Filter by:This prospective study aims to assess the efficacy of the OviTex 1S permanent mesh in pelvic floor surgery in comparison with the current standard polypropylene mesh.
This study aims to develop a highly sensitive, specific, and cost-effective blood assay for early detection of colorectal adenomas and cancer, using advanced machine learning and state-of-the-art biological analyses.
The goal of this clinical trial is to compare two types of closure in patients with ostomies that are ready for closure. The main questions it aims to answer are: 1. Surgical site infection rates 2. Patient quality of life 3. Time to wound healing Participants will undergo either complete ostomy wound closure after washing out the wound with Prontosan, or their ostomy wound will be closed using the Pursestring method, where the wound will be left partially open and allowed to heal from the inside out. Researchers will compare these two groups' outcomes (questions to be answered) as listed above.
A short bolus infusion of fluid, called "fluid challenge" is commonly recommended for fluid treatment during longer surgery. However a prolonged increase of the blood volume is a prerequisite to recommend the technique. The purpose with the study is to examine the plasma expanding effect of three different fluid challenge strategies (acetated Ringers 4 ml/kg body weight, albumin 5% 4 ml/kg body weight or albumin 20% 1 ml/kg body weight), using hemoglobin as a dilution indicator.
Dexamethasone will be used as an adjunct to local anesthetics (bupivacaine) to prolong the duration of laparoscopically-placed transversus-abdominis plane blocks in elective colorectal resection.
Currently a multiport robotic surgery platform (Intuitive Xi) is widely available and used for colorectal surgery indications. A Single port platform (Intuitive SP) is FDA approved for Head and Neck and Urology but has not been widely used in colorectal surgery. This study seeks to evaluate the safe and effective use of the SP platform for colorectal surgery indications.
This is a study comparing major bowel surgery done via conventional keyhole (laparoscopic) surgery with robotic assisted keyhole surgery, using the Versius robotic system. Our main objective is to assess the physical strain of both types of surgery on the operating surgeon, but we will also collect data on the patient outcomes and teamwork. This results from this study will be used to guide the design of a larger scale trial in future.
To prospectively study the effect of adherence to ERAS and PBM programs on early outcomes after colorectal surgery
This is a randomized, controlled, parallel, multicenter trial to compare post-operative complications and long-term results between open and laparoscopic technique in emergency colorectal surgery.
Investigating people with bowel symptoms uses a test that detects traces of blood in the stools, the FIT test. There are many possible reasons for positive tests. A few people have cancer. However, most participants with symptoms don't have any serious bowel disease but have benign problems such as piles or irritable bowel syndrome (IBS). It is very difficult to diagnose on symptoms alone, those participants who have serious bowel disease and those who do not. After a positive test, people are invited for colonoscopy - a sort of articulated tube that is passed up the bowel. Most people invited for colonoscopy don't have cancer. Only about 5% of those with positive FIT tests have cancer. About 25% have other bowel diseases, but most have nothing serious wrong at all. So they have the inconvenience and discomfort of colonoscopy but don't get any benefit from it. The investigators want to try adding another test, the volatile organic compound (VOC) test, to see if the investigators can separate those with positive FIT tests who do have something wrong, from those who don't. The VOC test uses a urine sample. Using both tests might also be better for detecting cancer. FIT alone misses about 20%. So the investigators think that using both tests might not only be better for detecting cancer, but also might mean that a lot of people will avoid having to have colonoscopy. This study will recruit 1,819 participants with bowel symptoms from NHS trusts in the UK. They will provide stool samples for FIT and urine for VOC analysis. They will have colonoscopy to get a definite diagnosis. Then the investigators will look at their FIT and VOC test results to see if in future, people with both tests negative.
