Filter by:Pancreaticoduodenectomy (PD) is the treatment of choice for resectable periampullary cancer. PD is still associated with a relatively a high incidence of delayed gastric emptying. And, there are no acknowledged strategies to avoid DGE. Several feeding strategies have been investigated to cope with this problem. However, there is still no consensus concerning the best nutrition support method after pancreaticoduodenectomy. The purpose of this study is to determine the effect of nutrition support methods on DGE after pancreaticoduodenectomy: early enteral nutrition or total parenteral nutrition. Patients undergoing pancreatoduodenectomy will be randomized to receive early enteral nutrition (EN group), or Saline administration (Saline group), or oral intake only (Natural control). The EN group will receive standard enteral diet administered through a nasojejunal tube. Enteral nutrition will be started on the 1st postoperative day and increased daily by 20-40 ml up to the estimated level. The Saline group will receive saline administered through a nasojejunal tube beginning from the 1st postoperative day. Oral intake will not be restricted in all three group.
This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.
This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.
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).
The primary objective of this study is to assess the safety, tolerability and toxicity of preoperative HBOT in patients undergoing a pancreaticoduodenal resection for premalignant and malignant tumors of the common bile duct, periampullary and duodenum.
This study will evaluate the performance of the EnLightTM and LightPathTM Imaging Systems in detecting tumour lesions in patients with gastric, pancreas, bile duct or duodenal cancer. EnLightTM will be used to detect positron emission and the LightPathTM system to detect Cerenkov Luminescence. Both are emitted by the Positron Emission Tomography (PET) agent. The study will also evaluate the patient safety and radiation safety of the EnLightTM, and the safety for the device operators and surgical staff of the LightPathTM Imaging System.
Improvements to treatment strategies for patients with cancers of the upper gastrointestinal tract have produced a large population of people who remain free from cancer recurrence in the long term following treatment. Surgery is the cornerstone of treatment for patients with these cancers, but while surgical removal of the tumour may offer the best chance of cure, these are major operations associated with specific long term complications. Weight loss and poor nutrition are common problems among patients who attain long-term cancer remission and cure after surgery. The mechanisms underlying these problems are not well understood and therefore treatment options are limited. Our research has demonstrated increased levels of chemical messengers (gut hormones) released from the gastrointestinal tract after meals in patients who have previously undergone this type of surgery. These chemical messengers play a role in controlling appetite and interest in food, and increased levels after surgery may reduce interest in eating. Understanding the role of gut hormones in the control of appetite may allow us to use certain medications to block gut hormones and hence increase appetite, allowing patients to eat more and regain weight, preventing nutritional problems after surgery. In this study, the investigators aim to determine whether exaggerated gut hormone secretion causes reduced appetite and interest in food after surgery. The information gained from this study may help us to develop treatments for patients with weight loss and nutritional problems after surgery.

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.
Patients who underwent major gastrointestinal surgery is potentially at risk of malnutrition due to reduced oral intake, increased nutritional need, reduced gastrointestinal absorption function, and/or metabolic changes after surgery. The postoperative malnutrition is associated with low quality of life and seems to be related long-term nutritional status. This study is a multicenter, open-labeled prospective randomized clinical trial to examine the effect of postoperative oral nutritional supplements (ONS) after major gastrointestinal surgery by comparing the change of body weight and other nutritional parameters between the experiment group that is supplied with ONS and the control group without ONS.
