Filter by:The purpose of this retrospective study was to evaluate the incidence of SSI after colorectal surgery under the general anesthesia by different general anesthetic technique: inhalation versus total intravenous anesthesia.
This study will evaluate the addition of a local anaesthetic infusion into the abdomen to patient controlled analgesia in the management of postoperative pain and recovery after bowel surgery. Half of the patients will have an infusion of a local anaesthetic called ropivacaine and half will have an infusion of placebo in addition to their normal pain relief.
This study evaluates effectiveness of mailed invitations for colorectal cancer screening among screen-eligible Ontarians who are due for screening. The study will evaluate the effectiveness of mailed invitations in general (compared to no invitation) but will also determine if new invitation letters (2 letters for male, 1 letter for females) are more effective than current invitation letters used by the ColonCancerCheck program.
The purpose of this study is to find out if giving a medicine called furosemide, which is a diuretic or water pill, after colon surgery will safely shorten the patient's length of hospital stay.
Despite of technological advances in surgery, incisional hernia and bowel obstruction remain frequent surgical complications. To date, the relationship between these two types of surgery and the occurrence of incisional hernia remains unclear. This is an observational study to evaluate outcomes of incisional hernia with respect to the incision site and adhesion-related bowel obstruction after open and laparoscopic colorectal surgery.
Surgery in persons of older AGE (SAGE) is an observational study of patients aged 60 years and older undergoing major colorectal surgery. That is to say we are looking at how older patients recovery following surgery, and that patients who volunteer to take part will absolutely not have any changes made to patients planned treatment or surgery. Patients (identified by their Consultant) will be asked if they would like to participate in the study, agreeing to undertake an additional questionnaire, blood test, provide a urine specimen and several basic physical tests during the pre-assessment visit taking an additional 30-45 minutes. This will not affect their treatment in any way. Participation is voluntary. At the time of the pre-assessment process the patient will then be approached by a researcher, who will explain the study in more detail and obtain written consent. The questionnaire is a combination of questions, which have been used in other similar studies and may be used to identify people who are fitter than others to undergo surgery. These questions are not too dissimilar to those that may be asked during the pre-assessment process. In fact some hospitals use some of these questions (but not usually all) routinely during a hospital admission process. Several basic physical tests will be performed: hand grip strength test and some basic walking and chair rising tests. These will be supervised by the trained researcher to ensure they are carried out safely. A small blood sample (20ml) will be obtained, ideally at the same time as blood is taken for the standard pre-operative assessment process. We will also take urine specimens. The blood sample and urine specimens will be saved for tests later. There are several potential blood and urine tests that may be related to physical frailty/impairment and the aging process. The patient will undergo surgery as planned and be discharged from hospital. No researcher will interfere with the planned care or conduct any data collection at this point. At approximately 1. 3, 6 and 12 months following surgery the patient will be asked to complete the questionnaire either in person, by phone or mail. If reviewed in a clinic at the time of their postoperative follow-up checks, then we will repeat the basic physical tests again also. The patient's notes will be reviewed by a researcher (who is also a doctor) to see what operation was performed, the length of hospital stay, and if any problems developed. The patients GP may also be contacted if additional information is required. This study, while based on several others, is the first of its kind to see how persons recover after surgery being assessed over one year. We will recruit for 18 months across two hospitals aiming to recruit 200 patients during this time.
The purpose of this study is to determine if an intravenous lidocaine infusion (compared to placebo) intraoperatively will decrease time to return of bowel function postoperatively, decrease postoperative pain, diminish postoperative opioid requirement, minimize inflammatory markers and shorten time to discharge after colorectal surgery.
The primary objective of the present trial is to investigate, the mean operative time and to study the frequency and intensity of postoperative shoulder tip pain in patients undergoing laparoscopic surgery, i.e. cholecystectomy, colorectal surgery, hernia repair with AirSeal® compared with standard pressure CO2 insufflation systems. The primary hypothesis is that patients operated with AirSeal® have a shorter mean operative time and decreased frequency and intensity of postoperative shoulder tip pain compared with patients undergoing surgery with standard pressure CO2 insufflation systems. It is the secondary objective of the trial to evaluate immunologic and anaesthesiological aspects of laparoscopic cholecystectomy, colorectal surgery and laparoscopic hernia repair by observing the immune responses and volume of mechanical ventilation of the two groups through measuring various immunologic factors and ventilation volume/CO2 elimination volume. Surgical side effects will also be measured as secondary objective.
Fast-track (FT) surgery is a multimodal, multidisciplinary-team approach to reduce perioperative surgical stress and injury after colorectal surgery, resulting in lower morbidity and enhanced recovery. As fast-track approach could probably be the most beneficial for senior patients to reduce postoperative morbidity and better preserve independency, only scarce information is available in senior population. Therefore a randomized controlled trial is initiated in our institution compare a senior dedicated fast-track approach to modern standard care after colorectal surgery.
The investigators hope to determine whether the addition of an FOBT kit and educational materials to a second mailed invitation compared to a second mailed invitation alone increases use of appropriate screening tests (FOBT for average risk or colonoscopy if increased risk) by eligible persons within 6 months of the second mailing in: (1)Non-responders to an initial mailed CRC screening invitation from their family physician and, (2)Those who responded to the initial mailed CRC screening invitation and are due for repeat screening (i.e., "recall" patients). In addition, the investigators will also explore the impact of the investigators intervention in likely under-screened groups such as those living in more remote areas of the province and those with low socio-economic status as well as assessing the cost-effectiveness of this strategy.
