Filter by:A surgical intervention might be highly variable amongst surgeons and centers. This variability has a potential relevance concerning clinical outcomes. For right-sided colon cancer, the laparoscopic right hemicolectomy (LRHC) knows substantial variation. Especially since the surgical technique has been evolving during the latest decade with the introduction of intracorporeal anastomosis, a dissection technique within the correct embryological planes (complete mesocolic excision) and central vascular ligation of the segmental branches at its origin, resulting in an optimal lymph node dissection. Given the insights from recent studies showing the association between quality of surgery and relevant clinical outcomes, there is a great need for a formative quality assessment of LRHC. Detailed objective assessment of the LRHC is currently not performed in clinical practice nor in surgical training. Quality assessment of LRHC has great potential to improve surgical training and furthermore, implementation of a standardized technique will ultimately lead to better quality of care for patients suffering from right-sided colon cancer. The main objective of this study is to improve surgical outcomes for patient with right-sided colon cancer by a prospective sequential interventional cohort study that aims to standardize the surgical technique with subsequent controlled implementation after standardized review of the current practice in a nationwide multicenter setting. The primary endpoint is the 30-day morbidity according to the Clavien-Dindo classification system.
Small growths detected in the colon (polyps) during a colonoscopy may or may not have the potential to develop into cancer. However, since visual inspection alone cannot separate all potentially harmful polyps from harmless ones, the standard approach is to remove them all for histological lab examination, exposing patients to risk of injury and putting a significant demand on hospital resources. An accurate method of determining polyp type during endoscopy would enable the clinician to only remove potentially harmful polyps. A new endoscopic optical imaging probe (OPTIC), which analyses how light interacts with tissue, is proposed to do this. The probe is contained within a normal endoscope and uses white light and blue/violet laser light to illuminate the tissue. The reflected and fluorescent light emitted, along with normal colour pictures of the polyp surface, are measured and recorded to quantify specific characteristics of each type. Optical measurements of polyps detected in endoscopy clinics at Imperial College Healthcare NHS Trust will be analysed to determine if the signal can be used to differentiate different polyp types.
