aim : the aim of this study was to report the anatomical location and histologic type of colorectal polyps in a large series of iranian patients that attended for colonoscopy. background : polyps that develop through the adenoma-carcinoma pathway are considered neoplastic and may eventually progress to invasive carcinomas. in addition polyps can develop with no neoplastic potential. these neopl...

Background: Colonoscopy is a safe and routinely-performed diagnostic and screening procedure for different colorectal diseases. The diagnostic and screening colonoscopy for is different for colon diseases. In order for colonoscopy, colon cleansing is required to prepare a detailed view into the intestinal lumen. Aim: This is a case report study of a patient with multiple pyogenic liver abscesse...

BACKGROUND The appropriate interval between negative colonoscopy screenings is uncertain, but the numbers of advanced neoplasms 10 years after a negative result are generally low. We aimed to evaluate the cost-effectiveness of colorectal neoplasm screening and management based on repeat screening colonoscopy every 10 years or single colonoscopy, compared with no screening in the general populat...

BACKGROUND Little is known about how colorectal cancer screening test preferences operate together with test access and navigation to influence screening adherence in primary care. METHODS We analyzed data from a randomized trial of 945 primary care patients to assess the independent effects of screening test preference for fecal immunochemical test (FIT) or colonoscopy, mailed access to FIT ...

BACKGROUND AND STUDY AIMS  Some guidelines recommend a minimum standard of 90 % cecal intubation rate (CIR) in routine clinics and 95 % in screening colonoscopy, while others have not made this distinction - both with limited evidence to support either view. This study questions the rationale for making such differentiation. PATIENTS AND METHODS  We assessed cecum intubation rates amongst col...

Colonoscopy is currently regarded as the gold standard and preferred method of screening for colorectal cancer (CRC). However, the benefit of colonoscopy screening may be blunted by low participation rates in population-based screening programs. Harmful effects of population-based colonoscopy screening may include complications induced by colonoscopy itself and by sedation, psychosocial distres...

Background Adherence to colonoscopy recommendations can reduce colorectal cancer (CRC) morbidity and mortality. However, little is known about the use of colonoscopy among persons at risk for Lynch syndrome prior to clinical genetic testing (CGT) and how notification of mutation carrier status affects screening behaviors. The goal of this study was to evaluate colonoscopy use and attitudes towa...

BACKGROUND & AIMS Screening endoscopy reduces colorectal cancer (CRC) incidence but the time course and magnitude of effects beyond 10 years after screening are unknown. We aimed to estimate the expected time course and magnitude of long-term impact of screening endoscopy on CRC incidence. METHODS We used Markov models based on the natural history of the disease along with data from the Germa...

The costs of computed tomographic colonography (CTC) are not yet established for screening use. In our study, we estimated the threshold costs for which CTC screening would be a cost-effective alternative to colonoscopy for colorectal cancer (CRC) screening in the general population. We used the MISCAN-colon microsimulation model to estimate the costs and life-years gained of screening persons ...

BACKGROUND Inadequate bowel preparation during screening colonoscopy necessitates repeating colonoscopy. Studies suggest inadequate bowel preparation rates of 20-60%. This increases the cost of colonoscopy for our society. AIM The aim of this study is to determine the impact of inadequate bowel preparation rate on the cost effectiveness of colonoscopy compared to other screening strategies fo...
