Filter by:Chronic radiation-induced injury (CRII) is a common complication after radiation therapy for pelvic malignancies. Resection surgery could be an optimal surgical approach when CRII is complicated by late complications. However, because of high incidence of postoperative complications like anastomotic leakage rate and mortality, doctors try to avoid performing surgical resection. In addition, there is sparse agreement on the types of surgery. Previous study proved that anastomosis with at least one end of bowel without radiation damage can greatly reduce postoperative anastomotic leakage rate and mortality. And in Bacon surgery, primary anastomosis is not performed, and the anastomotic tension markedly reduced and the blood supply of anastomosis can be judged intuitively to improve the quality of anastomosis in the second stage of intestinal anastomosis to decrease the anastomotic leakage rate. Combining the advantages of proximally extended resection and two-stage anastomosis could minimize potential complications and maximize the therapeutic efficacy in theory, and a small sample prospective clinical study by the investigator have already preliminarily confirmed it. The investigator has also preliminarily proved that Parks surgery is safe and feasible for the treatment of late complications of CRII. Therefore, this study aims to observe the safety and effectiveness of PE-Bacon surgery with Parks surgery as a control, in order to select more optimal surgical methods and provide a high-level evidence-based medical basis for patients with late complications of CRII.
Our hypothesis is that improved line of sight to patient data, ergonomics, and headset lead shielding in the CCL will lead to behavioral changes in the CCL personnel that will reduce radiation exposure to all members of the team. Further, reducing the burden of large, cumbersome monitors will enable improved use of shielding. Our approach is a single center randomized controlled trial of consecutive patients randomly assigned to one of two groups with group 1 using mixed reality display and group 2 using standard 2D displays to perform diagnostic angiography in the CCL. Radiation exposure will be evaluated at multiple levels including total radiation exposure, exposure of each individual staff member, as well as specific exposure to eyes and head in group 1 versus group 2.
The objective of the study is to evaluate the safety of intramuscular (IM) administration of PLX-R18 in subjects exposed to ionizing radiation and who are at risk of developing HS-ARS. Indication:Post-Exposure Prevention (PEP) or treatment of Hematopoietic Syndrome of Acute Radiation Syndrome (HS-ARS) in subjects suspected to have been exposed to ionizing radiation.
