measured circumferentially along the anal canal. It may allow a better understanding of anorectal disorders by displaying anal pressure asymmetry and it could be useful to assess the functional anatomy of the pelvic floor better than conventional manometry.
The purpose of this study is to determine: 1. What quantity of bacteria is spilled into the abdomen during a colon resection 2. If there is a correlation between the quantity and post-operative infection 3. What intralumenal pressure is generated when testing the colonic anastomosis for air leak
The purpose of this research is to compare two different standard of care surgical methods for the following large bowel (colon) procedures: laparoscopic right colectomy, total colectomy, and left colectomy. The study will compare electrocautery, used with surgical clips and/or surgical staplers, and the Ligasure vessel sealer. The investigators will be looking at which procedure is faster and more cost efficient and the investigators will calculate hospital expenses for the two groups to make comparisons.
