Management of rectal cancer in France in a well-defined population.
2014
Objective The aim of this study was to draw a picture of diagnostic assessment and patterns of care for rectal cancer in France using population-based registries data. Methods The study included a random sample of 669 cases of rectal cancers diagnosed in 2005. Results Diagnostic assessment was performed by colonoscopy in 91.4% of the cases. An abdominal computed tomography was performed in 59.4% of the cases and chest computed tomography in 47.8%. An R0 resection was performed in 65.8% of cases and an R1/R2 resection in 16.1%. A rectal endosocography was performed in 40.4% and MRI in 10.4%. The sphincter was preserved in 73.6% of patients aged younger than 75 years of age and in 62.5% of th…

P288 Vedolizumab May Be An Effective Option For The Management Of Postoperative Recurrence Of Crohn’s Disease
2021
Abstract Background The role of Vedolizumab (VDZ) as therapeutic option for the postoperative recurrence of Crohn’s disease (CD) following ileocolonic resection is currently unknown. We aimed to assess the effectiveness of VDZ in this setting. Methods All consecutive CD patients with an available baseline colonoscopy at 6-12 months from the ileocolonic resection and treated with VDZ for the postoperative recurrence after the baseline colonoscopy were extracted from the cohort of the Sicilian Network for Inflammatory Bowel Diseases (SN-IBD). The primary outcome was endoscopic success, assessed at the first colonoscopy following initiation of VDZ. In patients with Rutgeerts score i0 or i1 at …
An unmet medical need:advances in endoscopic imaging of colorectal neoplasia
2011
Gastrointestinal cancer is a major public health problem worldwide. Detection of early neoplastic lesions in gastrointestinal tract is essential for cure, because prognosis and survival are related to the size and stage of malignant lesions. Endoscopic screening and treatment of polyps could prevent approximately 80% of colorectal cancer (CRC). However, white-light endoscopy is an imperfect technology since miss rates of up to 25% have been reported and polyps without malignant potential were treated without benefit but with additional costs and risks to the patient. There are several known "human" predictors of an inadequate colonoscopy. These include patient characteristics such as poor b…
Endoscopic mucosal resection: an evolving therapeutic strategy for non-polypoid colorectal neoplasia
2004
Endoscopic management for laterally spreading tumours of the colorectum is a safe and effective treatment and may be an alternative to surgery in selected patients Colorectal cancer develops in approximately 5–6% of the adult population and is one of the leading causes of cancer death in Europe and the USA.1,2 Screening colonoscopy is the widely accepted gold standard for early diagnosis of colorectal cancer and should be offered to patients older than 50 years.3–5 However, colonoscopy is increasingly in competition with computed tomographic virtual endoscopy.6 Therefore, it is essential to understand whether total colonoscopy rather than virtual endoscopy enables the detection of all relev…
Patient-to-patient transmission of hepatitis C virus (HCV) during colonoscopy diagnosis
2010
Abstract Background No recognized risk factors can be identified in 10-40% of hepatitis C virus (HCV)-infected patients suggesting that the modes of transmission involved could be underestimated or unidentified. Invasive diagnostic procedures, such as endoscopy, have been considered as a potential HCV transmission route; although the actual extent of transmission in endoscopy procedures remains controversial. Most reported HCV outbreaks related to nosocomial acquisition have been attributed to unsafe injection practices and use of multi-dose vials. Only a few cases of likely patient-to-patient HCV transmission via a contaminated colonoscope have been reported to date. Nosocomial HCV infecti…

Inflammatory manifestations at colonoscopy in patients with colonic diverticular disease
2010
Aliment Pharmacol Ther 2011; 33: 358–365 Summary Background Ulcerative colitis with diverticulosis (UCD), segmental colitis associated with diverticulosis (SCAD) and acute uncomplicated diverticulitis (AUD) may affect the same colonic regions, but the real incidence of these entities in clinical practice is unknown. Aim To assess the incidence and the endoscopic findings of UCD, SCAD and AUD. Methods From January 2004 to June 2009, 8525 consecutive colonoscopies were performed. Diagnosis of the diseases was based on specific endoscopic and histological (UCD and SCAD), and on endoscopic and radiological (AUD) patterns. Results Ulcerative colitis with diverticulosis was diagnosed in 25 pa…
Endomicroscopy for a reliable diagnosis of colorectal neoplasia
2010
The modern colonoscopist faces two problems: identifying all relevant lesions and then making an appropriate risk assessment of the detected lesions. The latter is crucial for determining patient outcome. A feasibility study suggests that a new endomicroscopy technology could greatly improve the detection and assessment of neoplastic colorectal lesions.
