Open Access Colonoscopy is the most effective and popular method for the screening, prevention, and diagnosis of colorectal cancer worldwide. However, there have been concerns on the ability of colonoscopy to detect adenoma. Colonoscopic examination is limited in this regard even if lesions are not missed because of variables such as the endoscopist' s skill, experience, and the degree of bowel...
This retrospective study aimed to clarify the clinical characteristics of advanced colorectal neoplasms after colonoscopy, likely to have been missed on the previous colonoscopy. We reviewed a total of 5,768 consecutive colonoscopies performed from April 2010 to September 2013 in 4,841 patients, and analyzed advanced colorectal neoplasms after colonoscopy, particularly focusing on their morphol...
Screening Colonoscopy A screening colonoscopy is done to check for cancer and inflammatory diseases like ulcerative colitis. Most colorectal cancers (CRC) start as non-cancerous polyps (tiny, fast growing cells that may become cancer). Removing polyps or finding cancer at an early stage can increase your chances for a full recovery.2 During the colonoscopy, polyps can be removed with tiny instr...
BACKGROUND In patients with incomplete colonoscopy, cecal intubation is sometimes unsuccessful due to a redundant or tortuous colon. Repeat colonoscopy may be successful with the use of alternate endoscopes or careful attention to technique but limited outcomes data is available. The aim of this study was to describe the technique, success rate and outcomes of consecutive patients referred for ...
BACKGROUND The clinical benefit of early colonoscopy within 24 h of arrival in patients with severe acute lower gastrointestinal bleeding (ALGIB) remains controversial. This trial will compare early colonoscopy (performed within 24 h) versus elective colonoscopy (performed between 24 and 96 h) to examine the identification rate of stigmata of recent hemorrhage (SRH) in ALGIB patients. We hypoth...
OBJECTIVE The clinical significance of flat lesions in colorectal cancer screening remains uncertain. The purpose of this study was to investigate the frequency, histology, and virtual colonoscopy detection of flat lesions in an asymptomatic screening population. SUBJECTS AND METHODS The morphology of all detected polyps was prospectively recorded as flat or polypoid (sessile or pedunculated)...
introduction: pain during colonoscopy, especially in children, including the challenges faced by the medical team. the aim of study was investigation the analgesic effect supermint oil (peppermint oil) on pain in children during colonoscopy. methods and materials: in this clinical trial study, 101 children (7-14 years old) candidate colonoscopy were randomly divided into two groups, respectivel...
Colonoscopy is effective in reducing the morbidity and mortality associated with colorectal cancer (CRC). Interval cancers or post-colonoscopy CRCs, are cancers detected within the surveillance interval, or between 6-36 months after a clearing colonoscopy. The incidence of interval cancers is 3.4%-9.2% of all detected CRCs, as reported in population-based studies. Colonoscopy is a technically d...
Colonoscopy is the cornerstone of colorectal cancer screening programs. There is significant variability in the quality of colonoscopy between endoscopists. Colonoscopy quality assessment tracks various metrics to improve the effectiveness of colonoscopy, aiming at reducing the incidence and mortality from colorectal cancer. Adenoma detection rate is the prime metric, because it is associated w...
