Zinc Oxide Versus Petrolatum Following Skin Surgery
Surgical IncisionSurgery--Complications4 morePatients undergoing routine surgery in the Department of Dermatology for any indication on non-scalp skin and closed in linear fashion with scar greater than or equal to 4.5cm in length will be invited to participate in this split scar, head to head study comparing zinc oxide and petrolatum. Patients will apply respective ointments to each half of scar daily for one month and maintain a log of these activities. They will be seen at 1 week, 4 weeks, 8 weeks, and 6 months post-operatively for photographic scar assessment and to complete the patient portion of the Patient and Observer Scar Assessment Scale (POSAS), a quantitative objective assessment of scar appearance. Trained observers (board-certified dermatologists) will score the observer portion of the scale. POSAS outcomes, post-operative infections, linear density of epidermal seal will be assessed at the 1 week, 4 weeks, 8 weeks, and 6 months post-operative periods and compared between the two groups. Participants will have parking validated for all visits and upon completion of all portions of the study will receive a standardized skin care gift bag containing samples for hypoallergenic skin care products (washes, moisturizers, etc.).
Oasis Donor Site Wounds Post-Market Study
Surgical WoundWound2 moreThe purpose of this study is to demonstrate the safety and performance of Oasis extracellular matrix (ECM) when used as a treatment for donor site wounds in the United Kingdom. Oasis ECM is commercially available for the treatment of partial and full-thickness skin wounds, including chronic wounds, wounds from trauma, and wounds that occur during surgery, such as donor site wounds. The ability of the Oasis ECM to promote the healing of donor site wounds will be evaluated in this study. About 40 patients (20 in each arm) over 16 years old will be involved in this study at one center in the United Kingdom.
DACC in the REduction of Surgical Site INfection
InfectionBacterial5 moreSurgical site infection is an infection at a place in the body where surgery has taken place, and has been reported in around 5% of people undergoing an operation. In vascular surgery, infection rates are as high as 30%. Methods to reduce this rate of infection should be investigated thoroughly for their effectiveness and cost-effectiveness. The investigators aim to conduct a research trial examining one such method. Leukomed Sorbact is a wound dressing coated with a chemical (DACC) derived from spider-silk that interacts with, and binds bacteria, causing them to be mechanically removed from a wound when the dressing is changed.The trial aims to compare the effectiveness of this dressing to a standard, non-coated dressing, in the reduction of surgical site infection. 718 patients from a number of centres across the UK will be recruited to this study. Adult patients who are having a vascular surgery operation will be approached for entry into the trial. The trial will be explained to them, as well as an explanation that participation is voluntary and their operation or other aspects of their care will not be impacted in any way should participants not wish to participate. Participants will be randomised by computer into one of two groups - one group whose wounds are dressed with Leukomed Sorbact, and the other whose wounds are dressed with a standard dressing. Patients will be followed up at 5-7 days and 30 days, and at 1 year. At the follow up, their wounds will be inspected for infection, and participants will be asked to complete short questionnaires measuring quality of life. The trial will aim to answer a number of questions, with the primary question being does a DACC coated dressing applied after an operation reduce the risk of an infection at the surgery site? It will also ask whether this treatment is cost-effective and whether it promotes satisfactory healing. A Study Within a Trial will validate a remote diagnostic measure for detecting surgical site infection using wound images and the Bluebelle Wound Healing Questionnaire.
Single Incision Laparoscopic Cholecystectomy Compared With Conventional Laparoscopic Cholecystectomy,...
