Laparoscopic pancreaticoduodenectomy was first performed by Garner and Pomp in 1994. This is a technically difficult, time consuming and high rate of complication procedure. The reason is that duodenum and head of pancreas locate deeply in retroperitoneum and are surrounded by important structures such as inferior vena cava, abdominal aorta, superior mesenteric artery, superior mesenteric vein (SMV), portal vein (PV) and hepatic arteries. Injuring these structures during the surgery can lead to life-threatening complications. Moreover, doing anastomoses through laparoscopy, especially pancreatic anastomosis, is more difficult and takes more time than through open approach. The outcome of PD has improved over the last two decades due to advances in surgical techniques, anesthesia and perioperative care. Although studies from high volume centers demonstrate reduce in the operative mortality to less than 3%, the postoperative morbidity rate is still ranging from 30% to 60%. Laparoscopic surgery is being used increasingly as a less invasive alternative to traditional interventions for pancreatic resection. Laparoscopic pancreaticoduodenectomy (LPD) is a difficult procedure that has become increasingly popular. Nevertheless, comparative data on outcomes remain limited. In this prospective study, investigators evaluate the safety and feasibility of surgical and oncological outcomes of minimally invasive PD.
The purpose of this randomized controlled clinical trial is to investigate the effects of epidural block on overall survival，disease-free survival and recovery in patients with pancreatic cancer undergoing distal pancreatectomy. This study will also evaluate the effects of this technique on neuroendocrine, stress and inflammatory response in these patients.
This study will investigate the tumor-associated vasculature of patients with solid tumors. The investigators will use a technology known as intravital microscopy (IVM) in order to visualize in real-time the vessels associated with solid tumors. The IVM observations may determine if an individual patient's tumor vessels would be amenable to receiving systemic therapy, based on the functionality of the vessels.
A Phase II Clinical Trial of the Safety and Efficacy of Fruquintinib in Advanced Pancreatic Cancer Patients Who Failed Second-line Gemcitabine or 5-FU Based Chemotherapy
Surgical resection is the only option for cure for patients with a resectable tumor located at the head of the pancreas. At the time of diagnosis, these patients often suffer from jaundice. Studies have suggested, that jaundice might increase the risk of developing a serious postoperative complication. Preoperative biliary drainage is widely used, because it is considered to improve the surgical outcome and reduce the amount of postoperative complications. There are also studies that suggest the opposite. In these studies the overall complication rate with patients who underwent preoperative biliary drainage was higher than in the patients who were operated right away. A significant amount of these complications were related to the biliary drainage process itself. However, preoperative biliary decompression is widely used in many centers as many surgical centers don't possess the needed resources to arrange early surgery. The benefits and risks of this procedure remain unclear. This multicenter trial aims to compare the surgical outcome and the rate of serious complications in patients who proceed directly to early surgery and patients who have preoperative biliary drainage.
The aim of our study is to evaluate S-MRCP, in comparison to direct pancreatic function, to measure pancreatic exocrine function in patients who have symptoms suspicious for insufficiency. We hypothesize that S-MRCP imaging parameters will correlate well with the direct pancreatic exocrine functioning.
This is a phase 1, open-label study to evaluate the safety and tolerability of neoantigen personalized mRNA tumour vaccine combined with Adebrelimab (a PD-L1 humanized monoclonal antibody) in patients with surgically resected pancreatic adenocarcinoma.
This study wants to find out how safe and effective the use of Folfirinox combined with Stereotactic Body Radiation Therapy )(SBRT) is for the treatment of pancreatic cancer.
It is hypothesized that circulating tumor cells (CTCs) from pancreatic adenocarcinoma are released into the peritoneal cavity through blood lost during the surgical resection of these tumors resulting in peritoneal recurrence despite appropriate surgical resection. Targeting the mechanisms responsible for CTC adhesion to the peritoneum may result in inhibition of implantation and growth, thus preventing this mode of pancreatic cancer recurrence postoperatively.
This is a prospective observation cohort study to evaluate efficacy of different types of adjuvant therapy strategies, including chemoradiotherapy, chemotherapy alone, or no adjuvant treatment, for pancreatic ductal adenocarcinoma patients who received surgical resection of primary cancer.
