Filter by:Intra-operative colonoscopy (inserting a flexible endoscope with a camera at its tip through the anus and up into the rectum and colon) is most often indicated to locate or verify the location of small cancer, polyp, bleeding site, or simply to inspect the bowel after the two ends have been rejoined together. Usually colonoscopy utilizes ambient air to expand and inflate the colon and, as a result, leaves the colon bloated or distended until the gas is either expelled or absorbed. This endoscopy related bowel distension is problematic in the setting of both traditional open (big incision) colorectal surgery and after minimally invasive (laparoscopic assisted) procedures. In the case of the former, it may prove difficult to close a traditional laparotomy incision if the bowel is distended and may hinder respiration with the abdomen closed. In the setting of a laparoscopic procedure, the bowel distension limits the working space available to the surgeon. Since the laparoscopic domain is limited, a distended colon following intra-operative colonoscopy can prevent the minimally invasive completion of a case (meaning that a conversion to traditional "open" methods would be necessary) that otherwise was going well with good prospects of laparoscopic completion. Colonic distension also causes abdominal pain and lengthens the recovery time from the procedure. The investigators believe that the use of CO2 during intra-operative colonoscopy or sigmoidoscopy (exam of only the last 2 to 2 ½ feet of the colon) will not cause long lasting bloating or distension of the colon as opposed to air. Carbon dioxide is absorbed 250 times faster than ambient air and may decrease after procedure colonic distension. This prospective, randomized study will compare the two gases in terms of colonic distension. Patients undergoing open or minimally invasive colorectal resection will be randomized to undergo intra-operative colonoscopy using one of the two gases. Direct measurements of colon diameter will be taken at specific time intervals after the colonoscopy.
The purpose of this study is to evaluate if the InSpectra StO2 Monitor can safely guide the amount of fluid needed during colorectal surgery. The study hypothesis is that intraoperative fluid limitation can be safely accomplished when guided by StO2 monitoring, and that this fluid restriction regimen will result in a reduction in postoperative morbidity when compared to standard monitoring and fluid therapy.
The purpose of this study is to determine whether the gentamicin-collagen sponge is safe and effective for preventing surgical wound infections in patients undergoing colorectal surgery.
Surgical site infections are associated with high morbidity and cost Hypothesis: Extended intraoperative hygiene measures decrease surgical site infections in general surgery compared to standard hygiene measures.
The purpose of this study is to determine whether ERAS is safe and can decrease surgical stress, increase functional recovery and reduce complication rate in colorectal surgery.
The purpose of this study is to assess if follow-up telephone calls after colorectal surgery affects a patient's satisfaction, the outcome of their surgery, and their quality of life. In addition, readmissions, complications and emergency room visits can be tracked via these telephone calls, ensuring optimal communication between patients and the surgical office.
Research Populations: Male patients scheduled for laparoscopic colorectal surgery Study Method: Questionnaire and function tests Hypothesis: A laparoscopic nerve-sparing operation is not inferior to reported open surgery in preserving urinary and sexual function.
The purpose of this study is to comparing effects of intravenously (IV) administered lidocaine to effects of epidurally (ED) administered lidocaine in patients undergoing elective colorectal surgery
To determine the optimal prophylactic antibiotics administration method in elective colorectal surgery
Most patients find that recovering from surgery is difficult particularly after abdominal surgery for cancer or other intestinal disorders. The surgical stress, healing process and concerns if further treatments are required suggest that the post-operative period may not be the best time to get people to exercise to rehabilitate lost functions. Prehabilitation is the process of enhancing functional capacity of the individual to enable him or her to withstand an incoming stressor, such as surgery, and this study aims to evaluate the effectiveness of prehabilitation for colorectal surgery. Two groups will be formed by a random process and the prehabilitation group will use an exercise cycle and weights to build endurance and strength for a 3-week period prior to surgery. The other group will receive training about exercises that will help them move better after surgery. People who are malnourished prior to surgery will receive nutritional supplements. The results of this trial will be used to inform practitioners and patients alike of the benefits (or risks if any) of exercise in preparing for surgery.
