Filter by:In this feasibility study (non-randomized), the applicability of a new "moving cell" biliary stents (by HILZO) in Klatskin tumors (bile duct obstruction) will be investigated. The HILZO Moving-Cell Stent to be examined here is a non-coated metal stent with a novelty. The meshes have a diameter of 4 mm, which is rather small compared to most other stents. This significantly increases the radial force and thus the stability of the stent. Furthermore, ingrowth by tumors in the stent is difficult. The special feature is that the individual meshes can easily be stretched to 10 mm without changing the stability of the stent. This allows a second stent to pass through the first to another segment of liver.
In this randomized trial two two self-expanding metal stents (SEMS) for treatment of malignant biliary strictures are investigated. A newly developed PTFE (Polytetrafluorethylen) (Teflon) stent is tested versus standard covered metal stents. PFTE (Teflon) coating promises improved formability over standard silicone-coated stents, easier removal through the soft surface, and significantly reduced tumor growth through the impermeable surface.
Major surgery is a stressful procedure; good recovery after surgery is important to patients and their doctors. Studies done at the McGill University Health Centre (MUHC) with cancer patients awaiting surgery have shown that exercise combined with simple diet recommendations (which may include a supplement) and relaxation techniques before surgery helped speed up the ability to resume walking after surgery. These results have made the investigators aware that exercise and good nutrition are as important before surgery as they are after surgery; while it is common practice to start strengthening the body after surgery (rehabilitation), there may be some advantage to begin this process before surgery (prehabilitation). The purpose of this study is to see if the following program, either before or after surgery, can help patients recover from liver, pancreas or bile duct surgery: 1. Exercise that may help participants move and breath better, 2. Nutrition advice and a supplement to make participants strong, 3. Relaxation and anti-anxiety tips to help cope with the stress of upcoming surgery The investigators will see if following this program will have an effect on participants' ability to walk before and after surgery.
Investigators asses whether there is any difference in short term recovery and long term prognosis according to the anesthetic method in patients who undergoing pancreatic cancer and bile duct cancer and undergoing surgery for PPPD or distal pancreatectomy.
Endoscopic retrograde cholangio-pancreatography (ERCP) is advanced endoscopic technique that allows minimally invasive management of biliary and pancreatic disorders. However, the incidence of infectious complication of ERCP is considerable. Transient blood stream infection after ERCP has been reported in a high ratio, up to 27% and post-ERCP infection accounts for about 10% of the major complications associated with mortality. Although prophylactic use of antibiotics is generally not recommend in all cases, debates about the prophylactic use of antibiotics continues and prophylactic use of antibiotics is recommend in case of ERCP that incomplete biliary drainage is expected. In this study, researchers will use prophylactic antibiotics in patients with biliary obstruction who have high-risk of post-ERCP bacteremia. Antibiotics regimen is selected based on the data of our institution, and administered to patients before ERCP procedure.
This study aims to evaluate whether the incidence of delayed gastric emptying (DGE) can be reduced by proximal Roux-en-y gastrojejunal anastomosis in comparison with the standard gastrojejunal anastomosis in pylorus-resecting pancreaticoduodenectomy (PrPD).
In this study, participants with multiple types of advanced (unresectable and/or metastatic) solid tumors who have progressed on standard of care therapy will be treated with pembrolizumab (MK-3475).
The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.
The purpose of this study is to investigate whether perioperative immunonutrition has additional effects on cell-mediated immunity in patients undergoing pancreaticoduodenectomy.
Background: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: - Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. - Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: - Before their procedure, participants will have a small blood sample taken. - Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. - For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. - Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.
