BACKGROUND Data on the quality of colonoscopies in populations with rising colorectal cancer (CRC) incidence is scarce. We aimed to calculate the adenoma detection rates (ADR), and assess the quality of colonoscopies in an opportunistic screening colonoscopy program in Iran. METHODS All the colonoscopy and pathology reports of asymptomatic adults over age 50 who underwent screening colonoscop...
BACKGROUND Current guidelines recommend screening colonoscopy in first-degree relatives of patients with colon cancer. The aim of this state-wide study was to investigate the compliance for colonoscopic in first-degree relatives, who were younger than 60 years of age. METHODS A total of 602 patients were identified from the tumor registry of the public health insurance of Lower Saxony. A ques...
BACKGROUND Despite evidence that several colorectal cancer (CRC) screening strategies can reduce CRC mortality, screening rates remain low. This study aimed to determine whether the approach by which screening is recommended influences adherence. METHODS We used a cluster randomization design with clinic time block as the unit of randomization. Persons at average risk for development of CRC i...
Background and purpose: Colonoscopy is an invasive short-lasting procedure causes the patient's considerable pain, discomfort and anxiety. Therefore, various types of sedation and analgesia techniques have been used during the procedure. The aim of this study was to compare the quality of sedation/analgesia of propofol-fentanyl and midazolam-meperidine combinations in patients undergoing electi...
BACKGROUND There are limited colonoscopy-based cohort data concerning the effectiveness of colonoscopy in reducing colorectal cancer deaths. The aim of this study was to clarify whether colonoscopy reduces colorectal cancer mortality. METHODS A cohort of 18,816 patients who underwent colonoscopy without a diagnosis of colorectal cancer between 2001 and 2010 at high colonoscopy procedure volum...
BACKGROUND Although rates of detection of adenomatous lesions (tumors or polyps) and cecal intubation are recommended for use as quality indicators for screening colonoscopy, these measurements have not been validated, and their importance remains uncertain. METHODS We used a multivariate Cox proportional-hazards regression model to evaluate the influence of quality indicators for colonoscopy...
