BACKGROUND AND STUDY AIMS Adenoma miss rate during colonoscopy has become a widely acknowledged proxy measure for post-colonoscopy colorectal cancer. Among other reasons, this can happen because of inadequate visualization of the proximal aspects of colonic folds and flexures. EndoRings (EndoAid Ltd., Caesarea, Israel) is a silicone-rubber device that is fitted onto the distal end of the colono...

We hypothesized that perceived risk of colorectal cancer (CRC) and CRC worry would be the main predictors of surveillance behavior in patients undergoing colonoscopy. We therefore assessed factors predicting colonoscopy use for re-examination one year after colonoscopy. Patients who had undergone colonoscopy and were scheduled for re-examination one year later were recruited. Patients were admi...

colonoscopy overview — a colonoscopy is an exam of the lower part of the gastrointestinal tract, which is called the colon or large intestine (bowel). colonoscopy is a safe procedure that provides information other tests may not be able to give. colonoscopy is performed by inserting a device called a colonoscope into the anus and advanced through the entire colon. the procedure generally takes ...

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...

although complicated acute appendicitis is occasionally observed in general practice, the diagnosis of appendiceal abscess by colonoscopy is unusual. we report a case of appendiceal abscess with spontaneous drainage into the lumen of colon diagnosed during colonoscopy and resolved by the time of surgery.

BACKGROUND AND OBJECTIVES Primary care physicians initiate colorectal cencer (CRC) screening and manage health care issues that present from these procedures. Quality of colonoscopy services can be determined by a set of indicators. The purpose of this study was to identify the quality of colonoscopy services provided for patients of family physicians in the Iowa Research Network (IRENE). Quali...

PURPOSE Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that di...

abstract background: the combination of propofol-fentanyl for sedation during colonoscopy is characterized by the frequent incidence of side effects. etomidate-fentanyl provides fewer hemodynamic and respiratory complications. the aim of our study was to compare the safety and efficacy of propofol-fentanyl and etomidate-fentanyl for conscious sedation in elective colonoscopy. methods: this doub...
