Background and study aims National societies recommend colorectal cancer (CRC) screening 10 years after a normal (“negative”) colonoscopy in low-risk individuals. We studied the impact of a 10-year repeat colonoscopy on the risk of early incident CRC. Patients and methods We used health administrative data from Ontario, Canada, to conduct a population-based retrospective cohort study in 50–74-y...

Background: There is convincing evidence from epidemiological studies that meat consumption increases colorectal cancer (CRC) risk. However, assessment of any association with a positive fecal immunochemical test (FIT) in CRC screening has been limited. If a link could be shown this might be helpful for establishing a risk group for colonoscopy. Objective: This study aimed to assess any associa...

A 22-year-old male patient presented with a 3-month history of persistent, colicky, lower abdominal pain. He was referred for colonoscopy. Total colonoscopy showed multiple small-to-medium sized pale pink, nonulcerated, polypoid lesions in the distal part of the rectum, occupying most of the circumference (▶Fig. 1). The patient’s medical history was not significant. After discussing his sexual ...

Colorectal cancer is one of the most common malignancies in Europe and North America. Colonoscopy done every 10 years beginning at age 50 is the preferred method of screening. In Poland and some other countries examinations are offered to subjects free of charge. However, as well as direct medical costs there are direct non-medical costs, which include the cost of transportation and costs relat...

BACKGROUND Colorectal cancer is the most common cancer in Germany. Screening colonoscopies have been offered as a primary screening tool in Germany since the end of 2002. OBJECTIVE To estimate the numbers of clinically manifest colorectal cancers prevented by detection and removal of advanced adenomas in the initial 6 years of the program. DESIGN Markov model with single-year transitions. ...

conclusions iv bolus injection of propofol-ketamine can lead to more patients’ satisfaction than the other protocols during colonoscopy. results mean satisfaction scores in the group pk were significantly higher than the group pf (p = 0.005) while the level of sedation during the procedure was similar (p = 0.17). hemodynamic parameters and spo2 values were not significantly different (p > 0.05)...

conclusions midazolam/meperidine and propofol sedation for colonoscopy have similar cardiopulmonary safety profiles and patient satisfaction levels. midazolam/meperidine can be preferred to propofol sedation due to a shorter hospital length of stay and better analgesic activity. the patient satisfaction rates were not significantly different between the groups; however, patients in the propofol...

AIM: to evaluate the impact of dietary compliance in bowel cleansing for colonoscopy on quality procedure. PATIENTS AND METHODS: one thousand patients who scheduled diagnostic were included prospective observation study. The preparation was assessed using Boston scale. Neoplasms detected and endoscopically evaluated. optical verification tumors used calculate indicators identified adenomas poly...

background: although some patients can tolerate colonoscopy procedure using fentanyl/ midazolam without any sedation and analgesic requirements but some patients may require additional sedation with benzodiazepines. we performed the present study to compare the effect of paracetamol/midazolam with fentanyl/ midazolam. methods: in a clinical trial, 96 patients aged 18 to 75 years old, who were c...

CONTEXT Acromegalic patients have better chances to develop colorectal polyps and cancer and, considered a high-risk group, need to undergo frequent screening examinations. Moreover, in acromegalia, the increased bowel length and the intestinal loop complexity can lead to higher levels of technical difficulties and increase the risks of complications at conventional colonoscopy. Computed tomogr...
