Filter by:Patients undergoing elective surgery for left-sided colon resection are asked to participate in this study: Every patient undergoes two types of examinations (endoscopy, CT scan) on day 3, 4 or 5 postoperatively. These two procedures are subject to investigation in terms of their accuracy (sensitivity, specificity) in detection of anastomotic leaks. The patients are followed up until day 42 postoperatively. There are no other specific tests or examinations within the study. Information and informed consent are obtained preoperatively.
The aim of this study is to demonstrate the efficacy of the hydrocolonic lavage method in order to prepare the colon prior to performing a colonoscopy, by comparison the hydrotherapy to standard preparation solution. Hypothesis: Colon cleansing by hydrotherapy is as good as colon cleansing by standard preparation solution.
Up to now, many studies has showed that compared with air insufflation colonoscopy, water-related colonoscopy could shorten the cecal intubation time and relieve the pain of the patients,especially for training the beginners,the investigators conduct this study to preform the "air assisted" water injection colonoscopy in experienced endoscopists.
Water injection colonoscopy has been a generally accepted method in training the beginners of colonoscopy for its low pain and less cecal intubation time, we would conduct this study to investigate more advantages of this method and make most use of it for beginners' training.
Based on the astonishing high response rate in metastatic colorectal cancer in weekly high dose 5-FU and leucovorin, we will conduct a clinical trial to clarify the activity of this regimen in the adjuvant setting. The regimen of 5-FU and high dose leucovorin administered as the schedule of INT-0089 will be chosen as the controlled arm which was proven as effective as standard 5-FU plus levamisole regimen with short duration of treatment.21 In this study, continuous infusion of 5-FU (HDFL, Arm B) and bolus injection of 5-FU (Arm A) will be administered to the high risk colon cancer(N2 disease) patients. The role of TS level and inhibition of TS as a predictor of adjuvant chemotherapy with 5-FU based treatment will be clearly defined prospectively.
