“…More important than affecting the speed or completion of colonoscopy, poor bowel preparation increases the risk of missed adenomas and CRC. Several studies have also found that the frequency of adenomas detection is greater with high‐quality bowel preparation compared to fair or poor bowel preparation . Flat and depressed lesions carry a higher risk of advanced neoplasm and are thought to progress more swiftly to CRC, and concerningly one study has found the detection of these lesions is significantly less in patients with inadequate bowel preparation …”

The year 1969 marked a revolution in the diagnosis of colorectal cancer (CRC). It is when Dr Wolff developed the colonoscope and quickly realized its potential in both diagnosis and treatment of colonic neoplasms. Over the past 50 years there has been exponential increase in utilization of colonoscopy with over 1 million colonoscopies performed annually throughout Australasia. Endoscopic removal of pre‐malignant lesions has been proven to reduce the incidence and mortality of colorectal. Although timing and frequency of surveillance colonoscopy plays a crucial role in risk reduction of CRC, this is dependent upon the findings of the index colonoscopy. The goal of screening colonoscopy is to detect CRC and identify and remove pre‐malignant neoplasms that risk progression to CRC. With increasing uptake of bowel screening throughout Australasia, there is increasing pressure to ensure all endoscopists and endoscopy units perform at a universal high‐quality. All too often high demand and constant delays compromise colonoscopy quality. Without clear and concise quality indicators with transparent measurement and audit, these flaws can quickly jeopardize screening goals and patient outcomes. This review aims to explore six key quality indicators and explore the evidence behind the current recommended standards. These key indicators include; rate of adequate bowel preparation, caecal intubation rate, adenoma detection rate, withdrawal time, complication rates and surveillance intervals.

“…Colonoscopies repeated at time interval longer than 3 years showed a significant high-risk adenoma detection rate. Based on these results, they suggest a surveillance interval of no more than 3 years for subjects having an index colonoscopy with suboptimal bowel preparation despite the complete initial colonoscopy [21]. Menees et al reviewed the colonoscopy reports of averagerisk individuals with a normal initial (index) endoscopy.…”

Colonoscopy represents a very important diagnostic modality for screening for colorectal cancer, because it has the ability to both detect and effectively remove pro-malignant and malignant lesions. It is recommended by almost all international and national gastroenterology and cancer societies, as an initial screening modality or, following a positive fecal occult blood test, to be performed every 10 years in individuals of average risk starting from the age of 50. However, a significant problem is the so-called post-screening (interval) polyps and cancers found some years after the index colonoscopy. In order to reduce the rate of interval cancers it is extremely necessary to optimize the quality and effectiveness of colonoscopy. Bowel preparation is of paramount importance for both accurate diagnosis and subsequent treatment of lesions found on colonoscopy. The quality of bowel preparation could be significantly improved by splitting the dose regimens, a strategy that has been shown to be superior to single-dose regimen. A good endoscopic technique and optimal withdrawal time offering adequate time for inspection, would further optimize the rate of cecal intubation and the number of lesions detected. During the last years, sophisticated devices have been introduced that would further facilitate cecal intubation. The percentage of total colonoscopies is now super-passing the level of 95 % allowing the adenoma detection rate to be greater than the suggestive level of 25 % in men and 15 % in women. This review aims to provide the reader with the current knowledge concerning indications, usefulness, limitations and future perspectives of this probably most important screening technique for colorectal cancer available today.

“…Moreover, two negative examinations for intermediate risk patients require no further follow‐ups. (Cairns et al, ) Finally, one negative examination for high‐risk patients changes the patient category to intermediate risk showed that an increased number of high‐risk adenomas were detected in colonoscopies that are performed more than three years after the initial colonoscopy (Cairns et al, ; Singhal, Virk, Momeni, Krishnaiah, & Anand, ). Currently, the most commonly used colonoscopy technique is white light optical colonoscopy.…”

Colonoscopy technologies for diagnostics and drug delivery

With a global increase of colorectal cancer, inflammatory bowel disease and other colon-related illnesses, advanced technologies are needed for imaging of the colon and localized drug delivery. Optical colonoscopy is the gold standard for imaging of the colon. However, existing colonoscopy approaches have a high adenoma misdiagnosis rate, which can be lethal for patients. This article reviews the emergence of virtual colonoscopy, dye-based chromoendoscopy, electronic chromoendoscopy and capsule endoscopy in diagnosis. Flexible spectral imaging colour enhancement, the use of second-generation capsule endoscopy and i-scan were described. Moreover, a drug delivery system using capsule endoscopy was discussed. Finally, this review includes market analyses of commercial products, clinical trials and future prospects of colonoscopy devices.
