Colonoscopy, Tumors, and Inflammatory Bowel Disease - New Diagnostic Methods

2006

Accurate detection of premalignant lesions and early cancers in the colon is essential for curative endoscopic or surgical therapy, since the prognosis for the affected patients is closely related to the size and stage of the neoplastic lesion. Total colonoscopy is the accepted gold standard for screening and surveillance of colorectal cancer. This review summarizes recently published diagnostic developments and key findings in the areas of colonoscopy, colonic tumors, and inflammatory bowel diseases. Relevant findings have been reported for chromo-endoscopy in the diagnosis of colitis-associated neoplasia, as well as flat and depressed adenomas. Real-time Doppler capabilities have now been…

Endoscopic Management for Patients with Serrated Polyposis Syndrome is Feasible and Effective:

2014

Background and Study Aims: Serrated polyposis syndrome is a rare condition in which multiple serrated lesions develop all over the colon, which is thought to be associated with an increased risk for the development of cancer. The aim of this study was to investigate the feasibility of endoscopic treatment and standardised surveillance in patients with this increasingly recognised syndrome. Methods: From September 2010 to November 2013, consecutive patients were included in a prospective study. All patients underwent chromoendoscopy at first presentation and during surveillance. Follow-up examinations were carried out at 3 month intervals until complete clearance was achieved. Afterwards, pa…

Colorectal Polyps

2008

Publisher Summary Colorectal cancer (CRC) remains the second leading cause of cancer death for both women and men with more than 130,000 newly diagnosed cases and 50,000 deaths each year in the United States alone. Most colon cancers develop from nonmalignant colonic adenomas or polyps over a comparatively long time period ranging between 24 and 60 months. Reflecting this adenomatous pathogenesis of most colorectal cancers, polyp screening with subsequent polypectomy is used to constitute an effective approach for decreasing the incidence of this malignant tumor. Thus, colorectal screening for polyps may be considered one of the most promising preventive measures in medicine. Most available…

El uso precoz de la tomografía computarizada en el manejo de la diverticulitis aguda

2007

Objetivo: valorar el uso precoz de la tomografía computarizada (TC) para el diagnóstico, estadificación y manejo de la diverticulitis aguda. Material y métodos: realizamos un estudio prospectivo de 102 pacientes con el diagnóstico clínico de diverticulitis aguda de colon izquierdo. La diverticulitis aguda fue inicialmente dividida en tres estadios. Los pacientes fueron reestadiados en los estadios I, IIa, IIb y III de acuerdo a los hallazgos encontrados en la TC. El diagnóstico se confirmó después intraoperatoriamente, por colonoscopia o estudio con bario. Resultados: fueron incluidos 102 pacientes (52 mujeres y 50 hombres) con una edad media de 59,4 (DS ± 14,96). En 84 (82,35%) paci…

Confocal Laser Endomicroscopy and Chromoendoscopy - A New Option of Surveillance in Patients with Ureterosigmoidostomy or Rectosigmoid Pouch

2010

Purpose In patients with bladder exstrophy-epispadias-complex (BEEC) or in selected patients with bladder loss for other reasons, ureterosigmoidostomy (USIG) & rectosigmoid pouch (Mainz Pouch (MZP) II) has been used at our institution. This diversion carries a lifelong risk for secondary malignancies. Therefore annual colonoscopy is recommended. Identification of potentially malignant structures can be challenging, and biopsies are taken in doubt, with the risk of injuring the ureterocolic implantation site. Using confocal laser endomicroscopy (CLE) and chromoendoscopy, the uretero-intestinal anastomosis is better visualized compared to conventional colonoscopy, and target biopsies could be…

Use of BICAP in a case of colon angiodysplasia

1991

This paper reports on a case of colonic bleeding from an angiodysplastic lesion of the ascending colon in a 71-year-old diabetic woman, resulting in severe anemia in the patient, who was treated using the BICAP electrocoagulation system. The present report includes a description of this technique, which involves the use of a 7-F hemostatic probe connected to a 25-W BICAP source.

Conservative Treatment of Splenic Haematoma After Colonoscopy: A Case Report

2020

Colonoscopy is a routine procedure performed worldwide, nevertheless, a small risk of splenic injury, often under-estimated, is still present. As a matter of fact, the diagnosis may be delayed, leading to a rising risk of morbidity and mortality. This paper describes a case of conservative treatment of colonoscopy-associated splenic injury. A 57-year-old woman presented with worsening pain in the upper left abdominal quadrant; she had radiation therapy to the ipsilateral subscapular region, and a diagnostic colonoscopy 18 hours earlier. The computed tomography (CT) scan revealed splenic laceration without signs of hemoperitoneum. Because of the hemodynamic stability of the patient, successf…

Anti-TNF-Antikörper zur Therapie von entzündlichen Darmstenosen bei Morbus Crohn

2003

Stenoses are a frequent complication in patients with Crohn's disease and represent a major diagnostic and therapeutic challenge. The proper assessment of the nature of a stenosis as inflammatory or fibrotic is critical for appropriate treatment, since symptomatic fibrotic stenoses require surgical resection. Standard diagnostic procedures to assess the nature of a stenosis include endoscopy, conventional contrast radiography and magnetic resonance tomography. Recent data suggest, that the positron-emission-tomography possesses a high sensitivity and specificity to confirm inflammatory activity in the bowel. The recombinant monoclonal anti-TNF-antibody Infliximab (Remicade) has been approve…
