Filter by:In this study we aim to develop an automatic pelvic artery segmentation algorithm, which is required for future clinical implementation of US registration for surgical navigation. Various registration methods will be evaluated with the data of this study to obtain most optimal results. If automatic segmentation and registration is successful, the final accuracy of the developed US registration method for tumor tracking should be evaluated in future studies in patients eligible for surgical navigation. Eventually, we aim to replace the CBCT-scan with an automatic tracked US registration pipeline for a more efficient and accurate registration procedure, which could improve the applicability and accuracy of surgical navigation and patient outcomes.
Abdominal surgery is usually associated with severe postoperative pain. The transverse abdominal plane (TAP) block is considered an effective means for pain control in such cases. The quadratus lumborum (QL) block is another option for the management of postoperative pain. The aim of this study is to evaluate the efficacy and safety of quadrates lumborum blocks and Transversus abdominis plane blocks for pain management after abdominal cancer surgery.
This is a feasibility study investigating the image quality of a new, high-performance cone beam CT (CBCT) used for on-couch imaging during radiotherapy treatments.
Advanced pelvic cancers are uncommon, with treatment being challenging. Around 4000 patients every year need treatment in the UK. Cancers can involve multiple organs and often need radiotherapy and chemotherapy before surgery. Surgery usually requires removal of multiple pelvic organs, including muscles, bone, and skin around the anus (the perineum). This can lead to complications relating to both the empty pelvis syndrome and closure of the perineal defect. Reconstruction is challenging, with frequently occurring complications, reducing speed of recovery and quality of life. This study investigates complication frequency, quality of life and expenses following different reconstruction techniques. The investigators hope to improve patient and doctor decision-making in this area and find the best methods of reconstruction to improve outcomes. REMACS has three work packages: 1. Maintenance of a database of patients undergoing colorectal surgery at Southampton and Salisbury Hospitals, including those undergoing extra-levator abdominoperineal excision and pelvic exenteration. This includes clinical data, imaging, health resource use, and patient reported outcome measures. 2. A collaborative national prospective cohort study investigating morbidity, health resource use, longitudinal quality of life outcomes (EORTC QLQ-C30 and disease-specific modules) and quality adjusted life years. The investigators will also assess financial toxicity using the comprehensive score for financial toxicity. 3. A qualitative study using semi-structured interviews to undertake a more complex evaluation of quality of life and patient experiences in patients that have recovered from their surgeries.
Background: At present, effectively implementing smoking cessation programs in the health care system constitutes a major challenge. A unique opportunity to initiate smoking cessation focuses on smokers scheduled for surgery. These patients are not only highly motivated to quit smoking but also likely to benefit from a reduction in postoperative complications which may translate into a decrease of costs. Nevertheless, surgical patients are not routinely informed about the benefits of preoperative smoking cessation. Potential reasons for this missed opportunity may be lack of time and training of surgeons and anesthesiologists. The investigators therefore aim to analyse the impact of a preoperative high-intensity smoking cessation intervention on surgical complications up to a 90-day postoperative period in patients of various surgical disciplines. The hypothesis is that preoperative smoking cessation program improves outcomes in smokers undergoing intermediate to high-risk surgery. The primary objective is to compare complications between patients with an institutional multifaceted smoking cessation intervention starting four weeks before surgery compared to patients in the advice only group (control group) within a 90-day postoperative period. The primary endpoint is the Comprehensive Complication Index (CCI®) within 90 days of surgery. Secondary outcomes include length of hospital stay, cost of hospital stay, smoking abstinence, reduction in nicotine consumption. Methods: The present study is a single center, randomized trial with two parallel groups of smokers scheduled for surgery comparing surgery alone and surgery with preoperative smoking cessation. The investigators plan to randomize 251 patients. The primary endpoint is the Comprehensive Complication Index up to a 90-day postoperative period. The secondary endpoints include comparison of smoking abstinence, quality of life, mental health, length of stay, costs of care and difference in hospital reimbursement between the two groups. Discussion: The hypothesis is that preoperative smoking cessation program improves outcomes in smokers undergoing surgery.
There is a general concern that the backlog of cancer patients waiting for surgery during this period is going to increase and the general impact on patients isolated in their homes is going to cause potential physiological and psychological impairments. Therefore, we propose a distanced-delivered personalized home-based prehabilitation program to all cancer patients scheduled for surgery at the MUHC. The program will be delivered by qualified professionals, supported by technology provided by POP, to all cancer patients waiting for surgery, addressing the patients' risk factors in patients' pandemic reality perspective. Participant contacts will primarily occur virtually using technologies such as video conferencing and digital applications. This will enable us to continue to support people with cancer and deliver safe remote counseling by specialist healthcare providers in their own homes, whilst adhering to the Governmental guidelines on social distancing, self-isolation and shielding.
Background Thoracic or abdominal surgeries are followed by a shorter or longer period of immobilization and after major surgery there is a higher risk of developing cardiorespiratory complications. To prevent these complications, the patient is encouraged to change position and exercise in bed, get out of bed as early and as much as possible after the operation and to breathe with or without aids. There is no general definition of early mobilization and may start within a few hours to a few days after surgery. There is currently a lack of knowledge nationally and internationally about when the mobilization starts and what it contains. Many patients also receive breathing training in connection with the surgery. There is currently no consensus on which method is preferable for which groups of patients. There are similarities and differences in practice in the world regarding postoperative breathing training. There are studies that have mapped practice after primarily thoracic surgery but also abdominal surgery. However, there are no studies that have mapped when the prescribed breathing training starts after different types of operations. The purpose of the study is to map when mobilization and breathing training starts after abdominal and thoracic surgery and what is then performed Method The study will be carried out as a quality follow-up with mapping of practice. Patients ≥ 18 years of age who are undergoing a planned or acute open, keyhole or robot-assisted surgery, who are extubated and who breathe spontaneously will be included. Exclusion criteria are completed plastic, trauma, orthopedic or transplant surgery. The material will be recruited from Swedish university hospitals and county hospitals for 20 days of surgery (Monday through Thursday) for five consecutive weeks. Clinical benefit The study will mean that clinical practice is presented which, with regard to mobilization, is the first study ever that will present when this takes place and what is done and, with regard to breathing training, the first that shows when this training is initiated.
Malnutrition occurs frequently in patients with cancer during and after radiotherapy to the gastrointestinal (GI) area and can lead to negative outcomes. N-3 fatty acids from fish, especially eicosapentaenoic acid (EPA) may possess anticachectic properties. The aim of this study is to investigate the effect of two nutritional interventions; dietary counselling and an oral nutritional supplement (ONS) containing 2.2 g of the n-3 fatty acid EPA (Forticare®) or standard care, including dietary counselling and protein supplementation when needed.
A more recent competing technology for implementing the DIBH technique is real-time surface photogrammetry using the AlignRT system (Vision RT Ltd., London, UK). AlignRT system use non-ionization near infrared light to track patient surface motion. The system has one projector projecting near infrared optical pattern on patient surface. The optical pattern is imaged by optical cameras (two per pod) at ~25 Hz. The user selects a region-of-interest (ROI) on the surface and the software calculates and displays the real-time position in six degrees (3 translations and 3 rotations) in real-time. Once the patient has matched the pre-determined DIBH position (within threshold accuracy), the radiation beam is enabled to be turned on for treatment.
