Active clinical trials for "Colonic Neoplasms"

A randomized controlled clinical trial to compare the outcomes of SMA- and SMV- orientated laparoscopic right hemicoloectomy for right colon cancer with a medial-to-lateral approach

61 subjects (male or female) between the ages of 45 and 75 will undergo colonoscopy. The primary outcome is Cecal Intubation

Colonoscopy is the standard of care for the detection of colorectal polyps and adenoma, and colorectal cancer detection. Despite a meticulous evaluation of the colonic mucosa during colonoscopy, a substantial number of colorectal polyps might be missed and colorectal cancer might not be prevented. Previous studies described a 12-28% of miss-rate for all polyps, a 31% for hyperplastic polyps and 6-27% for adenomas, with a higher miss rate noted for smaller polyps. The lesion missing rate depends on several factors, such as the location on difficult areas to be evaluated with conventional colonoscopes (the proximal side of the ileocecal valve, haustral folds, flexures or rectal valves), a flat shape, an inadequate bowel preparation and inadequate endoscopy technique, a time-limited colonoscope withdrawal. If the standard 140º angle of view colonoscope is used approximately 13% of the colonic surface is unevaluated. The incorporation of colonoscopes with a 170-degree wide angled could improve adenoma detection rate. The introduction of high definition (HD) colonoscopes and visual image enhancement technologies, such as narrow band imaging (NBI, Olympus America, Center Valley, PA), I-SCAN™ (Pentax Medical, Montvale, NJ) and Fuji Intelligent Chromo-Endoscopy (FICE™, Fujinon Endoscopy, Wayne, NJ) have improved the lesion characterization; however, several studies have failed to prove an increase in the adenoma detection rates. The Third Eye Retroscope (Avantis Medical Systems, Sunnyvale, CA) is a disposable retrograde viewing device advanced through the accessory channel of a standard colonoscope. It allows retrograde viewing behind colonic folds and flexures simultaneously with the forward view of the colon. Although it shows an increase in the adenoma detection rate by 11%-25%, it has many disadvantages. First, it requires a separate processor and the device is disposable, increasing the cost of the procedure. Second, it occupies the working channel of the colonoscope, limiting the ability to suction. Third, if a polyp is detected, the viewing device has to be removed in order to perform the polypectomy. Fourth, the optic is not high definition and finally, the endoscopist has to get used to visualizing and processing two simultaneous video streams from the colonoscopy and from the retroscope device.

Cancer Colon is one of the major public health problems worldwide. Complete eradication of the tumor with no recurrence or residual masses is a challenge which faces all the surgeons and medical staff all over the world. A lot of techniques were used to ensure 100 % eradication of the tumor and to cure the patients from cancer. Total Mesocolic Excision with Central Vessel Ligation is one of the recent techniques used for colon cancer surgeries. Here in the research the investigators answer the question of how this technique is superior and more beneficial in complete eradication of the tumor than the conventional surgery for colon cancer

The objective of this study is the evaluation of different imaging methods for the optimal preoperative staging of colon cancer patients. Imaging findings will be compared with the histopathologic results of the specimen following surgical resection.

This is a randomized, controlled, "non-inferiority" trial to determine the non-difference in post-operative complications rate in laparoscopic right colectomy with intracorporeal or extracorporeal anastomosis formation.

This controlled-randomized trial compares the artificial intelligence Genius® system assisted (Genius+) to standard (Genius-) colonoscopy. The aim of this study was to evaluate the impact of Genius® system on ADR in routine colonoscopy. The secondary aims will be the impact of Genius® system on polyp detection rate (PDR), serrated polyp detection rate (SPDR), advanced neoplasia detection rate (ANDR), mean number of polyps (MNP), polyp type and localization, and operator type (according to basal ADR).

A randomised back to back study comparing cap and Endocuff to detect adenomas during colonoscopy

A randomized controlled clinical trial to compare the short and long outcomes of Neoadjuvant chemotherapy with postoperative chemotherapy in patients with resectable locally advanced colon cancer

The investigators propose to evaluate Guardant Health's commercially available colorectal cancer screening assay(Guardant SHIELD) in individuals who are not up to date with CRC screening.
