Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide [1]. This disease may begin with non-cancerous polyps in the colon, which, if not treated in time, can develop into cancer [2]. Typically, CRC progresses through the “adenoma-carcinoma” sequence, with...
Colonoscopy is regarded as an important diagnostic and therapeutic tool for diseases of the colon. As CRC-screening and other surveillance programmes (e.g. inflammatory bowel disease, IBD) increase globally, the number of performed colonoscopies and, consequently, the need for colonoscopy increases as...
estimation, a localization system was developed that can identify the location index of each frame as well as which anatomical colon segment it belongs to. An overview of the system is shown inFig. 1. The proposed localization system starts with the detection and removal of non-informative frame...
16. The guide of claim 15, wherein each of said one or more ring members has a longitudinal slot sized and configured to receive the endoscope through said slot. 17. A colonoscope guide for use with an endoscope in a colonoscopy procedure, said colonoscope guide comprising:an elongated ...
16.8%, P = 0.908), lesion detection rate of cecum (4.9% vs. 4.7%, P = 0.613) and ascending colon (13.5% vs. 13.2%, P = 0.656) between the two groups. Conclusion TII was not necessary in routine colonoscopy, owing to the limited diagnostic value and lack of superiority...
Fig. 2. Tree diagram of the revised coding framework, showing the relationships between themes, higher order themes and superordinate themes. Themes in red (squares) represent barriers of colonoscopy, themes in yellow (hexagons) represent themes which could be either barriers or facilitators of colo...
The mechanical model of cantilever beam is force diagram is drawn and the mechanical analysis of single section in bending process is mainlv analyzed. Finally, 'Pro/E' is used to build model and simulate the process that the snake-like Loes through the colon. This paper lays foundation for ...
size and composition.The method is further adapted to reduce the particle structure of the colon content prior to the diagnostic test and / or apply to a patient who has received a limited range of pre-treatment for correction or to a patient who has not received any pretreatment.Diagramハ...
Figure 1. PRISMA flow diagram of study selection. Study and patient characteristics Study and patient characteristics are presented in Table 1. Most studies included a single endoscopist who performed all procedures. Only 2 studies described insufflation techniques, both of which reported use of air ...
A tornedo diagram demonstrated that the variables with the most influence on the results of the analysis included the prevalence of right sided lesions, the enteroscopy miss rate, and cost for the enteroscopy with or without polypectomy. Conclusions For patients with incomplete screening colonoscopy ...
