Filter by:The goal of this randomized controlled trial is to compare uncovered, partially covered, and fully covered self-expandable metal stents (SEMS) in the palliative treatment of distal malignant biliary obstruction in a Swedish multicenter study. The main questions it aims to answer is: Is the stent patency rate different depending of stent type? Is the stent patency time different depending of stent type? Is the patient survival different between the groups? Which complications are seen, and do they differ between the groups? Are there different mechanisms behind the stent failure depending on stent type? Patients will at ERCP, with a guidewire passed through the stenosis in the bile duct, be allocated to either uncovered, partially covered, and fully covered (SEMS). Totally, 450 patients will be recruited, 150 in each study arm, according to the power analysis. Patients will be followed in a monthly surveillance by a study nurse up to 12 months after stent insertion. Endpoints are: alive after 12 months with a patent stent, death with a patent stent, stent dysfunction with a subsequent intervention i.e. repeated ERCP or PTC = "objective stent failure", stent dysfunction, jaundice or cholangitis, but not intervention has been undertaken due to a poor condition of the patient, "clinical stent failure", the patient has undergone curative surgery or a bilio-enteric by-pass (a gastro-enteroanastomosis or a duodenal stent is not a reason for exclusion), the patient refuses further follow-up.
The purpose of this study is to assess the efficacy of modulated mid-frequency whole-body electromyostimulation (WB-EMS) combined with nutritional therapy in patients with gastrointestinal cancer.
This phase II trial compares the effect of rectus sheath block with liposomal bupivacaine to thoracic epidural analgesia (TEA) on pain control in patients following surgical removal of all or part of the pancreas and duodenectomy (pancreatoduodenectomy). Administering long acting local anesthetics, such as liposomal bupivacaine, in between the muscle layers of the abdomen (rectus sheath block) may help with pain relief during and after surgery. TEA uses a needle to insert a flexible plastic catheter into the thoracic spine to administer anesthetic and pain medication, such as bupivacaine and hydromorphone, to treat pain in the thoracic and upper abdominal areas during and after surgery. Epidurals have been successfully used to treat pain after surgery, however, it does have a risk of low blood pressure which may limit the use in the thoracic approach. Rectus sheath blocks with liposomal bupivacaine may be as effective as TEA in reducing pain in patients following a pancreatoduodenectomy.
The incidence rate and mortality rate of periampullary cancer at home and abroad both show an increasing trend, seriously affecting the health level of the people. Pancrecoduodenectomy (PD) is the only effective treatment for periampullary cancer. However, due to the complex technology and difficulty of PD surgery, laparoscopic pancreaticoduodenectomy (LPD) is more difficult, and the postoperative mortality can reach 5%. The important reason is the most serious complication- -pancreatic fistula. The occurrence of pancreatic fistula is related to many factors, and the most critical factor is the method and technology of pancreatico-intestinal anastomosis, so the improvement and innovation of pancreaticoco-intestinal anastomosis technology has always been a hot topic in surgical clinical research. Blumgart Pancreatic anastomosis was originally created by Professor L.H.Blumgart in the United States, and was widely used in OPD due to its low incidence of pancreatic fistula. However, the traditional Blumgart anastomosis is complicated and is not suitable for application in LPD. According to our own experience, our team simplified and improved the traditional Blumgart anastomosis to OPD, and through retrospective study, it has the advantages of reducing the incidence of pancreatic fistula. However, the application value in LPD still needs to be further discussed. Therefore, this study intends to use a prospective randomized controlled trial, using the LPD patients with traditional Blumgart pancreatecointestinal anastomosis as the control group, and the LPD patients with modified Blumgart pancreatecointestinal anastomosis as the test group, compare the clinical relevant indicators and the incidence of postoperative complications, and explore whether the application value in LPD can truly simplify the surgical procedure and ensure the lower incidence of pancreatic leakage.
This is a patient registry for all cases of pre-neoplastic or early neoplastic digestive tract lesions treated with curative intention by endoscopic submucosal dissection (ESD) technique.
Endoscopic resection of gastrointestinal lesions may prevent cancer. However, resection is associated with adverse events such as bleeding. Tranexamic acid (TXA) is a synthetic derivative of lysine that exerts antifibrinolytic effects and may prevent bleeding. The investigators aim to evaluate the effect of local TXA on preventing intraprocedural and postprocedural bleeding in patients undergoing endoscopic mucosal resection (EMR) of upper gastrointestinal lesions.
There is currently no reliable evidence on the safety of CSP (cold snare polypectomy) / p-CSP (piecemeal CSP) for SNADT greater than 6mm.In this prospective historical controlled study, we intend to test the role of CSP / p-CSP in the treatment of pedicle less snadt greater than 6mm compared with EMR (endoscopic mucosal resection) / EPMR (endoscopic piecemeal mucosal resection).
The purpose of this study is to prospectively determine the effects of administering proton pump inhibitors (PPIs) following pancreaticoduodenectomy on postoperative outcomes. The findings of this study will help in avoiding the widespread use of PPIs during the immediate postoperative period following pancreatic surgery.
The aim of this study is to examine the long-term outcomes after curatively intended resection of duodenal adenocarcinoma.
Cancers of the upper gastro-intestinal tract, including esophagus (gullet), stomach and small bowel, are amongst the deadliest malignancies. The main reason for their high mortality rate is that they are usually diagnosed late when curative treatments are no longer effective. However, these types of cancer generally arise from well-described pre-cancerous diseases, such as Barrett's esophagus and gastric intestinal metaplasia. This provides an opportunity for clinicians to detect these pre-cancerous conditions early and offer adequate cure or clinical monitoring before they progress to cancer. A camera test (gastroscopy) is the gold-standard test to detect pre-cancerous diseases in these organs. There has been limited research to set the standards for performance of a gastroscopy, especially with regards to diagnosis of pre-cancerous conditions, which require knowledge and skills by the physician performing the test (endoscopist). Therefore, the hypothesis behind this study is that the aforementioned pre-cancerous diseases are understudied and often go undetected. This study aims to understand how often endoscopists should diagnose these pre-cancerous diseases on routine gastroscopy and help define the standards to measure performance. The investigators will assess the following rates: i. how often endoscopists diagnose these pre-cancerous lesions during endoscopy; ii. How often these conditions are diagnosed on biopsies taken according to a standardized protocol; iii. How often these condition should have been diagnosed by the endoscopists based on the review of pictures by expert endoscopists. The investigators will also compare the rates of correct diagnosis by endoscopists with different levels of experience and based on the times spent to complete the diagnostic test. Investigating these aspects will enhance the understanding of the medical community with regards to the diagnosis of these pre-cancerous lesions and set endoscopy standards to improve their early detection and treatment before they progress to cancer. This will translate to improved cancer prevention and benefit for patients.
