Magnetic endoscopic imaging (MEI) allows the configuration of the endoscope shaft to be visualised during colonoscopy. In particular, it allows the operator to confidentally recognise loop formation and subsequent loop resolution which is vital for colonoscope tip advancement and thus complete visualisation of the colon. Although generally accepted as a useful aid during colonoscopy, it is not universally available either due to cost or this facility is not available or compatible with all manufactured endoscopes. The data on its utility with regards colonoscopy performance outcome measures is mixed but overall likely to be beneficial. Its main value probably relates to colonoscopy training and its value may be realised with the large expansion in workforce required with the recent introduction of bowel cancer screening. Further work in this area is required. The manufacturer suggests some minor limitations in use because of potential interference with implanted electronic device, but its safety overall is well recognised.

“…Regarding the first aim, simple methods such as water- or oil-lubricated colonoscopy [37, 38] have been shown to be useful in randomized trials, but have obviously not gained widespread acceptance. The effect of external localizers has been studied in randomized trials, with apparent benefit only with trainees involved, but not with experienced colonoscopists [39, 40]. Colonoscopes with variable stiffness functions were mostly found to be superior in terms of patient pain and ease of introduction in 4 randomized trials [41,42,43,44].…”

Colonoscopy has been established as a screening tool for colorectal cancer and precursors in some countries. Efforts to improve instrument performance as well as patient comfort, safety and compliance have led to modifications of existing endoscopes as well as to the development of new scopes with different working mechanisms, including the colon capsule. While the former have not substantially changed performance, the true value of new scopes – partially single use and/or self propelling – can not be fully assessed, since they are either still under development and/or tested only in animals and in small groups of patients or volunteers. The colon capsule holds promise but has a too complicated preparatory regimen and too low a sensitivity at the moment. Future developments and further studies will show which of these techniques may complement or even replace traditional screening colonoscopy.

“…Shah [6] has shown that even in the hands of expert endoscopists, correct identification of loop configuration occurred only 31% of the time. As the image generated is in real time, loops can be detected and straightened as soon as they form, resulting in shorter intubation time and higher completion rates [7] . Appropriate position change of the patient or a bdominal pressure can be used to correct to loop, if it's configuration is known.…”

“…This feedback gives the operator a better understanding of how loops form, how this changes the resistance of scope insertion and how to prevent and straighten these loops. Shah [7] has shown that trainees using the MR imaging colonoscope have a higher completion rate and spend less time looping the instrument. As a result we should have more proficient endoscopists in the future.…”

Advances in technology continue at a rapid pace and affect all aspects of life, including surgery. We have reviewed some of these advances and the impact they are having on the investigation and management of c o l o r e c t a l c a n c e r . M o d e r n e n d o s c o p e s , w i t h magnifying, variable stiffness and localisation capabilities are making the primary investigation of colonic cancer easier and more acceptable for patients. Imaging investigations looking at primary, metastatic and recurrent disease are shifting to digital data sets, which can be stored, reviewed remotely, potentially fused with other modalities and reconstructed as 3 dimensional (3D) images for the purposes of advanced diagnostic interpretation and computer assisted surgery. They include virtual colonoscopy, trans-rectal ultrasound, magnetic resonance imaging, positron emission tomography and radioimmunoscintigraphy. Once a colorectal carcinoma is diagnosed, the treatment options available are expanding. Colonic stents are being used to relieve large bowel obstruction, either as a palliative measure or to improve the patient's overall condition before definitive surgery. Transanal endoscopic microsurgery and minimally invasive techniques are being used with similar outcomes and a lower mortality, morbidity and hospital stay than open trans-abdominal surgery. Transanal endoscopic microsurgery allows precise excision of both benign and early malignant lesions in the mid and upper rectum. Survival of patients with i n o p e r a b l e h e p a t i c m e t a s t a s e s f o l l o w i n g radiofrequency ablation is encouraging. Robotics and telemedicine are taking surgery well into the 21 st century. Artificial neural networks are being developed to enable us to predict the outcome for individual patients. New technology has a major impact on the way we practice surgery for colorectal cancer.Subject headings colorectal neoplasms; technology; surgery; radiology