CholecystectomyLaparoscopicLaparoscopic cholecystectomy has been accepted and is nowadays considered as the gold standard treatment of gallstones disease. Conventional laparoscopic cholecystectomy (CLC) was defined as three or four port surgery carried out with either French or American position. It reduced post-operative pain and shorten post-operative length of stay compared with open cholecystectomy in a great extent. Single-incision laparoscopic cholecystectomy (SILC) as a revolutionized surgery, the main reason for its widespread use being the following: less post-operative pain, faster recovery, better cosmetics and quicker return to full activities, all resulting in the improvement of post-operative quality of life. SILC uses the umbilicus as a natural orifice allowing easy access to peritoneal cavity, easy conversion to standard laparoscopy and its easy closure, has been widely introduced into the clinical practice for benign gallbladder diseases. SILC can easily hide the surgical scar inside the umbilicus, thus has better cosmetic effect. But the real clinical benefits for patients still remain a matter of debate. In the last 5 years, many studies on SILC have been published, trying to answer the question whether such a new approach is worthwhile or not and whether is safe and cost-effective.Based on the above controversy, we conduct a RCT comparing clinical and peri-operative outcomes, such as quality of life (QOL), of SILC and CLC with the intent to assess the actual indications of the single-incision approach.

Perioperative Respiratory Care and Outcomes for Patients Undergoing High Risk Abdominal Surgery...
InfectionPneumonia10 morePENGUIN is a pragmatic multi-center trial investigating the effects of pre-operative mouthwash and perioperative oxygen on the incidences of pneumonia and surgical site infection (SSI) following major abdominal surgery. Patients will be recruited from low and middle income countries and randomly assigned to a trial treatment arms: a) pre-operative chlorhexidine mouthwash and 80-100% FiO2; b) no pre-operative mouthwash and 80-100% fraction of inspired oxygen (FiO2); c) pre-operative chlorhexidine mouthwash and 21- 30% FiO2; or d) no pre-operative mouthwash and 21-30% FiO2.
PLASOMA Ultimate Safety & Efficacy Study
Diabetic Foot UlcerVenous Leg Ulcer5 moreThe purpose of the PULSE study are the followingL A.To perform post market clinical follow up (PMCF) on safety and efficacy: Safety: To confirm transient short-terms side effects and verify long-term/outstanding risks. Efficacy: To confirm the performance of PLASOMA, i.e. the beneficial effect on bacterial load. B. Determine the effect of PLASOMA on wound surface area. A secondary purpose is to examine the beneficial effects of PLASOMA on wound healing and to perform a health technology assessment (HTA). This clinical study will be an open label two-armed randomized controlled trial (RCT), performed at at least three sites (multi-center) in the Netherlands. The two arms are: Control group: Standard wound care for 12 weeks or until healing, whichever occurs first; Treatment group: Standard wound care + PLASOMA treatment for 12 weeks or until healing, whichever occurs first. The frequency of PLASOMA treatment will be determined by the treating (para)medical professional based on the number of visits they would schedule for the standard wound care at the study site. For all study subjects, the treatment frequency will be at least once per week (in order to have enough treatments for safety evaluation) and should not exceed once per day. Follow up (FU) will be performed at three timepoints for both arms: FU1: 2 weeks after end treatment period FU2: 12 weeks after end treatment period FU3: 12 months after start treatment.

Optimal Antibiotics for Operated Diabetic Foot Infections
Diabetic Foot InfectionSurgical Wound2 moreDiabetic foot problems, especially infections (DFI), require multiple resources including iterative surgeries and amputations, long-lasting antibiotic therapies, education, off-loading and eventually revascularization and appropriate foot-ware. Treatment is complicated, multidisciplinary, and marked with a high risk of recurrences. This is a retrospective and prospective cohort with side studies of pathologies and academic research questions that cannot be separated from each other. The investigators establish a retro-and prospective cohort of diabetic foot problems (ambulatory and hospitalized patients) and perform side studies to reduce the incidence of complications, and to reduce recurrences of DFI, cost and adverse events related to therapies. Cohort: Prospective and retrospective cohort of all diabetic foot problems with emphasis on surgical and infectious variables. Trial 1 (Randomized trial on residual infection after amputation): Determination of the level of amputation per MRI followed by a randomization concerning the duration of post-amputation systemic antibiotic therapy, if there is residual bone infection. Trial 2 (Randomized trial on infection without amputation): Determination of the duration of systemic antibiotic therapy in diabetic foot infections without Amputation of the infection.
