Cancer-Related Venous Thrombosis: Residual Vein Thrombosis Improves Screening for Occult Cancer.
2007
Abstract Background. Clinical advantages of extensive screening for occult cancer in patients with idiopathic Deep Vein Thrombosis (DVT) is still debated since this approach improves early detection of cancer but not cancer-related mortality. Recently, we have demonstrated that patients with Residual Vein Thrombosis (RVT), 3 months after DVT, have a high risk for cancer in the subsequent 2 years (Siragusa S et al. Blood2005;106(11):OC262). At the present it is unknown whether RVT assessment may be used to select patients, with idiopathic DVT, who require screening for occult cancer. Objective of the study. We conducted a prospective study evaluating whether a RVT-based screening for cancer …
Prospective comparison of cardiopulmonary events during minilaparoscopy and colonoscopy under conscious sedation.
2005
BACKGROUND AND STUDY AIMS Cardiorespiratory parameters were examined throughout diagnostic minilaparoscopy procedures. The same parameters were analyzed during colonoscopy, and the data were compared. PATIENTS AND METHODS Sixty-five consecutive unselected patients undergoing minilaparoscopy (group 1: ASA I, n = 34; group 2: ASA II/III, n = 31) and 61 consecutive unselected patients undergoing colonoscopy (group 3: ASA I, n = 31; group 4: ASA II/III, n = 30) were included. Oxygen saturation (Sao (2)), heart rate (HR) and mean arterial pressure (RRm) were measured continuously, and 12-lead electrocardiography (ECG) recordings were made at specific times during each procedure. RESULTS Minor di…
Endomicroscopy of Colon Pathology
2007
Colorectal cancer is still one of the leading causes of cancer-related death in the Western world. Screening colonoscopy is widely accepted as the gold standard for early diagnosis of cancer. The prognosis for patients with colonic neoplasms is strictly dependent on the depth of infiltration and therefore depends on early detection of pre-invasive and neoplastic changes. Early detection makes it possible to cure the patient by means of immediate endoscopic resection.
Colonoscopic surveillance in inflammatory bowel disease: state of the art reduction of biopsies.
2011
Longstanding colitis in inflammatory bowel disease (IBD) is associated with an increased risk for intraepithelial neoplasia (IN). White light endoscopy (WLE) with 40–50 random biopsies has been promoted for surveillance but may miss a significant proportion of lesions. In addition, the yield of random biopsies to detect IN is low, and random biopsies are expensive, labor-intensive and distract from scrutinizing the colon. Chromoendoscopy with targeted biopsies has proven its superiority over WLE in multiple randomized trials. It has been incorporated into many national and international guidelines. Virtual chromoendoscopy techniques carry the potential to provide contrast enhancement withou…
Collagenous colitis: new diagnostic possibilities with endomicroscopy
2006
Collagenous colitis is a kind of microscopic colitis. It is characterized by chronic watery diarrhea and abdominal pain. The etiology is still unknown. So far, for the diagnose a histological evaluation was necessary with the presence of thickened subepithelial collagneous bands in the lamina propria. A new developed endoscope with a confocal laser allows analysing cellular and subcellular details of the mucosal layer at high resolution in vivo. In this case report we describe for the first time to diagnose collagenous colitis during ongoing colonoscopy by using this confocal endomicroscopy. In a 67 year old female patient with typical symptoms the characteristic histological changes could …
TRATTAMENTO ENDOSCOPICO DEI POLIPI DEL COLON-RETTO IN UN AMBULATORIO DI ENDOSCOPIA DIGESTIVA:NOSTRA ESPERIENZA
2004
The aim of this report was to evaluate the effectiveness of the endoscopic treatment of colonic polyps to allow secondary prophylaxis in order to prevent the onset of cancer arising from adenomas. From October 2002 to January 2004 we performed 487 colonoscopies on a patient group with the following indications: screening prior to kidney transplant; screening for colorectal cancer (patients positive at faecal occult blood testing); follow-up of patients who had undergone colonic resections for colorectal cancer; patients with other diseases. Colorectal polyps were diagnosed in 15 males and 15 females, with a mean age of 63 years. All the neoplasms were resected during colonoscopy and specime…
Impact of screening programme using the faecal immunochemical test on stage of colorectal cancer: Results from the IMPATTO study
2019
To evaluate the impact of faecal immunochemical test (FIT) screening on stage distribution at diagnosis, and to estimate relative incidence rates by stage in screened at first and subsequent rounds vs. unscreened. We included all incident cases occurring in 2000-2008 in 50- to 71-year-olds residing in areas with an FIT-screening programme. Multinomial logistic models were computed to estimate the relative risk ratio (RRR) of stages I and IV, compared to stage II + III, adjusting for age, sex, geographical area, and incidence year. Proportions were then used to estimate incidence rate ratios (IRR) by stage for screened subjects at the first and at subsequent rounds vs. unscreened subjects, a…
Are the recommendations of the French consensus conference on the management of colon cancer followed up?
2006
The aim of this study was to determine how the guidelines published after this conference have spread. Pretherapeutic evaluation and treatment were assessed for all colon cancers diagnosed in a well-defined French population in 2000. Patients were classified either as managed according to the recommendations, or as undermanaged or overmanaged. Outside the emergency context, pretherapeutic work-up was classified as in conformity with the consensus in 48.0% of the cases, as undervalued in 21.9% and as overvalued in 30.1%. The resection rate at 90% was not far from the optimum. Pathological data allowed us to classify nearly all cases according to the tumour node metastasis classification; how…
Clinicopathological profile of gastrointestinal tuberculosis: a multinational ID-IRI study
2020
Data are relatively scarce on gastro-intestinal tuberculosis (GITB). Most studies are old and from single centers, or did not include immunosuppressed patients. Thus, we aimed to determine the clinical, radiological, and laboratory profiles of GITB. We included adults with proven GITB treated between 2000 and 2018. Patients were enrolled from 21 referral centers in 8 countries (Belgium, Egypt, France, Italy, Kazakhstan, Saudi Arabia, UK, and Turkey). One hundred four patients were included. Terminal ileum (n = 46, 44.2%), small intestines except terminal ileum (n = 36, 34.6%), colon (n = 29, 27.8%), stomach (n = 6, 5.7%), and perianal (one patient) were the sites of GITB. One-third of all p…
Blue-light imaging compared with high-definition white light for real-time histology prediction of colorectal polyps less than 1 centimeter: a prospe…
2019
Blue-light imaging (BLI) is a new chromoendoscopy technique, potentially useful for differentiating neoplastic from nonneoplastic lesions. The present study was aimed at comparing BLI with high-definition white light (HDWL) in the real-time histology prediction of colon polyps 10 mm.Consecutive outpatients undergoing colonoscopy with the ELUXEO 7000 endoscopy platform and 760 series video colonoscopes (Fujifilm Co, Tokyo, Japan) who had at least 1 polyp 10 mm were randomized to BLI or HDWL for polyp characterization. The accuracy of high-confidence real-time histology prediction (adenoma vs not adenoma) by either BLI or HDWL for polyps 10 mm (primary end-point) and diminutive (≤5 mm) polyps…
