Diagnostic colonoscopy has evolved to become the gold standard for the screening for carcinoma and other diseases of the colon. Injuries to the colon are rare and may be managed in a variety of ways. This includes observation and bowel rest or operative intervention and repair. Other organs are at risk during colonoscopy. The present report describes a patient who underwent colonoscopy for the ...

Background Stool tests can predict advanced neoplasms prior to colonoscopy. Results of immunochemical stool tests to predict findings at colonoscopy for various indications are less often reported. We compared pre-colonoscopy stool tests with findings in patients undergoing colonoscopy for different indications. Patients and methods Charts of patients undergoing elective or semi-urgent colono...

Education and competency assessment in gastrointestinal endoscopy is important. Concerning colonoscopy, it is not completely clear what the best way is to learn this procedure, what defines competency in colonoscopy, and which factors define a high-quality colonoscopy. The aim of this study was to determine the endoscopist-related factors that define a high-quality colonoscopy. A three-round De...

Splenic injury is a rare but serious complication of colonoscopy. Since the mid-1970s, 68 splenic injuries during colonoscopy including our 2 cases have been described. With the increasing use of colonoscopy, endoscopists, surgeons, and radiologists are more likely to encounter this unusual complication. Any cause of increased splenocolic adhesions, splenomegaly, or underlying splenic disease m...

BACKGROUND/AIMS Variation exists among anesthesia providers as to acceptable timing of NPO ("nothing by mouth") for elective colonoscopy procedures. There is a need to balance optimal colonic preparation, patient convenience, and scheduling efficiency with anesthesia safety concerns. We reviewed the evidence for the relationship between NPO timing and aspiration incidence and colonoscopy resche...

OBJECTIVES To evaluate the use of colonoscopy in patients aged at least 85 years. Does the ideal of an ageism free service apply? DESIGN A retrospective audit. SETTING Department of gastroenterology that carries out about 1000 colonoscopies annually in a district general hospital serving a population of about 320 000. SUBJECTS All patients aged at least 85 years who underwent colonoscopy ...

RK Colonoscopy is considered to be the gold standard of colon cancer screening. In fact, colonoscopy has been shown to reduce colon cancer mortality by approximately 50%. However, colonoscopy is not as effective on the right side of the colon as it is on the left side of the colon. Flat and serrated adenomas (precancerous conditions) are more common on the right side of the colon and harbor an ...

Colonoscopy is the current standard method for evaluating the colon. Recent surveys have shown that the proportion of individuals aged 50 years or older who have undergone colonoscopy within the last 10 years is growing and currently ranges from 6%–25% in various European countries to 62% in the United States [1, 2]. Bowel preparation for colonoscopy is a complex undertaking, involving diet mod...

We present a set of tools used to enhance the optical colonoscopy procedure in a novel manner with the aim of improving both the accuracy and efficiency of this procedure. In order to better present the colon information to the gastroenterologist performing a conventional (optical) colonoscopy, we undistort the radial distortion of the fisheye view of the colonoscope. The radial distortion is m...

BACKGROUND Water-aided methods for colonoscopy are distinguished by the timing of removal of infused water, predominantly during withdrawal (water immersion) or during insertion (water exchange). OBJECTIVE To discuss the impact of these approaches on colonoscopy pain and adenoma detection rate (ADR). DESIGN Systematic review. SETTING Randomized, controlled trial (RCT) that compared water-...
