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.
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.
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 study aims to retrospectively investigate the endoscopic resection procedures of cancerous and precancerous lesions of the upper and lower digestive tract in order to evaluate the efficacy and safety outcomes and to compare different resection techniques. In particular, the resection techniques investigated will be mucosectomy, en bloc and piecemeal, endoscopic submucosal dissection (ESD) and its variants, full-thickness resection. The anatomical districts involved will be the esophagus, stomach, duodenum, colon and rectum.
Subepithelial lesions (SEL) are incidentally observed in the stomach of about 0.3% of middle-aged men and women; half of these are neoplastic. The incidence of subepithelial tumors (SET) of gastrointestinal (GI) origin has risen twofold to fivefold within the past 30 years.The etiology of most SMTs cannot easily be determined by endoscopy. So, we aim to estimate the prevalence and types of sub-epithelial lesions among patients undergoing EGDs in Egypt.
The Quebec Pancreas Cancer Study is a prospective clinic-based study consisting of clinical, family history and epidemiologic data, with accompanying biospecimens, from patients diagnosed with either pancreas cancer, a related cancer or a related pre-cancerous condition, and their families.
Magnetic anastomosis has been attempted in biliary and intestinal reconstruction. Based on our initial experience, the investigators have successfully utilized magnetic anastomosis for biliojejunostomy and pancreaticojejunostomy during pancreaticoduodenectomy. The current study was to design a prospective and case-control study with utilization of magnetic compression anastomosis for pancreaticojejunostomy and biliojejunostomy in Whipple's procedure versus traditional hand-sewn technique on the postoperative morbidity, such as biliary/pancreatic fistula, hemorrhage, anastomotic stenosis, etc. In addition, the investigators are seeking to assess the safety and formation of the anastomosis by magnetic technique.
Traditional Chinese medicine (TCM) syndrome is a core foundation of disease knowledge, clinical diagnosis and treatment and curative effect evaluation in TCM. "Same TCM Syndrome for Different Diseases" and "Same Treatment for Different Diseases" is one of the characteristics of TCM syndrome differentiation and treatment. This study is the "TCM disease syndrome combination" research baced on principles and methods of system biology, which is through acquisition of primary hepatocellular carcinoma (HCC) and colorectal cancer patients with TCM syndrome information, detection of clinical indicators and genomic, proteomic, and metabolites changes, analyzing the correlation between TCM syndromes and biological information, and revealing its biological material characteristics and the molecular mechanisms of "Same TCM Syndrome for Different Diseases";Developing and implementing the program of TCM syndrome differentiation and treatment for HCC and colorectal cancer to evaluate the efficacy of TCM syndrome based-treatment of HCC and colorectal cancer with TCM syndrom scores, clinical and systems biological indicators, quality of life and survival rate, and to revealing the mechanism of the "Same Treatment for Different Diseases".
